County of Middlesex, Engineer & Patent Agent, for the Invention of
"IMPROVEMENTS IN STAMPING PRESSES."-A communication from abroad
by Adolphe Charies Guillemot, of Paris, in the Empire of France,
Mechanician.
Sealed the 19th September 1861, and dated the 2nd April 1861.
PROVISIONAL SPECIFICATION left by the said William Clark at the
Office of the Commissioners of Patents, with his Petition, on the 2nd
April 1861.
I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer & Patent Agent, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN STAMPING PRESSES," to be as follows:-
This Invention relates, to a new arrangement of stamping press, " whereby
the letters are supplied with ink during the action of stamping, instead of
baving recourse to a separate pad, as heretofore. This improved press is so
constructed that all the parts in contact with the ink are prevented from
soiling either the objects to be stamped, or adjoining parts. The arangement
of the feet assists in this, as also in regulating the exact position of the object
to be stamped, while at same time the part which forms the pad prevents any
foreign matter getting in between the letters in relief; a wood lining is placed

page_text: in the interior of a cylinder, in which is a spiral spring, to obviate the noise
caused by the metal spring rubbing against the cylinder; the inking roller is
also surrounded by a metal plate, to prevent soiling of the objects to be
stamped. An ink reservoir is placed above the roller, which supplies it with
ink automatically when it passes underneath the reservoir. This improved
press is constructed without gearing of any kind, thereby greatly diminishing
its cost.
In the annexed Drawing is represented an arrangement of my improved
press; Fig. 1 being a longitudinal vertical section; Fig. 2 a side elevation in
position for stamping; and Fig. 3 a front view of the press when at rest;
while Figs 4 & 5 show separate views of the ink reservoir placed above the
inking roller. The same letters of reference indicate corresponding parts in
all the Figures.
a, tube sliding in socket 6 attached to plate c; d, piston connected to
socket. by a pin e, which slides in grooves in tube a, to allow it to move
freely; a spring placed in tube a bears at one end on piston d, and at the
other on the under part of knob g, which it raises; h, feet of the press, for
facilitating its action, as above mentioned; at the lower end of tube a is fixed
a piece i, to which is attached the surface in relief, or case of type; j, roller
covered with wool, pivotted in extensions of the part i; k, part forming a pad,
furnished with a surface of cloth; it turns on pivots fixed to the feet h, and
when not in uso rests on the surface in relief; the sides of this piece have
slots, in which the pivots of the roller j take; ', metal plate placed above the
inking rollersj; m, wood lining of tube a in contact with spiral spring f;
n, ink reservoir fixed to the two plates c, c, of the press, for inking auto-
matically the roller j; o, cover of the reservoir. The whole being mounted
as described and represented, the apparatus is placed on the object to be
stamped, when by bearing on the knob g the part i descends vertically,
carrying with it the relief or stamp, properly so called, which stamps the
impression at the same time that the pivots of roller j slide in the grooves of
part k, and cause it to turn on its axis 7, and thus allow a passage for the die.
During this movement the inking roller is caused, by reason of the form of
the groove of, to deposit a coating of thick ink on the woollen surface of
part in which it is imbibed. After the impression is made, the knob
k
g is
released from the pressure of the hand, and then rises by the action of the
spring, while the roller in rising deposits another coating of ink on the surface
of the part k, at the same time coming in contact with the relief surface.

filed by the said William Clark in the Great Seal Patent Office on the
2nd October 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CLARK, of 53, Chancery Lane, in the County of Middlesex, Engineer and
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of April, in the year of our Lord One
thousand eight hundred and sixty-one, in the twenty-fourth year of ller
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Clark, Her special licence that I, the said William Clark, my
executors, administrators, and assigns, or such others as I, the said William
Clark, my executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN STAMPING PRESSES," a
communication to me from abroad by Adolphe Charles Guillemot, of Paris,
in the Empire of France, Mechanician, upon the condition (amongst others).
that I, the said William Clark, my executors, or administrators, by an instru-.
ment in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and im
mediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Clark, do hereby declare thio
nature of the said Invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following..
statement, reference being had to the Sheet of Drawings hereunto annexed, and.
to the letters and figures marked thereon (that is to say)
This Invention relates to an improved stamping press, the distinctive
feature of which consists in its inking the letters or designs in relief simulta-
neously with the action of stamping, by a self-acting arrangement of apparatus.
This improved press is constructed in such manner that all the parts which
are in contact with the ink are prevented from smearing the objects to lo
stamped, or adjacent objects. The press is furnished with feet, which, while
forming a support, also serve for adjusting the precise part on which the
stamping action is to be applied. This press has the further advantage of

