LASTING-MACHINE.

I Patented Dec. 10, 1907.

Application filed February 16. 1906'- Serial No. 301.449.

To all whom it may concern:

Be it known that I, JAMEs OAVANAGH, Jr.,

, a citizen of the United States, residing at drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines I and particularly. to the type of lasting machines employed for working a shoeupper over a last and securing it in overworked position by repeated operations of the ma chine applied to different parts of the shoe.

. An example of this type of machine is shown in United States Letters Patent No. 584,744, p

' certain portions of the shoe, such'as the toe,

June 15, 1897, and the present invention is herein shown as embodied in a machine of similar general construction. The machine shown in said patent is designed to secure the successively overworked portions of upr temporarily to the innersole of the shoe y means of tacks which are held in a raceway and are taken therefrom by a tack separator which delivers them-to a tack carrier having a tack opening or pocket located near its front end. In the operation of the ma-. chine shown in that patent the tack carrier is advanced over the edge of the shoe during each complete operation of the machine to present the tack held by it in position to be driven, and a driver is arranged to force the tack from the carrier into the work when the carrier has reached the limit of its movement over the shoe. Preferably also a presser is provided which is actuated inwardly over the portion of overworked upper to be secured and, when working upon Goodyear or welt shoes, pressesthe upper down upon the marginal portion orfeather-edge of the innersole and also, as it advances, presses the upper materials inwardly against the shoulder or lip with which the innersole of'a welt shoe is'provided. The presser thus acts to force the upper' materials into the angle of union between the lip and feather-edge of-the innersole', in which plosition it is subsequently secured by stitc 'ng which passes through the lip of the innersole, the over- -worked upper material, and a superposed welt, as-is well understood. \The presser above'described may be mounted and actuated in any suitable way, but as herein shown itis attached to the lowerface of the tack carrier and is advanced and retracted with said carrier. It is desirable that the tack contained in the carrier, which is tobe driven through the upper material and into. the innersole, be inserted at the angle of union between the feather-edge and the lip of the innersole in order that it may hold the upper material in proper position until it is permanently attached to the lip in a subsequent operation. In order that the tack contained in the pocket of the carrier may be drivenin said angle of union, the end of the tack car ier is necessarily somewhat in ad-. vance of the presser. The end face of the carrier consequently presses the upper slightly over the lip of the innersole when the carrier is in its most advanced position. In lasting which require to be plaited for taking care of the fullness of the upper materials,apresser is employed which is shown in the accompanying drawings as a thin plate and will herein be sometimes referred to as. the thin ipresser to distinguish it from the presser, rst described, which is relatively thick and will be sometimes herein. designated as the thick presser It is the general practice at the present time to employ wire for binding the upper in overworked position on the toe of welt shoes instead of drivin tacks for that urpose. The machine of said Letters Patent has been equipped with means for presenting wire to be used for binding. the upper, one form of.

such wire-presenting means being shown in United States Letters Patent No. 696,740, granted April 1 1902. in the latter Letters Patent by which the delivery of tacks may be suspended while wire is being used. In the use of the machine thus equipped the wire, which is held under tension, is secured to a tack at one side of the shoe and drawn about the toe of the shoe asthe lastin proceeds to bind in overworked. position/the successively lasted portions of upper material and, finally, is secured to a tack at the opposite sideof the. shoe. The thin presser above mentioned is employed for pressing the upper material firmly into the angle of union between the lip and feather-edge of the innersole and forms a seatfor the wire in the angle between the portion of upper which lies over'and is parallel with Means is also shown Q 40 cause the thin acting end of the thin presser seat and hasno tendency to ride up over the lip into aposition which would permit the overworked upper to slip back and slackenp The fullness o the upper material at the toe 1' oausesits Tee-edge to tend to wardly toward-the edge of the si oe, thereby increasing the security with which the wire "is seated in its holding position.

.It is-found in, practice that thereciprocat- 1- pack 'carrier, which in its tack delivering position extends slightly beyond the outer ,faceof the lip of the innersole,.bends the upstanding edge portionof upper material in wardly over thehp and, therefore, tends to lift or str'ai 'htenup the portion which-has been pressed-into the angle of union between the lip and feather-edge. This action on the upper displaces the wire slightlyfrom its seat an permits the overworked upper material to slip back so that the toe of the shoe is not 25, as tightly lasted as it should be. In view of this difficulty, and the fact that the tack carrier is not needed while that portion of the shoe is being lasted which is, secured by wire insteadof, tacks, means is provided in accordance with one feature of this invention for discontinuing the movement of the tack carrier into-position to engage the upstand ing flangeol upper material. In the embodiment of the invention herein shown the movement of the tack carrier is entirely suspended by means under control of the opera tor. The thick presser, being mounted on the earrier, of course has its movement discontinued when the operation of the tack car nor is suspended. This is advantageous beforms a better seat for the wire when it alone forces" the upper material into the angle of union between the lip and feather-edgeof the inner-sole thanwhen the blunt-ended thick presser also acts upon the upper material. 'lhethick resser, however, is more effective than the t .in presser in lasting the sides of the shoe and particularly inlasting the heel portion of the shoe, in which the stock to be pressed over the ed e of the last is bulky and usually stiff. It wi I now be understood that the thin presser is needed While the portion of the shoe is being lasted which is secured by wire and that the thick resser. and tack carrier are needed While t ose portions of the shoe are being lasted which are fastened by tacks] Another feature of the invention,

