Improvements in Machines for Trimming and Channelling the
Soles of Boots and Shoes.
We, ZACHARY TAYLOR FRENCH, of Wabau Street, and WILLIAM CHRISTIAN MEYER,
of Peter Parley Road, both of Boston, Massachusetts, United States of America,
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:-
In English Patent No. 3,497 of 1896, machines were shown for operating upon the
soles of boots and shoes, and one of the essential novel features embodied in said
machine was the means employed for guiding the boot or shoe while the sole was being
operated upon.
The machine shown was especially designed for trimming and channelling the soles
of lasted boots and shoes, while secured to or upon the last, and the guiding device
was such that the width of the projecting edge of the sole beyond the upper could he
varied, as for instance, it could be made wider all around the fore-part than along the
shank portion, or it could be made widest along the outside ball portion, and of less
width around the toe and inside ball portion, and of least width along the shank
portions.
This invention is intended as an improvement upon the machine shown in said
Letters Patent, and consists essentially in certain improvements in the means
employed for guiding the boot or shoe while its sole is being operated upon, as for
instance while being trimmed and channelled, if trimming and channelling knives are
provided.
In the machine shown in the aforesaid Letters Patent two independent guides were
employed, one of which was used to the exclusion of the other to guide the lasted
boot or shoe along the shank portions, and the other was adapted to be brought into
use to guide the lasted boot or shoe along or around the fore-part, and while guiding
the boot or shoe along such portion it acted to the exclusion of the shank guide. The
former guide, which acted as the shank guide, was stationarily supported, and the
latter guide which acted as the fore-part guide was made movable, and said movable
guide when brought into engagement with the lasted boot or shoe was adapted
to positively or bodily move the boot or shoe with relation to the trimming and
channelling knives, and away from the shank guide, and when removed from engage-
ment with the lasted boot or shoe permitted said boot or shce to be positively or
bodily moved towards and into engagement with said shauk guide.
As the work is thus moved away from the shank guide, the latter still bears upon
the projecting welt or sole, near its outer edge, and consequently a ridge or
depressed line is formed which is very objectionable.
This invention has for its object to overcome this difficulty, and in doing so the
shank guide heretofore made stationary, is made movable, so as to follow more closely in
the crease all around the shoe, or that portion thereof which is being trimmed and
channelled, and being thus made movable it may be employed as the means for
positively or bodily moving the work with relation to the tools at any desired part of
the operation.
Therefore in accordance with our present invention two movable guides or supports

page_text: are employed, one of which acts continuously along the shank portions and fore-
part and the other acts around the fore-part only.
These two guides will in some cases act conjunctively, as guides, around the
fore-part, and in other cases the last guide will act to the exclusion of the shank
guide around said fore-part, the shank guide at such time not bottoming in the
crease, or entering it sufficiently to serve as a guide, yet at such time it is still a
support for the work or welt, and as such acts conjunctively with the last guide.
The continuously acting guide or support may form a co-operative part of the
clamp-feeding mechanism for the work, as in the applications above referred to, and
being made movable so as to continually enter the crease more or less better enables
it to perform such additional function.
The invention is herein embodied in a machine having trimming and channelling
knives adapted to trim and channel the sole of the lasted boot or shoe, as it is fed
along and is adapted to be used for trimming both plain and extension edges.
In the accompanying drawings-
Figure 1, shows in front elevation a sole trimming and channeling machine
embodying our invention.

for operating the two guides.

Figure 8, a diagram view of a Baltimore edged sole showing in dotted lines the
outline of the last; and
Figure 9, a vertical section similar to Figure 5, showing the actuating arm for the
continuously acting guide or support.
The trimming knife e Figures 3 and 4 is attached in a removable manner to the
lower end of an arm el projecting from a hub e2 Figure 4, mounted upon a shaft d³,
said arın e¹ being connected by a link e with an eccentric strap which embraces an
eccentric disk secured to the main shaft C, so that as said shaft rotates the knife e will
be oscillated in a direction toward and from the operator, acting upon the bottom of
the projecting portion or edge of the sole of a lasted boot or shoe.
