Application filed December 21, 1908. Serial No. 38,541.

To all whom it may concern:

Be it known that I, ARTHUR L. Russian,

a citizen of the United States, residing at Hyde Park, in the county of Norfolk and.

State of Massachusetts, have invented certain Improvements in Machines for Use in the Manufacture of Boots and Shoes, 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.

This invention relates to lastin machines of the class employing grippers or pulling the upper and layin it over a last and, for some classes of wori, employingwipers to press the upper into position to be secured by a. binder of wire.

The invention is illustrated as applied to a machine of the type shown in United States Letters Patent No. 584,744, and has for one object to improve the mechanism for V actuating the grippers. At the toe and someto take care of are required to plait or fold the times at other parts of the shoe the grippers marginal upper upon the shoe bottom the fullness which isincident to bending the upper inwardly over the convex edge of the last bottom.

An important feature of this invention consists in actuating the grippers for the purpose of plaiting the upper about an axis that extends in the general direction of the portion of the strain upon the upper to form the plait or fold, an also about another axis at an angle to the first one to lay the fold. As herein shown the grippers are turned or rotated while overdrawing the upper about an axis that extends arallel with or at an oblique angle to the face of the shoe bottom. This forms in the stock the plait or fold. Preferably while this fold is being formed'the grippers receive a. turning or swinging movement about a different axis which may extend substantially perpendicular to the.

shoe bottom and lays or locates the fold upon the shoe bottom in suitable angular relation to the edge of the last. The first mentioned movement may take place about an axis that lies in or parallel with the gripping faces of the jaws of the grippers and extends in the neral direction of the strain under which t e upper is being held. The second Inovement may advantageously take place about and the stock in advance portions. of the .over and conformed to the edge of the last an axis that extends in the general direction of the usual updrawing movement of, the grippers which is approximately perpendicular to the last bottom and that axis should for the best results be so located with relation to the edge of the last and the end of the gripper jaws that the fold or plait formed will. not extend as a pucker or wrinkle to or beyond the edge of the shoe bottom and show after the welt or the sole is applied to the shoe.

In accordance with a preferred arrange ment the grippers comprise tapered jaws which are narrow at the outer ends so that when they are rotated about the oblique axis as proposed they will form a plait that tapers toward the edge of the shoe bottom and is widest at its inner end. This provision of tapering gripper jaws with means for rotatin them to form a tapered pla'it is a valuable eature of this invention. Preferably also the mechanism for swinging the grippers about the perpendicular axis and the mechanism for rotating the grippers about the oblique axis will be relatively arranged and timed to insure that the jaws in their rotation do not exert strains tending to pull out the plait previously formed. To this end said mechanism may be arranged to permit the rear edge of the gripper jaws, that is 'the edge next to the portion of upper last plaited and secured, to remain in substantially the same vertical rotation of the jaws. By reason of this arrangement theplait or fold is or may be formed mainly by drawing inwardly and backwardly the stock pulled by the grippers advance of the gripping point without danger of disarranging or undoing the plaits previously formed. This arrangement has also the ositive advanta that by pulling inwardly and backward y the upper in advance of the grippers said upper are pulled and the scope or range of action of the grip pers is widened so that fewer pulls are re quired to last a given portion of a shoe. A similar advantageous result may be obtained by rotating the grippers about an axis located at the rear edges of their gripping faces. The rotation and the swin 'ng of the grippers will preferably be yie dingly effected. By this means each of said moveplane during the mcnts will be caused to proceed only so far as is n'e'edful for taking up the fullness of the stock and snugly making and laying the fold or plait without straining or tearing the upper.

The formation of the gripping faces of the jaws for increasing their holding power is a novel feature of this invention. These jaws are so formed that the stock cannot move between them in the direction to pull out without automatically tightening the bite of the jaws upon the stock. To this end the jaws are formed to pull or gather in the stock widthwise between the gripping faces if the stock begins to slip toward the point of the jaws. -This is effected by providing one or both of the jaws with converging faces or walls between which the stock is gathered widthwise if it slips downward between the jaws. As shown one jaw has converging grooves formed by converging side walls and tapering in depth toward the point of the jaw so that stock is crowded together if it moves toward the pointof the jaw.- The other jaw is shown as having similarly formed ribs which crowd into the upper portions of the grooves a greater quantity of stock than the lower portions of the grooves will hold. The grooves and the ribsxmay have interlocking teeth to assist in holding the upper and the converging edges of the gripping faces of the jaws ma form gripping ribs between which the stoc is laterally gathered in or fulled up if it begins to slip. With the described construction the grip on the stock is automatically tightened as the stock slips so that the slipping cannot progress far enough to do any harm before it is automatically checked. This permits the grippers to be held closed by the application of less force than has heretofore been required.

