o all rwhom it may conoerm 't v Be it known that I, Fnnn Ems, a citizen ci' the United States, residing at-St, Louis, the State oiMissour have invented ceriilfn Im, irovements in olddowns, of which ,the following4 description, in connection Y th the accompanying drawings, is a specication, like reference characters on the "2f-*drawings indicating like parts in the several l figures. 1 f

,Ty This invention relatesl to hold-down devices for use in connection with bed lasting y machines, such, for exemple, as the I welli-lm'own kcommercial Ideal lasting machine lo which is shown in the United States patent 'izto Grandy No. 552,834, to which reference muy be had for e description off the machine in general. v A

.he present' invention is embodied in an improved form of hold-down foot. Prefer- "nbly andes shown, the hold-down foot com- -priseseplate which is oi substantially the shapeofithe toe portion of an innersole and sndcpted to iit closely egeinstl the rear face ofthe raised lip or rib which exists on the eiinersole of e, Welt shoe., saill plete being ga :,tpted toisustain the rib against the lateral bressure of the. to@ lsstin wipers as ,they lare operated `for working t up er into the 39 angle formed by the feather and rib of the innersole.

As another feature of lthe inventiomthe yrib engaging portion of the footfplete is 'formed by the edge of the plate only which iscshown as turnedv downwardly at an angle to the plane of the sole to form a flange and is dressed 0H so als to rest evenly against the' face of the innersole, preferably with a substential space between the face ofthe innersole and .the body of the plate. This formation of the hold-down foot plate adopts it l for use also as a feather clamp. In such use it is positioned first forwardly of, or outi side 5f, the rib and upon thefeather edge of downorkthe lestl so as' to redtlce danger of the feether'being ece, by 'the Wi' i rs .in their pward'mov" n a'nd lity away from the' stntally rigid, as com wed Wlththe innersole where it maintains the featherv thinness of the down-turned edge or flange portion of the plate in engagement with the Alfeether enables the wipers to be forced in over the edge of the last and over the feather of the innersole sufficiently Vfar to hold firmly the upper in lasted position before the hold-down plate is withdrawn from engagement with the feather. When this, is donc,

the wipers may he advanced farthertocrowd the upper into the angle and into position to be secured hy Wiring-or otherwise. When the plete 'as withdrawn from the feather and prior to this further movement of the wipers theplate may be again positioned behind the lnnersole rib to Sup ort it during the final inward movement'ov the Wipers.

As l am advised, it is new with me to provide a, hold-down foot which is constructed and arranged so tha-tit can be used alternatively or successively outside of e welt innersol'e lip orrib as a feather clump extend` in around the curved end of the toe or insi e the rib as an abutment to resist lateral pressure aga/inst the rib at one or both sides as well as at the tip of the toeend of the innersole.

` The outside edge contour of the hold-down and another advantageous use of this foot is as a binding wire seat crease former in. cooperation with the wipers. In this use thefoot is positioned upon the feather just outside the innersole rib and, it being thin, v the wipers are advanced and mold the upper against the outer faceof ,the foot to produce the '.wire segst crosse, The foot .being sul tre rib of the nner'sole, the crea, is more definitely forme then ithles heretofore been formed b etweenthe Wipers and the rib. The vwipers are thenfbacked nwe slightly from the .crease thns formed to a low the binding wire to bepla'eed i, the seat for it and to ermit the Afoot to be withdrawn from the. esther jandppsitioned inside the rib where it may serve es an abutment for the rib. The wip# ers calin then be agam edvenced to engage the :vire and press it into its sent crease end there after, and here is tine of the important ad- ,vantages for this` feature Yof the invention, to force the seat crease Ainwardly toward and against the innersole rib and thus substan- .tiall tighten the upper. This action is particu arly advantageous atthe sides of the tip of the toe, or the corners of the toe, where it is most diicult to overwork the upper without wrinkles'or looseness.

As a further feature of this invention, with which may or may not be used the foregoing features, the foot plate which constitutes the pressing member of the hold-down is supported 'for lateral movements of adjustment or adaptation to the work on an arm which is movable over the bottom of a shoe sustained in position to bellasted in the machine. There 1s a pivotal connection between the foot plate and the supporting arm which is preferably located so that `it will be over substantially the center of curvature of the toe end of the innersolewhen the foot vplate isfin operative position. By this ad- )ustable mounting` the foot plate may be 25 swung toward one side or the other side of its supporting arm to enable it to fit innersoles for right and left crooked lasts having toes of approximately symmetrical curvature. It is most important that the foot plate form an abutment for the innersole rib at the outer side of the toe because it is at this side of the toe that most difficulty is exiIiierienced in properly lastin f the upper rmly against the rib. There ore, while'the foot plate may most advanta eously be made to fit the shoe exactly and e changed for different sizes of the same style of last, the same foot plate, mounted 'as her'ein described, may--be used with 'very satisfactory results for larger shoes than it accurately fits, this being donev by positioning and swinging it over against the rib at the outer side of the toe of the right or left shoe which happens to be in the machine. `To make thisclear thisuse of the-holdvdown foot is illustrated in the accompanying drawings. t

This invention is particularly advantageous when used with machines of the Ideal type abovereferred to. in which the alinement of'the toe and heel heads and of the wipers carried thereby is fixed, and conse- (fluently the longitudinal median line of the orepartof a last which has considerable swing will extend at a substantial angle to the line connecting the center of the toe head, or the toe wipers, with the center of the heel head, or the heel seat wipers, the said median lig'ne extending to one side of the line joining the end centersl of the last for a right shoe and to the other side for a left shoe. Means for limiting the movement of the plate about its pivot is preferabl provided and may jconveny iently take t e form of a slot and pin connection, the slot being formed in the plate and being struck from the pivot of the plate as a center and a headed pin being passed through the slot and secured to the sulpporting arm to co-act with the ends oft e slot for limiting the movement of the plate in either direction.

