LASTING MACHINE.

Application filed July 1, 1925.'- Serial No.40,782.

This invention relates to machines for last ing shoes, in the broad sense of applying shoe parts to lasts, and is especially applicable to the lasting of shoes comprising rubberized 01 rubber parts, although not wholly limited thereto.

Our general object is to provide an improved lasting machine of simplified and dependable construction. Further objects are to provide a machine readily adaptable for accurate operation upon either right or left shoes, and to reduce the number of parts necessary for the actuation of certain types of worlcmanipulating mechanisms as compared with machines heretofore known. Other, more detailed, objects will become manifest as the description proceeds.

General descm'ptz'on.

The machine comprises a bearing standard 10 formed with various bearings, guides and brackets for the moving parts and supporting an annular, fixed, supporting frame 11 for a set of upstanding gripper units surrounding the lasting position. The annular frame 11 is adapted to permit vertical reciprocation of a last-support 13 to carry a bare last from lasting position, where the last is received, to a lower position, out of the way of the gripper units, and then .to return the last to lastin I into .an upper meanw ile mounted in the gripper units. The gripper units are adaptposition to force it ed collectively to receive the sole margin of the upper between their gripper jaws and to position it therein by the retractive move ment of yieldingly closed positioning jaws which lightly draw the margin into the gripper jaws and slide upon the margin in further movement after the margin has been stopped at a determinate position in the ripper-jaws. The said gripper units are a apted to anchor the uppers, margin, as thus positioned, while the last is forced into the upper, and then to fold inward the uppers margin and stick it onto the sole face of the last, or an insole thereon.

Two annular actuating frames 14 and 15, surrounding the lasting position, are adapted concurrently to actuate the gripper units throughout the machines entire cycle of operations, and suitable drive mechanism is provided for moving the last-support and the two actuating frames in determinate time relation throughout two successive movements constituting the cycle, automatically stopping at the end of each movement.

The gripper units are pivotally mounted upon the fixed frame 11, to tilt from and toward the last in the lasting operation, and

adjusting means is provided for concurrently tlltingcertain of the gripper units at opposite sides of the'last, by modifying their connection to the actuating frame 15, so as to change the configuration defined by their gripper jaws and thus to adapt the machine to operate upon right or left shoes alternatively.

Gfipper units.

20. The upper end of each slot 18 is closed by a cross-pin 21 to limit upward movement of the jaw carrier. I

at their lower ends, below the spacer plate -16 ,-by a pin which projects at each side of the pair of slide bars, itsrespective end portions being mounted in slots "termed in therespective forks of a bifurcated lever 26 which is pivoted at 27 upon -a bracket 28secured to the side plates 16", the said flQVGl' 26 being adapted to open and close the gripper 23 with relation to their mates 22.

I The lever 26 is constantly urged toward ij aw-opening:positionby a compression spring 29 interposed between its outer arm and the horizontal. arm ioxor the jaw carrier. 'F or turning ;it toward ,rjaw closing position, against the force of said spring, its outer arm is formed with 'an oblique cam face 30 adapted to 'be abutted by a cam shoulder formed on a C-shapedlever 31 which has a bi furcatecl end-straddling the pairof side plates 16? and pivoted thereto at 32.

Pivoted on the other end of the lever 31 at 33 is the lower jaw member 3410i a pair of sliding, upper-position jaws adapted to draw themar-gin ofth'e upper into thegripper jaws '22, 23, the upper jaw 'member 35 of said {pair being hinged to the lower jaw 34: zit-36'. The jaws 34, 35 are slid'ably mounted between the twingripper jaws 22 and between the twin gripper ja ws 23, and the lower sliding jaw 34 is adapted to 'be sup- ;po-rted by and to run upon a roller 37 journalled bet-Ween'theside :plates 16 upon apin 38 mounted in said side plates and having pivoted upon its end portions the respective carsofa double plate lever 39 whichis formed with an upstanding guide finger 40 for guiding the margin of the shoe upper into the jaw assembly. The side plates of said linger are formed with respective aligned notches Ll adapted to admit the margin into the jaws 22, 23, the wallso t said notches, at their angles, scrvlng asabutments for the uppers margln, to stop the latter as it is drawn into the jaws 22, 23 by the sliding jaws 3e, 35,

and so to position the margin accurately in the gripper aws prior to the'closing of the l atter.

