PROVISIONAL SPECIFICATION left by John Singleton Copley Hill
and Edwin Cottrill at the Office of the Commissioners of Patents,
with their Petition, on the 14th November 1853.
We, JOHN SINGLETON COPLEY HILL, of Birmingham, in the County of
Warwick, Gentleman, and EDWIN COTTRILL, of Birmingham aforesaid,
Manufacturer, do hereby declare the nature of the said Invention for
"AN IMPROVEMENT OR IMPROVEMENTS IN STAMPS AND PRESSES, A PART OR
PARTS OF WHICH IMPROVEMENTS MAY BE APPLIED TO OTHER PURPOSES," to be
as follows:
Our Invention consists in applying to embossing and other presses
a registering machine, for the purpose of registering the number of
impressions taken by the said machine, and also applying thereto
mechanism for preventing the taking of impressions fraudulently from
the said machine. We will illustrate our Invention by reference to an
embossing press. We attach an arm or lever to the bolt or plunger
of the press, which said lever on the rising of the bolt acts on the

page_text: registering apparatus fixed on the frame of the press, and registers
each such motion of the press. In order to prevent the introduction
of paper or other matter under the die of the press, before the bolt
carrying the said die has risen sufficiently high to register its motion,
we place a ring or short tube around the matrix or lower die. The
said ring is connected by a series of levers with the bolt carrying the
upper die, and on the rising of the bolt the said ring rises and closes
the space between the two dies. When, however, the bolt has risen so
high as to have acted on the registering apparatus, the said ring is
disengaged and falls down around the lower die, and paper may now
be introduced between the dies and an impression taken. Our
registering machine consists of two or more discs, each having a
hundred or other suitable number of teeth on its periphery an arm or
lever acted on by the press carries a click, which engaging in the teeth
of the first disc moves he said disc through one hundredth part of a
revolution at each stroke. When this disc has moved round once, and
when the number one hundred has to be registered, a spring on the
said disc coming against a fixed stop is made to engage in a hole in
the face of the next disc (which is parallel and close to the former), and
moves it through one hundredth part of a revolution and registers one
(equal to one hundred) upon it; but the spring described having passed
the said fixed stop disengages itself from the second or hundreds disc,
and does not act on it again till the first disc has performed a second
revolution, when it registers two (equal to two hundred). Fingers
connected with the two discs indicate upon a dial the number of strokes
taken by the press, by means of two fingers similar to those of a clock.
This machine does not register till the die is brought down upon
the matrix. Although we prefer using the registering machine last
described, yet we do not limit ourselves to the same, as other registering
machines may be employed in carrying our Invention into effect.
Our registering machine may be applied to registering purposes
generally.
