HARRY FREDERICK HILL Brassfounder Sherwood Street Nottingham HENRY
HILL Brassfounder Sherwood Street Nottingham, do hereby declare the nature of
this invention to be as follows:-
This invention consists of making adjustable wearing parts, for soles & heels for
boots & shoes, & may be made in one piece to cover the whole surface or in small
pieces as deemed convenient. These wearing parts are chiefly composed of india
rubber or composition or other suitable material with metal cylets or may be made
of metal only.
One form of this invention consists of metal eylets with a thread inside the hole
these cylets, are fixed permanently into the sole. A screw with a metal washer is
then screwed into the eylet. In some cases the washer is dispensed with & the
screw head enlarged & the nick of the screw cut down into the shank of the screw
to facilitate their removal. In some cases the screw heads may be covered with
rubber or other suitable material, & may be made hollow & filled in with common
Hint or like material & Portland & other cement that will set with water, or other
cheap, hard cement, or these screw heads & also the heel wearing pieces may be
filled in with rubber or other flexible material, and hard parts which may be of
iron. Another form consists of making coverings upon this principle to cover the
whole sole, & made of a foundation of sheet metal punctured up into spikes or
roughed surfaces with or without a rim round the edge & are filled up with papier-
machic or wood-pulp & hemp mixed with a glutinous substance, or may be hemp
& a glutinous substance only subjected to pressure. These soles may also be made
with a canvas foundation & fixed upon moveable or permanent springs or
strips of
metal or other suitable material, these flat strips being spring or screwed under a
rim which is attached around the edges of the sole, this rim may also be made
detachable at one side if desired; strips of leather small pieces or whole soles may
have sheet metal attached by the punctured spikes or sprigged from behind the
sheet metal for attaching to the rims. These special soles may also be attached by
eylets & screws. Metal plates with projections for allowing the screw heads to
sink below the plane of the plate are combined with screws & eylets. Plates or
protectors are also attached to the sole by means of projections or eylets which are
passed through holes punched into the sole & are secured by a rod or wire passing
between the inner & outer sole & through the holes in the eylets. These
protectors may also be formed by bending wire into the desired form & secured by
the before mentioned rods which may be screwed or plain. These wire wearing
parts may also cover the whole sole & be attached by rims or screws or by sprigs.
These wires are bent so as to give an alternate bend & open end which makes them
very pliable. In cases where the screw heads are covered they may be stretched
over a projecting head into a groove & tied on by thin cord or wire or otherwise or
simply stretched over. Rubber plugs may also be pressed into bevelled or grooved
erlets let into the sole & may have metal springs inserted in the rubber to secure
them thereto, or projecting bars or catches which fit into slots or holes made in the
eylets may secure them.
The soles
The cylets are split in some cases to give accomodation to the screw.
may also be formed with a piece of corrugated perforated sheet metal with eylets
upon one side & filled up with composition & also by a perforated plate which is
fitted over studs of metal, leather or the improved composition plugs before
mentioned. Metal bars attached to thin sheet metal preferably in strips are filled
between the spaces with leather or other material or bars pressed hollow & filled

page_text: in with composition or hemp or other suitable material may be used. Another
form consists in forming hollows in the sole in which hollows are placed rods or
thin bars which are sprung under a rim or sprigged or screwed to the edges of the
permanent sole. A sole is also formed by securing eylets to a thin metal plate or
the eylets may be punched up or formed out of the sheet metal the spaces between
the eylets being filled up with composition. An improved heel consists in a metal
rim round the edge of the heel combined with a movable central plate, metal or
other studs are passed under the rim & secured by the centre plate which may be
screwed down, the studs may also be further secured by a screw at the end of the
rum or the central plate may have a projection to prevent the studs sliding out.
Another form consists in fixing a spiral or other spring inside a cavity provided
in a sheet metal or other heel, the end of this spring being passed thro' a swivell
which is attached to a removable wearing part, which part is filled in with a hard
composition in its outer circle & a softer substance in its inner one which assists
the heel to keep level when revolved. Another form consists of attaching a plate
having a rim or screwed holes to a sliding cylinder or tube in which are provided
slots for the reception of screws or pins which may be attached to springs a rubber
washer is placed between the sliding & permanent part to give a slight spring.
