The reaping machines made by Manny do not infringe McCormick's
patent, either as to the divider, the manner in which the reel is
supported, or the combination of the reel with a seat for the
raker.
McCormick not being the original inventor of the machine called
a divider, but the patentee of only an improvement for a
combination of mechanical devices, could not hold as an infringer
one who used only a part of the combination.
Page 61 U. S. 403
The manner of supporting the reel in Manny's machine is not like
that in McCormick's, and was used before McCormick's first
patent.
With respect to the raker's seat, McCormick's patent was for a
combination of the reel with a seat arranged and located according
to his description. But Manny's arrangement differs from
McCormick's in principle as well as in form and combination, and is
therefore no infringement of McCormick's patent.
The bill which was filed by McCormick alleged that the
defendants in error had infringed his patent for a reaping machine,
called upon them for an account, and prayed for an injunction. The
defendants denied the infringement and claimed a right to construct
their machines under letters patent granted to John H. Manny. The
circuit court dismissed the bill, and McCormick appealed to this
Court.
McCormick's patents had been twice before this Court, as will be
seen by referring to
57 U. S. 16 How.
480, and
60 U. S. 19 How. 96.
The same claims,
viz., the fourth and fifth of the patent
of 1845, were involved in the case in 19 How. and the remaining
claim,
viz., that relating to the seat of the raker, under
the patent of 1847, was before the court in 16 How. only that it
now comes up under a reissued patent in 1853.
The reporter despairs of giving any intelligible account of the
argument in this case. The record was upwards of one thousand pages
of printed matter, of which seven hundred and fifty pages were the
depositions of witnesses, and the courtroom was filled with models
and drawings, introduced upon either side, to which constant
reference was made by the counsel.
MR. JUSTICE GRIER delivered the opinion of the Court.
The bill charges the defendants with infringing two several
patents granted to complainant, for improvements in the machine
known as McCormick's Reaper. One of these patents bears date the
31st of January, 1845; the other on the 24th of May, 1853, being
the reissue of a previous one, dated 23d of October, 1847. The
defendants are charged with infringing the fourth and fifth claims
of the patent of 1845 and the second claim of the reissued patent
of 1853.
I. The first infringement charged is that of the divider, or
that part of the reaping machine which is defined "as an
arrangement
Page 61 U. S. 404
or apparatus for separating the grain to be cut from that which
is to be left standing."
The claim is as follows: "4th. I claim the combination of the
bow L and the dividing-iron M, for separating the wheat in the way
described."
The description referred to is as follows:
"The
divider K is an extension of the frame on the left
side of the platform, say three feet before the blade, for the
purpose and so constructed as to effect a separation of the wheat
to be cut from that to be left standing, and that whether tangled
or not. E is a piece of scantling, say three feet long and three
inches square, made fast to a projection of the platform by two
screw bolts. To the point of this piece, at K, is made fast by a
screw or
bolt a bow L of tough wood, the other end of
which is made fast in the hinder part of the platform at R, and it
is so bent as to be about two and a half feet high at the left reel
post, and about nine inches out from it, with a regular curve. The
dividing iron M is an iron rod of a peculiar shape, made
fast to the point of the same piece E, and by the same screw bolt
that holds the bow L. From this bolt this iron rises towards the
reel S, at an angle of say 30�, until it reaches it, then
it is bent so as to pass under the reel as far back as the blade,
and to fit the curve of it the reel. From the bolt in the point
aforesaid, the other end of this iron extends say nine inches along
the inside of the piece E, where it is held by another screw bolt
M, and where it has a groove or slot in it to admit the other ends
being raised or lowered turning on the point screw K as a pivot to
suit the height of the reel. By means of the bow to bear off the
standing wheat and the iron to throw the wheat to be cut within the
powers of the reel, the required separation is made complete."
The answer denies that the arrangement of the divider used by
defendants for separating the grain to be cut from that to be left
standing is the same in construction or mode of operation as that
claimed by complainant, or a colorable evasion of said claim, and
avers that it is a different and distinct arrangement, invented by
J. H. Manny, after several years' experiments.
It would be a difficult task to make intelligible to the
uninitiated the construction of a very complex machine without the
aid of models or diagrams. But for the purposes of the case, the
divider, although a component part of the great complex machine
called the reaper, may be considered by itself as a machine, or
combination of devices, attached to the reaper to perform certain
functions necessary to complete the whole operation. In order to
ascertain whether the divider used by defendants
Page 61 U. S. 405
infringes that of the complainant, we must first inquire whether
McCormick was the first to invent the machine called a divider,
performing the functions required, or has merely improved a known
machine by some peculiar combination of mechanical devices which
perform the same functions in a better manner.
