1. Whether claim 3 of letters patent No. 67,048, granted to
Joseph L. Hall, July 23, 1867, for an "improvement in connecting
doors and casings of safes," namely
"3. The conical or tapering arbors, 1, in combination with two
or more plates of metal, in the doors and casings of safes and
other secure receptacles, the arbors being secured in place in the
plates by keys, 2, or in other substantial manner,"
claims arbors which are tapped into two or more plates, or
whether it excludes, as a part of it, screw threads cut on the
arbors, is immaterial in the present case because, under the former
view, the defendants are not shown to have used arbors with screw
threads on any part of the arbor within the plates, and, under the
latter view, the claim is invalid.
2. The whole invention is described in letters patent No.
30,140, granted to Hall, Sept. 25, 1800, for an "improvement in
locks," and a cored conical bolt with a screw thread on it is shown
in those letters. A solid conical bolt having existed, adding the
screw thread to it is not an invention.
3. Solid conical bolts without screw threads having been used in
two safes made and sold by the inventor more than two years before
his letters were applied for, the invention covered by claim 3 was
in public use and on sale, with his consent and allowance, so as to
make the claim invalid under secs. 7 and 15 of the Act of July 4,
1836, c. 357, and sec. 7 of the Act of March 3, 1839, c. 88.
Appeal from the Circuit Court of the United States for the
Southern District of Ohio.
The case is fully stated in the opinion of the court.
MR. JUSTICE BLATCHFORD delivered the opinion of the Court.
This suit is brought on letters patent No. 67,046, granted to
Joseph L. Hall, the appellant, July 23, 1867, for an "improvement
in connecting doors and casings of safes." The only claim alleged
to have been infringed is claim 3, which is in these words:
"3. The concial or tapering arbors, 1, in combination with two
or more plates of metal, in the doors and casings of safes and
other secure receptacles, the arbors being secured in place in the
plates by keys, 2, or in other substantial manner."
In regard to what is embraced in this claim the
Page 107 U. S. 91
specification says:
"The nature of this invention consists in . . . securing a
series of plates forming a casing or door of the safe by means of
conical or tapering arbors, which, being tapped in from the outside
of the door or casing, and keyed upon the inside, present serious
obstacles to the removal of successive plates forming the body of
the safe. Figure 1 represents a perspective view of a safe
embodying my invention. Figure 2 is a horizontal section of part of
the same. Figure 3 is a detail view, in cross-section, of the door
of the safe, showing the shape of, and manner of securing, an
arbor. The most approved manner of securing together the numerous
plates forming the casings and doors of safes is by means of screws
tapped in from one series of pairs or triplets of plates from the
inside presenting no rivet heads upon the outside surface of the
safes. . . . In the doors of safes the outer plate D is secured to
the plate E, F, by screws
b, countersunk in the plate, F.
. . . The fourth plate, I, has about the same area as the plate E.
It is secured to the plate, F, by screws
e, which pass
through the inner plate K, in which they are countersunk. . . . In
order to still further secure together the plates forming the door
of the safe I use a conical arbor 1 or a number, if necessary; they
are introduced in openings through the series of plates, being
tapped into the two innermost of all the plates, and keyed in
position. A smooth surface in the plane of the outer face of the
door is presented, giving no means of removing the arbors I, even
should the key 2 be removed. . . . Since the doors of safes are
more exposed than any other part of them, it is necessary to embody
in their construction such devices, which in themselves are the
simplest, as shall effectually bar forcible entrance to the safes.
The introduction of arbors for the purpose of more effectually
binding in one compact mass the series of alternate iron and steel
plates in the doors or bodies of safes will very much protract the
labors of the burglar; indeed, it will be necessary, in order to
remove one sheet in succession, to cut out the arbors, which are
made of the hardest steel. The arbors may be tapped through the
entire series of plates, and the inner end rivet-headed instead of
keyed, as shown in the drawing, or the inner plate, as well as
other in the series of plates, may be put together in sections,
and, fitting into notches in the arbor
Page 107 U. S. 92
or arbors, secure them in position. In this latter construction,
the arbors need not be conical, but may have any cross-section,
tapering longitudinally."
