LASTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 458,000, dated August 18, 1891.

Application filed February 10, 1890. Serial No. 339,803. (No model.)

T all whom it may concern:

Be it known that we, GORDON MCKAY, of Newport, Newport county, and State of Rhode Island, and HADLEY P..FAIRFIELD, of Medford, Middlesex county, and State of Massachusetts, have invented an Improvement in Lasting-Machines, of which the following description, in connection with the accompanying drawings,` is a specification, like letters ro and figures on the drawings representing like parts.

This invention is an improvement more particularly on that class of machines represented in United States Patent No. 250,450, but some I5 of the features of invention are applicable to other forms of lasting-machines.

In the machine herein to be described the pinchers or pullers are mounted in pairs upon eveners shown as pivoted bars mounted upon 2o spring-supported slide-bars, so that the pinchers or pullers of each pair may be made to pull and stretch to any desired extent the particular part of the upper engaged thereby irrespective of the strain put upon other parts z 5 of the upper engaged by other pairs of pinchers or pullers.

The machine herein to be described coutains a series of side-lasting and closing-down devices, the side-lasting devices impingingl the 3o upper against the sides of the last at the edge of the inner sole and holding the same, while the closing-down devices move over toward and act to lay the projecting edges of the upper over and down upon the inner sole, the

3 5 pinchers or pullers at such time being automatically released, the release being preferably accomplished by or through the movement of the closing-down devices. These sidelasting devices are mounted upon a slide-rod 4o contained in a sleeve pivoted upon auxiliary levers, in turn jointed to side jaws or levers supported upon a two-armed jack adapted to be rotated about a central standard. The double jack in its use is productive of econonly in labor, as one shoe may be jacked or be removed from the jack While another shoe is being lasted. The auxiliary leversare connected together in pairs by rods and their lower ends are always at the same distance 5o apart, and each side-lasting device actuated by the said levers is adapted to stop as soon as it comes against the upper at the side of the last, whether the last is a right or left foot last, each side-lasting device adapting itself to the last, whatever may be its shape in cross-section. The auxiliary levers referred to are pivoted on studs and their lower ends, connected together, as described, are adapted to be moved simultaneously toward and from each other at each side of the last by adj ust- 6o ing devices shown as variable screws, adjustment of the said levers enabling the side-lasting devices to be adjusted simultaneously, according to the length of the last, the said screws being preferably geared together, so as to be rotated simultaneously.

The pinchers or pullers having been engaged with the upper on a last suppported by any suitable heel-pin and toe-rest, the opel ator will start the machine and cause the 7o pinchers to be lifted and stretch and t the upper to the last, which done, a cam previously loose on the main shaft is clutched to the shaft, and thereafter the said cam, through suitable devices. effects the closing of the side jaws or levers carrying the auxiliary levers which aotuate the side-lasting and closingdown devices, the said auxiliary levers also setting into motion devices for lifting the guide-frame containing the movable cross- 8o head supporting the slide-rods carrying the eveners, which at their opposite ends support the pinchers or pullers, the lifting of the guide-frame taking place after" the pinchers or pullers are released, such release as herein provided for being by or through the closing-down devices, the pinchers or pullers and hold-downs (which latter during the pulling operation rest on the inner sole of the last) being thereafter lifted out of 9o the way, so that the jack may be swung around to place the shoe, the upper of which has been stretched and turned over on the inner sole, in position to have its upper prop erly secured to the said inner sole, the jack in its rotation bringing the shoe next to be lasted in place under the pinchers or pullers.

Mounting the pinchers or pullers in pairs 1 upon independent eveners constitutes one important part of our invention. roo

Mounting the side-lasting devices and the closing-down devices at the ends of rods actuated by auxiliary levers connected at their lower ends and pivot-ed on side levers, so thatI one member of a pair of side-lasting devices may stop as soon as it meets the upper, leaving the other of the said pair of side-lasting devices to continue to move until :it meets the upper, is also an important feature of ourinvention. "We have also devised means whereby the slide-bars carrying the eveners, and also the auxiliary levers carrying the sidelasting devices, may be simultaneously adjusted to lasts of different lengths.

Other features of our invention will be hereinafter described, and specified in the claims.

