Improved Interchangeable Protector for Boots and Shoes.
We, ALBERT POWELL, of 79 Reather Street, Oldham Road, Manchester, in the
County of Lancaster, Engineer, and HENRY LYNCH, of 19 Dale Street, Hulme,
Manchester, aforesaid, Agent, do hereby declare the nature of this invention and in
what manner, the same is to be performed, to be particularly described and asçer-
tained in and by the following statement:-
This invention is designed to provide a tip or protector plate for the heels or
soles of boots and shoes the wearing parts of which can be changed or removed and
replaced without taking off or renewing the whole plate.
It consists essentially of a frame plate or tip to be firmly attached to the heel or
sole of the boot provided with loose removable protectors or pieces which slide into
dovetail or other grooves on the outer surface of the fixed frame plate. It will be
fully described with reference to the accompanying drawings in which as an
example the invention is shown in several forms as applied to the heel of a boot.

Fig. 2. Plan of protector.
Fig. 3. Section on line - Fig. 2.
Fig. 4. Plan of protector modified form.
Fig. 5. Section on line y-y Fig. 4.
Fig. 6. Section on line - Fig. 4.
Fig. 7. Plan of another modification.
Fig. 8. Section on line u-u Fig. 7.
Fig. 9. Section on line v-v Fig. 7.
Fig. 10. Section on line w-w Fig. 7.
The frame plate or tip A. which is affixed to the heel is formed with grooves on
its outer surface to receive removable or interchangeable plates B. The frame
plate or tip A is preferably made of metal-iron or brass-but may if desired be
made of a softer or lighter material and the protector plates B are preferably made
of steel, though they may be made of rubber gutta. percha or other suitable
material.

page_text: The grooves into which the protector plates B slide are preferably dovetailed
as shown and the edges of the protector plates are made of a corresponding inclined
shape so as to slide thereinto and be prevented falling out.
Referring to Figs. 1 and 3 the frame plate A is shown with the grooves formed
by projections a cast thereon and it is fitted with three of the removable protector
plates B which slide into the grooves b. The protector plates B can easily be
removed when worn down and changed or others substituted therefor.
Referring to Figs. 4-6 the grooves in the frame plate or tip A to receive the
protector plates B and formed by small projecting pieces a riveted or otherwise
attached to the frame plate. In these figs. the protector plates B are shown all of
the same size and shape so that one pattern of protector can be fitted into any of
the grooves.
Referring to Figs. 7--10 a frame plate is shown constructed in a similar manner
. to that described in Fig. 4 the grooves being formed by the projecting pieces a¹
riveted on but provided with only two protector plates one at each side. In this
case the two protector plates are the same size but right and left hand..
The protectors B may be made with spikes to serve as cricket spikes or ice clips.
Or when the frame plate A is made as in Fig. 2 it will serve as a spur box the end
of the spur being made to fit into the groove b.
Instead of the grooves being formed of pieces projecting on the front surface of
the frame plate A they could be made indented into it with corresponding projecting
dovetail piece on the inner surface of the protector plate B.
The frame plate or tip A is affixed to the boot or shoe by screws or pins passing
through the holes e or by other means and it will be understood that the frame
plate or tip may be of any size or shape to fit different sizes or shapes of boots or
shoes or positions thereon.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. A protector for the heels or soles of boots and shoes consisting of a frame
plate or tip provided with grooves to be affixed thereto and removable or inter-
changeable protector plates which fit into the grooves substantially as and for the
purpose described.
2. An interchangeable protector for boots and shoes having the several parts:
constructed and arranged substantially as described with reference to the drawings
Figs. 1 to 3, Figs. 4 to 6 or Figs. 7 to 10.
