Improvements in Heel-breasting Machines for use in the Manufacture
of Boots and Shoes.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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:-
This invention has relation to machines for trimming or cutting away the
heels of boots and shoes, but has relation more particularly to machines for
breasting or cutting away the breasts of the heels, and it consists of a machine
possessing certain features of construction and relative arrangement of parts,
all as illustrated upon the drawings, and now to be described in detail, and
finally pointed out with particularity in the claims.

page_text: Fig. 18 represents a side elevation of the machine from the opposite side from

Figs. 20 and 21 are sections on the lines 20-20 and 21-21 of Fig. 19.
Referring to the drawings, which show one form of machine, preferably
sélected for the purpose of illustrating the invention, indicates a base-plate
which may be supported by logs or standards a¹. Bearings brackets arise
from one end of the plate or bed, and shafts 66 are journaled therein, the
former being the driving shaft to which power is initially applied, and the
latter being the shaft which imparts movement to the knife and which is
driven at a relatively low rate of speed. Upon the shaft is loosely secured
a belt-wheel b*, there being suitable clutching devices between the wheel and
the shaft to connect the two together whenever desired. A pinion on the
shaft b intermeshes with and drives a large gear-wheel on the shaft 6', there
being on the last-mentioned shaft an eccentric and connected to the strap c¹
is an eccentric rod by means of which the knife is reciprocated, as will be
hereinafter described.
Upon the standard d, rising from the central part of the bed a is a horizontal
table or plated having under-cut flanges, as shown in Fig. 6, to receive
a dove-tailed carrier or slide e.
This carrier or slide is provided with a socket 3, as shown in Fig. 16, to
receive the shank. of the knife f. A screw is threaded into the end of the
shank and bears against the rear wall of the socket so that by turning this
screw, the knife may be adjusted in and out of the socket. After being once
adjusted to the proper point, the knife is held against movement by a screw el
passed through an arch e of the slide and bearing against a wearing block c
placed upon the top of the knife.
The rear end of the slide is bifurcated to receive a link g hinged theroto
by a pintle extending through the slide as illustrated in Fig. 16, and the
link g is in turn bifurcated and connected to the eccentric rod by a pintle g³.
Thus far, it will be seen that for each reciprocation of the eccentric-rod, the
slide and knife will be likewise reciprocated.
Secured to one side of the table d' is a grooved strip or plate slotted as
at h¹, to receive the screws which hold it in place, but which permit it to
slide back and forth relatively to the table. On its rear end, the plate or strip
is formed with an upwardly projecting portion having a curved groove *
slightly offset at h (see Figs. 12 and 13). The groove is on the inner side of
the plate and it receives a trundle or roll on the end of the pintle which,
as stated, connects the eccentric rod with the link g. A spring ¿ connects
a pin he, projecting down from the plate h, with a pin projecting out from
the bracket d, so that the trundle normally remains in the offset h in the
sloth. When the eccentric rod is projected, the eccentric rod and the link
are in alinement, or at a dead center, and they force the knife slide and the
strip forward until the strip h is prevented from moving further, or meets
with a serious resistance, whereupon the continued movement of the eccentric
rod causes the trundle to engage the wall of the slot hat he and roll up the
curved sloth and complete its full stroke, even though the knife-slide and the
strip remain stationary.
The parts and a constitute a toggle for operating the knife-carrier posi-
tively or unvieldingly, and said toggle is broken by the bunter at the moment
the knife has completed its work upon the heel.
Upon the strip is mounted a finger shaped as shown in Figs. 1. and 11,
and having its free end very slightly in advance of the edge of the knife. The
other end of the finger is pivoted at to the end of the strip h and the free end
may be adjusted relatively to the knife-edge by a screw, passed through
a bracket secured to the side of the strip h, the end of said screw bearing

page_text: a
against the finger, as shown in Fig. 17. The finger and the strip h constitute
bunter," or mechanism for stopping the travel of the knife when it has cut
through the leather of the heel to a proper extent, and while the power devices
complete their full throw, and they likewise perform the function of destroying
the operative relation existing between the ecentric rod and the knife carrier.