The guide or work-support a is attached to the forward end of an arm a 20
Figures 3, 5 & 9, pivoted at a¹ to an ear a22 on the frame, said guide or work-support
being represented as a loop (see Figure 1) and made more or less tapering at its
lower end, thereby adapting it to enter the in-seam or crease at the welt-side of the
sole.
This guide or work-support a is designed to continuously act all around the boot
or shoe, or that portion thereof which is being operated upon, and in this respect
differs from the work-support in the aforesaid application wherein it was stationarily
supported, and this movable guide or work-support herein forms an essential feature
of novelty.
The pivoted arm a20 carrying the guide or work-support a is supported in elevated
position by means of a strong spring a2, Figure 4, and its upward movement is
limited by a stop a², formed on the frame, against which the forward end of the arm
strikes.
Intermittingly operated clamp-feeding mechanism is provided for feeding the work
along, consisting of a yielding vibrating sole-support 1, Figures 1 and 5, adapted to
bear upon or against the bottom of the sole, and a four-motion plate d adapted to act
against the opposite or welt-side of the sole.
The plate d, herein serves as a cutting block against which the oscillating trimming

page_text: knife e operates, in addition to forming a co-operative part of the clamp-feeding
mechanism.
The sole-support 65 carries the channel knife b, Figure 5.
The work is fed along by the feeding plate d and vibrating sole-support 65, which
together act as a clamp feeding device, and when said feeding plate & returns for a
new grip on the work, the movable guide or work-support will serve as the support
for the welt-side of the sole, or face side of the welt, it co-operating with the sole
support b in holding the work during such time. Thus the movable guide or work-
support a, not only acts as a guide but also as a device for assisting in holding the
work while the feeding plate returns for a new grip.
Another guide or guiding device f Figures 1 & 4 is attached in a more or less
yielding and adjustable manner to an arm f¹, as for instance it may be pivotally
connected at f20 to a block f21, adjustably secured to said arm by a screw f22 passing
through a slot in said block, it being held pressed in a right angular position to the
arm by means of a spring f23.
This guide f is adapted to be normally held in elevated position, out of engagement
with the lasted boot or shoe, as shewn in Figures 1 & 3, and to be brought into
engagement with said boot or shoe around the fore-part only, as shown in
Figures 4 and 5.
The guide arm f¹ is pivoted at f2 and has attached to it a chain which is connected
to a treadle; so that by depression of the treadle the guide may be brought into
operative position, and whenever it is thus brought into operative position said guide f
will act in conjunction with the guide or support a, or to the exclusion thereof
depending upon its relative position thereto.
The fore-part guide f is provided with suitable means whereby its movements
are automatically controlled, and herein substantially the same automatic mechanism
is shown as appears in the Letters Patent above referred to, to which reference may
be had.
As the particular construction of this automatic mechanism forms no part of my
present invention it is not herein illustrated in detail, but sufficiently to enable
our present invention to be understood, and in general it may be described as
follows:-
The guide arm f¹ has an upward extension f12 bearing a cam roll f¹³, and has also
at its upper end a latch f¹ (Figs. 1 and 2) inovable in suitable bearings provided for
it in a radial direction toward the shaft d³.
This latch is herein shewn as a pin, having a beveled lower end, and a cross piece
or pin fl Figures 4, 5 & 9 at its upper end, and inside the bearing containing said
pin f a spring (not shewn) is placed which encircles the pin, and is connected with
it in such a manner as to depress it.
The upper end of the extension f12 is shouldered or cut away, presenting an upper
end and a lower rest for the cross piece ₤15.
When the latch or pin is depressed the cross piece f15 enters said cut away
portion, and bears upon the lower rest, but when raised or withdrawn and given a
quarter turn the cross piece f¹³ will bear upon the upper rest, thereby holding the
pin fin its elevated position.
