PROVISIONAL SPECIFICATION.
Improvements in and relating to Machines for Burnishing and Stitch
Wheeling Boot and Shoe Soles.
ALBERT Cox, of Higham Road, Rushden, in the County of Northamptonshire,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in machines used in the boot and
shoe trade for burnishing and stitch wheeling the soles of boots and shoes.
At the present time the burnishing iron is generally vibrated round a centre
by an eccentric and is made with a shank which is secured in the holder by a
spring, a key, or other equivalent contrivance. These irons have to be changed
in the holder for different thicknesses of sole operated upon and are liable to fall
out of position.
This invention has for its object the provision of simple and efficient means
for vibrating the iron, and the production of a holder carrying a number of irons,
any one of which can readily be moved to its operative position and be securely
held in such positions.
According to this invention the holder for the burnishing iron is carried by
a bracket mounted on a slide which is fitted to move in bearings and is actuated
by a cam mounted on the pulley shaft, or otherwise suitably driven. This cam
may be a box cam giving a number of vibrations to the slide for each revolution
made by the cam, or the slide may be provided with two trucks and the cam
shaped to give a number of vibrations for each revolution and to act as a cam
and a counter-cam, or a separate counter-cam may be used. The holder is fitted
to turn on a fixed axle and is made to receive a number of irons which are held
in position by clips or their equivalent so that the irons are readily changeable,
and there is also a spring catch by which the holder is held with any one of
the irons in its operative position. The holder is also fitted to move vertically
with its axle in the bracket carrying it against the resistance of the spring used
for the catch, or a separate spring may be used if desired. The stitch wheel
is carried by a loose axle which fits a hole in the end of the holder axle and is
secured in position by a screw.

Improvements in and relating to Machines for Burnishing and Stitch
Wheeling Boot and Shoe Soles.
ALBERT Cox, of Higham Road, Rushden, in the County of Northamptonshire,
Engineer, do hereby declare the nature of this invention and in what manner
Price 8d.1

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates to improvements in machines used in the boot and
shoe trade for burnishing and stitch wheeling the soles of boots and shoes.
At the present time the burnishing iron is usually secured in its holder by a
spring, key, or other similar contrivance. These irons have to be changed for
every different thickness of sole operated upon, and are liable to fall out of their
holder.
This invention has for its object the provision of simple and efficient means
for vibrating the burnishing iron, and the construction of a holder carrying more
than one iron and so arranged that any iron can be readily moved into its
operative position and be securely held in such position.
According to this invention the holder is carried by a slide, or preferably by a
lever which is fitted to oscillate on a fixed center and is driven by a three throw
cam which forms its own counter cam: The holder slide, or lever, may however
be actuated by an eccentric, box cam, cam and counter cam or by similar con-
trivances, and preferably the means adopted are arranged to give two or more
motions to the holder for each revolution of the driving shaft. The holder is so
fitted that it can be turned on its carrying axle, and is held in position by a
clutch which is prevented from turning on the holder axle and is held in contact
with the holder by a spring which allows of the clutch being raised when the
holder has to be turned, and also acts as a buffer when the boot sole is being
operated upon. The irons are held in the holder by clips and screws and the
holder is fitted with a stitch wheel and an adjustable guide for such wheel.
In the drawings which accompany this specification
Fig. 1 is a front elevation of the improved holder as made in the form of a
lever.
Fig. 2 is a side elevation of the same.
Fig. 3 is a plan of the holder as viewed from the underside, and
Fig. 4 is the three throw cam used for actuating the iron.
According to the arrangement shown the holder a is carried by a lever b
which is pivotted on an axle fixed to the machine head. The lever is made
with a cross arm c which carries the cam trucks d, both of which can be adjusted
by set screws e for taking up the wear and keeping the lever in a central
position. For oscillating the lever the machine driving shaft is fitted with the
three throw cam f which acts as its own counter cam, while the shaft itself is
driven in the usual manner.
The holder shown is fitted with two irons g which are of a size and shape
corresponding with the soles to be operated upon, and these irons are held in
position by clips and screws i. Below the arm c the lever b forms a spindle j
upon which the holder can turn and slide, and at the bottom of the spindle there
is a screw and washer. Above the boss k of the holder a there is a collar the
lower side of which is provided with teeth which correspond with recesses m
in the boss k whereby the collar and holder are locked together and are kept in
contact by a spring . The collar can by this arrangement be raised clear of
the boss and the holder a be turned so that any one of its irons can be brought
into the operative position, and for convenience in raising the collar / it is fitted
with arms 0. Attached to the arm c is a plate p which is slotted to allow of a
boss or projection 7 of the collar 7 passing through it, and the said boss
the collar turning on its spindle and is bored to receive the axle of the stitch
9 prevents
wheel, a screws being used to hold the axle fast. The plate p also carries
the adjustable guide for the stitch wheel. This guide is made with an axle
which is movable in a boss won the plate p and is held in position by a screw v.
Instead of by the lever b, the spindle j and its connected parts may be carried
by a slide fitted to suitable guides and actuated by a three throw cam, or the
lever en slide may le actuated by an eccentric, or crank, or by a cam and counter
cam, or box cam, and preferably by means which give more than one vibration of
the holder for each revolution of the driving shaft. The holder may be fitted

page_text: with two or more irons, and the collar arranged accordingly, and this latter may
be prevented from turning by keys or like means.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In a machine for burnishing boot and shoe soles a holder carrying two or
more irons any one of which can be brought into its operative position by turning
the holder, a clutch or its equivalent and a spring constructed arranged and
operating substantially as herein shown and described with reference to the
accompanying drawings.
2. In a machine for burnishing boots and shoes, a holder with two or more
irons, a clutch, a spring, a stitch wheel and its guide constructed, combined and
operating in the manner and by the means substantially as herein described with
reference to the accompanying drawings.
