20 Claims.

This invention relates to shoe machines and particularly to improvements in lasting machines of the type disclosed and claimed in United States Letters Patent No. 2,411,827, issued in my name on November 26, 1946. It is to be understood, however, that features of the present invention are not limited in their utility to use in this type of machine.

The machine of the above-mentioned patent is provided with a rapidly reciprocating gripper for seizing the lasting margin of the stock to be lasted, in different 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 to the shoe bottom and over a protective shield portion of a shoe bottom rest; a presser-feed member, operating in time relation to the gripper, for'pressing and pounding the overdrawn lasting margin of the stock into adhering relation with the shoe-buttom part and also movable, thereafter, in a direction to feed the shoe; and a feed-retaining member for preventing retrograde movement of the shoe and for retaining previously overlasted stock from being displaced by the next succeeding action of the gripper. It will be understood, in the specification and in the claims appended thereto, as in my prior patent mentioned above, that the term lasting is used in a somewhat broadened sense and is intended to include not only the conventional lasting operation-but also other analogous operations such, for example, as the working of the margin of a platform cover over a platform, while the term lasting margin is intended to include that portion of a platform cover, or other shoe part, which corresponds to a like portion of the upper stock of a conventional shoe.

As already stated, the stock is tensloned over the protective shield portion of a bottom rest, and to facilitate the introduction of work to the machine this bottom rest is, in accordance with a feature of the invention, movable by spring means to an inoperative position, operator-controlled means being provided for returning the bottom rest to operative position, against the action of the spring means, in which its shield portion will engage the bottom of a shoe held thereagainst, by the operator, close to its marginal edge. This operator-controlled means is also adapted to hold the front gripper jaw in its forward position and away from the reciprocating rear jaw, thus further facilitating the insertion of the lasting margin of the stock between the jaws.

As explained above, in this type of machine.

the stock to be lasted in tensioned heightwise of the shoe by the grippers which pull it inwardly from the edge of the shoe, in a direction substantially parallel to the bottom of the shoe, and over a shield portion'of a bottom rest which not only serves as means for changing the direction of the force applied to the stock, so that the pull parallel to the shoe bottom results in a tensioning of the stock in a direction heightwise of the shoe, but also protects the edge of the shoe bottom element, such, for example, as a soft platform, from distortion. Duringthe action of the grippers, the inside faceof the lasting margin of the stock is drawn quite tightly against a part of the bottom rest adjacent toits shield portion and considerable frictional resistance to movement of the stockthereover is produced. Especially is this so Where the inside face of the lasting margin is coated with an adhesive. This frictional resistance must, of course, be overcome by the gripper, in addition to the force for tensioning the stock, and the pull necessary to overcome this frictional resistance, and also adequately to tension the stock, in some instances becomes quite large and may approach the tearing strength of the material.

It is therefore an object of this invention to provide, in a lasting machine of this type, means for facilitating the lasting operation by eliminating the frictional resistanceof the part of the bottom rest, adjacent to the shield portion, on the lasting margin of thestock, as it is being pulled inwardly thereover I by the gripper and/or applying to the stock an additional pull in a direction to assist the gripper in tensioning the stock. To this end, the herein illustrated machine is provided with a bottom rest having a rotary-member for engaging thelasting margin of the stock as it is drawn inwardly byfthe gripper. This member comprises a" rotary spindle so mounted adjacent to the shield portion of. the bottom rest as to engage the lasting margin of the stock as it is being acted on by the gripper and to serve as an anti-friction means. Preferably, and as herein shown, this spindle is power driven at a high speed so that its surfacemoves at a rate somewhat in excess of the linear speed of movement of the stock. When so driven, the spindle, in addition to the anti frictio'n action, mentioned above, exerts on the lasting margin a frictional drag that augments thejpulling action of the gripper and the 'tensioning of the stock is correspondingly increasedn' Thi s spindle is tapered and is inclined downwardly and inwardly of the machine, and lengthwise-of the shoe, to, and

for! holding: the

preferably a little beyond, the edge of the shoe bottom. With the spindle thus positioned it has I operative position, in which it is held by a spring,

toits operating position, and associated withthe bottom rest is means for holdingthe front grip- V per jaw in an inoperative 'position.against the action of a relatively strOng'grippeFclosing spring. This arrangement necessitates the use of a strong treadle spring which results in" a-Lratheri hard treadle action that may be tiring tolthe operator. Therefore, and in accordance with 'a' further feature of this invention, the herein illus trated machine is pfiiv'idd with novel and improvedmeans'foractuatingtl'le bottom rest and for holding'the 'frontgripperjaw in'its inoperative position: Asshownrthc bottom rest is op- V tcgglei quite" rigidii" in s perati e position, where" it: Inuit he zco al pun r the gripper. 7 N he s These and other objects and features of the invention will become'apparent from the following detailed'dsscriptionoftheembodimentthereof shown intheaccompanying drawings and will be pointed out'inthe claims-L In the drawings, 7 7 p V Fig; its a View in sidepleva-tion of a machine of the typedisclosed'in the-*abbvwmehtioned application providedwit the featuresof this invention, a portion off-the headaand' other parts being broken away todacilitate the I disclosure;

