IMPROVE- MENTS IN PRESSES FOR EMBOSSING, STAMPING, PERFORATING, OR PUNCHING, DIE AND COUNTERPART
Year: 1872

page_text: LETTERS PATENT to John Pinches, of 27, Oxenden Street, in the
County of Middlesex, Die Sinker, for the Invention of "-IMPROVE-
MENTS IN PRESSES FOR EMBOSSING, STAMPING, PERFORATING, OR PUNCHING,
PROVISIONAL SPECIFICATION left by the said John Pinches at the
Office of the Commissioners of Patents, with bis Petition, on the
13th August 1872.
I, 'JOHN PINCHES, of 27, Oxenden Street, in the County of Middlesex,
Die Sinker, do hereby declare the nature of tho said Invention for "In-
*PROVEMENTS IN PRESSES FOR EMBOSSING, STAMPING, PERFORATING, OR PUNCHING,
AND AN IMPROVED DIE AND COUNTERPART FOR EMBOSSING AND PERFORATING," to be
as follows:-
:-
-
The first part of my Invention relates to a mode of imparting the
requisite-up-and-down- movements to the plunger of the press, and
consists in the construction and employment of a cam and a crank
arranged and acting as about to be described: Upon the top of the
plunger, I.cast or fix a block in which a cam of peculiar shape is formed,
and in this cam works a crank on the axle of a band wheel, which axle
:

page_text: passes through the cheeks of the press. The shape of the cam is such
that the crank in its upward back movement after the blow has been
struck bears underneath a portion of the cam, and gradually raises it
together with the plunger and dic, until both the crank and the cam
plunger and dic are in their highest position. Then the crank runs
underneath a portion of the cam which is a segment of the circle in
which the crank travels, so that the crank does not in this part of its
movement act upon the cam. In the reverse or forward movement the
crank first returns underneath this segment of a circle, and therefore
does not act upon the cam until it begins to descend the side of the
same. By this means an increased revolution of the wheel is obtained
to give impctus to the blow, which is produced smartly by the crank
bearing upon the last portion of the cam, which has only a slight
inclination from the horizontal, thereby effecting the embossing, stamp-
ing, perforating, or punching of the paper or other material, which is
placed between the die and the counterpart.
The second part of my Invention consists in constructing the dic
and the counterpart of embossing presses so that they will both
emboss and perforate the paper or other material at one operation.
This may be effected by arranging in a circle or in any other required
design or pattern on the counterpart a series of pins or cylindrical
protuberances, which are of greater elevation than the counterpart,
and by forming in the face of the die a corresponding series of vertical
holes which extend into a groove or grooves or channels in the back of
the die. Thus when the dic is forced down upon the paper or other a
material on the counterpart, the design engraved on the die becomes
embossed upon the said material while the pins pass through the
material and form a series of perforations therein, the small portions
of the material punched out passing through the holes in the dic
into the groove or grooves or channels at the back. This part of my
Invention for constructing the dic and counterpart so as to emboss and
perforate at one operation will apply to the preparation of documents
of various kinds, in which both embossing and perforating are desirable,
and more particularly to the production of ballot or voting papers which
require to have a special stamp visible both on the face and back thereof.
The die may be carried by the plunger, and the counterpart be secured
to the bed of the press, or vice versa.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Pinches in the Great Seal Patent Office on
the 13th February 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
PINCHES, of 27, Oxendon Street, in the County of Middlesex, Dic
Sinker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of August, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said John Pinches, Her special licence that I, the
said John Pinches, my executors, administrators, and assigns, or such
others as I, the said John Pinches, 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 PRESSES FOR EMBOSSING,
STAMPING, PERFORATING, OR PUNCHING, AND AN IMPROVED DIE AND COUNTERPART
FOR EMBOSSING AND PERFORATING," upon the condition (amongst others) that I,
the said John Pinches, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and scals, 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 Scal 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 my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, reference being had to the accompanying
Drawings, that is to say :-
The first part of my Invention relates to a mode of imparting the
requisite up and down movements to the plunger of the press, and
consists in the construction and employment of a cam and a crank
arranged and acting as about to be described. Upon the top of the
plunger I cast or fix a block in which a cam of peculiar shape is

