Specification of Letters Patent.

Patented July 24L, 1917.

Application filed January 18, 1917. Serial No. 143,111.

To all whom it may concern:

Be it known that I, PAUL HELD, a citizen of the United States, residing at St. Cloud, in the county of Benton and State of Minnesota, have invented a new and useful Merry- Go-Round, of which the following is a speci flcation.

The device forming the subject matter of this application is a roundabout or merrygo-round, and the invention aims to improve the construction of the rotatable member of the roundabout, and to provide novel means whereby the said rotatable member is supported.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description. proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in side elevation, a round about constructed in accordance with the present invention, parts being broken away;

Fig. 2 is a top plan of the roundabout;

Fig. 3 is a side elevation showing the upper portion of the roundabout, parts being sectioned to disclose the anti-frictional mounting for the rotatable member;

Fig. 4 is a side elevation of the plug which is inserted into the main supporting post;

Fig. 5 is a fragmental side elevation showing the upper end of the main post; and

Fig. 6 is a transverse section taken through the main post.

In carrying out the present invention there is provided a main post 1 which may be a piece of pipe, set in a suitable foundation 2 of concrete. In the upper end of the post 1 there is formed a notch 3, as shown in Fig. 5. The numeral d denotes a plug inserted in the upper end of the post 1 and provided with an outstanding bearing head 5 equipped in its upper end with a concaved seat 6. The head 5 is supplied with a depending lug 7 received in the notch 3 of the post 1, so that the bearing 4=5 cannot rotate in the post.

Surrounding the post 1 at its upper end and journaled for rotation thereon is a cap 8 having a substantial top 9 provided on its under side with a concaved seat or recess 10. An anti-friction ball 11 is received in the seats 6 and 10. The top 9 of the cap 8 is provided with an upstanding nipple 12 having an oil bore 14- diseharging into the seat 10 on the ball 11. The nipple 12 is provided with opposed outstanding ribs 15. A top plate 70 rests on the part 9 of the cap 8, and the nipple 12 passes through the top plate. The top plate 70 is provided with radial openings 16 which receive the ribs 15. In this way, the cap 8 and the top plate 70 are connected for simultaneous rotation, it being obvious, when the nature of the device is better understood, that if the top plate 70 could rotate on the part 9 of the cap 8, some of the advantage derived from the anti-trictional support afforded by the ball 11 would be lost.

The numeral 17 denotes brackets preferably in the form of angle members, each angle member or bracket 17 including a lateral flange 18 and an outstanding flange 19, the lateral flanges 18 of the brackets being at tached to the cap 8 by securing elements 20. The numeral 21 denotes inclined supports in the form of rods, having angular ends 22 passing through the flanges 19 of the angle brackets 17 and connected therewith by means of nuts 23. The lower ends of the inclined supports 21 pass through lower bars 24, and are attached thereto by means of nuts 25. Seats 26 are attached as shown at 27 to the outer ends of the lower bars 24. The numeral 71 denotes a bottom plate having an opening 28 receiving the post 1 loosely, so that the plate 71 can rotate on the post. The inner ends of the lower bars 24 are connected by securing elements 29 to the bottom plate 71.

The invention comprises upright hangers 72 having angular ends 30 passing through the flanges 19 of the brackets 17 and held thereto by nuts 31. The lower ends of the hangers 72 pass through the bottom plate 71 and are attached thereto by nuts 33, so as to support the bottom plate. The bottom bars 24 are connected by braces 84% which may be used as additional seats, the braces or seats being secured to the bottom bars 24 as shown at 35.

Radial top braces 36 are provided, the inner ends of the top braces 36 being attached to the flanges 19 of the brackets 17 by means of the ends 22 of the inclined parts 21, and

the nuts 23 thereon. Top bars 37conneot the" vided, the same-being supplied at their lower ends with eyes 4-1 receiving the extensions 39 of the top braces 36. Nuts 45 are threaded onto the extensions 39 and hold the eyes 44 and 40 thereon. The upper ends of the guys 43 are provided with hooks 47 received in openings in the top plate 70.

From the foregoing it will be observed that there is disclosed in this application, a simple but strong roundabout, the rotatable member of which is well adapted to 'withstand severe usage.

When the rotatable member is turned, the top' 9 of the cap 8 rotates on the anti-friction ball 11, and as a consequence, the rotatable member will turn readily. The bearing shown in Fig. 3 may be lubricated by inserting oil through the oil duct 14.

Having thus described the invention, what is claimed is 1. 'A roundabout comprising a post; a cap journaled on the upper end of the post; a bottom plate journaled on the post; hangers connecting the cap and the bottom plate and located adjacent the post; lower bars having their inner ends secured to the bottom plate; seats carried by the outer ends of the bottom bars; inclined supports connected at their upper ends with the cap, and connected at their lower ends to the bottom bars intermediate the ends of the bottom bars; top braces projecting outwardly from the cap;outer hangers connecting the outer ends of the top braces with the outer ends of the bottom bars; upwardly inclined guys connected at their outer ends with the up per bars; means for connecting the inner ends of the guys with the cap; and a frame joining the top braces.

2. A roundabout comprising a post; a cap journaled on the upper end of the post; a bottom plate journaled on the post; hangers connecting the cap and the bottom plate and located adjacent the post; lower bars having their inner ends secured to the bottom plate; seats carried by the outer ends of the lower bars; a rectangular seat-forming frame connecting the lower bars; top braces projecting outwardly from the cap; hangers connecting the outer ends of the top braces with'the outer ends of the lower bars; a

frame connecting the top braces; and down wardly inclined guys connecting the cap with the top braces.

3. A roundabout comprising a post; a bearing carried by the upper end of the post; a cap inverted over the upper end of the post, the cap and the bearing having seats disposed coaxially with the post; a single anti-friction ball interposed between the bearing and the'cap and received in the seats the cap having anoil duct leading to the seat thereof; a rotatable passenger carrier plate and the nipple for-simultaneous rota 'tlon' a rotatable seat-carr 1n structure 7 y b 7 and means for connecting the seat-carrying structure with the top plate.

5.. A roundabout comprising a post; a cap inverted over the top of the post and rotatable thereon; a bracketcarried by the cap;

a lower bar; a seat carried by thelower bar; a support connected at its lower end with the lower bar and having its upper end mounted in the bracket; a top brace having its inner end mounted on the upper end of the support; an outer hanger connecting the outer end of the top brace with the outer end of the lower bar; and a guy connecting the outer end of the top brace'with the cap.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature 111 the presence of two witnesses.

PAUL HELD.
