page_text: gure 10 represents an enlarged side view of the bending rolis.
Figure 11 represents a top view of the same.
Like letters indicate corresponding parts throughout the drawings.
In Figures 1 to 7 inclusive, showing the feather edging and channelling devices,
a represents the supporting frame in which is journalled the shaft 6 of the work
supporting wheel or bed roll c, on which the sole is supported while being feather
edged and channelled. d represents the feed wheel which is mounted on a shaft e
journalled in hearings in a yoke or frame ſ, which is pivoted at g to the supporting
frame a.
The feed wheel and bed roll are positively rotated in opposite directions by a pinion
on a shaft i journalled in the yoke below the pivot g; said shaft having a crank j.
The pinion meshes with a gear k attached to the feed wheel shaft e and said gear
meshes also with a gear on the roll shaft b. The yoke or frame f, in which the
feed wheel shaft is journalled, is adapted to swing in a substantially vertical direction
on its pivot g to permit the feed wheel to rise and fall. Said yoke is pressed down-
wardly by a spring m enclosed in a housing a on the supporting frame; said spring
giving the feed wheel a yielding pressure on the work. To enable the operator to
raise the feed wheel for the insertion and removal of the work, I provide a lever o,
which is pivoted at p, to the supporting frame and has a shorter arm bearing against
the under side of the yoke f, and a longer arm which is connected by a rod
treadle not shown. The depression of said treadle by the operator's foot raises the
shorter arm of the lever and with the yoke fand feed-wheel d.

represents the edge bevelling or feathering knife, which has an inclined cutting
edge arranged to cut a bevelled strip from the upper surface of a sole resting on the
The shank of said knife is suitably secured to a slide or holder s, which is
adapted to move vertically in guides in an arm or bracket t affixed to the supporting
frame; said slide being held down with a yielding pressure by a spring u interposed
between an adjusting screw in a fixed aro a' on the supporting frame and a nut b
on a rod w attached to and projecting upwardly from the slide, said rod entering an
orifice in the adjusting screw and being adapted to move up and down therein. The
extent of the depression of the knife holder by the spring may be regulated by a
screw c¹, which is inserted in a part of the supporting frame under the knife holder s
and serves as an adjustable stop or rest on which said holder bears.

The holders may be raised independently at the will of the operator by means of a
lever d¹ pivoted to the frame of the machine, a rod e¹ interposed between one arm of
said lever and the knife holder, and a rod g¹ connecting the other arm of said lever
with a treadle (not shown), the depression of which raises the rod e¹ and the knife,
holder.
I have also provided for the raising of the knife holder s simultaneously with the
feed wheel, and to this end I have provided the pivoted yoke or frame which supports
the feed wheel with an arm f, having at its upper end a lip through a hole in
which the rod w of the knife holder s passes, as shown in Figure 5. A nutjon said
rod bears on the upper surface of said lip 1, so that when the yoke fis raised as above
described by the lever to raise the feed wheel, the knife holder s is also raised. The
knife holder has no positive engagement with the yoke and is therefore free to be
raised independently by the lover d' when it is desirable to raise the knife without
raising the feed wheel."
4 represents a foot or gauge attached to the yokef by screws passing through
slots mm in the shank of said foot. The gauge is formed to be on the upper surface
of a sole beside the feed wheel and it limits the penetration or sinking of the teeth of
the feed wheel into the sole. The gauge is vertically adjustable by means of the
slots m and screws . » represents an edge guide which is adapted to project over
the bed roll c and guide the edge of the sole. Said guide is formed on a lever o¹,
which is pivoted at p to the supporting frame, and may be adjusted by means of two
stop screws which may be arranged to hold the lever rigidly or to give it any
desired amount of play. The guide n may therefore be held at any desired distance
from the feed wheel. When the stops are adjusted to permit the lever o to

page_text: oscillate, a rods may be connected to said lever, said rod being connected with a
treadle and normally raised by a spring so as to hold the guide over the bed roll,
as shown in Figure 1, the guide being drawn back by the depression of the rod s¹.
A represents the channelling knife, which is arranged diagonally in a slide or
holder B, to which the shank of the said knife is attached in any suitable manner.
Said holder is fitted to slide vertically in guides in the arm or bracket t and is
pressed downwardly by a spring C interposed between an adjusting screw D in the
arm and a collar E on a rod F which is attached to the knife holder A. The
depression of the holder A and the normal height of the channelling knife is
regulated by a screw G in a ear H on the holder B, said screw being arranged to
bear on the arm or bracket and constituting an adjustable stop which limits the
downward movement of the holder B and the channelling knife, so that the latter can
be adjusted to cut a channel of any desired depth. An ear or lug J on the arm of
the yoke or frame fis arranged to bear on the under side of a projection K on the
channelling knife holder B, so that the upward movement of the yoke / will lift the
channelling knife.

