Improvements in Work Supports for Boots and Shoes.
I, WILLIAM HENRY DORMAN, of the Green Hall, Stafford, Engineer, do hereby
declare the nature of this invention to be as follows:-
-
The object of this invention is to provide a work support or "jack" to be used
on machines for screwing, nailing, pegging or similar operations around the heel
seats of boots and shoes, while the same are upon the last.
The work support is so constructed, that although the hole in the last may be
situated out of centre with the heel, or formed out of square to the heel seat, yet
adjustments may be made in the work support so as to bring the seat true with
the centre upon which the last revolves during the screwing or similar operation.
The pin which carries the last, and on which it is prevented from turning, is
provided with a curved slide which is at right angles to the length of the last, and
the curve is struck from about the centre of the heel seat. The slide is adjustable
in a block, which again is adjustable upon a second curved slide struck from about
the same centre as the first slide, and lying at right angles to it, or in the direction
of the length of the last. By means of these two slides the last can be tipped in
any direction.
In the stem which carries the above slides is formed a third slide, which is
horizontal and in the line of the last. Its object is to enable the last to be set
lengthwise in relation to the lowermost point of support of the "jack," which is
preferably in the form of a cup and ball, but with a peg to prevent rotation on a
vertical axis.
Between the ball and the horizontal slide is an angling arrangement by which
the upper part of the stem may be set at any desired angle with the lower part, and
a socket bearing is provided above the angling arrangement, on which the upper
stem and last may be revolved.
The cup bearing for the ball is preferably provided with a horizontal slide in
which it can be adjusted.
Improvements in Work Supports for Boots and Shoes.
I, WILLIAM HENRY DORMAN, of the Green Hall, Stafford, Engineer, 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 obiect of this invention is to provide a work support or "jack" to be used

page_text: on machines for screwing, nailing, pegging or similar operations around the heel
seats of boots and shoes, while the same are upon the last.
The work support is so constructed that although the hole in the last may be
situated out of centre with the heel or formed out of square to the heel seat yet
adjustments may be made in the work support so as to bring the seat true with
the centre upon which the last revolves during the screwing or similar operation.
In presenting the work to the machine it is necessary that the outer portion
of the heel scat surface may be moved about by the operator beneath the nozzle
or guard of the machine at a uniform height in reference thereto so that the
screws, pegs or nails shall all be driven level or to a uniform depth with reference
to the heel seat surface.
It is also necessary that the boot incline-as it is revolved by the operator―so
that the screws &c. may all be driven inwards, or towards the centre about which
the boot is turned, and that this inclination be capable of adjustment in
amount.
My invention is illustrated by the accompanying drawings as applied to the
machine known as the standard screwing machine:-
Fig. 1 being a front view and
Fig. 2 a side view, a portion of the same being shewn in, section.
The pin a which carries the last 6 and on which the last is prevented from
turning by the feather c is provided with a curved slide d which is at right angles
to the length of the last 6 and the curve is struck from the point e which is
approximately the middle point between the back of the heel seat and the two
corners of the breast. The slide d is adjustable in a block f which again is adjust-
able upon a second curved slide y struck from the same centre e as the first slide d
and lying at right angles to it, or in the direction of the length of the last b. By
means of these two slides d and y the last b can be tipped in any direction.
Two set screws d¹ and g¹ serve to secure the slides & and g respectively when
the last is properly set.
In the stem h, h, which carries the above slides & and and at right angles to
it is formed a third slide i which is in the line of the last b. Its object is to
enable the last 6 to be set lengthwise in relation to the lowermost point of
support of the "jack" which is in the form of a cup and ball k but with a peg l
to prevent rotation on a vertical axis.
The stem h h is carried upon a socket bearing on which it and the last b are
revolved by the operator.
The
Between the ball and the slide i upon the stem h is an angling arrangement m
by which the stem h may be set at any required angle with the stem n.
piece m¹ is supported on the pivot m² carried by the piece m³ and stem n and a
Set screw m in a slot m5 secures the piece m¹ to the piece m³ when adjusted.
The object of this arrangement is to enable the operator to vary the amount
of inclination at which the nails or screws shall be driven.
The cup bearing for the ball k is provided with a horizontal slide p in which it
can be adjusted and it is secured by the screw q.
The hand nut r and screws serve to adjust the height of the last 6 for different
thicknesses of work.
The invention is shewn in the drawings as applied to the machine known as
the Standard Screwing Machine, t being the ordinary guard and u the nozzle of the
machine, but the invention is equally applicable to other boot and shoe machinery
for performing somewhat similar operations.
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:
In combination with screwing, nailing, pegging or similar machines used in the
manufacture of boots and shoes
1. The use of the herein described work support by which the heel seat may be

page_text: adjusted relatively to the nozzle or the guard of the machine so that the outer
portion of the surface of the heel seat, when moved about by the operator. as
required in the nailing or screwing operation, shall be presented at a uniform
height with reference to the said nozzle or guard.
2. Carrying the last supporting pin in two curved slides at right angles to each
other and having their curves struck approximately from the middle of the
surface of the heel seat for the purpose of enabling the last to be tipped into any
desired position, as described.
3. The use of the pin a, slides d and g, stem h, slide i, and socket o for the
purpose of adjusting and manipulating the boot, as described.
4. The work support or "jack" provided with the pin a, feather c, slides & and
stem h, slide i, socket o, angling arrangement m, nut r, cup j, ball k, and
slide all as described and illustrated and for the purpose specified.
