Specification of Letters Patent.

Patented Sept. 13, 1921.

Application filed October 6,1916. Serial No. 124,187.

To all whom it may concern Be it known that I, MATTHIas BROOK, a citizen of the United States, residin at Boston, in the county of Sufiolk and tate of Massachusetts, have invented certain Improvements in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. v

This invention relates to lasting machines and is herein illustrated in its application to a type of machine shown and described in United States Letters Patent No. 018,477, granted upon my application on I eb. 27, 1912. It is to be understood, however, that in man of its aspects the invention is not limited to machines of that particular type.

Among its objects the invention aims to relieve the operator of much of the labor which has been necessary heretofore in the operation of well-known commercial ty es of lasting machines, and by thus enabling the operator to concentrate his attention more fully upon the condition of the shoe materials in the course of the lasting operation,

a to improve the product while also eliminatmg unnecessary fatigue. With this and other objects in view, a feature of themvention consists in a novel organization wherein power is utilized to effect relative movement of end lasting means and a shoe in a direction transverse to the plane of the shoe bottom to perform, for example, what is commonly known as the upwiping of the upper around the end of the shoe. The

construction shown comprises power means for raising the toe wipers to upwipe the upper around the toe, with manual means enabling the operator to hold the'wipers closed effectively around the toe in the upwip ng operation. The operator isthus not only relieved of the arduous labor of raising the wipers against the resistance of the shoe materials, but is also enabled to concentrate his attention upon the proper conformation of the wipers to the shoe under the degree of pressure required by the particular character of the materials in order to render the upwiping operation properly effective. Ad: vantageously the illustrative construction provides, for the upwiping operation, a

power shaft with a clutch control enabling the operator to stop the upwiping movement of the wipers at any point or to cause a reversal and a repetition of such movement. As a related feature, the invention also rovides for the use of power means for e ecting relative movement of the shoe and the wipers to compress the overwiped margin of the upper on the bottom of the last, the construction shown including a friction clutch control whereby relative slipping movement between parts of the clutch is availed of to insure both against undue compression of the shoe materials and against breakage of the machine. A further advantage of the illustrative construction is that the operator may control the force applied in the compression of the materials in accordance with the force which he uses in holding the parts of the clutch in engagement.

A further feature of the invention, as applied to a machine wherein the shoe and end embracing wipers are relatively movable in a direction transverse to the plane of the shoe bottom, for example to unwipe the upper, comprises novel means of. control to stop such relative movement at a determinate point. The construction herein shown comprises controlling mechanism automatically perative to stop the power effected upwiping movement of the wipers in proper position for the subsequent overwiping operation. The invention thus marks a substantial and important improvement over prior constructions, wherein it has. been necessary for the operator to rely upon the degree of resistance encountered by the wipers held manually against the shoe in the upwiping operation as an indication of the proper point to terminate such operation and begin the overwiping operation. This has re uired heretofore an undue concentration 0% the operators attention in order to insure against undesirable reaction of the stock as a result of moving the Wipers too far in the upwiping operation, and has frequently resulted in failure s0 to coordinate theupwipin and over-wiping operations as to produce the best results in drawing and wiping the upper ti ntly over the outer edge of the sole or inso e. Advantageously, in the illustrative embodiment of the invention, the upwiping movement of the wipers is thickness of the insole.

. movement over the shoe is imparted to end embracing wipers intime relation to the clamping of the end of the shoe, or to the jacking of the shoe. In its embodiment of this feature the construction shown comprises power means for jacking or clamping the shoe in aheel embracing band by moving the shoe toward the band and closmg the band about the shoe, and for imparting substantially simultaneously to the heel v seat wipers an operativemovement inwardly heel seat face of the last, is

the'upper properly over the heel seat.

overtheshoe. The most difficult part of the heel lasting operation in the illustrative type of machine, wherein the upstanding marginal portions of the upper materials are broken down and wiped inwardly over the thus performed automatically by the power operating means, and on some shoes such movement of the wipers will suffice to shape the margin pf 11 order to permit further operation of the wipers when required, the illustrative machine is also provided with means whereby the wipers may be disconnected from the 1 power operating means and further operated manually.

In still other aspects, the invention aims to facilitate the return of parts of the machine to starting position following a lasting. operation on the shoe. In this part of the invention a feature is to be recognized in a novel organization of means for effecting and controlling reverse relative movement of lasting means and the shoe. In its embodiment ofthis feature, the machine herein shown has power means for lowering the toe wipers at a determinate time in the power" operationxof the machine, the illustrative construction including also stop mechanism automatically operative to dis connect the wipers from the source of power and stop their movement at a determinate point. novel organization whereby reverse relative movements of the toe and heel end lasting mechanisms and the shoe are effected in time relation. In the construction shown the toe lasting mechanism' is lowered by power to its starting position as an incident to the unjackingof the shoe, thus effecting an important economy of time and effort on the part of the operator in trative type of machine.

It is a well-known condition in the shape Still another feature comprises a the use of the illusof many modern lasts that the opposite side faces at the forepart slope in the same direction laterally of the last toward the edge of the last bottom, the direction of the slope in a right last being the reverse of that in the left last. Provision has accordingly been made heretofore for a component of relative movement between end embracing wipers and a shoe in a direction laterally of the shoe in the upwiping operation to insure effective pressure of the wipers against the shoe at the opposite sides of the forepart and to position the wipers properly for overpiping the upper at both sides of the shoe. A further feature of this invention consists in novel means of control to insure a proper component of relative lateral movement in operating on different shoes. In its embodiment of this feature the construction shown comprises controlling means for such lateral movement which is adjustable in accordance with the requirements of different shoes without special attention from the operator. More particularly, the construction herein shown comprises controlling means to determine the proper inclination of the path of upward movement of -the toe wipers which is adjusted reversely for right and left shoes by the positioning movement of the heel lasting mechanism in accordance with the lateral swing of the respective shoes. By such means both the direction and the exteht of the lateral component of the upwiping movement are determined in accordance with the requirements of each shoe.

