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 the Sole-leveling Machine for which British Letters
Patent No. 15,046, dated July 7, 1896, were obtained by Henry Harris Lake, as a
communication from Messrs. Edward Charles Judd and Harry Edgar Cilley, both
of Boston, County of Suffolk, and State of Mass., United States of America.
The chief objects of the present invention, concisely stated, are to simplify and
render the machine more efficient in operation and susceptible of more general use
in leveling the soles of boots and shoes; to provide new and improved means of
a simplified character for rocking the jack longitudinally; to provide novel means
for varying the relative motions of the jack and the shank-rolls; to provide novel
means for supporting and adjusting the angles of inclination of the parts or sections
composing the shank and forepart rolls; to provide means whereby the toe and
heel-posts of the jack are adjustable laterally and longitudinally to secure correct
action and uniform pressure of the leveling rolls on soles which vary in size or
shape; to avoid tipping of the leveling rolls and thus secure uniform pressure of
the same upon soles which vary more or less in contour; and to provide novel,
simple and efficient means for correctly adjusting and centering the lasted shoes
with relation to the jack and rolls of a sole-leveling machine, whereby the pressure
and action of the rolls will be substantially uniform on all soles presented to the
same.
To accomplish all these objects, our invention involves the features of construc-
tion, the combinations or arrangements of parts, and the principles of operation
hereinafter described and claimed, reference being made to the accompanying

In order to enable those skilled in the art to make and use our invention, we
will now describe the same in detail, referring to the drawings, wherein the
numerals indicate the main frame, which may he of any construction suitable
for the purpose in hand. The lower portion of the main frame is provided with
suitable bearings in which is arranged a horizontal main driving shaft 2 having
at one end a pinion 3, Figs. 2 and 3, meshing into a comparatively large spur gear
such that the required rotary motion is transmitted to the shaft 8 from the main
frame. The spur gear wheel 4 is provided at its inner side with a rigidly attached
pinion 6, meshing into a spur gear wheel 7, secured to one end of a shaft 8, and
of substantially the same diameter as the spur gear wheel 4, the construction being
such that the required rotary motion is transmitted to the shaft 8 from he main
driving shaft 2. The shaft 8 is provided with an eccentric 9, Fig. 1, with which
engages one end of an eccentric strap or rod 10, pivoted at its other end through
the medium of a horizontal pin 12 to a clamp 13 which is forked to provide a
dove-tail groove or way 14 engaging and slidable upon a dovetailed arm 15
secured or formed with the rocking jack frame 16, and preferably arc-shaped, as
shown in Fig. 1. The forked clamp 13 is adjustable to different positions upon
the arc-shaped arm 15 and is held in a fixed position with relation to this arm,
after adjustment, through the medium of a clamping screw 17, which is carried
The frame of
by the clamp and is adapted to bear against the arc-shaped arm.
the jack is mounted upon a jack supporting shaft 18 and the rotary motion of the
shaft 8, through the medium of the eccentric strap or rod 10, imparts a longi-
tudinal rocking motion to the jack frame, as will be obvious. The extent of
motion or throw of the jack frame can be accurately and nicely regulated or
varied by adjusting the forked clamp 13 upon the arc-shaped arm 15.
Instead of making the arm 15 arc-shaped or segmental, as shown in Fig. 1, we
may provide the jack-frame with a rectilinear arm 15ª, as shown in the modified
construction, Fig. 19. The rectilinear arm 15* is dovetailed the same as the
arm 15, and the forked clamp 13 pivoted to the strap or rod 10 by pivot pin 12, is
adjustable on the arm 15", substantially the same as described with reference to
the adjustment of the fixed clamp on the arc-shaped arm 15.
