Improvements in and Apparatus for Securing Renewable Metallic
Wearing Surfaces to the Soles and Heels of Boots; Shoes; and
other Coverings for the Feet.
I RALPH RAWLING MADDISON of No. 27 Tune Street Barnsley, in the County
of York Commercial Clerk, do hereby declare the nature of this invention' to be as
follows:
The object of my invention is to manufacture the soles and heels of boots, shoes,
and other coverings for the feet in such a manner as shall not only render them
very durable, but very easily and very quickly renewed at or on their wearing
Burfaces by any intelligent adult person.
The essential features of my invention are embodied, or consist, in a special
construction of screw, after the manner or fashion of what are known to ironmongers
as "strap.screws or analogous screws.
ני
According to my invention I make holes for the reception of my protectors in'
the material of which soles and heels.are made at those parts which are usually
most exposed to wear in use. And having made provision for preventing the
female portion of the screws from turning axially (after being forced home into
their seats) I force them tightly into the holes prepared for them. I then sorew
the male or wearing part of the screw (which may be circular' in plan view, or
other convenient form) into its place, and attach the sole or heel to the boot for
which it is intended.
The head of the male screw part of my device is that which is exposed to wear
in use. I allow it to wear until it is so thin as to be easily turned up in such a
mauner that
a pair of pincers may be used in unscrewing it from its socket--which
is thus rendered available for holding a new wearing surface.

I designate, my invention "Screw Socket Boot Protectors" because that term
aptly describes its most essential features.

I Ralph Rawling MADDISON of 218 Sheffield Road (late of No. 27 Tune
Street) Barnsley, in the County of York, Commercial Clerk 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
My invention relates to a form of boot protector which is easily, quickly, and
noiselessly renewed, at those parts of the sole and heel which are most exposed to
wear in use, and consists in certain novel details of construction as hereinafter fully
set forth, the object being to produce a more effective and otherwise desirable article
cof this character, than is now in ordinary use.
In order that my invention may be fully understood I desire to direct attention to
the accompanying drawings, illustrative thereof (the same letters of reference

page_text: being used to designate the same parts throughout the several representations) in
which :-
Referring to Sheet 1
Figure 1 represents a side elevation of a portion of a boot, the sole and heel
of which have vertical transverse sections of two forms of my protector in them, viz.,
those with regular (i.e. round) heads, and those with irregularly shaped heads.
The latter being designed for placing in those positions where the wear is
exceptionally great.
Figure 2 represents a plan of the same.
Figure 3 represents a side elevation of a protector of regular form, the head of
which is designed to fit into, and hold in its proper place, the head of an irregularly
shaped protector.
In Figure 4 (which is partly in section) is represented a retaining socket with
a star-like head, tho rays of which are imbedded in the sole to prevent it turning
on its axis. In Figure 4 may also be seen a hole, through the centre of the shank,
for the reception of a pointed steel pin of triangular or polygonal section, which
on being driven into it, after the head is worn-out, will serve as a means of
unscrewing the shank from the retaining socket, in order that a new one may be
placed in its stead. In Figure 4, too, may be clearly seen that the shank is
swollen at its junction with the head, so that the head is thereby more securely
united to it.
A, represents regular (i.e. round) headed protectors, that may be screwed
home with either an ordinary screw-driver, or with a pair of round nosed
pinchers.
B, represents protectors with irregularly formed heads (similar to the metallic
plates that are often fastened onto the heels and toes of the strongest boots) the
shanks C of which are preferably made stronger than the shanks E, of the smaller
protectors D, which serve to retain them in their proper positions.
F, represents notches or recesses in the periphery of the protectors that are
distinguished by the letter D; they are designed so that a key, or wrench, or
spanner, may (by means of pins with which it is provided for engaging with them)
be made to turn them either in or out of the retaining sockets. The notches that
are represented by F serve also for the reception of the heads of small nails, sprigs,
or screws, that may be driven into the sole for the purpose of preventing the
head D, when of unusually large diameter, turning on its axis; after it has been
screwed into its proper position; as will be readily understood without a more
explicit description.
G, in Figure 3, represents the bevelling. of the heads of the protectors that are
designated by the letters D, and that adapts them for fitting tightly into the
tapering holes and recesses (as shown, for instance, in dotted lines at H in Figure 1)
in the protectors designated by the letter B, thereby the more firmly holding B in
proper position.
The difficulty that would be created by my protectors in scraping dirt off the
soles of boots, may be obviated by the use of a layer of some such cement as that
known as Prout's Elastic Glue (well known to bootmakers) or any other cement
that can be readily applied to filling up the space between the protectors, and for
renewing it from time to time.
Referring to Sheet 2 Figures 5 and 6 represent a form of protector, the socket
of which is designed to be screwed into its position in the sole of the boot et cætera,
and to have the outer head screwed into it in the contrary direction, so that there
shall be a tendency for the two screws to combine in clasping the sole when the
wearing portion of the protector is screwed into position. Figures 7 and 8 represent
an alternative form in which this end is attained. Figures 9 and 10 represent
another alternative form in which this end is attained. And Figures 11 and 12-
represent yet another alternative form in which this end may be attained. These
all are on an enlarged scale.
Referring to Sheet 3 Figures 13 and 14 and 15 represent a form of head for:
1
.

