I, FREDERICK CUTLAN, Engineer, of Castle Hill, Wellingborough, in the County
of Northampton, do hereby declare the nature of this invention to be as follows:-
This invention relates to "channelling" machines suitable particularly for
'channelling" soles of boots and shoes. The chief features of the machine are
as follows:
Upon any suitable standard or frame which may be adapted to be bolted down
in or upon an ordinary working bench is carried a sliding frame in suitable
bearings of which is a shaft preferably horizontal having a hand wheel or belt
pulley by which it is rotated. The sliding frame is provided with a pin or
projection which enters a groove in a cam plate pivoted upon the standard and
controlled by preferably a foot treadle or other suitable means, so that when
the cam is in its normal position in which it can be retained by a suitable spring,
the sliding frame is in one position, say its backward position, and when the
cam is moved, it is moved into another position say its forward or any inter-
mediate position. The standard also carries another cam arrangement adapted
to be operated by hand by which the forward or operated end of the sliding frame
can be raised or lowered to accommodate varying thicknesses of leather or cut.
The forward end of the shaft carries a propelling wheel which is preferably
toothed to press upon or into the leather for the purpose of moving it forward.
The leather lies and is gripped between this wheel and a horizontal rotating table
which rotates as the leather travels. This table can be raised or lowered by a
suitable screw, cam, or other means, preferably a screw with a milled head,
and a lock nut.
The forward end of the sliding frame carries a yoke or other device to which
is secured one of the knives or cutting edges, the other knife or cutting edge
being secured in or upon the sliding frame, both knives being capable of ready
removal when required.

This invention relates to "channelling" machines suitable particularly for

The forward end of the shaft carries a propelling wheel which is preferably

The leather lies and is gripped between this wheel and a horizontal rotating table
which rotates as the leather travels. This table can be raised or lowered by a
suitable screw, cam, or other means, preferably a screw with a milled head,
and a lock nut.
The forward end of the sliding frame carries a yoke or other device to which
is secured one of the knives or cutting edges, the other knife or cutting edge
being secured in or upon the sliding frame, both knives being capable of ready
removal when required.
The drawings illustrate one construction of machine according to this invention,
Figure 1 is a front elevation of the machine partly in section, the sliding frame
being in the raised position,
Fig. 2 an end view, and
Figure 3 a rear view of the operative portions of the machine showing a piece
of leather in course of being "channelled" by the machine.
Like letters indicate like parts throughout the drawings.
The standard or frame of the machine is shown at A and has at its base a
flange A by which it may be bolted down upon an ordinary bench. The upper
portion of the standard A supports a sliding frame B in which are the bearings C
for the driving shaft C, the driving shaft being provided at the left hand end
of the machine with a hand wheel C² by which it is operated. The frame B
is attached to the standard A by a pin B¹ which fits tightly into a hole in the
frame B, and engages in slots A2 which are formed in the side walls A³ of the
groove A in the standard A in which the frame B slides.
The pin B is prolonged on the front side of the machine and enters a cam
groove D in a cam D, the cam being pivotally connected to the standard A
at D and being provided with a rod D3 by which it may be drawn downwards,
and a spring D by which it is normally held in its uppermost position. The
rod D³ may be provided with an eye D³ at its lower end, by which it may
conveniently be connected with a treadle.
"
At the right hand end of the machine, the side walls A³ of the groove A* are
extended upwards and serve to support a cross plate A5. At this end of the
machine there is a rod E. pivotted at E¹ to the frame B, so as to be capable of
swinging about an axis substantially at right angles to the direction of the
sliding motion of which the frame B",
can partake. This pin passes up freely
through a hole A6 in the plate A5 and is encircled at its upper end by a cam F.
The hole A is sufficiently large as compared with the rod E for the latter to he
allowed to partake of the desired swinging motion about the pin E. A spring
encircles the rod E below the plate A5 and is in compression between the said