1 Turnlng movement of the lever 39 about its, pivot 38 toward the lasting position is limited by shoulders 12, 42 formed on the adjacent faces of the plates ofthe guide finger "40 and adapted to abut the upper end faces oi the respectiveside'plates 16 of the jaw carrier. For yieldingly urging the lever 39 toward that stopped position and for opening and closing the sliding jaws 34, 35 and urg ng them toward their pro ected, open position, an L-shapeddouble plate dog 43 has ing jaws 32;, and having journalljed loctween them at their elbow a roller 4L5 adapt ed to run upon the upper face of the slidmg jaw 35, yieldingly to urge the aw toward closed position, under force of the spring 4.4,

throughout the greater art of the range of sliding movement of t re aws 34;, 35, and adapted to engage a projection 46 upon the hub of the jaw 35 and thereby to open said jaw as the'slidin'g jaws arrive at the limit o f their projective movement.

For tiiirnin-g the fi-shaped lever 31 about its 'pivot 32, against the force of the spring i l, to retract the sliding jaws 8 1-, 85, and to cause them to close lightly upon the upper 'an d'd aw its margin into the gripper jaws, a roller 47 adapted to bear upon the upper edge face oi the lever 31isjournalledupon a bar 48 pivoted at 49 upon -a bracket 50 secured to the-actuating frame 14, said/bar being yieldingly held upward against an adjusting screw 51 mounted in said frame by a C-shaped iinge sp'ring 52 connecting the bar with its bracket. The C-shaped lever 31 fin-med with an arci ate margin 58 for coaction with the roller 47, the lever 31 being so formed that, when it is at the limit of its jaw closing movement, the said an -cuate margin will be concentric with the pivot 17 of the jaw carrier 16, so that the gripper assembly may be tiltedftoward the -lastin-g position while the roller 47, running upon the farcuate face 53 of the lever, continues to hold the gripper jaws closed and thesliding, upper-positioning j retracted For yieldingly urging each-j aw carrier'16 to tilt toward 'the'last', the outer end o'i't' its horizontal arm. 16", as to the gripper units about the heel and lLOG'OiE the last, which do not require special adjustment for right and leftshoes, has hinged thereto at 54: a-downwardly extending spring rod 55 projecting iiloosely'through an aperture 56 in the actuating frame 15, shown clearly in Fig.7,a'nd compression spring 57 is mounted upon said rod between a shoulder 58 formed thereon and the actuating frame 15. For positively tilting the jaw-earner outward, a pull rod 59 is hinged to the jaw carriers horizontal arm 16" at 60 (Fig. 7), extends downwardly U through an adjustable bushing 61 screwed into theactuating frame 15, and has*a retaining V I nut 62 on its lower end, below the bushing and abuttmgthe latter under'the force of the spring 57, the bushing 61'being adapted to be v screwed upward or downward to lengthen or shorten this positive link connection of the actuating frame with the jaw-carrier arm 16*.

In order that the similar connections of the jaw-carrier arms 16 along'each side of the last may be quickly and concurrently adjusted to adaptthe machine for right or left shoes, the spring rods of each of these awcarriers extend through a countersunk aper ture in a block 63 overlying the actuating frame 15 (Figs. 4- and and seeured to the tops of a pair of vertical guide sten i's 64, 64 slidably mounted in apertures in the frame 15, there being one of these blocks 68 at each side of the last, and the compression spring 57 on the rod 55 seats in the countersink of the block. The pull rod 59 of each of these gripper units extends loosely through asleeve 65 which is adj ustably secured in the block 63 by a set screw 66, and slidably extends downward through an aperture in the frame 15. The pull rod 59 has its upper end screwed into a clevis member 67 hinged to the jaw carrier arm 16 at 68, and the lower end of the pull rod is formed with a knurled head 69 held against the lower end of the sleeve 65 by the force of the spring 57.

