LASTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 435,888, dated September 2, 1890.

Application filed September 11, 1888. Serial No. 285,128. (No model.)

To an whmn it may concern.-

Be it known that I. SOLOMON B. ELLITHORP, a citizen of the United States, residing at \Vashington, District of Columbia, have invented a new and useful Improvementin Lastin g-Machin es, of which the followingis a specification.

My invention relates to an improvement in lastingmachines; and it consists in the peculiar construction and combination of devices, that will'he more fully set forth hereinafter, and particularly pointed out in the claims.

The object of my invention is to provide a cheap, simple, and'com pact machine by means of which shoes may be lasted with great rapidity and accuracy.

In the accompanying drawings, Figure is partly a top plan view and partly asectional view on the line 03a". of Fig. Fig. 2 is aside elevation of my improved lasting-machine. Fig. 3 is a vertical sectional view of the same. Fig. 4 is a detail vertical sectional view. Fig. 5 is a detail vertical sectional view illustrating a modified form of my invention. Fig. (i

is a detail perspective view of one of the side gatherers and the supporting-arm therefor.

Fig. 7 is a similar view of one pair of toe or heel gatherers and their supporting-arm. Fig. 8 is a similar view of one of the last-supports. Fig. 9 is a detail perspective view of one section of one of the side gatherers, one of the toe or heel gatherers, and the adjusting-link connecting the same.

A represents a tapered standard or pedestal, which is provided at its lower end with a base-plate B, that is adapted to be screwed or bolted to the floor. The upper end of the pedestal is screw-threaded, has an annular groove 0, and below the said groove 1s a flange D.

E represents a circular table, which is provided with a central circular opening F, of just sufficient diameter to clear the upper end of the pedestal and enable the table to bear upon and be supported by the flange D, whereby the table is pivoted on the pedestal and is adapted to revolve around the same.

G represents a vertical tubular standard, which has its lower end screwed to the upper end of the pedestal and provided with a flange II, that bears on the upper side of the table and retains the latter in the groove 0. The upper end of the said standard has a horizontal tubular arm I, which projects from one side thereof, and in the lower side of said arm is a slot K of suitable length.

The table E is provided with radial vertical slots L of suitable length, which are arranged at ninety degrees apart. Intersecting the center of each slot L is a slot M, which is arranged at right angles thereto. From the table, at the ends of each slot L, depends a pair of ears or brackets N,and depending from the ends of the slots M are similar brackets or ears 0.

P represents the shafts,which are j ournaled in the ears or brackets N, are provided with right and left hand screws R S, and each of the said shafts has at its outer end a handwheel T, and is provided at its center with a worm U.

V represents shafts,which are journaled in the ears or brackets 0. Each shaft-V has right and left hand screw-threads \V X at opposite ends, and is providedat its center with a worm-wheel Y, which engages the worm U of its companion shaft.

Z represents pairs of stamlards,which work in the slots L, one pair of said standards being in each slot, and have near their lower ends threaded openings, which are engaged by the right and left hand screw-threads of the shaft P. Each standard Z has a reduced neck portion A, which fits in the slot L, and has a pair of inverted-V-shaped transverse grooves B, 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 H represents curved toe and heel gatherers of the shape shown in Fig. 8, or of any other suitable shape, and one pair of said gatherers is pivoted on the head F of each arm E by a pair of screws 1. I

K represents standards,which are arranged in the slots M, and are similar in construction to the standard B, and have threaded openings near their lower ends,which are engaged by the right and left hand screw-threads 0f the shafts V,whereby the said standards may be moved toward or from 'each'other by rotating saidshafts V. On the spindles at the upper ends of the standards K are secured horizontal inwardly-extending arms L ,whioh are similar to the arms E, and are provided with set-screws M, by means of which they may be adjusted vertically on their support ing-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 center. a

0 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 P and acentral section R. The said sections are each provided with an opening S, and set-screws T pass through the said openings and engage threaded openings in the heads N, and thereby secure the gathering-plates on the said heads and adapt said gathering-plates to be adjusted laterally '7 and longitudinally, and thereby enable them to be contracted or extended to conform to a last of any size, thus rendering the gatheringplates serviceable with lasts of varying sizes. Each section P has its outer corner pivotally connected to a link U, the latter being provided with a longitudinal slot V. 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 setscrew V, which extends through the slot andengages 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 ofthe last with equal pressure, when the standards K and Z are caused to approach a common center 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 i'ecede 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 K simultaneously toward or from each other.