The support for the sole of the shoe consists of a plate k pivoted at /¹ to an
arm extending up from the bed or plate a, and in order to hold the sup-
porting plate at any angle relative to the bed, it is provided with a down-
wardly projecting web to which is pivoted a link, the end of which is
slotted and serrated, as shown in Figs and 2. A screw is passed through
the slot into the bed-plate and its head presses a serrated washer against
the end of the link so as to hold it against movement. By loosening the screw k",
the shoe supporting plate may be adjusted about the pivot or fulcrum A¹ to
the angle desired.
The upper converging end of the plate is flanged as at to provide a
support for the base of a gage 18 for the toe of the shoe, by means of which
the shoe may be properly positioned upon the plate.
Pivoted upon the front face of the plate are two positioning fingers or levers
having their lower enda shouldered and outwardly spreading as at 7. They
are provided with inwardly projecting portions having teeth upon their ends
which intermesh, whereby when one of the arms is swung about its center of
motion, the other arm is likewise moved and to the same extent. One of the
arms swings loosely about its pivot stud while the other arm is rigidly
secured to its stud so that in case the latter be partially rotated or rocked,
the two arms will be both swung about their centers.
The studs, pass through slots in the plate and are set into a cross-
bar m which has à rib m² lying in a slot 10 in the plate k and movable longi-
tudinally of the said plate.
Upon the upper ends of the arms are journaled rollers, Iving in a curved
slot in a guide a likewise formed with a rib to project into the slot 10 from
the front, shown in Fig. 3. An adjusting screw n is threaded into the guide
and has its lower non-threaded part supported in a stud projecting forward
from the plate and bridging the slot io, as illustrated in Figs. 3 and 4.
By rotating the screw n², the guide strip, together with the positioning
arms 1, and the cross-bar m, may be all adjusted longitudinally of the plate
to change the position of the arms 1, 1, for shoes of different sizes or having
heels of different sizes.
Usually, after the heel has been placed upon a shoe in the process of manu-
facture, a top-lift is spanked in place, the top-lift being usually smaller than
the heel, the dimensions of which are subsequently reduced by proper tools to
correspond with those of the top-lift. Consequently. when it is desired to breast
the heel, the shoe is positioned with relation to the top-lift and not to the
remainder of the heel. Hence the shoe is placed against the supporting plate
with the corners of the heel fitting. in the notches in the ends of the arms 7 and
the toe of the shoe is held against the gage so that the median lines of the
shoe are parallel with the said gage, after which the knife is advanced to cut
the heel.
The shoe is jacked against the plate by the following devices:
The bed-plate is extended at of to receive a bracket a on the bifurcated
end of which is journaled a shaft o. The bracket is secured in place by a
screws passed through an enlarged aperture in the bed, and the bed and bracket
are both serrated so that the latter can be adjusted towards and from the shoe
support. A hand-wheel o¹ is placed upon the end. of the shaft and between
the bifurcated arms of the bracket a is placed a spiral cam o³ having its cam
rib extending between a pin secured to a sliding bar and a roller o as
shown in Fig. 3. this roller lying in a socket in the end of the slide-bar os. To
the opposite end of the slide-bar is pivoted a foot-piece 08 to bear against the

page_text: top of the last and press the shoe against the supporting plate k. Thus it will
be seen that by turning the hand-wheel ¹, the slide-bar o may be forced
forward or retracted, as desired, to clamp the shoe against the supporting plate
or else release it therefrom.