page_text: irregularly shaped protectors that is specially designed to provide for that very
great amount of wear that results from the first impact of the boot et cætera with
the ground through the heel.
In Figure 16 (which is on an enlarged scale) is delineated the socket or retaining
portion of a protector that may be used without any flange, by making on, and
round, the circumferance a male screw thread, formed for cutting into, or bedding
itself in, the sole of the boot et cætera. These sockets are thus fitted for being
used from the outside of the boot. This is accomplished by first screwing the
shank of the head, or wearing portion into its place; and then using it as a means
for screwing the socket into position in a hole in the sole. Thus is secured the
additional advantage, that should the interior, or female thread of a socket "become
so worn by use as to be no longer available for holding a head in position, it may
be replaced by a new one. It can be unscrewed from its position in the sole by a
pair of pinchers, with the aid of a steel drift or pin of triangular or polygonal
section as has already been described with reference to Figure 4. There may
of course be a head on the outside of the socket, in contact with the wearing head,,
or protector.
Figures 17 and 18 are also on an enlarged scale. They are simply designed to
indicate that the socket of a protector may be made of triangular or polygonal
section, and tapered, and with little or no head, thus being retained in position,
and without the possibility of turning round.
The material of which my protectors are to be made, may be any suitable metal
or combination of metals; but preferably all forms of iron and steel for general use,
and brass, or copper, or other non-corrosive material for ladies and others
preferring them. They may too be made of various sizes and thicknesses to suit
various requirements.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
1. The grasping the soles of boots et cætera by a metallic screw, or screws, (after
the fashion of strap screws) so that the heads thereof serve as wearing surfaces,
firmly held in position, and easily and quickly replaced.
2. The strengthening the junction of the shank and the head of a boot protector,
made in accordance with the previous claim, by swelling out, or tapering the shank,
so as to increase its area at its junction with the head which it carries. And
providing a recess in the socket, for the reception of the said swelling, when it is
screwed home, as illustrated in drawing distinguished as Figure 4.
3. In a boot protector designed to be held in its place by grasping the sole, after
the fashion of strap screws, the use of a socket having a left handed external
parallel screw for screwing into the sole of a boot &c., and an internal parallel
right handed screw thread within it for the reception of the external screw thread
of the shank of a head designed to serve as a boot protector, or the reverse
of this arrangement; as seen in Figures 5 and 6 respectively, on an enlarged
scale.
4. In a' boot protector designed to be held in its place by grasping the sole,
Bleft handed external
after the fashion of a strap screw, the use of a socket having
tapered screw for screwing into the sole of a boot et cælera, 'and an internal parallel
right handed screw thread within it for the reception of the external screw thread
of the parallel shank of a head designed to serve as a boot protector; or the
reverse of this arrangement. As seen in Figures 7 and 8 respectively, on an
enlarged scale.
5. In a boot protector designed to be held in its place by grasping the sole,
after the fashion of a strap screw, the use of a socket having a left handed external
parallel screw for screwing into the sole of a boot et cætera, and an internal tapered
right handed screw thread within it for the reception of the external screw thread
of the tapered shank of a head designed to serve as a boot protector; or the reverse

