MARK THOMAS DENNE, 9 Haughton Road, Handsworth, Birmingham, Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to machines for channeling soles of Boots & Shoes, and
consists of an improved method of feeding the work to be operated upon and of
adjusting the distance of the cutter or knife from the edge of the sole, as the
sole is fed forward whereby I am enabled to obtain a channel which is cut ⚫
truely with the upper of the shoe with facility and at the same time to compress
the edge to give greater firmness during the subsequent operations.
In carrying my invention into effect when applied to channeling while the
sole is in position upon the shoe and after it has been rounded. I employ a wheel
with a serrated edge revolved at a constant rate of speed in a horizontal plane
and adapted to engage with the edge of the sole and urge it forward, in combina-
tion with a second wheel also with a serrated edge; but revolving in a vertical
plane so that it may run upon the upper surface of the sole between its edge and
the channel cutter or knife. The said cutter or knife is adjustably secured to
a supporting block-in such a way that it projects downwards beyond the periphery
of the vertical feed wheel, to the distance necessary for the depth of channel
required. The adjustment in the distance of the channel cutter or knife from the
edge, while the machine is being operated is effected by moving the vertical feed
wheel together with the knife, forward; when channelling the waist, to a stop,
against the action of a spring by means of a foot pedal. The work is carried
upon a wheel revolving in a horizontal plane beneath the first before mentioned
feed wheel; with its periphery projecting beyond the serrated edge; and adapted
to run upon the welt and give support to the work, against the action of a spring,
which tends to depress the upper portion of the frame of the machine which is
pivoted, with the vertical feed wheel and knife, and to keep it in contact with the
sole.
Improvements in Channeling Machines for Boots and Shoes,
I, MARK THOMAS DENNE, of 9 Haughton Road, Handsworth, in the County of
Stafford, Engineer, do hereby declare the nature of this invention and in what
Price 1

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement: -
My invention relates to machines for channelling the soles of boots and shoes,
and consists of an improved method of feeding the work to be operated upon, and
of adjusting the distance of the cutter or knife from the edge of the sole as the
sole is fed forward, whereby I am enabled to obtain with facility a channel which
is cut true with the upper of the shoe, and at the same time to compress the
edges, so as to give greater firmness during the subsequent operations.
The accompanying drawings illustrate a channelling machine constructed in
accordance with my said invention for the purpose of channelling the sole while 1
in position on the shoe, and after it has been "rounded."
Fig. 1 is a side elevation of the machine.
Fig. 2 is a section through the feeding, guiding, and work-supporting wheels,
and,
Fig. 3 is a section through the knife and knife-holder, on line x-x of Fig. 2.
Similar letters indicate corresponding parts in all the drawings.
In a suitable bearing A' in the frame A of the machine is a rotating sleeve-C,
having a flange C₁ on which is secured a vertical feed wheel D; driven by the
pin C, and having its periphery serrated as shown. To the said sleeve is secured,
by a feather or key sliding in a key-way, a worm-wheel G driven by the worm H,
on the spindle H of the band pulley H². In bearings A³, also in the frame of
the machine, is a spindle Me driven through the worm-wheel O by the worm P
on the spindle P¹ of the band pulley P. On the said spindle M2 is a horizontal
serrated feed-wheel M, fixed thereon by the pin m³, and a smooth work-supporting
wheel M¹ having a key or feather engaging in the keyway m² in the spindle, and
capable of sliding up and down so as to accommodate various thicknesses of sole.
Under the said work-supporting wheel M³ is a loose collar m, having pins m³
engaging in the forked end of the lever N, which lever is capable of oscillating
on the
pin N, but normally presses the collar m and the work-supporting wheel Mi
upwards owing to the downward pull of the spring N2, attached to the end n of the
lever N. The said spring is adjusted by the nut N on the screwed portion of
the drawbolt N3, and on the lever N is also an arm n', having a handle n², by
which to lower the wheel M and thus facilitate the insertion of the work between
it and the wheel D. The worm-wheel O is provided with a key or feather engaging
in the keyway m¹, and is prevented from moving vertically by the cheeks or
flanges A on the frame A.
Within the sleeve C is a knife-holder B, carrying at one end the block B³, in
which is secured the adjustable curved knife b, and at the other end a collar B¹
fixed by a screw B³, and having a slot B³ connected by the pin F to the bell-
orank lever J, whereby the said knife-holder B is prevented from rotating.
The knife-holder is secured within the sleeve at one end by the collar B¹, and
at the other end by the inner face of the knife-block B5, bearing against the end
of the sleeve. The knife-block serves also to secure the feed-wheel D on the
sleeve C, so that by a movement of the lever J on the pin J¹, the knife-holder
with the sleeve may travel outwards longitudinally so as to vary the distance
between the channel and the edge of the sole while the channel is being cut.
The lever J is operated, by a suitable treadle, through the rod K, provided
with adjustable stop-nuts and working between the lugs A5, but the sleeve is
normally kept inwards by the spring K³, which is also adjustable, by means of
the nut K³.
On the shouldered end B of the knife-holder B is revolubly mounted, a smooth
edged guide wheel E, secured in position by the screw E¹. The knife bis
preferably of dovetail section and secured in the groove of the holder B by the
clamp plate B6, and screws 6², so as to be adjustable. The band pulleys H³, P²,
are driven by the band h, which passes over a carrier pulley L.
Although I have described my invention only as applied to machines for

page_text: channelling the sole while in position on the shoe, obviously I may adapt the
same to other channelling machines, such as those employed for channelling the
soles before attaching them to the uppers, and I may vary the same to suit any
particular or peculiar requirements, without departing from the essential features
of the invention.
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. In a channelling machine, the means for adjusting the distance of the
channel from the edge of the sole while in operation, substantially as described.
2. In a channelling machine, the combination with a vertical feed wheel such
as D, and a guard such as E, of the adjustable curved knife b, substantially as
described.
3. In a channelling machine, the combination, with the horizontal feed wheel M,
of the self-adjusting wheel M³, substantially as described.
4. The construction and arrangement of the improved channelling machine,
substantially as and for the purposes described, and illustrated in the accom-
panying drawings.