Figure 1in elevation and partial section represents a sufficient portion of a lasting-machine embodying our invention to enable our improvements to be understood, that side of the guide-frame shown at the left in Fig. 4 being omitted, the link b at the left and supporting the lower end of the guide-frame being broken off near its free end, while the link b' at the left and near the upper end of the guide-frame is broken olf quite back to its pivotal point on the central column, (shown broken out,) one half of the hub of the jack being broken out, the front arm of each pair of arms at opposite sides of the hub of the jack being also broken off with the hub inside thepivots G5, as designated by the broken lines near the said hub in Fig. 1. In said iigure the upper and inner soles have been omitted from the last shown at the right, and the said last is shown in section across the shank, while at the left the last shown in cross-section across the toe is represented as provided with an upper and inner sole, the last at the left showing the upper and inner sole in the condition in which it will be left by the pinchers or pullers and side-lasting devices shown at the :right inFig. l after the upperhas been closed down upon the insole. The upper has been omitted from the right in Fig. 1 chiefly to avoid confusion in the drawing and because if the upperwas shown the action of the side-lasting devices could not be as readily seen. Fig. 2 is a detail showing the liftingeslide, which at the proper time is elevated to lift the arms supporting the guide-frame and turn the lever a. and break the toggle-joint which holds up the cross-head D* and the pinchers or pullers. Fig. 3 is a detail of the main shaft, the pulley thereon to give motion to the devices for actuating the pinchers or pullers, the said shaft having a cam adapted to be rotated withthe main shaft at desired times through a clutch to be described. Fig. et is a partial elevation viewing Fig. 1 from the right, Fig. 4c showing that side of the guide-frame omitted from Fig. 1, part of the jack being broken out and two of the auxiliary levers being broken ed, the said ligure showing the last in elevation with an inner sole thereon, the upper being partially broken out, the pinchers or pullers having been omitted to avoid confusion, the screw-rod S1 shown being that nearest the column at the right in Fig. 1. Fig. 5 is a top or plan view showing part of the central column, the arms, the guide-frame supported by them, and the cross-bar having the slide-bars for giving motion to the pinchers, the springs supporting the slide-bars being omitted because fully shown in Fig. 4. Fig. 6 is a detail, to be referred to, of gears on and to connect the shafts S1 for adjusting the side-lasting and closing-down devices in the direction of the length of the last. Fig. 7 is a longitudinal sectional detail of the cam loose on the main shaft and a clutch device to connect it with the main shaft at desired times. Fig. S is a section on the line m2, Fig. 7. Fig. 9 is a section on the line 003;.Fig. 9, the clutch-ring detached. Fig. 10 is a longitudinal sectional detail of the sleeve containing a rod which in practice supports a sidelasting device; Fig. 11, two dierent views of a closing-down device. Fig. 12 shows two views of a side-lasting device detached. Fig. 13 shows an attached side-lasting and closingdown device. Fig. 14 is a detail View, enlarged, of one pair of pinchers or pullers. Fig. 15 is an enlarged view of the evener-lever which will carry the shank-lasting pinchers, the exact construction of said evener not being shown in Fig. 1 because of lack of space.

The frame-work consists, essentially, of a base A, a column A', and a stand A2, they being of proper shape to support bearings for the working parts to be described.

The main shaft A3 of the machine has fast upon it a belt or other power-driven pulley` or wheel, as A4, and, as herein shown, the said shaft has secured to it a pulley A5, (shown as a friction-pulley,) the said shaft and pulley being rotated, it will be supposed, continuously. Herein the said friction-pulley acts at desired times to engage a belt or eqivalent a and move the same whenever the friction between the belt and pulley is suflicient to overcome the weight of the parts to be moved, the said belt being made to hug the said pul ley more or less closely by or through movement of lever, as A4, to be described. pulley A5 and belt have been used in lastingmachines as part of the train of devices to actuate pinchers or pulleys to measure the strain on the upper, and instead of the pulley and belt we may use any well-.known equivalent devices.

The shaft A3 has a cam B, adapted at times to be rotated with the said shaft by or through an intervening clutch device-such, for instance, as that known as the Horton clutch shown substantially in United States Patent No. 260,394--itcontainingaseries of frictionrolls 7', carried by a clutch-ringo", (see Fig. 9%) under the control of two springs r2 and r3, (see Fig. 9,) the said ring having a projection r4, which, when engaged by a suitable catch h, keeps the said friction-rolls from engagement with cam-surfaces of a sleeve-like hub fr of the cam B; but when said projec- This IOO

IOS

IIO

tion is released from the said catch the clutchring is turned by the springs r2 r2, which rest at their ends partially compressed against pins or projections T8, fastto the camB and extended into the annular groove in which the said springs lie, the movement of the said ring by the said springs causing the friction-rolls to be interposed between the camshaped hub T5 and the -inner wall of the hub of the pulley A5, so that the pulley A5 will thereafter, through the clutch, cause the pulley B to be rotated at the speed of the said shaft.