It will be seen therefore that while the feed wheel, bevelling knife and channelling
knife A are raised simultaneously by the lever o to permit the ready insertion and
removal of the work, the bevelling knife may be raised independently of the feed
wheel and channelling knife and the channelling knife may be vertically adjusted
independently. The bovelling knife may also he vertically adjusted independently by
means of the stop screw.
The described independent adjustments of the bevelling and channelling knives
adapt them to soles of various thicknesses, and enable the bevel-formed by the
knife to extend entirely to the bottom surface of the sole, as shown in Figure 6, or
only partly to the bottom surface, as shown in Figure 7.
A foot or gauge L is attached to the channelling knife holder, its lower portion
being arranged to bear upon the upper surface of the sole in advance of the
channelling knife. Said gauge is adjustable vertically like the

I am aware that the combination in a sole channelling machine of a bed roll, a
feed wheel, a vertically movable yoke or frame supporting the feed wheel shaft and
held down by a spring, and a lever whereby the yoke may be raised to elevate the
feed wheel, is not new, and I do not therefore claim such combination.
Referring to Figures 8, 9, 10 and 11, which show the solo moulding portion of
the mechanism, all represents a supporting frame or standard having its upper
portion divided into two arms 2, 3, one of which is provided with an adjustable
socket or bearing which is externally screw threaded and is screwed into an
internally threaded cavity in the arm 2, by which means the said bearing is made
adjustable horizontally. c represents a shaft which is journalled in said adjustable
bearing and in a bearing in the arm 3 of the standard. Said shaft is provided with
collars or enlargements del which bear against the ends of the adjustable bearing 6,
so that the shaft is necessarily adjusted lengthwise by any adjustment of the bearing b
One of said collars is the hub of a crank 1, by which the shaft e" is rotated, while
the other collar is a gear wheel e which meshes with another gear wheel ell on the
upper shaft f
a
grepresents a yoke or frame, one end of which is pivoted at " to the arm 2, of
the standard a. The other end of said yoke is adapted to rise and fall in a slot or
guide in the arm 3, and is held down in said slot with a yielding pressure by
spring located in a casing attached to the arm 3. 11 represents a shaft which
is journalled in bearings in the yoke g" and normally extends substantially parallel
with the shaft e".
n", o represent frusto-conical rolls affixed respectively to the swinging end of the
shaft and to the corresponding end of the shaft c", the larger end of each roll
being opposite the smaller end of the other roll, as shown. The roll n¹¹ is provided at
its smaller end with a flange n which overlaps the larger end of the roll o" when
both rolls are in their normal position. The rolls are so arranged that there is a
space between the peripheries of the rolls and between the base of the roll o" and the

page_text: flange of the roll n¹¹, so that the edge of a sole may be passed between the two rolls
and between the flange and the base of the roll o" and be bent near its edge by said
flange and base, as shown in Figure 10.
The longitudinal adjustability of the shaft c" by means of the adjustable bearing",
enables the space between the base of the roll oil and the flange to be adjusted to
the thickness of the sole to be operated upon, while the yielding movement which is
given to the roll n by the pivoted yoke and the spring enables the periphery of
said roll to conform to any thickness that may be interposed between it and the lower
roll o¹¹.
To enable the operator to raise the upper roll, I provide a lever 11 which is pivoted
at & to an ear on the supporting standard and bears at one end against the yoke g
The other end of said lever is connected by a rod with a treadle (not shown)
whereby the rod may be depressed and the yoke " with the roll n" raised.
represents a guide formed on the yoke and projecting downwardly therefrom
to support the edge of the sole in advance of the rolls n o. The outer surface of
the guide is curved so that it conforms to the curvature which the sole assumes
at the point where it is being bent, as shown in Figure 11.
The shafts cfare connected by the gears en el and may be rotated by the
crank d
