I WILLIAM JACKSON, of 11 Caroline Street, Eaton Square, in the County of
Middlesex, Engineer, do hereby declare the nature of my Invention for "IMPROVE..
MENTS IN THE CONSTRUCTION OF MACHINES FOR CHANNELLING THE SOLES OF
BOOTS AND SHOES, AND ANALOGOUS PURPOSES," to be as follows:-
The object of my invention is to effect improvements in machines for channelling
the soles of boots and shoes, such improvements being also applicable to other
analogous operations.
In carrying out my invention I fit the knife, which cuts the channel in the sole,
into a knife holder, which holds the same firmly and acts as a guide thereto. This
holder is fitted in suitable bearings in which it is capable of a limited amount of
motion. This motion is governed by a spiral or other spring, which has a tendency
to drive the knife forward or backward as arranged, and also by a screw and nut,
whereby the distance of the knife from the edge of the sole may be regulated at
pleasure, or may be entirely withdrawn therefrom..
A lever is provided for lifting the knife out of the channel when necessary.
By the use of my invention simplicity, cheapness, and efficiency are ensured, and
the distance of the knife from the edge of the sole is regulated with precision by:
the adjustable guide; the spring being capable of adjustment to the required
strength, and the operation being performed without the aid of foot power.

I WILLIAM JACKSON, late of 11 Caroline Street, Eaton Square, in the County
of Middlesex, but now of 2 Harvey's Yard Battersea Park Road in the County of
Surrey Engineer, 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 my invention is to effect improvements in machines for channelling
the soles of boots and shoes, such improvements being also applicable to other
analogous operations.
In carrying out my invention I fit the knife, which cuts the channel in the sole,
to a suitable knife holder, which holds the same firmly. The holder is fitted to
suitable bearings, whereby it is rendered capable of a limited amount of motion.
This motion is governed by a spiral or other spring, which has a tendency to drive
the knife downward, and the sole is also guided by a thrust block having a spring
and screw nut, whereby the distance of the knife from the edge of the sole may be
regulated at pleasure, or may be entirely withdrawn therefrom.
A lever is provided for lifting the knife out of the channel when necessary.
By the use of my invention simplicity, cheapness, and efficiency are ensured, and
the distance of the knife from the edge of the sole is regulated with precision by
the adjustable guide; the spring being capable of adjustment to the required.
strength, and the operation being performed without the aid of foot power.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
letters of reference indicate corresponding parts.
Fig. 1 is a side elevation, Fig. 2 is a sectional elevation, Figs. 3 and 11 are front
elevations, and the remainder of the figures are explanatory of the details.
a is the ordinary stand. b is a sleeve, cast in one with the stand, in which an
axle c is fitted. d is a handle for turning the axle by hand. e is a pulley or wheel
with a serrated edge all round, and which wheel is fast on the axle c, and turns
therewith. The lower part of the stand a is circular in section; but the upper
part a¹ is cast square or rectangular in section, in order that it may act as a guide
to the hollow block f. The block f is free to slide vertically upon a¹, but such
motion is governed by the lever g, the plate m, the spring k, and the screw i;
which latter is regulated by the fly-nut k, screwed to the rod ; this rod is
screwed into the guide a¹.
The block is surmounted by a plate m, secured thereto by screws; and,
by means of the additional screw i, the distance between this plate m and the
guide a¹ can be regulated, as desired, to govern the depth of cut to be made in
the leather sole.
The lever g is shewn in Figs. 1, 2, 3, and 7. When this lever is raised to the
position shewn in solid lines (see Fig. 3) the curved portion g¹ (Fig. 7) rests upon
the sleeve b, and raises the block f to the position shewn in the drawings; in
which position the apparatus is ready to receive the sole to be channelled. The

page_text: lever is secured to the block f by the screw g³, upon which it turns. When
placed in the position shewn by dotted lines at g³ (Fig. 3) the block f is free to
descend as far as the screw i permits. n is a pressure wheel or pulley which presses
the leather sole down upon the serrations of the wheel e, and thereby grips the
same, and enables the wheel e to drive the sole under the knife t, (the position of
which is shewn by dotted lines in Figs. 1 and 3). The wheel n is secured to the
block by the screw n¹.
In order to govern the distance of the channel from the edge of the sole
horizontally, a thrust block o is fitted, as shewn. This thrust block with its
spindle, spring and nut is seen in position in Figs. 1 and 2, and is shewn enlarged
in Figs. 8, 9 and 10. o is the thrust block, p is the spindle, g the spring, and r the
nut. Fig. 8 is a side view, Fig. 9 a plan view, and Fig. 10 a front view of the
thrust block and spindle. By means of the screw-nut the distance of the thrust
block o from the guide a¹, can be regulated, and, by pressing the waist of the sole
against this thrust block, the distance of the channel from the edge can be
increased, such distance being diminished by removing the pressure when the
stouter portions of the sole are being channelled.
A vertical plate s is fixed to the front of the block f by screws 8¹. This plate is
shewn, enlarged, in Fig. 4. This plate serves to hold the channelling knife t in
position, as shewn by dotted lines in Figs. 1 and 3. A side view of the knife t
(enlarged) is shewn in Fig. 5, and a front view of the same in Fig. 6.
The dotted lines u v in Fig. 3, shew the position in which the sole is placed,
previously to the channel being made. The lever g having been raised, as shewn,
the wheel and knife t are also raised thereby. The sole uv is then inserted.
The lever g is then lowered to the position g³. This allows the wheel n to press
upon the leather, and the knife t to enter the same. The handle d is then turned,
whereby the sole is propelled from u towards v, the knife cutting the channel at
the same time. When the channel has been completed, all round the sole, the
block fis raised by the lever y and the sole is removed.
I sometimes form the plate s as shewn in Fig. 11. The wheel n is carried
by the plate 8, to which it is fitted by the screw n¹. In this arrangement the
channelling knife t may be placed in a vertical position behind the plate 8, as
shewn in Fig. 11.
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
1. The application and use, in channelling machines, of the thrust block o,
spindle p, spring q,. and nut r, for the purpose of governing, regulating, and
varying the distance of the channel from the edge of the sole, substantially as
herein before described and shewn on the drawings.
2. The general construction, combination and arrangement, of the several and
respective parts, together forming ny improvements in the construction of
machines for channelling the soles of boots and shoes and analogous purposes,
substantially as herein before described and shewn on the drawings.