If he be the original inventor of the device or machine called
the divider, he will have a right to treat as infringers all who
make dividers operating on the same principle and performing the
same functions by analogous means or equivalent combinations, even
though the infringing machine may be an improvement of the original
and patentable as such. But if the invention claimed be itself but
an improvement on a known machine by a mere change of form or
combination of parts, the patentee cannot treat another as an
infringer who has improved the original machine by use of a
different form or combination performing the same functions. The
inventor of the first improvement cannot invoke the doctrine of
equivalents to suppress all other improvements which are not mere
colorable invasions of the first.
That portion of a reaping machine called the divider or
separator may be described as a pointed, wedge-formed instrument
which is attached by its butt at that extremity of the cutting
apparatus which runs in the grain in such manner that its point
projects in advance of the cutting apparatus and enters the
standing grain. Its functions, where the grain stands erect, are to
divide it into two portions, one of which is borne inwards by the
inner side of the wedge formed implement within the range of the
cutting apparatus and of the reel, in case the machine is fitted
with a reel; the other portion of the grain is borne outwards by
the outer side of the divider, so as to be passed by that portion
of the machine which lies behind the cutting apparatus. When grain
is inclined outwards, the function of the divider is not only
merely to divide the grain into portions, but also to raise up the
inclined stalks of the grain, below which the divider passes. When
the grain inclines inwards, the function of the divider is not only
to divide the mass, but also to raise up the inclined stalks of
grain beneath which the divider passes and to bear them outwards
without the range of the reel, if the machine has a reel, and of
the cutting apparatus. When grain, in addition to being inclined,
is also entangled, the divider not only separates and raises the
stalks, but also tends to disentangle them. The lower face of a
divider also performs the function of a shoe or runner, to prevent
the cutting apparatus from digging into the earth when, by any
accidental movement of the machine, it would
Page 61 U. S. 406
otherwise do so. The divider also performs the function of
limiting or regulating the width of the swath by raising up and
turning inwards those stalks of grain which, from their inclination
outwards, would otherwise escape the action of the cutter, and by
raising up and turning outwards those stalks of grain which, from
their inclination inwards, would otherwise be within the range of
the cutter. All dividers perform these functions in a greater or
less degree. The English patent of Dobbs in 1814 had dividers of
wood or metal. The outer diverging rod rose as it extended back,
and diverged laterally from the point to raise the stalks of grain
inclining inwards, and to turn them off from the other parts of the
machine. The patent of Charles Phillips of 1841 had a divider,
shaped like a wedge, performing the same function, turning the
grain aside on both sides of the machine and raising it up.
Ambler's machine had a triangular divider performing the same
functions, as also the machines of Hussey, Schnebly, and that of
McCormick, patented in 1834, which is now public property. The
present claim is for the combination of this bow with a dividing
iron of a certain form, and for nothing more. This dividing iron is
but a new form or substitute for that side of the triangle or wedge
which in other machines performed the function of separating the
inside grain, and raising it to the cutters.
It is described in the patent as having these peculiarities to
distinguish it from those that preceded it.
1. It rises at an angle of about thirty degrees till it reaches
the reel.
2. It is curved under the reel.
3. It is made adjustable by means of a slot, so as to suit the
different heights of the reel.
Its function is to raise and support the grain along the inner
edge of the divider at the maximum elevation consistent with the
employment of the reel. As a form or combination of devices, it is
new and no doubt an improvement, and therefore the proper subject
of a patent. But as a claim for a combination of mechanical devices
or parts it is not infringed by one who uses a part of the
combination. Nor can it challenge other improvements of the same
machine different in form or combination as infringements, because
they perform the same functions as well or better by calling them
equivalents. The machine constructed under defendants' patent has a
wooden projection, somewhat in the form of a wedge, extended beyond
the cutting sickles some three feet, and which, from the point in
front, rises as it approaches the cutting apparatus, with a small
curve not approaching to an angle of thirty degrees, so
Page 61 U. S. 407
as to raise the leaning grain. It has no dividing iron nor
substitute or equivalent possessing the peculiar qualities of that
instrument. It more resembles the wedges in use before McCormick's
patent of 1845. As an improvement on former machines, it has some
peculiarities of form and construction, but it does not adopt the
combination of complainant's patent. It is a distinct improvement,
probably inferior to McCormick's but certainly no infringement of
his claim.