For raising the block 63 at one side of the machine and concurrently lowering the block 63 at the other side of the machine, to tilt one group of aw carriers toward the last and the other away from the last for right and left adjustment, while the frame 15 remains stationary, each of the guide stems 61- of the blocks 63 is slotted at its lower end, the slot being traversed by a cross pin 70 mounted in an oblique slot 71 formed in a cam plate 72 projecting downward from a transverse arm 73 mounted for sliding movement in a suitable dove-tail guide 73 (Fig. 1) formed in the lower face of the actuating frame 15, the several arms 73 being secured to an annular frame 74 connected by a link 75 (Fig. 6) with a bell crank 76 having a handle 77 (Fig. 1) for sliding the annular frame 7 4 and its arms 73 transversely of the machine and thus cause the cam plates 72 to raise one pair of the blocks 63 while lowering the other. Respective latching devices 78, 78, (Fig. 1) are mounted on the under face of the frame 15 and are adapted to engage the bell crank 76 to hold the parts in one or the other of the positions of right and left adjustment.

head 82, said cross head has hinged thereto at 84 a connecting rod 85 whichcxtends down ward through a block 86 .(Fig. 1) with a sliding fit, said connecting rod being provided with a pair of nuts 87, 88 bearing respectively upon the .under face of the block and upon the upper end of a compression spring 89 in tcrposed between the upper nut 88 and the block, for adjusting its effective length. The block 86 is formed with opposite trunnions 90, 90 mounted in the ends of the parallel arms 91, 91 of a double lever (Fig. 1) which has a cam roller 92 (Fig. 2) journaled between itsarms atan intermediate part thereof and adapted to run upon the periphery of a cam disk 93 (Figs. 1 and 2) secured upon a shaft 94 which is journaled; in bearing brackets 94 182 and 138, the rear end of the lever 91being pivoted at 95 (Fig. 2) in the top of suitable brackets 96, 96 rising, from the base of the standard 10. i

The upper face ofthe last support 13 is so formed as to give the last a terward tilt. as will be clear upon reference to Fig.8, so that the'rein'forced portion'of the upper atthe heel of the last will be pulled to a comparatively close-in position and will not require excessive contracting or fulling of this relatively thick and stiff portion of the upper in applying its margin to the insole, the gripper units being so positioned and proportioned as to pull the uppers margin to appropriate positions corresponding to the tilt'of the last, as will be apparent upon reference to Fig. 1.

Such tilting of the last also results in the pulling of the upper at the toe of the last to a comparatively out-standing position, so that the fabric is not pulled too abruptly down ward over the point of the toe of the last and consequently does not bind excessively by friction againstthe last at that position; I

The inclined position of the set of gripper units and the last, with relation to their direction of relative movement, which movement of the last is nonperpendicular to the sole face of the last, the last moving with its heel portion somewhat in advance of its too portion, thus improves the operation at both the toe and the heel of the last.

Drives for actuating frames.

The higher actuating frame 14 is supported upon two pairs of slide bars 97,97 which extend slidably through the lower actuating frame 15 and through guide brackets 98, 99 formed on the standard 10, the lower ends of the bars of each pair being connected by a .head 100 which is connected by alink 101 with a lever 102 secured to a rock shaft .103 journaled in the brackets 132, 138. For rocking the shaft 103 a rocker arm 104' (Figs. 1, 2 and 5) is secured thereto and is'provided at its outer end with a cam roller 105 mounted in a cam groove 106 formed in the side face of a cam disk-107 secured uponlthe' shaft 94.

The lower actuating frame 15 is supported and adapted to be raised and lowered by two HIU pairs of vertical slide bars 108, 10.8 slidably mounted in suitable apertures in the brackets 98 and'99 and the bars :of each pair are connected at a position between the said brackets by a cross member 109 retained in place by collars 110, 110 secured upon the bars. Each of the said cross members is formed at its forward end with a gear segment 111 with which is meshed a oinion 112 secured upon a hollow shaft 113 (liig. 5') rotatably mounted in the outer ends of arms 114., 1.14 which are pivoted as at 115 (Fig. .2) to the respective cross mem bers 109, the pivot 115 being concentric with the gear segment 111, so that the pinion 112 may run upon the gear segment in mesh there with.

