PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cutting Leather and the like.
We, ROBERT JOYNES. BAGGALEY of Burford Road, in the Borough of Nottingham
Patent Slipper and Cork-sock manufacturer, and FREDERICK BOARDMAN of Daybrook
in the County of Nottingham, Leather cutter, do hereby declare the nature of this
invention to be as follows :-
This invention relates to apparatus for cutting leather and similar materials into
parallel strips such as laces, straps or the like and it has for its object improvements
in-such apparatus so that the process of cutting may be performed better and in a more'.
expeditious manner than heretofore.
In carrying out this invention we employ a circular revolving drum of suitable
dimensions which is carried on a shaft running in bearings formed in or attached to
two end standards connected to each other by suitable tie rods. Immediately above
the drum and parallel to it is a shaft carried in adjustable bearings sliding in vertical
slides formed in the end standards.
On this shaft we arrange at convenient distances apart corresponding to the width
it is desired to cut the material a number of circular cutters with preferably knife
edges which bear against the periphery of the drum; this cutter shaft may be driven
by the direct action of a belt and pulley or may be connected to a driving shaft by'
convenient gearing, and may be provided with a fly-wheel. The shaft carrying the.
drum may be connected to the cutter shaft by a vertical shaft carried in bearings
secured to one of the standards and connected by bevel whools at its upper ond
to the cutter shaft and by a worm at its lower end engaging with a worm wheel' on
the drum shaft:
The leather or material to be cut is secured by one of its ends to the drum. by
pressing it over projecting pins or in any other convenient manner and is gradually-
fed forward by the drum as the cutters-revolve.
To adjust the leather or other material'on the drum the cutter shaft may be raised'
by the action of screws or levers acting on the adjustable bearings and depressed by
the same means.
In some cases fixed knives may be used; in this case motion is imparted to the
drum in any suitable manner.
To prevent the drum from injuring the sharp edge of the cutters it is preferably
covered with a layer of paper pulp or other suitable material!

Improvements in Apparatus for Cutting Leather and the like!
We, ROBERT JOYNES BAGGALEY of Burford Road, in the Borough of Nottinghain,
Patent Slipper and Cork sock manufacturer and FREDERICK BOARDMAN of Daybrook,
in the County of Nottingham, Leather Cutler, 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 relates to apparatus for cutting leather and similar material into
parallel strips such as laces, straps, or the like and it has for its object improvements
in such apparatus so that the process of cutting may be performed in a
expeditious manner than heretofore.
more
It will be best understood by reference to the accompanying..drawings in which
Fig. 1 is an end elevation and Fig: 2'a plan of the apparatus.

page_text: In carrying out this invention we preferably employ a circular revolving drum A
of suitable dimensions which is carried on a shaft B running in bearings attached
to the two end standards D secured to each other by tie rods D. Above the
drum A and parallel to it is a cutter shaft E carried in adjustable bearings F
sliding in vertical slides formed in the end standards D, the bearings are depressed
by means of screws G carried by the caps G¹ and are raised by the spring controlled
studs H when the screws G are released.
: On the cutter shaft E we arrange a number of circular cutters I formed preferably
with finely serrated edges which bear against the periphery of the drum A.
Between
the cutters may be placed washers or distance pieces of any suitable thickness
according to the width it is desired to cut the material the whole being held firmly in
position by a screwed nut J.
The drum A and cutter shaft E are preferably driven by a driving shaft K provided
with pulleys L and carried in bearings K' secured to the end standards D, the drum A
is connected to the driving shaft K by a pinion M secured on the latter gearing with
a spur wheel M¹ secured on the end of the drum. If desired the pinion M may
be adapted to slide on the shaft K so as to be thrown out of gear when desired, the
cutter shaft E is also connected to the driving shaft K by two spur wheels N and N¹
secured on the ends of the two shafts E and K respectively. The leather or material
to be cut is secured by one of its ends to the drum A by pressing it over projecting
pins or placing it under a clip O placed in a longitudinal recess in the drum and
thus secured by depressing the clip O by means of screws 01.
As the drum A
rotates the material is fed forward and is cut by the cutters I as they revolve, the
shaft E on which they are carried being depressed to the desired extent by the
screws G acting on the end bearings F. When cutting material of great length one
or more feed rollers carried in suitable bearings may be used and the material fed
forward continuously.
To prevent the drum from injuring the cutting edge of the cutters it is preferably
covered with a layer P of paper pulp gutta percha, or other suitable material.
To automatically stop the apparatus at each revolution of the drum when the belt
is on the fast pulley the rod carrying the belt fork is held in position by the upper
end of the lever R which is pivotted at R' engaging with a catch Q on the rod Q
the lower end of the lever R is provided with an anti-friction roller S which is
raised by a cam T on the shaft B of the drum and the upper end of the lever is
forced out of engagement with the catch Q when the belt is returned to the loose
pulley by the action of the spring U on the rod Q.
In some cases instead of a revolving drum A a flat platform may be used which
may run on slides or anti-friction rollers and be operated by a rack and pinion or
other suitable mechanical arrangement.
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 apparatus such as described the combination with cutters such as I of a
rotating drum such as A to which the material is secured and fed to the cutters
substantially as described and illustrated in the accompanying drawings.
2. The combination and arrangement of parts forming the complete apparatus for
cutting leather and like material substantially as herein described and illustrated in
the accompanying drawings.
