COMPLETE SPECIFICATION.
An Improved Press for Leather Caps or Stiffeners for Boots and
Shoes and like Purposes.
I FRIEDRICH AUGUST KEIL Manufacturer of Arnstadt Thuringen in the Principality
of Schwarzburg-Sondershausen and German Empire, 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 improved leather cap press is shown in front elevation in Figure 1, in cross
section (on line A B of Figure 1) in Figure 2, in plan in Figure 3 on line CD of
Figure 1, and consists of the base plate a upon which are fixed two bearings carry-
ing the shaft upon which are mounted the eccentric band the hand lever c. The
pressure exerted on the hinged rode moving in the guides d by the lever c with
the aid of the eccentric is transmitted by the roller S secured to the said rod on to
the sides or cheeks f moving on centres and . The latter operate simultaneously
from behind and on both sides upon the die g which has to be changed according
to the size of the cap which is being made as shown in Figures 2, 3 and 5. Figures 8ª
8 & 8 show respectively a side view a front view and a top view of the said die
which is held in position by the dovetail piece ». The sides or cheeks fof the press
are furnished with appendages or projections which are firmly secured on the said
checks on the one hand and which fit on the other the shape of the die g having
also to be changed like the latter. The two spiral springs i withdraw the press sides
or cheeks with appendages from the die g when the lever is brought back into
its original position. The mould box K shown in a closed position in Figure 4 and
in an open position in Figure 5. consists of three parts and ³ connected
together by draw rods and bears (as shown in Figures 1 and 2) upon the sides or
cheeks upon the appendages and upon the stamp and is capable of moving
upon the hinge turning upon the pin or pivot m. The mould box K is simultaneously
drawn over the die g in front and on both sides thereof by means of the second
lever n oscillating at o. Upon this box K rests a cover or pressure plate p provided
with an opening and shown separately in Figure 6 and likewise on Figures 1 and 2.
This plate is firmly pushed (by means of the four strong spiral springs wound upon
rods provided with screw threaded ends and nuts as shown in Figures 1 and 2) upon
the mould box K and hence also upon the parts fh and g placed thereunder.
The opening in the cover plate p is closed by the sliding plate 9 (Figures 1
and 2) particularly shown in Figures 7ª 7 and 7°.
The machine operates as follows:-
The leather previously operated upon by the cap bending machine is placed
around the die g between the latter and the projections of the pieces or cheeks f
the turned over edge of the cap being uppermost (Figure 8); this is effected after
the sliding lid has been removed and the mould box K has been opened by the
lever n the sides or cheeks with the appendages having been likewise opened by
the lever c.
Now the said cheeks fare firmly pressed by means of the lever against
the leather in the die the opening formed in the pressure plate p is closed by the
sliding lid q and the mould box K is drawn by the lever n over the edges of the cap
placed upon the die g (see Figures 8° 8° 8°). The die g is heated by a gas flame
placed under the latter and the leather-daniped before the operation-is dried and
fixed in the shape of a cap (for stiffening the hind parts of boots and shoes and for
the like purposes) formed by the cap bending machine and the cap process.

page_text: 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 leather cap press in which a shaft carried in bearings upon a base plate and
provided with a hand lever c moves an eccentric b in such a manner that the latter
can operate by means of rollers arranged at the end of a rod e upon two symetrically
formed pressure cheeks or sides f which surround the changeable appendages and
so that the leather previously prepared by a bending machine is introduced between y
and h and pressed by the cheeks or sides while at the same time a pressure is applied
to the upper bent over leather edge or flange by the closing of a mould box composed
of three parts ¹² k³ connected together by draw bars this closure being effected by
the hand lever n and a cover or pressure plate p pressed perpendicularly in a down-
ward direction by means of 4 spiral springs wound upon suitable screw rods furnished
with nuts and having a transverse closing lid q which draw the cap edges regularly
towards the middle of the die g substantially as hereinbefore described and illustrated
in the drawings hereunto annexed.