II. The fifth claim of complainant's patent of 1845, which the
bill charges the defendants with infringing, is as follows:
"5. I claim setting the lower end of the reel post R behind the
blade, curving it at R2, and leaning it forward at top, thereby
favoring the cutting and enabling me to brace it at top by the
front brace S, as described, which I claim in combination with the
post."
In the reaping machine of McCormick's original patent of 1834,
he had placed the reel post in front of the cutters. This position
of the post interfered with the action of the reel in drawing the
grain to the cutters, especially in gathering tangled grain. In
order to remedy this defect of his own machine, he set the post
farther back and braced it as described.
Defendant does not support his reel by posts, as was done by
McCormick. He uses the horizontal reel bearer connected by a frame
with the hinder part of the machine. This device for supporting the
reel was invented and used many years before McCormick's first
patent of 1834. It had no reel post situated as in his patent, and
encountered none of the evils remedied by the change in its
position. This attempt to treat the earlier and better device used
by defendant as an infringement of a later device to obviate a
difficulty unknown to the first is an application of the doctrine
of equivalents which needs no further comment.
III. The bill charges defendants with infringing the second
claim of the reissued patent of 1853. This claim is as follows:
"2. And I also claim the combination of the reel for gathering
the grain to the cutting apparatus and depositing it on the
platform, with the seat or position for the raker
arranged and
located as described or the equivalent thereof to enable the
raker to rake the grain from the platform, and deliver and lay it
on the ground at the side of the machine as described."
If this claim be construed to include all machines which have a
reel and a raker's seat, it is void for want of novelty. Hite,
Woodward, Randall, and Schnebly had invented and publicly used
reaping machines which had reels and a place for the raker on the
machine. But the true construction of this claim, and the only one
which will support its validity, is to treat it
Page 61 U. S. 408
as a claim for a combination of the reel with a seat "arranged
and located as described." And such was the construction given to
it by the defendant himself, when the commissioner had refused to
grant him a patent claiming the mere combination of a reel and a
raker's seat, "because such a combination was not patentable, the
functions of each device having no necessary connection with the
other."
This arrangement for the location of a raker's seat was made
"by placing the gearing and crank forward of the driving wheel,
and thus carrying the driving wheel further back than heretofore,
and sufficiently so to balance the rear part of the frame and the
raker thereon."
By this device he obtained a place for the raker over the finger
bar, just back of the driving wheel, and at the end of the reel,
where he could have free access to the grain and rake it off the
machine at right angles to the swath. It was by limiting his claim
to this arrangement, location, and combination that the complainant
obtained his patent, and without this construction of it the claim
is neither patentable nor original.
The arrangement, combination, and location of the raker's seat
by defendants has been patented to Manny as an independent
contrivance and distinct invention. The place for the raker is
obtained by a change in the shape of the platform, different from
any before employed. It differs from the complainant's device in
principle as well as in form and combination. The raker's seat is
on a different part of the machine, where he may stand without
destroying the balance of the machine or tilting it up. It requires
no modification of the reel. It requires no such combination or
modification of parts of the machine in order to find a place for
the raker, which is an essential part of complainant's claim.
It is substantially different, both in form and in combination,
from that claimed by the complainant, and is consequently no
infringement of his patent.
Concurring, as we do, in the opinion and decision of the court
below on these several points, the decree is
Affirmed with costs.
MR. JUSTICE DANIEL dissenting:
In the opinion of this Court just delivered I do not concur.