The latch is made reversible in its bearings, so that its beveled end may be
turned in one or the other direction, according as it may be necessary.
The rotary reciprocating or oscillating knife-carrying-hub or sleeve e² is extended
along the shaft 3, and has upon its sleeve-like extension a notched collar or rim n.
Figures 1 and 2, provided with sleeve-like extensions upon both sides, upon one of
which a clamping ring m is placed which acts to frictionally bind the notched collar n
to the rotary reciprocating sleeve.
A clamping ring embraces the opposite sleeve-like extension and has formed upon
it two cains m² and h.
The notched part of the collar is located beneath the latch or pin f¹, and the
cain m² beneath the cam roll f13.
The arm f' carrying the guide f is normally held in its elevated position as shown

page_text: in Figure 3, and when it is moved into position to be used as the fore-part or last
guide, the cam roll f13 will be brought to bear upon the cam m², as shewn in Figure 4.
While the latch 14 remains in its elevated position in its bearing, the notched collar n
is not engaged, and the cam roll f13 will at such time rest idly upon the cam m², and
the relative position of the guide f, and trimming and channelling knives, will remain
the same, but as soon as the latch is turned in one or the other direction, it descends
and its lower beveled end enters the notches cut in the part n, and as the sleeve
bearing said part n oscillates; the cam is intermittingly rotated, until the stop m³ is
brought to bear against the cam roll.
During the travel or progress of the cam m² the guide f is gradually moved
relatively to the trimming and channelling knives.
When the latch f¹ is in one position, and the cain m² turned in one direction, the
guide will be automatically raised, and when the position of the latch f14 is reversed
and the cam m² turned in the opposite direction the guide f will be automatically
lowered.
These two movements are required for working upon left and right shoes.
Means are provided for automatically controlling the reversal of the latch f14
which consists of a rod p arranged horizontally in bearings p' secured to the frame-
work, having affixed to it a finger p², the upper side or face of which is beveled in
opposite ways, and this finger projects towards the latch, but is located beneath the
cross piece or pin f15, when the latch is in its elevated position in its bearing, and is
arranged to be engaged by said pin f15 as will be described.
The rod p Figure 1 is movable longitudinally in its bearings in order that the
finger p² may occupy a position with one or the other beveled face directly beneath
the pin f15 on the latch f, and said rod is also free to be turned or rocked that the
finger 2 may be lifted to permit the return of the pin.
A detent w, Figure 1, is pivoted to a stud 5, Figures 1 and 3 projecting from
a part po on the rod p, but connected and movable longitudinally with said rod,
said detent engaging a stop w¹ on the frame, when the rod is in its extreme left
hand position, a spring w2 being connected to said detent to draw it in.
A spring w³ encircles the rod p, and is connected at one end to the frame, and at
the other end to the finger p², or it may be the rod, the action of which is to move
the rod p and its attached finger p² toward the right whenever the detent w dis-
engages the plate w'.
An arm is secured to the shaft of the guide arm f¹ which has a spring pressed
latch at its upper end, which as the guide arm is depressed strikes and dis-
engages the detent w, to thereby allow the rod p to move toward the right.
The rod p and its attached parts are afterwards moved toward the left or
restored to their normal position by the operator pressing upon the knob 2015.
Assuming that the parts are in the position shewn in Figure 1, and that the
operator desires to vary the width of the sole; he depresses the arm f¹ by means of
a treadle connected thereto, and in doing so the piu f15 strikes the right beveled
face of the finger p², and moving along said face is lifted and also turned
substantially a quarter of a revolution and the latch w5 then strikes the detent w,
disengaging it from the plate w¹ and the spring pressed rod p, thus released, is moved
towards the right, carrying with it the finger p², which is fixed to it, and the latter
during its passage strikes the pin fls and turns it further to the right, so that it will
fall into the cut away portion of the extension f12 and the latch f¹ is thus permitted
to descend and engage the notched collar.
