Improvements in Sole-levelling Machines for 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 relates to machines designed for acting upon the soles of boots
and shoes for leveling the same without the exercise of care and skill on the part of
the workman otherwise than preparing the boots or shoes, mounting and dismounting
the same, actuating the treadle, and manipulating the devices necessary to start
and stop the machinery and adjust the working parts as occasion demands, or the
conditions require, or the particular work in hand may render necessary.
The chief object of my invention is to provide a new and improved sole-leveling
machine which is susceptible of leveling the soles of boots or shoes which differ or
vary in size from the minimum to the maximum.
To accomplish this object my invention involves the features of construction,
the combination or arrangement of parts, and the principles of operation hereinafter
described and claimed, reference being made to the accompanying drawings, in

In order to enable those skilled in the art to make and use my invention, I will
now describe the same in detail, referring to the drawings, wherein the letter A
indicates the main driving, or power shaft, having fast and loose pulleys, or other
means whereby it may be rotated at will by power derived from any suitable motor.
This driving-shaft is journaled in bearings a on the lower part of a main frame B
of any construction suitable for supporting the various working parts which
constitute our organized sole-leveling machine, and the shaft is provided with a
bevel-gear a', keyed or otherwise attached thereto and meshing into a bevel-gear 'c
fixed on a vertical shaft C which is arranged to rotate in upper and lower bearings c
of the main frame. The shaft C is also provided with a worm designed to
engage a worm-gear d, best seen in Fig. 2, which is secured to and drives a
transverse countershaft D, arranged to rotate in bearings d' on the rear end of the
main frame, and provided at one end with an attached carrier or sleeve d³,
Figs. 9 and 10, keyed or otherwise connected therewith. The circular head of
the carrier or sleeve d' is chambered or recessed to receive a rectangular, or other
suitable projection de, formed or otherwise provided upon the rear of a rectangular
slide d³, having a crank or wrist-pin d, and susceptible of moving between suitable
ways d, attached to, or forming a part of the chambered or recessed head of the
carrier or sleeve. The head of the carrier or sleeve is provided with a screw d',
arranged approximately at right angles to the transverse shaft D, and adapted to
loosely turn in either direction in the head of the carrier or sleeve, but prevented
from moving in the direction of its length through the medium of the end collar d³
and nut do. The screw d' is provided on one end, at a point outside the chambered
head of the carrier or sleeve, with a conical friction roll or wheel do, preferably
made of superimposed layers, but which may be of any construction suitable for
the purpose. The screw is in screw-threaded engagement with the rectangular
projection d of the slide, and obviously by turning the screw in one direction, the
slide will be shifted towards the center of the countershaft, and the throw of the
crank-pin d carried by the slide will be decreased, and, conversely, if the screw be
turned in the opposite direction, the slide will be moved in a direction away from
the center of the countershaft and the throw of the crank-pin will be increased.
The sleeve or carrier and conical friction roll or wheel are housed within or
surrounded by a cylindrical, or other suitably shaped casing d", having a hub
portion encircling the sleeve or carrier, and provided upon its interior with two
opposite conical or inclined surfaces d¹ and dis, either of which is adapted to bear
against the surface of the friction roll or wheel do when the casing d is moved in
one or the other direction upon the carrier or sleeve. The casing d" is moved
laterally through the medium of a rocker-arm e pivotally connected with the hub
of the casing d through the medium of pointed screws e, and secured to a rocker-
shaft E, mounted in bearings e2, Fig. 1, of the main frame. The pointed screws e¹,
connecting the rocker-arm with the hub of the casing d prevent the latter from
rotating with the carrier or sleeve d, while enabling the casing to be shifted
laterally thereupon.
The rocker-shaft E is oscillated or rocked through the medium of the hand-
23

page_text: lever e³, Figs. 1 and 2, which is rigidly secured at its lower end to the rocker-shaft
and is provided at its upper end with a suitable handle. The hand-lever e³, at the
left-hand side of the machine, is connected by a transverse rod e', with a hand-
lever e located at the right-hand side of the machine, in such manner that the
rocker-shaft E can be oscillated or rocked from either side of the machine. It will
be obvious, therefore, that by operating either one of the hand-levers the rocker-
arm e will be caused to rock and thereby shift the cylindrical casing dll in one or
the other direction, and cause either of the inclined or conical surfaces d¹ and d¹³ to
come in contact with the periphery or surface of the conical friction roll or wheel d¹º.
