ALFRED JULIUS BOULT of the firm of W. P. Thompson & Boult Agents for
Foreign Patent Solicitors, of 323 High Holborn in the County of Middlesex
and 6 Lord Street Liverpool in the County of Lancaster, " IMPROVEMENTS IN
MACHINES FOR PASTING TOGETHER SHOE UPPERS [A communication to him from
abroad by S Lloyd Wiegand of Philadelphia United States of America.]
"
This invention relates to an improved machine for pasting together the parts of
shoe uppers preparatory to sewing and lasting them and it consists in a series of
forms blocks, or moulds upon which the parts are placed as they serially pass
before clamping, pasting and smoothing devices and gripper and frames which, by
devices similar to the register points and gauges used in printing, place the several
parts in exact position and thus insure the exact and rapid assembling of the
several parts forming the shoe upper.
In a suitable frame is mounted a horizontal circular table rotating with a
vertical shaft and supported by a large bearing fitting around an enlargement or
boss formed on the underside of the table.
In the upper face of the table are formed equidistant radial slots in shape like an
inverted capital block letter T; these slots should be made so as to fit corre-
spondingly shaped slides attached to the underside of moulds or forms of the shape
of the interior of a shoe or gaiter upper before the same is lasted and as spread
open far enough to place all of the parts involved in the seam uniting the vamp to
the quarters or sides in convex form; said forms are made perforated or of porous

page_text: material at the parts near the seam in order to expedite the drying of the paste.
Inverted Tshaped heels thereon are made to fit accurately in the slots in the table,
so as to slide freely therein but not to shake or vibrate laterally; in each of the
forms there is a hole made perpendicularly in the centre near the heel end of the
form and should be made accurately of the same diameter and at the same distance
from the heel in all of the forms used upon the same machine for the same size and
pattern shoe upper.
Through the table at equal distances from the centre and centrally in each of
the slots are fitted a series of vertically sliding bolts guided at their lower ends by
passing through holes in a plate or wheel securely fastened upon the vertical shaft
and raised by means of spiral springs surrounding the same, which rest at their
lower ends on a plate or wheel, their upper ends pressing against trammels or
clamps secured upon the bolts previously described
Each trammel bears a roller adapted to pass under an inclined plane or stationary
cam by which at the proper time they are depressed; the bolts are prevented from
turning and so caused to present the rollers properly to the action of the cam by
projections formed on the trammels sliding in grooves formed in the vertical shaft
parallel with the axis thereof.
When held up by the springs the bolts engage in holes in the forms and hold
them in position in the table when depressed by the stationary cam they are
disengaged from the forms and permit the same to be disengaged from the table
by the shaped slides sliding outward in the radial grooves or slots of the
revolving table.
A series of springs shaped like an inverted capital letter U are secured by one
end near the centre of the revolving table and have their free ends resting against
the parts of the forms directly below the heel of the uppers and are so set and
adjusted as to project the forms from the table when the bolts are retracted or
depressed by the operation of the stationary cam.
The adjustment of the stationary cam, the bolts, and parts connected therewith
in relation to the revolving plate and table is such that, as the table is turned
each bolt is successively retracted so as to clear the form upon which the operation
of pasting and clamping has been completed and then shaped spring discharges
that form from the revolving table upon a carrying or conveying table which
turns slowly upon an upright axis and receives the several forms with their uppers
and holds them whilst the drying and absorption of moisture proceeds sufficiently
to permit of the separation of the form and the clamps hereinafter described from
the uppers.
An endless apron or belt may be substituted for the conveying table.
Upon the periphery of the revolving table are formed teeth in number equal to
a multiple of the number of the T shaped slots into which gears an idle or
transmitting wheel propelling another wheel of such number of teeth as to be
evenly divided by the same multiple as the number of teeth in the periphery of
the revolving table. Upon the upper end of the same vertical shaft as the second
wheel above mentioned, and turning therewith, is a third table upon which is
secured a series of springs arranged in sets of three or more (four is preferable) and
serving to receive and hold a second set of forms in position. These forms are
made of metal and of the shape of the vamp or front portion of the shoe upper, and
are provided with ears or projections which, resting upon shoulders of the springs
on the third table referred to, hold the forms in position and also engaging in
springs on the forms of the first set serve to hold and clamp the two forms together
and hold the vamp and quarters during the operation of drying.
