Improvements in and relating to Lasting Apparatus used in Manufac-
turing Boots and Shoes.
A communication from abroad by JAMES ALMON HILL, of 47, Rich Avenue, Mount
Vernon, in the State of New York, United States of America, Publisher.
I, ALFRED GEORGE BROOKES, of 55 & 56, Chancery Lane, in the County of
London, Chartered Patent Agent, do hereby declare the nature of this invention
to be as follows:-
--
This invention relates to the jack which receives and holds the last containing
the shoe, and also to the parts employed to position and actuate the crimping jaws.
The jack head is carried at the upper end of a revoluble spindle also free to be
slid vertically in its bearings, the lower end of the spindle being connected by a
ball ended link jointed to a foot treadle normally kept in its elevated position by a
strong spring, the strength of which may be readily adjusted by the operator.
The stand carrying the usual toe wiper may be slid accurately on the head to
occupy any desired position by means of a worm toothed pinion mounted in the
carriage and engaging worm teeth cut in the head, a worm on the carriage engag
ing the teeth of the pinion and turning it as required.
The carriage containing and supporting the last is made adjustable longitudinally
on the head. The said carriage has provided upon it an adjustable sleeve having
screw threads with which engage threads of the last holding pin provided with a
hand wheel whereby the operator may quickly and easily rotate the pin to put it at
the proper height and thereby put the sole of the last at the proper level or angle
that the toe wiper in its movement may be made to engage properly the upper
on lasts of varying shape or curvature, in fitting the last to the upper.
Prior to this invention the carriage having the last pin to receive the last has
been fixed on the head and all the adjustment to provide for difference in length
of last has been effected by moving the carriage containing the toe wiper. By
adjusting both carriages toward and from the spindle supporting the head the
operator can more readily position the last, and by sliding the carriage carrying
the toe wiper by the gear any desired position may be had for the said toe wiper..
The crimping jaws are pivotted upon a stud rising from a block free to slide in
a pivotted bed having sector teeth engaged by a worm on a shaft mounted in
a sliding stand carrying the said jaws, the rotation of said worm turning the
bed about its pivot to enable the crimping jaws to be put in the proper position
with relation to the last employed.
The shaft carrying the worm is extended through a bearing having a sleeve
surrounded by a hollow sleeve provided with a worm and hand nut, the worm
engaging the teeth of a worm toothed pinion sustained in said sliding stand and
engaging worm teeth formed on an arm of a rocking head, the lower end of said
stand having a tongue and groove connection with said arm,

page_text: By rotating the hollow sleeve the stand may be slid back and forth on the arm
of the head according to the length of the last.
The block carrying the crimping jaws is slid in the pivotted bed, and the jaws
are closed as the block is moved in one direction, and opened when moved in
the opposite direction by or through a hand lever, tubular at its inner end
and fitted over a stud in said block, said lever having at its lower end an arm
which is extended through an opening in the block and connected by a link to a
stud of the bed.
}
The tubular part of the lever also has keyed upon it a lever to which is pivotted
links in turn jointed to the inner ends of the crimping jaws. As the hand
lever is turned about the fixed stud of the block, the arm of the lever jointed to
one end of the link held at its other end by the bed results in sliding the block
in the bed in one or the other direction according to the direction in which the
lever is turned.
When turned in one direction the block is slid toward the last, and at the
same time the jaws are gradually closed to crimp closely the leather overturned
on the sole.
Usually in lasting machines there is a separate toe crimping plate for each size
of last, and when a last of a different size was to be used the machine has had
to be stopped and the crimping jaws and plate have been removed in order that
a plate of the proper shape might be put on the machine, but herein there is
provided one plate with a series of recesses of different sizes to cooperate with
different sizes or shapes of last, and when a different last is to be used it is only
necessary to lift a pin and turn the toe crimping plate into position to bring into
operative position the notch of the proper size.
The following indicates a convenient form of apparatus for carrying out the
invention:-
A column, adapted to stand on the floor, has an extended arm provided with a
bearing, and a second extended arm provided with a step for a spindle extended
through said bearing and maintained in proper position in said bearing by a
suitable collar secured to said spindle.
The spindle above the bearing has fixed upon it the hub of a rocking head having
two arms carrying respectively the heel and toe lasting devices.