Inasmuch as the driven countershaft D imparts rotary motion to the carrier or
sleeve d³, the conical friction roll or wheel is caused to rotate therewith and travel
against either of the conical or inclined surfaces d" and d. If the rocker-arm e
be caused to move to the right, Fig. 10, the surface d¹³ will be pressed against the
conical friction roll do, and as this roll is revolved around shaft D in the direction
of the arrow 1, Fig. 9, while the surface d is stationary, the friction roll do is
caused to rotate, and thereby turns the screw d in the direction indicated by the
arrow 2, Fig. 10, causing the slide d³ to move in a direction towards the axis of
the countershaft. By moving the rocker-arin e to the left, Fig. 10, the conical
surface d is forced against the friction-roll do and the rotation of the screw is
reversed, thereby moving the slide d³ and crank or wrist-pin in a direction away
from the center of the shaft D.
The front end of the rocker-shaft E is provided with an attached plate e, best
seen in Fig. 8, having a depression or recess e adapted to receive the pointed
outer extremity of a pin e, which is urged in an outward direction through the
medium of a spring e. The pointed extremity of the spring-pressed-pin lies in
the depression or recess when the cylindrical casing d is in its central position, as
shown in Fig. 10; that is to say, when it is in a position with both of its conical or
inclined surfaces out of contact with the friction-roll, so that the screw will not be
rotated, and consequently the slide will stand in the position to which it has been
previously adjusted by the rotation of the screw.
The main frame of the machine is provided at its front portion with a transverse
jack-shaft f, to which is firmly secured, in any suitable manner, the jack F. The
jack is susceptible of oscillating or reciprocating longitudinally, which is accom-
plished by rocking the jack-shaft. This shaft is provided at the left-hand end
with a crank-arm, connected by a link f with the crank-pin d on the slide d³.
The rotary notion of the countershaft D causes the carrier or sleeve d³ and
crank pin d² to rotate, and thereby transmit an oscillating motion to the crank-arm f
and the jack-shaft.
The main frame of the jack comprises a yoke-frame f³, which is rigidly attached
to the jack-shaft, a laterally rocking yoke f, and a laterally movable frame ƒ³
mounted on the rocking yoke and having two angularly arranged shoe-supporting
arms fand f1.
The jack, therefore, is of the type known as a duplex or double jack, and is
provided with suitable holding devices for receiving two boots or shoes, so that
while one part of the jack carrying a boot or shoe is in a position to be operated
upon by the leveling rolls, another part for receiving the other shoe is in a position
to enable the boot or shoe to be placed thereupon in readiness to be moved into
position under, and operated upon by, the leveling rolls at the proper time, as will
be understood by reference to Fig. 11, wherein one of the shoe-supporting arms,.
as f, is represented as in position for the leveling rolls to act upon the sole of such
boot or shoe, while the other shoe-supporting arm, as f", is swung laterally into
position to receive the prepared boot or shoe which is to be subsequently operated
on by the leveling rolls.
The arms of the yoke fare pivoted at their upper ends to the arms of the
yoke-frame f, through the medium of a fixed pivot-stud f and a movable pivot f'.
fixed to one of the arms of the yoke f and adapted to turn in one of the arms of.
the yoke-frame f³. The pivot-stud f* is secured to one of the arms of the yoke f*

page_text: through the medium of a screw, and one of the arms of the yoke f is adapted to
turn on this pivot-stud, while the pivot-stud f' can turn, all in such manner that
while the yoke-frame oscillates or reciprocates longitudinally, as hereinbefore
explained, the yoke f* is susceptible of moving or swinging laterally, although it
may be locked stationary, as will hereinafter appear. The pivot f', which, as
before stated, is adapted to turn in one of the arms of the yoke f, and is rigidly
secured to one of the arms of yoke f4, is provided with an attached pendent arm or
lever f having at its lower extremity a clamp-screw f', and a hand-nut 10. The
clamp-screw extends from the arm or lever through a curve or segmental
slot 2, Fig. 8, provided in or on a bracket f27, which is rigidly secured to the
front end portion of the yoke-frame f³. The arm or lever f³ is used for the
purpose of manually rocking the yoke f laterally, or sidewise, whenever desired
during the action of the leveling-rolls on the soles of the boot or shoe, but the
construction of parts is such that the hand-nut f10 can be tightened upon the
clamp-screw for the purpose of rigidly locking the yoke in any desired
position to the frame f. It will be obvious that the yoke f can be rigidly locked
while it stands in a perpendicular plane, or it can be locked at any desired angle
of inclination, as will be readily understood by reference to Fig. 8.