The guide-actuating cam is then intermittingly turned.
It will be seen that the latch 14 is thus automatically turned one way by the act of
depressing the guide arm.
The guide arm is then elevated upon releasing the treadle.
When operating on the next shoe of the pair the guide arm is again depressed
at the desired time, and the pin f15 turned a quarter of a revolution by striking and
moving upon the left beveled face of the finger på, and then the rod p is pushed
toward the left by the operator striking upon the knob w, and during such

page_text: movement the finger p² bearing against the pin moves it sufficiently for the latch f¹+
to again drop into engagement with the notched collar, and the detent w will at such
time be moved into engagement with the cut away plate w¹.
Thus it will be seen that the latch + is reversed each time it is depressed or
caused to engage the notched collar.
The rod p is capable of being turned in its bearings, and has secured to and
projecting from it two short arms p, p, the arm 2 bearing the pin 5, and the arm
p bearing a pin p³, and when the rod p is in proper position for the finger p² to
co-operate with the latch f¹ the pin ps bears against the support p', but whenever
desired the rod p may be oscillated, the finger p² moved out of co-operative relation
with the latch fit, and at such time the pin 5 will bear against the support p¹.
The guide or support a is adapted to be moved by the guide arın or it may be the
guide and for the accomplishment of this purpose the guide a is herein shown as
having projecting from it a pin which lies in the path of movement of a block j¹
Figures 4, & 5 on the guide f and when the guide f is depressed said block j¹
will strike said pin j and move said guide a so that during the time the block j¹ is in
engagement with the pin j the two guides may be moved together.
And said guide or support a has another actuator, to be described, which is herein
shewn as operated by or in conjunction with the guide arm f¹.
As the guide arins 20 and f¹ are pivoted on different centres and the arm fl of
shortest radius, it will be seen that the guide f may be caused to advance slightly
beyond the guide or work-support a when depressed, and in such case the guide a
will become solely a support, the work being guided by the guide f.
In trimming Scotch edged soles, i.e. wherein the projecting edge all around the
fore-part is of substantially the same width, yet wider than the projecting edge along
the shank portion, the means above described, viz. :—the pin j and block j¹, on the
guide f, is all that is necessary as a means for operating the guide or support a, and
in such case the operation of these parts will be as follows:-the lasted shoe is held
up against the guide or support a and the sole is trimmed along the shank portion
and then the fore-part guide f is depressed and just as or about the time that it is
brought to bear upon or against the form or last its block j¹ will engage the pin j
and the two guides will be moved together, thereby bodily moving the shoe
transversely to the travel of the work, and away from the knives."
This movement is limited according to the distance that it is desired the sole shall
project.
As soon as the sole around the fore-part is trimmed the fore-part guide f will be
elevated and the guide or support a permitted to resume its normal elevated position,
and the work can be moved accordingly, and then the sole is trimmed along the
other shank portion.
The latch is not thrown into engagement with the notched wheel n when
trimming and channelling Scotch edged soles, but its cross piece f¹5 rests upon the
upper rest of the extension 12 and in such case when the fore-part guide f is
depressed the roll will rest idly upon the cam m².
By moving the guide or support a with the guide f around the fore-part it will be
seen that its lower end may continue to occupy the same position in the crease, as it
did along the shank portion, or if not will deeply enter the crease, and as a
consequence no ridge or line of depression is formed on the face of the welt, as in
cases where said guide is stationarily supported, and the work is moved in and out
with relation thereto and to the knives.
The guide f, it will be seen is made adjustable on its arm or support, so that
its relative position to the guide or support a may be determined, and this enables
us to so position the guides with relation to each other, that the fore-part guide f
may move the guide or support « to such an extent that while it may continuously
enter the crease it will not bottom therein, and the result in such case is that
the guide f is actually and exclusively the guide for the shoe around the fore-part
while the part a serves only as a support.

