Improvements in Machines for Paring the Heels and “Fore-parts
of Boots and Shoes, Applicable also to Burnishing such Parts.
"
I, JOSEPH ROSE, of Richmond Place, Gibson Street, in the City and County of
Newcastle upon Tyne, Wholesale Slipper Manufacturer, do hereby declare the nature
of said invention, and in what manner the same is to be performed, to be particlarly
described and ascertained in and by the following statement
My invention consists in certain improvements upon existing paring and burnishing
machines, constituting an improved machine by which the operations of paring and
burnishing, or either of them, may be more quickly and efficiently performed.
The improvements comprise an adjustable table or rest, against which the boot or
shoe is held by the workman and by which the width of the cut is determined; a
guard or "fence" which being adjusted, determines the depth of the cut and enables
the cutting tool to pare round the back and along the sides of the heel, along the
varying curves of the sole and round the toe; an auxiliary cutter to remove the
"bit" on upper edge; a guard or "fence" to protect the upper leather from injury
and a
"fan-blast" (used only when "paring" is being done) to draw away the
"debris" from the cutting tool and keep it cool.
In paring machines, now in use by the trade, a separate machine (or part of a
machine) is required for the heel and "fore-part" respectively and in many of them,
whether the boot or shoe is fixed or held in the workmans hands, there is great
complication of parts, and the depth of paring by the cutter is difficult to regulate,
the least accidental or negligent slip causing too deep a cut whilst the upper leather is
often abraded and injured by the cutters.
The machine which I have invented and which I will now describe, with reference
to the accompanying drawings, effects the paring of the heels and "fore-parts" with a
uniform depth of cut without risk of a slip causing too deep a cut, it will pare in a
straight line, a half circle, or a series of varying curves such as in the edges of the
sole from the heel to the toe, round the toe and the back of the heel, and the width of
the exposed edges of the knives can be adjusted, to suit the width of the part to
be pared, all by simple mechanism readily operated by one hand of the workman.

An auxiliary cutter at the same time running in the crease, takes out the
or rough edge left by the paring. I also provide for gathering all the "debris"
resulting from the work into a proper receptacle by the suction of a small fan,
causing at the same time a current of cold air to traverse the edges of the cutter
knives and keep them cool.
When burnishing is to be done the cutting tool is replaced by another which
may be heated, before being put on the spindle or may be kept heated to a proper
temperature by gas or other means when fixed on the spindle.
Fig. 1 on the accompanying sheet of drawings shows an elevation of a double
ended machine one half in section.
"
Fig. 2 shews an end elevation of same. Figs. 3, 4 and 5 show enlarged details
of the adjustable table or rest, the adjustable guard or
« fence and the guard for
protecting the upper leather.
Fig. 6 shews a face view, full size, of the adjustable guard or
fence," with
the guard for upper leathers attached to it, and Fig. 7a side elevation of same.
Figs. 8, 9 and 10 shew three views of the tool holder (full size) with the paring
knives, the auxiliary cutter and the mode of fixing upon the spindle of the machine.
The same letters refer to corresponding parts on all the Figures.
A is the standard which is a hollow casting; B is a counter shaft carrying fast
and loose sheaves C, C¹ for the belt from engine which is shifted by the weighted
lever D operated by the workman's foot. E is a belt from the counter shaft to the
machine spindle F carried in long bearings G, GI at each end. H is the
adjustable table or rest actuated by the hand wheel J working a pinion K in the
rack and fixed by a set-screw M. The lower part of the table or rest H forms
a semicircle and tapers (see Figs. 3 and 4) to allow the workman a little liberty
in handling the boot and it has an opening through it at N (see dotted line
Fig. 4) through which the debris from the cutter is drawn by the suction of the
Fan O on end of counter shaft B (Fig. 1) into the hollow standard and discharged
at P. Qis the adjustable guard or
: fence moved vertically against the face of the
table or rest H by the fixed screw R worked by a hand wheel in the nut S on back
of the guard or "fence" (see detail on Figs. 3. 4 and 5 also Figs. 6 and 7). T is
the guard for the upper leather moving vertically with the "fence" Qbut adjustable
independently upon it by the screws U (see Figs. 6 and 7). The lower portion of
the fence Qforms a fork which embraces the cutter and, being adjusted, fixes
the depth of the cut of the knives and also causes them to pare the boot in a
straight line or varying curves, as for the sides of sole and the toe, or a semi-
circle, as for the back of the heel.

