The jacks are thus adjustable'back and forth'to'proper'position for engaging the frame or chassis of an automobile. The jack screws '83 are operated. by little'hand wheels 84. The heads 85 are provided'with screw clips 86 for coupling to the chassis or frame,

- as clearly detailed in Fig.8. 'VVhilei sliding the adjustable ,stand under an automobile,

The inner ends of the levers 6 are actuated by means of the screw. 9 provided with a flanged actuating nut 91 .which engages reunded projections62 on the inner ends of the levers As the screw 9 is actuated, the nut 91 is pulled'down" to the position indicated by; 1 dotted lines in Fig. 2, or toy any intermediate position. fThe screw 9' is actuated by the worm gear 92 which is secured'to flange '93 1at thebottorn of the screw. The worm lgeariprovided with ball bearing 94 on athe underside of the'turntable 4, so that the screw'is very readily rotated centrally of the said table. The turntable is driven by means 4 tion gear train'113.

of the worm 10 on the driving shaft 101 which is actuated by a reversible electric motor 11v through belt drive 111, shaft 112 and reducfIt will-thus besee'n that the screw 9 can be operated in either direction from the, re versible motor;11'- and whenit is pulled down.

to j the position indicated by dotted lines in Fig. '2, the elevating frame is raisedto its highest position. Of course, to do this the turntable 4 must be held against rotation and this isjdone by the yoke;1 2 pivoted at 121 which is swung up into engagement with one of the levers 6. lVhenthe lever 6 swings up out of engageinen t ,with the yoke 12, theturntable .is freeto revolve and the turntable. would be free to revolve at any point dur ng itsje'lev'ation by throwing the yoke down to I the position indicated dotted lines; in

. The friction ofthe parts -on .the screw would, when the turntable is released, perject'to, accidental displacement. We, therefore, provide means ,for locking the screw to theturntable, after the properelevationhas been attained. To do this we provide a clutch.

13 madeup of two collapsible members131 and 132 which are semi circular in form. These engage cooperating recess 46. These clutch "members are keyed to the screw by l-z eys 133 and are held in collapsed disen-' gaged position by the encircling spring 134 in the groove 135. There are disposed between these semi-circular sections, wedge pin members 136with outward taperingends; 137, flattenedat the sides, and withbeveled rocates in the bore 95 and a ball bearing 143is interposed between the head and the cone. Thelower end of the plunger 141 is provided with an actuating knob 144 and the" plunger 141 reciprocates centrally through through the ball retainer of ball bearing 145. The lower end of the plunger 141 issquared and is straddled by the'bifurcated cam 146 which is controlled by the rod 147 havingknob' 148-.= .11

When" it is desire'd to lock the elevating screw to theturntable-and suppress its operatio n, thefknob '148is pushed in and thebi- 1 furcated' cam l46ywedges and cams against *the knob 144, pulling the actuating cone 14 down against the inner beveled ends 138 of the actuating ins 136. This forces the same outwardly so t at they wedge the clutch members 131, 132 apart into engagement with the recess 46 in'the top of the turntable 4, thereby locking the screw to the turntable so that actuation of the worm gear 32 from then on slowly turns the turntable and all that is supported thereby in either direction, depending on-the adjustment'of-the reversible motor.

The screw, being thus locked to the turntable, can no longer raise or lower it. y

Of, course, in lace of a reversible motor,

it wouldbe possi 1e. to make use of a reverse gearJThis is a detail, however, whichwe have not deemed it necessary to illustrate.

a In ,theoperation of our improved display stand, an automobile is located at the desired point for display. The body springs of the automobile are lockedby a suitable clamp or by wiring so thatthe will not open out when the loadis released y'the' elevating means.

'We then slide our improved display stand centrall under'the body which is readily accomplis ed because'the same is carried on the.

three rollers, one of which turns and guides Which are flattened top and the others by the transporting handle. The I K adjusting jacks are; closed downwithinthe mitthe same to revolvebutit would be subframe While thisldclating isbeing done- I When the stand is in place, the turntable rotated until theadjustin-g jacks 8 'swi'ngto I the'proper position. 'They are adjustable along the elongated pivots provided to acment with'one of the levers 6. The electric motoris operated with the structure adjusted in position, as indicated in Fig. This drives the bottom position.

This action may becontinued until the arms 6 are lifted out of the yokes 112, which occurs at the time that the nut is brought down to The table thus in itscompletely elevated position, the screw-having reachedthe end By reversing the gear, thetable can be'roagain. The attendant should watch'thisoperation and stop the 'JI IIOtOI EIlL the required time. v e P 1 Then the display stand iseompletely ele-- vated, the screw and the turntable may, itt

The

screw is released from thetu'rntable by pulli 1 tions' just described.

a By'thus providingmeans for locking the screw to the turntable,'it may-beloeked there-h to at any point; inits elevation, thus'making it possibleto lift,an-automobileonly slightly above the floor," which is, the preferred'position for automobile display purposes,fland vthen lockingv thescrewo i r I It is an object of this maohine' jto gradually turn and present all sides of the automobile w for inspection so. that aperson desiringto inspect the automobile," stopping at a display window, can observe'all sides and allparts e in a few minutes bysimply standingandob-' serving the structure.
