Improvements in and relating to Heel Burnishing Machines.
We, JOSIAH GIMSON, JOSLAH MENTOR GEMSON, ARTHUR JAMES GIMSON and
SYDNEY ANSELL GIMSON all of the firm of Gimson and Company of the Vulcan
Works, Vulcan Street, Leicester in the county of Leicester, Engineers, do hereby
declare the nature of this invention to be as follows:-
This invention is for improvements in and relating to heel burnishing machines to
obtain a steadier movement and tension to the oscillating burnishing arm the end
of the burnishing shaft carrying a toothed wheel to which is geared a quadrant
carried on an angle piece having a boss in the centre fitting on a central pin, the
angle piece being attached to an eccentric fitted on the driving shaft of the machine
whereby the rocking motion is given to the rubbing block, that is in those machines
known as "Tapleys Heel burnishing machines." These machines having to be
driven at a great speed the above mentioned device constantly loses power and
breaks near the centre or axle box of the quadrant, the lower portion or angle piece
working in an oblique direction, and also by the use of the flat curved spring
coming under the burnishing device the tension on the burnishing arm when rising
or falling does not allow the polishing or burnishing of the upper part of the heel
to be done expediciously. To obviate these defects is the present invention intended,
to obtain a regular oscillating movement to the burnishing block and arm and a
uniform tension to the rising or falling of the rubbing block at any angle during the
burnishing of the heel. To effect this we employ a vertical straight rack bar having
teeth on that face fitting to the toothed wheel and held to the wheel by a rocking
guide forming part of the said vertical rack bar, which is secured at its lower end to
an eccentric pin on a disc, or eccentric cam, adjusted on the inner end of the driving
shaft that when the belt is put upon the driving pulley. The up and down movement
is given to the rack bar geared to the toothed wheel on end of the shaft in the
burnishing device. By this means a steady motion is conveyed to the oscillating

page_text: rubbing block heated for burnishing the heels of boots and shoes and a uniform
tension is also given to the burnishing arm and rubbing block by using in the place
of the flat curved spring now employed a spiral steel spring attached at its inner
end to the front socket of the burnishing arm, and the outer end attached to a
compensating forked lever riding at the end of the burnishing arm which lever is
acted upon by the rising and falling of the burnishing arm to keep the tension or
regulated pressure upon the heel of a boot or shoe when it is brought up to the
burnishing or rubbing block.

We, JOSIAH MENTOR GIMSON, JOSIAH GIMSON, ARTHUR JAMES GIMSON, and
SYDNEY ANSELL GIMSON, all of the firm of Gimson and Company of the Vulcan
Works, Vulcan Street, Leicester in the county of Leicester, 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 :—
This invention is for improvements in and relating to heel burnishing machines
used in the process of finishing boots and shoes by automatic appliances and is to
facilitate or better regulate the oscillating movement of the burnishing shaft and
rubbing block, and also to give a uniform pressure on the rubbing block while at any
angle during the burnishing of the heel, an easy and noiseless movement being
given to the machine by the several mechanical arrangements hereinafter described
and illustrated in the sheet of drawings accompanying this Specification to which
we will now refer.
Figure 1. is a side elevation of the machine proper, the parts for which we claim
in this invention are denoted by an X after the letters of reference.
Figure 2. is a view of the mechanism whereby we obtain the oscillating movement
to the burnishing shaft.
It will be found that the same letters of reference refer to like parts in all the
figures.

short shaft D, upon which are placed the fast and loose pulleys E and F and fly.
wheel F the inner end of the said shaft carrying the crank disc G* provided with
a balance projection or plate y¹x, to this disc is pivoted the vertical rack bar H*
having teeth on one face gearing with the tooth wheel I* in the rocking guide J* to
impart a uniform oscillating movement to the burnishing shaft M. The gas for
heating the burnishing block is conveyed through the hollow shalt M from the pipe N.
and delivered through a small pipe to the burnisher at n'. The spring n² keeps the
said block to the heel of the boot during the burnishing process, the lever L, which
carries the burnisher is tensioned by the circular spring Ox. The sliding bracket P
carries the jack p. which works in the screwed boss p¹× when by the operator
depressing the handle p the jack is moved forward and the boot Q being placed
thereon the heel is brought against the buffer immediately under the burnisher K,
and held in this position until the heel is polished, by depressing the foot treadle R,
the bracket P. is raised to bring the heel relatively to the burnishing block K.
When the burnishing operation is completed the boot or shoe is brought away from
the burnisher by releasing the foot treadle and moving the sliding bracket. P outward
in the holder S.
By tensioning the burnishing block K with the springs n²* and ox any shaped heel
can be operated upon, including heels known as "Wurtemburg heels" the upper
part of which is difficult to polish owing to the strong curve. By tensioning the

page_text: heated oscillating tool in the manner described pressure is brought to bear equally to
all parts of the heel, the steel spring O* attached to the compensating forked lever L
allows of a uniform tension being given to the burnishing arm, the said lever is acted
upon by the rising and falling of the burnishing arm and a regulated pressure is
kept upon the heel of a boot and shoe during the burnishing process.
In ordinary automatic heel burnishing machines the burnishing shaft derives its
oscillating motion by a tooth wheel gearing with a quadrant carried on a central pin,
the angle piece being attached to an eccentric fitted to the driving shaft these
machines are known as "Tapleys Heel burnishing machines" but having to he
driven at a great speed, this device constantly loses power and breaks near the centre,
or axle box of the quadrant, the lower portion or angle piece moving obliquely the
strain is too great upon it, and it becomes broken, and a fresh one has to take its
place. The tension to the rising and falling of the burnishing arm is now obtained
by a blade spring coming under the burnishing device consequently the upper part
of the heel cannot be reached to be properly burnished.
-
By the improvements hereinbefore described we get a regular oscillating move-
ment to the burnishing shaft carrying the burnishing tool, and a uniform pressure on
the rubbing block at varying angles during the burnishing of the heels of boots or
shoes.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
In a heel burnishing machine of the character described the combination of a
crank disc G and balance plate glx with the vertical rack bar H and rocking
guide J to impart the oscillating motion to the burnishing shaft M. and the burnishing
tool tensioned by the springs 12× and o× and operated in the manner substantially as
described and set forth.