The above and other features of the invention, including a novel construction of end embracing wipers and -,various details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and pointed out in the claims.

Fig. 8 is a plan view of adjustable heel wiper plates; and a Fig. 9 is a detail of the pawl control. a i The frame 2 of the machine supports a toe lasting mechanism and a heel lasting mechanism between which are located the toe rest 4.- and the heel rest 6. The heel lasting mechanism is carried by a frame 1 sliding longitudinally in ways in a carriage 3 which is connected pivotally with the frame by a pin 5 located beneath the last in a line at, or approximately at, the point of intersection of the median lines of the heel and forepa-rt of the last. Preferably, the pin is adjustable longitudinally of the last in accordance with variations in said point of intersection in different lasts.

The carriage 3 with its heel lasting mechanism is movable freely about the pivot 5, the carriage sliding freely over the frame 2 and being supported by rolls 13, shown in Figs. 1 and 2, which travel on a curved track, the movement being limited by stops 7 (Fig. 2), adjustably mounted on a right and left threaded screw 9 at points equidistant from the middle line of the machine. The screw is provided with a crank for adjusting the two stops toward and from the middle of the machine. The stops serve to limit lateral swinging movement of the heel. lasting mechanism and, when they have been adjusted into the right position for a right last, for example, they will be correctly lo cated also for the left last and for all lasts of the same style. The carriage may be provided with a locking device such as a latch adapted to cooperate with either of the stops 7 as disclosed in my patent previously noted, so that the operator may, by a single movement, release the latch and move the heel lasting mechanism laterally about its pivot 5.

The toe lasting mechanism is carried by a head having a depending column 8 guided in the frame for vertical movement and having an offset interiorly threaded portion 10 cooperating with and supported by a power operated screw 11 by means of which the toe lasting mechanism is raised and lowered, as later explained.

The head of the column 8 supports a plate .12 which, with the superposed toe lasting mechanism, is adjustable longitudinally of the machine by a screw and hand wheel 14 for adaptation to shoes of different lengths, the operative position of the heel lasting mechanism lengthwise of the machine being constant and thetoe lasting mechanism stop block and its alone being lengthwise adjustable. Above the plate 12 is a second plate 16 (Fig. l) which is automatically movable in a right line transversely of the machine and laterally of the last by means shown in F '7 and which will be later described. The plate 16 has an undercut groove (Fig. 1) in which slides a correspondingly formed rib depend.- ing from a plate 18, said groove and rib ing curved about a center which is located substantially under the end of the toe of the last when a shoe is in the machine. A screw rod (Fig. 1) having a hand wheel 20 effects and maintains adjustment of the plate 18 about the pivotal connection at said center. 'From the superposed plate 18 rise projections to which is pivotally connected at 21 a tipping head 22 which is adjusted and maintained in adjusted position about said pivot 21 by a screw and hand crank 24 to adapt the toe lasting mechanism to the inclination of the forepart of the last bottom.

The tipping head 22 is formed in its upper face as a half sleeve, upon which fits a cap plate 26 having a complemental formation to present a long bearing extending lengthwise of the shoe. In this bearing is mounted the cylindrical stem 29 of the toe wiper carrying plate 28. This stem has a lug projecting through a slot in the bearing and engaged by a forked block which is movable by a screw and hand crank 25 for adjusting the toe wiper carrying plate about an axis extending lengthwise of the machine to adapt the wipers to the transverse inclination of the forepart of the last bottom. Within a horizontal guideway formed in the wiper carrying plate 28 are located cam plates 30 with which the wipers 32 are de tachably connected, said cam plates having the usual cam slots therein (not shown) in which stand roller studs screwed to the carrying plate 28 and causing the wipers to close when they are advanced. Advancing movement of the wipers is effected through a lunger rod 34. operated by a hand lever 36. leans hereinafter described are provided for lifting the toe head whereby the wipers, which will have been caused to embrace the toe portion of the last below the last bottom, may be caused to wipe up and mold the upper to the side faces of the toe portion of the last. After the wipers reach the plane of the shoe bottom, they are further advanced and closed to lay the upper materials inwardly over the innersole upon the last bottom. The general organization of the machine thus far discussed except for details related to novel features hereinafter described is, or may be, substantially the same as is fully shown and described in my said prior Patent No. 1,018,4J7, and need not be here further explained.

The machine as shown herein is provided with a toe embracing band and with wiping mechanism corresponding generally in construction and operation to the toe embracing and wiping mechanism described and illustrated in detail in prior United States Letters Patent ,No. 1,284,870, granted upon my application on November 12, 1918, and ac cordingly these parts will only be described as to their essential features.

The toe embracing band 38 constitutes an outer close-fitting form or mold at the edge of the shoe bottom, while the wipers 82 are operating to compress the upper on the margin of the shoe bottom, whereby a sharply defined angular edge is provided at the iunction of the side and bottom faces of the shoe. The band is mounted direct below the acting edge of the toe wipers 82 and comprises a supporting chain and a non-abrasive lining member. The chain is connected at its outer ends to transverse levers 40 which are fulcrumed on slide bars 4-2 mounted within the wiper carrying plate 28 for movement lengthwise of-the machine. The ends of the slide bars 42 remote from the band are pivotally connected to a cross head l lwhich is pivoted to constitute a closing pressure equalizer on the rear end of a slide to (Fig. 1). This slide 46 has a lost motion connection with the hand lever 36 by which the wipers are operated so that there is lost motion allowing the open wipers to lee manipulated for embracing and upwiping an upper around the toe of a last without necessarily disturbing the band.