In each slot L is fitted a heel-support X and a toesupport Y 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 ooncaved, as at Z, and covered with a cushion A of soft leather, felt, or other suitable material.

B represents two right and left hand thread ed shafts, which engage threaded openings in the last-supports and connect the same together in pairs, as shown. At the center of each shaft B is a hand-wheel-C by means of'which the said shaft may be turned in order to adjust the toe and heel supports to ward or from each other, according to the length of the last which they are designed to support.

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-star;dards,and that each set of said gathering-standari-lsis provided with geared right and left hand threaded shafts and a hand-wheel, whereby they may be operated independen-tlyof theothers, thus in effect providing the table with four complete and independent mechanisms for supporting the lasts and applying the gat-he-rers thereto.

I will now proceed to describe the mechanism by means of which the upper is'stretched on the last. a

Near the base of the pede tal is fulcrumed a pedal-lever D one end of which projects through a vertical opening Win 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 pedallever. A bell-crank leverG is furlcrumed in the hollow arm I at its junction with the standard G, and one arm of the said hellcrank lever is pivotally connected to the up per end of the rod F H represents a horizontal bar, which is arranged in the hollow arm I, and is supported by a pair of links 1 The upper ends of said links are pivoted to said bar, and the lower ends of said links are pivoted ,on pins or bolts K that extend transversely across the lower side of the arm 'I. The inner end of the bar H is pivoted to the bellrcrank-lever G2 by a bolt or pin L which engages a slot M in said bell-crank lever.

N represents two'pairs of link-rods, which have their upper ends pivotally connected on opposite sides of the bar H and have [their lower ends pivoted to opposite sides ofa horizontally-disposed templct O near the ends thereof, as shown. The said templet is provided with radial slots, in which are inserted depending eyebolts P Adjusting-nuts R are screwed-to the upper ends of said'bolts and bear upon the upper side of the templet.

S represents a series of, clutches of suit- IIO able construction, which are suspended from the bolts P and are adapted to grip the edges of the shoeupper l), as shown in Fig. 3. The said clutches form the subject-matter of another pending application for Letters Patent of the United States, (Serial No. 285,127,) filed by me this day, and therefore do not need to be more particularly described in this specification. V

T 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 center of the horizontal arm I. A shaft U 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 T To theupper end of said shaft is secured a hand-wheel V 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 Fig. 3.

The operation of my invention is as follows: When the upperhas 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 F andthereby cause the bell-crank lever to move the bar H outward. Thelinks l are thereby caused to turn to an inclined position, and consequently cause the bar H to be lowered, and the link-rods N suspended from the said bar are thereby caused to lower the templet suffieientlyto enable the clutches to be engaged or attached to the edges of the upper. The screw-shaft U 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 pedallever and causes the rod F to descend and the bell-crank lever G to partly rotate and draw the bar l'l inward. The links I as they approach a vertical position elevate the bar H and consequently cause the templet to move upward,with the result that the clutches attached to the upper stretch the latter smoothly and firmly on the last. The operator then before releasing the pedal turns the hand-wheel T and causes the worm-gears and right and left hand threaded shafts to move the standards Z and K inward toward a common center, and thereby compress the side and toe and heel gathering plates over the bottom of the last and gather the leather of the upper 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 U 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 aqua-rter-revolution to another operative, 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 I illustrate a modified form of my invention, in which the pedal-lever is dispensed with and a crank-shaft (Z is journaled in the standard G and connected to the rod F. This crank-shaft has a crank-handle e, by means of which it may be very readily operated.

Having thus described my invention, I claim- I 1. In a lasting-machine, the combination of the tubular standard having a laterally-extending hollow arm provided with a slotin its under side, the revoluble table mounted upon said standard and having independent sets of gathering mechanisms, the templet suspended from a vertically-adjustable bar mounted upon links wit-hin'the hollow arin extending from the tubular standard, an opcrating-rod extending vertically through the latter, a bell-crank lever connecting said opcrating-rod with the vertically-adjustable bar carrying thetemplet, and a treadle connected with the lower end of the operati1.1g-rod,substantially as set forth.