The yoke-shaped frame 19, on which the forepart leveling roll 20 is mounted as will
hereinafter appear, is pivoted at its rear end to the top portion of the main frame 1,
and is connected by a rod 21 with the treadle frame 22, as in the former patent,
so that the yoke-shaped frame can be forced downward. The carrier-frame 23,
of the fore-part leveling roll is connected by a rod 24 with one arm of a bell-
crank-lever 25, the other arm of which is connected by a rod 26 with an eccentric

page_text: on the main driving shaft 2, which latter is provided with a belt-pulley 27, by
which it can be rotated by suitable power, as in the former patent. The yoke-
shaped frame 28, on which the shank roll 29 is mounted, as will hereinafter appear,
is adjustably connected with a main yoke-shaped frame 28", substantially as shown
and described in the patent before mentioned. The frame 28, is connected with
one arm of a bell-crank-lever 30, the same as in the former patent, and the other
arm of this bell-crank-lever is connected by a rod 31 with am eccentric on the main
driving shaft 2. The bell-crank-lever 30 is pivotally mounted in the upper end
of a rocker-frame 32 supported by a shaft 33. The rocker-frame 32 is provided
with a dovetailed arm 34, preferably arc-shaped and of substantially the same
construction or form as the dovetailed arm 15. This arm 34 is provided with a
forked clamp 35 pivoted to one end of an eccentric strap or rod 36 engaging an
eccentric 37 on the jack-operating shaft B. The forked clamp 35 is adjustable on
the arc-shaped arm 34 and is held in any position of adjustment through the
medium of a clamping screw 38 in substantially the same manner as the forked
clamp 13 is adjustably held upon the arc-shaped arm 15 of the jack. The
eccentric 37 serves to raise and lower the eccentric strap or rod 36 whereby the
rocker-frame 32 is oscillated or rocked. The rocking motion of the rocker-
frame 32 is imparted to the bell-crank lever 30 and since the latter is oscillated
or vibrated on the rocker-frame through the medium of the rod 31 actuated by
the main driving shaft, a longitudinally traversing motion is imparted to the
yoke-shaped frame 28 and the shank-roll, while at the same time this yoke-shaped
frame and the shank roll are vibrated longitudinally by the movements of the bell-
crank lever 30, so that a compound motion is imparted to the rollers 29. That is to
say, the rollers are not only moved longitudinally of the shoe with what may be
called a traversing motion, but as they traverse this pathway they are more or less
rapidly vibrated. If the rocker arms were stationary, for instance, the bell-crank
lever 30 would simply impart the more or less rapid vibration to the rollers 29
within a fixed pathway, but since the bell-crank-levers 30 will vibrato while they
are being swung back and forth by the rocker arms 32, the rollers 29 are not only
more or less rapidly vibrated, but are caused to travel along the length of the
shoe sole.
The extent of motion or throw of the rocker frame 32, and consequently the
extent of the longitudinal traversing motion of the frame 28 and the shank-roll is
susceptible of being conveniently and quickly regulated or varied by simply
adjusting the forked clamp 35 on the arc-shaped frame, 34, The adjustment of
the forked clamp in one direction lengthens the throw of the rocker-frame and
conversely the adjustment of the forked clamp in the opposite direction shortens
the throw of the rocker-frame, as will be obvious without further explanation.
The connections described and shown between the jack operating shaft 8 and ne
jack-frame 16 and rocker-frame 32, provide very simplified means for regulating
and varying the throw of the jack and the traversing motion of the shank-roll,
whereby the relative positions of the jack and shank roll can be altered at will
and the latter can be made to pass up on to the toe of the sole, cu back on to the
heel portion thereof, a greater or less distance, as circumstances may require.
Instead of making the arm 34 arc-shaped or segmental, as shown in Fig. 1,
we may provide a rectilinear arm 34" on the rocker-frame 32, as shown in the
modification Fig. 20. The forked clamp 35, pivotally connected with the strap
or rod 36, is adjustable on the rectilinear arm 34, the same as described with
reference to the adjustment of the forked clamp on the arc-shaped arm. 34.
The yoke-shaped frame 28 is connected by a rod 39 with the treadle frame 22,
for the purpose of forcing said frame and the shank-roll downward, as usual.