Heels may also be made with a body part of rubber or other elastic material with
plates vulcanized thereto, to which permanent plates are attached removable
wearing parts..
The body part may be hollow & fitted with an internal spring. A further
improvement consists in cutting teeth around the head of the securing screws into
which teeth a spring clip fits preventing their jaring loose.
Detachable heel pieces are also made without bottoms & combined with tabs for
screwing to the heel, or with a turned over edge for attaching; these heel pieces
may also have perforations in the side, & in the bottom a narrow or part bottom
turned down may be used, these heel pieces are filled in with wearing material.
For attaching small bits of leather to the before mentioned sheet metal the bits
of leather are placed in a mould & the spiked plate fitting into the same mould is
forced down upon the leather.

HARRY FREDERICK HILL Brassfounder Sherwood Street Nottingham HENRY
HILL Brassfounder Sherwood Street Nottingham, 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 :-
This invention consists of making adjustable wearing parts for soles & heels of
boots & shoes & may be made in one piece to cover the whole surface or in small
pieces as deemed convenient. These wearing parts are chiefly composed of india-
rubber or composition or other suitable material with metal attachments or may be
made of metal only. One form of this invention consists of inctal eylets with a
thread inside the hole.
These cylets are fixed permanently into the sole. A. screw with a metal washer
is screwed into the eylet. In some cases the washer is dispensed with & the screw
head enlarged & the nick of the screw cut down into the shank of the screw to
facilitate their removal. The screw head may be covered with rubber or other
suitable material & may be made hollow & filled in with common flint or like
material & Portland or other cement that will set with water or other cheap hard
ement; or these screw heads & also the heel & other wearing pieces may be filled

page_text: canvas
in with rubber or other flexible material together with these hard parts, which.
may be of iron or other suitable material. Another form consists of making
coverings upon this principle to cover the whole sole & made of a foundation of
sheet metal punctured up into spikes or rough surfaces with or without a rim round
the edge & filled up with papier-mache wood-pulp or other suitable material
mixed with a glutinous substance or may be hemp & a glutinous substance
only, subjected to pressure these soles inay also be made with a
foundation & fixed upon moveable or permanent springs or strips of metal
or other suitable material, these flat strips being sprung or screwed under a
rim which is attached around the edge of the sole, this rim may also be
made detachable at one side if desired; strips of leather small pieces or whole
soles may have sheet metal attached by the punctured spikes or sprigged
from behind the sheet metal for attaching to the rims. These special soles
may also be attached by cylets & screws. Metal plates with projections for
allowing the screw heads to sink below the plane of the plates are combined with
screws & eylets. Plates or protectors are also attached to the sole by means of
projections or eylets which are passed through holes punched in the sole or are
secured by a rod or wire passing between the inner & outer soles & through the
holes in the eylets. The protectors may also be formed by bending wire into the
desired form & secured by the before mentioned rods which may be screwed or
plain. These wire wearing parts may also cover the whole sole & be attached by
rims or screws or by sprigs. These wires are bent so as to give an alternate bend
& open end, which make them very pliable. In cases where the screw heads are
covered the covering may be stretched over a projecting head into a groove & tied
on by thin cord or wire or simply stretched over. Rubber plugs may also be pressed.
into bevelled or grooved cylets let into the sole, & may have metal springs
inserted in the rubber to secure them thereto or projecting bars or catches which
fit into slots or holes made in the cylets may secure them. The eylets are split in
some cases to give accomodation to the screw. The soles may also be formed with
a piece of corrugated & perforated sheet metal with eylets on one side & filled
up with composition & also by a perforated plate which is fitted over studs of
metal, leather, or the improved composition plug before mentioned. Metal bars
attached to thin sheet metal preferably in strips, with spaces between the bars
which are filled with leather or other material. Or bars formed hollow & filled
in with composition, hemp, or other suitable material may be used. Another
form consists in forming hollows in the sole in which hollows are placed rods or
thin bars which are sprung under a rim, or sprigged, or screwed to the edges of
the permanent sole. A sole is also formed by securing cylets to a metal plate
or the eylets may be punched up or formed out of the sheet metal, the space
between the eylets being filled up with composition. An improved heel consists
in a metal rim round the edge of the heel combined with a moveable centre
plate metal or other studs are passed under the rim & secured by the centre
plate which may be screwed down; the studs may also be further secured by
a screw at the end of the rim or the central plate may have a projection to
prevent the studs sliding out. Another form consists in fixing a spiral or other
spring inside a cavity provided in a sheet metal or other hecl, the end of this
spring being passed through a swivel which is attached to a removeable wearing
part, which part is filled in with a hard composition in its outer circle & a softer
substance in its inner one, which assists the heel to keep level when revolved.
