A Press for Stamping in Relief and Colour Paper, Parchment, and
other Material, Dating the Stamps and Recording their Values
in a Tabular Form upon a Web of Paper.
I, THOMAS PEACOCK of 6 Park Road, Forest Hill, London, S.E. and of the
Office of Inland Revenue, Somerset House 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 :-
The press has one screw staniping head A with inking arrangement J attached,
which head, after the dies have received the colour from rollers J, impresses them
by its descent upon the material to be stamped. The dies B, of which there are 32
or any appropriate number, are securely held in a circular horizontal metal ring C,
which revolves freely upon three equidistant conical edged wheels D fitting into a
groove (D D) in the under surface of the ring C. The duties or values of the dies
are shewn, for the guidance of the operator, by figures engraved upon the periphery
of the ring.
The dies themselves B are of special form, with a shoulder top and bottom, and
a cylindrical stem on which is a coil spring which keeps them to an accurate inking
level. In front of the periphery of the ring, C, one set of date pieces, E (day,
month, and year), corresponding with the date of the impressment of the stamps, is
attached to that part of the head which gives the embossment (the plunger A A),
which set of date pieces descends with the dies and joins with and completes each
die as it is used in producing the stamps, the one set of date pieces serving
for all the dies. These date pieces are held in position and released when required
by hinged flap, 6, and thumb screw, 5. The ring, C, is moved by the finger of
the operator applied to the notches, F, in its vertical edge, bringing the dies
as required under the plunger, A A. The levers, W, are moved by the ascent
and descent of the fly wheel, A, the groove, X, receiving and actuating a small
roller at the end of the lever. On the upper surface of ring, C, are fixed,
horizontally, type pieces, T, denoting the values expressed by the respective
dies. These type pieces are inked by suitable rollers in connection with levers, W.
As each stamping die is brought down upon the material to be stamped a roll of
paper, G, is also brought down by levers aud links, W, upon the type piece which
corresponds in value with the die. This imprints the value of the stamp upon the
roll. Roll, G, is carried by frame, Y, which slides upon polished steel bars 1, 2, 3,
and engages into a small roller fitting into a worm cut upon the face of the
cylinder, H. This cylinder, which is revolved by a star wheel and detents actuated
by lever W, gives by means of the worm and roller, a lateral movement to the
roll. The successive imprints form lines of values upon the paper. At the
completion of each line the paper is fed forward by a ratchet in connexion with
lever, W, and the repetition of the lines produces columns of amounts upon the
paper. As it is printed the paper falls through a slit in the table of the press and
is gathered into a cupboard, S, to be cut off from the roll from time to time and
the columns cast up and compared with the cash taken for the stamps impressed.
A ratchet and catch, I, are attached to the head, A, of the press, and a rack to
the moving die holder, A A. This arrangement, after a stamp has been impressed,
permits the die to rise for a fresh blow but will cot allow it to be brought down till
it occupies a position which compels a record to be effectually taken. A
compressible coil spring in the head of the press holds the die down upon the paper
securely till the die holder rises to this secure position.

page_text: The inking of the stamp dies is effected by small rollers, J, which rise through
an opening in the table in the front of the die, lifting a hinged lid, K, which
protects the paper which is being stamped from being soiled by the colour.
A treadle, L, actuates a vertical rocking bar, M, and a bolt, N, which is connected
with it by means of a projecting wedge which is attached to M and passes through
a slot in N. The movement of this wedge pushes the bolt in and out of ring C,
to fix its stamping position. This bar is carried by stud 4. When the die ring is
being moved the treadle L is depressed and the rocking bar passes under the fly
wheel of the stamping head, preventing its descent and releasing the bolt from the
ring. When the die is in its proper position the operator's foot is released from
the treadle and the rocking bar retires from the head, the bolt passing into and
securing the ring.
All the working parts of the press are protected by moveable covers, P, secured
by locks which prevent the mechanism being tampered with during the use of the
press, and the movement of the head or access to the dies when the machine is out
of use.
The principal drawing shews the general plan and construction of the press.
The detail drawing shews one of the dies with part of the carrying ring C in
elevation and plan. Also the arrangement of the date plugs.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
1. The arrangement of the date pieces common to all the dies of the press.
2. The paper recording apparatus in connexion with the movement of the press
head and dies.
3. The form of the dies and the die ring and carrier.
4. The arrangement of the rocking bar and bolt working between the press head
and the ring.
5. The general conformation of and the arrangement of the parts of the mechanism
and their protective casing.
