Improvements in or relating to Boot or Shoe Heel Burnishing
Machines.
We, JOSIAH MENTOR GIMSON, JOSIAH GIMSON, ARTHUR JAMES GIMSON
and SYDNEY ANSELL GIMSON of the firm of Gimson and Company 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 has reference to improvements in or relating to boot or shoe
heel burnishing machines of the "Tapley" or other similar type, and consists in
providing facilities for increasing the out put of such machines, and also to better
regulate the pressure of the oscillating burnishing tool in rubbing or polishing
the sides or breast to breast of the heel and further regulate the pressure exerted
by the burnishing tool upon all parts of the heel so that no matter what curve
or at what pitch the heel is to be burnished, we can concentrate the pressure
thereon, or reduce or enlarge such pressure at will. This part of our invention is
an outcome of our former Patent No. 7304 of 1888-referring to the spring n*
and tensioning of the burnishing block K mentioned therein. We also cause the
automatically lifting or raising of the jack frame, or obtaining a regulated lifting
of the jack so that it will rise and present the heel in all its varying inequalities
equally on all parts to the vibrating burnishing tool. Such lifting or raising of the
We attach to a
jack carrying the boot is accomplished in the following manner.
slide (or slide rod connected or studded thereto) working either vertically or
horizontally to suit the construction of the machine, in suitable guide brackets
and having a locking lever thereto removable from the jack when it is desired to
disconnect the automatic gear a rod the inner face of which is tapered or has an
inclined surface, the lower end fitting in a steadying bracket, this rod comes in
contact with the roller end of a sliding bar passed through slots in the column or
pillar of the machine. Its other end being linked to a vertical pivoted lever, the
lower end of which also carrying a roller rides upon the tapered face or incline
of a movable series of conformable shaped surfaced cams or inclines adapted to
be turned under such bearing roller to correspond with the shape of the heel
upon the jack to be operated upon. These inclines all on one base are loosely
mounted on a pin, and made firm in the position desired by aid of a spring pressing
against it, such pin being upon the end of a lever connected to a cross shaft carrying
the lifting levers which come under the lower end or trunnions of the jack frame
rod. When the incline bar or rod moves with the slide before mentioned the
sliding bar is pressed back or moves forward causing the roller on the lower end
of the pivoted lever to move in the opposite direction up or down the face of one
of the shaped, curved or tapered inclines, set at the top, and thus gradually and at
the proper time raising the jack frame, the same falling again by its own weight.
To properly regulate the pressure upon the sides or from breast to breast of the
heel during the rubbing or polishing operation we make a bracket and fit it upon
the top of one of the bearings of the tool carrying shaft, the holes in the bracket,
or in a bush placed therein being internally screw threaded to receive an externally
screw threaded rod carrying a milled headed or other suitable hand wheel or lever,
the inner end of this rod being connected to an inclined adjustable plate its forked
sides fitting over the tool carrying shaft. Upon the face of this adjustable plate
rides a roller fitted in the centre of a loosely fitted bracket adapted to carry near
each end upon pins or other suitable projections open springs placed in holes in
the burnishing counterbalance block, both these springs act at one time to the

page_text: passing of the roller on the inclined plate at the time the tool is passing over the
side or breast to breast of the heel. The inclined plate is moved to the angle
desired by the operator turning the hand wheel, or lever. The said open springs
can be further operated upon when desired to regulate the pressure exerted by the
burnishing tool upon the heel by set screws put through the opposite side of
the burnishing or tool balance block, and pressing on the inside lower ends of the
springs.
To increase the out put of such machines we arrange in a suitable guiding bracket
on binge or upon spindles working in bearings or by other equivalent means, two or
more right angle jacks, or jacks at acute or obtuse angles-one of which will be under
the burnishing tool for the operation, after having had the boot previously clamped
in position by any well known way-while the other will have been brought down
out of the way and the boot removed therefrom, and another will take its place.
When one of the angled jacks is brought from under the burnishing tool after the
burnishing or polishing operation has been performed for another to be put there
under, it drops upon, or on to a rubber or other like concussion pad or pads,
projecting from the guide bracket or slide casting or arms of the jacks.

We, JOSIAH MENTOR GIMSON, JOSIAH GIMSON, ARTHUR JAMES GIMSON,
and SYDNEY ANSELL GIMSON, of the firm of Gimson and Company 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 has reference to improvements in or relating to boot or shoe heel
burnishing machines of the "Tapley or other similar type and consists in the
first part of providing facilities to better regulate the pressure of the oscillating
burnishing tool in rubbing or polishing the sides or breast to breast of the heel and
further regulate the pressure exerted by the burnishing tool upon all parts of the
heel so that no matter what curve, or at what pitch the heel is to be burnished, we
can concentrate the pressure thereon, or reduce or enlarge such pressure at will.
This part of our invention is an outcome of our former Patent No. 7304 of 1888,
referring to the spring n²x and ox, and the tensioning of the burnishing block K
mentioned therein. We also cause the automatically lifting or raising of the jack
frame, by obtaining a regulated lifting of the jack so that it will rise and present
the heel in all its varying inequalities equally on all parts to the vibrating
burnishing tool.
That our invention may be well understood drawings are annexed in which:
Figure 1. is a side elevation of the machine.
Figure 2. an end elevation with jack removed.
Figure 3. is a plan of the balance block or weight K and
Figure 4 a front view of the conformable shaped surfaced cams or inclines
hereinafter described.
In carrying out that part of our invention as relating to the lifting or raising
of the jack in presenting the boot or shoe heel to the oscillating tool we attach to
the slide A, a bar A' in any suitable manner; to work vertically or horizontally
according to the construction of the machine; in rear of the said slide, and through
the bracket B. is the rod C' to which is attached the hand lever C, so that when it
is desired to disconnect the automatic gear as in our former Patent No. 12862 of
1891, the operator can release the hand lever C. by removing it from the stud C

