is disposed adjacent the lower arm di' the lever and is adapted to hold thc nose 17 ot the lever out of engagement with the rack when the parts are in the position shown in Fig. l.

Likewise vertically disposed within the space beneath the platlorm 11-12 is the Seat standard 21 carrying upon its upper end the chair seat 22. The vstandard 21 is provided along its rear ace with a toothed rack 23 and at its lower` end is rigidly crossconnected by means of the yoke 2a with the lower end of the foot rest standard 13,. j

As thus far described it will be observed that the chair seat 22 and the toot rest l5 occupy positions, the former immediately above the raised portion 12 of the platform and the foot rest immediately above the floor level of the platform at 11. And it is this condition of adairs which the customer encounters upon entering the shoe shining shop. Standing upon the platform 11 the foot rest l5 is substantially flush with the floor and, seating himself in the chair scat 22 his Jfeet readily aie'accoinmodated on the foot rest 15. Villien seated in the chair, the foot rest 15 may be adjusted vertically to suit the length of limb of the customer by 'the workman grasping the oot rest and litting the same, the nose 17 of the lever riding over the ratchet teeth and engaging the same when the foot rest l5 is released.

The provision made Jfor raising and lov ring the seat 22, the toot rest 15 and the ustoiner bodily will now loe explained:

A motor is indicated at y25 from which a drive belt 26 leads to the pulley 27 on the driven shaft 28. This shaft carries a sprocket 29 and a belt pulley 30. The sprocket 29 is connected by the sprocket chain31with a companion sprocket 32 loosely mounted on the countershait 33 while the belt pulley 30 is connected by a cross belt 34 with a belt pulley 357 also loosely mountrilhe adjacent faces of the hubs of the sprocket 32 and the belt pulley 35 are concaved. for coaction with the double :tace Jiriction clutch 36 37.

keyed to the countershait 33 and shi'ftable longitudinally thereon by means ol the clutch actuating lever 33 ulcrumed at 39 and connected by a link e() with a clutch control lever 4:1, the handle l2 of which projects through the wall 43 of the structure.

Upon the countershaft 33 is mounted a pinion L14: in mesh with a larger pinionf fixed upon a transmission shaft 4G which carries another small pinion 47 which is in' mesh with the 'larger pinion 43 on the second transmission shaft 4:9,v which latter shaft also carries a pinio-n 50 arranged in mesh with the rack 23 on the standard 21.

lt should non7 be obvious that iiL1 the clutch control lever be moved to the right the clutch 37' will be brought into frictioiial engagement with and effect a driving of the countershait by means of the sprocket,l

32, thereby vitalizing the train of: gearing and causing the seat standard 421 with the seat 22 to move upward, carrying with it` through the cross connection 24 the foot rest standard 13 and the foot rest 15, A shifting ot the clutch control lever l2 to the left will, on the contrary, move the clutch member 36 into engagement with the pulley 35 and cause the driving of the shaft33 in the opposite direction and9 through the train,l will cause the lowering of the seat standard 21 andthe seat 22, carrying with them at y the saine time the ioot rest standard 13 and the foot rest 15. ln order to automatically stop the raising and lowering mechanism as the seat reaches its upper and lower extreme positions, means are provided as follows: Un the side of the seat standard 21 at 51 is arranged a cam which as the seat standard descends' inipinges against clutch actuating lever 38, as indicated in lig. 9, and shiits the same to neutra-l position. ,Tin order to stop the mechanism when the seat and 'foot rest reach their extreme lower positioin a stop rod 52 is slidably mounted within the bracket and is upwardly pressed by means of the spring 54e. rllie -A lower end of the stop rod 52 is angularly bent as indicated at 55 and extendsl beneath and in alineinent with the standard 2l. vrl`he upper end or' the stop rod 52 carries a wedge like cam 56, the inclined :tace oi which is adapted to bear against the opposite sidejoi the clutch actuating lever 33 when the descending standard '2l shall have engaged the angular portion o5 of the stop rod and push the same downwardly against the tension o l the spring 5ft. y

ln' order to positively support theseaty standard 21 in elevated position, said seat standard is provided'with a ratchet toothed plate 57. adjacent the cain 51, the teeth of which ratchet are adapted to be engaged by the teeth ot a spring detent 53 slidably mounted in the block 59 and held against the standard 21 by the yieldiii spring 60. isprovidcd with a'slot 31 within which engages a pin 62 carried bv the clutch control lever 41. lt will thus be seen that upon the actuation of the clutch control lever l1 to the left to effect the lowering of the elevated seat, the detent 58 will be first Adrawn out of engagement with the ratchet teeth 27 betorethe clutch becomes effective,

thais releasing the positive engaging means and permitting the seat and its standard to descend under the control of the pulley t35. The actuation of the clutch control lever l1 in the opposite direction to eliect the raising oi the standard will not, however, by reason of the slot and pin connection, affect in any4 way the spring detent.

A forcent the l'llie outer end oit' the detent 53 1 izziA 'A seat approaches its estreme upper position and likewise when. it reaches its extreme lower position.
