Improvements in Protectors to the Soles and Heels of Boots and
Shoes, and Methods and Appliances for Affixing and Removing
the same.
We EDWIN HALL of 152 North End Road West Kensington in the County of
Middlesex Bootmaker and WILLIAM HALL of 25 Percy Street Leeds in the County
of York Bootmaker do hereby declare the nature of this invention to be as follows:-
In
Our Invention consists in providing protectors of suitable shapes and materials so
constructed and secured as to be readjustable without disturbing the structure of the
boot or shoe at little cost and trouble and without hammering and almost totally
obviating the necessity of the present expensive system of resoling and reheeling
boots and shoes. Our Invention consists of so constructing protectors for the soles
and heels of boots and shoes that they may be secured and attached to projecting screws
which are first firmly screwed into the soles and heels of the boot or shoe for the
purpose of receiving the protectors either by means of perforation through the
protector or by means of screwing the protectors on to the projecting screws.
cases where the protectors are perforated the protectors must be secured by nuts and
also washers where required or in any other suitable way so as to permit the protectors
being readily removed and replaced when required. In cases where the protectors
are not perforated and the material used for the protectors is not adapted for being
directly secured into the boot or shoe as aforesaid suitable wormed and tapped cavities
of metal or otherwise are sunk into the protectors or placed into them either by
casting or moulding for the purpose of receiving the screws and thus enable the
protectors to be screwed firmly to the soles or heels. By this means it is possible to
keep the soles and heels of boots and shoes in good repair by simply screwing and
unscrewing the protectors and replacing or providing new protectors where worn or
desirable.

Improvements in Protectors to the Soles and Heels of Boots and

We EDWIN HALL of 152 North End Road West Kensington in the County of
Middlesex Boot Manufacturer and WILLIAM HALL of 25 Percy Street Leeds in the
County of York Boot manufacturer 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 :-
:
The objects of our invention are, to provide protectors for the soles and heels of
boots shoes and clogs of suitable shapes and materials, so constructed and secured as
to be readjustable at little cost, without disturbing the structure of the boot or shoe
by hammering, and almost totally to obviate the present expensive system of repairing
the soles and heels of boots and shoes; the affixing and readjusting of the protectors
being capable of ready accomplishment by the wearer, without the assistance of
skilled labour.
The basic principle of this invention is, the application of what is hereinafter
described as The permanent projecting screw" upon which the protectors hereinafter
described, are in all cases affixed and secured.
"The permanent projecting screw, is a short screw, the length varying according to
the thickness of the sole to be operated upon and according to the depth of the
protector to be fixed thereupon. This screw is tapped at the one end as for wood,
and at the other for metal.
These two tappings to be in reverse directions i.e. one to be a left hand thread, and
the other to be a right hand thread.
The two tapping may be made in the same direction. A slit may be made at the
metal tapped end of the screw for the reception of a screw driver: but in cases where
the tappings are made in the same direction, this slit will be unnecessary as the screw
can then be driven into the sole, by means of the metal cap hereafter described.
Such screws are driven firmly into the bottoms of the soles and heels to the extent
of the wood thread. The metal tapped end is left projecting for the purpose of
receiving the protector, which protector is perforated to receive the screw.
The protectors may be shaped either as soles and top pieces of heels, or sections of
the same, or of other suitable shapes; the circular with central cavity may probably
be most generally adopted. See figure one.
The protectors are fastened to the soles and heels by means of the perforations
made in them to receive the " permanent projecting screws" or in other words, the
permanent projecting screws pass through holes in, the protectors, leaving the
metal tappings projecting in the cavities of the protectors. See figure 2.

The circular protectors may if preferred be sunk a little into the soles.
A brass or other cap is tapped with a screw orifice in a projecting central column,
which is surrounded by a saucer shaped ring.or depression. See figure three.

page_text: The metal cap is then tightly screwed down upon the projecting screw, so that it
has the effect of binding the protector tightly and firmly to the sole or beel. The
top of the metal cap is provided with two slits or two small holes, to receive a forked
driver.
It will generally be found desirable to have smaller protectors for the toes and
heels as shown in figure 4.
Protectors of the shapes of soles and heels or of sections of soles and heels or toe
pieces or heel plates are applied upon the same mechanical principle i.e. by means
of holes or perforations in the protector which are placed over the "permanent
projecting screw and then again screwed down by means of the metal cap,
counter sinking can be made in the protector, to protect the metal cap from
wear. See figure 5.
"
They may however be screwed down without counter-sinking by means of a
tapped nut or cap, which in such case would come in contact with the ground
in walking.
The holes or slits made in the tops of the metal caps for receiving screwdriver
should not penetrate through, but only partly through the metal, otherwise the
wet may penetrate to the screw, and create rust and thus prevent the protector
being readjusted readily.
Clog irons or other protectors for clogs can be affixed upon the principle of
this invention, and thus largely prevent the splitting of the wooden soles, by the
present method of nailing on the irons.
MATERIALS FOR PROTECTORS.
The materials of which these protectors in their variations can be made are
numerous, and will vary according to the kind of shoe, required to be fitted.
For the lighter work india rubber, gutta-percha, or similar clastic, or semi-elastic
material, will be adaptable, whilst for heavier work metal, or other solid materials,
may be employed.
Having now particularly described, and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is —
1. The combination of the "permanent projecting screws" as applied to the soles
and heels of boots shoes and clogs, with protectors of India rubber or other material,
screwed on or attached, substantially as described.
2. The protector as aforesaid, with the other variations in shape as defined in this
specification, and applied to the principle and purposes of this invention.
3. The metal cap with central column, and saucer shaped cavity as described, and
as applied to the purposes of this invention.
4. The tapped nut or cap of suitable shape and material for coming in contact with
the ground in walking, and applied to the permanent projecting screw aforesaid.