Upon the second forms are placed registering gauges or pins which serve to
guide the leather vamps and determine their position; the gauges or pins are
attached by springs which, yielding, permit the pins to recede when the vamps are
applied to the quarters of the upper
The rotary motion of the two tables first and last herein mentioned is inter-
mittent and derived from a cam engaging in notches of peculiar form in the rim

page_text: of the plate below the revolving table on which the spring bolts rest and is
transmitted from the teeth on the rim of the revolving table through the idle
wheel to the second wheel as above indicated; the operation of the cam is like that
of the device known to clock and watch makers as the "Geneva stop motion
"
The cam is mounted upon and turns with a shaft turned by a bevel cog wheel
driven by a bevel pinion on a shaft provided with the usual fast and loose pulleys
adapted to receive power from an endless band or belt.
The connection between the bevel pinion and the pulley shaft is effected by a
clutch so beveled as to tend to unclutch and is held in connection by a pair of
toggle levers held in a straight position for engaging by a spring latch and can
be re-engaged after having been liberated by pressure upon a pedal.
Upon the pulley shaft is mounted (so as to slide upon and turn with the shaft)
a wheel having a rim of leather which may be pressed against the side of the
beveled cog wheel opposite to the bevel pinion on a smooth rim above the teeth
by means of a treadle and is automatically retracted by a weighted arm. This
wheel with the leather rim enables the operator at pleasure to turn the machine
backward when the bevel pinion is disengaged.
A stencil mounted adjustably
upon an arm so as to rise and fall by the action of a second cam on the cam shaft
covers the part of the upper upon one of the first forms exposing only such portions
as are to receive paste the adjustment of the second cam is such as to raise and
hold the stencil clear of the form during the rotary motion of the revolving. table.
Contiguous to the front of the form covered by the stencil are placed two paste
fountains with scrapers and brushes combined.
The fountains are upright vessels having inclined wings or vanes fastened on
their inside and a rotating vertical shaft provided with vanes inclined in an
opposite direction from the vanes of the vessel the direction of the motion of the
shaft and vanes is such that the paste by their combined action is kept thoroughly
stirred and pressed downward; the rotary motion of the shaft is imparted by an
easily detachable clutch or coupler from an upright shaft and suitable belt gear
connecting the latter with the pulley shaft.
A spout or arm extends from each paste fountain and is made flexible so as to
rise and fall to a limited extent and at the end terminates in an upright chamber
or cylinder from the bottom of which protrudes a brush having a centre formed
of bristles between which paste is forced and around which bristles are placed
steel scrapers enclosed in a sheath of India Rubber. The scrapers roughen the
exposed part of the leather and insure the penetration of the paste and the India
Rubber covering or sheath prevents the paste splashing or wasting between the
scrapers; the brushes are rotated from the shafts by means of cords and pulleys
The fountains and arms or spouts with their connected brushes and scrapers
turn about the axis of a shaft so as to apply paste to the exposed portions of the
lining and quarters that protrude through the stencil such motion being derived
from the cams on the cam shaft.
The paste fountains are attached by thumb screws to the frame and are readily
removed and attached so as to be easily cleaned.
The second set of moulds or forms bearing vamps are transferred from the third
table by a pair of elastic arms turning with a rock shaft whilst the tables are
stationary the motion of the rock shaft is derived from a pinion driven by a sector
moved by a cam on the cam shaft. The said pinion is not rigidly secured to the
rock shaft but is connected by a clutch having teeth beveled in both directions
this clutch has one member fastened to the rock shaft and the other member
fastened to or formed on the side of the pinion against which it is pressed by a
spring of sufficient tension to overcome all normal resistances in transferring the
second form and "vamp to the first form and the "quarters" when through
accident any undue-resistance is encountered the pinion bearing against a bearing
turns without turning the rock shaft but instead causes it to move endwise and by
means of a lever liberates a spring and releases toggles, unclutches the driving
pinion and stops the machine. When the vamp is applied to the quarters the
23

page_text: guides or pins being supported by their springs yield and recede so as to permit
close contact of vamps and quarters and the second form clamps them firmly
together by engaging the projections in the springs on the first forms.
