Be it known that I, WILLLAM C. BAXTER@ citizen of the United States, residing at Beverly, in the county of Essex and StateV of Massachusetts haveinvented certain new and useful VImprovements in` Shoe-Jacks;

- and ll do herebycdeclare the following to be a full, clear, and Vexact description `of the invention, such aswill enablel others skilledinthe artto which it appertains to makev and use the same. .-7

l The present invention relates to shoe supporting jacks and more particularlyto jacks which are employed in connection with ma` V-chines for leveling the soles ofl boots and shoes. It is desirable thata jackiof this type shallibe so constructed that it may accommodate shoes and long-legged boots of varying sizes and styles, that the adjustment may be readily accomplished'without requiring a high degreeVK ofskill, and thatwhen properly adjusted the jack shall' hold theshoe firmly during the operation of the machine.

The object of the present invention is to provide a jack of this typer which may be 'readily and accurately adjusted tofaccommodate with equal facility both shoes and long-legged "boots of widely varying sizes and styles and which holdsthe boot orvshoe fsecurelywhen positioned upon ther'jack.

v f W ith this object in view, the several fea' tures of the vinvention consist in certain novel features ofconstruction, combinations and arrangements 'of parts, the advantages of which will be obvious to those skilled in the art from the following description.

arm l5 .spaced away from and formed intev vgral 'with' the heel post. The adjusting member is retained against longitudinal "movement relative to the head llfby a collar '16 and a hand wheellsecured tothe mem- -berupon opposite sides of the head. 'With this construction, by aysimple rotationV vof .the adjusting member the heel post is moved -toand from the toepostto readily adjust thejack for different sizes of'shoes. V`With this type of machine they most'eliicient level--V ing action is secured'whenfthe shoe is supported inan operative' position with its 'sole lying substantially in' a vhorizontal plane, as whenthe shoevis supportedin this position the same pressure is exerted upon different 'portions of the, sole.: In the-'majorityr of 110 n *i lasts the depth of the last varies proportionately with the length, and to compen-V sate for this variation in depth the last block when adjusted for smaller sizes of shoes must have both an inward andl upy'ward movement; toward the toe post. Inv

the present invention this is accomplished the necessity of aV separate vertical adjustvment of the last block each time that the jack is adjusted for varying sizes of shoes.l

The toe of the shoe is supported Vupon a toe rest 20 which is detachably connected yso . support.

to a toe Vrest support 21 through-a vertical spindle 22 and a pair of depending ears 23 engaging with opposite sides of the toe Yrest A bodily vertical adjustment of the toe rest relative to the support is secured by a wedge 25 slidingly mounted upon the support and interposedr between the support and the lower face of the spindle 22, as shown clearly in Fig. 3. The wedge is adjusted horizontally to raise and ylower the toe rest by an adjusting member 27 threadedly engaging with the wedge and journaled in an arm 28 formed integral with the toe rest support 21. The adjusting `member 27 is retained against longitudinal Vmovement in the arm 28 and is pro- -vided with a'hand wheel 29 which enables Vit to be conveniently manipulated by the opthat the toe rest is adjustable about an axisV lying substantially in the work engaging surface of the rest. rThe rest is adjusted by a worm 35 journaled in the toe post and meshing with a gear segment 36 formed upon the under face-of ythe support 21.V The outer end of the worm 35 has a knurled wheel 37 secured thereto which may be conveniently operated to adjust the toe restv angularly without causing a bodily displacement of the work engaging surface of the rest. The upper portion ofthe toe post is provided with an inclined face 39 which is normallyV contiguous to the surface ofthe sole vand forms a receiver for the leveling roll in a manner well-known to those skilled in the art. Y 1

The heel portion ofthe last is supported by a last block 40 fulcrumed centrally upon the heel post at 42 and having the usual last spindle 41. As shown in Fig. 4, the last block is-supported by a'pair of flat plates secured in recesses formed in opposite sides of the heel post and extending upwardly to form bearings for opposite sides of the last block. The last block is rocked to clamp the shoe uponthe jack by an actuating rod 46 slidingly mounted in the heel post and bearing upon the under side of the lastblock at one side of the fulcrum. rllhe rod 46V is moved in the direction of its length to impart a clamping movement to the last block by an actuating shaft 47 journaled inthe upstanding arm 15 and extending into a position conveniently accessible to the operator. The'actuating 'shaft 47 has a beveled gear 52 secured to its lower end the last block vopposite the rod 46, and a spring beneath the plunger.