page_text: of this arrangement. As seen in Figures 9 and 10 respectively, on an enlarged
Bcale.
6. In a boot protector designed to be held in its place by grasping the sole after
the fashion of strap screws, the use of a socket having a right handed external
tapered screw for sorewing into the sole of a boot et celera, and an internal tapered
left handed screw thrond within it, for the reception of the external sorew thread.
of the tapered shank of a head, designed to serve as a boot protector; or the
reverse of this arrangement. As seen in Figures 11 and 12 respectively, on an
enlarged scale.
7. In a boot protector designed to grasp the sole, after the fashion of a strap
screw, having the head of the socket portion made star like, so that the rays
of the said star, being inibedded in the sole, will serve to prevent it turning on its
axis, when force is exerted to screw the male screw home into it.
8. In a boot protector designed to grasp the sole, after the fashion of a strap
screw, and to be so held in its place, having notches or recesses so made in the
periphery of the head, that a key may be made to engage with them, and so serve
to turn it when need so require.
9. In connection with boot protectors as described in the previous claim the use
of keys, or wrenches; so made as to fit into two, or more, or all the notches in the
periphery of the head described in claim numbered eight.
10. In a boot protector designed to grasp the sole, after the fashion of a strap
screw, having notches or recesses F so made in the periphery of the head that sprigs,
or small-nails, or screws, may be made to so engage with them as to prevent the
protector turning on its axis.
11. In boot protectors designed to grasp the sole after the fashion of a strap
screw, having the surface of their heads made without alots, and the periphery
without notches, or recesses, and turning them into, or out of, their seats or sockets
by the aid of pinchers.or pliers only.
12. In connection with the use of boot protectors designed after the fashion, of
strap screws, the use of pinchers or pliers made with circular noses, for the purpose
of fitting them so as to grasp them tightly, and turn them in or out of their seats
or sockets.
13. In a boot protector designed to be held in its place by grasping the sole after
the fashion of a strap screw, the arrangement of a combination of irregular heads,
(similar to such plates as are often fastened onto the heels and toes of the
strongest boots) along with regular (i.e. found) heads: the latter serving to keep
the former in position, as illustrated in drawings distinguished as Figures 1
and 2 at B.
14. In boot protectors designed to be held in place by grasping the sole, after
the fashion of a strap screw, so arranging a combination of irregularly shaped
heads along with regular (i.e. round) heads, that the heads of the latter being
tapered inwards, and downwards, shall more readily fit into and securely
fasten the former,, as illustrated in the drawing distinguished ns Figures and 3
at H and G.
15. In a boot protector designed to be held in its place by grasping the sole,
after the fashion of a strap-screw. Having a hole made (tube like) through the
shank and head, or through the shank only, so that an instrument of triangular or
polygonal section, on being forced into it, may, when need be, serve as a means
of unscrewing the shank from its seat, as illustrated in the drawing distinguished
as Figure 4.,
16. In a boot protector designed to be. held in position by grasping the sole,
after the fashion of a scrap screw, having the principle heel protector so placed at
an angle (or in other words, having it so bevelled from the outside at I in
Figures 13 and 15 of Sheet 3, to, or towards the retaining shank C) that it will
be very durable, more evenly worn (and consequently last longer) than has.
hitherto been usual with protectors for the heels of boots. As will be readily under-
stood on reference to Figures 13 and 14 and 15 of Sheet 3. The form of protector

page_text: claimed is most clearly shown in Figure 13 by having its section, which is along the
line from a tor in Figure 14 distinguished by crossed lines.
17. As a modification of claim number one, a replaceable boot protector,
designed to screw into and out of a tube, the latter having screw threads both
5 internally and externally; but without flanges or projections, the internal
screw being for the reception of the shank of the replaceable protector, and the
external screw being the means whereby it is forced into, and retained in, the .sole
of the boot.
18. In a boot protector designed to be held in its place by grasping the sole,
after the fashion of a strap screw, having that part of the shauk of the retaining
socket that is in contact with the sole made of triangular or polygonal section, so
that it is prevented from turning on its axis.