page_text: Such means of guiding the shoe we deem preferable to guiding by means of
a guiding device which bottoms in the crease, for in the latter case, the guiding
device follows the irregularities of the inseam and the edge of the sole is trimmed
accordingly, and furthermore if said guiding device is made so as to properly
enter the crease at the shank and guide the shoe, it does not well subserve the
purpose as
a guide around the fore-part, as it is liable to wedge in the crease
and strain the seam.
For trimming Baltimore edges soles, i.e. wherein the edge of the sole around
the. fore-part varies in width, being widest along the outside ball portion, the
treadle and the automatic mechanisin for moving the fore-part guide f and guide
or work-support a, as above described, are employed, and in addition thereto
independent means are provided for moving said guide or work-support a so that
the edge of the sole may be gradually widened between the shank and the widest
part of the outside ball portion when working on a left shoe, and the reverse
when working on a right shoe.
The independent means or mechanism herein shewn for accomplishing this result
consists of an actuating lever or arm g, Figures 2,4 and 9, loosely mounted upon a
pivot screw g¹ fixed to a block g² supported upon the end of the shaft f², and adjustable
diametrically in a bearing formed at the end of said shaft by means of an
adjusting screw g³ see Figure 6.
The pivot screw g¹ is adjustable from a position in line with the axis of the shaft f²,
as shewn in Figure 4, to a position remote from or eccentric to said axis, as shewn in
Figures 5 and 9. The actuating arm g is made long enough to reach the guide ar
arm a20
when the pivot g¹ is in line with the axis, and to move said guide arm when adjusted
eccentric thereto, the extent of such movement being in accordance with the
eccentricity of the pivot, and said actuating arm g has an upward extension g
projecting from the pivot screw g¹ more or less at right angles to the arm g, which is
adapted to be engaged by one arm g of a bell-crank lever pivoted at go to a bracket on
the frame, the other arm g' of said bell-crank lever having a friction roll which bears
upon a cam h, herein shown as made fast to or integral with the cam m².
As the fore-part guide-arm f is depressed its shaft 2 being turned, will cause the
actuating arm g, if its pivot is adjusted eccentrically, to descend and by pressing
upon the guide arm a20 will gradually depress the guide a until such time as the
roll f13 on the guide arm f¹ strikes the cam m², and the block will then engage
the pin j.
The latch f is then turned and depressed, and the cam h will then be intermittingly
rotated with the cam m2, and the bell-crank lever g7-95 will be turned on its pivot
by said cam h, turning the actuating arm g on its pivot, from the position shown in
Figure 5 to the position shown in Figure 9, thus throwing it out of engagement with
said guide arm a 20.
Attached to the actuating arm g is a weight 920, which holds it with its extension g'
pressed into engagement with the arm 95, and hence serves as the means of keeping
the arm g7 in engagement with the cam h.
As the actuating arm g is thus swung on its pivot, raising its attached weight,
g20 Figure 9, its lower engaging end soon passes by or out of engagement with the
guide arm a 20 at which time said guide arın a20 will be held down by the block j¹
engaging the pin j.
The guide arm a20 will then be restored to its normal elevated position, as the
fore-part guide f is raised or restored to its normal position.
In Figure 8 a diagram is shown of a "left" shoe, and in trimming such sole the
parts will operate in the manner just described, that is to say, the guide a will be
held in its normal elevated position while acting along the shank portion, say from
the point 51 to the point 52, then the fore-part guide f will be gradually depressed,
and as it descends the guide arm 20 will be gradually depressed by the actuating
arm g as the work moves along from the point 52 to the point 53, at which time the
fore-part guide f will have been brought into engagement with the last or form,

page_text: and the block j carried thereby will at such time be first brought into engagement
with the pin j.
