PROVISIONAL SPECIFICATION.
An Improved Recording Mechanism for Stamping or Embossing
Presses.
We, THOMAS ARTHUR COLLS of Ringsfield Villa, Huddleston Road, Tufnell
Park, and LEONARD HOLLINGWORTH CLARK of 9 Fairholt Road, Stoke
Newington, both Civil Servants, of London, do hereby declare the nature of this
invention to be as follows:-
This invention is designed to provide an automatic register for recording the
number of times an embossing press or stamp has been operated.
To effect this we place on the back of the die a small letter, number or other
distinguishing mark, and on the ram of the press a corresponding matrix, or vice
versa.
By means of a small chamber interposed between the ram and the die and of a
spring operating so as to keep the ram and die apart, we obtain space for the
passage of a recording band or ribbon or strip, of paper or other suitable material,
which is automatically and intermittently fed through the chamber, in such a way
as to receive an impression every time the die struck on the matrix, and to
present a fresh surface at each moment of impact.
Instead of causing this operation to take place behind or above the die we can
if preferred cause it to take place in a similar manner behind or below the matrix.

COMPLETE SPECIFICATION.
An Improved Recording Mechanism for Stamping or Embossing
Presses.
We, THOMAS ARTHUR COLLS of Ringsfield Villa, Huddleston Road, Tufnell
Park, and LEONARD HOLLINGWORTH CLARK, of 9 Fairholt Road, Stoke
Newington, both of London, Civil Servants, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention is designed to supply an automatic register for recording the
number of times an embossing press or stamping machine has been operated, and
consequently the number of impressions made by it.
To effect this we introduce the following mechanical arrangement between the
ram of the press and the die, and we form on the back of the die a letter, figure,
or other device, and we make a corresponding matrix when required on the lower
face of the ram. If preferred the position of this upper matrix and die can be
reversed, the letter or figure being placed uppermost, and the matrix beneath.
We will now describe the invention with reference to the accompanying drawings,
in which Fig. 1 shows an elevation and Fig. 2 a plan of the mechanism which we
add to the press.
In order not to complicate the drawing we have omitted the
arrangements of levers, ratchets, and pawls, which have nothing novel in them,
but are of the usual and well known character. The first of these is fixed at the
back of the mechanism and serves to impart a regulated intermittent motion to
the paper rollers whereby at each stroke of the press the rollers are urged forward
one step on the ratchet and a fresh surface of the roll of paper is exposed to the

action of the upper die. The second arrangement similarly winds up the slack of
the paper on the roller h¹.
Returning to the drawings; a, is the ram head of the press. b, is the die of the
c, is the die-tail upon which our recording letter or figure is engraved.
same.
d, is an intermediate block or ram which rises and falls about one-sixteenth of an
inch from the die tail in consequence of the pressure of the spring or springs e, e,
on the shoulder of the frame f.
is the frame of our device.
9, 9, are two pins which regulate the travel of the block d.
h, h', are two flanged wheels which hold the paper tape which is first wound on h,
and passes to ', after receiving the record.
i i, i, are two guide rollers between which the paper passes on its way to the
space k, where it receives the impression from the die-tail."

k, is the space where the record is made.
,, are two cog-wheels connecting the two rollers,. These rollers draw the
paper forward and pass it on to the paper roller /'.
m, is the matrix of the press.
n, is the shank whereby our mechanism is connected to the ram head.
It will be readily understood from the foregoing description that the ordinary
action of the press is not interfered with, and that in consequence of our improve-
ments the press itself at every down-stroke of the ram automatically effects a
record on the roll of paper.
Instead of passing the paper above the die-tail we can if preferred adapt our
improvements so as to place the space k, below the matrix m, and attach the
paper rollers to the fixed block in which the matrix is placed. In that case the
spring or springs e, e, will be placed below the matrix. We prefer however to
place our recording mechanism on the ram as shewn.
The impression can be either embossed on the strip of paper or printed by means
of a carbonic ribbon or other appliance for inking the said letter or figure.
The paper rollers and recording mechanism can if preferred be enclosed and
secured by lock and key.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
-
An automatic recording mechanism for registering the number of strokes made
by a stamping or embossing press consisting of the frame, with ram d, and shank n,
the spring or springs e, e, the rollers i, i, and,, the cog-wheels 1, l', the paper
rollers h, ', the pins g, g', together with the feeding and winding up arrangements
of levers, pawls and ratchets, as herein described and set forth.