When the shoe has been jacked in place by the jacking device just described,
the knife is advanced, but inasmuch as the positioning arms are then in the
way of the knife, we provide means for swinging them out of its path as it
advances. These means consist of a bent arm p secured rigidly to the pivot
stud and a cam lever 21, pivoted at p to the table. Upon the knife slide
is mounted a roller p³ which as the slide advances, engages the bent portion
of the lever p¹ and swings its forward end outward. The bent arm phears
against a screw passed through the forward end of the arm p', so that as
the forward end of the latter is thrust outwardly, the arm is swung about
its center of motion to rock the stud , and cause the lower ends of the arms 17
to swing apart. The arms are connected by a spring which normally
holds their lower ends together but they are held apart by a screw 9, passed
through the arm p, and bearing against the edge of the plate k and by rotating
the screw, their ends may be adjusted towards and from cach other."
The operation of the machine is as follows:
The shoe is placed against the plate with the corners of the top-lift fitting
in the notches in the arms and with the toe properly positioned with respect
to the gage 8.
Then the hand-wheel o' is rotated to advance the slide-har o to jack the shoe
in place. Then by a suitable treadle mechanism, not shown, the clutch devices
are thrown into operation to connect the belt-wheel with the shaft b. Imme-
diately thereupon, through the medium of the gearing previously described, a
rotution is imparted to the shaft 6', and as the shaft begins to rotate, the eccentric
rod is projected, forcing forward the knife-slide which, as it advances, causes
the positioning arms to separate and move out of the path of the knife. At
this time, the link and the eccentric rod are in alinement, and the knife con-
tinues its travel, (the finger and knife f passing through an aperture in
plate k,) until the finger strikes against the insole and stops the travel of the
sliding strip h, whereupon the roll g³ engages the curved wall 48 of the slot h*
and travels up the slot + while the knife and its carrier remain stationary.
Then the knife-slide or carrier is withdrawn and when the shaft bb¹ has com-
pleted one revolution, by devices not shown, the clutch devices are thrown out
of engagement with the shaft and wheel and the shaft b¹ is stopped.
We may employ any desired stopping device such as a brake-shoe r to engage
a friction disk on the shaft 61, the brake-shoe being connected to the sliding
sleeve which actuates the finger through the medium of which the clutch
devices are actuated to engage the belt-wheel & with the shaft b.
Where broad-toed shoes are being breasted, we may employ a gage k³, as
shown in Figures 8 and 9, which may be placed upon the gage and secured
at any desired height thereon. The device shown is provided with two fingers k
by means of which the position of the so-called corners of the toc may be
accurately determined by with respect to such fingers. The said gage ¹ is not
adapted to engage with the toe of the shoe but merely serves to determine the
correct central position of the said toe. The shoe will therefore be placed in
proper relation to the breasting knife. The sole of the shoe should be upright
during the breasting operation, and the operator is enabled by the fingers
locating the shoe in proper position with relation to the fingers, to thereby
locate the heel in proper position with respect to the knife.
It will be observed that the edge of the knife when viewed from the end, is
curved in the arc of a circle, see Fig. 15 & 16, and consequently, it is desired
that the ends of the arms should move through the same arc so that the shoulders
on the ends of the arms may always remain in alinement with the knife edge.
By reason of pivoting the arms 7 they naturally move in different paths, and
=

page_text: consequently the upper ends of the arms are provided with rollers extending
into the curved slot in the cross guide n. This is either straight or so curved
that when the arms are swung outwardly to accommodate a heel of any size,
the arms not only swing about their pivot studs, but are also raised bodily
whereby they swing in an arc or in a straight line parallel with the edge of the
knife which may be either curved or straight. This is an important feature
of the invention, because if the ends of the arms do not swing in an arc parallel
to the arc of the knife, a large heel would be presented to the knife in such
way that more of it would be cut away than would be desirable, while a small
portion of a smaller heel would be removed, leaving the heels relatively
unfinished.
Another important feature of the invention is the mechanism by means of
which the knife is positively driven to cut away the heel and is automatically
stopped before it has an opportunity to cut the sole, this mechanism operating
perfectly with heels of different thicknesses.
