This invention relates to shoe machines and particularly to machines for lasting the uppers which affords protection against displacement of shoes or periorming analogous operations on bcttom part during the lasting operation. i ~ other shoe parts. ,- . ~ of the'lasted stock or distortion of the shoe With these and otherobjects in view,the herein f In lasting, as this term is understood in the illustrated machine is, in accordance with fea rade, the upper stock is tensioned heightwise of tures of the invention, provided with a rapidly reciprocating,r gripper for seizing the lasting the last, its lasting margin is drawn over, or otherwise worked into. overlasted position, onto margin of the' stock to ,bel lasted, in diiierent o’ locations successively along the edge of the shoe bottom, and for tensioning it heightwise of the shoe by pulling it’inwardly from the edge of the shoe bottom in a direction substantially parallel the bottom of the shoe, and the overlasted margin is secured in lasted position, as by cement or metallic fastenings, to a shoe-bottom member such, for example, as van insole. Recently there has been introduced to the trade'a type of shoe sometimes called a slip-in lasted shoe, the manu >to the `shoe bottom and over a protective shield 'portion of a shoe bottom rest; a presser-feed facture of which, whileit does notinvolve the conventional lasting operation, outlined above, member, operating in time relationl to the gripper, for pressing and pounding the overdrawn last does employ a procedure closely analogous there ing margin of the stock into adhering relation with the shoe-bottom part and also movable, thereafter, in a direction to feed the shoe; and a to, namely, the operation of tensioninga plat, form cover heightwise of the-shoe, working the margin of the cover stock- over onto a >platform feed-,retaining _member for preventing retrograde movement of the shoe `and forretaining previ. ously overlasted' stock from _being displaced by thenext succeeding action of the gripper. It is an object of this invention to provide av _For preventing the adhesively coated lasting novel and improved machine for performing 25. merg-_ín of the stock from sticking ,to the gripper either the conventional lasting operation or such jaw which engagesit, >the machine,~~in accordance which serves as a> shoe bottom member, and se curing, as bycement, this overdrawn margin to the platform. an analogous operation as the one justmen ` tioned.. Accordingly, in this specification, as well asin theY claims, the term “lasting” is used in a ~ with a _further feature of the invention, is pro vided with gripper-operating» means arranged to eiîectseparation of thegripper jaws by indi somewhat broadened sense and is intended to 30 vidual movements thereof in opposite directionsinclude not only the conventional lasting opera away from kthe said margin. In, the illustrated tion but also other analogous operations, while machine the >gripper mechanism comprises a" the terms “lasting Vmargin” and ‘_‘overlasted power-reciprocated rear gripper jaw, a front Ajaw marginî’ are intended to include that portion of associated therewith for movement relative there a platform cover, or other part, which corresponds 35 to, resilient lmeans >for' closing the jaws, and to the likeportion ofthe upper stock of a con means controlling the position of >the front jaw ventional shoe. so that the jaws close on the stock, move together '~ More particularly, it is an object of this inven-` forwardly lover the shoe bottom, 'and ñnally sepa rate to release the stock, the controlling means being arranged to continue the forward movement tion to` provide `an vimproved lasting> machine thatis very' speedy in operation, .efficient in its action, and especially adapted vfor performing` of the front jaw, as the vrear jaw moves rear lasting operations in which the securing of the? overlasted margin of the Vstock to the bottom of Í f wardly, thus to eiïect separation of the` jaws in the manner setforth. the shoe is effected by means of an> adhesive, and I where lthe lasting operation proceeds step bystep` Without interruption -along the .peripheral `edge of the shoe bottom. It is, hOWever, to be under stood that in certain aspects the invention is of broaderV scope «and that features vthereof have 4utility in other types of lasting. , Lt is ¿also an object of this invention to provide an improved lasting machine in the operation> of which the lastiner operation progresses >auto' ‘~ f " v " ” As stated above„the.stock is _tensioned over the ,si en protectiveshield portion of a bottom rest, and vto 4facilitate theintroduction of work to the ,ma chine ,this bottomk rest is, in accordance with a feature of the invention, movable by spring meansy . 50o, to >`an inoperative position, operator-controlledy means being provided *for >returningthe bottom restfgto operative ~position, against the action of thejspring means, in which its shield portion will engagethe bottom of ,a shoe held’thereagainst, by ¿ the operator, closel to its marginal edge.Y This maticall-y along the peripheral ,edge of the shoe bottoni by small, but unite, increments, and 65 spring means is _also >adapted to hold the front 2,411,827 3 gripper jaw in its forward position and away from the reciprocating rear jaw, thus further facili tating the insertion of the lasting margin of the stock between the jaws. The presser-feed member` of the illustrated nia chine, as above mentioned, acts as a presser, or hammer, to press, or pound, the overlasted mar gin of the stock into adhering relation to the bot toni of the shoe, and also as a feed-foot to move the shoe bodily in a feeding direction. To facil itate this feeding action this presser-feed-foot is, in