Improvements in Apparatus for Paring and Trimming the Soles and
Heels of Boots and Shoes, also for Burnishing or Finishing the
same.
I JAMES WILLIAM BLAKEY Engineer No. 1 Brudenell Square Hyde Park Leeds
Yorkshire-do hereby declare the nature of this invention to be as follows:-
-
My invention refers to improvements in machinery or apparatus wherewith to Pare,
Trini, and Burnish the Soles and Heels of Boots and Shoes. A patent was granted to
me No. 1478-89, for Paring and Trimming the Edges of Soles and Heels'; but
(referring to the drawings furnished with Specification No. 1478) in this invention I
make a hole through the boss O that is attached to the carriage P, and between the
bevelled slides in the box R place a roller, and behind the roller a crosspiece to
which I screw a spindle on which I place a push spring. To the opposite end of the
slide piece U that carries the spindle X on which I place the tools, I fasten one end of
a chain which passes over the before named roller and through the hole in the boss O
to the under side of the table, to this end of the chain I attach a hook and foot lever,
and by this foot lever the tool can be drawn up to the boot. The push spring on the
spindle will push back the slide piece U when the foot is released from the lever.
The weight of the lever is raised by a spring.
On one side of the slide piece U that carries the tools, I fix an upright or vertical
piece, and to the supporting piece or sides of the heel tool I fix an adjustable slide
piece one end of which presses against a cam that is hinged to a centre or fitted in a
slide or groove in the before named upright. To the sides of the stand A' 1 fasten
ar other cam to operate with the before named cam on the upright piece which will
keep the tool at a cutting angle.
With this arrangement I do not require the guards to be so long as in the before
named specification.
I also place a screw in the guard that lays on the blade, and with the screw I can
adjust the guard to pare the whole depth of the heel or protect the blade when paring
a heel with a metal plate on it.
On the support E which is grooved for the boot to rest on in the before named
specification I fit pieces of rubber or leather so that the boots are not damaged while
being operated on.
I also secure pieces of rubber or leather to the bottom of the slipper G.
The continuous cam or vertical bead I also make of somewhat different shape
instead of being straight at the sides, I make it more of the shape of the grooved
top piece or support E.
On the top of the sole tool I fix a guard and small knife to take the bit off the top
edge of the sole, and also one at the lower side to take the bit off the bottom of the
sole, these knives to be so arranged as to take any thickness of sole.
In place of the continuous cam may use springs or levers to push the tools up to
the boot, or a rack of similar shape to the cani as shown with teeth on the inside or
teeth on the outside. Immediately above this toothed rack I may make a jack or make
an arrangement so that the boot can be fixed thereon.
In place of the paring tools I may arrange burnishing tools, to which I apply heat
and give suitable inovements.
Dated this 13th day of August 1889.

JAMES WILLIAM BLAKEY Engineer Vinduct Kirkstall Road Leeds Yorkshire 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 improvements consist of a rearrangement and additions to the several and
respective parts for which a Patent No. 1478 Jan. 28-89 was granted to me for
Paring and Trimming the Soles and Heels of Boots and Shoes, and these improve-
ments will be fully understood on reference being made to the figures and letters on
the accompanying sheet of drawings, and also to the specification and drawings
supplied with the above patent.
Fig. 1 is a side elevation of the reconstructed parts for the paring of heels.
Fig. 2 is a view of clamp and cam n for the paring of soles.
Fig. 3 is a side view of cam na with supporting piece E cut away for the reception
of cam v intermediate piece o and the cam a.
Fig. 4 is a plan of cam intermediate piece w and cam a.
Fig. 5 is a front view of sole knife made to pare the edge and also top and bottom
edges of sole at the same time.
Fig. 6 is a side view of sole knife.
Fig. 7 is a side view of clamp for holding the top end of the heel paring blade.
Fig. 8 is a side elevation of heel tool to be used with the cams as arranged
on Fig. 3.
The same letters denote the same parts in all the figures.
A is base of machine, & table, c vertical shaft to which are attached the supporting
piece d (for cams and v) the arm a boss e screw plunger g and spring-plate Cand
also under the table the bevel wheel h.