Heretofore breasting machines have been of either of two kinds; that is to
say, the knife was positively driven a predetermined distance each stroke, and
it was necessary to adjust the shoe-holder for each height of heel in order that
the knife should cut therefrom the proper amount of stock, or else the knife
was connected with its driver by yielding means, as a spring, and a hunter was
positively or rigidly connected to the knife to strike against the sole and arrest
the motion of the knife after it had penetrated the heel to the desired extent.
The present machine, however, is provided with means for positively, ¿.e., unyield-
ingly driving the knife, and also with mechanism for automatically arresting
the motion of the knife when it has completed its cut through the heel and
before it has a chance to cut the sole. And in this connection we desire to state
that whenever we use the word "positively" in connection with the driving
mechanism, it will be understood that we mean thereby that the knife is driven
unyieldingly.
As will be readily apparent to those skilled in the art to which this invention
appertains, various changes in the construction and arrangement of the parts
of the hereinabove-described machine may be made without departing from the
spirit and scope of the invention, and that the several features or parts may
be utilized separately or in connection with machines of other constructions.
For instance in Figs. 19, 20 and 21, I have illustrated the rear end of a
machine in which the throw or movement of the knife carrier is always the
same, and the shoe is adjusted towards or from the knife. In this embodiment
of the invention, the knife carriers is constructed substantially as hereinbefore
described, but it is connected by a pivot to the reciprocating rod s', so that its
movements are always of the same length or degree. A carriage is slidably
mounted on the base-plate of the machine and is provided with a rigid block
depending into a longitudinal slot, from which block a pin projects down-
wardly, and pivotally supports a block (shown in dotted lines in Fig. 20).
An arm u is pivoted upon a stud under the base-plate, and is provided with
an eccentric slot u into which the block extends, so that if the arm be swung
to one side or the other, the carriage will be moved towards or from the knife
carrier. To accomplish this movement of the arm w, it is connected by a link w
with an arm ³ frictionally engaging a shaft ut, journaled in the end standards
of the machine, and another arm us rigidly secured to said shaft having its outer
end connected by a link with a treadle (not shown) by means of which the
belt-wheel is clutched to the main driving shaft of the machine. A spring
(likewise not shown) normally holds the arm in the position illustrated in
Fig. 20, so that the carriage is withdrawn.
13
Upon the carriage is mounted the sliding har 06, the cam ³, and the hand-
wheel o, the latter not being shown, and also the gage-plate, support or
abutment for engaging the face of the heel, and holding the heel in any
desired plane relatively to the knife. The plate is provided with a pintle &¹ in

page_text: a lng extending upward from the carriage; and it has a downwardly pro-
jecting finger 1, to which is pivoted a connecting rod having in its free end
a slot through which a bolt 6 passes into the carriage to adjustably secure
it. By loosening the bolt the gage plate may be adjusted to any desired
position substantially as herein before set forth.
In order to prevent the knife from cutting the sole, when the shoe is jacked
against the plate in the carriage, and the carriage is moved towards the knife,
we employ a guard or bunter, which acts as a stop to limit the movement of tho
shoe towards the reciprocating knife. This bunter consists of an arched rod w,
spanning the carriage and pivoted in brackets secured upon the base plate
on either side of the carriage. This rod has a finger through which an
adjusting screw 10 passes and bears against the base-plate, whereby the said
bunter may be adjusted in lines substantially parallel with the lines of movement
of the knife.
!
In this embodiment of the invention, the shoe is jacked in the carriage, and
the latter is moved forward until the sole rests against the bunter. This is
accomplished by the first movement of the treadle, when it is depressed, the arm
heing frictionally mounted upon the shaft u to permit a further rotation of the
shaft caused by the further depression of the treadle to start the machine.
The bunter is automatically adjusted for the various heights of heels to be
breasted, and in this way, the cutting of the sole is prevented.