Another form consists of attaching a plate having a rim or screwed holes to
a sliding cylinder or tube in which are provided slots for the reception of screws
of pins which may be attached to springs; a rubber washer is placed between
the sliding & permanent part to give a slight spring. A further improvement
consists in cutting teeth around the head of the securing screw, into which teeth
a spring clip fits preventing their jarring loose. Detachable heel pieces are also
made without bottoms, & combined with tabs for securing to the heel or with a
turned over edge for attachment. These heel picces may also have perforations

page_text: in the side & in the bottom or a narrow or part bottom may be used; these
heel pieces are filled in with wearing material. For attaching small bits of
leather to the before mentioned sheet metal the bits of leather are placed in a
mould & the spiked plate fitting into the same mould is pressed down upon the
leather.
And in order that the said invention may be better understood we proceed
more fully to describe the same with the aid of the accompanying sheet of
explanatory drawings.
Fig. 1. is one form of metal eylet, & consists of a central ring or tube 1 which
is threaded upon the inside, & having four projections or spikes 2 upon the bottom
Hange 3, the whole may be cast in one piece.
Fig 1 is a section of Figure 1. shewing the eylet fixed into a piece of leather 5.
the projections shewn by the dotted lines are to prevent the cylet from turning
round.
Fig. 1. is a modification & consists of an eylet stamped out of sheet metal
in one piece, the wings or spikes 2 being cast out of the surface of the bottom
flange 3.
Fig. I is a section of Figure 11. shewing the spikes embedded into the
leather.
Fig. 3 is an eyelet secured by sprigs 3 the centre tube is also split down one
side as shewn at 4 and also in side view shewn at Fig. 3ª this nick is to allow of
the eyelet accomodating itself to the screw.
Fig. 4 is an cyclet for receiving a rubber, metal, or other suitable wearing
part and is in the form of an oval, & is provided with a small slot 5. 5 on
either side.
Fig. 4 is a section shewing the position of the slot 5 which is for the purpose
of holding the wearing part 6.
In Fig. 4" a metal catch or thin bar 7 is inserted into the wearing part, the
catch being long enough to project slightly on each side when at right angles to
the sides of the wearing part, a square hole 8 is made in the centre, a hole being
also made in the wearing part to allow a key to pass down to the catch 7 which is
turned until the ends of the bar or catch are turned to an angle when the wearing
part may be inserted into the eyelet and the catch may then be turned into the
slots 5. 5 by which it is held securely.
Fig. 4° shews the eyelet and wearing part secured together.
Fig. 5 is a modification in which the eyelet is made larger at the end next the
insole, a flexible wearing part 6 shewn in section at Fig. 5 is pressed into it, the
expansion of the stud preventing its easy removal; a metal spring 7 may be placed
in the stud or wearing part to give additional hold to the eyelet. This spring
is shewu at Fig. 5.
Fig. 5 is a mushroom headed stud having a flexible outer part 6 and an inner
tube of metal which may be hollow and filled in with any hard substance 8 or may
be solid metal.
Fig. 6 is a metal holding-piece made of sheet metal & screwed to the sole by
the central screw 3, the ends 2 are raised from the solc by a thin tool; and a
flexible wearing cap 5 shewn at Fig. 6ª is stretched over.
Fig. 6B is a section of the cap alone.
Fig. 7 is a screw stud or wearing part suitable for use with Fig. 1, 2 & 3 eylets.
