We, HARRY WILLIAM SURSHAM, of 61B Knox Road, Wellingboro; in the County,
of Northampton, Foreman, and WILLIAM HENRY STEVENS, of 89 Princess Road,
Leicester, Boot and Shoe Manufacturer, do hereby declare the nature of this
invention to be as follows :-
The improved lasting apparatus is constructed and operated in the following
manner.
The frame rests upon a stand and is provided with a downwardly projecting pin
fitting into a socket to enable the jack to be turned about as may be required by
the workman; this frame is formed with a fixed standard at the heel and with an
adjustable standard at the toe to enable the last to be placed between two pairs of
hinged moulds carried by such standards and acting to grip the toe and heel. The
last is supported upon two screw standards capable of adjustment in height on the
frame to suit the last for the time being in use, and such screw standards are

preferably fitted with wheels by which they can be rotated.
standard is fitted with a carrier, on which are hinged or pivotted the hinged heel
moulds, and the adjustable toe standard is formed with a lever arm the lower end
of which is acted upon by a screwed rod, the end of which bears against the frame,
or is fixed therein, so as to enable the upper end of the said lever arm to be moved
to or fro and fixed in position to adjust the angle of the toe moulds to suit the
last used. Through the upper end of this lever arm passes a screw on the outer
end of which is fixed a hand wheel by which it can be rotated whilst the inner end of
such screw carries a block which is suitably guided and carries the hinged moulds
for acting upon the toe.
The hinged toe and heel moulds are formed with projecting flanges at their upper
sides which act to wipe the leather over the last. By regulating the angle of the
lever arm carrying the toe moulds, the jack can be arranged for different sizes and
patterns of lasts, and by rotating the hand wheel the toe moulds can be made to
approach to or recede from the heel moulds to hold or release the last.
On each of the hinged toc moulds is pin jointed a gripping jaw, which is shaped
to fit the curve of the flange of the 'toe inould, and acts in combination therewith as
a pair of nippers, between which the edge of the upper is placed; these moveable
gripping jaws are provided with rising handles so shaped and placed as to be readily
grasped by one hand whilst the other hand acts upon the wheel to rotate the screw
which moves the toc moulds forward. The head of each of such moveable gripping
jaws is fitted with an adjustable screw stud to press the last with the inner sole
attached thereto downwards and they are each formed so as to fit on the top as well
as on the edge of the flanges of the toe moulds, whereby a secure hold of the upper
leather is obtained.
The operation is as follows:-The last with the upper leather thereon is placed
on its supports and between the toe and heel moulds, the toe leather is gripped by
the nippers above described and the last and inner sole pressed downwards; the
wheel for moving the toe moulds forward is then rotated thereby causing the leather
to be drawn over the toe of the last by the action of the toe mould flanges and the
nippers. When the toe moulds are pressed fully home, the moveable.gripping jaws

COMPLETE SPECIFICATION.
Improvements in Apparatus for Lasting Boots and Shoes.
We, HARRY WILLIAM SURSHAM of 61 Knox Road, Wellingboro, in the County
of Northampton, Foreman, and WILLIAM HENRY STEVENS of 89 Princess Road,
Leicester, Boot and Shoe Manufacturer, do hereby declare the nature of our said
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
The improved lasting apparatus or jack is constructed and operated in the
following manner.
The frame rests upon a stand and is provided with a downwardly projecting pin
fitting into a socket to enable the jack to be turned about as may be required by
the workman; this frame is formed with a fixed standard at the heel and with an
adjustable standard at the toe to enable the last to be placed between two pairs of
hinged moulds carried by such standards and acting to grip the toe and heel. The
last is supported upon two screw standards capable of adjustment in height on the
frame to suit the last for the time being in use and such screw standards may be
fitted with wheels by which they can be rotated. The fixed heel standard is fitted
with a carrier on which are hinged or pivotted the hinged heel moulds and the
adjustable toe standard consists of a lever arm the lower end of which is acted upon
by a screwed rod the end of which bears against the frame or is fixed therein so as
to enable the upper end of the said lever arm to be moved to and fro and fixed in
position to adjust the angle of the toe moulds to suit the last used.
Through the upper end of this lever arm passes a screw on the outer end of which
is fixed a hand wheel by which it can be rotated whilst the inner end of such screw
carries a block which is suitably guided and carries the hinged moulds for acting
upon the toc.
The hinged toe and heel moulds are formed with projecting flanges at their upper
sides which act to wipe the leather over the last.
By regulating the angle of the lever arm carrying the toe moulds the jack can
be arranged for different sizes and patterns of lasts and by rotating the hand wheel
the toe moulds can be made to approach to or recede from the heel moulds to hold
or release the last.
On each of the hinged toe moulds is pin jointed a gripping jaw which is shaped
to fit the curve of the flange of the toe mould and acts in combination therewith as
a pair of nippers between which the edge of the upper is placed; these moveable
gripping jaws are provided with rising handles so shaped and placed as to be readily
grasped by one hand whilst the other hand acts upon the wheel to rotate the screw
which moves the toe moulds forward. The head of each of such moveable gripping
jaws is fitted with an adjustable screw stud to press the last with the inner sole
attached thereto downwards and they are each formed so as to fit on the top as
well as on the edge of the flanges of the toe moulds whereby a secure hold of the
upper leather is obtained.
And in order that our said invention may be more clearly understood and readily
carried into effect, we will proceed aided by the accompanying drawings more fully
to describe the same.