r The rear gripper jawflli se attaohedby means of a clamping bolt 39, to'tlie forwardend of a carrier 32 which is supported by two rocker arms 34, 35 journaled respectively on fixed cross shafts 38and '40 that extend across the lower portion 24 9f the head 22, This carrier is pivotally s e- -cured ,togthesero "er arrns by means of studs 42,

ri er'jaws are closedgorrthelstockto be lasted by means of tnesprinegltfliandi drawithis stock and on the rod I02. ;this projection engages'the 'coIIarYZUD and the ing the stock in a direction heightwise of the shoe. The arm I52 to which the spring I50 is anchored has a hub I5I which is journaled on a shaft I54 that is rotatably mounted in the top portion 26 of the head of the machine, and extending upwardly from this hub is a second arm I56 provided with a spring-locking plunger I58 which fits into one of several holes I60 formed in the upper end of a third arm I62 which extends upwardly from a hub I6I that is secured to the shaft I54. As will appear below, the shaft I54 is held against rotation during the operation of the machine so that the tension of the spring I50, and accordingly the closingv pressure of the gripping jaws on the stock, may be varied by shifting the spring plunger I56 from one hole to another.

As the stock is thus pulled inwardly over, and in a direction substantially parallel to, the bottom of the shoe, it is drawn over the inner end of the bottom rest I4, and also over a portion H6 thereof which is positioned directly below and in alinement with thevline of action of the gripper so as to constitute a lasting shield orabutment. Thus the horizontally directed stress applied by the gripper is transposed into a vertical pull for tensioning the stock in a direction perpendicular to the shoe bottom and, at the same time, distortion of theshoe bottom member prevented. The bottom .rest and lasting shield I4 are mounted for movement outwardly away from the edge gage roll 26, for the purpose of facilitatin the beginning of a lasting operation, in the following manner. The bottom rest and lasting shield is removably secured by screws I64 to an elongated cylindrical member I66 which itself is secured, by bolts I68, to an arm I14 that is journaled on a shaft I18 supported in a forwardly projecting portion of the head part 26. Also Journaled on'this shaft is alhub member I86 from which project two arms I82 and I 84, the former being curved so as to extend rearwardly of the machine and at its end carrying a link I86 which is connected by a pin I81 to an arm I88 extending upwardly from a hub I98 that is secured to ashaft I92; seeiFig. 1. This shaft is Journaled in the head portion 26 and extends beyond one side thereof where it carries a lever I94 to which is secured a link I96, see Fig. 2. The hub of the lever I94 has spaced stop projections I9I and I93 which are adapted to engage a stop pin I95 that projects outwardly from the head portion'26. The arm I'I4 extends above the shaft I18 and is adjustably connected to the arm I82 by means'of a clamp screw I8I and slot'I83. When the linkis moved to the position shown in Fig. 1, by the depression of a treadle, not shown, the tog le formed by the link I86 and the arm'IB8 is straightened and'the bottom rest I4 movedto its operative position, the stop I9I engaging the pin I95. Upon release of the treadle'a spring, not shown, moves the link upwardly, thus breaking the above-mentioned toggle, and swinging the arm I14 in a clockwise direction, to move'the bottom rest outwardly to its inoperative position, the stop I93 now engaging the pin I95.

Secured to the arm I84 is a link I89 that extends rearwardly of the machine where it is connected to an arm I91, which extends downwardly from the hub I6I that carries the arm I62. This arm has at its lower end an offset projection I99 that is in line with a collar 20!) When'the treadle is released,

6, front gripper jaw is thus held in its extreme forward position. Also, since the arm I91 and arm I62 are secured to the shaft I54, the arm I52 will be swung in a clockwise direction to relieve the tension of the gripper-closing spring I50. With this arrangement, only a relatively light treadle spring is required and the treadle action is very easy. Also, when the treadle is depressed, the bottom rest is held in its operative position, where, as already noted, it must oppose the horizontal stress applied by the gripper, quite rigidly by the straightened toggle link E86 and arm I66, and without any extra effort on the part of the operator.

The stock which has been tensioned and drawn 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 gripper, by means of the presser-feed-member, or presser-feed-foot, I6, which thereafter,v and while in engagement with the stock, is moved laterally to feed the shoe. This presser-feedfoot I6 is adjustably secured by a screw 240 to the outer end of a lever 242 which is pivotally mounted by means of a stud 24I on an upwardly extending arm 244 formed integrally with a shaft 266 that is journaled in a portionof the head of the machine. The lever 242 is oscillated, in time relation to the operation of theigrippers, to move the presser-feed-foot I6 against the stock, by means of an eccentric, not shown, carried by the shaft 52, and the shaft 246 is oscillated, to move the presser-feed-foot back and forth in a direction extending lengthwise of the shoe, by means of an angle crank, not shown, also mounted on the shaft 52. The action of the presser-feed-foot I6 to press the overdrawn lasting margin against the shoe bottom and, thereafter, to feed the shoe, is the same asset forth in the above-mentioned patent and need not be further explained here.