When the specification says that the conical arbors are "tapped
in from the outside," it means that screw threads are cut on them
and take into screw threads in the body, and that the arbors are
screwed in and have their smaller end toward the inside. The
drawing, figure 3, shows this, there being five plates, and the
arbor being in position, and tapering from the outside to the
inside, the larger end being toward the outside, and a screw thread
being cut on the arbor for the distance of the thickness of the two
innermost plates, and the arbor extending through the five plates,
from the outer surface of all to the inner surface of all, and a
key extending from the inside lengthwise of the arbor, the distance
of the length of the screw thread. The arbors, the specification
says, "may be tapped through the entire series of plates" -- that
is, the entire length of the arbor may have a screw thread cut on
it -- and the inner end may be rivet-headed, that is, headed down
into a rivet instead of being keyed. A peculiarity of the conical
arbors is stated in the specification to be that they are tapped in
"from the outside," and "keyed upon the inside," in
contradistinction to the then existing most approved method of
having screws with conical heads, the heads being countersunk in
one of the plates, and the cone shape of the heads holding the
screws so as to make it unnecessary to rivet them on the outside of
the safe, the screws not going through all the plates, the head of
the screw being toward the inside of the safe and the other end of
it not projecting beyond the outside. Whether claim 3, in claiming
"the conical or tapering arbors, 1, in combination," etc., is to be
held, in view of the description in the text of the specification,
and of the drawing, figure 3, to necessarily claim arbors which are
tapped into two or more plates, or whether that claim excludes as a
part of it screw threads cut on the arbors, is not material to this
case. If the former, the appellees are not shown to have used
arbors with screw threads on any part of the arbor that is within
the plates. If the latter, then, infringement being shown, we are
satisfied that claim 3 cannot be sustained. The contention of the
appellant is that the
Page 107 U. S. 93
invention covered by that claim requires only a conical hole,
conical through the entire series of plates to be secured, and a
conical bolt corresponding thereto, and secured in place in the
plates by a key, or in any other substantial manner.
A patent was issued to the appellant September 25, 1860, for an
"improvement in locks." The specification of that patent says:
"Resting upon the front plate B of the lock, as shown in figure
4, are seen two conical blocks I I', a plan of which is represented
in Figure 11. These are precisely alike in their construction, and
they are adapted to the two stems, G and H, as will appear. They
are of a length corresponding with the thickness of the door M, to
which the lock is applied, so that, when introduced into
appropriate apertures in the door, their outer faces will be flush
with the outer face of the door, and their inner faces flush with
the inner face of the door, and against the front face of the lock,
when the same is properly fixed upon the door. The blocks I I'
enter their apertures in the door by a screw thread, and they are
held from turning therein, so as to return outwardly, by an
ordinary key driven into a key-seat drilled from the inside of the
door before the lock is applied to its place. . . . The conical
blocks are cored or drilled out in a peculiar manner to receive the
two-part revolving arbor, as shown, the part,
p
(
p'), entering the narrow end of the conical blocks, being
of a cylindrical form, and the part
q (
q'),
entering the large end of the conical blocks, being of a conical
form. These revolving arbors turn the stems G and H, and thus the
tumblers are adjusted and the bolt of the lock is thrown. The
drawing of the patent shows the conical blocks I I', as passing
entirely through the door, the larger end of the cone on the
outside, and each end flush with its proper face. These conical
blocks were screw threaded on their surface in the door, and were
keyed from the inside. They were cored to admit the revolving
arbors, but their bodies operated in all respects like the conical
arbors of the patent sued on."
In 1868, John Farrell and Jacob Weimar applied for a patent for
the same thing covered by claim 3 of the patent sued on, and the
Patent Office declared an interference between their application
and that patent. The appellant was examined as a witness on his own
behalf, in October, 1868, in that interference,
Page 107 U. S. 94
and testified as follows:
"
3d Int. State what knowledge you have had, in
manufacturing safes, of the use of a series of plates united by
conical bolts made drill-proof, and when and where you first had
knowledge of their use."
"
Ans. The first was in the year 1858 or 1859. I came
across one John P. Lord's lock, which was said to be a combination,
no-key-hole bank lock. I negotiated with the parties representing
it, to try and introduce it and manufacture it. I then began to
examine into it more particularly, and found that the knob or dial
projecting through the door seemed to be very insecure in its
construction. I set myself about so as to invent some better way of
securing the protection to the lock and also the plates of the
doors. I then invented a double and single conical-shaped arbor or
plug, made drill-proof, composed of wrought iron and steel welded
together, the design of which was to fully protect the lock against
sledge hammers or other tools for driving the plug or plugs in, or
from being drilled into, they being hardened. The further design of
the said drill proof plugs or arbors was to secure together a
series of plates of wrought iron and steel, or other suitable
metal, whereby they could not be separated or pulled apart, more
firmly binding them together than had been our former method of
making safes, or joining together such series of plates. Sometime
after, during the year 1859 or 1860, the exact period of time I
cannot remember fully, we made burglar proof safes of a series of
plates composed of iron and steel joined together, in which we had
used more of the conical drill proof bolts or arbors than we had
formerly been in the habit of doing, for the express purpose of
more securely fastening the plates together. We made them in the
City of Cincinnati, in our factory, which was situated about the
middle of the square bounded by Columbia, Sycamore, Front, and Main
Streets. We have also used them to a very considerable extent since
that time, in our factory situated at the southwest corner of Plum
and Pearl Streets. I secured a patent for my double conical drill
proof arbor in the year 1860. My design of that was to secure full
protection to combination no key hole bank locks. My single arbor I
don't think I made any claim on at that time, but used it for the
express purpose of binding the series of plates together. This
Page 107 U. S. 95
was also a conical drill proof bolt, made of iron and steel. Our
modes of fastening the above described arbors were in different
ways. Some we made conical at the smaller end were made soft, so
that we could rivet them down into a countersunk plate; others we
cut a thread upon at the small end of the arbor or drill proof
bolt, which was done, and, when fitted up, the conical shaped arbor
or bolt was tempered; others were made with a thread cut upon the
end of them, designed for a nut, which was designed to be used on
the smaller end of them to fasten them more securely, so that they
could not be withdrawn from the outside. The conical shaped arbor,
with the thread cut upon the arbor, was designed to be screwed into
the inner plate of a series of plates, and then a key seat cut in
each of the threads of the plate and of the arbor, so that keys
could be driven in to prevent their being unscrewed and withdrawn
from the outside, thereby making them secure against the drill or
the use of the sledge hammer or other tools for forcing them in,
being of a conical shape, or from removing any of the series of
plates through which they passed."