page_text: great smprenty res
any kind.
: The annexed Drawings represent several arrangements of this improved
press, which differ from each other only in the details of construction, being
all on the same principle of self-inking during the stamping action.
DESCRIPTION OF DRAWINGS.
Fig. 1 shows a central vertical section of one form of inking and stamping
press, and Fig. 2 a side elevation of the same in position for stamping;
Fig. 3 shows a central vertical section of another arrangement of press, while
Figs. 4 & 5 show details herein-after described; Figs. 6, 7, 8, & 9. represent
elevations of modified arrangements of the press, the front leg or support being
removed in order to more clearly show the various parts.
In Figs. 1 & 2, representing one form of press, the same letters of reference
indicate like parts. a, tube terminated at the upper part by a handle or
knob b, and having at the lower part the die on which is produced the letters,
designs, or ornaments to be applied; c, fixed socket in which the tube a slides;
d, piston placed in the interior of tube a, held in position by a pin e fixed in
socket c;f, spiral spring acting the one part on piston d, and the other on the
lower part of handle b, so as to constantly raise the die, as seen in Fig. 1,
when the handle 6' has ceased to be acted on; 9, grooves made, in tube a, in
which the pin e slides; h, feet for supporting the press; i, extension pieces cast
on legs h, to which the socket c is attached; j, box fixed at the lower part of
stem a, in which are placed the letters or designs to be impressed; k, movable
piece turning on an axis o, acting as an inking pad and pressing on the surface
in relief. The under face of this part which is in contact with the type is
furnished with a woollen pad 1, which is charged with ink cach time by means
of an inking roller m.. n, grooves made in part k in which the pivots p of
roller m travel. The roller m is fixed on the case of type or other composition
jin such manner that when the press is placed on its feet and the knob b
operated upon, the die will be lowered upon the paper or other matérial
placed between the feet of the press at the same time that the roller turns on
its axis, and inks the pad 7 on part k in such manner that when the die is
again raised by the action of spring f, the pad will come in contact with
the engraved surface and supply it with ink.
Fig. 3 represents an improved arrangement of the above press, which
differs from it 1st, by the application of a wood lining q placed in the interior
of tube a, a, to prevent the noise occasioned by the metal spring when working
up and down therein; 2ndly, of a small plater placed above the inking roller

page_text: and enclosing it, so as to prevent any soiling of the objects to which the
stamping is to be applied.
Figs. 4 & 5 represent a front elevation and section of an ink reservoir s,
placed above the roller, and inking it in a self-acting manner when it passes
under said reservoir.
Figs. 6 & 7 represent another arrangement of inking and stamping press,
in which the inner spring f for raising the die is dispensed with and replaced
by a spiral spring t surrounding axis o, which acts in the same manner as f;
the pad is also dispensed with and replaced by an inking roller u, which is
caused to pass over the letters or other designs in relief, while the roller m
serves as an ink reservoir. In Fig. 8 the case of type j is vertical, and is
carried by a part v turning on an axis x fixed at the lower end of stem a.
This metal part is guided on the other hand in a groove y, on pivots =, so
that when pressure is exerted on knob 6 the part bearing the engraved
surface will be caused to assume the position represented in dotted lines in the
Drawing. During this movement the plate ; bearing the engraved surface
comes in contact with the inking roller u, which turns on its axis and on
point 1 to allow of the free motion of plate j, and so as to constantly act on it
by its weight. In Fig. 9 the inking roller is held against the letters or
designs by the combined effect of two series of grooves 2 & 3, in which the
pivots of the inking roller are guided in such manner that when pressure is
exerted on the handle b, the roller u, being guided by grooves 2 & 3, is caused
to pass over the whole type or engraved surface to deposit the necessary
amount of ink thereon for obtaining the impression desired.
Having described the nature of the Invention, & the manner of performing
the same, I declare that what I claim as the Invention to be protected by the
herein-before in part recited Letters Patent is :-
First, the arrangements of presses herein-before described, the distinctive
feature of all of which is their capability of self-inking, also in the press
represented at Figs. 1 & 2 of dispensing with all gearing of any kind.
Secondly, in the press shown at Fig. 3 I claim the application of the wood
lining to the tube, and also the small plate above the inking roller.
Thirdly, in the press represented at Figs. 6 & 7 I claim the application of
the spiral spring on axis o, instead of the spiral spring in the tube a, as also
the roller for passing over the engraved surface.
Fourthly, I claim the stamping press represented at Fig. 8, in which the
type or composition is placed in a vertical position, which is inked by the
roller while turning on its axis.
Fifthly, I claim the application in the press represented at Fig. 9 of an

page_text: וי
inking roller, which is caused to pass over the engraved surface by the
combined series of guide grooves, herein-before described.
I also claim the right of applying the ink reservoir represented at Figs. 4 & 5
of the Drawings annexed to all kinds of stamping presses.
In witness whereof, I, the said William Clark, have hereunto set my
hand and seal, this First day of October, in the year of our Lord One
thousand eight hundred & sixty-one.