The treadle frame 22, the counterbalance weight 40, and the connections between
the treadle frame and the weight, are preferably constructed the same as disclosed
in the former patent, but any suitable treadle mechanism may be employed.
The jack frame 16 is provided with a laterally movable frame 41, preferably
composed of two angularly arranged shoe-supporting arms 42 and 43, Fig. 1

page_text: constructed, arranged and pivotally mounted substantially the same as in the
former Patent, and each designed to carry toe and heel-posts and a toe-guard, as
hereinafter explained, but as regards this part of our invention, a single shoe
supporting arm may be employed. We prefer, however, to use the two angularly
arranged arms in that while one arm supports a boot or shoe under the leveling
rolls the other arm is in a position to enable a boot or shoe to be placed thereupon
in readiness to be moved into position under the leveling rolls at the proper time.
Inasmuch as both arms and the heel and toe-posts and other parts carried thereby
are of like construction, we will merely describe the parts belonging to one of the
arms as this is sufficient to enable this part of the invention to be clearly under-
stood. The arm, as for example, the arm 42, is constructed or provided on its
upper side with a horizontal dovetail guide or way 44 engaging a dovetail
groove 45 provided longitudinally in a slide-block 46, Figs. 4 and 5, having on its
apper side a dovetail guide or way 47 extending transversely with respect to the
armi 42. The dovetail guide or way 47 engages a dovetail groove 48 formed in the
base plate 49 of a heel-post standard 50. The slide-block 46 is adjustable longi-
tudinally of the shoe-supporting arm 42, and is held rigid in a fixed position after
adjustment through the medium of a clamping screw 51 carried by the slide-
block and adapted to bear at its inner end against the dovetail guide or way 44.
The base plate 49 carrying the heel-post standard 50 is adjustable in engagement
with the dovetail guide or way 47 in a direction transversely of the shoe-support-
ing arm 42, or rather in a direction at right angles to the direction in which the
slide-block 46 is adjustable. The base plate 49 is held rigid after adjustment
through the medium of a clamping screw 52 carried by the base plate and bearing
at its inner end against the dovetail guide or way 47, the same as described with
reference to the clamping screw 51. The lower portion of the heel-post standard 50
is externally screw threaded, as at 53, to engage an internally screw threaded
sleeve 54 having a suitable handle 55 by which it may be turned upon the standard
and be thereby raised or lowered. The sleeve 54 is constructed at its upper end
portion with a spiral incline, as at 56, which bears against the base or lower end
of a quick-pitch screw thread 57 provided upon a sleeve 58 fitting the standard 50.
Acking plate 59, secured by screws to the sleeve 54, laps over the quick-pitch
screw thread 57 and holds the sleeve 58 in operative connection with the sleeve 54.
The face of the locking plate 59 which engages the quick-pitch screw thread
should be properly beveled to fit the thread and permit the necessary motion of
the sleeve 54, the construction being such that when the handle 55 is operated to
turn the sleeve 54, the locking plate 59, acting upon the quick-pitch screw thread 57,
causes the sleeve 58 to be lowered when the sleeve 54 is turned in one direction,
and to be raised when said sleeve is turned in the opposite direction, by means of
the spiral incline 56. The upper end of the standard 50 is provided with a trans-
verse pin 60 which serves as a pivot for a last-pin-holder 61, preferably forked to
receive the base or block 62 of the last-pin 63. The base or block 62 of the last-
pin is held between the arms or members of the forked holder 61 by mean of a
clamp screw 64. This clamping screw is arranged longitudinally, or at right
angles to the pivot-pin 60 and the last-pin 63 is susceptible of being oscillated or
rocked laterally to any required position after which it can be securely held in
position by tightening the clamping bolt. The last-pin-holder 61 is susceptible
of rocking or tipping longitudinally and is pivotally connected by a link 65 with
the upper end of the sleeve 58 in such manner that when this sleeve is raised or
lowered by operating the handle 55, as before explained, the last-pin-holder 61
will be swung longitudinally on or with the pivot-pin 60. The longitudinally
and laterally adjustable last-pin enables the boot or shoe to be accurately adjusted
and centered in the manner and for the purposes more fully hereinafter explained.