The laterally movable frame f, carrying the horizontally arranged arms f
and 13, extends from a vertical sleeve f13, Figs. 1 and 3, in such manner that when
one of the arms supporting a shoe is in proper position under the leveling-rolls J
and 1, the other arm extends laterally and rearward, as will be clearly understood
by reference to Fig. 11, so that it is in convenient position to receive a boot or shoe,
the sole of which is to be subsequently leveled. The two horizontally arranged
arms are adapted to swing in a horizontal plane to place one arm in proper position
under the leveling-rolls, and the other out of position to receive a prepared boot or
shoe. To accomplish this lateral swinging motion of the shoe-supporting arms, the
sleeve 13 is constructed at its upper and lower ends with ball bearings formed, as
here shown, by constructing the upper and lower ends of the sleeve with convex or
rounded ends f14, best seen in Fig. 64, which seat in upper and lower concave sents
formed in suitable supports f1 and fie. A vertical, cylindrical pin or post f
extends through these supports and the sleeve, and tightly fits the supports while
it loosely fits the sleeve, so that the sleeve is free to turn without necessarily
turning the pin or post. The bore or passage through the sleeve f13 is of a
diameter greater than the diameter of the pin or post f17, so that it is possible for
the sleeve to tilt back and forth.
The arms f and f12 are each provided with a locking bolt or pin f20, Fig. 6,
adapted to engage a locking recess or depression f1, formed in a plate 18, Fig. 12,
secured to the rear end portion of the rocking yoke 4, the construction being such
that when the arm f", for example, is in position to properly support a shoe under
the leveling-rolls, its bolt or pin f20 will lie over the recess or depression 10, and,
owing to the weight of the arm, the bolt or pin will engage the recess or depression.
The downward pressure of the leveling-rolls on the sole of the shoe serves to hold
the bolt or pin in engagement with the recess or depression. When the leveling-
rolls are raised from the sole of the hoot or shoe, as will hereinafter appear, the
horizontally arranged arm f is slightly raised at its rear end by the operator, for
the purpose of disengaging the bolt or pin from the recess or depression fin
the plate f, after which the arm fi can be swung laterally out of operative
position, and the arm f into operative position in the yoke f, whereupon the bolt
or pin f20 of the arm 12 will be engaged with the locking recess or depression 19
of the plate 18 by the weight of the arm and is held or locked in position by
downward pressure of the leveling-rolls in the same manner as before explained
with reference to the arm f".
As before stated, the bore of the sleeve f18 is of a diameter greater than the
diameter of the pin or post f", and consequently the sleeve can tilt back and forth
to slightly raise and lower the arm f", and thus cause the bolt or pin f20 to engage
and disengage the recess or depression. The extent to which the sleeve, and

page_text: consequently the arms f" and f" can tilt is regulated by the comparative size of
the bore in the sleeve with relation to the size of the pin or post f".
The arm f is provided with a stop-lug f", Figs. 1, 3, and 14, constructed to
engage a stop-lug or shoulder f, provided on the yoke f, so that when the arm is.
swung into operative position to engage the yoke, the stop-lug f" will rest against
the stop-lug or shoulder f, thereby centering the arm and insuring the proper
engagement of the locking-bolt or pin f with the locking recess or depression, f
The arm is provided with a lug f, Fig. 6, adapted to bear against a lug 24
on the yoke f, in substantially the same manner as described with reference to the-
armf, for the purpose of centering the arm f1 in the yoke.
The horizontal arms and fare each provided with a toe-post G and
a heel-post H, best seen in Fig. 6, which are adjustable longitudinally in a direction-
towards and from each other, for the purpose of enabling shoes of different sizes to
be mounted on the shoe supporting arms and to be properly sustained while the
soles are being leveled. The longitudinal adjustment of the toe and heel posts of
each arm for ", is accomplished through the medium of a longitudinal rack f25
rigidly secured to, or formed with each arm, and into which mesh pinions g and h,
having shafts suitably mounted, respectively, ou parts of the toe and heel-posts, and
provided with hand-wheels y' and ', which can be readily manipulated for rotating
the pinions and causing them to traverse the rack of each arm. The pinions can-
be independently rotated, so that the toe and heel posts are independently
adjustable longitudinally, or in a direction along the length of the arm on which
the parts are mounted. The heel and toe posts can be rigidly held in the position
to which adjusted by locking the pinions against rotation, and while this can be
accomplished in any suitable manner, I prefer to effect the locking operation
through the medium of lock-nuts 92 and h2, Fig. 11, which can be operated to-
rigidly clamp and hold the hand-wheels g' and against rotation, and since the
pinions g and are rigid on the shaft or spindles to which the hand-wheels are
secured, it will be obvious that the pinions will be locked in engagement with the-
rack, and thereby prevent movements of the toe and heel rests.