The actuating arm g is then thrown out and the guide a will be held solely by the
guide f, after which the two guides a and f will gradually rise together as the work
progresses from the point 53 toward the toe, and until the cam m² ceases to move
the fore-part guide arm f, and then the fore-part guide ƒ may be removed from its
engagement with the lasted shoe by releasing the treadle.
A "left" shoe having thus been completed, it will be seen that the cam m² will
be left at the end of its throw or oscillatio 1, with the highest part directly beneath
the roll f13, and the actuating arm g will be thrown out, and the parts when in such
position are ready to act upon a
<< right" shoe.
In beginning the "right" shoe the guides a and f will be in their elevated
positions, as when beginning a "left" shoe, but the actuating arm g will be
thrown out as represented in Figure 9, and the work will be begun on the long shank
side.
The guide a will first work to the exclusion of the guide f, along the long shank
portion, and then the guide-arm fl will be depressed by the treadle until its roll f13
is brought into engagement with the cam m² at the highest part thereof, at which
time the block j¹ on the guide f will be brought into engagement with the pin jon
the guide a, and then as soon as it is desired to widen the projecting edge of the
welt or sole, as for instance just after turning the toe, the cam m² will be started or
caused to rotate and to gradually return to its former position, shown in Figure 3,
and the guide arm f¹ will, during the time that the cam is thus acting, gradually
descend and its block j¹ being in engagement with the pin j will gradually depress
the guide a conjunctively with said guide f, until the cam m² ceases to rotate, at
which point the bell-crank lever g7-g bearing on the can h falls into the open
place or space in said cam h thereby allowing the actuating arm g to return to the
position shown in Figure 5, hold the arm a20 down, and thereafter allow it to rise
gradually upon the ascent of the guide arm f.
This gradual conjunctive action of the guides caused by the actuating arm g takes
place in passing from the widest part of the ball to the shank, just reversely to that
described in a "left" shoe.
The extent of movement of the guide a which may be produced by the guide-
arm may be determined by adjustment of the actuating arm g toward and from
the axis of the shaft f2, and when the pivot screw gl of said actuating arın is
coincident with the axis of said shaft 2, depression of the fore-part guide f will
merely turn the pivot screw on its own axis and the actuating arm g will not engage
and move, the arm a20, so that for some classes of work this pivot screw may be
adjusted or set coincident with the axis of the shaft f².
We do not desire to limit our invention to any particular construction of mechanism
for operating the guide a thus independently of the other means herein shown for
operating it, as it is obvious that many different ways may be devised for accomplishing
this result.
The channel knife 6 Figures 1 and 5 is formed on or projects from a plate 63 which
is secured to a rising and falling block n' having formed on it rack-teeth n² and said
plate has a post 62 which has placed upon it a friction roll 65 of any suitable shape, and
as it is desirable that this friction roll shall be easily removable we have placed upon
the post b² beneath said roll a collar 650 having an ear 651 Figure 7 projecting laterally
from it which is bifurcated to receive the shank of a screw 652 Figures 5 and 7 which
projects from the lower end of the rising and falling block or rack n¹.
By loosening said screw the collar 650 may be turned and removed, and the friction
roll may then be easily removed.
The rack-teeth n² of the block are engaged by a toothed sector n³ secured to a
short shaft n having its bearings in a block provided for it, and to said short shaft a
crank-arm n is secured which extends rearwardly and which is connected to the
pivoted arm f¹ by a spring n' and also by a pin n², the latter being connected at both

page_text: ends by ball and socket joints, or other loose connections. It will be observed that
whenever the arm f¹ is depressed the crank arm n³ will be correspondingly moved,
thereby rocking the shaft n4 and raising the channel knife holder.
The machine thus shown and described may be used as a universal rounding or
rounding and channelling machine, that is to say, it may be operated to trim a plain
edge, or an extension edge of either the Scotch or Baltimore variety herein referred to.
Two guides a and f are shown but in many instances we may use only the guide a
either with or without all of its operating devices.