In the modified construction, Figs. 6 and 7, the last-pin 63 is provided with a
Bifurcated base or lower end 62 arranged upon a clamping screw 64" passing
through a last-pin-holder 61 mounted on the upper end of the heel-post stan-
dard 50 through the medium of a transverse pivot-pin 60°. The last-pin-holder 61"

page_text: The
is pivotally connected by a link 65" with a sleeve 58" constructed and operated in
the same manner as described with reference to the sleeve 58, Figs. 4 and 5.
clamping screw 64" passes through the transverse pivot-pin 60" for the purpose of
placing the pivot of the last-pin as near as possible to the last where the latter
rests upon the base of the last-pin, so that when the last is jacked, as hereinafter
explained, it will not be moved bodily forward an undue extent, but will be tipped
upon or with the pivot-pin 60".
The toe-post standard 66 is provided in its base portion with a transverse dove-
tail groove 67 engaging a transverse dovetail guide or way 68 formed on the upper
side of the slide-block 69 which is movable longitudinally on the dove-tail guide
The slide-block 69 is provided with a
or way 44 of the shoe-supporting arm 42.
clamping screw 70 bearing at its inner end against the dovetail guide or way 44
for the purpose of rigidly holding the slide-block in any position to which
adjusted. The lower portion of the standard 66 is also provided with a clamping
screw 71 bearing at its inner end against the transverse guide or way 68, whereby
it is possible to adjust the standard laterally and rigidly lock it in position after
the desired adjustment is effected. The toe-post standard is constructed with a
vertical cylindrical bore 72 in which is arranged a screw threaded shank 73 having
a head 74 at its upper end. This head contains a recess or socket in which is
arranged a toe-rest 75 preferably supported by a transverse pin 76 secured to the
head 74 of the screw threaded shank. The upper end of the standard 66 is pro-
vided with a rotatable hand-nut 77 engaging the screw threaded shank 73, which
latter is provided with a cross pin 78 which prevents it from turning when the
band-nut is rotated to raise or lower the shank. The standard 66 is provided with
a lub 79 on which a spur gear 80 is adapted to rotate. This spur gear engages a
pinion 81, having a central screw threaded orifice engaging the vertical screw
threaded shank 82 of the toe-guaru 83. The smooth part of the shank of the toe-
guard passes through a socket 84 forming a part of the head 74 and the toe-guard
is provided with a pendent stem 85 engaging an orifice SG in the head 74, for the
purpose of preventing the toe-guard and its shank from turning. The pinion 81 is
rotatably held upon the base portion of the standard 66 through the medium of a
locking plate 87, secured in position by suitable screws or otherwise. The pinion 81
is rotated by manually rotating the spur gear 80, and by this means the toe-
guard 83 can be accurately and nicely adjusted with relation to the toe-portion
of the sole being leveled. The lower end of the screw threaded shank 82 is guided
by a socket 88 to which the locking plate 87 is secured. By the construction and
arrangement of parts described and shown, the toe-post is susceptible of being
accurately and nicely adjusted longitudinally and laterally in a manner similar
to or the same as the heel post.
If the handle 55, of the heel-post be turned in the proper direction the sleeves 54
and 58 will be raised and the last-pin-holder 61 will be tipped forward for the
purpose of forcing the toe of the shoe down upon the toe-rest 75.
