Improvements in Heel Burnishing Machines.
We, JOSIAH MENTOR GIMSON, JOSIAH GIMSON, ARTHUR JAMES GIMSON
and SYDNEY ANSELL GIMSON of the firm of Gimson and Company of the Engine
Works Vulcan Street, Leicester, in the County of Leicester, Engineers, do hereby
declare the nature of this invention to be as follows :-
This invention relates to improvements in heel burnishing machines in which we
provide contrivances that by their combination will greatly facilitate the process of
automatically burnishing the heels of boots and shoes by effecting a vertical and
horizontal movement of the jack, or a lifting and "to and fro" motion imparted to
the jack relatively to the burnishing tool, the jack being adjusted and lifted
vertically by the usual means, but the horizontal adjustment; and vertical
regulation of the cam sliding plate hereinafter specified to produce the desired.
result, and the means employed for securing the jack when in operative position are
hereinafter described.
For the purpose of our invention we may employ the machine forming the subject
of our prior Patent No. 7304 of 1888, or apply our improvements to any other
machines of a like character.
The object of this our invention is to provide mechanical means to cause the jack
automatically to move in the directions indicated relatively to the oscillating
burnishing tool during its movement from breast to breast of the heel so that it will
follow all inequalities or varying heights of the radial surface of the heel of a boot
or shoe during the burnishing operation, such being accomplished by the aid of a
grooved sliding plate, the curved groove of which varies according to, or may be
made adjustable to better conform to the circumferential curvature of the heels to
be burnished in order that the pressure of the tool may remain the requisite time,
upon any part of the heel from the top to the seat thereof. This is accomplished
in the following manner, a worm shaft is carried through the column or standard
of the machine on end of which is a drag link connected to crank pin on crank disc
on end of driving shaft or other suitable contrivances arranged, or employed to
oscillate the tool shaft, the worm gearing with a toothed wheel on shaft at right
angles thereto, the outer extremity of which carries a cam of any suitable shape, to
the face of which is secured excentrically a rod, the upper end of which is attached
to a block on the cam plate fitting in slides attached to the side of the column,
this block is carried on a screw and hand wheel, by moving which the cam plate can
be adjusted vertically to shorten or lengthen the longitudinal movement of the jack,
an angular groove is made in the cam plate which receives a roller on end of
connecting lever ordinarily employed in such machines by this arrangement when
the jack is pushed up its slide so that the heel of the boot thereon comes up under
the burnishing tool to be burnished, a pin on the said jack engages a slot in the
said lever and holds it in position, when the burnishing operation is finished upon
the handle of the lever being raised the jack will fall away, or can be pulled
outward thus liberating the heel from under the burnisher. Under the cam before
mentioned is a roller on end of a rod and levers operated upon by the rotation of
the cam shaft to cause the vertical lifting of the jack, as usually employed for such
purpose, or other mechanical means that are well known for lifting the jack may be
employed in connection with the cam plate arranged as before described. The
vertical adjustment of the jack is also carried out by a hand wheel on the rod
thereof as usual.
We also provide in heel burnishing machines such as shown in our prior Patent
before alluded to, or in other machines having a jack carried in a sliding bracket

page_text: under the oscillating burnishing tool either by hand by bringing down a hand lever,
or automatically; a spring secured to the bracket adapted to hold the said handle
firm when brought down thus keeping the boot heel and jack from moving
sideways, the said handle being released by compressing the spring.
By the combined movements of the jack in the manner described we are enabled
to get an equal pressure to the heel relatively to the oscillating burnishing tool.
The groove.in the cam plate can be made to any angle desired, or we can employ
a series of plates for one machine and adjust the same to the different widths of heel
to be operated upon.