Extending through the hollow shaft 113 and through arms 11.6, 116 pivoted to the respective cross members 1 09 at the axis 115 is :a clamping rod 117 provided with a hand wheel 118 threaded upon one end thereof, for clamping the arms 11:6 against the pinions 112 and the ends of the hollow shaft 113 to pre vent rotation of the pinions and thus to secure the latter in adjusted positions upon the gear segments 111. A hand wheel 119 is secured upon the hollow shaft 113 for running the pinions 1112 upon the gear segments, to adjust the arms 114, 11 6 with relation to the cross members 1 09. A scale 11 9 is secured upon the hollow shaft 113 and is associated with an indicator 119 secured upon one of the arms 114 (Figs. l and '5) for indicating the adjustment.

Links 120, 120 are pivoted tothe respective arms 114, 116 as at 121, Figure 2, and as at 122 are pivoted to respective arms 128, 123 secured to a rock shaft 124 journa led in the standard 10 and provided with a rocker arm 125 which has at its outer, lower end, a cam roller 126 mounted in a cam groove 127 formed in the side face of a cam disk 128 -Secur-ed upon the shaft 94.

For driving the shaft 94 and thereby raising and lowering the last-support and the actuating frames 14 and 1-5 in timed relation the said shaftv 94 has secured thereon a gear 129 meshed with. a pinion 130 secured upon a hollow spindle 131- which is 'journaled in the bearing bracket 13-2 Figs. "3 and 5) and is formed integrally with abrake drum 133 and a j aw-clutch member 134, said aw clutch member being adapted to mate with a awclutch member 135 slidably keyed upon a shaft 136 which is journalcd in the brackets 96, 96, 138 rising from the base of the stand ard 10, the shaft 136 rotatably extending into an anti-friction bushing 139 (Fig. 3 mount-ed in the hollow spindle 131, and said slraft'1'36 being provided with a drive pulley 136 and adrive belt 186 thereon.

For engaging and disengaging the jawclutch member 135 with its mate 184 the member 1 35 is provided with a shipper lever 140 secured upon a shaft141 (Figs. 2 and 3).

shoulder 149 formed upon an upstanding arm 150 of a two armed lever pivoted upon a stud 1'51 projecting from the machine frame. The lowerarrm 1.52 of the said lever is connected by a pull rod 153 with a treadle 154 (Figs. 1 and 5) at the front of the machine for unlatching the arm 150 from the arm 148 to stop the machine in emergency. To prevent overrunning of the machine a brake arm 155 is-secured to the rock shaft 141 and provided at its outer end with a brake shoe 156 "adapted to coact with the brake drum 133 under the force of the spring 143, whenever the latter is oer-,

mitted to disengage the clutch.

For automatically stopping the machine at the end of each of the two movements of the cycle, the cam disk 128 is provided on its side face with dogs 157, 158 adapted to engage a tripper arm 159 extending from the hub of the latching arm 150 and connected with the base of the machine by a pull spring 160 adapted to urge the arm 150 toward latching position.

' Operation.

The machine is shown in Figs. 1,2, 5 and 6 with parts in the positions which they oc- .cupy as the machine is stopped at the end of the complete cycle of operations, the dog 157 being in contact with the tripper arm 159 to unlatch the clutch and stop the machine. It will be observed that when the machine stops, the cam roller 92 (Fig. 2) is upon the second highest reach A of its cam 93 and that consequently the last-support is .at approximately the elevated position of Fig. '6. The cam roller 105 is in the short-radius portion B of its cam groove 196 and consequently the actuating frame14 is at its lowermost position, holding the sliding jaws 84, 235 closed and ret-racted. The cam roller 126 is still within the short-radius reach C of its cam groove 127, so that the actuating frame 15 is almost its lowest posit-ion, with the jaw-carriers still tilted sufliciently away from the last-support to permit the mounting of a last thereon.

lVith the parts in these positions an insole 79 and last 80 are placed upon the last supportlil as shown in F 6. The machine being thrown in gear by the pressing of the treadle 147 the arm 148 latchcs upon the ar-m' 150 and the shaft 94 is driven clockwise as clutch in engagement a viewed in Fig. 2 until the dog 158 strikes the.

tripper arm 159 and thereby brings the machine to a stop.