In the operation of a sole-leveling machine, such as disclosed in the Patent before
mentioned, when soles of certain contour are operated upon, the fore-part roll
tends to tip the boot or shoe and force it out of the toe-rest, and the roll also
unevenly presses upon opposite sides of the sole. This is avoided by our present
In Fig. 16, a last is
invention, as we will now proceed to explain in detail.
indicated by full lines mounted upon the last-pin 63, the pin-hole of the last being
drilled straight therein, or at right angles to the surface which bears upon the
last pin-holder. The surface of the fore-part of the shoe-sole indicated in Fig. 16,
extends at an angle in such manner that the right-hand side is measurably higher
than the left-hand side. If a shoe of this contour is placed in an ordinary sole-
leveling machine the leveling rolls tend to tip and force the shoe out of the toe-
rest, while at the same time an uneven pressure is placed upon opposite sides of
the sole. To counteract this, the last-pin of our improved machine is tipped
laterally to the position indicated by dotted lines, Fig. 16, whereby the surface of
the fore-part of the sole is made substantially level and the two sides of the sole

page_text: are at about the same height, so that the leveling roll will bear evenly and
uniformly upon the entire surface of the fore-part. This adjustment of the last-
pin 63 is effected by shifting or swinging the pin laterally and then clamping it
in its adjusted position through the medium of the clamping screw 64, Figs. 4
and 5, which prevents the pin from turning very easily, but at the same time
enables the angle of inclination to be varied by the operator tipping the last to the
required position while the shoe is not jacked and firmly held against the toe-
rest 75. When the boot or shoe is jacked by tilting the last-pin longitudinally,
the last-pin is locked firmly in position, as regards lateral motion, by frictional
contact between the base of the last-pin and the last-pin-holder 61. By this means
the last-pin can be conveniently adjusted laterally while the shoe is unjacked, but
is locked firmly in position against lateral motion when jacked and subjected to
the action of the leveling rolls.
In Fig. 17, the pin-hole in the last is represented as drilled crooked, or at an
acute angle to the part of the last which rests against the last-pin-holder. This
Figure indicates by full lines the position first assumed by the last when placed
upon the last-pin, and by dotted lines, the position to which is is adjusted by tipping
the last pin laterally, to place the sole approximately level, whereby an even,
uniform pressure will be exerted thereupon by the levelling rolls.
In Fig. 18 is indicated the manner in which a boot or shoe is adjusted and
centered through the medium of the lateral adjustment of the toe and heel-posts.
This figure indicates by full lines the position assumed by the boot or shoe when
placed in the machine with the heel and toe-posts centrally thereof. The line a-b
indicates the center line of the machine and the parts marked with the reference
letters and indicate the toe-rest and the last-pin, respectively. A comparison
of the outline of the boot or shoe, sole indicated by full lines, with the center
line ab shows that one side of the sole is much nearer the center line than the
other side, in consequence of which the leveling rolls will not bear evenly and
uniformly upon the surface of the sole, so that the best results are not obtained.
To avoid this objection and to accurately and correctly adjust and center the shoe,
the toe and heel-posts are laterally adjusted in the manner hereinbefore described,
whereby it is possible to shitt the shoe from the position represented in full lines
to the position indicated by dotted lines in Fig. 18. By this adjustment the twa
longitudinal side portions of the sole are made approximately equal at opposite
sides of the center line a-b, and consequently the action and pressure of the
leveling rolls will be even and uniform. This part of this invention is very advan-
tageous and inasmuch as my foreign correspondents believe themselves to be the
first to provide means for accomplishing the results stated, I do not wish to be
understood as confining myself to the particular construction and arrangement
of parts represented in the drawings.