The free outer ends of the transverse levers 4C0 are connected by springs d8 to an equalizing bar 50 fulcrumed to the toe wiper carrying plate 28 at 52. The springs act through the levers to tension the sides of the band longitudinally of the last and cause the band snugly to embrace the toe of a shoe in the machine. They also act as relief springs to allow slide 46 and the bars 4-2 to complete the stroke given by the wiper operating lever 36 after the band has tightly gripped the shoe and can be closed no farther.

The slide bars 42 have cam faces or inclines on their outer edges which cooperate withstops M to wedge the end portions of the band inwardly for closing the band hard against the sides of the toe in response to forward movement of the slide bars and concurrently with the rearward pulling movement on the band ends. The stops 5% are formed as cams on the inner arms of levers which are fulcrumed to fixed lateral extensions of the plate 28 and the outer ends of these cam levers are engaged by springs 56 through which pressure is applied from the previously mentioned cross head at& for holding the cams or wedge abutments to their work and tending to turn the cams in the direction to supplement the action of the inclines in forcing the end portions of the toe band inwardly. The friction of the relatively moving parts is such that under the action of the springs 48 and 56, the slide bars l2 hold the band hard closed against the shoe while the lost motion between the slide 46 and lever 36 is utilized in backing off the wipers to uncover the tacking line on a McKay shoe or to permit the toe wiring operation on a welt shoe.

The toe band is movably supported on a bracket which is formed to present a shelf upon which the middle portion of the lower edge of the band rests. This bracket, and therefore the toe band, is preferably supported for adjustment lengthwise of the machine and relatively to the wipers by a rod connected to the bracket and provided with a hand wheel 58 (Fig. 2).

The right and left sides of a last are both inclined toward that side of the shoe bottom which is outermost when the last is in upright position, or toward the right in a right shoe and toward the left in a left shoe. It is highly desirable to present the wipers at the plane of the shoe bottom in the same rclation to the two sides of the toe so that when they are closed they will lay the upper into position to be fastened at the same distance from the edge and inside the sewing line on both sides of the toe of a McKay shoe, and will force the upper into the corner at the base of the sewing rib at both sides of a welt shoe.

According to the present invention, novel mechanism is provided for moving the wipers transversely of the machine and of the last in one direction for right shoes, while the wipers are being elevated to wipe the upper over the sides of the last, and in the reverse direction for left shoes. The plate 16 underlying plate 18 and overlying and having the transverse tongue and groove connection with plate 12 (see Fig. 1) is extended (Figs. 2 and 7) toward the rear of the machine where it is bifurcatml and provided with inverted hook-shaped bearings 161 (Fig. 7) to support and journal a sleeve 60. A block 62 having an elongated slot therein is seated over this sleeve between the bearings and is fixed thereto as by a set screw so as to be rigid with the sleeve. The slot in the block is enlarged laterally at its upper end to form a seat for the sleeve and is of such length as to permit the maximum upward movement of the lasting plate 1.6. The lower part of the sleeve is channeled to receive a squared shaft Gd: fitting snugly within the slot of the block for relative sliding movement. The sleeve channel coincidcs in width and alincment with the block slot below the sleeve seat and constitutes in effect a continuation of that portion of the slot in block 62 in which the squared shaft er may slide. The bearings have the opposite edges of their lower openings spaced to permit substantial inclination of the block 62 without extending said edges into the line of the slot.

The ends of the squared shaft are reduced and rounded and mounted in journals formed by an extension 641 of the frame 2 and by an offset extension 661 at the upper end of a hollow standard 66 carrying a holddown stem and certain operating parts later to be described. Adjacent to the journal 661, a slotted link 68 is mounted on and fixed to the squared shaft 64 and extends downwardly. A block 681 carried by an adjusting screw 682 is mounted in the slot of the block 68 and may be adjusted lengthwise thereof by the screw 682. This block is pivotally connected to a second block 701 mounted to slide in an elongated slot formed in the upper end of a bell crank lever 70 pivoted to an offset 662 of the standard 666 and having its lower end bifurcated to receive a pin upstanding from one end of a horizontal lever 72. This lever is pivoted on a bracket 663 of the standard and extends longitudinally of the machine and is connected by a link 74 to a bracket 76 on the carriage 3 on which the heel lasting mechanism is mounted, as shown in Figs. 1 and 2.

The opposite side faces of straight lasts are substantially the same with practically no inclination. The side faces of crooked lasts, however, are inclined. The squared shaft 64 may be adjusted so that with the heel carriagepositioned in the longitudinal median line of the machine, its side or active faces will be substantially vertical. This adjustment may be secured by operating the screw 682 when the heel carriage is in central position. This screw will move the block 701 and the sides of the slot in bell crank lever 70 will operate as a wedge to swing the slotted link 68 to turn the squared shaft in its bearings. It will be evident that when the toe lasting head, including plate 16 is moved vertically upward by the power operated mechanism, previously referred to, the slotted block 62 will be moved upwardly with it. As the block rises, the side faces of the squared shaft 64, when inclined from the perpendicular, will engage with the sides of the slot in the block 62 and by reason of their inclination, will act asa wedge against the block to force the block with its connected plate 16 and the toe lasting head transversely of the machine in the direction determined by the inclination of the side faces of the squared shaft.