The toe-post comprises a toe-rest 96, a toe-guard g', a screw-shank g³ having a
head, and a tubular post in which the screw-shank is arranged and on which the
shaft of the pinion g is mounted.
Inasmuch as all the parts of the toe and heel posts of the arms f" and f" are
alike, a description of one is sufficient for both.
The screw-threaded shank g of the toe-post is vertically adjustable in the-
tubular post throngh the medium of the nut g' mounted on the upper end of the
post and in screw-threaded engagement with the shank. The shank is prevented
from rotating by means of a screw 9 inserted laterally through the tubular post
and bearing against an unthreaded part of the shank. The screw preferably enters
the slot in the shank, so that rotation of the latter is effectually prevented unless-
the screw be disengaged from the slot.
The toe-rest g and toe-guard 97 are pivoted to the head of the screw-shank g³,
through the medium of suitable pins or pivots, as at g and g". The rear end
portion of the toe-guard is the pivoted part, so that its rear front portion can be
raised or lowered with relation to the toe portion of the sole of the shoe mounted
on the last I, which is carried by the heel-post. The vertical adjustment of the
front end of the toe-guard is effected by means of a set-screw 1, tapped into the
head of the screw-shank g. The toe-guard g' is composed of a curved plate, upon
which the fore-part leveling-rolls J pass and rest when they run off the toe portion
of the sole of a boot or shoe.
The adjusting screw g" is adapted to be held against rotation after the desired
adjustment of the toc-guard is effected by means of a screw g13, or in any other
suitable manner. The front end of the toe-rest g can be raised or lowered by a
set-screw 9, tapped into the head of the screw-shank g³. This screw g can also
be locked in position after the desired adjustment is effected by means of a
screw go, or by any other suitable means: The toe-rest ge can be adjusted to-

page_text: accommodate varying shapes of boots or shoes, while the toe-guard g' can be
accurately and nicely adjusted approximately flush with the tread of the boot or
shoe sole when the latter is mounted and in position to be acted upon by the
leveling-rolls J and . The toe-guard receives and supports the fore-part roll J
when it leaves the extreme point of the toe-portion of the sole, and thus prevents
the toe end of the sole from being mashed down, or otherwise damaged or injured;
and, likewise, when the fore-part roll passes from the toe-guard onto the toe
portion of the sole, the latter will not he pounded and danaged or injured,
because the upper surface of the toe-guard is approximately flush with the tread of
the sole.
The
The heel-post H comprises a tubular post h³, at the base of which the shaft which
carries the hand-wheel and pinion is mounted. The tubular post h³ contains a
cylindrical heel-guard carrier which is journaled in the post 43, so that it can be
axially rotated. The post is provided with a spring-pressed locking-pin,
adapted to engage a locking recess in the cylindrical carrier h, for holding the
latter in a central position, as shown in Fig. 6. The cylindrical carrier contains a
screw-shank, engaging a screw-nut 7 mounted on the upper end of the carrier,
so that it is possible to raise and lower the screw-shank by rotating the nut.
screw-shank is prevented from rotating in the carrier through the medium of a
screw 8, which passes through the base portion of the carrier and engages the
unthreaded lower end of the screw-stud. The screw preferably engages a slot in
the unthreaded part of the screw-shank, so that the latter is effectually held against
rotary motion in the carrier. The upper end of the screw-shank is provided with
a head which carries a pin adapted to enter a pin-hole in the last I, as is usual in
this class of machines. The cylindrical heel-guard carrier is provided with a
horizontally projecting socket in which a standard 5 is vertically adjustable
through the medium of a clamping screw h¹, which can be loosened to raise or
lower the standard, and then tightened to clamp it in its adjusted position. The
upper end of the standard is provided with a horizontally movable slide 2, Figs. 6
and 5, which is bifurcated to embrace the heel portion of the shoe. The slide is
preferably dovetailed to the upper end of the standard, and to the rear extremities
of the arms of the bifurcated slide are pivoted, by pivot-pins 1, the arms of a heel-
guard 10 which is susceptible of being raised and lowered to suit the conditions
required, through the medium of a vertically adjustable set-screw 13, mounted in a
part of the slide. This set-screw is adapted to be rigidly locked after adjustment
through the medium of a clamping screw 4, engaging a split part of the slide h
which split part embraces the dove-tailed guide or way provided on the upper end
of the standard 1 for the longitudinal adjustment of the slide. The clamping
screw not only clamps the set-screw on which the heel-guard rests, but also clamps
the split part of the slide upon the dove-tailed guide or way.