The tool holder V (see Figs. 8, 9 and 10) is fixed upon the outer end of the
machine spindle F by double nuts and a washer against the collar, beyond the tapered
part of the spindle. The tool holder V receives the knives W, which are shaped to
suit the work to be done, in slots provided in it in which slots the knives can be
adjusted as they wear.. The cutter X, for dressing off the "bit" or rough edge,
runs in the " crease of the hoot as indicated by dotted out line and is fixed
with the tool holder V upon the spindle by the double nuts and washer. When
light "pumps," or similar work, are to be pared the cutter X will be removed not
being required.
On Fig. 1a boot is shewn by dotted lines being pared round the toe, the sole
resting against the table H, against which it is firmly held by the workman who,
at the same time, presses it upward against the "fence" Q which has been ad-
justed to allow the cutter knives to take off the requisite paring the workman moving
the toe in the fork of the "fence" till it is finished. The back of the heel is
similarly pared and the adjustment of the "fence" Q, relatively to the cutting edges
of the knives, will enable the workman to follow the varying curves of the sole without
risk of unequal paring. The width of the paring to suit varying thicknesses of heels
and foreparts is fixed by moving the table or rest H upon the rack L so as to leave
the required width of the knives exposed, the "fence "Q and the guard T moving
with it.

page_text: The machine as shewn by the drawings has the spindle horizontal, which form I
prefer as both ends are conveniently available, either both for paring or one for
paring and the. other for burnishing, or one end may be used for the heels only the
other for the "fore-parts." The improvements are however equally applicable to
machines with the spindle vertical.
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
f
1st. In a machine for paring the heels and "foreparts" of boots and shoes with
revolving cutters, a guard or fence" against which the work is held and which,
being adjusted, enables the heel, the varying curves of the sides and toe to be pared,
to a fixed and uniform depth of cut constructed and operating substantially as
described and shewn.
2nd. In combination with a guard or "fence" for the purposes above described an
adjustable guard to prevent injury to upper leather during the process of paring,
constructed and operating substantially as described and shewn.
"
3rd. In combination with a revolving cutter for paring the heels and "fore-parts
of boots or shoes an auxiliary cutter to remove the bit or rough edge left by the
paring cutter constructed and operating substantially as described and shewn.
4th. In a machine for paring the heels and "fore-parts" of boots or shoes with
revolving cutters, a fan to draw away the "debris" from the cutters and cause a
current of cold air to keep them cool.
5th. In combination with a guard or fence, and the guard for upper leathers herein-
above described, a revolving tool for burnishing the heels and "fore-parts" of boots
and shoes heated by gas or otherwise, substantially as described.
6th. A machine for paring the heels and "foreparts" of boots or shoes comprising
the standard or pillar, the counter shaft carrying an exhaust fan; the spindle carrying
the revolving cutters with the auxiliary cutter; an adjustable table or rest of improved
form, to guide the work and regulate the width of paring; an adjustable guard or
"fence" to regulate the depth of cut and adapt it to the shape of the heel
and "fore-part;" and an adjustable guard to protect the upper leather from injury,
the whole combined and operating substantially as described and shewn or, in the
alternative form, fitted with a revolving burnishing tool in place of a paring tool, the
exhaust fan being thrown out of action; constructed and operating substantially as
described and shewn by the drawings.