Protracted as the discussion by counsel in the case has been, the
real grounds for controversy between the parties are obvious, and
comprised within quite a limited compass. The unusual display of
mechanical ingenuity, and the comment upon its progress exhibited
in the conduct of this cause, whilst they evince great zeal and
industry and may afford entertainment to the
Page 61 U. S. 409
curious on such subjects, are in a great degree irrelevant to
and beside any legitimate inquiry which an adjustment of the claims
of the parties either imposes or warrants. In the decree of the
court below as well as in the arguments in this Court, it has been
conceded that the patent of the appellant is strictly legal. This
concession necessarily excludes, and in legal acceptation
concludes, all inquiry as to the right of the appellant to
the full benefit of his invention, either as an original or a
combination, and renders unnecessary and irregular and improper any
and every comparison between that invention and previous claims to
discovery and improvement having in view the same results and the
same or merely equivalent modes of producing them. This
concession therefore narrows down and confines the proper
investigation before this Court, as it should have restricted that
before the circuit court, to the single question whether the
machine complained of as an infringement, either in theory, in
construction, or in operation, was the same with the improvement
invented by the appellant, for the benefit or the reward for which
the law had given its guarantee. This was the proper inquiry before
the court below, is the only regular inquiry here. All others
connected with previous inventions were and must be irregular, and
are excluded and forbidden by the concession that the patent of the
appellant is legal and valid. To guide them in this, the only
legitimate inquiry, this Court has had before it a species of
evidence of all others best calculated to conduct them to the truth
-- evidence superior to and unaffected by the interests or
prejudices of partisans or by the opinions (the reveries, they may
often be called) of a class of men styled experts -- men as often
skillful and effective in producing obscurity and error as in the
elucidation of truth. No witnesses can testify so clearly and so
impartially as do the subjects though mute concerning which a
controversy about identity or dissimilarity is pending. These
witnesses have been produced and their testimony eagerly and keenly
scrutinized, and that testimony establishes, in my judgment, with a
force and certainty which no ingenuity can either withstand or
evade, that the machine put in operation by the appellees is a
palpable infringement of the rights of the appellant; that in
theory or principle, in structure, in the modes of operation, and
in the results proposed, it is essentially, and with some
insignificant and merely apparent diversity,
formally
identical at least in one important particular with the
invention secured by the government to the appellant and admitted
by the appellees and by the court, to have been rightfully and
legally guaranteed to him.
That portion of the machines put in operation by each of
Page 61 U. S. 410
the parties to this controversy, and which constitutes the most
material subject of contention in this cause, consists of what in
the description and specification of the respective patents is
called a "divider." The function and the value of this divider are
experienced in separating the stalks of wheat designed to be
immediately severed by the cutters from those which do not come
within their immediate and regular operation, but which it is
desired should be left to the future or succeeding action of the
machine. It frequently happens in fields of luxuriant growth that
from high winds, heavy rains, and even from its own weight, wheat
is pressed down and becomes, in rustic phrase, "lodged." In this
condition, the stalks and heads of the wheat, on both sides of a
line described by the track of a machine, will become entangled,
and inclined in various and opposite directions accordingly as the
momentum which displaces the natural position of the growing crops
has been applied. In such a condition of the wheat, any process by
which a portion of the crop should be torn apart from portions with
which it was intertwined would prove highly detrimental, inasmuch
as it would necessarily increase the irregularity in the position
of the wheat not cut and standing outside of the regular track of
the machine, and by violently and rapidly rending apart the tangled
straw, would shatter and waste the grain in each division, creating
thereby a serious diminution in the yield or product. In order to
prevent these mischiefs by disentangling the wheat, by separating
that designed to be immediately severed from that reserved for the
succeeding action of the machine, and by raising up the former and
bringing it within the scope and operation of the reel and the
cutters, was devised an addition or appendage to the reaper called
the "divider." The importance of this appendage both to the success
of the reaper and on account of its real utility in practice cannot
be with reason called in question. Its essential importance is
sufficiently evinced by the zeal and industry displayed and the
extraordinary expense which must have been incurred in this
controversy. The divider of McCormick may be thus substantially
described: a pointed instrument or structure, called by the
patentee a "bow," formed of strong hard wood, confined in front and
projecting so far in advance of the cutters as to enter the wheat
in time to effect its preparation for the approach of the cutters.