a is the frame which is provided with a downwardly projecting pin a', fitting into
a socket to enable the machine or jack to be turned about as may be required by
the workman; this frame a is formed with a fixed standard at the heel and with
an adjustable standard a³ at the toe to enable the last to be placed between two
pairs c. d. d of hinged moulds carried by such standards a³, a³ respectively
and acting to grip the toe and heel. The last e is supported upon two screw
standards f. g. capable of adjustment in height by being screwed more or less into
the frame a and of being fixed in such position by lock nuts, the standard fis
fitted with an elastic bearing surface f2 to prevent marking or injury to the upper
leather and if desired such standards f. g. may be fitted with wheels to facilitate
their rotation.
The fixed heel standard a³ is fitted with a carrier a on which are hinged or
pivotted the hinged heel moulds ee and the adjustable toe standard a³ consists of a
lever arm which is pin jointed at a³ to the frame a and is acted upon at its lower
end by a screwed rod a fixed in the frame a. and provided with lock nuts a to
firmly secure the standard a³ in any required position.
Through the upper end of this lever arm or standard a passes a screw on the
outer end of which is fixed a hand wheel ¹ by which it can be rotated, whilst the
inner end of such screw acts upon a block, to which the toe moulds d are pin
jointed and which is provided with guide rods passing through guide holes formed
in the projecting ends of a tapped block or nut carried in the upper end of the
standard or lever arm a³.
The toe and heel moulds d and c are formed respectively with projecting
flanges at their upper sides which act to wipe the leather over the last e.
By regulating the angle of the toe standard or lever arm a³ carrying the toe
moulds d the jack can be arranged for different sizes and patterns of lasts and by
rotating the hand wheel the toe moulds d can be made to approach to or recedo
from the heel moulds to hold or release the last e.
On each of the toe moulds dis pin jointed at da gripping jaw which is shaped to
fit the curve of the flange d' of the toe mould d and acts in combination therewith
as a pair of nippers between which the edge of the upper leather is placed, these
moveable gripping jaws are provided with rising handles j' so shaped and placed
as to be readily grasped by one hand whilst the other hand acts upon the wheel h
to rotate the screw which moves the toe moulds d forward. The head of each of
such gripping jaws is fitted with an adjustable screw stud to press the last
with the inner sole attached thereto downwards and they are each formed so as to
fit on the top as well as on the edge of the flanges d' of the toe moulds d whereby a
secure hold of the upper leather is obtained.
f
The operation is as follows: The last with the inner sole attached thereto and
with the upper leather thereon is placed on its supports and between the toc
and heel moulds d. e the toe leather is gripped between the gripping jaws and the
flanges of the toe moulds d and the last and inner sole are pressed downwards
by the studs, the wheel is then rotated thereby moving the toe moulds d
forward and causing the upper leather to be drawn over the toe of the last by the

page_text: action of the toe moulds d flanges d¹ and gripping jaws j. When the toe moulds d
are pressed fully home the moveable gripping jaws are thrown back so as to liberate
the edge of the leather for the usual tacking operation.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. In a lasting machine or jack the peculiar combination, arrangement and mode
of operation of the parts substantially as herein shown and described.
2. In a lasting machine or jack the combination of a swivelling frame having a
fixed standard at the heel, an adjustable standard or lever arm at the toe, adjust-
able last supporting standards between the toe and heel standards, a pair of flanged
moulds hinged to the heel standard, a pair of adjustable flanged moulds hinged to
a carrier guided in a block at the upper end of the adjustable toe standard, a screw
passing through such block to give forward motion to the flanged toe moulds and
hinged gripping jaws carried by the toe moulds, fitted to the flanges thereof and
provided with rising handles by which the said gripping jaws can be simultaneously
held by one hand whilst the other gives motion to the screw acting upon the toe
moulds substantially as herein shown and described.
3. In a lasting machine or jack the combination with a suitable frame, of hinged
toe and heel moulds, having forwardly projecting flanges on their upper sides,
means for holding, guiding and advancing the toe moulds and hinged gripping jaws
carried by the toe moulds substantially as herein shown and described.