The plunger g is provided with a spring plate and with spikes passing though
slots in the said spring plate for the purpose of holding the boot firmly on the cam
while the heel is being pared.
B is a hand wheel for raising and lowering the plunger g by the screw f.
I
D is a rod fastened at one end to the plunger the other end passes through a hole
in the small boss E and thus keeps the plunger g in position.
i is a sliding bed plate, to one end is fastened the stud; and to the other end is
fastened one end of the chain k, the other end of the chain passes over a roller and
underneath the table and is attached to the rod 1, the other end of the rod is hooked
and is attached to the treadle or lever m.
Immediately above the sliding piece is another bed plate K with the vertical
upright o attached thereto and to it is secured the horizontal spindle p.
The bed plate K with the vertical upright o has the stud n which passes through
the raised part in the bed plate i fastened to it, but in such a manner that it may move
freely on its centre.
At the opposite end of the bed plate K to that where the vertical upright o with
spindle p is I place a movable slide piece 7 that may be moved backwards or forwards
by means of the screw s.
On the other end of the slide piece I place a roller r its use I will explain
hereafter.
H is the tool block and to it is fastened the blade u by means of the clamp y at the
top end and clamp at the lower end.
=
I make a hole in the tool block H to fit on the spindle p, the handle or levert is
also fast to the tool block.
The clamp z is screwed at one end, and this end I place through a hole in the
lower end of the tool block, and on this the screwed end I place a nut.

page_text: In the front part of the clamp = I make a slot, and through it I place one end of
the blade.
Fig. 7 is a side view of clamp y and it is also screwed at one end and it has also a
nut thereon. This screwed end is placed through the vertical slot I in the top end of
the tool block as shown, and the other end of the blade is placed through the slot in
the clamp y
On screwing up the nut of clamp 1 draw back the blade to the tool
block and thus secure the lower end, and on screwing up the nut of the clamp y I
draw the blade up to the tool block at the top end, thus it is made fast.
=
The clamp y when placed in the slot I can be raised or lowered to suit the length
of the blade and the top of the blade can be secured in any desired position. The slot
in the front part of the clamp z enables the blade to be put with the curve in any
desired position, the intermediate piece to being made less than the cams, so as to
prevent the front of the clamp or end of blade catching thereon, and yet enabling
the operator to move the tool on the centre p wherewith to give any desired pitch to
the heel.
The can is always made larger than the cam x and must be made suitable to the
shape of top piece about to be pared. The came is always made the same shape as
top piece of heel about to be pared on its upper surface but the lower edge is bevelled
off as shown Fig. 3. Assuming the top pieco of a heel about to be pared be of the
shape of the cam z from the line across shown on Fig. 4 the cam with intermediate
piece w and cam are of suitable shape for the purpose or as near to it as they can be
figured. In the bottom of the cam I make two holes as see fig. 4, and in the
supporting piece d see Fig. 1 I screw two pins and the came with intermediate
piece w and cam a are placed thereon.
P
The stud n in the bed plate K with the vertical upright o in which I make fast
the horizontal spindle for the tool H, is placed about midway between the cutting
edge of the blade and the centre of the roller r which are about 14 inches apart, yet.
it is not bound to this position The tool is simply placed on the spindle p and the
vertical upright o attached to the bed plate K keeps the tool to its work as soon as the
pull or cut comes on to the blade, and the blade is kept at a cutting angle by
means of the roller r operating on the cam and the back of blade on the cam ..
There being nothing in front of the tool H I am enabled to slide it off the
spindle p and place thereon another tool with suitable blade attached thereto, and
the change from a straight to a curved heel is effected in a second or two.
The action of the apparatus for the paring of heels is as follows, the boot to be
operated on is placed with the heel downwards on the cam the plunger g is
sent down by the screw on turning the hand wheel B and the boot held fast on
the cam x.
The operator now places one foot on the lever m thus forcing the
bed plates and K together with the roller and tool up to the cams and the
handle L is grasped by one hand and the handle t of the tool with the other, and
on turning the operating handle L the cams and a keep the tool at a cutting
angle and the operator can pare as closely to the upper as desired. The operator
releases the treadle and handle of the tool H, and the foot laver is raised by the
spring as shown (or it may be weighted to accomplish this) the bed plates and tool
are drawn back by the spring M the operating handle is reversed and boot and
machine brought back to its original position.
