braces aV gimbal ring 7 6 and is pivotally connected with the ring by means of bearing rpins 7 8 secured in the ring and engaging in bearings in the arms oit the yoke.V rlhe ring 7G embraces a yoke 8O mounted on the upper end of a stud 82 passing through and se' cured in the sleeve 9 and isr pivot-ally connected with the latter yoke by means ot' bearing pins 84 secured in the ring and engaging in bearings in the arms of the yoke. The shaft 7 2 through its connection with the sleeve 9 is held from rotary movement withl the j ack spindle but is tree to swing in any direction relative to the stud in accordance with the swinging movements ot the-spindle. lhen the shoe is placed on the jack the toggle lever 52H54 is straightened and the toggle actuating and controlling lever 62 and the intermediate lever 56 ar-e held in position through the engagement ot' the gear segment 68 withthe bevel gearl 7() to maintain the heel support carrying arm 14 in a position remote from the toe rest supporting arin 11as shown in Fig. 5 against the tension ot the spring 17. Upon the placing Vot'a shoe on the ack the toggle lever l52--54 is broken allowing the spring 17 to actuate the arm 14 to adjust the shoe in a predetermined position longitudinally ot the jack and to clamp the same in position as shown in Fig. 4. r151s the jack is turned through substantially hallz a revolution in the direction ofthe arrow ct, Fig. 4, during the. op-

controlling lever 62 is swung on the stud 58 in the direction et the arrow vappli-ed thereto in said ligure and the intermediate lever G is swung therewith until at the completion of the operation on the shoe the toggle lever is straightened. 'As the. jack is turned in the opposite direction or inthe direction of the arrow Fig. 5, throughsubstantially halt a revolution after .the completion ot the voperation on the shoe to bring thejack toits initial or starting position, the'lever 62 is swung von the studV 58 in the direction of the rlhe toggle lever 52-54 is then in aA straightened condition and is moved longitudinally from the lever V62 through vthe lever 56 to swing the arm 14 away from the arm 11 into the position shown in said ligure. T ie shoe is thus unclamped from the jack and may be removed from the jack merely by liftingthe shoe from the last pin 1. Y

To take up lost motion and assist in straightening the toggle lever at the completion ot' the turningA movement of thevjack produced during the operation oit the niachineron the shoea coiled'spring 86 is at=- ltached at one endr to thearm14a1idat its other `endto a projection formed on thel from such vadditional member 52 ot the toggle lever. This spring ensures the straightening-ot the toggle lever. The yielding connection between the interimedia-te lever 56 and the toggle actuating and controlling lever 62 will take care of any additional movement or overthrow of the lever 62 at the completion of the opera-- tion on the shoe after the toggle lever is straightened.l During such additional movement ot the lever 62 the lever 56 isheld stationary by the toggle lever and the lever 62 moves independently of the lever 56. Fig. 15 shows the conditionof the parts resulting movement of the lever 62.

During the sewing of the seam along the shank of the shoe on thefside of the shoe first sewn the jack is turned to a certain degree in the direction ot the arrow Fig. 5. lf the voperator should start the machine whilel the toggle lever is straightened the movement ofthe lever 62 in' the direction ot the arrow, Fig. 5, which would be produced by this rotary movement of the jack would be liable to result in breakage of certain et the part-s. In order to break the toggle lever when this rota-ry movement of the jack occurs incase the machine is started with the togglelever straightened7 a chain 88 is attached at one end to the projection on the member 52 of the toggle lever and at'its other end to the lever 56.

ln order to disengage the pawl 38 from the ratchet wheell 36 and to resetv the ypawl in position to be engaged and held-by the latch 41, the rack bar 28 is formed with a project-ion 90 at its outer end arrangedto engage a laterally projecting arm 92 formed on the pawl. As the heel support carrying arm 14'is swung from the position'shown in Fig. 4 to the position shown inFig. 5, and the bar 28 is thusmoved longitudinally to the left to the` position shown in the latter ligure, the projection 90 on the bar engages the arm 92`on the pawl and.V moves the pawl to the position shown in Figs. 5 and 9. The pawl is held in the position shown Vin Figs. 5 Vand 9 until the arm 14 is released land starts to swing ltoward the toe rest supporting arm 11 under the influence ofthe coiled spring 17 when thev projection 90 Yon the bar 28 is disengaged from the arm 92 on the pawl by the longitudinal movement of the bar to the right;v rlhe paw'l'is then lcaught by the latchand held until the Ylatch is disengaged roni-the pawlby the movement of the teeler lever 48 produced by theengage ment of the v.shoe therewith.