accordance with another feature of the inven tion, constructed and arranged to move the shoe downwardly and away from the bottom rest, thus avoiding any tendency for the adhesively coated shoe bottom to stick to the bottom rest or to drag thereon. This presser-feed-foot descends sub stantially vertically onto the overlasted margin close to the point of action of the grip-per, and its 4 during the return, or back-feeding, movement of the presser-feed-foot; and an edge gage roll 2Q for positioning the shoe laterally. These instru mentalities are all mounted on, and operated by mechanism contained within, a hollow head con struction 22 comprising a lower portion 24 and a removable top part 25 secured thereto by means of cap screws 28, 28. The rear gripper jaw l!) is attached, by means of a clamping bolt 39, to the forward end of a carrier 32 which is supported by two rocker arms 34, 36 journaled respectively on fixed cross shafts 38 and 4€] that extend across the lower portion 24 of the head 22. This carrier is pivotally se 15 cured to these rocker arms by means of studs 42, 44 and is movable forwardly and rearwardly of the machine by means of a third rocker arm 46 that extends upwardly from a hub member 48 common to it and to the >rocker arm S6. The the stock between the successive points of action of the presser-feed-foot is nicely folded into small and unobjectionable plaits, a feature of especial rocker arms 34 and 36, together with that part of the carrier 32 which extends between said arms, constitute a parallel motion linkage so that the carrier always remains horizontal during its for importance where the lasting operation proceeds ward and rearward movements. feeding increment is so small that any fullness of around sharply curved portions of a shoe, as at the toe and heel ends, and adjacent to the ball. ' For oscillating the rocker arm 46, to impart the aforementioned movements to the carrier 32, there is provided an eccentric 50 formed inte grally with a main drive shaft 52V that extends across the lower portion 24 of the head and The effectiveness of the presser-feet-foot to effect adherence of the stock, and to feed the shoe, and that of the feed-retainer to prevent retro grade movement of the shoe, is enhanced by con 30 which is journaled in anti-friction bearings 54, 56 mounted in said lower head portion. An end iining their zones of operations to narrow areas of this shaft projects beyond one side of the and by providing them with sharpened teeth. These and other features of the invention will head, see Fig. 2, and on ythis end there is secured a drive pulley 58 which is connected by means become apparent in the following detailed de scription of the embodiment thereof shown in 35 of a belt, not shown, to any suitable source of power such as, for example, an electric motor. the accompanying drawings and will be pointed Surrounding the eccentric 5G there is an eccen tric strap 69 from which extends an arm 62. This arm is connected by means of a ball joint, Fig. 1 is a view in side elevation of a machine embodying the features of the present invention, 40 including a ball $4, to a link 56 and by a ball jointl including a ball G8, to a link 1G, a spring certain portions being broken away to show the out in the claims.

The link 1B is connected by a ball joint, comprising a ball l'l and a spring clip 13, to the upper end of one arm 'i4 of a bell crank having a second arm 16, located on the outside of the head portion 24 and provided with an operat ing handle 80 in which is positioned a spring locking plunger 82. This locking plunger is adapted to be positioned selectively in one of sev eral recesses 84, formed in an arcuately shaped raised portion Bâ on the head, see Fig. 2, thus to respectively, of the operating instrumentalities shown in Fig. 4 but with these instrumentalities in diiïerent operating positions; vary the length 0f the toggle formed by the link lil and the arm 14 for a purpose to be explained below. The link‘ 66 is connected to the rocker Fig. 7 is a View in side elevation of the front part of the machine with the operating instrumental ities in position to receive a 'shoe and with certain parts omitted; and 88 and a spring clip 90. As the main shaft 52 and eccentric 5D are rotated ¿the link 10 will be Fig. 8 is a Timing Chart. Referring to the drawings, the operating in strumentalities of the illustrated machine com prise a gripper, including a rear gripper jaw I0 and a front gripper jaw l2, for seizing the last arm 4E by means of a ball joint including a ball oscillated about the ball joint 'H and this oscil lating movement of the link 19 will be trans mitted to the arm 4B by the link 66, thus caus ing the carrier 32, together with the inner grip per jaw lo which is attached thereto, to be recip rocated forwardly and rearwardly of the ma chine. By varying the length of the toggle formed by the link 10 and the arm 14, in the manner pointed out above, the extent of the for ing margin of the stock and applying lasting stress thereto; a, shoe bottom rest and lasting shield i4 for engaging and positioning heightwise,the bot ward movement of the carrier and of the rear tom of'a shoe and over which thev lasting margin v is drawn by the stress applied thereto by theY 70 gripper jaw lil may be varied. v The front gripper jaw l2 is secured, by means gripper; a presser-feed member I6 for pressing of a clamp nut |03 and washer >Iiil, on the outer the tensioned lasting margin down onto the bot end of an elongated rod |02 which is slidably tom of the shoe and fo-r exerting a feeding force mounted in bearing bores |04, |06 formed in on theshoe; a feed-retaining member I8 for holding the shoe against retrograde movement 75 bosses |08, H0 -on the carrier 32.