Fig. is a view of clamp with plunger of different shape for holding boots while
the soles are being pared. The plunger is sent down by the handwheel and screw,
and kept in position by a rod D as shown in Fig. 1. The part d is made fast to the
vertical spindle with crosspiece D shown in Fig. 1 sheet 1 of my previous patent, but
the cam n n is only shown a part of the way round, the cam n n works in the rollers
on the carriage P (in the drawing accompanying the previous specification) and the
sole tool as there described may be used for paring the sole, but where it is desired to
ake the bit off the top edge of the sole I make the blade as shown at Fig. 5 and 6 N,
he top edge is rounded so as not to cut the upper and the bend is made to suit any
lesired bevel. Where it is desirable to take off both edges of the sole I make the
econd projection o in the blade at a suitable distance from the top blade to suit the

page_text: width of the sole about to be pared. I may make these sole blades with either one or
both of such bit-knives as desired.
Fig. 3 is the cam n n with support E cut away to receive the cam a intermediate
piece w and cam v, and will be. understood on reference to Fig. 1 sheet 1 and Fig. 6
sheet 2 of my patent No. 1478 Jan. 28-89.
The tool I use in connection with these cams is shown at Fig. 8 (this specification)
which I will now describe.
The tool block is similar to the one herein described and the blade is clamped
thereto in the same manner but the tool is fastened to the centre block O on the
spindle p by means of a collar and pin as shown. The roller r is also fastened to this
block both of course work freely on their centres. Through the centre block O is
a vertical hole T that fits on the spindle X (described in the previous specification).
The distance of the roller and blade edge are the same in relation to the spindle X as
are described in this specification respecting Fig. 1 and the centre or stud n.
a
I also make an alteration in the carriage P (described in the previous specification)
I make a hole through the boss that is attached to the carriage P and place.
roller between the bevelled slides in the box R, I attach one end of a chain to the
slide piece and pass the other over the roller immediately above the hole in the
boss and down and through the hole it is then attached to a rod such as is shown
in Fig. 1 of this specification that is hooked to the treadle m, and the slide piece with
spindle and tool may be thus forced up to the boot, and by a pull spring attached to
a stud on the back of slide piece U (described in the previous specification) and the
other end being fastened to a stud in place of the catch pin the slide piece and tool
may be drawn back and the treadle raised by means of a spring or weight.
When it is intended to work the machines by power I make the vertical spindle c
longer than is shown on the drawing, and in place of the bevel wheel or horizontal
gearing I fasten to the vertical spindle, two friction plates and between these plates I
place a loose pulley with a boss attached, and in this boss I make a groove and in this
groove I place two studs that are attached to a forked lever. This lever is fixed to a
stud for a fulcrum while at one end a handle is formed so that the operator by raising
or lowering the loose pulley (which said pulley is being driven by power) brings
it in contact with either of the friction plates and thus the spindle may be moved
either way.
In place of sharpening the blades, I round them on their face side and apply heat
thereto, and use them thus for burnishing.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The arrangement and adaptation of the cams & and with intermediate piece w
with the supporting piece E cut away for their reception as herein described and
shown at Fig. 3.
7"
2. The arrangement construction and adaptation of the intermediate piece 10
between the cams and thereby enabling the guide roller and horizontal spindle p
to be placed in such positions that the tool can be quickly changed as herein described.
3. The sole knife with the bit knife N made from one piece of steel for bevelling
the top edge of sole and also for paring the edge of sole as herein described.
4. The sole knife with the bit knives N and O made from one piece of steel for
paring the edge and also the top and bottom edges of sole at the same time as herein
described and shown at Figs. 5 and 6.
5. The arrangement construction and adaptation of the several and respective parts
together forming the heel tool to be used with the cams as shown on Fig. 3, and
placed on the vertical spindle X of my patent No. 1478 Jan. 28-1889 and herein
described and shown on Fig. 8.