As best seen in Fig. 10, the shank leveling roll 29, is made in two parts or
sections, somewhat conical in form or shape, and mounted to turn or rotate upon
stads fixed to the lower ends of the arc-shaped or segmental plates 90 having seg-
mental slots 91. The front portion of the yoke-shaped frame 28 is provided with
a head 92 having a pendent arm or hanger 92 carrying at the lower end a pivot-
pin 93, and on this pivot-pin, between the head 92 and the pendent arm or
hanger 92, is pivotally mounted a vertical plate 94 preferably of the segmental
outline clearly shown in Fig. 12. This plate is mounted on the pivot-pin 93
through the medium of an eye or socket 95, formed centrally of the plate, so that
the latter can rock laterally. The top portion of the plate is provided with a pin
hole 96, adapted to receive a soring-pressed pin 97, movable horizontally in the
pendant arm or hanger 92 and having a suitable handle or knob 98 by which it
can be drawn outward against ne tension of the spring 99 for the purpose of dis-
engaging the pin from the pin-hole, so that it is possible, by holding the pin
retracted, for the plate 94 to freely oscillate or rock laterally. The curved arms
c' the plate 94 are each provided with two bolt holes 100 and 101 and the segment-
ally slotted plates 91 are arranged vertically on the plate so that they can be

page_text: adjustably clamped thereupon through the medium of guide-bolts 102 and clamp-
ing bons 103. The bolts 102 engage the bolt-holes 101 and the clamping bolts 103
pass through the segmental slots 91 and screw into the bolt-holes 100, as will be
clearly understood by reference to Fig. 13. By unscrewing the clamping
bolts 103, the segmentally slotted plates 90 can be adjusted in circular paths for
the purpose of varying the angles of inclination of the axis of the parts or sections
composing the shank-roll, after which the segmental plates can be rigidly secured
in their position, of adjustment by tightening the clamping bolts, as will be
obvious. By the mean's described, the angle of the parts composing the shank roll
can be conveniently and quickly adjusted according to the conditions required in
operating on soles which vary in contour. The plate 94 can be locked rigid to
the head 92, and consequently to the yoke-shaped frame 28, by the pin 97, so that
the shank-roll is held rigid as regards lateral oscillation, or the shank roll may be
left free to tip or tilt laterally during the leveling operation. If the shank-roll is
to be held rigid the spring-pin 97 is caused to engage the pin hole 96, and conversely
if it is desired that the shank-roll should be free to tip or tilt laterally the spring-
pin 97 is withdrawn and held from engagement with the pin-hole 96 so that the
plate 94 and the shank-roll are free to rock laterally.
The shank-roll 29, mounted and adjustable in the manner above described, is
susceptible of being raised and lowered for the purpose of varying its height
relatively to the jack. This is accomplished by providing the head 92ª with a
swiveled screw-shaft 104, Fig. 11, engaging a screw thread socket 105, projecting
pward from the front end of the frame 28, in such manner that by turning the
screw shaft 104 in one direction the head 92 and shank-roll 29 will be raised and
by turning the screw-shaft in the opposite direction the head and shank roll will be
lowered. The screw-shaft 104 may be turned in any suitable manner, but I
prefer to construct its upper end with an angular head 106 to receive a wrench,
by which the shaft can be conveniently and quickly rotated in either direction.
As best seen in Fig. 14, the fore-part-leveling roll 20 is made in two parts or
sections somewhat conoidal in shape and mounted to turn or rotate upon studs
fixed to the lower ends 107 of two segmental or arc-shaped plates 108 having
segmental slots 109. These segmental plates are mounted upon a support 110,
similar to plate 94, Fig. 12, having, a vertical front face and pivotally mounted
at its lower end on a stud-bolt 114, upon the carrier frame 23 which is pivotally
mounted in a yoke-shaped frame 19. The segmental plates 108 are each secured
in position through the medium of a guide-bolt 112 and a clamp bolt 113, the same
as the bolts 102 and 103, Figs. 10 and 13, whereby the segmental plates can be
adjusted in circular paths and subsequently be rigidly locked in fixed positions by
tightening the clamping bolts 113 and 112. By this means the axes of the two
parts or sections of the fore-part-leveling roll can be made to stand at varying
angles of inclination relative to each other, whereby the roll is susceptible of
adjustment to correctly operate upon the shoe soles which widely vary in contour.
The support 110, like plate 94, is pivotally mounted at its lower end on a stud-bolt
114 and is provided with a spring-pressed pin 115, by which it can be locked to or
5 released from the carrier frame 23, substantially as described with reference to the
plate 94, Figs. 10 11 and 12.

The present invention materially simplifies the construction and operation of
the machine and renders it susceptible of more general application for leveling
