FREDERICK SQUIRE, of Hackney Road in the County of Middlesex,
IMPROVE-
MENTS IN APPARATUS FOR PERFORATING OR PRINTING DESIGNS THROUGH OR UPON,
PAPER, OR OTHER MATERIALS"
My invention relates more especially to apparatus used for punching designs
upon the edges of the wings, toecaps, and other parts of boots and shoes, and it has
for its object a novel method of adjusting and arranging such apparatus, so that
two or more different designs may be produced as desired by the apparatus,
which can be altered and adjusted as either of the designs may be required."
The apparatus consists of a circular horizontal table having a centre pin or stem
below, which fits freely into a socket upon a standard screwed or otherwise fixed
to a workbench or other support. A thumbscrew passes through the side of the
socket, so that the table can be turned round and fixed in any position as desired.
Upon the upper surface of the table are arranged and screwed or otherwise fixed,
preferably round a central boss upon the table, two or more dies having perforations
through them corresponding with the different designs which are to be produced,
and Interal openings into which the edge of the leather to be perforated is
introduced. From the centre of the table rises a cylindrical pin or bar, upon which
fits, so that it can slide vertically up and down for a sufficient distance, a tubular
socket upon the lower edge of which is formed or attached a disc the lower face of
which is parallel with the table already described, and upon the said lower face are
fixed sets of punches corresponding with the holes in the dies upon the table below.
The sets of punches are preferably arranged and fixed upon a separate plate which
can itself be screwed upon the lower face of the disc. The upper end of the socket
upon the disc is closed with the exception of a hole through which a central rod
passes, the external end of the rod being provided with a screwed nut, or washer
and pin or key, and the rod is extended downward through a central opening
passing completely through the entire apparatus, the lower end of the rod being
provided with a hook or other attachment by which it can be connected to a lever

when the treadle is depressed the socket and plate are forcibly drawn down by the
rod, and the punches are caused to perforate the leather placed in the proper
position in the dies. In order to raise the punches, a helical or other spring is
arranged in the upper socket round the rod, and a screw is arranged in the side of
the socket, its point entering a groove in the cylindrical bar upon which the socket
slides, so that the punches are guided in the proper position and the height to
which they are raised by the spring is regulated. Either of the sets of punches
and dies can be used as may be desired by the attendant, and by loosening the
lower setscrew the entire apparatus can be instantly turned round in the lower
socket when desired in order to bring another set into operation.
Apparatus constructed according to my invention may be used for the purpose
of perforating leather as described, or paper, metal, or other material. Or stamps,
or printing blocks, of any suitable material, may be substituted for the punches
and dies, a suitable ink being applied to their surface in any convenient manner
