AN IMPROVED ROTARY HEEL-PLATE FOR BOOTS AND SHOES
Year: 1888

page_text: Date of Application, 9th Feb., 1888
Specification Accepted, 9th Mar., 1888
We, WILLIAM FILLINGHAM, of the South Yorkshire Asylum, Wadsloy, near Sheffield,
in the County of York, Boot maker and ROBERT FILLINGHAM, of Grinley-on-the-Hill,
in the County of Nottingham, Boot Maker, do hereby declare the nature of our said
invention for "AN IMPROVED ROTARY HEEL-PLATE FOR BOOTS AND SHOES," to be as
follows:-
This invention relates to improvements in boot heels and consists of a rotary plate
working in a hollow cast metal frame. The said frame is cast to the shape of an
ordinary boot heel the upper or wearing surface having a circular sunk inlet extending
to the outside edge of the frame on the right and left sides and with a wider edge at
the back-side.
The side of the circular inlet is slightly bevelled and has a required number of
countersunk holes in the bottom of the inlet through which screws are passed to
secure the frame to boot heel.
In the centre of the inlet is a round hole to receive a screw for securing the
different parts hereinafter described. A triangular shaped hole is left at each corner
of the frame.
I next cast a circular ring fluted on the underside and flat on the surface having a
tubular centre piece connected to the ring by four or more countersunk bars, or the
space between the ring and centre part may be left solid and perforated to any
design. These bars are below the level of the ring and the centre part, and thinner
on the top side than on the bottom side. The sides of the said ring are bevelled
fitting into inlet in frame. A hole is bored through the centre to receive a screw.
The under side of the said ring passes. through the bottom of frame, and the ring
rests on an india-rubber or gutta-percha cushion. I then take a circular india-rubbor
cushion with a round hole in the centre having a thin convex rim outside the space
between rim and centre, having four or more raised portions which are separated by
grooves wider at the bottom than at the top to admit and cover the bars of the said
Auted ring.
Two triangular pieces of india-rubber or gutta-percha are fitted in the corresponding
holes in the frame.

page_text: In carrying this invention into effect the triangular india-rubber or gutta-porcha
cushions are placed in their respective holes and the frame is then secured to the boot
heel by means of screws or their equivalents. The circular india-rubber or gutta-
porcha cushion is then placed in the inlet on the wearing surface of the frame and the
metal ring forced into the grooves of the india-rubber cushion and the whole secured
by means of a centre screw.
Where gutta-percha is used it will be put into the inlet part of the frame hot, and
the ring pressed into its position, and when set the ends pared off level as required.
The advantage to be derived hereby is chiefly in the wearer being able to easily
reverse the wearing surface of the heel when one side has become worn, by simply
loosening the screw and turning round the ring.
The accompanying drawings illustrate our invention. The same letters of reference
apply to the different views.
Fig. 1, is a plan of the frame A shewing the inlet or countersunk portion B, also
the triangular corners C, C, the centro hole E together with counter sunk holes F.
Fig. 2 is a section through Y, Z, shewing the bevel G in the frame.
Fig. 3, is a plan showing the top of the frame A, with the triangular corners C,
bevelled to prevent the india-rubber corners from coming out.
Fig. 4, is a plan of the circular rim H shewing the bars I partly covered by the
india-rubber J and roughed to prevent slipping.
Fig. 5, is a plan of the circular rim H before being placed into the india rubber.
Fig. 6, is a section of the india-rubber in Fig. 4, showing the grooves K to receive
the bars I and having a convex rim L.
Fig. 7, is a section through A B of Fig. 5, shewing the fluting M running round
the underside of the rim also the centre hole N to receive a screw to secure every-
thing to the heel.
Fig. 8. is a plan of the plato complete.
Fig. 9, is a side elevation shewing the india rubber projecting below the heel plate.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner tho samo is to be performed we declare that what we
claim is :-
An improved heel plate for boots, shoes, and the like having a ring rotating therein
and fitting into an india-rubber cushion in the said plate the whole being secured to
the heel by means of a screw or its equivalent as hereinbefore described, and as
illustrated by accompanying drawings.
