PROVISIONAL SPECIFICATION.
Improvements in or relating to Machinery Employed in the
Manufacture of Boots and Shoes.
We, SAMUEL JOHN PEGG and SAMUEL ARTHUR PEGG, of S. Pegg & Sons, Alexander
Street, Leicester, Engineers to the Boot Trade, do hereby declare the nature of
this invention to be as follows:-
This invention has reference to machinery employed in the manufacture of
boots and shoes such for example as cutting presses, boot heeling machines,
embossing, stamping, and guillotine machines, haying a vertically reciprocating
head.
The invention has for its object to provide improved driving gear whereby
a more compact machine can be produced; in addition to which the gear wheels
are enclosed and there is less risk of injury to the workmen.
To carry out our invention we mount upon the driving shaft so as to revolve
loosely thereon a pulley having preferably an integral rim and face. Centrally
over the inner side of the pulley face is an integral small spur wheel passed
also over the driving shaft and engaging a spur wheel loosely carried on an
arbor or axle projecting from the inner face of the pulley.
The latter, spur wheel is also combined with a smaller spur wheel partaking of
its motion and gearing with a toothed wheel keyed fast on the shaft so that the
latter is revolved thereby.
The other face of the pulley is slidable on the shaft and when moved in position
by a pivotted or clutch lever or equivalent, encloses the whole of the gearing
within the pulley.

Improvements in or relating to Machinery Employed in the
Manufacture of Boots and Shoes.
We, SAMUEL JOHN PEGG and SAMUEL ARTHUR PEGG, of S. Pegg & Sons, Alexander
Street, Leicester, Engineers to the Boot Trade, 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 invention has reference to machinery employed in the manufacture of
boots and shoes such for example as cutting presses, boot heeling machines,
embossing, stamping, and guillotine machines, having a vertically reciprocating
head.
The invention has for its object to provide improved driving gear whereby
a more compact machine can be produced; in addition to which the gear wheels
are enclosed and there is less risk of injury to the workmen.

page_text: The invention will be understood from the following further description in
reference to the accompanying drawings in which,
Figure 1 is a perspective view of a double cutting press having our invention
embodied therein.
Figure 2 is an elevation of the improved driving gear with part of the cover
broken away, and..
Figure 3 is a central transverse section of the same, both of the said Figures 2
and 3 being drawn to a larger scale, than -Figure 1.
Upon the driving shaft A there is loosely mounted a belt pulley B having an
integral rim B¹, face B2 and spur wheel B³. (Figures 2 and 3) the latter being
formed or cast on the opposite face to B.
The spur pinion B³ gears with one or two larger toothed wheels C as shown
the latter having cast therewith a small spur wheel C₁ each being loosely carried
upon an axle or arbor D projecting from the adjacent face of a disc or cover
plate E also loosely fitted upon the driving shaft.
The screwed end of the arbor passes through to the exterior face of the cover
plate against which it is fixed by a nut D.
The small spur C¹ gears with another spur wheel F of larger diameter fixed by
a key E or otherwise upon the driving shaft.
The cover plate is slidable on the driving shaft by removing the nuts D¹ to
gain access to the gear wheels.
Two stops or angle plates G fixed by bolts G₁ to the exterior of the cover
plate E and adapted to abut against some fixed part of the framing H as indicated
in Figure 1; prevent any rotary movement of the said cover plate.
In the machine shown in Figure 1, split bearings J are provided for the driving
shaft so that the latter and its driving gear can be moved bodily into and out of
position when desired.
The action which will be readily understood is as follows:-
:--
Upon the pulley B being driven by a belt in the usual manner, it and the rim B¹,
face B and pinion B3 will be revolved thereby, the latter gearing with spur
wheels C will rotate them and their attached smaller spur gears C and these
latter gears will drive the toothed wheel F and the driving shaft A upon which
it is keyed fast.
As most clearly shown in Figures 1 and 3 the parts B, B1, B2, E form à com-
plete pulley in which the whole of the gear wheels are enclosed.
The rim B might be omitted but the construction herein described and shown
is preferred.
K is the vertically reciprocating head of the press and it is actuated by an.
eccentric on the driving shaft in the usual manner.
L is a usual loose pulley on the driving shaft.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
:-
1. In machines of the character described the combination with the driving
shaft A and a spur wheel F fixed thereon of belt pulley B B2 and disc E mounted
loosely on the driving shaft and having gear wheels on their adjacent faces gear-
ing with each other and with a toothed wheel fixed on the driving shaft to drive
the latter substantially as described.
2. In machines of the character described the improved arrangement of driving
mechanism operating substantially as described and illustrated in the accom
panying drawings.
