MACHINERY FOR THE MANUFACTURE OF METAL HEELS FOR BOOTS AND SHOES
"
This invention relates to improvements in machinery for the manufacture of
metal heels for boots and shoes from blanks of sheet metal which are bent and
pressed into the shape of a metal heel the joints being afterwards united by brazing
in the ordinary manner.
For this purpose according to our improvements a blank of sheet metal is cut
or stamped out from sheet metal and of such a form that when it is bent and
pressed up as hereinafter described it will assume the exact form of the heel of a
boot or shoe and when finished can be readily fixed thereto
The operating parts of the machinery employed for carrying out our improve-
ments consist of a revolving table which carries the dies upon which the metal
blank is bent and pressed into the desired form.
The metal blank is placed and fixed by clamping upon one of the series of dies
mounted on the periphery of the revolving table which in its revolution carries
the blank under suitably curved surfaces mounted on the machine which bend the
blank to form the outer side or surface of the heel and at the same operation folds
over part of the blank to form the bottom plate or tread and also the inside wall
or breast of the heel. The heel is then removed from the die and brazed and
finished in the usual manner.

page_text: Suitable mechanism is arranged to actuate the revolving table and operating
parts of the machine springs being employed to govern the action of the pressing
surfaces upon the blank as it is brought into contact with them
In order to form a round or revolving heel in accordance with our improvements
the blank is cut so as to form the outer cylindrical surface of the heel the joint
and circular heel plate being fixed by brazing
Or we make round or revolving heels by cutting them from tubular metal and
stamping or pressing into the shape desired in suitable dies the bottom plate being
fixed thereto by brazing.
An ordinary shaped metal heel may also be made in accordance with our
improvements from tubular metal stamped and pressed into shape in suitable dies
According to another part of our improvements we manufacture metal heels
from suitably shaped blanks of sheet metal by pressing or stamping them in
suitably shaped dies. The blanks are split in such manner as to readily bend up
into the desired shape in the dies without subjecting the metal to any undue
strain. The split parts are brazed up and the heel finished in the ordinary
manner

This Invention relates to improvements in machinery for the manufacture of

pressed into the shape of a metal heel the joints being afterwards united by brazing
in the ordinary manner.
For this purpose according to our improvements a blank of sheet metal is cut
or stamped out from sheet metal and of such a form that when it is bent and
pressed up as hereinafter described it will assume the exact form of the heel of a
boot or shoe and when finished can be readily fixed thereto.
The operating parts of the machinery employed for carrying out our improve-
ments consist of a revolving table which carries the dies upon which the metal
blank is bent and pressed into the desired form.
The metal blank is placed and fixed by clamping upon one of the series of dies

blank under suitably curved surfaces mounted on the machine which bend the
blank to form the outer side or surface of the heel and at the same operation folds
over part of the blank to form the bottom plate or tread and also the inside wall
or breast of the heel. The heel is then removed from the die and brazed and
finished in the usual manner.

In order to form a round or revolving beel in accordance with our improve-
ments the blank is cut so as to form the outer cylindrical surface of the heel the
joint and circular heel plate being fixed by brazing.
Or we make round or revolving heels by cutting them from tubular metal and
stamping or pressing into the shape desired in suitable dies the bottom plate being
fixed thereto by brazing.
An ordinary shaped metal heel may also be made in accordance with our
improvements from tubular metal stamped and pressed into shape in suitable dies.
According to another part of our improvements we manufacture metal heels
from suitably shaped blanks of sheet metal by pressing or stamping them in
suitably shaped dies.-The blanks are split in such manner as to readily bend up
into the desired shape in the dies without subjecting the metal to any undue
strain. The split parts are brazed up and the heel finished in the ordinary
manner.
And in order that our invention may be clearly understood and readily carried
into practice we will proceed to describe the same with reference to the Drawings
DESCRIPTION OF THE DRAWINGS
Figure 1 is a side elevation, Figure 2 a front elevation and Figure 3 a plan of
machinery suitably arranged and constructed in accordance with our improvements
for the purpose of folding and shaping metal blanks suitable for being used as
metal heels for boots and shoes.
A is the revolving table carrying the dies upon which the sheet metal blanks A¹
(shown separately by Figure 4) are folded and B the block for folding the blanks
round the dies. The block B has a spring surface wound around it in order to
impart a slight degree of elasticity to the surface of the block and thus prevent
any undue strain.
The metal blanks A¹ may be cut or formed without the piece marked a² to form
the bottom of the heel which piece a³ can be formed separately and be inserted
and brazed to the bent up part A¹ when completing and finishing the metal heel.
The mechanical parts are all put in motion by means of a strap passing over the
pulleys C. The shaft C' upon which the said pulley and strap runs is geared to
the main shaft E by a pinion and spur wheel ƒ. f.
The action of the machine is as follows:-A suitably stamped out sheet metal
blank A' is placed upon the die a the lever D is then depressed by means of the
cam E the nose b of the said lever coming in contact with the clutch F presses it
firmly upon the top of the metal blank A¹ the bell crank lever e is forced by a
spring over the top of the clutch and holds it in the position as forced by the
lever D. The ratchet lever G then comes into action by means of the stud c. on
the disc H which said disc is caused to revolve by the bevil wheels I I actuated
by the spur wheel J and pinion K direct from the intermediate shaft C¹.
The ratchet lever is caused to make a longer stroke than the actual stroke of
the disc H by the multiplying wheels M M acting upon the racks N N. The
revolving table A is then pulled round one third of its circumference and the
sheet metal blank A¹ is in position for the first part of the process.
The block B is then forced down by the lever O which is actuated by a stud on
the disc P working in a slot in the lever the said block B forces the sheet metal
blank round one side of the die a and at the same time folds down the piece to
form the bottom of the heel. The ratchet lever again comes into action and forces
the revolving table A round another stroke at the same time carrying the blank A¹
round the lower surface of the die a when the block B is forced up and finishes
the operation of folding.

page_text: This operation is repeated blanks being continually fed in and as the table A
revolves the clutch F is released and the folded sheets are removed.
The movement of the table A is arrested after each stroke by means of a stop L
which is actuated by the lever Q governed in its action by the cam R. The edges
of the folded blank where they come together are brazed up to complete the
metal heel.
Having thus described the nature of our invention and the manner of performing
or carrying the same into practice we would remark that we make no claim to
any of the mechanical parts separately which are well known and in common use
But what we claim is :-
First. The improved arrangement of machinery for the manufacture of metal
heels boots and shoes in which a metal blank is folded formed and shaped into a
metal heel substantially in the manner hereinbefore described and represented
in the drawings hereto annexed.
Second We claim the improved method of manufacturing hollow revolving
metal heels by first cutting suitable lengths from tubular metal and then stamping
or pressing them in suitably shaped dies to form the hollow heels a bottom plate
being fixed thereto by brazing substantially as and for the purpose hereinbefore
described.
We also claim the improved method of manufacturing ordinary shaped metal
heels for boots and shoes from short lengths of tubular metal stamped and pressed
into shape in suitable dies substantially as described.
Third We claim the improved method of manufacturing metal heels for boots
and shoes from suitably shaped metal blanks by pressing or stamping them into
the desired shape in suitably shaped dies the split parts being brazed up and the
metal heel finished substantially in the manner herein before described.
In witness whereof I the said Edward Kynaston Bridger have hereunto set
my hand and seal this twenty ninth day of February in the year of our
Lord One thousand eight hundred and eighty four. ("