This inclination is changed from a determinate angle to the perpendicular for a right shoe to an opposite and corresponding angle to the perpendicular for the left shoe (of a pair made on a crooked last) when the heellasting mechanism is swung, from the position it occupies for the right shoe to the opposite position for the corresponding left shoe, which is reached when the locking device carried by the carriage 3 of the heel lasting mechanism cooperates with the opposite stop 7. This reverse inclination of the squared shaft 64 obviously is effected through the connection of the link 7 4 with lever 72, movement of which operates the bell crank lever 70 and turns the squared shaft through the connections previously described. The amount of movement transmitted to the lever 72 and bell crank lever 70 will vary with the swing or crookedness of the last and will increase the inclination of the side faces of the squared shaft proportionately to the crookedness of the last. In other words, the more crooked the lasts, the greater will be the inclination to the vertical of the active faces of the squared shaft 64 and the amount of the transverse movement of the plate 16 and toe lasting head. will be correspondingly increased. to effect an upwiping movement with a proportionately increased component of lateral movement. The automatic adjustment of this inclination by movement of the heel carriage may be varied for a last of given swing through adjustment of the block 681, as described.

The lifting screw 11 for the toe lasting head previously referred to is in the form of a spindle having its upper portion, only, threaded, the spindle extending vertically downward and being journaled in a portion of the machine frame. It preferably carries a collar below its threaded portion (seen best in Fig. 5) having a thrust bearing on the upper end of the machine frame. At its lower end, it carries a downwardly facing beveled gear 78 attached to the screw spindle by a suitable collar and engaging opposite beveled gears 80 and 82 loosely mounted on a counter shaft 84, journaled at its forward end in the machine frame and carrying a pinion 86 at its rear end. This pinion is in meshwith a beveled gear 88 se cured to the face of a pulley 90 continuously driven from a suitable source of power, such as the usual line shaft.

The opposed inner faces on the beveled gears 80 and 82 are formed with conical clutch faces and a sleeve 94 keyed to the shaft 84 between these beveled gears and continuously rotating with the shaft, is formed at its opposite ends with corresponding clutch surfaces and is arranged for sliding mm'ement to and from neutral position and alternately to engage and rotate the beveled gear 80 to rotate the screw 11 in a direction to lift the toe lasting head, and toengage and rotate the beveled gear 82 to rotate the screw 11 in a reverse direction to lower the head. a

.The sleeve 94 is formed with a circumferential groove, into which extend pins carried by the ends of an embracing yoke 96 formed as an extension from a controlling rock arm 98 pivoted to the frame and Connected by a link 100 at its rear end to a crank arm at the rear end of a'rock shaft 102 journaled in the machine frame and extending forwardly to the'front of the machine where it is rigidly connected to a double acting treadle 104 at a point between its ends. Actuation of opposite ends of the treadle downwardly will connect the clutch sleeve 94 with opposite beveled gears and S2 to alternately raise and lower the toe lasting head, and movement of the treadlc to a substantially horizontal position (Fig. 1) will shift the sleeve 94 to neutral position. The friction clutch Surfaces permit the driving mechanism to slip and prevent breakage when the predetermined pressure for'which they are arranged has been ap plied in depressing the toe lasting head to iron down the overwiped upper matc rials on the thread face of the insole.

As I have previously stated, in themanually operated or manually controlled lifting movement of the toe lasting head, it is dil cult, if not impossible accurately and uniformly to arrest upward movement ofthe lasting head with the wipers positioned in the proper plane relative to the insole, since the operative must coordinate the operation of the treadle to stop the movement of the head with the feel of the wipers which are being pressed against the sides of theshoe as'the lasting head rises. To obviate this diflicult'y means are provided automatically to arrest upward movement of the head with the wipers in the proper plane for the particular shoe being lasted.

Accordingly, to the front end of the rock arm 98 is pivotedthe lower end of a rod 106 extending upwardly through spaced brackets (Fig. 5) proiecting from the frame. Above the lower bracket, a plate 110 is attached to the, rod and hasits outer face formed with. downwardly inclining ratchet teeth. A channeled stop block 112 is mounted on the plate 110 for vertical sliding movement and is formed with an offset 113 positioned in vertical alinement with the upper end ofa set screw or abutment 11 i adjustably mounted in an extension 116 of the olfset portion 10 of the toe lasting head 8. The block 112 carries pawls 111 (Fig. 9) mounted on the pivot pin of a rocking link 118 connected to a parallel link 1.22 by an upstanding cross bar 120 with a coiled spring anchored to block 112 and connected to the free end of link 122 and normally tendingto swing the pawls 111 (Fig. 9) into engagement with the ratchet teeth.

The block 112 is supported and determinately positioned on they ratchet plate by the engagement of the. forward end of a lever 146'under the free end of the upper link 122, releasing the pawls from the ratchet plate and permitting the block to be lifted and supported in desired position by said lever. The lever itself is operated deterniinately to position the block 112 by certain connections to a hold-down member 135 arranged to engage the sole of the shoe to be lasted, this member through said connections, and by movement to position of engagement with the sole, swinging the lever 14-6 determinately to position the stop block 112. T he hold-down member 135 may be of an desired and suitable construction. For use with welt shoes, it will be of a construction to engage the curved lip of the insole as shown in F 5 and in practice engages the lip at a point centrally of the toe of the shoe.

A spindle 128 is guided for vertical movement by the hollow standard 66 and is provided at its upper end with a head 130 having a transverse bore to receive a horizontally extending spindle 131 whose forward end has the hold-down member 135 clamped thereto. and whose inner end carries a rock arm 132 housed within a bifurcation of the head 130. One side of the head 130 is channeled to receive a vertically movable plate 136 having an outwardly extending bifurcated portion, within which is seated a pin 18S offset from the rock arm 1232 and operating to slide the plate vertically when the shaift 131. is oscillated. A coiled spring operating against a pin at the top oi": the plate normally presses its bifurcated oilset downwardly against the pin of the rock arm.

