PROVISIONAL SPECIFICATION.
Improvements in or applicable to Scalloping and Punching
Machines.
We, FREDERICK SQUIRE and FREDERICK SQUIRE the Younger, both of
122, Hackney Road, in the County of London, Engineers, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in the machines employed for scalloping
and punching leather for the toe-caps, vamps, and other parts of boot and
shoe uppers.
In the said machines as hitherto constructed it has been found that the
composition or other soft roller on which the material to be scalloped or punched
is placed becomes grooved by the cutters constantly working in one position on
the periphery of the roller so that it becomes necessary to frequently re-surface
the periphery of the roller which operation is attended with considerable expense
and loss of time.
The object of our invention is to overcome this objection.
For this purpose we adapt to the machine, mechanism whereby as the cutter spindle
is turned the cutter is slowly moved backwards and forwards across the periphery
of the roller so that practically, the whole surface of the roller wears evenly and
does not often require to be re-surfaced.
A suitable arrangement for effecting the to-and-fro movement of the cutter
consists in fitting the cutter shaft so that it can slide in its bearings, a suitable part
of the said shaft being cut with a worm adapted to gear with a worm wheel which
works in a bearing on a carriage fixed to the shaft a spring catch rod being
provided adapted to take into eccentrically placed holes on the side of the worm
wheel to allow of regulating the extent of the backward and forward movement or
throw of the cutter.
In some cases instead of reciprocating the cutting wheel across the periphery of
the roller as hereinbefore described we may reciprocate the roller under the cutter
but we do not advise this arrangement.

Improvements in or applicable to Scalloping and Punching
Machines.
We, FREDERICK SQUIRE and FREDERICK SQUIRE the Younger, both of
122, Hackney Road, in the County of London, Engineers, 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 :-

of time.
The object of our invention is to overcome this objection.
For this purpose we adapt to the machine, mechanism, whereby as the cutter
spindle is turned, the cutter is slowly moved backwards and forwards across the
periphery of the roller so that practically the whole surface of the roller wears
evenly and does not often require to be re-surfaced.
A suitable arrangement for effecting the to-and-fro movement of the cutter
consists in fitting the cutter-shaft so that it can slide in its bearings, a suitable
part of the said shaft being cut with a worm adapted to gear with a worm wheel
which works in a bearing on a carriage fixed to the shaft, a spring-catch rod being
provided adapted to take into eccentrically placed holes on the side of the worm
wheel to allow of regulating the extent of the backward and forward movement or
throw of the cutter.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawings, in which :-
--
Figure 1 is a front elevation of our improved machine the lower part of the
framing being broken away; and,
Figure 2 is a plan of Figure 1 partly in section:
Figure 3 is a section on the line 3-3, Figure 1.
a indicates so much of the frame of the machine as is necessary to illustrate our
invention, b is the usual roller for supporting the material to be scalloped or punched,
and c the spindle carrying the cutter d, which spindle is of such length that it is capable
of being moved longitudinally in its bearings a distance approximately corresponding
to the width of the face of the roller b, d', d' being the bearings in the frame a in
which the said spindle is mounted.
e is the screw-thread or worm which is preferably cut upon the spindle, and f is
the wheel with which the said worm engages, the said wheelf being mounted upon
a pin or stud g upon a bracket g¹ carried by the shaft e in such a manner that the
said bracket permits of the said shaft rotating therein but cannot move longi-
tudinally independently of the said shaft. As shewn in the drawings, the
longitudinal movement of the bracket g¹ relatively with the shaft c is prevented by
passing a pin through one of the bosses g³ formed upon the bracket for supporting
it upon the said shaft into a circumferential groove h cut in the shaft, as clearly
shewn in Figure 3.
i is a spring connecting rod one end of which is pivotted to the bracket a at j
whilst the other end carries a pink which is designed to enter one of a series of
holes, formed in the face of the worm wheel . With this arrangement it will
be obvious that as the shaft c is rotated, rotary motion will also be imparted to the
worm wheel and that, as the said worm wheel has engaging with it the pin k upon
the connecting rod i which is immovable longitudinally, a longitudinal movement of
the bracket carrying the worm wheel and also the shaft c upon which the
bracket is mounted will be effected. The length of the traverse of the shaft
carrying the cutter will depend upon the particular hole with which the pin on the
connecting rod engages, the said holes being arranged at slightly varying distances
from the centre of the worm wheel.
im is a guide pin fixed to the frame a and passing through a lug at the back of
the bracket g, the said pin serving to maintain the said bracket g' in its proper
position relatively with the plane of movement of the rod i.
In some cases instead of reciprocating the cutter across the periphery of the
roller as hereinbefore described, we may reciprocate the roller under the cutter
but we do not advise this arrangement.

page_text: Having now particularly described and ascertained the nature of our said inven-
ion and in what manner the same is to be performed, we declare that what
we claim is :-
1. In a scalloping or punching machine an arrangement of mechanism whereby
the cutter and the roller upon which the work to be cut is supported can be moved
relatively with one another, substantially as described.
2. In a scalloping and punching machine the arrangement of the shaft carrying
the cutter so that it may be caused to move longitudinally in its bearings,
substantially as, and for the purpose, described.
3. In a scalloping and punching machine in which the cutter is arranged to be
traversed across the face of the roller upon which the material to be cut is
supported, means, substantially as herein before described and illustrated in the
accompanying drawings, for effecting such traverse of the cutter, as set forth.
