PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Inserting Studs or Rivets in Boot
Soles and Heels.
1 RICHARD POORE of 33 Chaucer Road, Herne Hill, S.E., Engineer, do hereby.
declare the nature of this invention.to be as follows:
This invention has reference to the formation of a wearing surface for the soles
and heels of boots and shoes, in the manner described in the Letters Patent
granted to J. H. Borrett, dated 13th May 1891, No. 8220, in which hollow studs
or rivets are driven through the leather sole or last lift of the heel from the back.
Hitherto this operation has been effected by hand, at the cost of much time, and
with the risk of unevenness in the work, and the object of the present invention is
to provide a convenient apparatus in which the whole of the studs or rivets may
be driven at one time.
In carrying out this invention, I provide a base plate in which I secure a
number of punches or driving instruments. These punches just enter holes in a
second plate, which is mounted in suitable guides provided with springs, the
operation of which is to keep the perforated plate raised.
Upon this perforated plate I secure, in any convenient manner, a template
to receive the sole or heel leather.
In operating this apparatus, the studs or rivets, with the head downwards, are
inserted in the holes. The piece of leather is then placed in the template, and a
flat plate is then put over it.
The apparatus thus prepared is placed in a suitable press, and the perforated
plate, with its accessories, is forced down, by which operation the punches are
caused to drive the studs or rivets through the leather.
In practice, the press will be large enough to receive, say, six of these driving,
apparatus, so that a large number of soles may be operated upon in a short time.
Dated this 21st day of March 1896.

Improvements in Apparatus for Inserting Studs or Rivets in Boot
Soles and Heels.
1 RICHARD POORE of 33 Chaucer Road, Herne Hill, S.E., Engineer, 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 :-
Wearing surfaces for the soles and heels of boots and shoes have been produced
by forcing through the sole and the bottom lift of the heel, hollow studs or pieces,
which, on their passage through the leather, become filled with plugs of leather in

page_text: a high state of compression, and these plugs of compressed leather, in combination
with the metal rims, constitute an eminently durable wearing surface.
Hitherto these studs have been forced into the leather by hand, which does not
produce a satisfactory result, and the object of this invention is to provide a
simple and efficient machine for inserting all the studs for a sole at one time.
In the accompanying drawing,
Fig. 1 is a vertical section taken on the line X-X, Fig. 2, of the machine
which I employ for the above purpose,
Fig. 2 being a sectional plan taken on the line Z, Z, of Fig. 1.
A is a base plate formed with pillars A' at the four corners. These pillars, A',
may be hollow, as indicated in the drawing, to form guides for pins, or they may
be solid, as hereafter explained.
C is a plate provided at its corners with pendent pins C', which enter and fit
the hollow pillars A. These pillars and pins thus form guides to maintain the
correct relative positions of the plates A and C.
If the pillars are solid, they will be formed with shoulders, and cylindrical
projections, which enter corresponding holes in the plate C.
Mounted on the pillars are strong spiral springs D, the office of which is to
support the plate Cat, and return it to, its normal position, during the working of
the machine.
B B are drivers or plungers which are fitted to the plate A and enter holes in
the plate C. When the plate C is in its normal position, a space will be left
between the top of the plunger and the top of the plate, as shewn in the drawings
at C2, to receive the hollow studs.
E is a template, which is recessed to receive the sole leather or heel lift to be
studded, as the case may be.
The size of the machine, and the position of the plungers, will of course vary
according to the size of the solo or heel to be operated upon.
The working of the machine is as follows:-
The hollow studs are inserted in the recesses C2 of the plate C, so that the
heads will rest on the top of the plungers B. A leather sole is next placed in the
recess of the template E, and is preferably covered over with a plate. The head
of the press, or a plate attached to the plunger, will serve the same purpose.
The machine is then pushed into a press of any suitable construction, and
pressure being applied (whether at top or from below is of no consequence), the
studs are driven through the leather sole, becoming filled with the plugs of leather,
as before explained.
When the pressure is relaxed, the machine is removed from the press, another
filled machine taking its place. The studded sole is then removed from the first
machine, which is again filled ready for the press.
It will of course be obvious that the machine may, if desired, be formed to stud
a pair of soles and heels at one time.
It will also be obvious that the minor mechanical details is to be varied without
departing from the nature of the invention.
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:-
A machine for studding the soles and heels of boots and shoes, and consisting of
a base plate having a series of plungers, a spring supported movable plate to carry
the leather, means for guiding the plate in its movement, the fixed plungers
working in holes in the said movable plate, and a template, as set forth.