The nick for securing is cut down into the screw shank to enable its removal when
the head is worn away.
Fig. 74 is a section of the same.
Fig. 8 is a modification in which a portion of metal is left around the ends of the
nick giving additional strength & may be in one piece or made in two parts as
shewn, & may be brazed together or the washer screwed on to the stud while hot.
Fig. 84 is a section of the same.
Fig. 9 is a plan of a wearing stud made in two pieces, holes 3. 3 are drilled down
the centre piece for tightening purposes, which may be displaced by a nick it

page_text: desired; the outer portion 1 is provided with a counter sunk flange 2 which holds
the centre piece & enables the whole of the stud to be worn down to the level of
the sole or heel without the outer part or ring falling off, small spikes 4, or a rough
surface are provided upon the underside to prevent rotation. In some cases I make
this stud of two kinds of metal, the screw being of non rustable material.
Fig. 10 is a section of a screw covered with Hexible wearing material.
The head
of the screw is provided with projections 3, 3, which pass thro' the sides of the
covering 1 by which the screw may be tightened. A nick is also shown at 5 in
the cover which allows of a screw driver being used if preferable.
Fig. 10 is a plan of the same. A projecting edge in the section is formed
underneath the head of the screw to hold the cap more securely.
Fig. 11 is a screw stud with a hollow frame top and the edges turning in to
better secure the material, 2 with which it is filled; spikes 5, 5, may also be
provided for the same purpose. A square hole (which may be of other suitable form)
is made thro' the screw & filling in material, or this hole dispensed with and the
lugs 3. 3. shewn also in plan 11 may be used for removal etc.
Fig. 12 is a wearing part stretched over a metal stud 2. The stud is not screwed
in this case but permanently fastened to the sole 4, by the turning over of the
edge 6. The sturl 2 may be of sheet metal or solid, or made of other tough
material. The cover 5 is further secured by a thin wire or cord shown by the
dotted line 7, which binds the covering into the recess.
Fig. 12 is a further modification in which the stud is made in two parts in sheet
metal & filled in with suitable material 3.
Fig 12 shews the two parts placed together ready for the inner edge 6 being
turned over.
Fig. 13, is a metal protector secured to the sole 4 by the eyelets 2. The cyclets
are brought up close to the countersunk projections which allow the screw heads
to sink below the level of the plate preventing their wear. I am aware that
screw heads have been sunk below the plate in this form, but not combined with
eyelets as shewn.
Fig. 14 is a section of a wearing part secured to the sole by projections 3. 3.
which are cast or otherwise connected to the plate 1. The sole is perforated with
holes thro' which the shanks 3, are passed, the underside of the sole being grooved
out as shewn at 5. 5., & rods of metal which may be screwed at one end or plain
& provided with a ring or head at the other as shewn at 6. 6 in the plan Fig. 14ª,
passing thro' holes 4, 4 fasten them to the sole.
Fig. 15 is a wire covering or protector bent out of one piece, the shanks 3, 3,
parsing through holes in the sole as in Fig. 14; the ends of the wire may be beut
down to form spikes 7, 7 for additional security. Fig. 15 is a plan seen from the
side next the insole.
Fig. 10 is another form of wire covering made to cover the whole surface of the
sule, & is secured by the screws & cyclets 6 which are shewn in section at Fig. 16^.
At the bends of the wire are brazed flat bits of metal, 2, which give a larger
holding surface for the screw heads. These bits may be made to stand out from
the end of the bend & form a ledge as shewn at 3 Fig. 16; this projection is
gripped by a rim of metal 4 sprigged round the sole. 5 is an eyelet receiving the
Screw 6, which screw is sunk below the bottom face of the wire wearing part. The
cross way bends shewn at 7. 7. 7 Fig. 16 are to give expansion when the wire is
bent to come up the edges of the sole, and sprigged as shewn at 8. Fig. 16 is a
section shewing the turned up ends and sprigs. These frames may also be filled
between the spaces with suitable wearing substance as shewn in section at Fig. 16".