The cam B, it will be understood, may be made to rotate at desired times to thus act upon a roll Bof a leverB2 pivoted at B3, said lever being represented as forked at its outer end to embrace apin, as B4, which, as herein shown, enters an eye in a plunger or bar B5, arranged vertically in bearings in the stand A2, the plunger having an enlarged head.

The catch 7L, referred to for holding the projection r4 of the clutch-ring, is herein shown as a lever pivoted at 2 and having at or near its upper end a roll or projection 3, which is struck by a lug or projection 4, (shown as adjustable by a screw 5 on a rod a to be deseribed,) the said projection 4 acting automatically to turn the said catch and release the said clutch-ring and cause the said cam to move with the said shaft A2 after the upper has been stretched and fitted to the last by the pinchers or pullers and the time has arrived for the side-lasting device to opcrate'.

The column A has at its top suitable ears to support a rock-shaft CL2, having an attached sector a2 and a starting orhand leverai. The sector a2 has jointed to it, as herein shown, a flexible connection, a5, preferably a chain, which is jointed to a rod a, the lower end of which is shown as attached to a belt a, which is extended about the pulley A5, the opposite end of the said belt being in turn connected to a rod a7, jointed at as to an elbow-lever d2, pivoted on a link d10, to be described, the opposite end of the said elbow-leverbeing jointed at Q12 to an arm als, attached to a rock-shaft al, suitably journaled in arms b, to be described. 'lhe short arm of the elbow-lever a2 and the arm am of the rock-shaft @14X constitute a toggle-joint connection between the bifurcated-lever d10 and the said rock-shaft for moving the pinchers or pullers, and .we shall call said toggle the pincher-toggle.

The column A has two pairs of arms h b', pivoted to it, respectively, at 6 7. In Fig. 1, one of the arms b at the front of the figure has been vbroken off, the like arm at the farther side of the machine being shown; and so, also, in said figure l have broken off the outer end of that one of the arms b nearest the front of the machine. The arms Z2 b referred 1o are both shown in Fig. 5, and the front ends of both sets of arms b bare shown in Fig. 4. These arms at their front ends embrace like pins 8, projected outwardly from shaped bars and cross-barconstitutinga vertically-movable guide-frame in which slides the cross-head b4, the latter deriving its movement from a link h5, jointed to the front end of the lever d10.

The column A has a bracket c, provided with a pin c', upon which is mounted a lever c2, the upper or short arm of the said lever being jointed to a link c2, connected by a ,pivot cJK to the right-hand one of the arms b',

before referred to, viewing Fig. 4, the said toggle being straightened when the guideframe is lifted by the lifting-slide d2, the breaking of the toggle by moving the lever c2 by hand lowering the guide-frame for the hold-downs, to be described, to rest on the shoe after the jack has been turned into place and it is desired to engage the uppers by the pinchers.

The inner end of the lever B2 has jointed toit a rod d', connected at its upper end to a lever d2, pivoted at 14 to the column Ah', the

outer end of ythe said lever having a roll 15, (shown by dotted lines in Fig. 1,) which acts upon a lug 16 at the rear side of the liftingslide d2, herein shown as cruciform in shape and adapted to slide in suitable guides d4, forming part of the column A. slide d2' has a pair of studs or projections d and a stud or projection CF, preferably made adjustable by suitable set-screws, as 17, so as to act sooner or later upon the devices to be operated by them-viz., the arms b and the lever CL2-to break the toggle connecting the arms b with the lever d10 or the pincher-toggle, the said projections in rising also acting to lift the guide-frame b2, it being supposed that the lever d4 is at such times in such position as to hold the belt a6 out of contact with the friction-pulley A5. The cross-head b4 (best shown in Figs. 4 and 5) has a series The lifting- IOO TIO