The base of the plate 136 is formed with a flange 140 formed on an arc concentric with the axis of the spindle 128 and engaged by the notched head of a vertically movable link 14:2. llhe arc-shaped flange permits the spindle 12S and its head and hold-down to be swung in an are without. disengaging the link from the plate The lower end of link 14-2 is pivotally connected to one end of a lever 141 which is pivoted intermediate of its ends on the trame ot the machine. and has its forward end connected by a ball and socket joint with the rear arm oi the lever 116, extending substantially at right angles thereto and join-naled intermediate its ends on a stud projecting from the machine frame. The forward end of this lever 14:0, as previously stated, extends beneath the free end of link 122 controlling the pawls of the block 112.

In the raised position of the hold-down spindle 128, the outer end o l the lever 140 is swung upwardly from the position shown in Fig. 5, sliding the block 1112 upon the plate 110. lVhcn the hold-down spindle is pulled downwardly by a troadle 148 to bring the base of the hold-down against the insole this end of the lever is lowered and the block 112 slides downwardly with it. If the hold-down 135 is pressed downwardly subsequently to engage its edge with the lip of the insole, for instance, additional downward movement is given to the block, or if the toe end of the shoe is upwardly inclined, the adjustment of the hold-down in conformity therewith may lift the block 112 to a slight extent. Under all conditions the plane of the toe end of the insole controls the position of the block 112 so that the block will occupy a position determined by the plane of the toe end of the insole of each particular shoe. To insure downward movement of the block 112, in case the bar should stick, a stud 115 projects from the block 112 below lever 146 (Fig. 9).

The offset 113 of the block is always in vertical alinement with the end of the set screw 114 carried by and moving upwardly with the toe lastin head, and the connections from the ho d-down spindle to the block are so proportioned as to position the offset for engagement by the set screw 114 at that point in the rise of the lasting head when the wipers have reached approximately the plane of the last bottom. As soon as the set screw engages the offset, the block 112 is lifted from the end of the lever 146, its pawl at once engaging the ratchet of plate 110, lifting the plate and its rod 106 to rock the arm 98 and slide the clutch sleeve 94 to neutral position, automatically stopping upward movement of the head at the desired point. Accuracy in the time or oint of clutch retraction may be assured 'y adjustment of the set screw 114 when the machine is first assembled and tested. The set screw also enables adjustment to be made at later dates to compensate for wear in the block actuating levers, etc. When the head 8 is lowered for a second upwiping movement, the block 112 slides down to its initial position of support by the end of lever 146.

The hold-down spindle and its connected parts are held locked in adjusted position by suitable means which may be released when desired to permit the spindle to be again elevated. The treadle connections, and the locking and releasing means, may, and as shown, conform substantially to the holddown controlling and operating means shown in United States Letters Patent to Keyes, No. 1,120,822, granted DQQUlIllJGi' 15, 1914. Their specific construction, however, forms no part of the present invention. Briefly, the spindle 128 is" pulled down against the resistance of a spring by a foot treadle 148 having a ratchet plate connerted. therewith, a locking pawl for the ratchet plate being released by pressure against a knee (or thigh) lever 150 connected by a rod 152 with the locking pawl, the spring thereupon elevating the hold-down.

The normally idle shaft 92 on which the pulley 90 is continuously and freely revoluble, extends lengthwise of the machine and. is provided at its end with a crank arm 154 and adjacent to the crank. arm with an eccentric 156. The shaft has a'clutch sleeve 158 (Figs. 2 and 5) keyed thereto provided with a toothed clutch face and normally urged by coiled springs (Fig. 2) to engage its toothed clutch face with a similarly; toothed clutch surface on the hub of the pulley 90. A rib 160 (Fig. 4) is formed on the periphery of the sleeve 158 and is inclined to act as a cam, against which normally bears an arm 162 rigid with and extending rearwardly from a hub 163 mounted 011 a spindle carried by the frame. This arm operates normally to hold the clutch sleeve out of engagement with the pulley.

A second rigid arm 164 projecting forwardly from the hub has its forward end normally depressed by a pin 16? offset from the rear end on a pivoted arm 168 journaled on a spindle at the forward end of the machine frame and normally pressed downwardly into engagement with. the arm 164 by a spring. Between the front and rear arms 164, 162, a vertical crank arm 166 rises from the hub 163 and has its upper end pivotally connected to the rear end of a rod 170. The forward end of rod 170 is pivoted to the rear end of a lever 172 (Figs. 1 and 2) pivotally hung in a saddle depending from the frame and operable by knee pres sure momentarily to depress the rear arm 162 and permit the clutch sleeve 158 to enwith the driving pulley and rotate the shaft 92 through one revolution The knee lever is immediately released and the arm. 168 operating against the front arm 164 of the hub 163 immediately elevates the rear arm 162 to engage the cam 160 and retract the clutch at the end of one revolution of the shaft 92.