During this movement the last support with the last and insole thereon are lowered to the position of ig. 7 the cam roller 92 passing onto the short-radius reach of its cam 93. i-it the same time the actuating frame 14 is raised the cam roller 105 passing into the long-ra dius reach E of its cam groove 7 106, and asthe machine is brought to a stop.

by the dog 158 the sliding jaws 34, 35 are held projected as in Fig. 7 by the spring 44 and the upper sliding jaw 35 is held open, as there shown, by the roller 45 in engagement vith the projection 46 on the hub of said jaw, the spring 44 also holding the guide finger 40 in stopped position against the upper end races of the gripper jaws 22.

In this movement the lower actuating frame 15 is slightly raised, the cam roller 126 s (Fig. 2) passing into the reach F of its cam groove, this slight upward movement of the frame 15 permitting the jaw-carriers to tilt slightly toward lasting position for reception of a conoidal upper 163 to be presented thereto as shown in Fig. 7. At this time, with the machine stopped by the dog 158, the studs 17 are in the lower ends of their slots :18, as

shown in Fig. 7, the pull rod 59 being under ension and the horizontal arm 16 of each jaw-carrier being urged about the pivot 60 by the compression spring 57. At this time alsothe lower gripper jaw 23 is held open by the spring 29, the C-shaped lever31 being held out of contact with thelever by the pull spring 44, as shown in Fig.

lVith the gripper units at the heel and toe of thelastthus held in the position of Fig.-

7, and the gripper units at the sides of the last being held in similar positions, the upper 163is placed upon the set of lower sliding jaws 34 as shown in Fig.7, and the machine is again started, by depressing the treadle 147,,

and continues to be drivenuntil the dog 157 again strikes the tripper lever 159 to stop the machine. '7 j I Atthe beginning of this second movement of the cycle the lower actuating frame 15is slightly raised by thecam roller 126 passing up the short incline Gof its caingroove, to tilt the jaw carriers slightly further toward the lasting position so as to cause the walls I of the notches 41. to definea figure having substantially the same perimerter as the heel margin of the nppergthe gripper units then being held to this configuration while the cam roller 126 is on the reach H of its cam grooves Immediately after this short inward tilting of the gripper units, theactuatingframe 14 is lowered, the cam roller 1.05 passing down the incline I of its groove, and this lowering of the frame 14 causes the rollers 47 to bear upon the arcuate edge faces 53 of the C-- shaped levers 31, turning the latter about their pivots 32, against the force of the pull springs 44 and thereby ca usingthe sliding jaws 34,35 to be retracted past the gripper jaws 22, 23, the upper. sliding jaw being lightly closed by the cam roller at the beginning of their retra'ctive movement and being held lightly closed by the said cam roller as the sliding jawscontinue to heretracted, so that the sliding jaws draw the Inargm of the'upper into the gripperjaws 22, 23- until the edged face of the margin abuts the walls ofthe notches 41 in the fingers 40 and is positioned thereby, as shown in F 8, the I sliding jaws 34, 35 then slipping uponthe fabric margin of the upper throughout the rest of theirret-ractive movement,to the position of Fig. 9.

Near the end of this retractive movement of the jaws 34, 35, the C-shapedlever 31 contacts the lever 30 as shownin Fig. 9, and turns the latter about its pivot 27, against the force of the spring 29, to force upward the slide bars 24 and thereby close the'lower gripper jaws 23 ilipon the fabric, against the jaws 22.,

Meanwhile the last support 13 is elevated by the cam roller 92 passing up the incline J ef its cam 93, and shortly after the gripper aws are firmly closed upon the uppers mar-;

gin the last arrives at its uppermost position and is forced into the upper while the latter is, held by the grippers.