These arms occupy a position nearly at right angles one to the other, and the
head is movable with the spindle, the head having two working positions, one when
the heel is being lasted, and the other when the toe is being lasted, and at such
time either of such arms will stand substantially in line with the arm referred to
as extended from the column.
A stud rises from the last named arm and serves as a stop to determine the
position of the head during the time that the crimping jaws are being moved
forward over the toe of the upper on the last.
The arms referred to as relatively at right angles are each grooved to receive
tongues extended from suitable carriages carrying the toe lasting devices, and said
arms each have a series of rack teeth in their upper sides.
One such arm has a depending stud on which is pivotted a locking device say
a lever having its end extended upwardly at the inner side of the carriage upon
which is mounted the heel lasting devices, said locking device having an arm
extended horizontally under the previously named arm and notched to embrace the
stud in its working position, the locking device engaging the stud and holding the
said arm in the position required while operating the heel lasting devices by a
right hand pull on the hand lever a suitable spring keeping the locking device
normally in its position to engage readily the stud whenever the said arm is
swung into position parallel with the top of the extension arm.
The underside of the second right angled arm is provided with a depending
lug which, as this second arm is put into position parallel with the extension arm
meets the stop and acts as an abutment while the operator, by a right hand pull
on the hand lever actuates the toe lasting devices.

page_text: The carriages carrying respectively the heel lasting and the toe lasting devices
are substantially alike, so but one need be specifically described.
*
Each arm relatively right angled" about which the ears at the lower ends
of these carriages are fitted to slide, has a like series of teeth.
Each carriage has a worm toothed gear engaged by a suitable worm on a hollow
shaft having a hand wheel said holiow shait being sustained on a sleeve which
constitutes the bearing for a shait having a worm and a hand wheel.
Each of the worms engages worm teeth at the end of a like sector extended from
each of two like beds pivotted between upright ears forming parts of said carriages.
By rotating the shaft the bed may be turned about its pivots to put the acting
ends of either of the crimping jaws used to crimp the toe and heel at the proper
angle with relation to the toe and heel end of the last, that said jaws when
moved over either the toe or heel may contact properly therewith.
The rotation of the hollow shaft and its worm working through the gear adjusts
the carriage containing the heel or toe lasting devices longitudinally toward and.
from the last, and this may be done quickly, the two hand wheels being arranged
closely together so that the operator with his hand in one position may readily
adjust either the bed or the carriage into any desired position.
Each bed contains a block having through it an opening and at one side of said
opening the block has rising from it a stud.
Said stud receives the tubular end of one of two hand levers the said tubular
part having a spline to enter a groove in a lever having at its opposite ends
suitable holes.
These holes receive suitable pins upon which are pivotted links in turn
jointed to the rear ends of the heel crimping jaws, said Jaws being each mounted
to turn about a suitable stud entering a hole in the block said stud having a cross
hole near its upper end in which is inserted a pin, said pin being locked in working
position.
The front ends of the block may be provided with a surface of leather or india
rubber to prevent the block from marring the leather of the upper, said blocks
holding the upper more firmly than would metal alone, while the crimping plates
act to lay the upper over upon the inner sole.
The lower end of the sleeve of each of the hand levers has a like arm which is
extended downwardly through the slot the lower end of said arm entering a hole in
a link, the opposite end of said link being pivotted upon a stud, anchored in the
bed.
With this construction, assuming that the crimping jaws are in their inoperative
position, it will be readily understood that by taking hold of either of the handles
in the right hand and pulling the same toward the front of the machine the
position occupied by the operator, that the rotation of either handle will cause
the arm acting in the link to slide the block in the desired direction near said
jaws, the block taking with it the pair of crimping jaws, and as the hand lever
is turned the lever connected therewith acting through the links closes the open
front ends of the crimping jaws, the action of the hand levers causing the crimping
jaws to slide up to meet the upper, either at the heel or toe, whichever one is
being lasted and gradually close the jaws, folding and crimping the upper inwardly
and laying the same over upon the bottom of the last in the usual method of toe
and heel lasting.
Between the blocks and the underside of the crimping jaws is applied a crimping
plate. This plate has a central hole which fits the pin and the plate, bas a series
of notches of different sizes, according to the toes of the different lasts containing
the uppers to be lasted.
The plate has a series of locking holes any one of which may be entered by a
suitable removable pin. When the pin is removed the operator may readily turn
the plate about that portion thereof containing a notch of the proper size at the
front end of the block.
This notched crimping plate meets the upper at the extreme toe of the last

page_text: and pushes it over upon the inner sole of the last just before the crimping jaws
are closed to wipe over from the opposite sides of the toe inwardly upon the inner
sole lying on the last.
Heretofore in machines of the class herein described there has been a separate
crimping plate for each size of last used, and the jaws had to be removed in order
to take off a crimping plate and substitute another of the proper size for it.
The jack for holding the shoe consists essentially of a head having a depending
sleeve, which is fitted over the end of a spindle and secured thereto by a set
screw.
The spindle enters suitable bearings carried by the column and the lower end
of the spindle is provided with a socket having screw threads.
The socket receives the ball shaped end of a link, jointed by a pivot at its lower
end to a treadle pivotted on the column, said treadle having connected with it one
end of a spring, the upper end of said spring being connected to a plate having a
suitable screw thread which is entered by the shank of a screw having a suitable
hand nut readily accessible by the operator so that by turning said screw the
stress of the spring may be increased or diminished to suit the requirements
of the operator or the work to be done.
The threaded end of the socket in the spindle receives a suitable split union.
The head has at one side a series of holes, and also a series of rack teeth.
The head is suitably shaped to be embraced by two carriages, one carriage
sustaining a suitable last pin while the other carriage sustains a toe wiper sub-
stantially of well known construction.
The stand is made adjustable horizontally upon the head and it may be locked
in any of its several adjusted positions by a suitable stud passed through a hole
in said stand and entering one of the holes.
4
The stand has a pivot upon which is mounted a lever, shaped at its lower end to
represent a toothed sector, the teeth of said sector being engaged by a worm on a
suitable shaft having a hand wheel by which to operate it to turn the lever about
the pivot.
The upper end of the lever is bored and threaded to receive the threaded shank
of a last pin, it being provided with a suitable hand wheel which may be readily
engaged by the operator to raise and lower the last pin to thereby quickly gain
for the heel of the last the proper position with relation to a horizontal line, and at
the same time the operator may tip the lever according to the requirements of the
hole in the last, the said hole some times being more or less worn and requiring
more or less adjustment of the last pin about the pivot in order that the upper
end of the pin may fit on both sides of the hole.
The carriage at one side has a suitable stud which receives over it a worm toothed
pinion, which is engaged by worm teeth of a suitable screw, also mounted in said
carriage, the rotation of said screw carrying the worm turning the pinion, causing
its teeth in engagement with the rack teeth of the head to adjust the carriage
horizontally and longitudinally of the head in order to properly position the toe
wiper so that it will contact with the shoe into the position desired during which
operation the edge of the toe wiper, preferably of stiff leather, in contact with the
upper on the last stretches the upper in the direction of its length toward the toe,
the toe wiper stopping in the elevated position required and holding the upper
firmly against the toe in position to enable the crimping plate and the crimping
jaws to approach the upper so held and lay it over the inner sole.
Heretofore a carriage carrying a toe wiper has been adjusted upon the head
carrying it, but so far as I am aware a carriage carrying the last pin has not been
50 adjusted, and great advantages result from adjusting both of these carriages, as
thereby a greater range of sizes of lasts may be readily applied to and held by the
jack.
In the improved machine the upper does not contact with the hollow part of the
top of the last, so when the toe wiper is in position the operator engages the upper
by usual pinchers and draws it in a direction to strain the upper across the last,

page_text: and the drawn upper is then tacked to the inner sole. This drawing fits the upper
snugly to the entire top of the last. After this and after having laid the edge of
the upper immediately at the toe over upon the inner sole and inserted a tack
temporarily, the crimping jaws are operated to complete the crimping and laying
of the toe or heel end of the upper on over the last, the jaws may be then in
position to be operated, and the upper laid the operator secures the same by
suitable tacks.
The upward position of the spindle and the jack is determined by an adjustable
collar secured to the spindle by a suitable set screw.

Improvements in and relating to Lasting Apparatus used in Mauufac-
turing Boots and Shoes.
A communication from abroad by JAMES ALMON HILL, of 47, Rich Avenue, Mount
Vernon, in the State of New York, United States of America, Publisher.
I, ALFRED GEORGE BROOKES, of 55 & 56, Chancery Lane, in the County of
London, Chartered Patent Agent, 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:-
The invention to be herein described relates to the jack which receives and
holds the last containing the shoe to be lasted, and also to the parts employed
to position and actuate the crimping jaws.
The jack head is carried at the upper end of a revoluble spindle, also free to
be slid vertically in its bearings, the lower end of the spindle being connected
with a foot treadle by a ball ended link jointed to said foot treadle, which is
normally kept in its elevated position by a strong spring. The strength of the
spring may be readily adjusted by the operator.
The stand carrying the usual toe wiper may be slid accurately on the head
to occupy any desired position by means of a worm toothed pinion mounted in
the carriage and engaging worm teeth cut in the head, a worm on the carriage
engaging the teeth of the pinion and turning it as required.
The carriage containing and supporting the last is made slidable longitudinally
on the head, the base of said carriage being fitted to slide with relation to a
guideway of the jack head.
Said carriage is provided with an adjustable sleeve having screw threads,
with which engage threads of a last holding pin having a hand wheel.
By means of this wheel the operator may quickly and easily rotate the pin to
put it at the proper height, and thereby put the sole of the last at the proper
level or angle, that the toe wiper in its movements may be made to engage
properly the upper on lasts of varying shape or curvature, in fitting the last to
the upper.
The body of the last supporting carriage, which contains the sleeve referred
to and is movably supported by the jack head, may and preferably will be made
in two parts: a foot part and a body part.
The body part contains a pivot for the sleeve and has a segmental toothed
foot, free to be moved in a guide-way in the foot part of the carriage.

page_text: The teeth of said toothed foot are of proper shape to be engaged by the teeth
of a worm on a shaft sustained by the carriage referred to.
By rotating said worm the body part of the carriage, on which is pivotted the
sleeve carrying the last pin, may be tipped in a vertical plane transverse to the
length of the last. Thus the last pin of the jack may be suitably inclined with
relation to a perpendicular line, in order that said pin may enter the "base" of the
last and correctly position the bottom of the last, even through the "base"
socket should not be made exactly vertical or should have become enlarged
by use.
or
The sleeve carrying the last pin may also be tipped to incline the pin toward
cr from the toe or heel crimping jaws or devices.
The crimping jaws are pivoted upon a stud rising from a block which is free
to slide in a pivoted bed having sector teeth engaged by a worm on a shaft, said
shaft being mounted in a sliding stand carrying the said jaws. The rotation
of said worm turns the bed about its pivot, to enable the crimping jaws to be
put in the proper position with relation to the last employed.
The shaft carrying the worm is extended through a bearing having a sleeve
surrounded by a hollow sleeve, which is provided with a worm and hand nut.
The worm engages the teeth of a worm toothed pinion sustained in said sliding
stand, and said pinion engages worm teeth formed on an aim of a rocking head,
the lower end of said stand having a tongue and groove connection with said
arm.
By rotating the hollow sleeve the stand may be slid back and forth on the
arm of the head according to the length of the last.
The block carrying the crimping jaws is slid in the pivoted bed, and the jaws
are closed as the block is moved in one direction, and opened when the block is
moved in the opposite direction by or through a hand lever, which is tubular
at its inner end and fitted over a stud in said block.
Said lever has at its lower end an arm which is extended through an opening
in the block and connected by a link to a stud of the bed.
The tubular part of the lever also has keyed upon it another lever, to which is
pivoted links jointed in turn to the inner ends of the crimping jaws.
As the hand lever is turned about the fixed stud of the block, the arm of said
lever, jointed to one end of the link which is held at its other end by the bed,
results in sliding the block in the bed in one or the other direction, according
to the direction in which the lever is turned.
When the hand lever is turned in a direction to slide the block toward the
last, the jaws moving with the block are gradually closed to act upon the leather
of the upper and overturn it on the inner sole.
Usually in lasting machines there is a separate toe crimping plate for each
size of last, and when a last of a different size is to be used, the machine has to
be stopped and the crimping jaws have to be removed, in order that a crimping
plate of the proper shape may be put on the machine.
Herein I have obviated the change of crimping plate by providing one plate
with a series of recesses of different sizes to cooperate with different sizes or
shapes of last.
When a different last is to be used I have only to lift a pin and turn the toe
crimping plate into position to bring into operative position the notch of the
proper size.
Fig. 1 in side elevation, represents a lasting machine containing the invention
to be herein described, the last with the upper and toe wiper being shown as
having been adjusted in proper position, preparatory to actuating the toe wiper
for fitting the upper to the last.
Fig. 2 is a top or plan view of the machine in a different position from that
represented in Fig. 1, the last being removed, and the heel and toe lasting
devices being in their inoperative positions; the head carrying said devices being

Fig. 17 is an enlarged sectional detail in the line, Fig. 15.
Fig. 18 is a section in the line 6, Fig. 15.
The column A adapted to stand on the floor, has an extended arm A¹ provided
with a bearing A2, and a second extended arm A³ provided with a step A+ for a
spindle A³, which is extended through the bearing A³ and is maintained in proper
position in said step by a suitable collar A6 secured to said spindle by a set
screw A.
The spindle, above the bearing A2, see Fig. 2, has fixed upon it, by a suitable
set screw A8, the hub of a rocking head A having two arms A10, A1, said arms
carrying respectively the heel and toe lasting devices to be described.
These arms occupy a position nearly at right angles one to the other, and the
head is movable with the spindle A5, the head having two working or operative
positions, one when the heel is being lasted, and the other when the toe is being
lasted, and at such time either of the arms A10 and A" will stand substantially
in line with the arm A¹.
Fig. 2 shows the head in an inoperative position, chiefly to illustrate a stud B
rising from the arm A¹ and serving as a stop to determine the position of the
head during the time that the crimping jaws are being moved forward over the
toe of the upper on the last.
The arms A10, A1 are each grooved at their sides, as at a*, as represented best
by the arm Ao in Fig. 11, to receive a tongue as a extended from suitable
carriages to be described, which carry the toe and heel crimping jaws, and said
arms each have a series of rack teeth a¹ at their upper sides.
The arm A10 has a depending stud on which is pivoted a locking device n³,
shown as a lever having its end extended upwardly at the inner side of the car-
riage B, upon which is mounted the heel crimping jaws.
Said locking device has an arm a¹, see Fig. 12, extended horizontally under
the arm A, and notched to embrace the stud B, represented in Fig. 12 as in

page_text: section, in its working position. The locking device engages the stud and holds
the arm A10 in the position required while operating the heel crimping jaws by
a right hand pull on the hand lever b', to be described, and a suitable spring a
keeps the locking device normally in its position to engage readily the stud B
whenever the arm A10 is swung into position parallel with the top of the exten-
sion A¹.
The underside of the arm A¹ is provided, see Figs. 1 and 17, with a depending
lug carried by a positioning device which, as the arm A" is put into posi-
tion parallel with the arm A, meets the stop B and acts as an abutment while
the operator, by a right hand pull on the hand lever b', actuates the toe lasting
devices.
The carriages B₁ and D' carrying respectively the heel crimping jaws and
the toe lasting device are substantially alike, therefore only one of them need
be specifically described.
Each of the arms A10 and A", on which these carriages are fitted to slide,
has a like series of teeth a¹.
Each carriage has, see the carriage D¹, Fig. 3, a worm toothed gear as D³,
which is engaged by a suitable worm D³ on a hollow shaft D which has a
hand wheel D5, said hollow shaft being sustained on a sleeve D6, see Fig. 9,
which constitutes the bearing for a shaft D7 having a worm D, and a hand
wheel D⁹.
Each of the worms DB engages worm teeth at the end of a like sector D¹º,
extended from each of the two like beds D¹³, pivoted at 6 see Fig. 15 between
upright ears forming parts of said carriages.
By rotating the shaft D the bed may be turned about its pivots to put the
acting ends of either of the crimping jaws 65, used to crimp the toe and heel,
at the proper angle with relation to the toe and heel end of the last, that said
jaws when moved over either the toe or heel may contact properly therewith.
The rotation of the hollow shaft D4 and its worm working through the gear D3
adjusts the carriage containing the heel or toe lasting devices longitudinally
toward and from the last, and this may be done quickly, the two hand wheels D5
and D being arranged closely together so that the operator with his hand in
one position can readily adjust either the bed or the carriage into any desired
position.
Each bed D¹ contains a sliding block E, having made through it from top
to bottom an opening E', see Figs. 7 and 8, and at one side of said opening the
block has rising from it a stud e.
The stud e receives upon it the tubular end of one of the hand levers b₁, the
said tubular part having an exterior spline e to enter a groove e³, see Fig. 6,
in a lever e³, having at its opposite ends suitable holes as e, e
These holes receive suitable pins upon which are pivoted suitable like links e,
and e, in turn jointed to the rear ends of the crimping jaws 65, 66, said jaws,
arranged in pairs, being mounted to turn about a suitable stud, as es, entering a
hole in the block E, said stud having a cross hole near its upper end in which
is inserted a pin e, said pin being locked in working position by a set screw e10.
The front ends of the block E may be provided with a surface of leather or
india rubber as at e¹2 to prevent the block from marring the leather of the upper,
said blocks holding the upper more firmly than would metal alone, while the
crimping plates act to lay the upper over upon the inner sole.
The lower end of the sleeve of each of the hand levers b', see Fig. 4, has a like
arm, as f, which is extended downwardly through the slot E, the lower end
of said arm entering a hole in a link f, the opposite end of said link being
pivoted upon a stud f2, anchored in the bed D12, see Fig. 3, and Fig. 4 shows
the stud in section.
With this construction, assuming, see Figs. 2 and 3, that the crimping jaws
are in their inoperative positions, it will be readily understood that by taking
hold of either of the handles b¹ by the right hand and pulling the same toward

page_text: the front of the machine, the position occupied by the operator, the rotation of
either handle will cause the arm f, acting in the link, to slide the block E in
the direction of the arrows near said jaws in Figs. 2 and 3, the block taking
with it the pair of crimping jaws.
As the hand lever is turned the lever connected therewith, acting through
the links e, e7, closes the open front ends of the crimping jaws, the action of
the hand levers causing the crimping jaws to slide up to meet the upper, either
at the heel or toe, whichever one is being lasted, the jaws being gradually
closed, and folding and crimping the upper inwardly, laying the same over upon
the bottom of the last or the inner sole therein, in the usual method of toe and
heel lasting.
Between the blocks E and the underside of the crimping jaws I have applied
a crimping plate g, shown detached in Fig. 5. This plate has a central hole g¹,
which fits the pin e8, and the plate has a series of notches g², g³, g, g³, of different
sizes, according to the toes of the different lasts containing the uppers to be
lasted:
The plate has a series of locking holes y, any one of which may be entered
by a suitable removable pin g. When the pin is removed the operator may
readily turn the plate g, bringing that portion of the plate containing the notch
of the proper size at the front end of the block E.
This notched crimping plate meets the upper at the extreme toe of the last
and pushes it over upon the inner sole of the last just before the crimping jaws
are closed to wipe the upper over from the opposite sides of the toe inwardly
upon the inner sole lying on the last.
Heretofore in machines of the class herein described there has been a separate
crimping plate for each size of last used, and the jaws had to be removed in
order to take off a crimping plate and substitute another of the proper size for it.
The jack for holding the shoe consists essentially of a head H, having a depend-
ing sleeve which is fitted over the end of a spindle H2, and secured thereto by
a set screw H³.
The spindle enters suitable bearings as H4, carried by the column, and the
lower end of the spindle is provided with a socket H³ having screw threads, see
Fig. 10.
The socket receives the ball shaped end of a link H³, jointed by a pivot He at
its lower end to a treadle H7, pivoted at H8 on the column. Said treadle has
connected with it one end of a spring H⁹, the upper end of which is connected
to a plate H10. This plate has a suitable screw thread which is entered by the
shank of a screw H12 having a suitable hand nut readily accessible by the operator,
so that by turning said screw the stress of the spring may be increased or
diminished to suit the requirements of the operator or the work to be done.
The threaded end of the socket in the spindle Hª receives a suitable split
union h, see Fig. 10.
The head is suitably shaped to be embraced by two carriages 3 and 4, the
carriage h³ sustaining a suitable last pin to be described, while the carriage h
sustains a toe wiper h of well known construction, so that a detailed description
of the toe wiping mechanism is not herein necessary.
The head has at one side a series of holes h¹, any one of which may receive
a locking stud 6, and at its opposite side said head also has a series of rack
teeth h9.
The base of the stand h³ is grooved to be embraced and readjusted horizontally
upon the head H, see Fig. 18, and it may be locked in any of its several adjusted
positions by a suitable stud, as he, passed through a hole in said stand and enter-
ing one of the holes h¹.
The foot part of the carriage h³, at a point above the level of the head H, is
provided with a transverse way or groove h7, which receives the segmental
toothed base 8 of the body part of the carriage.
The foot part of the carriage h³ also has a suitable stud or pin 410, on which

page_text: is mounted a hand operated sleeve h¹ provided with a worm h¹³, which engages
the worm teeth of the base h³.
The rotation of the worm causes the last pin A, the shank of which enters
a sleeve h¹5 pivoted at h¹ on the body part to occupy a position more or less
inclined to a line drawn longitudinally through the head H, to thereby adapt
the last pin to any peculiarity or malformation of the hole in the last used.
The last pin is threaded at the end entering the sleeve, and the pin has a
hand wheel h", which may be. engaged by the operator to put the heel end of
the last at the proper level according to the shape of the last and the depth of
the same.
The lower end of the sleeve 15 has a toothed sector h¹, see Fig. 15, which is
engaged by a worm 20 on a short worm shaft. The rotation of the worm 20
tips the sleeve and pin in the direction of the length of the head H.
The tipping of the sleeve on its pivot 16 also enables the last pin to properly bind
in the hole in the last.
The carriage hat one side has a suitable stud, as m, which receives over it
a worm toothed pinion m', which latter is engaged by worm teeth of a suitable
worm m² (Fig. 2) also mounted in said carriage.
The rotation of said worm turns the pinion and causes its teeth, in engagement
with the rack teeth h² of the head, to adjust the carriage h horizontally and longi-
tudinally of the head in order to place the toe wiper in the position in which it
will contact with the shoe at the desired point. Or, as represented in Fig. 1,
the toe wiper is thereafter actuated or moved into the position Figs. 13 and 14,
during which operation its edge, the toe wiper being preferably of stiff leather,-
by contact with the upper on the last, stretches the upper in the direction of its
length toward the toe. The toe wiper stops in the elevated position shown in
Figs. 13 and 14, and holds the upper firmly against the toe in position to enable
the crimping plate and the crimping jaws to approach the upper so held and lay it
over the inner sole w represented in Fig. 14 as lying on the last w¹.
Great advantages result from adjusting both the carriage carrying the toe
wiper and the carriage carrying the last pin, as thereby a greater range of sizes
of lasts may be readily applied to and held by the jack.
Referring to Fig. 14, it will be seen that the upper at x does not contact with
the hollow part at 2 of the top of the last w¹.
When the toe wiper is in the position Figs. 13 and 14 the operator engages
the upper by usual pinchers and draws it in a direction to strain the upper across
the last, and the drawn upper is then tacked to the inner sole. This drawing fits
the upper snugly to the entire top of the last. After this and after having laid
the edge of the upper immediately at the toe over upon the inner sole and inserted
a tack temporarily, the crimping jaws are operated to complete the crimping and
laying of the toe end of the upper over the inner sole on the last, and the upper
laid, the operator secures the same by suitable tacks.
The upward position of the spindle H2 and the jack is determined by an adjust-
able collar r, secured to said spindle by a suitable set screw rl.
The arm A is provided with a device a³ which engages the stud B, to lock that
arm in its operative position.
I have also provided the arm A, carrying the jaws for crimping the toe, with a
device by which said arm and said crimping jaws may be accurately positioned.
This device consists of a screw 72, represented as provided with right and left
threads, one of said threads engaging screw threads in a box suitably bolted to
the arm A. The screw threads of opposite pitch enter a threaded sleeve con-
nected with a positioning device 5. Said device has a hook which, when the
arm A¹¹ and toe crimping plates are in position, may be made to engage the stud B
referred to.
The acting end of the positioning device may be moved rapidly in one or
other direction by turning the screw shaft r², which slides the sleeve r.

page_text: To keep the end of the positioning device in engagement with the stud B,
I have employed a spring 7.
To disengage said positioning device from said stud when it is desired to turn
the arms A, A", the arm of the positioning device will be turned in the
direction of the arrow near its upper end in Fig. 15.
This positioning device has a cam surface, see Fig. 15, which, when the
positioning device is turned to disengage the stud B, acts to lift the end of a
locking device pivoted at 10, removing said locking device from between two
pins, which project from that end of the head H which supports the toe wiper.
The spring H is sometimes so set that it will lift the rod H2 with very consider-
able force when the operator removes his foot from the treadle H7.
This spring has to be checked in its upward movement, and to provide for the
check the rod has secured to it the collar r. To avoid shock and wear of both the
clamp and framework, I have chambered the underside of the ear H', letting the
collar enter it with a piston fit, thereby making a dash-pot of the ear H, the
collar cushioning on the air in the dash-pot.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is: -