The invention is shown for the purpose of explanation as applied to the machine illustrated in said Letters Patent No. 584,744 wherein are employed grippers having shanks extending substantially perpendicular to the plane of the shoe bottom when the shoe is in position to be lasted and mechanism operatively connected with the shanks for turning or swinging the grippers jaws about the longitudinal axis of said shanks and also moving the grippers laterally. I have in this illustrated embodiment of the invention retained the said mechanism and its connections for swinging the grippers about the perpendicular axis and have replaced the I. connect-ions for giving lateral movements to the grippers with connections extending tothe jaws for rotating them in or with relation to their shanks or carriers. The jaws are sjupported in their shanks for rotation about an axis which lies in a plane between their gripping faces which are disposedt obliquely to the shoe bottom. The

connection between said actuating mechanism and the jaws for rotating them may comprise means which can be adjusted during the operation of the machine for varying the extent of the rotatory movement imparted to the jaws according as the fullness to be pl'aited varies at different portions of the toe or other part of the shoe being lasted. In a modified construction the gripper jaws are formed with theirrear edges in substantially the oblique axis about which they are rotated. When jaws of this form are employed the turning movement about the ver- I tical axis may be omitted for the jaws obviously have no tendency to displace or pull out, during the formation of the plait, the upper just previously lasted and they do lay the plait being formed.

Lasting machines of the type herein shown that are adapted for making welt and turn shoes usually employa wiper or presser which, following the grippers as they pull and plait the upper over the last bottom, presses or. wipes the upper inwardly and snugly down upon the innersole. and holds it. while it is secured by a continuous binder or an individual fastening. A good form of wiper comprises a swinging plate the rear end of which rests continuously upon the shoe'bottom behind the grippers or on a portion of upper. already overworked while its acting edge extends across the path of the grippers to a point in advance of them. The advance. end of the wiper is reciprocated, being drawn back to permit the 1 0 grippers to pull the upper between it and the last, and then swinging inwardly to wipe the upper with a shearing action over the edge of the last. The heel end of the wiper is preferably pivoted back from its acting 105 edge so that the entire actingedge receives a movement backwardly and inwardly over the shoe bottom and assists materially not only in working the upper inwardly over the last but also in disposing of the fullness at the toe 110 or other convexedge of the last. It is cus tomary to employthe wiper only when plait ing the upper and to retract it to an inoperative positionand disconnect'it from its actuating means when the plaiting movements of the grippers are discontinued and they receive only their updrawing and overdrawingmovementsfor overworking the upper on portions of the shoe which do not require plaiting.

In machines as heretofore generally used the mechanism for imparting the plaiting movementsto th'egrippers and the means for projecting the wiper or presser have been operatively connected so that both were rendered operative together, and consequently neither the wiper nor the plaiting movements of the grippers could be employed separately.

It would sometimes however be advantageouS. to use the plaiting movements alone.

as, for example, at the sharp corner found in some shoes at. the junction of the ball and the shank at the inner side of the shoe and itwould sometimes be desirable to use the pressers or wiper, particularly the swinging wiper above described, without giving to the grippers their turning or plaiting movements as, for example, atthe slightly convex sides of the last adjacent to the more convex toe curve. An important feature of this invention consists in novel means for controlling the operation of the wiper and the grippers whereby either the wiper or the plaiting movements of the grippers may be employed separately or both together. The usua knee lever of the machine has connection with one of said parts and a second operating device is arranged, preferably within the knee yoke of said lever, to be actuated either independently of said lever or simultaneously therewith at the will of the operator. The second operating device may conveniently be a )ush bar acting against a return spring and arranged to havea slightlateral movement to permit engagement of a projection thereon with a locking shoulder to retain it in adjusted positio 'v As herein shown the push bar is connected with the wiper controlling mechanism and the knee lever is connected with the plaiting mechanism; .This'controlling. mechanism includes a cam slide which is a plate having inclined or wedge shaped acting faces that engage rolls on the rear ends of the wiper slides. Movement of the cam slide in one direction forces the wiper slides forwardly against the tension of their return springs While reverse movement dislodges the rolls from seats in the slide and permits the wiper slides to retract. The springs require to be fairly" stifi so that considerable force is needed for moving the controllingslide, and this has heretofore put an appreciable load upon the shifting device. In accordance with a further feature of this invention means is provided which is adapted to be set by the shifting device,.4herein shown as the push bar, in the path of a power driven )art by which the actuation of the cam slit e is ett'ectedto render the wipers operative or inoperative. This power driven part may take the form of an intermittently reciprocated wedge having two inclined sides into the path of one or the'other side of which a member shifted by'the push bar may be posi-- having been exhausted, therethrough to movethe controlling slide. in a second construction embodying this feature of the invention according to which a device is set and the machine effects the movement of the controlling slide a stud on the slide may be set by the shifting device at the same time that a stud on the other side of the wedge is with drawn. At the next advance of.the wedge it will act through the projected stud to movethe controlling slide in the desired direction. By simultaneously moving the two studs in opposite directions the depressed one may be arranged to stand adjacent to, but below, the point of the wedge after the slide has been moved so that when it is next raised it will be in a position to be actuated by its side of the wedge. This arrangement relieves the operator of the laborious part of the operation heretofore required for shifting the wiper controlling slide. The wedge for shifting this slide may be carried by one of the moving parts already machine.

