Patented Apr. 28, 1931 UNITED STATES SYLVESTER E. MOORE, OF YUMA, ARIZONA TURNTABLE Application filed February 12, 1930. Serial No. 427,888.

My invention has reference to turn-tables, and it is a purpose of my invention to provide a turn-table primarily designed, although not necessarily, for use in connection with the automobile driveways of private residences and'preferably adjacent the garage, in order that an automobile may be driven onto the turn-table and the latter then manually rotated to reverse the position of the automobile so that it can be driven from the driveway front end foremost, and not backed out as is the present method. In this manner I eliminate, or at least reduce to a minimum the possibility of personal injury to predestrains traversing a pavement at the end of the driveway, or any accident as a result of the drivers failure to observe the boundaries of the driveway as well as the trafiic traversing the street intersecting the driveway.

structurally my invention is characterized by its simplicity, low cost of manufacture, easy mode'of assembly and disassembly, ready substitution of any of its parts should they become worn or broken and primarily a turntable in which the platform thereof is so freelly supported for rotation that when an automobile is thereon, it can be easily rotated by a single person and without the necessity .of employing mechanical power.

I will describe only one form of turn-table embodying my invention, and will then point out the novel features thereof in claims.

a In the accompanying drawings:

Fig. 1 is a view showing in top planone form of turn-table embodying my invention with a portion of the platform thereof broken away. to reveal the construction of'the platform frame. Y Fig. 2 is a vertical sectional view taken on the line 22 of Fig. 1. .7 Fig. 3 is an enlarged vertical sectional view taken on the line 33 of Fig. 1. 1

'Fig. L is a detail view on a reduced scale showing the platform in bottom plan.

' Fig. 5 is a view on a reduced scale show-' ing in plan the turn-table embodying my invention in applied position within the driveway of a private garage.

In carrying out my invention, adriveway D leading to a garage G is constructed with a pocket P of such diameter as to receive the parts of the turn-table embodying my invention, and in such manner that the turntable is fluish with the surface of the driveway to permit the automobile to be driven onto or off of the turn-table incident to enteringor leaving the garage. Centrally within the pocket P is a pier 15 formed of concrete or the like and havingjembedded therein a post 16, the latter having at its lowerenda disk shaped head 17 which, when embedded in the concrete serves to hold the post in true vertical position. The upper end of the post projects above thepier' 15 so that it may be utilized to form an axis upon and about which the platform of the turn-table is supported for rotation. As best illustrated in Fig. 2, the platform of the turn-table is made up of a frame F for supporting a top T. The top T;may be ofany suitable construction but in the pres ent instance it is formed ofwooden boards secured to each other at the marginal edge of the top by means of straps'18 of iron or any other suitable metal, as best illustrated in Fig. 4. Other straps 18 are employed 'to secure tlieboards to each other at points spaced from the marginal edges. The frame F comprises a plurality of subsidiary frames which serve 'to-efiectively support the toplT and in such manner that'the weight'of an automobile when'on the top will be distributed uniformly over the entire area ofthe platform in order that the platform'may be easily and manually rotated. f

The frame is'con'structed with the purpose -in mind of permitting reading substitution ofits parts in'the case of repair, and

the frame'is made up of a plurality ofsub sidiary frames detachably secured -to.- each other so that in the eventof repair, any one frame may be detached from the other and a new frame substituted; These two subsidiary frames, designatedat 19, are made from lengths of steel straps bent in the form of a U, with their intermediate portions in confronting relation'to each other, and their parallel portions projecting to the marginal edge of the topT. The other two subsidiary parts which can be easily made." To this end 7 frames, designated at 20, are likewise made of straps of steel or other suitable material, and constructed so as to form linear portions 20* arranged in confronting relation to each other and divergent end portions 20 which extend to the marginal edges of the top T. The linear portions 20 are inter posed between the medial portions of the subsidiary frames 19, and they are secured in this relation by means of two pairs of U bolts 21 extending through plates 22- with nuts 23 on the ends of the bolts for securing the plates to the bolts and the bolts in encompassing relation to the adjacent parts of the subsidiary frames. Between the two pairsof U bolts 21 are arranged two plates 24 and 25 held in superimposed relation to each other at the lower side of the frames by means of two U bolts 26. Although I have shown and described only two subsidiary frames 20, it will be understood that any number of such frames may be employed depending upon the load to be supported on the platform. For example, two subsidiary frames may be suflicient for an automobile of light weight, whereas, for heavy automobiles, four or more of such frames are employed.

As best shown in Fig. 2, the lower plate 25 is provided with an opening, the walls of which are outstruck to provide a collar 27, and the internal diameter of this collar is such that it receives the upper end of the post 16 and in such manner that it bears against the under side of the upper plate 24. Thus, a bearing is provided for the post, with the collar 27 maintaining the platform frame against edgewise displacement in respect to the post.

Lubrication and reduction of friction between the frame plate and post may be accomplished by the provision of a tube 28 eX- tended downwardly through the plates 24 so that its lower end is disposed between the plates 24 and 25 and adjacent the post 16 so that a suitable lubricant may be supplied through the tube and into the bearing.

The radiating arms of the subsidiary frames carry at their outer ends brackets29 in which casters or rollers 30 are journaled, these rollers adapted to have rolling contact with atrack. This trackis disposed within the pocket P and upon a suitable concrete base. The track is made up of one or more angle bars 31 arranged in circular form to provide a circular track having the diameter of that defined by the arrangement of the rollers 30. The track may be partly embedded in the concrete base in the manner illustrated in Fig. 2, and so that the vertical webs of the angle bars which constitute the track properare effectively braced against horizontal movement or bending. Upon the upper edge of the vertical part of the track, the

rollers 30 are adapted to ride and to support the platform against any lateral movement in the event that the load imposed thereupon is not evenly distributed over the platform.

In practice, the platform of the turn-table is freely rotatable upon the post, and with the turn-table positioned in the driveway and in respect to the garage, as illustrated in Fig. 5, it will be clear that an automobile entering or leaving the garage can pass onto the platform, so that by rotating the latter, the automobile may be positioned with its front end foremost so that it can be driven in this position out of the driveway.

Although I have herein shown and described only one form of turn-table embodying my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.

I claim:
