page_text: engaged by the right and left hand screw-threads of the shaft P. Each standard Z
has a reduced neck portion A¹ which fits in the slot L and has a pair of inverted
V-shaped transverse grooves B¹ which engage similarly shaped guide flanges C
with which the table is provided and which are arranged on opposite sides of and
parallel with the slots L. The upper ends of the standards Z are reduced to form
vertical spindles D¹.
E¹ represents arms, which have openings in their outer ends to receive the spindle D¹
and have their inner ends enlarged to form heads F¹. Set screws GI engage
threaded openings in the outer ends of said arms and are adapted to impinge on
the spindles D in order to clamp the arms E¹ to the standards at any desired vertical
adjustment.
H' represents curved toe and heel gatherers of the shape shown in Fig. 7 or of any
other suitable shape and one pair of said gatherers is pivoted on the head F¹ of each
arm E¹ by a pair of screws 11.
Krepresents standards which are arranged in the slots M and are similar in
construction to the standards Z and have threaded openings near their lower ends,
which are engaged by the right and left hand screw-threads of the shafts V whereby
the said standards may be moved toward or from each other by rotating said shafts V.
On the spindles at the upper ends of the standards K' are secured horizontal inwardly
extending arms L' which are similar to the arms E' and are provided with set-
screws M₁ by means of which they may be adjusted vertically on their supporting
standards. The inner ends of the arms L' are widened to form heads N' which
correspond in shape with the sides of the last and have their upper sides waved or
curved as shown in Fig. 6. Each head is further provided with vertical threaded
openings near its ends and at its centre.
O¹ represents side gathering plates which are adapted to fit snugly on the upper
sides of the heads N and are each formed of two end sections Pr and a central
section R'. The said sections are each provided with an opening S¹ and set-screws T¹
pass through the said openings and engage threaded openings in the heads N¹ and
thereby secure the gathering plates on the said heads and adapt said gathering plates
to be adjusted laterally and longitudinally and thereby enable them to be contracted
or extended to conform to a last of any size, thus rendering the gathering plates
serviceable with lasts of varying sizes. Each section P¹ has its outer corner pivotally
connected to a link U₁, the latter being provided with a longitudinal slot V₁. The
said slotted portion of the link bears upon the outer end of the adjacent toe or
heel gatherer and is secured thereto by means of a set-screw W¹ which extends
through the slot and engages a threaded opening in said toe or heel gatherer.
By this means the toe and heel gatherers are connected to the side gatherers so
that the entire set of gatherers is adapted to work in unison and to be forced
against all sides of the last with equal pressure when the standards K' and Z are
caused to approach a common centre by rotating one of the hand-wheels T.
It will be understood from the foregoing that when one of said hand-wheels is
rotated it turns the shaft P and causes the standards Z to approach or recede from
each other according to the direction in which the wheel is turned and that the worm
gear which connects each shaft P to its companion shaft V causes the screw-threads
of said shaft V to move the standards K₁ simultaneously towards or from each
other.
In each slot L is fitted a heel support X' and a toe support Y₁ for the last, said
heel and toe supports are similar in construction to the standards Z and K-each
heel support has a spindle at its upper end adapted to fit in a socket in the heel of
the last a, and each toe support has its upper end concaved as at Z' and covered with
a-cushion A³ of soft leather felt, or other suitable material.
B² represents two right and left hand threaded shafts which engage threaded
openings in the last supports and connect the same together in pairs as shown. At
the centre of each shaft B2 is a hand-wheel C² by means of which the said shaft
may be turned in order to adjust the toe and heel supports towards or from each
other according to the length of the last which they are designed to support.

page_text: From the foregoing description and by reference to the accompanying drawings,
it will be understood that the circular revoluble table is provided with four sets of
last supports and gathering standards and that each set of said gathering standards is
provided with geared right and left hand threaded shafts and a hand-wheel, whereby
they may be operated independently of the others, thus in effect providing the table
with four complete and independent mechanisms for supporting the lasts and applying
the gatherers thereto.
I will now proceed to describe the mechanism by means of which the upper is
stretched on the last.
Near the base of the pedestal is fulcrumed a pedal lever D³ one end of which
projects through a vertical opening E2 in one side of the pedestal. F represents a
vertically movable rod, which extends through the pedestal and through the vertical
standard G and has its lower end pivotally connected to the pedal lever. A bell
crank lever G2 is fulcrumed in the hollow arm I at its junction with the standard G..
and one arm of the said bell crank lever is pivotally connected to the upper end of the
rod F2.
H2 represents a horizontal bar which is arranged in the hollow arm I and is
supported by a pair of links 12. The upper ends of said links are pivoted to said bar
and the lower ends of said links are pivoted on pins or bolts K³ that extend
transversely across the lower side of the arm I. The inner end of the bar H2 is
pivoted to the bell crank lever G2 by a bolt or pin L² which engages a slot M² in said
bell crank lever.
N2 represents two pairs of link rods which have their upper ends pivotally connected
on opposite sides of the bar H2 and have their lower ends pivoted to opposite sides of
a horizontally disposed templet 02 near the ends thereof, as shown.
The said templet is provided with radial slots in which are inserted depending eye-
bolts P. Adjusting nuts R2 are screwed to the upper ends of said bolts and bear
upon the upper side of the templet. S² represents a series of clutches of suitable con-
struction which are suspended from the bolts P2 and are adapted to grip the edges of
the shoe upper b as shown in Fig. 3. T2 represents a horizontal arm which is secured
to the standard G and projects from one side thereof and is arranged directly below
and in line with the centre of the horizontal arm I. A shaft U2 has its upper end
guided in an opening in the upper side of the arm I and has its lower end threaded
and passed through a threaded opening in the arm T2. To the upper end of said
shaft is secured a hand-wheel V2 by means of which it may be rotated and thereby
caused to move upward or to descend. The function of this screw-shaft is to bear
upon the ball of the last and thereby maintain the same firmly in position on the last
supports as shown in dotted lines in Fig. 3.
The operation of my invention is as follows:-
When the upper has been placed on the last, the latter is arranged on the last
supports, the operator causes the pedal lever to be raised and elevate the rod I" and
thereby cause the bell crank lever to move the bar H2 outward, the links I are
thereby caused to turn to an inclined position and consequently cause the bar H² to
be lowered and the link rods N2 suspended from the said bar are thereby caused to
lower the templet sufficiently to enable the clutches to be engaged or attached to the
edges of the upper.
The screw-shaft U2 is then turned down and caused to bear lightly on the ball of
the last to prevent the latter from rising from its supports and the operator then
depresses the pedal lever and causes the rod F2 to descend and the bell crank lever. G²
to partly rotate and draw the bar H2 inward. The links I as they approach a vertical
position, elevate the bar H2 and consequently cause the templet to move upward with
the result that the clutches attached to the upper stretch the latter smoothly and firmnly
on the last.
The operator then, before releasing the pedal, turns the hand-wheel T and causes
the worm gears, right and left hand threaded shafts to move the standards Zan! K¹
inward toward a common centre and thereby compress the side and toe and heel
gathering plates over the bottom of the last and gather the leather of the upper

page_text: smoothly and firmly thereon and over the insole which has been previously placed on
the last. The pedal is then released to relax the tension on the templet, the clutches
are disengaged from the upper, the screw 2 released from the last, and the table
moved to the right to a quarter revolution and caused to carry the lasted shoe to
another operator who tacks the same. After this, the table is again moved through a
quarter revolution to another operator who takes off the lasted shoe from the
machine.
By reference to Fig. 1, the positions of the persons who operate the machine will be
readily understood.
The person stationed at the point 1 applies the last to the machine; the person
stationed at the point 2 lasts the shoe by applying the gatherers and operating the
templet as before described; the person stationed at the point 3 tacks the upper to
the insole of the lasted shoe and the person stationed at the point 4 removes the shoe
from the machine.
Thus four shoes are continuously operated upon when the machine is running at its
full capacity and hence the machine is adapted to last a great number of shoes in a
comparatively short time.
It will be understood that skilled workmen need not be employed in lasting shoes
when this machine is used as the work may be performed very readily by boys or
girls. In Fig. 5 1 illustrate a modified form of my invention in which the pedal
lever is dispensed with and a crank shaft d, is journaled in the standard G and con-
nected to the rod F³. This crank shaft has a crank handle e, by means of which it
may be very readily operated.