The presser-feed-foot I6 is preferably so which is connected by means of a link 2I4 to an arm 2I6 which extends downwardly from a hub arranged that in moving downwardly against the shoe it tends, momentarily, to push the shoe slightly away from the bottom rest I4, or at least -appreciably to reduce the pressure of the shoe bottom against the bottom rest, Vthus reducing any tendency of the bottom rest to stick to the bottom of the shoe, -see Figs. 3, 4, 5 and 6. The angle crank 254 operates in a block 253that is embraced by an elongated yoke member 2,82, see Fig, la, which is secured to the shaft 246 by 2I8 which, like hub |94, is freely rotatable upon the shaft |54. This arm has at its lower end an oifset boss 220 which, when the treadle is re leased, bears against a collar 222 on the rod |32 thus to hold the front gripper jaw I2 in its for ward position. Accordingly, until the treadle is depressed and the bottom rest and lasting shield I4 moved into operative position, the rear gripper jaw I 0 merely reciprocates idly without engaging the front gripper `j-aw or exerting any pulling means of a set screw 284, see Fig, 2. The hub member 265 is held on the shaft 268 by means of an upstanding piece of flat stock 286 which is mounted on a reduced end of the shaft 48 and held against a >boss 288 on the web portion |22 by action on the stock. As will be seen from Fig. 7, when the outer jaw is thus held in its outermost position by the boss 220 the rods |02 and |03 are separated a small amount. ` The stock which has been tensioned and drawn .s means of a nut 290. inwardly over the shoe bottom by the gripper in the manner above explained is pressed firmly against the bottom of the shoe, and into lasted position thereon, just as it is released by the grip Theshoe is held against retrograde movement during the return, or back-feeding, movement of I6 is adjustably secured by a screw 240 to the outer end of a lever 242 which is pivotally mount a shaft 298 mounted in the head portion 24. Also extending from the hub 236 are two other arms 380 and 302, the former of which extends up wardly to receive a tension spring 304, stretched betweenit and an anchor pin 306 carried by the upper Vhead portion 26, see Fig. 1,_while the lat 40 ter arm extends downwardly and rearwardly and the presser-feed-foot I6, and lifting of the stock by the next succeeding pulling action of the grip per, by means of the presser-feed-member, or 30 per is prevented, by the feed-retaining member i8.' The member I8 is secured by means of a presser-feed-foot, I6, which thereafter, and bolt 202 to the outer end of an arm 284 which is while in engagement with the stock, is moved formed integrally with a hub 296, journaled `on laterally to feed the shoe. This presser-feed-foot ed by means of a stud 24| on an upwardly ex tending arm 244 formed integrally with a shaft 246 that is journaled in an elongated bushing 248 mounted in a bore 25E! in the web portion |22. The lever 242 is oscillated, in time relation to the operation of the grippers, to move the presser-f feed-foot I6 against the stock, by means of an isY formed with a cam track 308, having an arcu ate part 301 and an eccentric part 309, over which travels a cam roller 3I0. The cam roller 3|0 isrjournaled on a stud SI2 mounted in an arm eccentric 252, carried by the shaft 52,v and the shaft 246 is oscillated, to move the presser-feed foot back and forth in a direction extending 45 3|4 which extends radially from the hub mem ber 266. IThe cam track 368 is so shaped that as lengthwise of the shoe, by means of an angle the hub 266 is oscillated, by the eccentric 252, crank 254 also carried by the shaft 52, see Fig. link 285 and arm 264, the feed-retaining mem la..` To augment its pressing action and to in ber I8 will be successively urged toward the shoe sure against slippage on the stock, the presser feed-foot I6 is formed as a narrow blade-like bottom, by the spring 334, held in this position element and is provided with a series of sharpened for a` half turn of the main shaft and while roller teeth 255, see Figs. l, 4, 6 and '1. 3|0` rides on the arcuate part 381, and raised therefrom by the roll 3I0 acting against the ec ' Surrounding the eccentric 252 is a strap 256 from which extends an‘arm 258 which is con nected, by means of a ball joint comprising a ball . 260 and a spring clip 262, to an arm 264 that extends downwardly from a hub member 266 journaled on a shaft 268 mounted in a side wall centric part 309 of cam surface 308. These move ments of the feed-retaining member are so timed that it comes down against the overlasted stock just as the presser-feed-foot I6 completes a feed ing movement, remains down on the stock, to prevent retrograde movement of the shoe and of the housing portion 26, see Fig. 2. .Also ex tending from the hub 266 is an arm 210 and con 60 lifting of the overlasted stock by the gripper, while the presser-feed-foot is back feeding and during nected to the outer end of `this arm by a ball joint the` next closing and pulling action of the gripper, comprising a ball 212 and a spring clip 214 is a and then is lifted away from the shoe bottom just link 216 the opposite end of which is connected, as the -presser-feed-foot I6 begins its next suc by a ball joint comprising a ball 218 and a spring 65 ceeding feeding movement. To augment its hold clip 280, to one end of the lever 242. ing and pressing action the feed-retaining mem In the position of the parts as shown in Fig. 1, ber is formed as a narrow blade-like element and the presser-feed-foot I6 is in its lowermost po is provided with a series of sharpened teeth 3I5 sition and has just completed a feed stro-ke.
