To all whom it may concern:

Be it known that 1, JOHN Gnonos PooL, a. citizen of the United States, residing at Lynn, in the county of Essex and State of ltl'assachnsetts, have. invented a certain new and useful Improvement in 'Machines for Making Wooden Heels for Boots and Shoes and the like, of which the following is a full, clear, and exact description.

The object of this invention isto provide a jack for use especially in connection with the improved machine for making or turninglvoodon heels for boots and shoes, expeditiously, accurately and economically, with the least possible manual. labor or sn pdrvision on the part of the operative, and in a prartically automatic manner, as set forth in the case filed May 15, 1915, Serial No. 28,465, of which case this case is a. division in conformity to the requirement of the Patent Office.

The invention consists of a jack, more especially designed for use in connection with the controlling and cutting mechanism -of the parent case referred to, which is adapted to admit of the ready and accurate placing of the work and its equally ready removal, and in which a lover mechanism is used for clamping the work in the jack, said lcvrr mechanism including a clampingshoo carried by the jack-head and alinod with the work-rest and connected with a rlampingdm r which is yioldingly supported in the jark-hoad, and a clamping-lever for operating said bar and through it the shoe, as T will proceed now to explain and finally claim.

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, F ignro 1 is a side elevation of the jack, and showing also the cam-tracks of the machine of the parent case herein referred to. Fig. 2 is a front clmntion. Fig. 3 is a partial vertical section Fig. 1 is a perspective view of one ofthe clmck-pirvcs detached, looking at the inner side. Fig. 5 is an elevationof the jack-head detached. Figfh i a partial section and (duration illustrating a. hold down for the jack.

1 is the jack-spindle, to which power may be applied for turning the jack, and as illustrating one form of utilizing the jack referonce is made to the parent case hereinnbovo referred to. This wok-spindlehas formed on or applied to it a base-plate 2, the outer end of which is adapted to travel on a camtrack 3 in accordance with the invention of the parent case, and this basc-plateis made or provided with a pair of parallel ears 4 at or near one end, and a pair of parallel lugs 5 about at its center, and a slot 6 beneath and hotwmm the lugs. Pivoted between the ears- 4 is a lever 7 having a depending longitudinally slotted segment 8 which WOlkS in the slot 1' and between the lugs 5 and is pinned vided upon opposite sides with the transvvrsognhlvs 14 and 15. and between these guides are the upright cheek-pieces 16 ad- :ugt hly-secured to the lever as by slots 17 and srro-ws or bolts 18. .On the inner end of the lover is the work-rost- 19, havin the end gage 20. Between the cheek-pieces is orrangn-d tho jack-lnanl 21, which is adjustably hold in lwtwrcn said check-pieces in any suitable way. as by the oblique slots 22 and bolts or arrows 13. In order to hold the jark'lnaul rigid and guide it in its adjustmentin the rlna-h-pirm's thr-se cheek-pieces may be provided with lhc oblique lugs 24: fitting in tho grmwvs 25 in the head. By this mennsthc jarlvhcad may be adjusted 'longitndinally and vertically with relation in the jack-head so as to insure the proper positioning of the clampingshocwith rela tion to the blank or work. The face of the rlampin -shoc may have any suitable means 32 for {:I'll'JPll'lQ' the hln ill; or work, serrations being shown as one such means. The upper portion of the plunger is slotted at 33 and in this slot the clamping-bar 34 is pivoted at or near one end, the other end of said bar being pivoted to a recoil device 35 arranged vertically in a. socket 36 in the rear end of the jack-head 21 said clamping bar thus floating between the parts it connects or to which it is pivoted and being bodily movable. This recoil device may be a plunger 37 supported in the socket by a coiled or other spring 38, and it has a limited upward movement in the socket. A clamping-lever 39' is pivotally mounted in the jack-head above the clamping-bar near its front, and has the cam end 40 adapted to act upon the clamping-bar to move it and its attached clamp the blank.

plunger 27 and by its eccentricity to lock these parts in clamping position, the recoil device serving to compensate for accidental variations in the height of the blanks for which the jack for the time being has been set, while sufiiciently strong to effectively Beneath the clampingbar' is a spring-plunger 41 arranged in the jack-head and constantly pressing upwardly against said her and serving to release the ill partswhen the clamping-lever 39 is relleaserll It will be seen by reference to Fig. "B -that the fulcrum of the clamping-lever 39 is in vertical alinement with the jack-spin dle and. Above itso as to get a direct and supported thrust.

Asriv ill be seen. the jack members are wril. supportedElntcrallv and vertically and thus rendered suliiciently rigid to meet the strains to which they are snlljec'rrd in use.

As shown in Fig. the jack-spindle may he hollow and contain a tension spring 42 reacting upon a rod 43 which is pivoted to the lower part of the jack-lever 7 and connected at its opposite and with an adjusting device 44 in the spindl so as to provide an adjustable downward tension for the jack, and. for convoniencr. this device is herein. referred to as a lmlrldkfifl.

'lhe jack and its spindle redesigned to ho bodily removable From the machine at pleasure.

The operation of the jack would seem to lobvious from the foregoing description. in n1. 1, the blank 45 is shown clamped in po ition, while in Fig. 3 the. full lines show (hiparts of the junk in open position For th H'm-pthm or renewal. of the worlr, \vhlle the lotlcd lines sbo the clamping mechanism in rlumping: position as in Fig. l.

lo the ma hine ol the parent cas'r. rel l' l'm'l to the jack is designed I have a rotary motion and also a vertical movement on the ram-trucks so as to present the work u amunpriate cuttiug mechanism and alsoso that it shall be properly presented to the operator for the introduction and the remoral of the blank.

it is to he understood that while the jack herein described was designed primarily for u e on a machine for making wooden heels for boots and shoes, the invention is app iculole to machines for manufacturing other articles, and also for nniking heels of other material, and the claims herein are to he understood accordingly.

What I claim is 1. The combination of a jack-lever having support said'liB lever, a clamping shop' carried by the jackat head and alined with the work-rest, a floating bodily-movable clamping-bar connected with said clamping-shoe at one end, a yielding support for said bar at that end, a. re-

3. The combination of a jack-lever having a work-rest, a jack head carried by said lover, a. clamping-shoe carried by the jackhead and alined with the work-rest, a. clampinghar connected Withsaid clampingshoe at one end, a recoil device connected with the other end of said bar, a clampinglever for actuating said bar, and a bar-lifting spring interposed between the jack-head and the clamping-bar.

4. The combination of a jack-lever having a work-rest, a jack-head carried by said lever, a clamping-shoe carried by the jackhead and alined with the Work-rest, i clamping-bar, a. plunger sliding vertically in the jaclehead and flexibly connecting ttu clamping-shoe and clamping-lever, means t yieldingly support the clamping-bar, an, a clampinglever for operating the bar an; its connected parts.
