- Borough of f Flemington, l\T.,-..,\y a corporation of New' Jersey f j AppIieanQ-Mayfis, 1940, serial No. 335,974v 1 This invention relates ytoj shoe rests and;v `is herein illustrated in itsapplicationtoltoe rests yintended foruse i-n lasting machinesof the type illustrated, for example, in United VStatesLet-` ters Patent No. 1,018,477, grantedFebruary 27, 1912, on an application.of-Matthias Broch.`

Machines of the ,type illustrated in the Brockr patent are providedwith toe lasting wipers which in the course of their operation have equalmovements toward each other,l and-in order for thek wipers to actv uniformly onV oppositefsides of 'the shoe, the toe of theA shoe mustbe-locatedcentrally with relation to thewpers.

It is` anfobject ofthe presentl invention to -provide a Vshoe rest which is adapted-tqlocate ,a shoe centrally relatively to toe wipersor other operating means.r With this object in view, the invention in one aspect thereof providesat rest comprising al plurality of members arranged to engage opposite side portions of a shoe in the machine, said members being yadjustable .toward and from each other to` accomodate different widths of shoes, `and adjustable asa unit widthwise of the shoe. In order that the illustrated shoe rest may conveniently be ,arranged to operate on both right and left shoes ofa given-size vand style, the-,illustrated ,machine is provided with a support furthe-shoe restgpa-nrd they-shoe rest and its support, in accordance witha further feature of the invention, are so constructed and arranged thatthe shoe rest may be'located` and held in any one of a plurality `of predetermined positions relatively to a shoe in the machine. As herein illustrataed,y the shoe rest is provided with a stem having opposite l which cooperatewith a locating member in a stem-supporting post to positionsof 180 l*displacement about the axis of the stem.

' While the inventionis herein illustratedin its applicationto toe restsfor use in lasting ma- -chines,'it is to be understood that the yinvention is not limited in "scope to toe rests or to .shoe rests for use in lasting machines but V is applicable -to shoey rests forguse in other typeswof shoe machines and to shoekrests which operate atportions otherthan the toe :end of then-shoe.

Y These and rother features ofthe invention will longitudinal grooves locate the shoe yrest in rated therein, the .toe portionl of a. shoe in the machinel being indicated bywbroken-lines;

i of the toe rest, partlyv'in section, the central rportion of vthe stem of the toe rest` being .brokenr their wiping edges.

V`the wipers is xedand unvariable and,lconse iquently, it is desirable that the toe portion of y Fig. 2..is an enlarged view'in front elevation away;, f, f

Fig-'3ds .an .enlargedA lview of one side of ,the

head of the toel rest; and'y Y Fig. 4 is a plan view, partly in section, showing thestem of the toe rest in its supporting post.

In Fig'l `a toe restembodying the features of the present invention is illustrated in `,con-

junction with thetoe'head of av lasting machine of the type illustrated) in the patent to Brock above referredto. yThis machine is provided with toe wipers `Ill which are operated by longi-v tudinal movement of a sliding shaft I2. Upon operation ofthe shaft l2, the toe Wipers advance longitudinally of the toe portion of a shoe in the machine,- and as they advance, theyY close` upon the shoevby pivotal movement about a point which coincides Withthe adjacent ends of` .The path of movementof the shoebe centered Widthwise thereof relatively tothe wipers inforder that the wipers rmay'operate uniformly on vopposite sideportions ofthe shoe upper. y Forcenteringthetoe portion of the shoe relatively.I to the wipers, the illustrated toe rest isk provided with upper-engaging membersy or. pads I4 which are preferably made of rubber or other resilient material and arranged to engage, opposite side portions-of the toe end of a shoe in the n machine. l

ended studs IB (Fig. 2) which swivel in upward K extensionsjlrrof slidesA 20 which are mounted in crosshead 22 at the upper end of a The' pads i4 are mounted on ball.-

slideways in la stem 24 mountedfin a support herein illustrated asa hollow post'ZKFig. 4)' extending upwardly from vthe bed of the machine. The swiveling movement ofthe studs I6 is limited by pins 21 extendingfrom4 the -`studs into round openings in the extensionsfl (Fig.v 2). The crosshead r22 n, extends widthwise of the shoe and is held against now be described with reference to fthe accom--y panying drawing and pointed out in the appended claims. n

In' the drawing:

Fig. 1 is a plan vview illustrating a portion lof the toe head of -a bed-lasting Amachine having the toe rest of the presentinvention incorpof opposite endportions of which are threaded re- I turning movement'by aspline 28 which enters a longitudinal groove 3l] in the stem 24. .r The pads Mare adjustable toward and from eachother tojaccommodatejdifferent widths yof shoes by turning a right and left threaded screw 32, the

snetively in the lowerA portions Vof `the slides 20,

the central portion ofthe screw being provided v with a head or knurled thumb-wheel 34 by which the screw is turned. The screw 32 is held in adjusted position by a spring-pressed plug 40 mounted in a bore in one of the slides 20, which bore communicates with the tapped hole in which the screw 32operates. The pad assembly including the slides 2U and screw 32 is adjustable as a unit widthwise of the shoe to center the toe portion of the shoe relatively to the toe wipers ID. After so adjusting the toe pad assembly, the assembly is secured in adjusted position by screws 3B mounted in the crosshead 22 and arranged to engage opposite sides of the wheel 34. If desired, the screws 3S may be employed to effect the adjustment of the pad assembly as a unit widthwise of the shoe. It will be understood that in so employing the screws 36, they operate alternatively against the wheel 34 as thrust members to move the slides 20 through their slideways in the crosshead 22. After so adjusting the assembly, if one of the screws 38 is spaced from the wheel 34, said screw is brought into engagement with the wheel to hold the assembly in adjusted position. The adjustment of the screws 3B is maintained by compression springs 38 which surround said screws and act against their heads. It will be understood that the pads I4 may be adjusted toward and from each other by turning the right and left threaded screw 32 without disturbing the adjustment of the pad assembly as a unit maintained by the screws 36. In arranging for lasting right-foot shoes, for example, aiter having previously operated on leftfoot shoes of the same size and style, the toe rest is merely drawn upwardly out of the post 26, then turned 180, and replaced inthe post 26. It will be seen from Fig. 4 that the stem 24 of the toe rest is provided with two longitudinal grooves on opposite sides of the stem which receive alternatively the spline 28 which holds the stem against turning movement.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

l. In a shoe machine, the combination with means for operating on a shoe in the machine, of a toe rest comprising members arranged to engage opposite side portions of the shoe, said members being adjustable toward and from each other to accommodate different widths of shoes and adjustable as a unit widthwise of the shoe.

2. In a shoe machine, the combination with means for operating on a shoe in the machine. of a shoe rest comprising members constructed and arranged to engage opposite side portions of the shoe, means for adjusting said members toward and from each other to accommodate different widths of shoes, and means for adjusting said members as a unit widthwise of the shoe.

3. In a shoe machine, the combination with means for operating at side portions of a shoe in the machine, of a shoe rest comprising members 4. In a shoe machine, the combination with means for operating at opposite side portions of a shoe in the machine, of a shoe rest comprising members constructed and arranged to engage opposite side portions of the shoe, means for adjusting said members as a unit widthwise of the shoe, and means operable to adjust said members toward and from each other without disturbing the first-mentioned adjustment.