As soon as the last has thus been forced fully into, the upper and while it remains in that position, the cam roller 92 running on the concentric portion K of its cam 93, thelower actuating frame 15 is furtherraised by the cam roller 126 passing into the long-radius portion L of its. groove, whereby the gripper units are tilted toward the last'until they carry the margin of the upper against the last support 13, as shown in Fig. 10, the guidefingers .40

pressing the upper against the'c'ornerof the last, as there shown, but yielding to permit the gripper jaws to carry the margin under] the last, the said gripper jaws being held closed and the sliding jaws being held retracted during the inward tiltingof the jaw car riers by the rollers 47 running upon the, arouate margins of the levers 31. r

The actuating frame '14 is then raised by the cam roller passing into the longradius reach Mof its groove, which first permits the springs 57 to raise the jaw-carriers to carry the uppersmargin against the insole 7 9 and stick it thereto, as shown in Fig. 11, the upper being cemented along its margin as shown at 164', (Figs. 7, 8 and 9), and the jawshapedlevers 311 from the respective jaw-closing levers 26,. thus permitting the springs 29 to open; the gripperjaws and release the un-, attach-ed portion of the uppers margin therefrom, and projecting the sliding jaws 34, 35. During-the first part of theprojective movemerit of-the said sliding jaws the upperja-w 35 slides inwardly upon the unattached portion ot'the uppersmargin-previously heldby' the gripper'jaws-and progressively sticks it to the insole, the-work being held down by hand,

and the jaws 34, 35 together, sliding over the edge of the last support 13', lift the last'therefrom; As the sliding jaws.approach the limit of th' eir projective movement the rollers l5 by contact with the upper jaws hub projections e6 cause the jaws 35 to lift from the jaws 34" and collectively to support the work ap-,

proximately'as shown in Fig. 12', the gripper units meanwhile being'tilted: far outward and returned to their lowermost positions in the slotslfi'by the cam roller 126 passing down the incline of its groove and causing the jaws I 35, to slide outward in pressing relation to the marginof the-upper, so that the upper is ironed out toward the edge of the insole froin-itsgcemented' zone, after-whi'chthe frame onto the pOrtionA oi slightlyshorter radius,

so that the support is slightly lowered to a position such that the jaw-carriers may serve as gages for the purpose of positioning the next insole and last. The operation as described is then repeated..

Adjustment'ofthe machine to change from right to left shoes or. vice versa is readily. ef-

iec-ted' by simply turning the bell-crank handle 7 7 from one of the latching devices 78 to the other, as will be readily understood upon reference to the above description of the adjusting devices.

Theemployment of means such as the levers 26,.actuat'ed by the jaw-retracting levers 81', forclosing the gripper jaws, eliminates the 7 need; of. one, of the three actuating. frames heretofore employed in machines v of generally similar character, and permits the use of simple mechanism for right-and-leit adjustment. The reduction in v the number of actuating frames also permits the simplification of driving means.

mum

t'wo successive-movements with the last-su port starting the cycle from its uppermost position, permits a single operator c'onvenv iently to mount boththe last and the upper in the machineand permits a great reduction in" the height of the machine as compared with prior constructions in which the last-support required to be'lowered clear of the actuatingframes for the introduction of the last thereto, below the frames, fromtheside of the machine. Other and more detailed advantages will bem anifest.v

Our invention is susceptibleoi modification within its scope, and we do not wholly limit our claims to the specific construct-ion shown.

5. A lasting machine comprising a set of stock anchoring units defining a lasting position and pivoted on axes approximately parallel to the adjacent part of the sole edge of the last to tilt toward a last held in said position to carry the margin of an upper inward about the sole margin of the last, actuating means for concurrently so tilting said units, and means for concurrently modifying the connections of said actuating means to cer tain of said units so as to give them initial angular positions with relation to their pivots such as to adapt them for right or left shoes alternatively, the tilting means compri, an actuating frame structure common to the units and link connections from said frame structure to the units, certain said'linkconnections comprising cam'n'icans for vary ing their effective lengths.