In accordance with another feature of this invention novel means is provided for actuatingthe wiper while it is in operative posipresent in the tion and for connecting and disconnecting it and its actuator in time relation with its movement toward and from operative position. To this end a plunger connected with the movable wiper carrying ba'r supports a latch which is arranged for interlocking engagement with a moving part which may conveniently be the same part by which the controlling slide is actuated. The latch is carried by a rotatable sleeve for movement laterally into and out of interlocking engagement with its actuator. and the wiper controlling slide has an arm to engage the sleeve when the slide is moved in one direction and turn the latch away from the actuator while a spring moves the latch into engagement with the actuator when the slide is reversely moved. Any other suitable mechanism may be adopted to embody this feature of this invention.

It is customary to employ a binding wire instead of tacks to secure the upper in lasted position about the toe portion of the upper when the wiper is used and in accordance with another feature of this invention means is provided by which the tack delivering means is rendered inoperative when the wiper is rendered operative and vice versa. The means herein shown includes a connectionformed by a rod and the non-reciprocating or stationary wiper carrying bar between the wiper controlling slide and the yieldingly actuated tack separator whereby when the wiper is advanced into operative position the separator is locked. 'hen the wiper carrying bars are retracted the separator is unlocked. The illustrated arrangement for controllinrr the dpiivm-v as t-n-iru i1."-

- of contact of the driven block, extending the tack block and wiper and of sufficient the upper material into t-hegood characteristic that a tack is driven during the first complete cycle of the machines operation after the wiper is retracted and the separator unlocked. The described I combinations have the advantage that the settling of a single part which requires little force to shift renders operative power driven means which effects the several shiftings incident to the employment of the wipers and the binding of the lasted upper by wire, and the rewttingpf thesame part effects the reverse shiftings for discontinuing the use of the wipers and resuming the use of tacks to fasten the upper. The illustrated construction has the further advantage that a single actuator, which may be the lever already present in the machine for moving the tack carrier, is used for operating several parts so that the construction of the machine is simplified rather than complicated. The use of separate knee operated devices both arranged in the position in which machine operators are accustomed to use a knee lever is convenient and leaves the'two hands of the operator free for use in presenting the a shoe to the machine.- p

A further. feature of this invention consists in novel means for forcing or creasing the angle between the feather and the lip or shoulder of the innersole. As herein shown a member is mounted on the tack carrier in position, to be driven downwardly and outwardly by the tack driver bar to punch into the angle the stock which usually bridges over the angle from the wiper to the top of the shoulder. The operators have heretofore been expected to hold the shoe laterally and vertically against the advancing wiper with sufiicient force to cause the wiper to push the stock horizontally into the angle. In practice this requires the exertion of more strength on the part of the operator than he is willing to expend continuously throughout adays work, particularly about the toe portion of the shoe where the upper materials are thick and difficult to bend into the angle. As a result the upper is not-,-in many shoes, forced as well into the angle by the laster as it should beand an additional burden is put upon the welter to draw the upper into the angle by the sewing thread. It has been proposed to provide a lasting machine with a vertically movable tack block which was driven downwardly upon the shoe bottom by the driver bar. The area from the edge of the shoe inwardly to the end of the block, distributedthe blow over a large surface. The present invention contemplates, as distinguished from that, a blade or creasing tool that shall have a narrow area of contact located over and immediately adjacent to the angle at the front of thickness to prevent cutting or otherwise inuring the shoe stock. This blade will preferably be guided to move somewhat outwardly toward the shoulder as well as downwardly and by reason of its direction of movement and its small striking face will not objectionably jar 'the'shoe or the workmans hands while holding the shoe. These-and other features of the invention, mcludingthe novel details of construction shown and certain combinations of parts disclosed, will befully explained in'connection with the following description of an a paratus embodying the invention and W111 then be pointed out in theclaims.

