I ROBERT HEAP SOUTHALL, of 18 Chapel Lane, Headingley, Leeds in the County of
York, Machine Maker, do hereby the nature of my invention for IMPROVEMENTS IN
MACHINERY FOR PARING OR TRIMMING THE SOLES OF BOOTS AND SHOES to be as
follows:-
My object is to hold a boot or shoc firmly in an expanding last bolted to a frame in
such a manner that the centre of the circle of the toe may be over and correspond with
the centre of a table placed a proper distance beneath round which I carry certain
arrangements consisting of a rest, vertical levers and tool, which latter I draw against
the edge to be pared by means of springs and cause a shaving to be cut off by carrying
the tool longitudinally along one side, round the toe, and, along the opposite side to the
distance required. To accomplish this I construct a suitable frame to which I bolt an
expanding last. To this frame I also bolt a longitudinal table with a semi-circular end
and slot down the middle, a suitable distance beneath the expanding last with the centre
of the circular end exactly or thereabouts beneath the centre of the toe part of the
expanding last I place a slide in the slot in the table and screw a stud in such a position
to it that when the slide is at the extreme end the said stud will come exactly under
the centre of the toe as well as in the centre of the round end of the table I cause the stud
to carry an iron rest with joints at each end. To one end I joint a vertical arm or
lever which carries the cutting tool and to the other end I joint a vertical lever with pawl.
I connect the two vertical levers together with springs and by this means draw the tool
towards the centre and consequently against the edge to be pared. I make one end of
the rest to span the edge of the table, and on the under side secure a small roller. This
roller I move with a slotted cam which I key on to a shaft and drive with a pair of
bevel wheels and an ordinary winch handle. When using the machine the tool is
drawn against the edge to be pared by the vertical lever expanding the springs and
held there by the pawl being drawn into a notch. By turning the handle the tool is
carried along one side of the boot sole round the toe and along the opposite side to the
distance required.

Improvements in Machinery for Paring or Trimming the Soles
of Boots and Shoes.
I, ROBERT HEAP SOUTHALI. of 18 Chapel Lane Headingley Leeds, in the County of
York, Machine Maker, 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 :—-
My object is to hold a boot or shoe firmly on an expanding last bolted to a frame in
such a manner that the centre of the circle of the toe may be over and correspond with
the centre of a table placed a proper distance beneath round which I carry certain
arrangements consisting of a rest, vertical levers and a tool, which latter I draw against
the edge to be pared by means of springs and cause a shaving to be cut off by carrying
the tool longitudinally along one side, round the toc, and along the opposite side to the
distance required. My invention is illustrated in the accompanying sheet of drawings
in which Fig. 1. represents a side elevation of my machine.
Fig. 2 plan of slotted table, with rest, slide, and steadying levers.
Fig. 3 slotted cam and roller for driving rest.
Figs. 4 front view 5 side elevation, and 6 plan of tool with holder and socket in
which it works.
Figs. 7 and 8 side view and plan of expanding lever used in tool for regulating the
angle of cutter and thickness of edges.
A Fig. 1 is the frame for carrying the various arrangements. B is the bracket with
slot, and can be raised or lowered as required through the bolt C. D is a piece hinged
to the bracket B and can be raised and kept elevated by the locking piece E to
allow an operator greater case in putting on or taking off another boot.
F is the
expanding last secured firmly to the piece D which can be expanded by the screw G.
His the boot and I the tool for paring the edge shown fully in Figs. 4, 5 and 6. K.is
the tool holder, and I the socket in which it works. M. is the vertical lever hinged at
both ends, on the top for carrying the tool socket which work in centres M² which
enable it to rise or fall according to the shape of the boot sole and at the bottom to the
horizontal lever N to enable the tool to move in or out according to the shape or
form of sole. The lever N is made to up and down also, to enable the tool to follow the
various inequalities, by the roller O coming in contact with the inclines P P P Fig. 2
fixed (but adjustable) to the plate Q the lever N is hinged to the slide rest It Fig. 2 to which
is hinged also the vertical lever S carrying the pawl Tand springs U one on each side.
This arrangement is used for drawing the tool to its work and keeping it there, till the
operation is complete. The slide rest R works in the centre V in the slide W Fig. 2
and consists of upper and lower parts, one above and one below the table. The
stud working in the centre V binds both together. The steadying levers X X are
hinged to the arms Y Y of the part underneath by the studs Y Y and are pressed
against the plate Q by the springs ZZ. Underneath also in a suitable place is secured

page_text: the roller a working on a stud which works, in the slot in the cam which drives
the whole through the bevel wheels ele and winch handle d. The lever e¹ rod f¹
and treadle I use for drawing the tool to its work when the machine is started
the slide rest R being then in a sideways position when the angle piece al comes
under the rod lever e¹ which on being pulled downwards by the treadle g¹ draws
the springs U till the pawl T falls into the notch and thereby brings the tool
against the edge to be pared and holds it there till the operation is complete. The
tool works on the stud Figs. 4, 5 and 6 fixed to the cranked holder K so that it may
adjust itself to any angle required through the leading point ¹ Fig. 8 on the lever ¹. This
lever works on the stud and is pressed upwards by the spring m¹. The flange n'
runs against the boot sole and thereby expands or contracts the space between according
to the thickness of the edge being pared while the guard o¹ runs on the upper or welt
side. The chief feature of this lever is to retain the exact form of the boot sole
which it could not do if it were made to take an even shaving the whole breadth of
thick soles inasinuch as the middle soles of most boots are generally much larger than
the true outsole it will be seen in Fig. 7 that it is so shaped that a thin shaving may
be cut from the sole only and the middle soles and welt shaped to it. p¹ is the knife
or cutter for paring the edge, and the cutter for cleaning the welt side. This latter
is cranked so that it may pass through the upper plate in which a thoroughfare is cut
in such a manner that a guard Fig. 6 may be formed to protect the upper. In
working the machine I slip a boot on the expanding last F and tighten with the
screw & I then turn the handled backwards till the tool reaches the place where I
wish to commence paring I then draw the tool against the edge by pressing down
the treadle g which acts through the rod f¹ and lever e¹ coming against the angle piece a¹
till the pawl T enters the notch made for it I then release the treadle and turn the
handle forward when the tool is made to traverse the edge of sole along one side round
the toe and along the other side as far as it is required thereby cutting off two shavings
one off the edge and the other off the welt.
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.-
The general arrangement and construction of the machine.
2 The fixed expanding last and table with corresponding centres.
3 The slide rest for carrying the various levers, springs, and tool.
4 The cam for driving.
5 The arrangement and construction of the tool particularly the lever with
spring m and tag knife q¹.