At the base of the machine and extending transversely of the shaft 92 a bar 1174 (Figs, 5and 6) is guided for horizontal reciprocating movement and has its end formed as a yoke 17 6 to en'ibrace the eccentric 156 with sul'istantial clearance between one side of the embracing yoke and the com-nitric. The forward end of the bar is provided with a plate 176 guided in the front of the machine frame and formed with a ratchet surface, with which a pawl. at the rear end of a pivoted finger 180 coiiperates. A spring 181 is interposed. between the yoke portion of the bar 174 and a pin upstanding from the central pivoted. portion of the finger 186 and normally acts to hold the pawl end of the finger in engagement with coiled finger 180 when the finger is in position to cooperate with the teeth on the plate 178. The tension of the coiled spring 181 normally tends to return the bar to its forward position and is permitted to do so when the toe lasting head, in its return movement to lowered position after a toe lasting operation, has reached lowered position. The eccentric operated rearward movement of the bar tends to shift the clutch sleeve 9st in the direction to engage and rotate gear 82 to lower the toe lasting head as will be hereinafter explained. There are two rotations of the shaft 92 to each work cycle; the first occurs at the beginning of the cycle (when the lasting head 1s already lowered) to jack up the last and shoe, the pawl finger 180 at that time being ineffective to hold vthe bar 174, as will be explained and the second rotation is effected at the end of the cycle to release the last and shoe, and is effective to lower and in accordance with a portion of this invention, automatically to stop the toe head.

The yoke 96 operating the clutch sleeve 94 carries an adjustable screw 184. (Figs. 1 and 6) to which is anchored one end of a coiled spring 186, the forward end of the spring being anchored to the bar 174: adjacent to its yoke portion 176. Obviously, with the toe lasting head in its raised position and} with the clutch sleeve 95L in neutral position, (Fig 1) at the end of the lasting operation actuation of the knee lever 172 will cause the shaft 92 to be rotated and move the bar 174 rearwardly and will,

through the spring connection 186, shift the clutch sleeve from a neutral position to a position where it'engages and rotates the beveled gear 82 to lower the toe lasting head, the pawl 180 holding the yoke in rear- 1 wardly moved position against the tensioned spring 181.

When the toe lasting head approaches the limit of its downward movement, a rod 188 (Figs. 1, 5' and 6) having its upper end attached to the plate 12 of the toe lasting head and guided for vertical movement, engages the front end of the pawl finger 180 and lifts the pawl from engagement with the rack plate '17 8, whereupon the tensioned spring 181 will move the bar 17 1 toward the front of the machine and by relieving the tension of the spring connection 186, will permit the clutch sleeve to be moved from engagement with the gear 82 into neutral position. The pawl finger will thus be held in inoperative position until the toe lasting head is again raised.

The rotation'of the crank arm 15 1 through the revolution of shaft 92 reciprocatcs a link 190 (Fig. 1) pivotally connected at its lower end to the crank arm, effecting an oscillation of a disk 192 carrying a driving dog engaging teeth formed on a ratchet wheel 194 to turn a cam shaft 196 on which said ratchet wheel is rigidly mounted. Actuation of the cam shaft 196 through the space of one tooth by the reciprocation of the driving link 190 is first effected when the last and shoe have been positioned upon the heel and toe rests and have been moved to engage the heel clamping band as previously described.

This first actuation of the cam shaft causes cams and connections operated thereby to jack the shoe and last upwardly and backwardly against the heel clamping band and to move the heel clamping band firmly to embrace and conform to the heel end of the last and automatically to operate the heel wipers. In this position the shoe and last is held while the toe and heel end lasting mechanisms are operated to wipe the marginal edges of the upper over the insole to which they are subsequently tacked. A second actuation of the cam shaft by operating the knee lever 17.2 is effected at the end of the lasting operation and results in lowering the toe rest, retracting the heel wiping mechanism and clamping band from the last and shoe and in moving the heel pin with the last and shoe forwardly out of the heel clamping band, at the same time lowering and stopping the toe head.

These cams and their operating connections need not be described in detail herein. As shown, they correspond with those described and illustrated in prior United States Letters Patent No. 1,018,477, previously referred to. Briefly, the heel lasting mechanism is movable with its frame lengtlr wise of the carriage 3 from a retracted position, which permits of the convenient mounting of the last on the last spindle 6 to a. predetermined operative position which is maintained during the jacking and lasting operations by a latch carried by the heel lasting head which engages a projection on the side rail of carriage 3 (Fig. 1), and is automatically released by a cam mounted on said cam shaft 196 at the end of the lasting operation. The last spindle 6 is carried by a slide 198 (Fig. 3) which is movable lengthwise of the machine on the carriage 3 and. relative to the heel lasting mechanism. l or the purpose of effecting lengthwise movement of the slide, its upper face is racked and a pinion 200 carried by a shaft 292 is arranged to be operated by a hand wheel see (Figs. 1 and 2) to move the heel rest rcarwardly toward the heel clamping band and lasting mechanism. A coiled spring 206 (Fig. normally tends to move the heel rest 6 forwardly away from the heel band and lasting mechanism, and the hand wheel 204i is provided with a suitable pawl and ratchet mechanism to retain it in adjusted position. The pawl may be manually released but may be, and preferably is,

automatically released when the heel lasting meclianism is released at the end of the lasting operation so that the shoe is not pulled rearwardly to scrape and mar the toe 1y abrasion from the toe rest.

