Improvements in Machinery for Attaching the Soles to Boots
and Shoes.
I WILLIAM HENRY DORMAN, of the Hawthorns, Newport Road, Stafford,
in the County of Stafford, Engineer, do hereby declare the nature of this
invention to be as follows:-
My invention relates to machinery used for attaching the soles to boots & shoes
and applies to that part known as the ". jack
or apparatus which carries the boot
while being operated upon by the machine.
My said invention is intended particularly to apply to machines for nailing the
soles to boots & shoes where it is necessary for the operator to be able to move
the boot into a great variety of positions while still maintaining command over
the boot during the time the machine is operating upon it.
My improved jack "is mounted so as to be capable of turning horizontally
upon a vertical post having a rising and falling movement, by treadle or otherwise,
and the jack may be kept up to the machine head either by a spring or
counterweight.
The jack is provided with a plate pivotted so that it rocks in the direction of
the length of the boot when the latter is in position on the "jack."
Sliding lengthwise in the plate is a rack the rear end of which, that is the end
towards the boot heel, is furnished with a pivot.
On this pivot swings in a more or less horizontal direction a second plate which
extends forward in the direction of the boot toe and lies
upon the first plate.
The second plate carries a frame supporting the "last upon which is the boot.
This frame stands generally vertical, its length being in the direction of the length
of the boot, but is pivotted so that it may be rocked sidewise that is, in a direction
across the width of the boot.
The "last" is secured upon this frame in such a way as to be easily detached
and the frame is provided with a part for supporting the toe of the boot.
The sliding rack previously mentioned gears into a pinion mounted in the plate
and this pinion gears with another rack in such a manner that when the boot is
moved to and fro in the direction of its length the two racks move in opposite
directions.
To the rack which moves in the direction opposite to the movement of the boot
I attach a weight to balance the weight of the boot and the last in their various
positions.
Springs may be provided to maintain the last frame in an upright position and
suitable stops limit the movements of the several parts where required.
If desired may pivot the "last" frame upon a saddle which slides to & fro
across the sliding rack on a slide provided for the purpose. In this case
with the pivot in the rear end of the rack and also with the swing plate.
Dated this 2nd day of June 1890.

Improvements in Machinery. for Attaching the Soles to Boots
and Shoes.
I, WILLIAM HENRY DORMAS, of the Hawthorns, Newport Road, Stafford,
in the County of Stafford, Engineer, do hereby declare the nature of this inven-
tion, 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 machinery used for attaching the soles to boots, and
shoes and applies to that part known as the "jack" or apparatus which carries the
boot while being operated upon by the machine.
My said invention is intended particularly to apply to those machines for nailing
the soles to boots and shoes where it is necessary for the operator to be able to
move the boot into a great variety of positions while still maintaining command
over the boot during the time the machine is operating upon it.
My improved jack" is mounted so as to be capable of turning horizontally
upon a vertical post having a rising and falling movement by treadle or otherwise,
and the "jack may be kept up to the machine head either by a spring or counter
weight.
:
The jack is provided with a plate pivotted so that it rocks, in the direction of
the length of the boot when the latter is in position on the "jack."
Sliding lengthwise in the plate is a rack the rear end of which, that is the 'end
towards the boot heel, is furnished with a pivot.
On this pivot swings in a more or less horizontal direction according to the
position of the "jack a second plate which extends forward in the direction of
the boot toe and lies upon the first plate.
The second plate carries a frame supporting the "last" upon which is the boot,
This frame stands generally vertical, its length being in the direction of the length
of the boot but is pivotted so that it may be rocked sidewise, that is in a direction
across the width of the boot..
The last is secured upon this frame in such a way as to be casily detached and
the frame is provided with a part for supporting the toe of the boot.
The sliding rack previously mentioned gears into a pinion mounted in the plate
and this pinion gears with another rack in such a manner that when the boot is
moved, to and fro in the direction of its length the two racks move in opposite
directions:
To the rack which moves in the direction opposite to the movement of the boot,
attach a weight to balance the weight of the boot and "last" in their various
positions
Suitable stops are provided for limiting the movements of the several parts where
required.
If desired 1.may pivot the last frame upon a saddle which slides.to & fro across
the sliding rack on.a slide, provided for the purpose. In this case I dispense with
the pivot in the rear end of the rack and also with the swing plate.
My invention is illustrated. by the accompanying drawings in which,
Fig. 1 is an elevation of my improved "jack."
Fig. 2 is a plan of the same.
Fig. 3 is an elevation in section.
Fig. 4 is a part.plan.

The socket "" fits upon the upper end of the post "a" and is capable of
turning thereon. Its upper end is tapped to receive the screw "" of the fork "m"
and a jam nut "n" is provided to secure the screw "1" at any desired height. The
upper end of the fork "m" has a pivot "o" upon which rocks the plate "p" of

pivot " upon
which swings (more or less horizontally according to the position
of the "jack") a plate "." The plate lies upon the plate pand. carries

handle has a tee headed bolt" at the lower end which slides in a way"
prepared for it in the frame "w so that by turning the handle "/"the cushion "d"
may be cramped in any desired position to suit varying lengths of boot.
A stop is provided to prevent the racks & from sliding out of

In the modification shewn in Figs. 7 & 8 the rack "g" carries a cross slide "m"
upon which slides a saddle "n" "The frame" 20 is pivotted upon this saddle the
plate "" and the pivot ""being dispensed with. The cross slide "m¹ " may be
flat or curved upwards at the ends in the form of a portion of a circle.
<
The jack is used in the following manner. The operator places his foot upon the
treadle and brings down the jack "e" away from the head of the machine
and places the last ""with the boot upon it upon the piece "the toe being
allowed to rest upon the cushion "." By means of the cramping screw
a¹" a
tipping movement is given to the lever " about its pivot "y" so as to press
down the toe upon the cushion and thus the last is firmly secured upon the
jack.
"
The operator then raises his foot upon the treadle "j" and allows the jacke
to rise (under the action of the counter weights "h") guiding the boot with his
hands into the proper position under the machine to commence work.
"
The machine is then set in motion and as the boot is fed along by the action of
the machine the operator so manipulates the "jack" "c" as to always present the
boot in the correct position to receive each rivet, the construction of the "jack
allowing complete freedom of movement and the balanceweight "" taking off as
much as possible of the weight of the last. After the operation is complete the
machine is stopped and the last removed.
The counterweights ""at the rear of the machine are somewhat in excess of the
combined weight of the jack, last and boot and keep the boot sole always up to the
head of the machine without effort from the operator and the balance
weight on the "jack"""moving as it does in a direction opposite to that in
which the operator moves the last preserves always a more or less perfect balance
of the jack "c" upon the pivot "o."

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. In a machine for attaching the soles to boots and shoes a "jack," or apparatus
for carrying a boot, having a moving balance weight governed by the moving of
the boot by the operator, in such a manner that in every position into which the
boot may be moved, during the operation of attaching the sole thereto, the balance
weight shall automatically assume such a position as to maintain the general
balance of the boot and the several parts of the "jack," substantially as
described.