In a modified form of the machine instead of the circular table an endless band
formed of plates hinged together in the manner of the travelling platform of a
"railway Horse power" is used to convey the first forms and the intermittent cam
motion for progessively moving it is applied to the reels or cylinders upon which
it turns.
The operation of the machine is as follows: the quarters and inner lining
having been previously sewed and turned are placed in the forms and successively
placed in the machine with the T shaped slides of the first forms in the slots of
the revolving table; the spring bolts engaging in the holes in the first form, they
successively pass, by the intermittent motion of the revolving table to the stencils
and pasting devices where they receive a coat of paste on the parts exposed and at
the next step receive a second form containing a vamp which form clasps, by its
projections, upon the springs of the first form in which it is securely held; upon
further rotation of the table the spring bolts are retracted and the forms containing
the parts pasted in exactly registered position are discharged by the springs upon
the second table. A counter or register may be added to record the work done by
the machine and also a second counter to record the number of times that the
clutch is liberated so as to determine the amount of work done by the machine.

SHOE UPPERS a communication to me from abroad by S. Lloyd Wiegand of
Philadelphia, United States of America.
"
The nature of this Invention consists in a series of forms, blocks or moulds upon
which the parts are placed as they serially pass before clamping, pasting and
smoothing devices, and gripper and frames which, by devices similar to the register
points and gauges used in printing, place the several parts in exact position and
thus insure the exact and rapid assembling of the several parts forming the shoe
upper as hereinafter fully shown.
Figure 1 of the drawings shows a plan of the machine;-Figure 2 a front
elevation; Figure 3 a side elevation; Figure 4 a vertical section in the plane
indicated by the line xx in Figure 1; Figure 5, a section in the plane indicated by
the dotted line y y in Figure 1; Figure 6, a section in the plane indicated by the
dotted line zz in Figure 1; Figure 7, an elevation partially in section of the pasting
fountain and brush, and scrapers connected therewith, the paste-fountain drawn on
enlarged scale. Figures 8. 9 and 10 show projections in plan, front and side
elevation in which the several mechanisms are differently assembled and the
remaining figures show the several parts in detail on enlarged scale.
The same letters of reference apply to the same parts in the several figures.
A represents the frame of machine; B, a large horizontal circular table rotating
with the shaft, B₁, and supported by a large bearing, B2 fitting around an
enlargement or boss, B³, formed on the under side of the table B. In the upper
face of the table B are formed equidistant radial slots B4, in shape like an inverted
capital block letter T. These slots should be made accurately of the same dimen-
sions, so as to fit correspondingly-shaped slides (marked C¹) attached to the under
side of the molds or forms C. The forms C are the shape of the interior of a
shoe or gaiter upper before the same is lasted and as spread open far enough to
place all of the parts involved in the seam uniting the vamp to the quarters or
sides in convex form, and are made perforated or of porous material at the parts
near the seam in order to expedite the drying of the paste. The inverted-T
shaped slides C are made to fit accurately in the slots B* in the table B, so as to
slide freely therein but not to shake or vibrate laterally. In each of the forms C
is a hole Č³, made perpendicularly in the centre near the heel end of the form and
should be made accurately of the same diameter and at the same distance from the
heel in all the forms used upon the same machine for the same size and pattern of
shoe upper.
Through the table B, at equal distances from the centre and centrally in each of
the slots B4; are fitted a series of vertically-sliding bolts B5. These bolts B5 are
guided at their lower ends by passing through holes in a plate or wheel, B6, securely
fastened upon the shaft B' and are raised by means of spiral springs B', which rest
at their lower ends on the plate B6, with their upper ends pressed against trammels
or clamps Bs, secured upon the bolts B³. The trammels B³ each bear a roller, B³
adapted to pass under an inclined plane or stationary can, B10, by which at the
proper time they are depressed. The bolts B³ are prevented from turning and so
aused to present the rollers B³, properly to the action of the cam B₁ by.