of slots to receive a series ofslide-bars 18,

each bar having pivoted to it at its lower end, as by a pivot 20, an evener 2l, the said bars above the cross-head being surrounded by like springs 22 of proper strength, the lower ends of the said springs resting upon an adjusting device 23,' (shown best in Figs. 4 and 5,) it being pivoted at 24 and having a series of slots, as 25,placed diagonallywith relation to the length of the cross-head, each slot receiving one of the bars 18, a suitable dog or locking device, as 26, engaging the notched end of the said adjusting' device to hold itin adjusted position, the movement of the said adjusting device about its center causing the bars 1 8 to be simultaneously moved toward or from each other, to thus adapt them in position to the length of the last being used. The bars 18 above the springs 22 have screwed upon them suitable nuts 27 to adjust the tension' of the springs. Normally the springs 22 keep the pivots 2O of the eveners up at the same height; but the springs permit the slidebars to stop sooner or later as the cross-head b* rises in the guide-frame, according to the requirements of the upper engaged by the pinchers or pullers.

The eveners 21 have pivoted to them at each end (see Figs. 1 and 14) a pair of pinchers or pulleys composed of a bar e, properly shaped at its lower end to constitute one-half of a pair of pinchers or pullers, the other member e of each pair being shown as a short lever pivoted upon the bar e at 28, the upper end of each member e being connected by a link with a toothed sector-lever 30, in turn pivoted upon the bar e at 300, each sector-lever having a suitable handle, to which is secured a spring 31, attached at its opposite end to one arm 32 of a three-armed lever, one arm 33 of the said threearmed lever acting as a pawl to engage the teeth of the sector-lever, while the other arm 34: of the said three-armed lever is at the proper time, in the operation of the machine, forced against a pin or stud 35 in the crossbar b3 at the lower end of the guide b2, before referred to, the contact of the arm 34 with a pin 35 effecting the release of the pawLmember 33 of the said three-armed lever from the said sector-lever, which permits the pinchers or pullers to release the upper. The eveners may be slotted centrally, as bestshown in Fig. 15, to receive a block 103, mounted on the pivot 20. The pivot 20 also acts as the fulcrum for a lever 105, having a pin 10a, which enters a hole or slot 184 in the evener. The evener is provided with notches at 107 to be engaged by the lever 105 to hold the latter'in adjusted position.

The movement of the lever 105 on the stationary pin 20 enables the evener to be moved longitudinally, as is sometimes necessary to enable the particular pair of pinchers or pull ers carried thereby to be adjusted to the work to be done-as, for instance, when the pinchers are pulling on the upper acrossalast very much steeper on one side than on the other, one arm of the evener-lever should be longer than the other to thus equalize the strain in a better manner; or if an unequal strain on the two sides ot' the upper is required it can be produced by the same means.

The cross-bar b3 referred to has a pin 35 for each pair of pinchers, and 'the lower end of the said cross-bar, provided with a dovetailed groove, (shown best in Fig. 1,) receives suitable hold-down carriages 36 and 10, preferably dovetailedincross-sectionandscrew-threaded, to be engaged by a suitable right and left threaded screw 37, so that the said carriages may be simultaneously adjusted toward and from each other, according to the length of thelast being used. The hold-down carriages 36 and 40 at their lower ends are provided, respectively, with suitable downholds, as Z m', to bear upon the inner sole on the last, said screw-shaft, carriages, and downholds being substantially thev same as in United StatesPatent No. 231,076, granted to us August 10, 1880.

Surrounding the column A loosely above the main shaft is a jack, the hub g ofwhich has extended from it two pairs of arms g g2, which support the pivots 65 on which turn between the arms of each pair of arms the `hubs of the side levers 66, one of each pair of arms g and g2 being broken oit' at the front in Fig. l, one-half of the hub and part of the column being broken out to show the parts within the column. The lower ends of the side levers 66 are connected together by links 67 and 68, jointed at 69 and having a roll 70, the link 68 being extended beyond its fulcrum 7l and provided with a suitable roll, y