The shoe is held against retrograde movement during the return, or back-feeding, movement of the presser-feed-foot I6, and lifting of the stock by the next succeeding pulling action of the gripper is prevented, by the feed-retaining member IS. The member I8 is constructed and arranged as in the machine of the above-men'- tioned patent and is operated in the same manner from an eccentric, not shown, on the main drive shaft 52.

In the machine of the mentioned patent, the bottom rest has a surface, inclined downwardly and inwardly of the machine, which is located adjacent to the shield portion thereof. As the stock is pulled over the bottom of the shoe, inwardly from the edge of the shoe bottom, the lasting margin is drawn quite tightly against this top surface and also against the shield portion with the result that there is considerable friction between the stock and the bottom rest tending to resist the movement of the stock inwardly of the shoe bottom, particularly when that surface of the stock engaging the bottom rest is coated with a tacky adhesive. In order to eliminate the resulting frictional resistance, which makes it more difficult properly to tension the stock, the herein illustrated machine is provided with a rotary spindle 326 having a tapered lower end 322, which occupies substantially'the same position as the mentioned surface, and over which the lasting margin of the stock rides as it is being tensioned by the gripper. As shown in Figs. 1, 3

and 4,-th1 spindle is inc ined .d wnwa dlra si 7 7' inwardly of the machine, and lengthwise: of; the shoe, so that'its tapered lower end extends down tothe underside of the bottom'rest'andiclose to the shield portion llilatthe edge of the shoe.

The spindle 32B is journaled in a bearing-bore 324, formed in the elongatedcylindrical member I66, on the upper endof which is mounted 'aigear housing 326 that contains two meshing spiral gears, 328 and 338. The gear'323 is securedto the upper. end of .the spindle flowhileithegear 330 is secured to a shaft 332, .Journaled. in: an extension 323 oi'the housing 326, that 'isicone neotedby-a universal joint 334 to an elongated shaft 335. The shaft336iisih turn connected, layer-universal joint 338, to a shaft 340 journaled in a gear housing 342 mounted on the head-of the. machinezby screws 334, which carries a spiral gear'346 that meshes with gear teeth-348 formed directly on the main drive shaft 52. Atubul'ar housing 359 covers the'shaft 336 and is mounted at: one end in the gear housing 342'. The other en'd'of this housing is shapedt'o fit in a spherical recess 3 33 in the extension 323 of the gear housing 326. The centers of the universal joint. 3'34 and of the recess 343are in line with the axis of the shaft I18, see Fig. 1, so that the housing and joint may articulate about this center, when the bottom restis moved from one position to the other, without subjecting the shaftor its housing to any undue strain. I

Theoperatio'n of the herein disclosed machine is, ingeneral, the same as-that of the machlne shownin the above-mentioned patent andishould be readily understood. It is briefly as follows: Referring to the drawings, when the .treadle, not shown, is released, the link [96 will be elevated by thetrea'dle spring, also not shown, thus breakingthe'toggle link I85 and arm I68. Thebo'ttorn rest- M willnow be swung to the left from the position shown in Fig; -1, and the front gripper jawheld in its forward position, away from th'e rear gripper jaw, by the offset projection 1-99 (in arm. Eel, thusfacilitating the entry of a workpiece. such, for example, asa slip-lasted shoe having a platform P, platform cover 0. and an upper. U on a last L. After the shoe has'been placed in the machine with the edge of ltsplatform against the edge gage 20, and with the bot tom face of its platform'held up against thebo'ttornrest' lithe treadle is-released to-permit" the bottom rest to swingiintothe position "shown -i'n Mg. 3 and the front gripper to move toward-the rear, gripperrjaw'. As the lasting operation proceeds,the-gripper. jaws closeion the lastingzmarginof the cover C and pull-it inwardly from'the rises; At this time the. feed-retaining finger l8 descends to apply additional pressure onthe overflast'ed stock and also to prevent retrograde movement of the shoe during the back-feeding move; ment of the press'er-feed-foot whichno'w occurs. These operations are repeated rapidly as the lasting operation proceeds along the peripheral edge of 'thesl'ioej V j v I will be' apparent from an inspectionofl igs. 2 and'- 3', the-'las'tingmargin of the stock-isdrawn agalnstthe" tapered end 322 of. the spindle 3211 8; asitiis pulledginwardly over the shoe bottom by the. grippers; Preferably,v and as, herein illustrated, this spindleisrrotated from the ,maindrive shaft and .the'gearing ratio:is;such thatthe speed of the surface .of; the tapered endis somewhat in excess of: the rate-of:movement,0f the stock: by the gripper.
