PROVISIONAL SPECIFICATION left by the said John Pinches at the
Office of the Commissioners of Patents, with his Petition, on the 26th
October 1855.
I, JOHN PINCHES, of Oxendon Street, Haymarket, in the County of Middlesex,
Die Sinker, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF DIES OR STAMPS FOR MARKING PAPERS, LINEN, OR OTHER
SUBSTANCES," to be as follows:-
These improvements are designed for the purpose of facilitating and
rendering more efficient than heretofore the operation of stamping or marking.
by hand, with dies or stamps, papers, linen, or other substances. The mode
heretofore commonly practised of performing such operation has been by the
use of a stamp or die placed in a handle, said stamp or die being first pressed
upon a "dabber" or "pad" containing the desired colouring matter, and
afterwards the material to be marked therewith, by exerting pressure upon the
said stamp. Now, whereas such mode is uncertain in its action in consequence

page_text: of the uncertainty of an uniform pressure being exerted all over the stamp or
die, it follows, therefore, that the impress therefrom will be imperfect; and
the object of this Invention is to remedy this objection, by placing the stamp
or die in a case or holder of the following construction:-The stem of the
handle into which the stamp or die is screwed or otherwise held is formed
cylindrical, and fits.in cylindrical-shaped holes formed in a circular case of
wood or other suitable material, into the top of which a cap is screwed, to
admit of a helical tempered steel spring being placed in said case, which is
formed large enough to receive such said spring; the bottom of the above
case is formed considerably larger in diameter than the stamp or die, and has
a "dabber" or "pad" fitting thereinto. There is a collar upon the upper
part of the steni of the handle of the stamp or die, which serves two purposes,
namely, to condense the spring by pressing upon the handle, and also to raise
the stamp or die when the pressure is removed therefrom. In using a stamp
or die thus constructed, the operator first presses the stamp or die upon
the dabber" or "pad; he then removes the same, and places the bottom
edge of the case upon the material or substance to be marked; 'by which he
gets an uniform bearing of such part, and; holding the said 'case with one hand,
with the other he depresses the stamp or die, which is thus uniformly pressed
upon the material, and the marking thereof effected comparatively perfect.....

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of October, in the year of our

Pinches, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter

SUBSTANCES upon the condition (amongst others) that. I, the said John Pinches,
my executors or administrators, by an instrument in writing under mý, 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 per-
formed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said John Pinches, do hereby declare
the 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 thereof, that is to say-

...::
My improvements are designed for the purpose of facilitating and rendering
more efficient than heretofore the operation of stamping: or, marking.by hand,
with dies or stamps, papers, linen, or other substances...:..
The mode heretofore commonly practised of performing such operation has
been by the use of a stamp or die placed in a handle, said, stamp or die
being first pressed upon a "dabber" or "pad" containing the desired coloring
matter, and afterwards upon the material to be marked therewith, by exerting
pressure upon the said stamp. Now, whereas such mode of operating is defec
tive in its action, arising from the uncertainty of an uniform pressure being
exerted over the entire surface of the stamp or..die, it follows, therefore, that
the impress therefrom will be imperfect; and the object of my said Invention
is to remedy the above objection, by placing the stamp or die in a case or
holder, so constructed as to enable the operation of marking to be effected by
percussive force instead of steady pressure, as heretofore, practised, thereby
facilitating the operation and rendering it more efficient. The following is the
construction of the above-mentioned case or holder-The stem of the handle
into which the stamp or die is screwed or otherwise. held. is formed cylindrical,
and fits into a corresponding shaped hole formed in a circular piece, of wood
or other suitable material. The aforesaid stem is formed hollow, and has a
helical steel spring placed therein, for forcing up the handle and die when
pressure is removed, therefrom. The bottom of the aforesaid..case or holder
fits into a pad box containing the necessary marking,ink.... In using a die.or
stamp of the above construction, the operator first presses. the, die or stamp
upon
the "pad" he then removes the "pad box," and places the bottom edge
of the case or holder upon the material or substance to be marked, by which
he gets an uniform bearing of such part, and thus presents, the die or stamp

page_text: sharp blow, which is thus uniformly pressed upon the material, and the
marking thereof effected comparatively perfect..
.
In order to explain my said Invention as completely as possible, I now pro-
ceed to describe the best means I am acquainted with for. carrying the same
into. practical effect, reference being had to the illustrative Drawing hereunto
annexed, and to the numeral figures and letters of reference marked thereon.
respectively, as follows:-
DESCRIPTION OF THE DRAWING.
Figure 1 is an outside elevation of one of my improved dies or stamps,
exhibiting the "pad box" (herein-after referred to) in section; Figure 2 is a
transverse and vertical section, taken through the line A, B, at Figure 1, the
"pad box" being omitted; Figure 3 is a top plan view of the "pad box;'
Figures 4, 5, 6, detached portions, herein-after referred to. At each of the
foregoing Figures, I employ similars letters of reference to denote correspond-
ing parts, in so far as such parts appear or can be seen at each of the said
Figures respectively.
A, A, is a piece of wood, the lower part of which has a recess formed therein,
äs at B, Figure 2; there is a hole formed through the centre of the piece A, into
which a metal bush C is tightly fitted. D is a metal tube, in which are formed
slots x, x, (shewn also at Figure 5); E is a pin, passed through the slots a, a,
and holes in the case A, to receive said pin; G. is a helical tempered steel
spring, the lower part of which, when placed in the tube D, is arrested by the
pin E; the upper part of the said tube has a piece of wood d fitted thereinto,
and held by the pin e. His a metal stamp or die (shewn detached at
Figure 6), the part H of which is engraved, as desired, and the upper part i
fits tightly into the lower end of the tube D. In order to ascertain readily the
position of the top of the engraving on the stamp or die, an arrow is engraved
on the top of the handle, as at Figure 4, care being taken in adjusting the
stamp or die within the aforesaid tube, to keep the top of the engraving in a
line with and pointing towards the point of the said arrow; to ensure this, a
short pin y may be let into the part of the stamp or die H, as at Figure 2;
said pin taking into a notch in the tube D. I is the "pad box," the pad k of
which is of the ordinary kind. In using the above stamp or die for marking
papers, &c., it is desirable to place the material to be marked on a thick piece
of cloth, or other similar substance.
Having now described the nature and object of "my said Invention of

page_text: "improvements in the construction of dies or stamps for marking papers, linen,
and other substances," together with the best means I am acquainted with for
carrying the same into practical effect, I would remark in conclusion that what
I claim as my Invention is, the combining of the spring G with the case A
and stamp H, in the manner and for the purpose above stated, substantially as
set forth and described in this my said Specification.
In witness whereof, I, the said John Pinches, have hereunto set my
hand and seal, this Twenty-fourth day of April, in the year of our
Lord One thousand eight hundred and fifty-six.