Fig. 17 is a section shewing the application of the screws and studs to leather
sole. 1 is a leather sole in which holes are punched and the eyelets 2 driven in
3 is the first sole to which the eyeletted sole is sprigged or stitched. It will be
seen that the screws or studs are sunk down below the level of the sole in order to
leave a portion of the head for removing when worn down. 4 is a stud made with
a smaller head, 5, below the wearing part, specially for this purpose.

page_text: Fig. 18 is a section shewing the eyelets attached to a thin metal plate, 1,
preferably of sheet metal; the eyelets 2 are made without wings or spikes and are
brazed or otherwise fastened to the said plate 1. In some cases the sheet metal
may be stamped up to form a raised tube to form the eyelet as shewn at 3; this
plate may be perforated & is filled up with a composition of wood pulp hemp and
gunta percha, 4, or other suitable material. The screws may be of any suitable
shape, 5 being a spiked stud; spiked studs 5 suitable for cricketing or other purposes
may be used with the eyelets when desired.
Fig. 18 is a plan of the same with a portion of the composition or leather
removed shewing the metal plates and eyelets.
Fig. 19 is a modification of Fig. 18 with the plate 1 corrugated and perforated,
the eyelets 3, 3, are placed below the plate as shown, and the spaces filled in with
composition.
Fig. 19 is a plan of the same with a portion of the composition removed shewing
the plate and perforations.
Fig. 20 is a section of a detachable wearing part or sole made of sheet metal
having a turned up rim or edge 2; the flat surface of the metal is punctured and
raised up in spikes or roughened similar to a nutmeg grater or raised up in small
tubes similar to a honeycomb as at 3 these projections or roughened surfaces serve
to hold the composition securely, which is composed of hemp steeped in a glutinous
substance & compressed into the metal frame. Circular openings are left as shewn
at 4. 4. 4 for receiving screws 5, the plate being depressed at the bottom forming a
countersunk bearing for the screw head, preventing its being worn. Eyelets 6 are
fitted permanently into the bottom sole as shown. If desired a projecting edge may
be formed round the removable sole, and held by a rim as shown in Fig. 27. The
rubber plug 8, is for filling up the screw hole to prevent stones blocking it up.
Fig. 20 is a plan of the same.
Fig. 21 consists of a perforated plate 1 screwed down with eyelets 2; the plug 3
is made of an outer casing of metal 4 filled in with leather or composition. The
plug 5 is formed of leather sprigged to a metal plate 6. The plug 6 is of solid
metal; these loose plugs are secured by the top plate 1 passing over the small
surface & gripping the flange at the base of the plugs 3, 5 & 6.
Fig. 21 is a plan of the same.
Fig. 21 is a hollow flanged stamped metal plug filled in with small flints or flinty
material 2, combined with Portland or other similar hard cheap cement which plug
is combined with a composition sole 3 which is composed of wood pulp or papier
maché or similar material, hemp or other fibre & gutta percha or similar substance.
The plug may also be of solid metal and combined with this kind of sole, being
distinct from a leather plugged sole.
Fig. 22 is an arrangement of cross bars 1, attached to a strip or strips of pliable
sheet metal 2, which may cover the whole surface if desired. The bars are rivetted
or otherwise secured to the sheet metal as shewn in section 22ª. The space between
the bars may be filled up with leather 3, which being sprigged to the sole secures
the bars at the same time.
Fig. 23 is a combination of metal bars & india rubber the bars 1 having projections
or indentations as shewn at 2, which prevents the rubber or other material drawing
out. These bars are secured by eyelets as shewn in Fig. 234, the bars being wider
at the top than at the end nearest the eyelet, which serves to hold the rubber closely
to the sole.
Fig. 24 is composed of bars 1 which are hollow and filled in with cement and
broken flints or other suitable material; spikes 4 may be cast or formed within the
hollow for securing the filling material; these bars may be attached to strips or
sheets of metal as in Figure 22 and spaces filled with leather 3.
Fig. 25 is a method of attaching the wearing part or sole by means of cross bars
lying in groves formed in the sole. The sole is composed of a foundation of
canvas 2, upon which is cemented or otherwise attached the flexible wearing
parts 1; the bars 3 are turned over to come up the sides of the sole; these bars are

page_text: secured by eyelets 4 shewn in the plan 25ª, these eyelets being connected to a thin
strip of metal 5.