page_text: projections B, formed on the trammels B8, sliding in grooves B¹ formed in the
shaft B', parallel with the axis thereof.
When held up by the springs B7. the bolts B5 engage in the holes C³ in the
form C and hold them in position in the table B. When depressed by the cam B¹º
they are disengaged from the forms C and permit the forms C to be disengaged
from the table B by the slides C' sliding outward in the radial grooves or slots B*.
A series of springs B13, shaped like an inverted capital letter U are secured by one
end near the centre of the table B, and have their free ends resting against the
parts of the form C directly below the heel of the uppers and are so set and
adjusted as to project the forms C from the table B when the bolts B³ are retracted
or depressed by the operation of the cam B10. The adjustment of the cam B¹º,
rollers B, bolts B5 and springs B7 in relation to the plates B6 and table B is such
that as the table B is turned each bolt is successively retracted so as to clear the
form C upon which the operation of pasting and clamping has been completed and
the spring B¹s discharges that form from the table B upon a carrying or conveying
table D, which turns slowly upon an upright axis and receives the several forms
with their uppers upon them and holds them while the drying and absorption of
moisture proceed sufficiently to permit of the separation of the form C and the
clamps G hereinafter described from the uppers. An endless apron or belt may be
substituted for the wheel D.
Upon the periphery of the table B are formed cog teeth, in number equal to a
multiple of the number of the slots B4 into which gears an idle or transmitting
wheel propelling another wheel F of such number of teeth as to be evenly divided
by the same multiple as the number of teeth in the wheel B. Upon the upper end
of the same vertical shaft, F', as the wheel F, and turning therewith is a table, F².
Upon this table is secured a series of springs, F3, which are arranged in sets of
three or more, (four are preferable) and serve to receive and hold the forms G in
position. The forms G are made of metal and of the shape of the vamp or front
portion of the shoe upper, and are provided with ears or projections G², which
resting upon the shoulders F, of the springs Fs, hold the forms G in position and
also engaging in springs C³ on the form C, serve to hold and clamp the forms G
and C together and hold the vamp and quarters when placed in and on them, in
the manner hereinafter described during the operation of drying.
Upon the forms G are placed registering gauges or pins G², which serve to guide
the leather vamps G³ and determine their position with precision in the form G.
The gauges or pins G2 are attached by springs G (shown in dotted lines in
Figure 17) which, yielding, permit the pins G² to recede when the vamps are
applied to the quarters of the upper, as will hereinafter appear.
The rotary motion of the tables B and F is intermittent and derived from a
cam, H, engaging in notches of peculiar form in the rim of the plate B6, and is
transmitted from the teeth on the rim of the table B through the wheel E to the
wheel F. The operation of the cam H (shown in Figure 18) in the wheel or
plate B is like that of the device known to clock and watch makers as the
"Geneva stop-motion." The cam H is mounted upon and turns with a shaft H¹
turned by a bevelled cog wheel driven by a bevelled pinion, H³, on a shaft H*
provided with the usual fast and loose pulleys Hand H', adapted to receive power
from an endless band or belt. The connection between the pinion H³ and the
shaft His effected by a clutch Hs, so bevelled as to tend to unclutch and is held in
connection by a pair of toggle levers H, which is held in a straight position for
engaging by a spring-latch, H10, and can be re-engaged after having been liberated
by pressure upon the pedal H".
Upon the shaft H* is mounted, so as to slide upon and turn with the shaft, a
wheel, H2, having a rim of leather which may be pressed against the side of the
bevelled wheel H2 opposite to the pinion H³ on a smooth rim above the teeth by
means of a treadle H¹³ and is automatically retracted by the weighted arm H.
This wheel enables the operator at pleasure to turn the inachine backward when
the pinion H³ is disengaged. A stencil, J, mounted adjustably upon an arm J', so

page_text: as to rise and fall by the action of a cam, J³, on the shaft H¹, covers the part of the
upper upon a form, C, exposing only such portions as are to receive paste. The
adjustment of the cam J2 is such as to raise and hold the stencil J clear of the form
during the rotary motion of the table B.