It is apparent from this testimony that the appellant regarded
the double conical shaped arbor or plug, that is, the cored conical
block, and the single conical shaped arbor or plug, as being the
same invention. He was endeavoring to carry back to 1858 or 1859
the invention covered by claim 3 of his patent of 1867. The only
difference he makes between the double and the single arbor is that
the former had a core removed from it. The latter was solid. Both,
he says, were drill proof, and had the same further design or
object, namely, to secure together a series of plates in safes. He
also says that in 1859 or 1860, he made burglar proof safes of a
series of plates composed of iron and steel joined together, using
in them these single conical bolts or arbors, for the express
purpose of more securely fastening the plates together. He then
describes the cutting of a thread upon the arbor and one of the
plates to screw the arbor into the inner plate, and cutting a key
seat in the two threads, and putting in a key to prevent the arbor
from being unscrewed from the outside. All this describes exactly
what is covered by claim 3 of the patent sued on.
In his testimony in the present suit the appellant states
that
Page 107 U. S. 96
he made three safes between 1859 and 1864 which were burglar
proof, and had conical bolts for fastening together the different
plates of metal. One of them had the double conical bolt and no
single bolt, and was sold to a firm in Dayton, Ohio. One was made
in 1858 or 1859, to be exhibited at a fair in Ohio, and was sold to
a banker in Lafayette, Indiana. It had the single drill proof
conical arbors in the doors. The third one was made to be exhibited
at a fair held in 1860, and was sold to the Treasurer of Loraine
County, Ohio. It had a few of the single conical arbors. It does
not distinctly appear that the single conical bolts in the
Lafayette and Loraine County safes had screw threads cut on them,
but the appellant testifies in this case that the double arbor of
his patent of 1860 had a screw thread cut upon it running through
one or more of the inner plates, for the purpose of holding it. It
clearly appears, from the testimony of the appellant himself, that
the idea of making a claim to the invention covered by claim 3 of
the patent sued on arose from the introduction into safes, in 1866
or early in 1867, of plates of steel and iron welded together. This
enabled the value of the screw threaded conical bolt to be more
fully developed, because the screw thread could be made more
effective the whole length of the bolt. But the whole invention
existed in the bolt of the patent of 1860. There was no invention
in adding to the solid conical bolt the screw thread of the cored
conical bolt.
Moreover, the use and sale of the solid conical bolts in the
Lafayette and Loraine County safes, even though those bolts had no
screw threads on them, constituted a use and sale of the invention
covered by claim 3 of the patent in suit. The application for that
patent was made in March, 1867, and the patent was granted under
the provisions of the Act of July 4, 1836, c. 357, and of the Act
of March 3, 1839, c. 88. Within the meaning of secs. 7 and 15 of
the act of 1836, as modified by sec. 7 of the act of 1839, the
invention covered by claim 3 of the patent in suit was in use and
on sale more than two years before the appellant applied for that
patent, and such use and sale were, also, with the consent and
allowance of the appellant, and the use was a public use. It is
contended that the safes were experimental, and that the use was a
use for
Page 107 U. S. 97
experiment. But we are of opinion that this was not so, and that
the case falls within the principle laid down by this Court in
Coffin v.
Ogden, 18 Wall. 120. The invention was complete in
those safes. It was capable of producing the results sought to be
accomplished, though not as thoroughly as with the use of welded
steel and iron plates. The construction and arrangement and purpose
and mode of operation and use of the bolts in the safes were
necessarily known to the workmen who put them in. They were, it is
true, hidden from view after the safes were completed, and it
required a destruction of the safe to bring them into view. But
this was no concealment of them or use of them in secret. They had
no more concealment than was inseparable from any legitimate use of
them. As to the use's being experimental, it is not shown that any
attempt was made to see if the plates of the safes could be
stripped off, and thus to prove whether or not the conical bolts
were efficient. The safes were sold, and apparently no experiment
and no experimental use were thought to be necessary. The idea of a
use for experiment was an afterthought. An invention of the kind
might be in use and no burglarious attempt be ever made to enter
the safe, and it might be said that the use of the invention was
always experimental until the burglarious attempt should be made,
and so the use would never be other than experimental. But it is
apparent that there was no experimental use in this case, either
intended or actual. The foregoing views, which are controlling to
show that claim 3 of the patent in suit cannot be sustained, are in
accordance with those announced by this Court in
Egbert v.
Lippmann, 104 U. S. 333.
Decree affirmed.
