I, HENRY ALFRED OLDERSHAW of 38 High Cross Street, Leicester in the County of
Leicester, Machine Maker do hereby declare the nature of my 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 object of this invention is to provide an apparatus whereby the heels of boots
and shoes may be pared or trimmed to the proper shape at one operation.
In the accompanying drawings Fig. 1 represents a front elevation of a machine
for paring boot heels constructed according to my invention. Fig. 2 side elevation
of same partly in section. Fig. 3 side elevation of paring knife and attachment
drawn to an enlarged scale. Fig. 4 end elevation and Fig. 5 plan of same. Fig. 6
enlarged view of under side of the machine showing driving gear. Figs. 7 and 8
are cams hereafter referred to. The same letters denote the same parts in all
the figures. a is base of machine, table, c holder for rest or holster while
putting on or taking off boot, d is the bolster upon which the boot heel to be
operated on is placed and secured by means of the plate or caine which is raised
or lowered by means of the screw f and hand wheel g the holster is provided
with a spring plate and spikes jj passing through slots in the said spring plate
for the purpose of holding the boot firmly while the heel is pared, the bolster d
slides in a groove in the plate which plate has a compound sliding and rotating
motion imparted to it by means of the spur wheel and D shaped spur wheel m
which are kopt in gear by means of the slot and T headed bolt, the wheel /
is rotated by means of a handle attached to the spindle n which spindle has keyed
to it the bevel pinion o gearing into the bevel wheel p keyed to the spindle
which is also keyed the wheel l. The pillar which is attached to the sliding
plate has the cam s attached to it and the pillar t carries at its upper extremity
or is formed into a slotted piece u in which slides the upper extremity of the
arn the pillar t also carries the arm to which is pivotted the swivel to jointed
to which is the arm and adjusting link y to allow of various sizes being pared
The knife A is secured to the
on one machine carrying the swivel knife holder z.
to

page_text: holder hy means of clips B B₁ and screws C C D is a guide hereafter referred
to. E is handle for holding knife while paring, F is a spiral spring, G is a roller
His a guide which runs between the welt and the upper.
The action of the apparatus is as follows the machine being in the position shown
at Fig. 1-the boot to be operated upon placed heel upwards upon the holster d
the said bolster being vertically under the heel, the plate or cam e is screwed tight
down upon the bottom of the heel by means of the hand wheel g the guide H is
placed between the welt and the upper, the roller G bears against the cam S and
the guide D rests on the plate or cam e, the operator now grasps the handle E
with one hand and presses the knife A against the heel and turns the operating
handle attached to the spindle with the other hand, the cams compel the knife
to assume such positions that the heel is shaped and pared ready for blacking
at one operation without any subsequent rubbing down or smoothing. The motion
of the operating handle is now reversed and the machine brought to the original
position the bolster run back the boot taken off and another one put on and the
operation repeated.
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: :-
1st. In an apparatus for paring the heels of boots and shoes the swivel knife
holder substantially as described.