therefore? consists, providing means renderingsone of said pressers inoperative when the other ip'res'ser is operative; Each presser is. herein shown as detachably con nected with a source of power by which it is operated and meansis prov1ded fOr-simulta neously disconnecting one. presser from its roject out "tack carrier, the thick presser, and the driver creme operating means when the other. presser is connected to its operating means so'that the change from one presser to the other is made by a single act of the operator Arrincidental advant'agewhich results fromm'c'ving the tack carrier into its retracted position is that it is thereby located Where it does not interfere with the operation of any other parts of the machine. In the normal operation of the machine the tack carrier advances before the grippers of the overworking mechanism release the upper and when lastin the inelastic stock which is frequently foun at the toe of the shoe where the upper material includes, the toe stitlenings it frequently happens that. the grippers, which are yieldingly actuated, occu y a position near enough to the edge of I the s oe to be struckand marred bytheQadvancing tack carrier. v j r In the machine herein shown as embodying 8,5 the invention the tack separator is arranged to be actuated by mechanism including apart. carried by the tack carrier andit of'oourse follows that the movements of the tack sepa rator are stopped and the delivery of'tacks to the tack carrier isdiscontin'ued when the-4; movement of the tack carrier is-suspended. 'A further feature of the invention consists in providing means by which a normally op-' erative tack driver may berendered inopera- 9o t ve while the machine continues in operatlQIl for lfastmg portions otthe shoe in which it is not desired to have tacks inserted-by thedriver. It will be obvious that the driveris not needed while wire is being used instead of tacks for securing the upper in overworked position, and inasmuch as its actuation causes some noise and also wear, as well as vibration of the machine it is advantageous to render the driver inopera'tivewhen. tacks are not to'be driven. in the machine herein shown the driver is actuated by a cam which raises it against the tension of a spring that imparts to the-driver its downward stroke; As illustrated, means is providedun'der control of the operator for securing the driver in its raised position while portions of'the shoe are beinglasted which are to be secured by other means than tacks and for-releasing the driver again when tacks are .tobe driven.

Preferably the ineansifor rendering thedriver operative or inoperative is connected with the means for controlling the operation eithe 7 tack carrier and the presser so that the open ator may by a single adjustmentirender the inoperative and. the thin presser operative When it is desir" to last a portion of the shoe which is to heag'ea-u gdlb wire and Tandems said driver, tack: i- 2; and thickpressef "operative and that-hm presS9piin p ti t when-the portion of'the shoe to be secured by-' tacks is about 'tob'e lasted.

h'leohanism 1s provided"inthe machinefor imparting to the grippers appropriate move- 'l3o ments for causing them to plait the appear when the toe of the shoe is being lasted, and as herein shown, this mechanism is connected. with the controlling mechanism above mentioned so that it is thrown into operation when. the thin 'presser is operative and is thrown out of operation when the thin presser is inoperative. j i

In lasting the heel of the shoe the grippers are not employed because the uf iler is not so supported at the heel portion 0 t e last that it would be stretched if it were pulled by the .grippers, and all that is required of the machine is for it to conform the upper material closely to the contour of the sides of the last and to bend it over and secure it to the innersole on the bottom of the last. For these purposes the shoe is pressed laterally against an edge rest having a face of sufiiciently vertical width to present a substantial bearing for the side of the shoe and the upper mate- .rial is bent over the edge of the last and pressed into position by the reciprocating thick presser heretofore mentioned. The. fullness of up er material bent over the convex edge of t 1e last forms crimps-or puckers which it is desirable should be pressed as smooth and flat as ossible. It is found in practice that in lasting the heel of a shoe the upper material stands away from the last more or less at the side of the path of-the tack carrier toward which the lasting proceeds and that the reciprocating presser does not, for this reason, work the upstanding edge of the material directly inwards as it should do. As a result the upper is sometimes not conformed accurately to the sides of the last at the heel and sometimes an extra fullness of upper material accumulates on the side toward which the lasting proceeds. It is also found that the crimps or puckers are formed. between the path followed by the pr'esser in one advance and the path followed by it in its next advance, or between two adjacent tacks. The crimps formed in this position are not iessed down as smoothly as they are -when t ey are located in the path of the presser-as, for example, near the tacks. In view of these conditions I have provided an improved work gage or edge rest which is'so formed that it can conform the upper to the contour of a curved side of the last. As herein shown the edge rest is constructed to conform the upper to contour of the side of Lhe last whether more. or less convex or concave, as well 61:5 to a straight surface, and it serves to hold the upper snugly against the last at the point adjacent to the advance side of the presser where it has heretofore had a tendency to stand away-from the side of the last. The edge rest thus positions the upstanding edge of upper material in conformity with the contour of the side of the last and where it willbe'bont squarely over the 65 edge of'the last by the reciprocating presser.