The gripper carrying bar 13 is outwar y deflected at its lower end and has a bearing extending obliquely downwardly and inwardly within which the grippers are rotatably mounted. The lppers comprise a shank or cylindrical b 0c 20 held in the hearing by aflange at one endand an arm per carrying bar-13 which has" a. y-which it is suspended from .the

The block has a split clamp while the otherjaw 25 is guided throu h the block to which it is connected by lin s 26 while the end of its shank is located in the longitudinal axis of the block and has aball and socket engagement with a leverf 28. This lever is forked and is fulcrumed' slots in its sides for guiding the cross head 30 of the closing rod '12. The ends of the. cross head extend into cam slots 32 in the forks of the closing. lever for actuating the lever to close jaw 25 upon jaw 24 or u on? the stock between the jaws when the ro l2- is forceddownwardly. The gripping faces of the jaws are preferably tapering from a: broad head to a blunt point to facilitate the formation of plaits or'folds in the upper-asl will be described and these. faces may have the surface formation shown in Fig. 11 to'eni able them to hold the stock securely. This} formation comprises in one jaw grooves 35 -the side walls of which extend oblique to the direction of the pull to be exerted on the stock; and converge toward the point of the jaw. The grooves may increase in depth from the point toward the head and preferably will? be arranged at an angle to one another.-

opposite directions toward the point of the jaw and the raised faces between the grooves and at eitherside of the .jaw are of substan-; tially the same width throughout "theirlength. The upper clamped against jaw 25' is compressed into the grooves and cannotslip toward the pointof the jaw without} being compressed laterally between the con-f verging side walls of the grooves and, as the oint the compression in *t e direction 0 the thickness of the stock is also increased if the stock slips outwardl in the grippers. Thej jaw 24 has ribs 36 which force the stock into the grooves. 7 These ribs resemble in shape the grooves 35 in that the decrease in width and in height toward t e point of the jaw, although preferably to a less extent so that they wedge or pinch the upper against the walls of the grooves if it begins to slip The raised faces between'the sev-' eral ribs 36 on the one jaw and between the grooves 35 in the other impress themselves into the upper as the jaws close and compelling it to gather in or full u between the lower portions of the jaws w ereby the pressure upon the stockis'increased and the slipping automatically checked; Teeth are formed on the raised faces between thegrooves 35 and on the ribs 36 to The bearing in the carrier for the gripper block 20 extends oblique to the plane of the tion in which the upper extends from the .edge of the last to the grippers'in the over- ,drawing movement of the grippers. The arm 22 serves to rotate the grippers about this axis when plaitiiig of the upper is desired and to th1s end the arm is connected by the rod 40, elbow lever 42 and extensible rod 44 with a segment block 45 adapted to be adjusted off .the center at either side of the rocker 46which is fast on a sleeve 48 and is goscillated by a lever 50 receiving motion from a groove in the front face of the cam block 5. "The segment block is set by a connection explained in United States Letters Patent No.

500,141 with a vertical manually shiftable ,rockshaft hereinafter referred to. The

shown in i 1, through which the rotating movement the grippers for the formation of plaits is yieldingly effected. The movejment for forming plaits is illustrated in Figs. 4,5, 6 and .7. In Fi 1 there is shown means for also turning t e grippers about an aXis which ,is substantially perpendicular [to the lane of the shoe bottom. This may be emp oyed to swing the grippers laterally in laying the plait and cause them, while tforming the plait, to take up stock mainly or wholly from that side which is in advance of thegrippers. This has the advantage of extending the scope or range of action of the grippers, causing them to gather in the up- I per farther-along the' edge of the shoe, as shown ln'Fl 7, sothat the pulling olnts may be fart er apart and fewer p ls re.-

itage is that-the previously formed plait is ,not pulled out or disturbed. The turnin about the perpendicular axis may be effecte by known mechanism including a connection from the segment block 45 to a lever 52 for 54 which engages reciprocatin a rack bar teeth on the'ball head of thegripper carrying bar 13. This connectionmay be made yieldingiby the spring 55 and the extent of the movement imparted may be varied by adjust- .100 quired for lasting a shoe. Another advanfrom stock pulled as indicated by the arrows r in Fig. 7. Substantially the same result can be obtained, where plaiting in one direction only is re uired as in welt and turn shoes,by forming t e grippers jaws as shown in Figs. 4 and 5 with the rear edges in the same ,vertical plane as the oblique axis of rotation is located. By so doing the

parts

52, 54, 55 and 56 may be omitted as shown in Fig. 2 and the machine thus simplified. If the gripper carrying bar 13 is to be turned by said parts as shown in Fig. 1 that bar is formed to turn in a separate lock 58 which supports the elbow lever 42 and with which the overdraw rod 16 is connected.