The flanged head of the slide B5, when the parts are in the position shown at the right in Fig. 1 acts, as it rises, upon the roll 70 to straighten the toggle 67 68 and force the lower' ends of the side jaws or levers 66 apart, the roll 70 contacting,when the toggle is straightcned, as at the left in Fig. 1, with the lower end of a cross-piece 73. When the toggle 67 68 is to be broken or changed from its position shown at the left in Fig. 1 to that shown at the right preparatory to unjaekinga lasted shoe, the operator will put his foot upon a lever hx, pivoted at h', and elevate the rod h2 against the roll 7 2, thus breaking the toggle. The side jaws or levers 66 are double leversthat is, they have two arms projecting above and below their hubs which turn upon the pivots 65. The upper ends of the two arms referred to are joined bya bar 36X,preferably cored for the sake of lightness. The upper end of each side jaw 66 is provided with suitable holes t'or the reception of suitable studbolts 75, forked at their inner ends to receive between them the auxiliary levers 76, the outer ends of the stud-bolts receiving upon them nuts 77, the said stud-bolts having between their forked heads and the cross-bar 36X, preferably,suitable rubber' blocks, as 78, to constitute a sort of yielding support for the stud-bolts. The stud-bolts may be oscillated about their own center to a limited extent. The lower ends of the auxiliary levers 76 are connected by links 79, and each link between the lower` ends of the side levers is extended through slots in suitable sliding nuts 80, having threaded holes of different diameter, which are engaged by portions of screw-threads on screw-rods 81. Preferably these screw-rods 81 are of different diameters in their length (see Fig. 4) where they are threaded, so that each of the threads at parts of the rods may be passed through the threaded holes in some of the nuts 81 without the threads of the rod touching the threads of the said nuts, each threaded part engaging only its own nut. The threads of the screwvrods engaging the two threaded nuts at the right in Fig. 4 are supposed to be right-hand threads of different pitch, while the thread engaging the nut at the left in Fig. 4 is supposed to be a left-hand thread of yet dilferent pitch, so that by the rotation of the said IOO IOS

IIO

screw-rods the two nuts at the right in Fig. 4 will be moved iii the same direction at different speeds, while the nut at the left will be iiiovedgiii the opposite direction at about the saine speed as the middle nut, said screw-rods being employed to adjust the levers 7 6 and the parts carried by them with relation each to the other to adapt them to lasts of different lengths.

The screw-rods Sl have each a gear p at one end,- and the said gears are operatively connected by two intermediates p p2, so that when one shaft 81 is rotated by a handle p3 on a disk p4, connected to one gear p, the

two shafts 81 will be rotated in unison, but in an opposite direction.

Each lever 7 6 is forked at its upper end and has pivoted therein a sleeve 83, (see Fig. 10,)

through which is extended a rod 84, the front end of which, as herein represented, has a globular head, upon which is mounted the side-lasting device 85, it being made in two parts, (see Fig. 12,) so as to grasp the said globular head, the screw or pivot holding together the lower ends of the side-lasting device, having a spring 86 connected to it and to one of the links 79, the point to which the rod S4 may descend when the side-lasting device is not in contact with the upper being determined by a lug. The reduced part of the rod 84 inside the sleeve 83 is surrounded by a spring n, the outer end of which bears against a tubular nut n', screwed into the outer end of the sleeve 83, the said spring normally pushing the rod 84 toward the last Z2. The sleeve 83 has suitable ears 87, to which is jointed a link 88, which is pivoted at its inner end to a closingdown device 89, in *ign pivoted upoii a side-lasting device 85 at As the upper ends of the side jaws or levers 66 are moved toward each other, they carry with them the auxiliary levers 76, the latter being held at such time at a defined distance apart by the links 79, and as the side jaws or levers are so moved toward each other at their upper ends the upper ends of the auxiliary levers 76 carry the sleeves 83 forward, and through the springs therein acting on the rods 84 cause the latter to push the side-lasting devices 85 against the upper lying at the side of the last, and as soon as the side-lasting devices come against the upper, which 1they do sooner or later during the closing movement of the side levers, (that ,depending upon the shape of the last or whether it is a right or left last), either of the sidelasting devices may stop, the spring n surrounding the rod 84 so arrested being thereafter compressed'during the further movement of the sleeve 83 by thelever 76. In this manner one side-lasting device of a pair may stop against the upper at one side of the last and the other side-lasting device of the pair continue to niove until it is brought in contact with the upper, and that at the opposite side of the shoe-as, forinstance, (see Fig. 1,)

where the side-lasting devicesare both open.) It will be understood that when the side jaws or levers are closed by straightening the toggle at the lower ends the side-lasting device at the other side of the shank will first contact with the upper at that side of the last, and will stop, while in the further closing movement of the side jaws or levers the sidelasting device at the inner side of the shank will continue to move until it comes in contact With the upper at that side of the last. In other words, the side-lasting device which first contacts with the upper at one side of the last serves as a fulcruin about which the other parts turn in play.

