uurrsn STATES WILLIAM HAINKE, or KENSINGTON, KANSAS.

ROUNDAIBOTIT.

Application. filed June 12,

'llhis invention relates to new and useful improvements inv roundabouts and aims to provide a novel, simple, and rigid roundabout eonstrluztion wherein a large number of children may dispose themselves thereon, and wherein the device may be rotated by the children at any desired speed. Further, the construction is such as to reduce possibility of accidents to the children to a minimum, as woli. as to reduce to a negligible degree the striking of the children by the various parts of the device should they fall from the roundabout either inwardly or outwardly thereof.

A further and important object is to provide a simple but efficient bearing structure between the roundabout frame and its supporting polo so as to permit the device to be easily rotated. Furthermore, this character of bearing will prevent sagging of the frame structure, even in the event a large number of children disposethemselves upon one side of the roundabout only.

lVith the foregoing and other objects in vi ew as the nature of the invention will be better understood, the same consists in the novel form, wmbination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

in the drawings wherein like reference characters indicate corresponding parts throughout the several views:

Figure 1 is a top plan view of my improved rol md about.

Figure 2 is a side elevation thereof.

Figure 3 is al :lragmentary sectional view of the bearing unit between the frame and its supporting post.

Figure 4-. is a fragmentary horizontal section taken substantially upon the line 4-4 of Figure 2 looking downwardly in the direction of the arrow, and

Figure 5 is a fragmentary vertical section through the device.

Now having particular reference to the drawing, my novel roundabout structure consists of a supporting standard 5 in the form of a hollow pipe of predetermined length, and anchored at its lower end within a su1table base 6, set within the ground as disclosed in Figure 2. Frictionally arranged Wltll11l the upper end of this pipe standard 5 1s a cylindrical bearing cup Z, Figure 3, having a. flange 8 at its upper end to rest on the upper end of the pipe standard. Located perpendicularly within this bearing cup 7 1s a short shaft 9 between the lower end of which and 1528. Serial No. 284,794.

frame bar attaching plate 12, upon the center of which is arranged an ornamental knob 13 having a transverse opening at its lower end so as to facilitate the engagement of a nut 14- upon the reduced threaded end of the shaft 9 for securing said plate 12 thereto. Bolted to the plate 12 as at 15 are the inwardly bent upper ends of downwardly and outwardly extending roundabout frame bars 16 having predetermined spaced relation and being preferably constructed of piping. The lower ends of these frame bars 16 terminate in predetermined spaced relation with the ground surface, said. lower ends thereof being bent horizontally outwardly, and being arranged between adjacent ends of seat boards 17 combining to provide a circular seating platform as clearly illustrated in Figure 1.

The adjacent ends of these seat boards 17 are interconnected at their under sides by attachin plates 18, the lower outwardly bent ends of the frame bars 16 being also bolted to said plates 18 as disclosed. Arranged entirely around the frame bars 16 at a suitable distance above the seat platform and secured thereto by welding, bolting or the like is a hand rail .19, preferably of hollow or pipe construction. Adjacent each of the frame bars 16 said hand rail 19 is equipped with suitable hand knobs 20. Suitably attached at their outer ends to this hand rail 1.9 and adjacent said frame bars 16 are horizontal inwardly extending frame bars 21, the innor ends thereof being associated with a com mon SllpPOllilIlg member 22 having a cen tral opening through which the standard 5 extends, said member adapted for free rotation upon said standard and being supported against downward movement by a collar 23 arranged upon said standard, see Figure Associated with the horizontal frame bars 21 and at the inner ends thereof is a circular seat board 2&- having an enlarged central opening 25 therein, said seat board being secured to the horizontal frame bars 21. through the medium of U-bolts or the like 26.

This inner seat board 24 is an optional feature and may be removed from the roundabout if its use is not desired.

In view of the foregoing description when considered in conjunction with the accompanying drawings, it will be apparent that I have provided a novel simple, and durable roundabout structure that is well adapted for all the purposes heretofore designated, and

even though I have herein shown and described the invention as consisting of certain detail structural elements it is nevertheless to be understood that some changes may be made therein without afiecting the spirit and scope of the appended claim.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is In a roundabout construction, a vertical fixed standard, rotary means arranged in and extending above the standard, a series of spaced bar, members arranged adjacent to each other at their upper and inner ends and connected at said ends with said rotary means and extending radially and downwardly therefrom, seat sections carried by said bar members at the outer ends thereof, supporting means on the standard at an inter1nediate point in the height thereof, rotary means surrounding the standard and superimposed on said supporting means, a rail surrounding and supported 011 the said bar members, frame bars interposed between and connected with the last named rotary means and said rail and spaced apart, and seat means surrounding the standard and superi1n1 )osed on and connected to said bars; said seat means being arranged in a horizontal plane above that of the first named seat sections.

In testimony whereof I allix my signature.

WILLIAM I'IAINKE.