The automatic lifting of the toe rest is efl'ected. as previously described, after the slide 198 has been moved rearwardly to engage the heel end of the shoe and last with tlraheel claniping band, indicated at 210, (Fig; 3) and to lift the heel end of the last and shoe throughcam plate 209 and abutment screw 211 so as to present the bottom face of the shoe in the plane of theheel wiper plates. Actuation of the camshaft to eflect this jacking operation also and coincidently rotates a second cam 212 operating against a roll carried by a pivoted arm 214 (Fig. .4) which is in turn connected with a bar 216, and an angular lift rod 218 to a lever 220 (Fig. 3) whose lower end engages a second lever 222 fulcrumed 1n the carriage of the heel lasting mechanism. iThis lever, as shown herein and in accord ance withthe construction of prior Patent No. 1,018,477, has a vield ingsprmg connecupper end is notched to receive the endot a rod22tiarranged 1n machines as hereto tore constructed to efiect a prelii'nil'iary par tial closing movementot the heel wipers. This rod,together with an actuating rod 228 forefl'ecting bodily longitudinal movement of the wipers and causing themto close, and a l heel clamp operating pluno er 2230 con nected to the block 224, are guit ed for longitlldinal movement through a head 232 of the heel endlasting mechanisms The rod 228 has a latching sleeve 234 mounted upon its rear end and formed with an abutment. From this sleeve an arm 236 depends and is pivotally mounted at. its lower end on a bracket extending from the head. Between its ends itis connected by a link 238 with the end of the lever 222operated through cam 2l2,so that, when said cam is actuated and the block 224. is moved as above explained movement is also imparted to the sleeve 234. a i

ing members of novel construction (Fig. 8)

comprising curved wiper plates 2% pivedges and securedto carrier: plates 248,

ently to be adjusted relatively to their cara rier plates to vary the contour of the wipers. Preferably, the under faces of the carrier plates 248 areundercut to receive therear portions of the plates 246.

Adjacent to their outer forward ends the carrier plates 248, as in prior constructions,

arc apertured as at 249 to receive the pivots of wiper actuating links 256. whose rear ends are pivoted toan equalizing lever 258 to which the torwa rd end of the actuating rod 228 is pivoted. The carriers are also provided with divergent slots 260 in which stand rollers carried at the forward end or 7 ends of links 262 whose rear ends are pivoted to the rod 226. These rollers, as heretofore. have plus extending upwardly through cam slots formed in the upper plate of the lasting head 250 and extending at an angle to the slots 260 of the carrier plates, as shown .in Fig. 2;

When the -am 212 is operated to slide the block 224- forwardly, the rod 226 will more the links 262torwardly, their rollerpins being moved by the cooperating cam slots to urge the rollers against the sides of the slots 260 of the carrier plates andin a direction to effect what in prior machines has been a preliminary partial closing movement of the wiper plates, this inoi 'ement alone not being suflicient' to effect a full wiping movement of the plates jinwardly, but merely serving to position the wipers at the edge of the heel seat and,

through the actuating connections 256, 258 and rod 228. to swing a hand lever 264. to which the rear end of the rod 228 is connected toward the operator of the machine and within convenient reacl'iing distance for subsequent operatiol'iot the wiper plates through this lever.

The present invention, as distinguished from earlier constructions, effects afconr plete wiping-over movement on the part of: the wiper plates coincidently with and through the movement of the plunger J30 to clamp the heel band. .Xccorclinglyl have. provided the wiper actuating lever 26% with a springmessed latch 266 pivotally mounted upon a link carried by the lever and arranged normally to engage its hooked end overthe projection on sleevei 2 3 i.

This latch, therefore, couples the wiper actuating rod 2281 to the heel, band clamping rod 230 through the connected lever 2645, so that when the knee lever 17 2 and cam 212 are actuated, the shoe is jacked upwardly and backwardly; the heel band is clamped against the heel end of the shoe, and the heel wiper plates are given a full inward and forward wiping movement with the lasting tacks.

To enable the wipers to be backed off and wiped in, independentlyof and without disturbing the heel. clampingplunger 230, a curved. latch releasing arm 270 (Figs. 1 and 2) ispivotally mounted on the wiper lever 26% with one end connected with the bifurcated rear end of latch 266 by a ball and socket joint and with itsother end positioned adjacent to the end of lever 26 1 so that when the operator grasps the lever to. operate the wipers, he likewise grasps and operates the arm 270 to release the latch.

Usually, during the lasting of. the heel end of the shoe, the heel rest is lifted up wardly by a foot treadle 272 and a connected rod 274 to press the edges of the upper against the wiper plates so as to compact the over-worked upper material against the insole, the treadle being latched in upper compressing position and being" subsequently released by actuation of. an auxiliary'foot treadle 276. The specific construction of. these parts, however, has no relation to the present invention. As shown, they "are intended to operate similarly to the last spindle operating treadle and latch releasing treadle of prior United States Patent No. 1,066,375, granted July 1, 1913.

After the edges of the upper have been wipedover and compacted, they are fastened to the insole, as previously described. As shown, the machine is equipped with a (tack hopper 278 operated by a belt from a surface 91 of pulley to feed tasks to a hand tacking tool as more fully described and illustrated by prior Patent No. 1,018,477.

In the use of the machine, the heel lasting carriage 3 is adjusted about its pivot 5, if

necessary, to correspond with the swing of the shoe selected for lasting. This shoe with. its last is then mounted on the last spindle G, and the toe end of the shoe is centered between thetoe wipers and the angular position of the shoe is adjusted, if

necessary, to position the toe and heel wipmg mechanisms symmetrically with relation to the longitudinal median lines of the forepart and heel part of the shoe and last. Then by means of the hand wheel 204 the heel post is moved rearwardly and upwardlv to bring the heel end'of the'shoe against the side faces of the last.

the heel clamping band 210 (as in F El) and in the plane of the heel wiper plates. The workman then presses the knee lever 172 to throw in the one cycle clutch, and through the cam shaft. to effect, the jacking operation previously described whereby the toe rest 4 is lifted to tip the shoe lmckwardlv into the heel band and the heel band is closed and the heel wipers givci'i a full wiping movement over the heel seal; through cam 212 and the operating connections prcviously dcscrilwd. swinging the wiper operating lever 26%- into position to be grasped by the workn'lan. The shoe is now ready for the wiping operatioi'is at the toe and for additional wiping operations at; the heel end. Before wiping, the hold-down is brought down against the insole and prop erly positioned relatively to its too end.