This bow is extended in a curvilinear form on the outer side of the
machine, next the grain to be separated from the cutters, and is
gradually elevated from the point in front to a degree increasing
towards the rear of the machine, sufficient to disentangle the
straw, and place it in a position proper for the sweep or action of
the returning machine. On the interior side of
Page 61 U. S. 411
the machine, or that on which the grain is to be severed, the
divider of McCormick is constructed of a bar of iron, confined at
the same point with the wooden bow above mentioned as operating
externally, and this iron bar is capable of being so adjusted as to
disentangle and raise the wheat separated from that standing on the
exterior of the machine, and by a lateral and angular direction
given this adjustable bar, as well as by its vertical extension, it
embraces and secures the wheat on the interior side of the machine
and presses it to the action of the reel and the cutters.
Such as has been just described I hold to be McCormick's
divider, and such too its operation and effects. Let us now compare
them with the structure and operation of the structure complained
of as an infringement, in order to ascertain how far the rival
claims of the parties are identical or diverse. And this comparison
will be most fairly and satisfactorily accomplished and the results
most clearly established by a recurrence to that silent but
irresistible testimony already referred to, the testimony of the
machines themselves.
On Manny's machine, the divider on the exterior side, or the
side of the standing grain, is formed of a piece of timber which,
according as fancy shall dictate, may be denominated a "bow" or by
any other appellation which may be preferred. This piece of timber,
like the "divider" of McCormick's machine, is confined in front and
penetrates the standing grain in advance of the cutters. Like
McCormick's divider, it rises obliquely from the stationary point
in front, towards the rear of the machine to a degree intended to
be sufficient to separate and support the straw, and in the same
manner diverges in an angle supposed to be great enough to secure
that separation, and to prevent the breaking down of any portion of
the straw by being pressed to the earth or by being torn away by
the machine in its progress. On the interior side or section of
Manny's divider there is no adjustable iron bar or rod as a part of
the divider, but for this is substituted a piece of timber or a
board, connected and confined in the front of the machine with the
wooden fixture extended on the outside next the standing grain, and
from that point of connection this substituted board is protracted
in a diverging angle and to a length corresponding exactly with
those of McCormick's adjustable iron bar, and, like the latter, it
is gradually curved to a vertical elevation intended to be great
enough to separate and raise up the wheat designed to be
immediately severed by the cutters from that reserved for farther
action of the machine. The only differences between this fixture
and the adjustable bar of McCormick (and they are merely pretended
and deceptive)
Page 61 U. S. 412
are these: that the former, instead of being of iron, is made of
wood; that instead of being movable or adjustable, it is
stationary; that it is broader on its lateral surface than is that
of the iron portion of McCormick's divider, and on that lateral
surface is somewhat curved. But these differences, correctly
apprehended, are mere disguises, and were indispensable to shelter
the possession of property evidently pirated from the rightful
owner. Had the appellees openly taken McCormick's iron instrument,
adjusted it so that it could be graduated in practice to the
quality or height of the grain in which the machine was to operate,
and placed it at an angle suited to the conducting of the grain
within the action of the reel and cutters, there would in so bold a
piracy have been left no ground -- no pretext even -- for contest
or cavil. Hence the effort at distinctions or differences attempted
in the case. To my mind, it seems impossible not to perceive that
they are entirely unfounded, and cannot for one instant conceal
these truths,
viz., that the instrument or structure
called a divider, introduced and practiced by the appellees, is in
theory or principle, in
manner of its operation,
in its
effects or
results, and it may almost be
said in its
minute constituent portions and formation,
identical with the instrument invented by and patented to the
appellant, and therefore an infringement of the rights guaranteed
to him by the government.
Entertaining this opinion, I must dissent from the decision of
the court in this cause, and declare it as my opinion that the
decree of the circuit court should be reversed and this cause
remanded with instructions to reinstate the injunction formerly
awarded by the circuit court and to direct an account between the
parties. The only legitimate inquiry for the Court is this: whether
the improvement of McCormick called a "divider" and the instrument
claimed and put in operation by Manny are essentially the same or
are essentially or substantially different. All that has been said
-- and a great deal has been said -- about the comparative
superiority or inferiority of inventions or improvements previous
to those patented to McCormick is wholly irrelevant and out of this
cause, and is calculated only to confound and to divert the
attention from the only proper subject of investigation here, which
is the rightfulness of the claims advanced by the appellant and
appellees in this cause, relatively to themselves, and to no
others.