These and other features of the invention y/will ap ear more fully from the following detailed) description in connection with the accompanying drawing, and will then be more definitely pointed out in the claims.

Figure 1 is a plan view of a lasting machine of thee/Ideal type as disclosed inthe patent above referred to providd with the preferred embodiment of the invention; Fig. 2 is a perspective view, partly in section, showing the manner of attaching the hold-down foot to the hold-down arm, the foot and its supporting arm being shown by full lines detached from their swinging carrier, and by dotted lines in operative p0. sition; Fig. 3 is a longitudinal section of theforepart of a shoe 'showing in side elevation the hold-down foot applied thereto:

In Fig 1 which is a plan view of a ma- 90` chine of the Ideal type, the heel and toe A heads are represented at A and B` respectively, the longitudinal axis of the machine passing centrally through them both. The character 2 indicates the ySwingin carrier by which the hold-down foot 30 and its supporting arm 20 are moved over' the bottom of the shoe sustained in position to l s 1'usted in the machine. The hold-down carrier is mounted to swing on a post 1 and has a 100 vertical movement with the post. This l post constitutesthe operating means for the hold-down and with 1t is connected a usual actuating treadle and a return spring, and preferably also a lockin latch as. shown for example in British atent No. 19,512, 1911. The hold-down foot 30 which is connected to the arm by complemental formation of any suitable character permitting lateral Yswinging movement ofthe ffoot about pivot 32. Such movement is limited, and the foot plate is further secured to,the\ arm 20, by a headed stud 36l and curved slot 34 connection between the arm and the plate in the rear of the pivot 32, the slot lltbeing curved in an arc about said i'vot 32.-

Y The hold-down foot is shap to lit closely against the innersole rib at the tip of the toe and is contoured to form an abut-'1. ment for the inner face of the rib both at 130 the tip and' at one or hath sides ofthe tip of the toe for supporting'said rib a 'list the action of the llasting wipers. The olddown foot is advantageously hollowed on its work engaging lower face thus affording i a concentrated bearing of its edge upon the innersole closely adjacent to the innersole rib and unaffected by irregularities in-the surface of the middle portion f the inner- I sole. As shown, this foot comprises a plate to formk a down turned flange 31.

its ges bent' at the front end and slidles is formation permits the foot plate to be applied either with its bearing fla-ngeinside the innersole rib as shown in the drawings or outside of saidrib Where it will press down upon theffeather of the innersole to prevent the 'feather from being lifted by the wipers. if the shoeds large for the foot plate, as will in practice often be the caste,

the foot plate is made to abut against the rib at the tip of the toe and is swung into engagement with the rib at the outer side of the toe, as shown in the drawings, where the rib most requires support. In Fig. 1 the foot plate 30 is shown in the position it would assume upon a right shoe, the right shoe being shown in full lines in that figure in which the swing of the last is indicated by the line @1w-R which is the longitudinal median line. of the forcpart extended. In dotted lines in the same figure is represented the outline of the leftshoe, the longitudinal median line of the forepart of which extends in the direction of mv-L. It will be seen that the line .fr-R is inclined toward the axis from the other side and that considerable movement of the plate 30 is required to enable it to fit closely the toe portion of a right or left shoe where the swing of the last is considerable. To provide this movement the plate 30 is pivoted to the arm 20 at 32, which point is substantially at the center of curvature of the extreme toe portion of the plate. The plate 3() beingl freely pivoted at this point automatically assumes ay position against the rear face of the rib of the innersole when pushed forward against it by rotation of the earrier2 about the vertical axis 1. The arm 20 which supports the hold-down plate f3() is perferably resilient and the stud 4 by :which it is pivotally attached to the arm 2 has a, roughened head G, Fig. 3, which is adapted to engage the innersole when the engagement of the piate 30 1with the shoe has caused the arm 20 to yield. The stud 4 is flattened on its sides at 8 and maintained in fixed position in a hole in the aim Qrhy a spring-heldpin it) which is forced outwardly into a hole l in the stud. The stud is passed through a plate 14 havin lips 16 bent up at the edges thereof. The arm 20 is provided at one end with a hole 22 having an open slot Q4 leading therefrom and. is assembled upon the end of the hold-down arm by pushing the slotted end upon the stud in the direction of the flattened sides of the stud until the stud rests in thi` opening 22 when the arm 20 may be rotated about the stud. The lips 16 of the plate 14 are arranged to rest against opposite sidesfof the arm 20 and by reason of the tapered formation of the arm 20, Fig. 1, it

cannot be pulled from the stud even when in line with the flattened sides thereof until it has been sprung over the lips 16.

For different styles of shoes differenthold-down feet may be provided, the construction shown providing means for readily detaching one foot and its arm 20 and attaching another. T effect this the operator has only to insert a pointed instrument between thev plate 14 and the spring arm 20 and separate them vsufiiciently to disengage the lips 16 from the arm 20 so that the plate 14 andparm 20 may be swung relatively to each other about the stud. The arm 20 may then be detaehed by rotating it into alinement with the hold-down a-rrn, Fig. 2,.and pulling it outwardly in the direction of said arm, the flattened sides of the stud then permitting it to pass through the slot 24 of the arm 20. Other hold-down feet may be attached to the hold-down arm by reversing the movements described for. removing the foot.

The use and operation of the described embodiment of the invention may be readily understood by those skilled in the art with out further description, and it is also apparent that various modifications of the device as described may be made without departing from the invention.