The devices described render the heel-guard susceptible of being bodily raised
and lowered by raising and lowering the standard h; also of being adjusted to
different angles of inclination by vertically adjusting the set-screw 13, and of being
adjusted horizontally by shifting the slide 2 on the head of the standard, whereby
the heel-guard is rendered practically operative under all possible conditions and
in connection with shoes of different sizes and shapes. The broad body portion of
the heel-guard 10 serves to protect the portion of the shoe, where the heel is
attached, from being damaged by the shank-roll ". The heel-guard also serves to
receive and support the shank-roll where spring heel shoes are being leveled; that
is to say, in operating on this class of shoes the shank-roll passes over the heel and
onto the heel-guard. In shoes which are to have heels attached, the shank-roll
should not pass over the breast of the heel, and the heel-guard should be adjusted
so that the shank-roll will roll onto the heel-guard after passing the shank as far as
the breast of the heel. The mechanism controlling or governing the shank-roll
controls or governs the distance of travel of this roll on the shank, but the improved
heel-guard will enable the operator to exercise his own judgment as to changing
the travel of the roll or setting the heel-guard so that the roll may pass or travel

page_text: the same distance and yet not operate directly on the sole more than is necessary t
secure the best results. In spring heel work the heel-guard performs the same
work for the shank-roll as the toe-guard does for the fore-part roll; that is to say,
the guard acts as a rest for the roll after the latter passes over the shank and beel
portion of the sole.
The shank-roll is preferably composed of two sections having properly concave.l
or grooved peripheries, and is journaled on a shaft", secured in arms or
supports extending from a yoke-shaped oscillatory frame or support and
connected to the arms thereof by clamp-screws so that it is possible to
adjust the shank-rolls vertically with relation to the jack by loosening the clamp-
screws, raising or lowering the arms or supports, and then tightening the clamp-
screws.
The yoke-shaped frame or support is vertically adjustable and is adapte.l to
rock or oscillate laterally, and to accomplish this it is centrally journaled on a
stud, projecting from a vertically movable slide, mounted in suitable ways at
the center of a longitudinally movable yoke-shaped carrier-frame ". The vertically
movable slide 2 can be raised and lowered in the ways at the center of the carrier-
frame, by means of a set-screw, thereby raising or lowering the shank-roll to
suit the conditions required.
The yoke-frame is locked in its central position to the slide , as shown in
Fig. 5, by means of a spring-pin, which can be withdrawn from engagement
with the slide by a suitable handle, thereby leaving the yoke-frame and the
shank-roll free to oscillate or rock from one side to the other of the shoe-sole, for the
purpose of properly conforming to the varying curves of the shank portions of
the soles and to accommodate itself to whatever conditions may be required.
It will be seen from the foregoing description that the yoke-frame or carrier 2,
which directly supports the shank-roll, can. be locked in a fixed central position, or
it can be permitted to freely oscillate or rack laterally as may be desired in
operating upon the soles of boots or shoes differing in shape or size.
The rear extremity of the carrier-frame rests against and is movable upon the
upper side of a horizontal pin 13, mounted in the vertical arm of a bell-crank-
lever, which is pivoted by a pivot-pin carried by the upper end of a rocker
arm 8, Figs. 3 and 7, which is fixed to a rocker-shaft 7, mounted in suitable
bearings on the main frame B, all in such manner that when the rocker-shaft 7 is
rocked, the rocker arm is rocked, the bell-crank-lever is bodily shifted back
and forth, and a longitudinally reciprocating motion is imparted to the carrier-
frame, and to the parts carried thereby, thereby causing the shank-roll to
move in the same direction that the jack is moving, the extent of movement, or
longitudinal travel of the shank-roll being governed by the extent of movement of
the jack.
through the*
is
The rocker-shaft is rocked by connections with the jack-shaft
medium of the following connections, to wit: a rocker-arin i, keyed, or otherwise
secured to the rocker-shaft 7, and connected by a link with a rocker-arm I'
secured to the jack-shaft f. The rocker-arm on the jack-shaft is provided with a
longitudinal slot 3, in which a slide-nut is adapted to move. The nut
pivotally connected with the link by a pin , and the nut is in screw-threaded
engagement with a rotatable screw i, having at its upper end a suitable hand-
wheel, so that by rotating the screw in one or the other direction, the nut is
raised or lowered, and the stroke of the rocker-arm ", and consequently the extent
of motion of the rocker-arm, and the parta connected therewith, can be regulated
or varied at will, thereby enabling the extent of travel of the shank-roll to be
changed, as may be required, according to the size of the boot or shoe which is to
be operated upon.