Contiguous to the front of the form covered by the stencil J are placed two paste
fountains K, with scrapers and brushes combined which parts are shown on an
enlarged scale in Figure 7. The fountains are upright vessels K having inclined
wings or vanes K' fastened on their inside, and a rotating vertical shaft, K²,
provided with vanes K³, inclined in an opposite direction from the vanes K¹. The
direction of the motion of the shaft K2 and vanes K³ is such that the paste by
their combined action is kept thoroughly stirred and pressed downward. The
rotary motion of the shaft K2 is imparted by an easily detachable clutch or
coupler K, from the upright shafts K³, propelled by pulleys K and endless cords K7,
receiving motion from the pulley Ks on the shaft H. A spout or arm K³, extends
from each to the paste fountain and is made flexible, so as to rise and fall to a
limited extent, and at the end terminates in an upright chamber or cylinder, K10,
from the bottom of which protrudes a brush, K", having a centre formed of
bristles K, between which paste is forced, and around which bristles are placed
steel scrapers K18, inclosed in a sheath of india-rubber K¼ The scrapers roughen
the exposed part of the leather and insure the penetration of the paste, and the
india-rubber covering or sheath prevents the paste splashing and wasting between
the scrapers. The brushes are rotated from the shafts K5 by means of cords and
pulleys.
The fountains K and arms K with their connected brushes and scrapers turn
about the axis of the shaft K³, so as to apply paste to the exposed portions of the
lining and quarters that protrude through the stencil J such motion being derived
from the cams K15 and K16 on the shaft H. The paste-fountains K are attached
by thumb-screws to the frame and are readily removed and attached so as to be
easily cleaned.
"
The molds or forms G, bearing vamps, are transferred from the table F2 by a
pair of elastic arms, L turning with a rock-shaft L', while the tables are stationary.
The motion of the rock-shaft L¹ is derived from the pinion L³, driven by a sector, L³,
moved by a cam L on the shaft H'. The pinion L³ is not rigidly secured to tlie
rock-shaft L' but it is connected by a clutch, Lº, having teeth bevelled in both
directions. This clutch has one member fastened to the rock-shaft L¹ and the
other member fastened to or formed on the side of the pinion L², against which it
is pressed by a spring L7 of sufficient tension to overcome all normal resistances in
transferring the form G and "vamp" to the form C and the "quarters When,
through accidents any undue resistance is encountered the pinion L³, bearing
against the bearing L³, turns without turning the rock-shaft L', but, instead, causes
it to move endwise, and by means of a lever, L³, liberates the spring H10 and
releases the toggles H, unclutches the driving pinion, and stops the machine.
When the vamp is applied to the quarters the guides or pins G³, being supported
by the springs G, yield and recede so as to permit close contact of vamps and
quarters and the form G clamps them firmly together by engaging the projections G¹
in the springs Cs on the forms C.
In the modified form of the machine, as shown in Figures 8, 9, and 10 instead of
the circular table B an endless band formed of plates hinged together in the
manner of the travelling platform of a "railway horse-car," is used to convey the
forms C and the intermittent cam-motion for progressively moving it is applied to
the reels or cylinders upon which it returns.
The operation of the machine is as follows; The quarters and inner lining, having
been previously sewed and turned, are placed in the forms C and successively
placed in the machine with the slides C' of the forms in the slots B* of the table B.
The bolts B³, engaging in the holes in the form C successively pass by the
intermittent motion of the table B to the stencils J and pasting devices, where they
receive a coat of paste on the parts exposed, and at the next step receive from the

page_text: arms La form G containing a vamp, which form G clasps by its projections G¹
upon the springs C of the form C, in which it is securely held. Upon farther
rotation of the table B the bolts B are retracted, and the forms containing the
parts pasted in exactly registered position are discharged by the springs B¹s upon
the table D. A counter or register may be added to record the work done by the
machine and also a second counter to record the number of times that the clutch HB
is liberated, so as to determine the amount of work produced by the machine.
