PROVISIONAL SPECIFICATION.
Improvements in and Apparatus for Securing Metallic Wearing
Plates, Layers of Leather, India-rubber, Gutta-percha, or other
Wearing Material to the Soles and Heels of Boots, Shoes, and
other Coverings for the Feet.
I WILLIAM JONES of 143 Clopton Street, Hulme, Manchester, Painter, do hereby
declare the nature of my invention to be as follows:-
The object of this invention is so to secure a metallic wearing plate to the sole or
heel of a boot, shoe or other similar covering for the feet by means of a special
construction of screw that the said plate when worn shall be capable of easy removal
and so especially in the case of a heel plate can be reversed and the plate of one heel
when worn down on one side be exchanged for that of the other heel and thus the
durability of such heel plates are doubled. The same means of fastening being
applicable to securing metallic wearing plates or layers of leather, india-rubber,
gutta-percha or other suitable wearing material to the soles or heels of boots and
shoes and other similar articles with equal facilities of removing as aforesaid.
In performing my invention I employ a screw the head or top part of which is
flattened on opposite sides or made of a rectangular, oval or of any suitable shape in
cross-section, and which special shape is continued down to the screw thread so that
by means of such head the screw can be readily and firmly gripped by a pair of
plyers or other suitable tool however much the head may be worn and thus can be
unscrewed and removed with certainty and ease at any tinie.
•
When used for securing one or more thicknesses of leather, india-rubber, gutta-
percha or similar material of a soft and yielding nature I employ in conjunction with
the screw a clamping device, consisting of a metal counter-sunk head or washor of
broad area and the centre of which is bored or formed to receive the improved screw
head and thus I obtain a large clamping surface which renders it possible to secure
such material to the soles or heels of boots or shoes and to remove the same at will.

COMPLETE SPECIFICATION.
Improvements in and Apparatus for Securing Metallic Wearing
Plates, Layers of Leather, India-rubber, Gutta-percha, or other
Wearing Material to the Soles and Heels of Boots, Shoes, and
other Coverings for the Feet.
I WILLIAM JONES of 143 Clopton Street, Hulme, Manchester, Painter, do hereby
declare the nature of my invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
:
The object of this invention is so to secure a metallic wearing plate to the sole or
heel of a boot, shoe or other similar covering for the feet by means of a special
construction of screw that the said plate when worn shall be capable of easy removal
and so especially in the case of a heel plate can be reversed and the plate of one heel
when worn down on one side be exchanged for that of the other heel and thus the
durability of such heel plates are doubled. The same means of fastening being
applied to securing metallic wearing plates. or layers of leather, india-rubber, gutta
percha or other suitable wearing material to the soles or heels of boots and shoes and
other similar articles with equal facilities of removal as aforesaid.
On the accompanying drawing Fig. 1 represents the wearing surface of a boot or

page_text: .
shoe having wearing plates a a applied to the soles and a heel plate b applied to the
heel in accordance with my invention. Fig. 2 represents a plan view and Fig. 3 a
side sectional view of one of the wearing plates shewing also the screws in position
for securing the plate to the wearing surface as herein before described.
In performing my invention I employ a special construction of screw which
constitutes the essential feature of my improvements. This screw is illustrated by
front view Fig. 4 by side view Fig. 5 and by plan view Fig. 6 on the accompanying
drawing.
Instead of entirely filling the countersunk hole in the wearing plate as would be
the case with a wood screw the head or top part of my improved screw c is made of a
rectangular or square shape flattened on opposite sides (and which flattening is
continued down to the screw thread see Fig. 5) so that by means of such parallel flats
the screw can be readily and firmly gripped say by the points of a pair of plyers or
other like tool and thus such screw can be screwed home or can be unscrewed and
removed with certainty and ease at any time however much the heid thereof may be
worn.
The under side of the head is "coned" as illustrated in Fig. 4 to correspond with
the countersunk hole formed in the metallic wearing plate a.
In securing these plates to the sole or heel of a boot I simply place the plate in
position and bore the leather to start the screw and then by means of a pair of plyers
as aforesaid I turn the screw until it tightens against the countersunk hole in the
plate and thus I effectually clamp such plate to the sole or heel as the case may be
and with facility for easy removal as aforesaid.
In Fig. 7, I illustrate another form of heel plate designed to preserve the heel more
particularly at one side thereof.
When used for securing one or more thicknesses of leather, india-rubber, gutta-
percha or similar material of a soft and yielding nature and of any desired shape for
covering the whole or any part of a sole or heel of a boot or shoe-I employ a metal
by preference copper countersunk head or washer of broad area-as illustrated by
plan view in Fig. 8 and by sectional view in Fig. 9 and the centre of which washer is
bored out or formed to receive the improved screw head and thus by means of such
countersunk washers 1 obtain a large clamping surface which renders it possible to
secure such wearing material as aforesaid to the soles or heels of boots or shoes and
to remove the same at will.
In Fig. 10 I illustrate a plan view and in Fig. 11 a side sectional view of a wearing
plate shewing a pair of the countersunk washers d in position ready to receive the
screws c. Besides being used for securing plates or pieces of wearing material as
hereinbefore described this system of fastening is equally applicable to securing the
whole or any part of the sole or heel of a boot or shoe to the inner sole..
I do not confine myself to the positions indicated nor to the form of wearing
plates illustrated on the drawings as the same may be varied without departing from
my invention.
Having thus particularly discribed and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1st. The improved screw arranged with specially formed head and adapted to be
turned by a pair of plyers substantially as and for the purposes hereinbefore described
and illustrated on the accompanying drawing.
2nd. In the securing of metallic plates or other wearing material to the soles or
heals of boots or shoes the employment of the special construction of screw or screw
and countersunk head or washer substantially as herein before described and illustrated
on the accompanying drawing.
