Year: 1889

page_text: 1 JAMES WILLIAM BLAKEY, Engineer, 90, Hyde Park 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 Invention consists of Improvements in Machinery or Apparatus wherewith to
pare and trim the Soles and Heels of Boots and Shoes." And in what manner the
Machine is constructed will be understood from the following description, reference
being made to the figures and letters on the accompanying two Sheets of
Drawings.
Fig. I Sheet 1 is a front elevation of my machine, shown as though it were paring
the sole of a Boot.
First I construct a framework A for carrying the various arrangements.
Through the centre of the table B I place a vertical shaft, the top of which stands
above the table, and is formed into a crosspicce D. At the other end of this vertical
shaft and underneath the table, I secure a bevel wheel I. I then place horizontally
in bearings under the table two shafts S and T, and on one of them I fasten the
bevel wheel L, also a pinion wheel J, and on the other shaft T, which is left suffi-
ciently long to pass through the side of the table, I attach a pinion wheel M, and also
the handle N.
On the crosspiece D of the vertical shaft, I place a stand A 1, in the bottom of
which is an oblong hole B 1, to fit over the reduced part of the crosspiece; See
Figs. 2 and 6 Sh. 2.
On the stand A1, I make a support E, which is grooved on its upper surface,
for the boot to rest upon. On the lower part of the stand, I make a vertical
bead "n," which forms a cam.
This vertical bead is placed between rollers, one of them, the roller "q" working
on the inner side, while the other rollers "p" "p" work on the outer side of the
vertical bead.
These three rollers are attached to the carriage P in such a manner as to allow them
to move freely on their centres,

page_text: I secure to the bottom of the carriage P a turned, boss "o,
," which passes through
a hole at one end of a slide piece Q, which moves longitudinally in a straight slot 0, 0,
in the table B.
This slide piece Q is retained in the slot O, O, by means of a collar, "r," on the
boss "o," and a plate, "s," fastened on the top of the slidepiece Q.

"
To the carriage P I fasten the box R, which has a projecting tail piece "h3.
In the vertical termination of this tail piece "h3," I fit a spring catch pin
In this box RI fit a bevelled slide piece U and into it I screw the vertical spindle ✗
and also the horizontal spindle V. I place on the spindle V a push spring","
the use of which is to force the bevelled slide piece U, the spindle ✗, together with
the tool, up to the boot.
To a boss "3," on the box RI attach one end of a lever W, and in, or about,
the centre of the lever W, I make a slot "3" Fig. 11 Sh. 2; and through it I
place a stud, which is screwed to the slidepiece U. My object in fastening the
lever Win this manner is to allow of the slidepiece U, with the spindle X, and the
tool being drawn back. I now press down the catch pin "y" into the hole "u" in
the spindle V, and thus hold them away from the boot.
I secure the boot to the support by pressure on the slipper G, obtained from
the screw K. I attach this slipper G to the last F by means of a pin "c3," which
which passes through holes in the lugs in the sides of the slipper G, and a hole in
a projecting piece on the lower part of the last F. I make the slipper G of a suitable
shape to suit any class of Boot. In the upper part of the last I drill a vertical hole,
to receive the lower part of the plunger, Y, which is reduced in diameter for this
purpose.

On the front side of the plunger H, I cut a vertical groove "e3" and into it the
screw 3" fits and this prevents the plunger from turning around.
the reduced part Y of the Plunger H, I cut a groove horizontally, and the last F is
attached to the reduced part Y of the plunger by means of two pins "d3" passing
through holes in the last F and into this horizontal groove; thus allowing the
last F, together with the slipper G to be turned on the centre of the plunger H.
I tap the inside of the plunger H to receive the screw K, so that I may raise, or
lower, the last F and the slipper G, by turning the hand wheel C, which is fastened
to the screw K by a pin "k 3."

Around
In the last, F, immediately under the centre of the plunger, I place a steel set
screw Z, which forms the bearing centre for the plunger. In the lower end of the
last F, I make a vertical hole
10, with a plate 63" fastened over it, and
through a hole in this plate, I pass one end of a vertical slide piece
this end of the vertical slide piece I place a spring "y," which I secure by a
screw "," and at the lower end of this slidepiece, which passes into a groove in
slipper G, I make a projecting piece "a 3" which draws the heel of the slipper up
to the plate "3" on last F, when the pressure is removed from the boot by
turning the hand-wheel C.

To work the machine I place myself on that

towards myself.
Since the roller " g "works on the inner side of the vertical bead "n" on the
stand A 1, and is attached to the carriage P, the slide piece Q, the carriage P, the
box R, the bevelled slide piece U, and the spindle X will be brought nearer to
the centre of the cross piece D by turning the handle N, and this movement will
also bring the supporting pieco E of the the stand A 1, into a corresponding position
with the slipper G to receive the boot.
I now place a boot on the slipper G, and by turning the handwheel I bring
down the plunger H, the last F, the slipper G, and thus fasten the boot on the
grooved support of the Stand A 1. The boot is now in position for paring.
'
Nearly at the top of the spindle X, I make a horizontal groove "r2"
Fig. 2, Sh. 2, and two sides "92" of the spindle X from the aforesaid groove
upwards I reduce to the diameter of the groove "r 2," thereby I leave two projecting

page_text: pieces "2," Fig. 3. I also make a vertical groove "82" and a horizontal
groove "2" in the spindle X for purposes that I shall afterwards state.
My heel tool, of which Fig. 2 is a side and Fig. 3 a front elevation, consists of
a framework "e2," in which I dovetail and secure a piece of steel "g2," which I
make into a blade of suitable shape to form the cutter. To the framework "c 2," I
connect one end of a union "f2" The other end of the union I attach by means
of a stud "d2," passing through a slot "p2" Fig. 2, in a supporting piece "b2,"
to a handle "
a," which is also placed in a slot "u 2" Fig. 3, at right angles to the