Fig. 26 is a method of securing the cross bars 1 by means of the metal clips 4.
which are shewn sprigged to the boot at Fig. 264. These bars are made sufficiently
pliable to be bent up as shewn in Fig. 26; when the bar or rod is released it
springs under the clips thus holding the wearing part secured in position.
Fig. 27 consists of a rim 1 which is sprigged or screwed to the boot 2. Sheet
metal pieces 3 covered with wearing material are sprung under the rim as in 26.
These discs are provided with spikes stamped up out of the metal similar to Fig. 20
for securing the wearing material, or it may be secured by sprigs 6 passed thro'
the back of the plate into the leather, small bits of leather being utilised for this
purpose as shewn in the plan 274. If desired however one piece of leather or other
inaterial may be used to cover the whole surface in which case one part of the rim
may be made detachable, a perspective view of which is given 27B, the portion
detached being shown by the dotted lines 4. 5 indicates pieces taken out of the.
edge of the rim to give more pliability.
Fig. 27 is a section shewing the wearing part divided at or near the centre and
held together by sheet metal 3, which is sprigged on to it. The metal edges 3 are
sprigged on each side for passing under the beforementioned rim, thus obviating the
necessity of covering the whole surface with sheet metal.
Fig. 27" is a detachable wearing part having a slot or nick at its base, through
this nick a sliding piece of spring steel metal 3 or other suitable material is passed
through, of sufficient length to project beyond this wearing part, for the purpose of
springing it under the metal rim before mentioned.
Fig. 28 is a modification of Fig. 27 & consists of a spring wire 3 over which is
sewn or cemented a canvas covering 4; upon this covering is cemented or other-
wise fastened the wearing part 5, the spring & flexible sole are compressed when
they may be placed under the rim 1, the expansion of the spring keeping it in its
place. The position of the spring around the outer edge of the sole is shown in
the plan Fig. 28. This spring may be dispensed with by the use of 2 flat strips of
metal indicated by the dotted line 6 and secured at the ends by the screws 7. 7.
Fig. 29 is a rim applied to a boot heel combined with a centre plate 2. The
rim is provided with projections 3 which are screwed to the boot heel and the
wearing studs 4 placed under the rim as shewn. The centre plate 2 screwed down
by the screws 5 holding them in position. The studs may be made hollow under-
neath as shewn at 6. The space below the centre plate may be left open to allow
of tightening down or the centre plate may be formed of two pieces of metal as
at 29 rivetted together, or projections may be used as provided as in 29°, the
centre plate may be dispensed with by using a double rim or groove as shewn
in 29" which is made in two parts and rivetted together.
Fig. 29 is a stud for this heel made in two parts, the bottom plate 1 being
riverted to the upper stud 2 this stud is formed hollow and filled in with wearing
material 3 which is held in the hollow by the spikes 4; in some cases the bottom
plate may be extended as shewn by the dotted lines 5 and secured by the screw 6.
Fig. 29 is a plan of Fig. 29 shewing the position of the screw 7 which prevents
the studs 4 drawing out at the ends; or the centre plate may be carried over the end
of the stud as shown by the dotted line 8.
Fig. 30 is a section shewing a metal plate 1 having small pieces of leather attached
by means of the spikes 2 or sprigs 3 & secured to the heel by the eyelets 4, which
are fixed into the last lift of the heel so that they may come close up to the metal
plate 1.
Fig. 30 is a plan of the same.
Fig. 31 is a section of a metal wearing part for screwing to a boot heel, being in
the form of a box or casing 1, having the bottom perforated with taper holes 2
perforations may also be made in the sides 3, these tapered perforations lighten the
weight & keep the material with which it is filled up firmly to the metal. Spikes
similar to the one shown at 5 may be provided to assist the same.

page_text: Fig. 32 is a wearing part provided with a projecting flange 1 for sliding under a
rim as shewn at Fig. 33; in this case the metal shell is not provided with a bottom
of any kind the filling in substance 4 being secured by the tapered sides.