PAS shown, the edge rest is provided with a flexible work-engaging head to enable it to adapt itself to the contour of the" side of the last. The head of the edge rest may conveniently consist, as illustrated, of two face plates arranged edge to edge and pivotally connected to a support at opposite sides of the line of separation between them. .This

construction enables the platesto turn indendently in conforming to the contour of the work. The pivotal connections between the plates and supports are shown as located near the outer sides of the path of the presser and thcrefore'the rest presents a rigid bearin to the side of the shoe at these two points. when the upper is thus held by the rest the reciprocating lpres'ser forces it into desired position and t e crimps or uckers are usually formed adjacent to w ere the tack is driven and are l-aidvery smoothly by the presser. I

Another advantage of the improved edge gage is that the pivotalconnection'of the face plates to the support. at pointsspaced apart enables theadjacent edge of the plates to re cede or yield when the work is presented in These and other features of the invention,

including certain details of construction and combinations of parts, will hereinafter be more fully described and pointed out inthe claims.

reason oi its form and its greater strength for pressing theupper materials into lasted po. sition at the sides and especially at the heel lit isalso found that the move Inentof the tack carrier intoits advanced position when the upper material is bein se' curedbywire is attended by certain dlsadk vantages. The most important disadvam.

e is that the tack carrier advances as hereta to ore explained to aosition irnwhich its ifeatherrcdge and lip I unseat the wire so tn front edge contacts wit the u standing upper material on the outer side 0 the lip of the mnersole and oends the upper materlal over the lip. This bonding of the up or material tends to pull it out of theangle lie-tween. the of the innersoie and'fto at the wire holds the up per, less securely and sometimes permits it to slip-back towardthe edge'of the last so that the shoe is not lastedastightly as it should be. Another disadvantage incident to the continued movement of the tack carrier and,

thick presser at times when they are not needed is that useless wear of the moving parts is occasioned thereby. In accordance with another feature of this invention means is provided for preventingth'e tact carrier from advancing into a position where it'tends to displace the overworked upper materials,

and, as herein shown, this means consists-in mechanism for disconnecting the tack carrier and thick presser from their driving mechanism. While this may be accomphshed in various ways, the machine herein illustrated s provided with means for disconnecting the cam 88 from the driving shaft D. The cam 88 is shown as loose on the driving shaft and 1n the construction illustrated'ln F1gs. 2 and 11 is provided with, a device shown" oted, spring-pressed latch- 10*adapted to en;

gage with a notch in a collar 12 which is's'- cured to the driving shaft. When the latch is seated in the notch ofsaid collar the cam 88 is rotated. with the shaft andthe tack carrier and thick presser are reciproca'ted, as has been described. For the purpose of disconnecting the cam from the driving. shaft means is provided for withdrawing the latch from the notch in the collar 12 and preferahly for arrestingthe cam 88Jat apoint in its r rotation atwhlch the tack carrier and thick presses occupy their retracted positions. To

The. dGYlCQlfi serves by its frictional engagement with the spring-pressed latch to stop the rotation of t 1e cam 88 immediately after said cam has been disconnected from the collar on the driving shaft.

In thisconstruction the cam is provided with a springresscd pin 15 ada ted to enter-a suitably ormed pin hole in t is collard Zfor normally connecting the cam to the driving shaft. The pm 15 has a stud 16 which moves in a slot in the periphery of the cam and is adapt ed for engagementwith a comhincddisconheating device and brake. 17, shown as -mountedon a rockshaft lfl, which inpractice wiil he supported: in hearings in the frame Bf 'ihe rockshaftis provided with a segment gear 19 "engagement with a segment on an arm 20 secured to the vertical rockshaft 71.' Movement of. he vertical rockshaft in one direction will throw the disconnecting device and brake 17 a into the path of the stud 16 so. that as 'the'stud moves with the rotatingcam it willengage the inclined face of the device'ili *and'fbe moved to the right, thereby-Withdrawing the pin 15 from engagement withthe collar 12. The thick end of the tapering ortion of the device 17 acts as a brake. an arrests the rotation of the 'cam sothat the tack carrier is stopped in its retracted position. I