page_text: on the jack. The inner face of the bar or rod A' is tapered or has an inclined
surface a¹; and the rod works to the roller a² in the bracket a³ the inclined surface
of the rod in its movement coming in contact with the roller D in the end of the
sliding bar E passing through slots E¹ in the column or pillar of the machine. The
opposite end of the bar E being linked to the vertical pivoted lever F, which
carries at its lower end a roller f¹ to ride upon one of the series of tapered or
moulded faces of the inclines f², f³, ff, which are conformably shaped, to form
a cam surface or incline, on one mould or base G to the contour or shape of the
heels to be operated upon.. The cams G are placed upon a pin g', in the outer end
of the lever G¹, the inner end of which is keyed to the shaft 92 carrying the lifting
levers, under the lower end or trunnions 2, of the jack frame rod. In the
back of the said cams G are holes f, ƒ ƒ and ƒ each of which fit upon a pin 10
projecting from the lever G. In order to change the inclines or cams G. to bring
the one incline corresponding with the shape of the heel on the jack under the
bearing roller, they are pulled out clear of the pin 10, turned, then released when
they are held secure by the spring G2 pressing thereon. When the tapered rod or
incline A¹ moves with the slide before mentioned, the sliding bar E is gradually
pressed back, or moves forward when the roller f¹ on the lower end of the pivoted
lever F is caused to move in the opposite direction, up or down the face of one of
the shaped, curved or tapered inclines, or cams G, and thus gradually and at the
proper time raising the jack frame, the same falling again each time by its own
weight. In order to regulate the pressure upon the sides or from breast to breast
of the heel during the rubbing or polishing operation we fix or form a bracket H
on the top of one of the bearings of the tool carrying shaft, the hole in such bracket
or in a bush placed therein being internally screw threaded to receive the externally
screw threaded rod h, provided with millheaded screw or hand wheel h¹, or lever if
so desired. The inner end of the rod h impinges against, or is connected to the
adjustable plate h³ loosely fitting on the tool carrying shaft . Upon the outer
dished face of the plate 3 rides a roller ' fitted in the centre of the pivoted
bracket I adapted to carry near each end upon pins ¹, open springs ², fitting in
holes, in the counter balance weight K, both these springs act at one time to the
passing of the roller ', on the inclined plate h³, at the time the burnishing tool at
the inner end of the tool holder is passing over the side and from breast to breast
of the heel, the plate 3 being moved to the angle desired by the operator turning
the hand wheel hº. The said open springs can be further operated upon if
desirable to regulate the pressure exerted by the burnishing tool upon the heel of
the boot or shoe, by the set screws it, on the threaded ends of the pins on the
opposite side of the counter balance weight or block K, and seen in the detailed
view given in Figure 3. The bracket I, is connected to the burnisher levers by
by spring ox. The operation of the machine is as follows: When the operator
has seen to the movable inclines or cams on the block G, so that the shape shall
correspond with the pitch of the heel, and fixed the boot or shoe upon the jack and
moved it under the burnishing iron, then securing the locking lever C, and seen to
the pressure regulating device the oscillating tool will move about the heel, while
the jack is moved longitudinally and raised or lowered at the right time, in
presenting the heel to the herein described regulated pressure of the burnishing
tool.
Having now particularly described and ascertained the nature of this invention
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 the slide A
of a tapered bar or rod A', sliding bar E, pivoted lever F, the conformably shaped
cams or inclines on the mould or block G for lifting the jack to the height desired
to properly present the heel to the burnishing tool. Substantially as described.
2. A series of conformable shaped surfaced cams or inclines f f f f corre-
sponding to the shape or contour of the heels of boots and shoes, in the operation of

page_text: raising the jack to the various heights desired in presenting the heel to the
barnishing tool. Substantially as described.
3. In a boot or shoe heel burnishing tool holder and its shaft, the combination of
the plate and adjustable screw h, carried in bracket H, the loosely pivoted
bracket I, connected to tool holder by spring ox, and pins i carrying the springs ²
and screw nuts, all for the purpose. Substantially as herein before described.
4. In boot or shoe heel burnishing machine the combination of the herein before
mentioned devices for raising the jack and equalizing the pressure of the burnishing
tool upon the surface of the heel in all its inequalities. Substantially as herein
described and set forth.