COMPLETE SPECIFICATION.
Improvements in Heel Burnishing Machines.
We, JOSIAH MENTOR GIMSON, JOSIAH GIMSON, ARTHUR JAMES GIMSON
and SYDNEY ANSELL GIMSON of the firm of Gimson and Company of the Engine
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 relates to improvements in heel burnishing machines in which we
provide contrivances that by their combination will greatly facilitate the process of
automatically burnishing the heel of boots and shoes by effecting a vertical and
horizontal movement of the jack, or a lifting, and a "to and fro " motion impartel
to the jack relatively to the burnishing tool, the jack being adjusted and lifted
vertically by the usual means hereinafter explained, but the horizontal adjustment
and the vertical regulation of the cam and sliding plate hereinafter specified to
produce the desired result, and the means employed for securing the jack when in
operative position from moving sideways are herein illustrated and described. For
the purpose of our invention we may employ the machine forming. the subject of
our prior Patent No. 7304 of 1888, or apply our improvements to other type of
"Tapley
or any other machine of a like character, as shown in the sheet
of drawings annexed in which, Figure 1 is a side elevation and Figure 2 an end.
clevation partly in section through the column of the machine showing the slide and
its connections. We have referred to those parts of the said machine which forms
the subject of this invention by figures of reference, and to others by letters, while
the cam and levers usually employed for lifting the jack we have not illustrated.
The object of this present invention is to provide mechanical means to cause the
jack A to move automatically in the direction indicated relatively to the oscillating
burnishing tool during its movement from breast to breast of the heel so that it will
follow all inequalities or varying heights of the radial surface of the heel of the
boot or shoe B during the burnishing operation, such being accomplished by the aid
of a grooved sliding plate 1, the curved groove 2 or slot of which varies according
to, or may be made adjustable to better conform to the circumferential curvature
of the heels to be burnished in order that the pressure of the tool C may remain
the requisite time upon any part of the heel from the top to the seat thereof.
This is accomplished in the following manner, a worm shaft D, is carried through
the column or standard of the machine, on end of which is the crank arm E
connected to crank pin F, G, on the disc H, on end of driving shaft. Or by other
suitable contrivances arranged, or employed to oscillate the tool shaft, the worm d
gears with the toothed wheel d¹, on shaft d², the outer extremity of which carries
the cam or block 3, of any suitable shape so that it clears the bottom of the sliding
plate 1, as the block revolves; to the face of the adjustable block 3*, is secured

page_text: the lower end of the rod 4, the said block being capable of regulation to alter the
length of stroke and the centre thereof by shifting the screw 5, to one or other of
the holes 6, in the block; the upper end of the rod 4 is attached to the block 7 on
the cam plate at 8, which fits in the slides 9, secured to the side of the column, the
block 7 is carried on the screw 10, having the hand wheel at top 11, by moving
which the cam plate 1 can be adjusted vertically to shorten or lengthen the longi-
tudinal movement of the jack A, the angular groove 2 in the cam plate receives
the roller 12, on the connecting lever 13, by this arrangement when the jack has
been pushed along the slide I, so that the heel of the boot thereon comes under the
burnishing tool c, to be burnished, a pin J.on the jack engages a slot K in the said
lever and thus holds the jack firm, when the burnishing operation is finished by
lifting the handle of the lever clear of the said pin the jack will fall away and slide
back again to liberate the heel from under the burnisher. To secure the vertical
lifting of the jack, under a cam operated by the rotation of the cam shaft d², is a
roller on end of a rod and levers connected to the jack post not shown but usually
employed for this purpose, or other well known mechanical means may be employed
in connection, and in combination with the cam plate arranged and operated as
above described.
The vertical adjustment of the jack A is carried out as usual by the hand
wheel L.
We also provide in machines of the character hereinbefore described a contrivance
to hold the handle when down so that the boot heel is kept from moving sideways
which consists of the spring 14, or may be catch secured to the jack A, the said
handle being easily released by compressing the front of the spring or lifting a latch
or catch.
By the movements of the jack in the manner described in relation to the
oscillating burnisher tool we are enabled to get an equal pressure on all parts of the
heel.
It will be well understood that the groove, or inclined slot in the cam plate 1,
may be varied to any desired extent, or we can employ a series of plates in one
slide, and alter the shape or incline of the slot, and adjust the same to the different
widths of heel it is desired to operate upon.
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 :-
1. In a boot or shoe heel burnishing machine the combination with a movable
jack and means for lifting the same, of a grooved sliding plate, or plates, a rod
connected to it and to regulating block in grooved cam on cross shaft, revolved
from worm shaft, adjusting screw and hand wheel, a roller working in inclined slot
in sliding plate from rod connected to jack. To obtain a regulated "to and fro "
motion of the jack in presenting the heel to the burnisher tool, and spring or catch
for holding the handle down and preventing the boot heel from moving sideways.
Substantially in the manner and for the purpose as hereinbefore described.
Dated this 26th day of April 1892.