In lasting some shoes the automatic or power effected closing of the heel wipcrs adequately shapes the upper materials over the heel scat end of the shoe and no further lasting of these materials is required prior to tacking them. Other shoes. however, comprise upper materials which are so resistant that a repetition of the movement of the wipers is required for the purpose of adequately shaping the heel seat.

If such a shoe is being lasted. the workman will now swing the lever 264- backwardly and forwardly until the edge of the upper is wiped down and compacted on the heel seat of the shoe. the foot treadlc 272 usually being. depressed to elevate the last heel and compress the stock against the piper plates durin this operation. and being subscquentl y released. The wiper plates are then partially backed off and lasting tacks are inserted to fasten the overworked upper to the insole.

The toe lasting head is in lowered position at the beginning of the lasting cyclc. Thc wipers and toe clamping band, if a too clamping band is employed. are adjusted to the lateral swing and vertical inclination of the toe. the holddown 13:) is brought down into engagement with the toe cud ol the insole, the workman dcprcsscs one side of the double acting foot trcadle 10-1 to cause the screw 11. to be turned in the direction to raise the toe lasting head 8, and presses the wiper lever 36 inwardly to hold the edges of the wipers against the sides of the toe of the shoe as the lasting hcad rises. This head will havi a. lateral component of movement as previously described confornn ing to the inclination of the side faccscf the toe of the last so that the wipers will upwipe or conform the upper accurately to \Vhcn the too head reaches'the point in its upward movcment when the screw 11-1 cngagcs the stop block offset 113, the clutch sleeve 94.- will be automatically shifted to neutral position, stopping further upward movement of the toehead and positioning the toe wipers in theplane of the insole. These wipers may be advanced and backed off as many times asdesired to break down and wipe over the edges of the upper. Usually the treadle 7 up a have foundthat some operators, after of pressure to compact it.

becoming experienced, find that the mechanism herein provided for arresting the upwiping movement at the proper point is unnecessary and that they can work advantageously without it. it will therefore be understood that the present invention is not limited to the inclusion of astopping mechanism, except as definitely required by the claims. 1

The connections herein provided from the hold-down to the stop block 112 are. arranged to arrest upward movement of the toe head with the wipers positioned to wipe the upper over the insole with the re uisite degree Lsually, however, it is desirable toforce the wipers downwardly upon the overwiped stock for comressing or ironing down the upper material to form a satisfactory surface uponwhich to attach the sole or weltof the shoe bottom. Mechanical arrangements have been provided by which the machine'operator may augment the ironing down pressure which he was able to exert by the use of the double ended foot treadle shownin my prior patent. The presentinvention, however, relieves the operator from thisfatiguing work by providing power driven mechanism for forcing the wipers downwardly upon the overwiped upper. materials. This power movement is produced by depressing the heel or right liandend (Fig. l) of the treadle 104, thus shifting the clutch sleeve 94into position to drive bevel gear 82 and through screw 11 to cause the power to draw the toe lasting headdownwardly. It will be noted that this wiper depressing or ironing; down movement is transmitted through the] friction clutch surface of sleeve 94 and gear 82. The force with which these friction surfaces are held together is regulated by the pressure which the operator applies to the heel end of the treadle. The friction surfaces are li'urthermore so designed that only a predetermined amount of ironing down pressure will beobtained before such surfaces will slip. This provision avoids danger of breaking the machine or injuring the shoe by excessive pressure.

When the edge of the upper at the toe end of the shoe has been properly wiped over and compacted, it is temporarily fastened to the insole, by wiring in the case of a welt shoe, and by tacking in the case of a McKay shoe. Then the knee lever 150 is operated to release the hold-down, and the heel rest treadle is released. The knee lever 172 is next. operated to cause shaft 92 and cam shaft 196 to be rotated, lowering the toe rest, and releasing the latch of the heel lasting mechanism and the pressure against lever 222so that the connected spring which has been under tension reacts to cause the heel band to open, the pressure of lever 222 against lever 220 also imparting an impulse to the heel lasting mechanism to move it bodily lengthwise of the carriage 3. Coincidently with the release of the latch of the heel lasting mechanism' and through the same actuating mechanism, the latch on hand wheel 204 is released through suitable connections from said actuating mechanism so that the slide 198 and heel pin 6 with the last and shoe are held forwardly by the spring 206 while the heel lasting mechanism moves bodily away from the shoe and slide and lengthwise of the carriage 3. The connections from the actuating mechanism may conform (as shown in Figs. 1. and 3) to the connecting means illustrated and described in detail in Patent No. 1,188,616 of June 27, 1916, although other connections may be used if desired. 1

These nnjacking actions all occur in an instant and the workman, without any attention to the machine, may remove the lasted shoe and reach for an unlasted shoe while the toe head is lowering. This lowering action is effected automatically when the knee lever is operated to free the last and shoe from the end lasting mechanism as just described. The treadling causes the shaft 92 to be rotated, causing eccentric 156 to move the yoke 1'76 rearwardly and through spring 186 to shift the clutch sleeve 94 to lower the toe head which is automatically stopped when the rod 188 raises pawl finger 180. The lowering and stopping of. the toe head and the coincident release of the shoe and last from the heel end lasting means bya single actuation of a common power controlling means is particularly advantageous in that. it obviates the necessity of backing off the toe wiping mechanism by the lever 36 and hand wheel let and the subsequent actuation of the treadle 104 to lower the toe head by power. 1 Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