The wiper which assists the grippers in laying the upper over the last bottom into position to be secured is shown as a swinging plate 60 fulcrumed at one end to a carrier 62 and ivoted at the other end to a slide 68 adapte to be reciprocated to swing the wiper forward and ack over the upper in time relation with the gripper actuating means. This wiper is used only in lasting the toe of the shoe and at other times should occupy a retracted position to ermit proper presentation of the heel and si e of the shoe. The position of this wiper is controlled by a cam slide 65 arranged to move endwise and having oblique walled notches which when they are opposite the members 62, 63 permit the springs 66 to retract the wiper. Seats between the notches maintain the wiper in its advanced position when the cam slide has been moved to cause the oblique walls to wedge the members 62, 63 forwardly against the tension of the springs 66. For thus shifting the cam slide 65 a lever 70, fulcrumed adjustably at 71 and operated from a groove in the edge of cam block 4, is provided with a wedge 72 having oppositely inclined side faces and means connected with the cam slide 65 is arranged to be set by the operator in position to cause the power driven lever to -do the work of shifting the slide. In Fig. 1.the slide 65 guides two

pins

74, 75 connected to opposite sides of a rockshaft 76 supported in an arm 78 which is sustained by the vertical shaft 80. The rockshaft 76 has an arm connected by a rod 82 with a lever 84 fulcrumed on the vertical shaft and adapted to be actuated by a push bar 85 which is guided in the knee lever or arm 86 carried by the shaft 80. The push bar and the arm 86 have cooperating shoulders and the bar is arranged to have enough lateral movement to permit it to be readily engaged with and disengaged from the shoulder on the arm.

A spring 88 is arranged to move the push bar out and to-thrust the pin 74 upwardly into the path of the left hand side of the Wedge 72 and simultaneously to withdraw the pin 75 below the path of the wedge. When this has been done the wedge in its next forward stroke acts through the pin 74:

to move the came slide 65 toward theleft, placing the notches therein back of the wiper carrying member 62, 63 and )ermitting those parts to be retracted by t eir springs 66. Inward movement of the push bar reversely sets the several parts causing the pins 75 to be placed in the path of the right hand face of the wedge and the latter to advance the wiper and compress springs 66. A movement of the push bar to the right after it has been pressed inwardly causes it to lock against shoulder on the arm 86 so that the wiper remains in its operative position until the bar is unlocked. In Fig. 2 a modified construction is shown in which the wedge 72 coiiperates with another wedge 90 on an arm 91 extending from a sleeve 92 having in another arm 93 a V shaped notch either wall of which can be engaged by the push bar which has a spring to'retract it. The arm 91 has .stop screws 94, 95 located to engage a swinging bar 96 connected to the cam slide 65 for moving that slide. The swinging bar 96 in Fig. 2 is also connected by a link 97 with a plunger 98 actuated through a lever 99 by a cam face formed on the rear side of the cam block 3. The link 97 puts the plunger into engagement with a. shoulder on the wiper actuatin slide 63 to cause the wiper to be moved while it occupies its operative position and said link withdraws the plunger from the shoulder to leave the wiper at restwhen the wiper is retracted' It will be observed that in both of the constructions the wiper controlling devices are set by an easily operated means but the actual work ,of shifting the wiper is done by the machine and the wiper can be rendered operative or inoperative independently of the plaiting' mechanism which is started and stopped by turning the vertical rock shaft 80. In the 110 on the wiper controlling cam slide 65 to turn the collar and disengage the slotted arm 102 from the lever, 70 when said cam slide is shifted to render the wiper inoperative. The stud 105 can be adjusted in a slot in the lever 70 to vary the stroke ofthe wiper independently of the stroke of the lever.

For fastening the upper tacks are employed at the sides and heel of the shoe and are fed from a raceway 120 by a separator 122 to a tack carrying block 124 secured to the front end of a slide 125 attached at its rear end to the lever 70. A driver 126 on a bar 128 actuated from the driver cam notshown on the shaft 2- is timed to punch the tack from the tack block into the shoe when the block is in its advanced position after which the block retracts to receive another tack from the separator. The use of tacks should be discontinued while the toe is being lever 86.