Fig. 33 is a part section of an improved & simplified sliding detachable heel; a
metal plate with a turned over rim I is screwed firmly to the leather heel 2. The
detachable part 3 having leather fixed to it by means of the sprigs 4 or spikes 5
the metal plate being indented to allow the heads of the sprigs being sunk level
with the plate. When the wearing part is in position the screw 6 prevents its
removal, a spring 7 also prevents the screw from turning round by clutching the
notches provided in the screw head. If preferred holes may be drilled through the
screw head & into the plate as shewn, & a spring cotter or pin pressed into the hole
will answer the same purpose.
Fig. 33 is a part plan of the rim 1 with the wearing piece removed; it will be
seen that the rim is not turned over all round although it may be so, but this form
is preferable, not being so liable to stick. A plan of the removable part is shewn
in 33 showing the projections formed to correspond with the rim 1. Fig. 33°
is a longitudinal section shewing the position of the screw 6 and an eyelet 8.
Fig. 34 is a further improvement upon a metal heel, for which a Patent was
granted to one of the present inventors No. 409, 1877. This improvement consists
of filling up the hollow shell 1, with gutta percha or other suitable substance 2, &
fixing a spring 3, within the centre cavity the end of this spring is carried out and
passed through the swivel +, this swivel being fixed in the removable bottom piece.
The pin 6 projects slightly from the bottom of the shell, & holes are provided in
the bottom piece into which the pin fits. A. rubber or leather washer 7 is placed
between the two parts as shewn. This wearing part may be revolved by the hand
by raising the bottom part slightly out of contact with the pin 6 when it may be
turned round as desired. The wearing part is filled in with broken flint and cement
in the outer ring & and the inner circle with a softer composition or substance
making it wear more level. This heel may be made in the ordinary shape if
desired.
Fig. 34 is a plan of the wearing part.
Fig. 35 is a section of a heel, the central body-part (1) of which, is india rubber
or other elastic material which may be hollow & fitted with a spring or otherwise if
desired; a metal plate 2 provided with screwed bosses 3, and spikes is vulcanized
or otherwise secured to the india rubber. A similar plate 4 with perforations 5 is
fixed in the rubber by placing it in the mould when the rubber is formed to shape;
this heel is attached to the boot by the screws 6. 6. which are screwed from the
inside of the shoe. The detachable lift 7 is attached to the bottom plate by means
of the screws 8. This bottom plate may, however, be provided with a rim for
securing the wearing piece as in Fig. 33; the top plate 2 may also be dispensed
with and the rubber hardened for short distance down, or other hard substance
may be attached & ordinary joiner's screws used and screwed directly into the same
without the use of eyelets.
Fig. 36 is an outside & sectional view of a removable wearing piece 1, provided
with tabs 2, 2, which fit close to the side of the heel and are screwed to the metal
plate 3, which is screwed to the leather 4 by the screws 5. am aware that side
tabs have been used before but the special feature is the combination of the side
tabs with the perforated bottom 6, which is similar to Fig. 31. The side tabs may
also be combined with Fig. 32 in which there is no bottom whatever. A slight
modification is shewn in Fig. 364 in which the edge 2 is turned inwards and
downwards for a short distance, thus forming a hold for the filling material.
Fig. 36" is a plan of the wearing part 1, looking on the top or the face which
comes next to the metal plate; the perforations may take any suitable form desired,
two forms being given in the plan.
Fig. 37 is a plate with a rim or screwed holes 9 attached to a circular tube 2, in
which are slots 3 a screw 4 & spring pin 5 pass through the frame 7 into the slots,
securing the plate 1. The slots allow the plate to give way with pressure by

We wish to state that the studs and screws herein mentioned may be made of
other hard material than metal, such as ebonite or hardened rubber. In cases
where utility is considered before price, we use aluminium instead of the metal
hereinbefore mentioned, on account of its lightness.
Having now particularly described & ascertained the nature of the said inven-
tion & in what manner the same is to be performed we declare that what we
claim is-
1st. Eyelets formed substantially as set forth in Figs. 1, 2, & 3, and having the