The devices for disconnecting the cam 88 \from' the driving shaft are preferably arranged on the rockshaft 71 in such angular pcsition'with relation to the devices which control the movements of the thin presser and the plaiting mechanism that the tack carrier, thick presser'and the tack se arator will be rendered ino rative when t ethin 20- presser and the p aiting mechanism -are rendered operative' The operation of the tack driver during the eriod when wire is being employed instead of tacks for securing the upper'in overworked position is unnecessary and not only causes useless wear, but occasions noise whlch 1t 1s desirable to discontinue. The machine 1s, therefore, provided with means for rendering the driverinoperative while those portions of theshoe WlllOll are secured Wire are being lasted, and, as herein ustrated, this is done Without interrupting the operation of the driver actuating cam. In the machine shown a. latch 21 is arranged to engage the driver bar and hold the latter at substantially the limit ofthe upward movement imparted to itby the cam 91.- The driver bar is shown-as provided with a notch 22 hich receives an inwardly projecting end of the latch 21. The latch is shown as mountedlooselyg on a shaft 24 and acted upon by a spring 27 for swinging it in the direction to engage. the notch-on t e driver bar.

. The rockshaft 24 is provided with a fixed collar'28'having'a shoulder to en a c with a stud-29 on the latch. The roc has a second" collar 30 having an arm to which is pivotally connected a link 31 ere tending to an arm32 on the vertical rock shaft 71} The arm 32'is'secu1'ed to the rock-'- shaft-in such angular relation to the devices for-disconnect" thetack carrier, the tack separator,-and t .e'thic kpresser from'their driving mechanism andthe devices for controlling the movementof the thin presser and the plaiting mechanism that the latch is heldout, of position for engagin the driver when the-tack block and the tee separator I are operative 'for presenting tacks to be Q0 gri'ven; The position of the arm 32 on the ockshaft 71 is such as to permit the latch 21 Y to engage the driver and render it inoperative when the tack carrier and tack separator are rendered inoperative. It is to be noted .65 that the latch 21 isyieldingly actuated into aft also position to engage the driver so that it presents no obstacle to the movement of the rockshaft 71 at any point in the cycle of operations of the machine. It will also be 0 served that the device 14 may be moved at any time during the cycle of operations of the machine into position to cooperate with edges to the front end of the arm v10.;eigThe I plates each have a limited amount of free movement about their ivots, their movement in one direction be ng limited by contact of their adjacent ends with the end of the arm 10 and their movemcntfin the opposite direction bein limited by sto s 46.

This construction 0' the edge rest ena les it to present an approximate y uniform hearing against convex, cpficave, or straight portions of the side of a ast and is particularly useful whenlasting the heel of a shoe where the upper requires to be conformed by the edge rest to the convex contour of the side of the last. The edge rest constructed as shown presses the upper against the side of the last at the advance side of the path of the reci rocating resser where it normally ten s to stand ack from the last. The rest thus holds the upper inproper position to be acted upon b the presser and forced squarely inward and "Killed or crimped. The pivotal connections of the plates 41 to the supporting arm at points spaced a art as shown insure the presentation an pressure of the shoe always against the central portion of th -gage and therefore in redetermined relation to the gage and to t 1e working parts of the machine.

in the operation oi the machine, the heel and sides of the shoe will be lasted in the usual manner, the shoe being held in the hands of the operator or supported by a jack if desired and pressed against the edge rest, the acting face of which will ada t'itself to the contour of the different portions of the shoe presented to it. After. the upper has been worked over the last and secured by tacks to the innersole'on the sides and heel,

tacks will be inserted artiallyinto the shoe bottom at o osite si es of the toe, and the machine wil tor to secure the en of the binding wire to one of the tacks. Before re-starting themachine the-operator will shift the knee lever to turn the rockshaft 71 in the direction to disconnect the cam 88 from the actuating shaft 1), to permit the latch 21 to engage the driver e stop ed to permit the operamovements to the grippers.

bar 90, to move the cam plate 23 for'forcing the thin presser into its operative position andtoput the plunger 42 into positionto actuate said thin presser, and also to render operative the mechanism fo'r giving plaiting All these adjustments having been effected by a single movement of the rockshaft, as before explained, the machineis restarted and thereafter the successively overworked portions of upper material are forced into the angle of union between the lip and feather-edge of the innersole by the thin presser and are bound in lasted position about the toe ofthe shoe by the wire w. When the lasting of the toe is completed the machine will be sto ped and the wire will be secured to the tacli on the side where the lasting operation is ended. The knee lever will then be shifted. to turn the rockshait 71 in the direction for restoring adjusted by i t, and the machine is" then ready for lasting the sides and heel of another'shoe. t5 Having explained the nature of the invention and described a construction embodying it in one of the best forms now known to' me,