Operation: A shoe having been placed on a last and put into the jack and the jack turned to place the shoe under the guideframe, the operator will turn the handle c2 toy break the toggle c3 and cause the guide-frame to descend and the hold-downs to rest upon the inner sole on the last, and then the operator will engage the pinchers or pullers with the edges of the upper and move the lever a4 from the position, Fig. 1,far enough to the right to bring the belt a in frictional contact with the friction-pulley a5 or other device used to turn the lever a9, the operator keeping up such contact and causing said pulley by pulling on the said belt to pull the rod a7 down and depress the long arm of the said lever a9, and cause the pivot an, carried by the short arm of the said lever, to moveto the right with the arm C03, thus straightening TOO the pincher-toggle a9 als and lifting the lever f am, causing it, through the link b5, to lift the cross-head h4, the cross-head acting upon the springs 22, in turn lifting the bars 18 and the eveners and attached pinchers, causing the said pinchei's then in engagement with the upper to Stretch the same firmly about the last between the shank and toe, and especially along the ball and shank of the last, the said eveners adjusting themselves to the upper in the particular line of strain. Vhen the pincher-toggle has been straightened and the pinchers or pullers have been drawn upwardly to sufficiently stretchjthe upper, the proj ect-ion 4, carried by the rod d, will act upon and remove the catch or lever h from engagement with the projection r4, so that the cain B of the clutch, previously stationary, will be started automatically and be made to rotate with the main shaft, the said cam acting upon 'and moving the lever B2 and lifting the slide B5, causing it to act on the toggle 67 68 to close the side jaws 66 and bring the side-lasting devices into operation. 'During this stretching operation of tlie upper the hold-downs rest upon the inner'sole, keeping the last down upon the heel-support and upon the toe-rest 101, both of which may be of any usual or suitable construction. f The further inward movement of the sleeve 83, after the side-lasting devices come to aV bearing upon the stretched uppei' held by the pinchers, causes the closing-down devices89 to act upon the edges ot the upper project` ing above the inner sole on the bottom of the last and lay the said projecting' edges over upon the inner sole, said movement of the closing-down devices carrying the pinchers or pullers with them, and just before the said turning-down devices have partaken of their full movement the arms 3a ot' the threearmed levers carried by the pinchers strike the pins or projections 35 of the cross-bar h3, which results in turning the said levers and removing the arms 33 from the sectorlevers, after which the pinchers or pullers are free to open and release the upper. As soon as the pinchers are released the springs 22 quickly act to elevate the bars 1S, carrying the pinchers. While the side-lasting and closingdown devices are being operated, as described, the lever d2 is being moved by the rod d', connected to the lever B2, and the lifting-slide d3 is lifted, and just about as the pinchers are released the projections CZ d? in succession strike and lift the arms b and the lever a and break the pincher-toggle, the slide d3 descending by gravity as the cam B completes its rotation, the weight of the slide B5 also aiding to raise the inner end of the lever B2 as the smaller radius ot the cam B comes above the roll B, the projection 7'* of the clutch-ring meeting the catch 7L just as the cam B completes one rotation, the stopping of the clutch-ring immediately stopping the cam B, when the jack may be rotated, the guide-trame being held up by the toggle c3.

In the machine herein described the jack rotates in a definite plane, but the top of the inner sole on the last may occupy different horizontal planes, that depending' upon the thickness of the inner sole and the particular shape of the last; but inasmuch as the pinchers or pullers and their actuating devices are carried by a vertically-movable guidei'rame having attached hold-downs to rest upon the inner sole, it will be apparent that this guide-frame may come to rest always in the same relative position to the shoe being lasted, so that the pinchers or pullers and the side-lasting devices are always in proper relation to the surface and edge of the inner sole, no matter what may be its thickness, and in practice the jack is moved to swing the shoe into position while the guide-frame is elevated, and then the trame is lowered by the toggle-lever a2 c,

Ve claiml. A lasting-machine containing the following instrumentalities, viz: a column, a series of pinchers or pullers to engage the upper, a series of eveners to support the said pinchers or pullers, devices supported by the said column to actuate the said eveners, and a rotating jack having two sets ot' side-lasting devices and means to operate them, the hub of the jack rotating about the said column to bring either jack in succession under the pinchers or pullers, as and for the purpose deA scribed.