In leveling machines of the rolling pressure type it is customary to applyl the pressure successively to opposite margins of the sole and this transference of the pressure tends'to rock the shoe laterally upon the last, which movement not only enlarges the last pin hole and prevents the firm clamping of the shoe, but impairs the efficiency of the levelingy operation. To hold the shoe firmly duringv the leveling operation the jackl of the present invention embodies a clamp which vtightly embraces the heel portion of the shoe and rigidly maintains the shoe in upright position7 preventing 'any lateral movement of the shoe due to the action of theileveling device. i The heel clamp is supported upon theV upper end of a rod 65 fulcruined at 66 on a lateral extension 67 of the heel post. Theclamp is freely movable into 61 which engages .an operative position and is positively locked in this position by a pawl 69'slidingly supported upon the heel clamp and engaging with a stationary'ratchet toothed plate 70. 1The plate 7 0 is fastened Vin any suitable manner to an arm 71 extending from the arm 15 and secured thereto by bolts 72. The pawl 'and ratchet are disengaged to remove the heel clamp from the shoe by a ourved'finger lever 75 pivoted upon the heel clamp at 76 and loosely connected to the pawl by a bolt 77. The opposite endof the boltis connected to vet j sides of the heel, each of the clamps being' f faced with suitabley yielding material to avoid marring the upper of the shoe. rlfhe a tension spring 73 which normally serves to press the pawl into engagement withtlie ratchet plate. The linger lever projects into a position convenientlyV accessible to the hand of the operator sothatthe palwl may be disengaged and the heel clamp swung f back into an inoperative position by theLA employment of one hand. Thevheel clamp shownin the illustrated embodimentof the invention consists of a plurality of separate clamps engaging with the back and sides of the counter, and to` enable theclampto iit 1 varying sizes and styles of lasts it is capable of a bodily vertical and angular adjustment .and` an adjustment :of the side counterclamps toward and Vfrom one another. The

counter-clamps aremounted upon ahead `7 9 which is providedwith a lstandard 7 8 rotatably mounted in a support and normally clampedv in the support by a transverse clamping bolt 8l having a recessed portionV -engaging with the side of the standard,

as shown clearly in Fig. 7.. The bolt 81 is .provided with a hand wheel 8,2 threadedly connected to the clamping bolt and arranged to draw' the side of the recessagainst the standard tol clamp the standard intolposi-V tion in a manner well understood'. The clamping head is adjusted vertically -by a screw 83 threadedly engaging with 'the head and provided with a knurled operating nut 'SAQ VThe screw is retained against longitudinal movement by a VT-shaped head .-85 which projects into a correspondingly shaped v curved recess formed in the support 80,

which, as shown in .Fig` 5, is of greater length than the width of the "El-shaped head to allow a bodily angularadjustment of the heel clamp. The counter-,clamps are shown clearly in Fig. 5 and consist of a clamp 90 engaging withlthe back of 'the'heel and a pair of clamps 91 engaging with opposite clamp is formed integral with thehead 79 and each of the clamps V91 is'- pivotally supported upon an arm 92 formed as a bell cranklever fulcrumed upon the head at 94e and having atoothed segment 95 meshing with an adjusting worm 96. The worm 96 is formed upon the inner end of a shaft 97 journaled in the head 79 and having a hand wheel 98 secured to its outer end by means Y of which the shaft is rotatedto cause a movement of the clamps 91 toward and from one another.

The preferred mode of operationl of the jack is as follows The shoe to be operated upon is first positioned upon the last block with the upper of the shoe or long-legged boot, as thecase may be, hanging down loosely around the heel post. The heel post is then adjusted relative to the toe vpos-t to properly seat the toe of the shoe upon thel Vtoe rest, and the shaft'l? is then actuated toclampV the shoe firmly. in'position on the v jack; Before clamping the slice in position the toe rest may be adjusted angularly, if so desired, to cause the toe, of the shoe to engagey closely with all portions of thetoe cap., After theshoe has been clamped upon bthe jack the heel clamp is swung inwardly V by vthe Voperator until the counter-clamp 90'. i engageswiththe'back vof the heel,.in whichl position it lis automatically locked in -posi- ',-tionrby the p'awl and ratchet'locking mechaj nism. Priorfto this locking of the clamp in position, it may be adjusted either verticallyA for angularly "to properly engage with the -heel portion of the shoe.l After the heel clamp is properly positioned, thehand wheel g98is manipulated to move the side counterclamps Vtogether yaiid" giip `the sides of. the
