Serial No. 491,818.

In the accompanying drawing, 1 represents the cement lining designed to properly cover the bottom of theturn table pit and the vertical walls thereof. Upon the bot tom of the pit is located the inner and fixed ring or track 2, which track is provided upon its upper surface wit-h a groove or trough adapted to receive and hold in proper relative position a series of anti-friction balls, 3, which balls are adapted to carry in part the weight of the rotatable portion of the turn table proper and for the purpose of providing means for causing the weight of the turn table to rest upon only a portion of the balls 8 the bottom of the run way or groove of the track 2 is formed with elevations, 4, and depressions, 5, which elevations and depressions, alternate in such manner, that when the balls are upon the elevations they will carry the weight of the turn table; but when the balls descend into the depressions they are relieved from the weight of the turn table and rolled down the incline, but are forced up the incline by the balls behind the lower ones coming in contact with the ball or balls moved by the rotation of the turn table.

Directly above the track 2 is located the turn table support proper, 6, which is cylindrical in form and of a diameter correspondl ing substantially with the diameter of the circular track 2, so that said turn table support will ride upon the balls 3 as illustrated in Fig. 1. 'F or the purpose of holding this turn table support in proper relationship with reference to the lower track 2 the fixed center post 7 is provided, which center post is secured to the hub 8, which hub is held by means of the spokes or connecting bars 9 and the center post extended into the hub 10 which hub is formed at the junction of the flanges or webs 11. The top or upper edge of the support (3 is provided with the shoulder 12, which shoulder is designed to support the center plate 13. T he turn table support 6 is provided with a series of notches or openings 14k, the number corresponding with the number of the trusses designed to be connected thereto. The inner ends of the trusses are each provided with the screw threaded bars 15, which bars are located through the openings 14 and upon which the nuts 16 are located. The trusses consist of the upper bars 17 and the lower bar 18, tied together by means of the lattice bars 19.

For the purpose of connecting the lower bars 18 at the inner ends to the support 6, said support is provided with a series of flanges 20, to which flanges the bottom or lower bars 18 are connected.

To the outer ends of the trusses proper are connected a series of segments 21, which segments when properly connected together constitute a ring rotatable with the turn table proper. Directly below this ring formed of the segmental sections 21 is located the fixed lower track or way 22, which is formed of a diameter corresponding substantially with the diameter of the con nected segments 21 or the ring made up of such segments. The track or way 22 is held in proper relationship with reference to the upper ring by means of the spoke-like connecting bars 23, said bars being detachably connected at their ends to the track 2 and to the ring 22 as illustrated in Fig. at. To the segmental sections 21 and preferably at their oints are located the connecting blocks 2%, which blocks are provided with the rollers or casters 25, which rollers or casters travel upon the top of the track 22.

It will be understood that in order to provide aturn table easily operated the weight of the turn table should be carried near its center or axis and hence the trusses should be so adjusted that they will carry the segmental sections 21 in such a position that the casters 25 will ride lightly upon the track 22. The main purpose and object of the track 22 and the ring made up of the segmental sections 21 is to prevent any excessive tilting of the turn table proper, or in other words to hold the turn table in proper horizontal position, regardless of the weight placed upon it. I

' It is well understood that in the use of turn tables the radial arms made up of the trusses, must necessarily be of considerable length and if any one or more of the trusses are sprung downward or out of their normal positions it becomes necessary to adjust said arms or trusses from time to time. In order to provide for this adjustment the screw threaded bars 15 are provided, by means of which the outer ends of the trusses can be raised up or let down independent of each other by means of the nut or nuts 16. It will be understood that when the nut or nut-s 16 are turned in one direction the tendency will be to pull upon the screw threaded bar 15, thereby lifting the outer end of the truss; and when the nut or nuts 16 are turned in the opposite direction the bar 15 will be released with reference to the support 16 or permitted to move endwise, thereby letting the lower end of the truss proper down.

It will be understood that the sector shaped plates 26 should be held against accidental displacement with reference to the center plate 13 and the structure proper and in order to provide against this displacement the bottom or undersides of each of the plates 26 are provided with the tangs 27 which tangs extend under the brace bars 28,

which bars are connected to the upper truss bars 17, said truss bars being preferably formed of angle iron. The plates 26 are also provided with the angle bars 29 to which are attached the bars 30. The outer ends of which bars are extended beyond the bars 29 so that when the plates 26 are moved endwise and brought home or into their proper positions the outward extending ends of the bars 30 will come under the horizontal flanges of the truss bars 17. The bars 30 and the tangs 27 prevent any upward movement of the plates 26 and for the purpose of holding the plates down and upon the flanges 31 formed upon the segmental bars 21 the screws 32 are provided and are seated and connected in the usual manner.

One of the objects of the invention is to provide a turn-table that can be easily set up or taken down and the parts so formed that a turn table of considerable size can be constructed and yet all of the parts being comparatively light can be handled with ease and with little labor. The turn table is what might be termed a lniock-down one and the parts can be shipped in a knockdown condition and assembled without the aid of a skilled mechanic. The turn table herein described being more especially designed for garages and upon which automobiles are to be placed; but the turn table here disclosed can be used for other purposes without departing from the nature of my invention.

It is of importance that the turn table pit should be properly drained sov that no water will stand in the pit and in order to providefor this the bottom of the pit is provided with a series of what might be termed trenches 33, which trenches 33 lead to the basin 34, from which basin leads the drain pipe 35.

It will be understood that in order to easily detach the bars or rods 23 the sockets 36 should be open ones so that the inner ends can be lifted up and the bars 23 pu rled from the sockets 37 formed in the segmental bars 21.

For the purpose of preventing the cement from breaking or crumbling away at the top of the pit, a metal band or inner hoop 38, should be provided, which band is provided with a series of tangs 39, which tangs are embedded in the cement as illustrated in Fig. 1. It will also he understood that in order to provide easy means for lifting the center plate 13 up and detaching it from the support 6 it should be provided with the handles 40, which handles should be located diametrially opposite each other and so formed that when they are not in use they will assume the position shown in Fig. 3 and for the purpose of reaching or getting under the handles and lifting them upward for a limited distance the center plate 13 is provided with the depressions 4:1. The handles l0 should be provided at their lower ends with the nuts or heads e2, which come in contact with the bottom or under-side of the center plate 13.

The ring 22 should be formed in sections and the sections connected together by means of suitable clamping bolts 43. For the purpose of preventing water from accumulating between the vertical walls of the pit and the ring 22 the lower edge of the ring is pro vided with recesses 44 through which recesses the water can pass and find its way to the drain pipe 35.

For the purpose of providing means for easy access to the parts of the turn table located adjacent the support 6, said support is provided with a series of openings, 45, said openings being located between the webs 11 as best illustrated in Fig. t. By providing the openings 45 less metal is required, thereby, producing a structure that will be light and easily transported.