piece "62, and through the supporting piece, I drill a holo in which I place a
steel pin "2" which also passes through the slots k2 in the framework 2."
stud "d 2."
At the lower end of this supporting piece I drill a vertical circular hole "h2"
to fit on the spindle X. I also drill at the lower end and at the back of this
supporting piece "62" a small hole for a screw "u 2," the point of which projects
within the vertical circular hole "h 2."
"
On the side of the supporting piece "62" Fig. 2, I make a bevelled groove "12,
Fig. 3" for a correspondingly bevelled slide piece "12" Fig. 2. To the front of
this slide piece, I attach, by a stud "22" a guard m 2," of which Fig. 4, is a
front elevation, and Fig. 5 a plan. On the other end of the bevelled slide
piece "12" I make a small nick "y 2" to receive a vertical spring "n2" which is
attached to the supporting piece "2" by
"a 2."
a screw
This spring when in
the nick "y 2" of the bevelled slide piece "12" holds the guard in its
position.
I now place that end of the bevelled slide piece "12," which has the nick in it,
between the edge of the blade and the inner side of the framework "c 2," into
the bevelled groove "12" Fig. 3, made in the supporting piece to receive it. I
then put the spring into the nick.
*
It will be seen that one end "13" Fig. 5 of the guard m 2" lies on the
blade "g 2," and that one part "m3" of the guard is cut away to prevent the
guard from damaging the cutter.
I make these guards of different sizes, so that the leading point "n3" will be
nearer or further away from the blade according to the size of the heel to be
pared.
To pare a heel with a metal plate on it, the part "o 3" of the guard is made to
stand just above the cutting edge of the blade; while in the case of a heel without
a heel plate I make the part "03" to stand under the cutting edge of the blade, thus
allowing the tool to pare the whole depth of the heel.
1 fasten in front of the blade to the tool frame "c2" Fig. 3 a guard "v2,"
which can be adjusted by means of a screw

the guard.

I then turn the handle "a" of the tool sideways, which movement carries the
supporting piece "62," the tool frame " c 2," with the tool, around on the spindle X,
and brings the point of the screw u2," into the horizontal groove "2," which
prevents the supporting piece "62," from moving upwards or downwards on the
spindle X.
tr
The guard "m 2," being attached to the bevelled slide piece "72," which is placed
in the bevelled groove in the supporting piece, is also prevented from moving

line with the bottom of the heel.
I now draw back the lever W, which releases the catch pin "v," from the
hole " ke "in the spindle V. The spring "t" on the spindle V then distends itself
and presses forward the slide piece U, with the spindle X, and the tool up to
the corner of the heel. At the same time by means of the handle "

I now give a description of my sole tool, which consists of a framework"
Fig. 8, in which I dovetail and secure a piece of steel g" made into a blade of
suitable shape, to form a cutter.
In one side of the framework "c," I make a slot "e," for purposes that I shall
afterwards state.
I place within the sides of the framework "c" one end of a centre piece "b," with
a vertical hole "h" in it. In the other end of the centre pieco, I make a
slot "3," in which I attach the handle " a (which is the same in construction as
the handle for the heel tool) by means of a stud "d" Fig. 8.
ود
I attach the framework "c," to the centre piece "b," by means of two studs "j"
in such a manner as to allow the fromework "c" to move freely on the centres of
these studs. In the centre piece, I make a tapped hole, and through the slot "e,"
on one side of the framework "c," I place a wing screw f" into this tapped hole.
By this means, I can set and secure, the framework "c," and the tool to any suitable
bevel.
,,
с
و"
On the other side of the framework" c," I attach a guard "93" Fig. 10; by
means of a wing screw " 3 passing through a slot in the guard. This guard "3"
is a piece made at right angles and one side "3" is secured to the framework "
as beforementioned, whilst the other "s3," comes in front of the frame-
work "," and can be set, by means of the wing screw "z" in the slot of the
guard, to suit the cut required. On the top side that comes in front of the
framework "s3," I attach a small roller guard, “k” by means of a stud. This roller
guard "" has to work in the seat of the boot sole and thereby, I prevent, the
blade"
"from cutting the upper of the boot.
"
I now place the sole tool on the spindle X, and let it go up to the sole, and guide it
around in the same manner as I do the heel tool.
I now take the pressure off the slipper G; by turning the handwheel (), and take
the boot from the machine.
<
In some cases I make the sole tool in a somewhat different manner, which I will
now describe, see Fig. 9. Instead of securing it in its proper position for cutting by
the wing screw "f" as shown on Fig 10, I dispense with this wing screw, and
attach a lever to the centre piece, by means of a stud "3" which forms a working
centre for the lever; and by this lever I can give any desired bevel to the cutter "
whilst paring the boot.
"y
In place of the top-piece E, I may make a hole in the bottom of the cam "n"
in which to fit the shank of a last, or I make the toppiece into a last, and thus
the boot may be pared with the sole upwards. In this case the framework "c2"
of the Heeltool, is placed on the supporting piece "62," with the opposite end to
the one as shown, nearest to the top of the spindle X, and the gearing is arranged
to move the boot towards myself, instead of away from me as it does as shown
in the drawings, and by my previous description. I also reverse the sole tool,
on the centre piece, when the boot has to be pared with the sole upwards.
In place of the lever W, that is secured to the slide piece U, I may attach a foot
lever, that may be used to press the tool to the boot, in place of the spring "i" on
the horizontal spindle V, or to draw back the slide piece U as desired.