page_text: formed, and in this cam works a crank on the axle of a hand wheel,
which axle passes through the checks of the press. The shape of the
cam is such that the crank in its upward back movement, after the
blow has been struck, bears underneath a portion of the cam and
gradually raises it together with the plunger and die until both the
crank and the cam plunger and die are in their highest position.
Then the crank runs underneath a portion of the cam which is a
segment of the circle in which the crank travels, so that the crank
does not in this part of its movement act upon tho cam. In the
reverse or forward movement the crank first returns underneath this
segment of a circle, and therefore does not act upon the cam until
it begins to descend the side of the same. By this means an increased
revolution of the wheel is obtained to give impetus to the blow, which
is produced smartly by the crank bearing upon the last portion of the
cam, which has only a slight inclination from the horizontal, thereby 1
effecting the embossing, stamping, perforating, or punching of the
paper or other material, which is placed between the dic and the
counterpart.
Figure 1 of the accompanying Drawings is a side view of a press
constructed according to this part of my Invention, one of the checks 2
of the press being shewn as removed; Figure 2 is a detached side view
of the cam block, and of a portion of the plunger; Figure 3 is a plan of
the axle of the hand wheel.
A represents the cheeks of the press; B, the hand wheel; C, the axle
of the same which passes through the said checks; D is the crank on 2
the axle C; E is the plunger; and F the cam block cast on the top
of the plunger. After the blow has been struck the crank is at the
point 1, see Figure 2. In the upward back movement it bears under-
neath the portion of the cam from 2 to 3, and gradually raises it
together with the plunger and dic until the crank and cam plunger 3
and die are in their highest position. Then the crank runs underneath
the cam from 3 to 4, this portion being a segment of the circle in which
the cam travels, so that, as before explained, the crank does not in this
part of its movement act upon the cam. In the reverse or forward
movement the cam first returns from 4 to 3, and does not act upon the 3
cam until it begins to descend the side from 3 to 2, so that an increased
revolution of the wheel B is obtained to give impetus to the blow,
which is produced smartly by the crank bearing upon the portion

page_text: from 2 to 1, which it will be seen has only a slight inclination from
the horizontal. Thus, as has already been stated, the embossing, stamp-
ing, perforating, or punching is effected.
The second part of my Invention consists in constructing the dic
and the counterpart of embossing presses so that they will both
emboss and perforate the paper or other material at one operation.
This may be effected by arranging in a circle or in any other required
design or pattern on the counterpart a series of pins or cylindrical
protuberances which are of greater elevation than the counterpart, and
by forming in the face of the die a corresponding series of vertical
holes which extend into a groove or grooves or channels in the back
of the die. This part of my Invention is represented in Figures 4, 5,
6, and 7; Figure 4 being a plan of the under side, and Figure 5, a
vertical section of the dic, and Figure 6 a plan, and Figure 7 a vertical
section of the counterpart. a, a, Figures 6 and 7, are a series of pins
shown here as arranged in a circle on the counterpart, and they are
of greater elevation than the counterpart, which by way of example
I have given as the words "Patent combined perforating and embossing
press."
b, b, Figures 4 and 5, are a series of vertical holes corresponding
with the pins a, a, and extending into a groove c in the back of the dic.
Thus when the die is forced down upon the paper or other material on
the counterpart the design engraved on the die (in this case the words
"Patent combined perforating and embossing press ") becomes embossed
upon the said material, while the pins a, a, pass through the material
and form a scrics of perforations therein, the small portions of the
material punched out passing through the holes in the dic b, b, into
the groove c at the back. This part of my Invention for constructing
the die and counterpart so as to emboss and perforate at one operation
will apply to the preparation of documents of various kinds in which
both embossing and perforating are desirable, and more particularly to
the production of ballot or voting papers which require to have a special
stamp visible both on the face and back thereof. The die may be carried
by the plunger, and the counterpart secured to the bed of the press, or
vice versa.
And having now described the nature of my said Invention, and
in what manner the same is to be performed, I declare that I claim,-
First. The construction of embossing, stamping, perforating, or punch-
ing presses with a cam and crank, arranged and acting as herein-before

page_text: described and represented in Figures 1, 2, and 3 of the accompanying
Drawings.
Second. Constructing the die and counterpart of presses so that
they will both emboss and perforate at one operation, as herein-before
described and represented in Figures 4 to 7 of tho accompanying
Drawings.
In witness whereof, I, the said John Pinches, have hereunto sot my
hand and scal, this Twelfth day of February One thousand cight
hundred and seventy-threç.