page_text: plate and the upper surface of the frame B. The end of the frame B to which
the rod E is attached may be raised against the pressure of the spring E³, by
means of the cam F, the cam slot F of which acts upon a pin E³ in the rod E.
To this end of the frame B is secured a yoke or bracket G which serves to
carry one of the knives or cutting edges H. This knife is preferably curved as
shown in the drawings. Another knife H' (seen best in Figure 3) is carried
at the right hand end of the frame B by being embedded in a groove therein
and secured in position by a wedge I, plate II and screw 1%, or in any other
convenient manner.
Between the two knives is a toothed feed wheel K which is carried upon the
extremity of the shaft C with which it rotates. A spring K attached to the
frame B, serves to keep the leather pressed upon the table L, so that it is kept
flat while being fed on to the knives.
Below the knives is a projection A' of the frame A which supports a mush-
room-like table L. The stem L' of the table enters the projection A', which
latter also carries a screw M with milled head M and lock nut Me which bears
upon the stem L' of the table and serves to adjust its height. Upon the frame A
in the groove A* and close to the edge of the table L is secured a guide P which
guides the work when it is being passed through the machine.
The operation of the machine is as follows:-
The height of the table having been adjusted to suit the thickness of material
to be channelled so as to give a cut of the required depth, the end of the frame B
is raised by means of the cam F as shown in Figures 1 and 2 and the material
placed below the knives upon the table. The cam F is then turned so as to
allow the spring E² to depress the end of the frame as shown in Figure 3 and
thus insert the points of the knives in the material which is lettered Q. The
hand wheel C is then rotated by the workman's left hand while he with his right
guides the material through the machine by keeping it pressed against the fence
or guide P, the table rotating with the leather, as the latter passes the knives.
If the operator desires to cut the channel in the material at a greater distance
from its edge, he presses upon the treadle connected to the rod D3, thus over-
coming the pressure of the spring and lowering the cam 1 about its pivot Da
by which means the frame B is caused to travel in the groove. A³, and the
knives H H and feed wheel K, to travel away from the guide P. When the
operator releases the pressure upon the treadle, the spring D₁ returns the cam
to its upper position and brings the frame B back to its normal position. The
advantage of this construction over that commonly employed in channelling
machines is that the knives are moved relatively to the guide and table to vary
the distance of the cut from the edge of the material instead of the guide and
material being moved relatively to the table and knives, by which latter method
the leather has to be dragged over the surface of the table.
It will be seen that the knives may receive motion in either of two directions
namely, motion horizontally away from the fence to vary the distance of the cut
in the surface of the work from the edge of the work, and motion perpendicularly
away from the fence and the table, which in the machine illustrated is intended
to withdraw the knives from the work. The former motion may conveniently
be described as across the work" and the latter as perpendicular to the work."
In the example illustrated both these motions are effected by cams; that
across the work" by the cam D and that perpendicular to the work" by
the cam F.
"
**
The motion of the rod E about its pivot E¹ is only required through a very
small range and is provided for by making the hole A6 sufficiently large relatively
to the rod as before stated and by allowing the cam F to tilt more or less on to its
edge or if preferred by similarly allowing sufficient play of the rod E in the hole
in the cam F through which it passes.
It should be stated that this invention is not limited to the precise construction
of machine herein before described and illustrated in the accompanying drawings

page_text: but that many modifications may obviously be made in that construction without
departing from the spirit of this invention. As an instance of such modifications
the frame B may be hinged to a sliding block, the sliding block being operated
by the cam D so that the frame B will in this case also be capable of receiving
the two required motions. Or again instead of the cam D a rod or other flexible
tie may be passed over a pulley attached to the frame of the machine and the
frame B be pulled by this rod into its required position against the action of
the spring, which returns it to its normal position. If preferred the machine
may be driven by power and for that purpose be provided with a belt pulley or
it may be driven by treadle mechanism. If preferred the knives may be replaced
by a single tool or knife having two cutting points, or again only one knife
may be carried by the sliding block the other being otherwise adjustable.
Having now particularly described and ascertained the nature of the said
invention. and in what manner the same is to be performed, I declare that what
I claim is:-
-
1. A channelling machine in which the knife or knives are adjustable relatively
to a stationary work-guide during the operation of the machine.
2. In a channelling machine the combination with a rotary support for the
work of a stationary guide adjacent thereto and a knife or knives adjustable
relatively to the stationary guide during the operation of the machine.
3. A channelling machine in which a movable frame carrying the knife or
knives and the feed mechanism is adjustable across the work during the operation
of the machine.
4. A channelling machine in which a movable frame carrying the knife or
knives and the feed mechanism is adjustable relatively to a stationary work-
guide across the work and also perpendicularly thereto during the operation of
the machine.
5. A channelling machine in which a frame carrying the knife or knives and
the feed mechanism is pivotted on sliding pivots in the main frame A for the
purpose described.
6. A channelling machine in which a frame carrying the knife or knives and
the feed mechanism is pivotted in the main frame A so as to rise and fall relatively
to the work-support.
7. In a channelling machine the combination with the moving frame B of a
lifting link such as E pivotted thereto and operated by a cam F substantially
as and for the purpose described.
8. The complete channelling machine substantially as described and illustrated
in the accompanying drawings.