The horizontally arranged arm of the bell-crank-lever is connected by a
connecting-rod with an eccentric i, mounted on the main driving-shaft A, as
best seen in Fig. 3, whereby the bell-crank-lever is oscillated, or vibrated
independently of the back-and-forth motion produced by the rocking movements

page_text: ⋅
of the rocker-arm 28. In other words the rocking movements of the rocker-arm 28
impart a longitudinally traversing motion to the carrier-frame and the shank-
roll, while at the same time this carrier-frame and the shank-roll are vibrated
longitudinally by the movements of the bell-crank-lever 10. The extent of
longitudinal motion of the carrier-frame " and shank-roll 2 is regulated, as before
stated, by the adjustment of the nut and screw i, so that it is possible to cause
the shank-roll to pass up onto the toe of the sole, or back on the heel portion
thereof a greater or less distance, according to the adjustment of the connections
which operate the rocker-arm. It will be obvious, therefore, that the travel of
the shank-roll, relatively, to the heel, or the fore-part of the sole, can be changed
to suit whatever conditions may be required.
The forward end portions of the arms of the bifurcated carrier-frame are
supported by slidable blocks 3, Figs. 1 and 3, which are pivotally connected with
the arms of the carrier-frame and slide upon suitable guides or pins, fixed or
secured in the horizontal side portions of a frame ", which is pivoted at its rear
end, as at 18, to the top portion of the main frame B, in such manner that the
frame can be raised and lowered and will carry with it the shank-roll and its
*supporting devices hereinbefore described.
The slide-blocks, moving on the guides or pins serve to accurately guide
, the carrier-frame in, all, its longitudinal movements on the frame i¹.
The carrier-frame is capable of longitudinal adjustment to vary the relative
position, of the shank-roll and the boot or shoe mounted on the jack through the
medium of a screw-shaft journaled to rotate in suitable bearings at the rear
end portion of the carrier-frame and passing through, and in screw-threaded
engagement with, the pivot-pin 1, Fig. 3, on the upper side of which the rear end
portion of the carrier-frame rests, as before explained. The rotary motion of the
screw-shaft in one or the other direction, in the pivot-pin 3 will shift the carrier-
frame backward or forward. After the screw-shaft 19 has been turned to secure
the desired adjustment of the carrier-frame, the screw-shaft is designed to be
..locked in a fixed position through the medium of a spring-pressed locking-pin or
-bolt 20.
The leveling-roll, which acts upon the fore-part of the shoe sole during,the
time the shank-roll is acting upon the shank and heel portion of the sole, is
reciprocated or vibrated longitudinally through the medium of a vibrating or
reciprocating carrier-frame, Fig. 4, having its ends pivotally connected through
the medium of pivot-pins to the extremities of a yoke-frame, which, at its rear
extremity, is pivoted to the top portion of the main frame B, as at 18, in such
manner that the frame can be raised and lowered, and will carry with it the fore-
part roll. The vibrating carrier-frame j' is provided with a pivot-pin or stud j³, on
which is centrally mounted a laterally rocking-bar or frame 3, having its ends
constructed with segmental guide-ways, in which are adjustable the slide-blocks j',
which carry the axles or shafts j of the, two sections comprising the fore-part
leveling-roll. The top portion of the vibratory carrier-frame is connected by a
rod with the upwardly projecting arm of a, bell-crank-lever, mounted on the
rocker-shaft which carries the rocker-arms 2 and 28. The horizontally or
rearwardly extending arm of the bell-crank-lever connects by a rod j with. an
eccentric on the main driving-shaft, A, Fig. 2, in such manner that the bell-
crank-lever is oscillated by the eccentric, and a vibrating motion is thereby
imparted to the carrier-frame j, for the purpose of vibrating the fore-part
leveling roll.
The bar or frame 2, on which the fore-part roll is directly mounted, is susceptible
of freely rocking laterally, or it can be rigidly locked centrally in the position
shown in Fig. 4, through the medium of a spring pin ", mounted on a part of
the vibrating carrier-frame.j, and adapted to engage and disengage a part of the
laterally rucking-bar or frame. The spring pin referred to is provided with a
hand piece j, by which the spring-pin can be withdrawn from engagement with
the laterally rocking-bar or frame whenever desired.

page_text: The adjustable blocks j, carrying the axles or shafts of the two-part or sectional
fore-part leveling roll, can be adjusted in the curved or segmental ways on the ends
of the bar or frame, for the purpose of adapting the sections of the fore-part roll
to shoe-soles which differ in contour or shape.