6. A lasting machine comprising a set 01" L-shaped jaw carriers defining a lasting position and pivoted at their elbows to tilt from and toward a last held in said position, the several carriers comprising jaw-carrying arms extending in the same general direction toward the last and actuating arms extending outward from the set, an actuating frame structure common to the units, for tilting them from and toward the last, link connections from said frame structure to the several units, certain of said connections comprising cam means for varying heir eli'ective lengths, and interconnected means for concurrently actuating the said cam means oppositely at different parts of the set to adjust the machine ior right or left shoes alternatively.

7. A lasting machine comprising a set of jaw carriers, a pair of gripper aws mounted on each carrier, stock-positioning means mounted on each carrier and having a projective and retractive movement for receiving the solemargin of an upper and drawing it into the gripper-jaws, contact actuating means con'iprising a single contact member for each jaw carrier adapted to actuate the stock-peeitiouing means and then to close the gripper jaws in a single moven'ient,-tl1e set of gripper jaws being unobstructed for the tree reception an upper from an axial direction with reiationto the set, a movably mounted support adapted to receive a last at the lasting position, withdraw it soleward therefrom and then to return it to the lasting position to force it into an upper held by the jaws, means for moving thegripper jaws to apply the sole margin of the upper to the last, and means for actuating the gripper units and the last support in successive cycles 01 two movements each, said means being adapted automatically to stop the machine at the end of the first movement with the lastsupport withdrawn from lasting position and the gripper jaws open, and at the end of the second movement with the last-support in lasting position and the stock-positioning means and the gripper jaws so withdrawn from the lasting position as to permit the free reception ot a last by the last-support.

8. A lasting machine comprising a set of stock-anchoring unit-s adapted concurrently to receive and anchor the sole margin of a shoe upper, a last-support for carrying a last into an upper so heldymeans for actuating said units to carry the uppers margm inward about the sole-edge ot' the last, and means torso actuating the several elements in success1 ve cycles comprising two movements each that at the end of one movement the last support is adjacent the lasting position and the stock-anchoring units are cleared away for the reception of a last by the last-support and at the end of another movement the stock-anchoring units are in position'for the reception.

of an upper and the last-support iswithdrawn from lasting position.

9. A lasting machine comprising last manipulating means, upper manipulating means, and means for so actuating the two said means concurrently-in cycles comprising two movements each that at the end of one movement the last-manipulating means is positioned to receive a last. approximately at lasting position and at the end of another movement the upper manipulating means is positioned to receive an upper approximately at lasting position and the last manipulating means is withdrawn therefrom, the last-Inanipulating means and the upper-manipulating means being adapted in one part of the cycle to coact to pull the upper onto the last.

10. A lasting machine as defined in claim 9 in which the upper-manipulating means member movably mounted on each carrier and adapted in one part of its range of movement to close and retract the upper-positioning jaws and by further movement to close said gripper jaws, and means for so actuating the several said elements as to present the last support for the reception of a last approximately at lasting position while holding the upper-positioning jaws retracted and the carrier'assemblies clear of the lasting position, then to withdraw the last support and open the gripper aws and upper-positioning jaws for the reception of the upper, then to actuate the said jaws to anchor the upper and to return the last support to force the last into the upper, and then to actuate the carriers to pull I the upper inward about the sole ot the last.

12. A 1astin machine com Jrisin i a last- 6 l O support and co-operatlvely associated there with a 121w earrler, a pan otgrlpper a-ws mounted thereon, stock-positioning means 13. A lasting machine comprising a last support and co-operatively associated there with a jaw carrier, a gripper jaw fixedly mounted thereon, a mate for said gripper jaw movahly mounted on said carrier, a pair of stoclepositioni-ng jaws mounted on'said carrier tor p1o1eet1ve and retraetlve movement past the said gripper-jaws, a lever pivoted onsaid carrier and having pivotalconnection to said stock-pos1tromng aws for imparting to them: their pro ectve and retractrvemovement, and means adapted by contact of said lever to close the said gripper-jawsnear the end of its retraetive movement.

14. A lasting machine comprising a lastsupport and cooperatively associated therewith a jmv support, a pair of gripper jaws:
