illustrated as embodied disclosed in the above- Since the invention is in a machine of the type Imentioned LettersPatent, only such features of its general organization as it is necessary to refer the invention will be It will be understood that machines of the illustrated typeare generally used for lasting shoes along their opposite sides and, sometimes also around the t'o'e'ends, each shoe on its last being supported. in the hands of the operator and 'sitions for the operation of the machine. To

assist in determining the proper relation of the shoe to the lasting instrumentalities, the machine is provided with .the usual shoe bottom rest 29 (Fig.l) arranged to engage the outer faceof the insole, and with two edge gages 22 and 28 arranged 'to be used alternatively in operating upon different portions of the shoe bottom. The thin edge gage 22 is secured to a bracket 24 fast on the head 25 of themachine and is arranged to engage the side of the shoe at or near the edge of the insole to guide it in lasting the opposite ball portions, and the thick edge gage 28 (adapted for use) is used to support the shoe in lasting around the to end and also at the opposite sides in locations at or breast line. The edge 32 by meansof in vertical section of presented successively in different po-.

draw movements are imparted by mechanism .t and is'released by the cam iii) '45 in adjusted position.

there is provided a wiper 35 carried by a slide 38 which is movable along a horizontal guideway in the head 26 of the machine and to which there is imparted one complete reciprocation in each cycle of operations of the machine to cause the wiper 36 to wipe the marginal portion of the upper inwardly over the outer face of the insole and to withdraw. A staple driver is fastened to a driver bar 42 which, as more fully shown and described in the prior Letters Patent, is movable .in a guideway formed in a carrier (not; herein shown) journaled forswinging movementin trunnions formed in a bracket fast to the head 26. In

.the illustrated machinethe slide 38 has adjustablysecured thereto a block which serves as an abutment (Figs. 2 and 6) and which is arranged to engage an abutm ent ifi on the driver bar 42 near the end of the forwardmovement of the slide as and to swing the driver bar 42 and the driver diliwith it, thusalining the driver with a staple-guiding passageway in the wiper 35 and maintaining such alinement during the remainder of the overwiping operation. The block 44 carvries an adjustable screw 45that engages a por tion of the slide 33 and by means of which the block may be adjusted relatively tothe slide, the block being then locked in adjusted position by means 'of a bolt 41 carried by the slide andextending throughan elongated slot 49 in the block, a lock-nut 5| being provided for holding the screw It will be understood that the driver bar 42 is raised by a cam .(not shown) against the resistance of a torsion spring 7 to theaction of the spring-for the staple-inserting operation after the completion of the forward movement of the wiper 36 and the slide 38.

It willbe'understood that with the outside former in its lowermost position there .is provided a substantially continuous passage .through'it' and through the :wiper 38 for the staple and the driver 40 and that the' staple and driver passage are moved into alinement with thedriver 40 the position of which is determined by engagement of the abutment on the slide 38 with the abutment 46 on the driver bar 42. At-the end of. the over-wiping operation, as previously explained, the driver; 40 is released to the action of its operating spring forthe insertion of a staple which is driven through the over-wiped margin of the upper and through the insole, theends ofits legs being clinched on the iron plate on the bottom of the last. The means for feeding the wire to form the staples may be i and preferably is substantiallythe same as that fully shown and described in'Letters PatentNo. 1,731,853 granted October 15, 1929 upon anapplication. of George Goddu and need not be described herein in detail. Briefly stated, the wire is led from a reel and idler (notshowml down wardly between feed wheels I58 and I60 (Fig. 3)

and thence through a flexible tube I62 and a sleeve or quill 154 (Fig. '1) to the wire-guiding nozzle 14. The feed wheel 158 is operated by a ratchet and pawl mechanism I66 (Fig. 3) through an adjustable link I68 and a bell-crank lever I10 provided with a roll I12 (Figs. 1 andj3) en- :1 I gaged by a cam wheel I14 fast on a cam shaft wheel I14 (Fig. 3). Fast, on the cam shaft I16 is a bevel gear I88 that meshes with a'smaller bevel gear I90 secured to the lower end of a'vertical shaft I82 which is rotatably mounted in a bearing in the head 26 and at its upper end'is geared to the main camshaft 12'of the machine. The construction is such that the cam shaft I18 is rotated through 180 for one complete move ment of rotation of the main cam shaft 12 in each cycle of operations of the machine, thecam I86 being so shaped that the bell-crank lever I10 is first swung in a clockwise direction (Fig. 3) by the action of the spring I64 on the rock shaft I82 substantially at the beginning of each cycle of operations of the machine and before the main slide 38 begins its forward movement, after which'the bell-crank lever. I10 sis swung reversely by the cam I86 to its initial starting Itwill be understood that clockwise will act through the ratchet and pawl device I66 to rotate the feed wheel I58to feed a length of wire between the insidepand outside formers of the machine, v

In the machine herein shown there is provided an adjustable stoppillustrated as :ascrew I94, which acts by engagement with an arm I98 on the bell-crank lever I10 to limit the extent of clockabove-mentioned bracket 88.

wise swinging movement 'of the bell-crank lever (Fig. 3) under theinfluence of the spring I84, thus stopping the operation of the feed wheel I58 when a predetermined length of wire is fed into position to be acted upon by the inside and outside formers of the machine. Itgwill be understood that by varying the positionof the adjustable stop screw I84 theleiitent of clockwise'swingingmovement imparted to the bell-crank lever I18 may be varied as'desired to vary the length of the wire fedto form a staple. As herein shown, the adjustable screw I84 is carried by a plunger I98 which is vertically movable in a recess in the bracket. I18, a lock nut 288'being provided for holding the screw I94 in adjustedposition relatively to the plunger. The plunger I98 rests on the peripheral edge face 282. of a segment 204 that is pinned to theleft-hand end portion of a shaft 288 which is mounted in a bearing in the The peripheral edge face 282 of the segment 284 is eccentric to the axis of the shaft 288 (Fig, l) and, in order that the segment may be rotated quickly to vary the heightwise pcsitionlof the plunger I98 and n the stop screw I94, and thus torvarythe length of wire fed to form the staples and consequently the lengthsof the staples, for operating upon different portions of-the same shoe, there is fastto the right-hand end-portion of the shaft 206 a device comprising a hand lever-288 (Figs. 2 and 3). Itwill be understood that/a finer adjustmentof the lengthof wire fed may be made by adjustment of 'thescrew I94 relatively to the plunger I98. For determining-the properlimits of movement of the handlever 288 in opposite irections to vary the position of the adjustable stop I94 and thereby to control the lengths of feed of the .wire in accordance with the desired lengths ofrthe staples to be formed in operating upon different portions of the same shoe, there are provided stops 2I4, 2I5 (Fig. 2) adjustably secured in a curved guideway 2E6 formed in a bracket member 2I8 which is secured to the bracket 89 by screws 2I9. a 7

As previously pointed out, the stationary cutter or' wire-guiding nozzle 14 (Figs. 3 and 10) is carried by a bracket 16 on which is slidably mounted the movable cutter 84. 'The bracket 16 isadjustable laterally of the slide 88 on the guideway 18 (Figs. 1 and 4) formed on the bracket 89 and pivotally connected to the bracket is a lever 220 (Fig. 4) provided with an upwardly extending arm which is, forked to straddle a pin 222 projecting from the bracket 16 and with a downwardly extending arm carrying a pin 224. The

pin 224 is arranged to extendinto a peripheral cam slot 226 formed in the segment 284, The shape of the cam slot 226 is such that, in all positions of adjustment of the segment 284 and the adjustable stop I94 to vary the length of wire fed to form the staples, the stationary and movable cutters 14 and- 84 will be positioned in proper relation to the inside and outside formers of the machine to insure that the legs of each staple when formed from each severed piece of wire will be of substantially the same length.

In the use of the illustrated machine for 1asting shoes of the through-and-through sewed type, it is contemplated that staples will be formed of sufficient length to insure that the ends of their legs will penetrate entirely through the insole but only far enough to cause a slight clinching of the ends of the legs'on the metal plate P (Fig. 15) on the bottom of the last in the driving operation, thus insuring against any danger of :injury to theifoot of the wearer of :the shoe such as' mig'ht occur if excessively long r-staple's im properly clinchedwere used. Since-the upper materials at the toe and heel ends are ofgreat-er thickness than along the sides of the shank and ball portions or" the shoe because .0f.-the. added thickness of the toe stiffener-around'the'toe end and the counter around the heel end, :it will be necessary for the operator to vary the adjusted position of the stop 5-94 so-that the desired lengths of staples will be formed foroperating upon these differentlportions of the shoe. By adjustment-of the stops 2M and 215 alon'gthe curved guideway M6 the lengths of the 'staplesjformed for use'inoperating upon diiferent portions of .the shoe'may be varied and determined as desired In the illustrated construction, means-is ,pro-

'vided for swinging the device "or handlever 2% between the limitsdetermined by the adjustable stops 2M, H5 in response to the movements'cf the edge gage 23 into andgout of operativelposi tion. As shown particularly-in Fig.2, there is pivotally connected to the ,edge'gage 28 arc-d 2-2 that extends rearwardly througha stud-231i which is pivotally connected to the device-hi8. Mounted on the rod 228 are adjustable collars 3-32 ,13'4 that maybe secured in adjusted position on the nod by set screws The construction is such'that as the edge gage 23 is moved'forwardlytoits operative position the collar 232 will act by engagement initial inoperative position would cause-thead justable collar on the rod' 223 to en-gagethe stud 233 and to swing the device ifi8j reversely into the position determined by the adjustable stop 25 3-. As previously mentioned, it will be understood that the stops 2l4 vand;2i 5 willbe adjusted along the curved guideway ZlSso as t o vary the adjusted position of the 'stop-screw l94 .to control the lengths of feedofrthe wire in accordance with the desired lengthsofthe staples to be formedin operating upon the different portions of the shoe bottom. Since it is; necessary for the operator to move the edge gage .23 forwardly to its operative position in lasting around the toeend of the shoe and at-the. oppositesides thereofin locations at or rearwardly of its heel breast line,wand to movethe edge gage toiits'rearward inoperative positionin lasting along the sides of the shank and ball portions of tho s hoe,

the means" thus provided 'for' controlling the lengths of fastening material fedto fornifthe staples in response to" the movements o'f'the edge gage 28 not only avoid the necessity for the operator-tomake a"scparate adjustment of the stop operating uponeach differentp'ort'ion of the shoe bottom but insure that a staple of the proper lengthiwill be formed land d'rlvengi'n each location. It willlbe understood that the collars 2.32 and'234fwill beadjustedfon'thero'd 228; in pro'per'relation to the stud '2 ?"l"so"as"to causethe device 283 to be swung between 'the limits determined by the stops '2 i4. and '25 without limiting the movementsof the edge gage "28 into and out of operative position.--

Thesh-ape of the earn 289 is such that in. each cycle of the -machine, vafter a :portion of :wire

hasbeen fed into position between -the-insideand "outside formers of the machine and prior to the forward movementoftheslide 38, the lever fli.

The shape non through an angle of 90 of the other half of the cam 28B is such that in this next cycle of operations of the machine, after the feeding operation and before t-hesevering operation, the lever 2'12 is swung'in a direction opposite to the direction of its first swinging movement in the last preceding cycle, so that the beveled'end 282 of the wire will have been rotated through 180 about the longitudinal axis of the wire before the next piece is severed (Fig. 12). As the fed-in portion of Wire is then severed in response to the forward movement of the slide 38, the angular faces on its opposite ends will be located on the same side of the wire. Thereafter, the cam 280 will swing thelever 2E2 reversely to its initial starting position, thus causing the wire to be rotated through 90to removethe twistin the wire after the wire-severingoperation. From the above description it will be evident that the wire W is turned 180 first in one direction between successive wirecutting operations and then in the opposite direction before the next. wire-cutting operation to cause the angularfaces on the'opposite ends of each severed piece of wire to be located in the desired relation, 90 of each turning .movement occurring'after each severing operation so that the Wire is in untwisted condition each time it is fed. Accordingly, as the wire is fed it offers no resistance to the action of the feed rolls I58 and Manor is there any tendency for the wire -to rotate the quill 164 and bushing 265, such as would occur if the wire were fed in a twisted condition. The feeding and turning movements imparted to the wire during two successive cycles of operation of the machine are illustrateddiagrammatically. in Figs. 11' to 14 inclusive. As shown particularly in Figs. 12 and 14, the passage 284 for the wire W in the nozzle 14 is-angular in cross section and is sufficiently large to permit 'the wire to be turned therein, two surfaces of the passage acting by engagement with adjacent faces of the wire tosupport it during the wirecutting operation. i

In the illustrated machine each staple is formed with its cross-bar extending laterally of the slide through the same angle in the opposite direction in' the next cycle of, operations, said turning means beingso constructed as to turn the materialreversely to ';its starting position in each cycle after the severing operation.

Fig. 15 shows a section of a shoe of the through-and-tl nough sewed type illustrating the relation of the staplesS to the seam 15 whereby the outsole is secured to theinsole. It will be evident that the staples are driven, in the locations illustrated, each Witlithe ends of its legs-deflected substantially in the plane of the cross-bar of the staple so as to avoid any danger that they will interfere with the outsole stitches.