As before stated, the frames j and 7, which are in fact the supporting frame,'
respectively, of the fore-part roll, and the shank-roll, are pivotally mounted, as
at 18, at the top portion of the main frame B, and consequently it is possible for
these two frames to bodily rise and fall. These frames are connected, respectively,
with the upper ends of vertically arranged spring-rods I and I, attached at their
lower ends to a main treadle L, pivoted at its rear portion to the main frame and
adapted to rise and fall, as will be understood by reference to Fig. 1, where the
treadle is indicated by dotted lines in its highest position. The treadle-frame is
pivotally connected by a link with the front extremity of a lever 1³, pivoted
intermediate its extremities, as at I, to the main frame of the machine, and having:
its rear extremity provided with a counterbalance weight 1, which, as here shown,:
is spherical, but which may be of any desired form or shape. The counterbalance
weight serves to counterbalance the treadle-frame, and the main frames " and
and all parts which are mounted upon said frames. When the treadle frame Lis
depressed, the connecting rods and serve to draw the supporting frames.
and downward, for the purpose of pressing the leveling-rolls upon the sole of the
boot or shoe which is to be leveled, and when the treadle frame is depressed, asi
above stated, it is designed to be locked in such depressed condition until the sole is
leveled and the leveling-rolls are to be raised from contact with the shoe-sole.
The mechanism for locking the treadle is composed of a secondary treadle L', Figs. 1.
and 13, arranged in juxtaposition to the main treadle and secured to a longitudinally
arranged rock-shaft, mounted in suitable bearings 17, on the main treadle frame.
The rear end. portion of the rock-shaft is provided with an attached locking dog,
or pawl, so constructed and arranged that when the main treadle L is depressed,
the locking dog or pawl will, by the action of the spring 10, spring into engagement.
with a bracket or catch P, attached to a part of the main frame, thereby holding
the main treadle L in its depressed position until such time as it is desired to raise.
the leveling-rolls from the shoe-sole, whereupon the secondary treadle L! is
depressed, to rock the rock-shaft and disengage the dog or pawl from the
bracket or catch 1. By placing the foot upon the secondary treadle L', and also
upon the main treadle L, it is possible to operate the main treadle without locking
the same so long as the pressure of the foot is maintained upon both treadles.
.
In Figs. 15, 16, and 17, 1 illustrate a clutch mechanism in operative connection
with the countershaft D which serves to actuate the jack, whereby it is possible to
throw the jack out. of and into operative connection with the main drive shaft, for.
the purpose of causing the jack to stand stationary while the fore-part and shank-
rolls travel backward and forward upon the sole of the boot or shoe to the extent.
of the motion imparted to said rolls by their actuating eccentrics. For this purpose
the worm-gear d, Figs. 15, 16 and 17 is loosely mounted upon the countershaft D,
and is constructed with a hub portion d, having clutch section or teeth d³ with
which are adapted to engage the teeth de formed at one end of the clutch section d¹,
which is also provided with a clutch section or teeth d2, adapted to be engaged
with a fixed clutch section or teeth d, forming a part of the stationary bracket or.
piece d, secured in a fixed position to the main frame.
The clutch section d is keyed, or feathered, to the countershaft so that it must
rotate with the shaft, but is susceptible of being moved longitudinally thereof
through the medium of a clutch shifting lever dis mounted on a rock-shaft d
having a suitable handle do, by which the shaft can be rocked to swing the clutch-
operating lever, and thereby throw the clutch-section d either into engagement
with the clutch-section or teeth ds, or the clutch-section or teeth d³.
The rock-shaft d is designed to be locked by a spring-pin d" whenever the
clutch-section has been. shifted into engagement with the clutch-section or
teeth d or the clutch-section or teeth d

page_text: When the clutch section d" is shifted into engagement with the clutch-section or
teeth don the hub of the worm-gear, the rotary motion of the latter, produced
by the worm c, on the shaft C, which is driven by the main driving-shaft A, is
imparted to the countershaft and the jack is oscillated or reciprocated longitudinally.
Conversely, when the clutch-section d is shifted to disengage the hub d of the
worm d, and to engage the clutch-section or teeth d, the countershaft is rigidly
held against rotary motion and the jack remains stationary, while the eccentrics
serve to vibrate or reciprocate the fore-part and shank-rolls.
In Fig. 3 and 6 of the drawings it will be seen that the cylindrical carrier post *
is rotatable in the tubular post h³, so that the said carrier can be rotated for the
purpose of placing the shoe-carrying last on the pin without interference from
the toe-rest g, or other parts of the toe-post G.
The pin which engages the shoe-carrying-last is termed a "spring pin," in
that it is acted on by a spring which tends to press the pin in a forward direction,
and thereby hold the toe of the shoe in or against the toe-rest 96.
Where the toe and heel-guards are employed, the carrier h should be rotatable,
as otherwise the shoe-last could not be conveniently placed on the last pin h. By
making the carrier rotatable it can be turned so that the shoe can be put on
sidewise without interference from the toe-rest, after which the carrier is turned
back and the operator lifts the toe of the shoe onto the toe-rest. If the heel-guard
is not used, it will be obvious that the shoe can be placed on sidewise without
turning the post, but this cannot well be effected when the heel-guard is in
position, and for this reason the carrier is made rotatable, so that it can be
turned to facilitate the placing of the shoe in position.
In Fig. 18 I show a modification of the mechanism for rotating the screw d', by
which the crank or wrist-pin d is adjusted in a direction towards and from the
center of the countershaft D. In this modification, the numeral 1 indicates a roll.
or wheel to take the place of the conical roll do described with reference to
Figs. 9 and 10, and the numerals 2 indicate corrugated or undulated sides to take
the place of the conical or inclined surfaces d' and d¹³ of the cylindrical casing d".
By this means the roll or wheel 1 is positively engaged with and compelled to
rotate by the corrugated or undulated surfaces 2, thereby entirely avoiding any
tendency which the conical friction roll do might have to slip upon the conical or
inclined surfaces of the cylindrical casing.
The mechanism for adjusting the crank or wrist-pin d towards and from the
center of the transverse drive-shaft D renders it possible to change or vary the
extent of travel, or the stroke of the longitudinally oscillating or reciprocating
jack without stopping or interfering with the rotation of the main driving-shaft A,
so that the workman can, by simply operating the hand-lever e³ or e, cause the
extent of travel, or the stroke of the jack to change, or vary according to the size
or shape of the shoes or shoe-soles which are to be leveled.
The simple means provided for adjusting the shank-roll relatively to the fore-part
roll renders the rolls susceptible of proper adjustment for operating on and leveling
the soles of boots or shoes which differ widely in size.
The simple mechanism comprising the screw-shaft i, for changing or varying
the extent of travel, or the stroke of the shank-roll renders it possible to cause the
shank-roll to traverse a greater or less surface of the sole, according to the size
of the boot or shoe.
The shoe-supporting devices arranged upon the horizontally swinging frame,
supported by the laterally rocking yoke of the jack F, is very desirable, in that it
secures a compact, simple, and convenient structure wherein a boot or shoe can be
properly prepared and mounted, while the sole of another shoe, previously mounted,
is being leveled by the leveling-rolls.
The connected hand-levers arranged at opposite sides of the machines, and either
of which is capable of operating the mechanism by which the crank or wrist-pin a³
is automatically shifted to vary the stroke of the jack, is a very desirable and
important feature of my improved machine, in that it materially simplifies the

page_text: operation thereof and reduces the cost of manufacture of a sole-leveling machine
with mechanism for changing or varying the extent of motion, or the stroke of the
oscillating or reciprocating jack.
All of my present improvements are designed to perfect a sole-leveling machine,
and to provide a machine of this character which will perfectly level the soles of
boots or shoes without special care and skill from the workinan, thus relieving
him in a large measure, and only requiring the preparation of the boots or shoes,
the mounting and dismounting of the same, the depression of the treadle, the
manipulation of the devices necessary to start and stop the machinery, and the
adjustment or movement of those working parts which can be readily effected by an
unskilled person to meet all the conditions required for the particular work in hand.
My improved stroke-changing mechanism renders it possible to change or vary
the extent of motion, or the stroke of the shoe-jack without interfering with the
operation of the machine by stopping the rotation of the main driving or power-
shaft, and it is only necessary for the attendant or operator to actuate either one
of the hand levers e³ and e to make any desired change in the extent of travel of
the jack from a dead center to the utmost limit of the travel. The extent of
travel of the jack can be changed almost instantly, for the purpose of accommodating
the machine to boots or shoes of different sizes.
The changes in the motion of the jack to suit different sizes of boots or shoes
may be indicated by fingers or pointers 4, and 6, as best seen in Figs. 1 and 8,
which are secured, respectively, to the crank-arm f and rocker-arm 1', traveling
over dial-plates 5 and 7, which may be so graduated as to represent the required
adjustment for different sizes of boots or shoes.
The fingers
or pointers and dial-plates are duplicated, so that one finger or pointer
and dial-plate will be convenient to the operator at whichever side of the machine
he may be standing. For instance, when using the hand-lever e³, the operator can
conveniently observe the finger or pointer 4 and dial-plate 5, while if he is operating
the hand-levere he can conveniently observe the finger or pointer 6 and the
dial-plate 7, as will be obvious.
The dial devices described enable the required changes to be effected in a very
accurate manner for the purpose of accommodating the motions of the jack and the
motions of the shank-roll to the size of the shoe mounted on the jack.
