RQUNDABOUJIli- Application filed lune 15, 192,6- Serial No. 116,208. I

i The. present} invention-- relates to improvc-- mentainamusement devices and has. for. a

principal. object to provide a. roundabout I which will-afford amusementto grown, folks s as well as to children.

Unsolithe important objects of the p resent invention is. top-rovide. a roundabout"which includes a vertically arranged spiralstem, the, 'convolutions of; which-are disposed in m such. relationwith-respect togo'ne: anotherwas to provide atrack, a. cross. member sing adapted to. travel downwardly on, thettacl; formed by the; convolutionsz by gravitation net atthe same. timeirotating at; a relatively l great.rateof-a'speed.

A'ituntherobject of the invention is to provide a. vertical pin in association; with the cross bar, which: pin. is adapted. toxtnavel downwardly within the convolutions of the 2 .1 spiralstemi and which. pin; provides a guide for balancing ,the cross bar during its downward movement on the stem.

A further object of the invention is to provide a roundabout of the above mentioned character wherein a cable or string may be attached tothe upper end of the vertical pin to facilitate the movement of the cross bar I in an upward direction on the stem.

A further object is to provide a roundabout of the above mentioned character which is simple in construction, inexpensive strong and durable and further well adapted to the purpose for which it is designed. 7

Other objects and advantages of the in vention will become apparent during the course of the following description taken in connection with the accompanying drawing. In the accompanying drawing forming a part of this applicatiomand in which like numerals designate like parts: v

liigure 1 is a side elevation of the roundabnut, and

Figure 2 is a fragmentary detail perspec tire viewof the vertical pin and the right angularly disposed cross member forming a part of the roundabout.

In the drawing. the numeral 1 designates a base and extending upwardly therefrom is the spiral stem designated genorally by the numeral 2. This stem is formed of a single strand of wire, and the convolutions 3 are spaced from each other to provide a spiral track the purpose of which will. be hereinafter more fully described.

Arranged; on opposite sides. of the stem 2 are, the supports 4t and. 5. respectively,- the same be ng provided with.usu-alibraces il-lus-.

huddl -di it 'lhe-horizontal; brace? extends between the upper ends o ii' the vertical sup: ports 4 and:5,and suitable trusses 8 of any well? known constisuctiona are. associated with: the horizontal brace member: 7; in themanner clearly shown in Figural.

The roundabout further rnclud'es'a pain oft intersecting cross; members il and 10 reaped ti velythe intermediate portion of the cross member. 10 being arched as; illustratedat .11. A vertical pm 12 has'itsintermediate/portion scoured; to, thewinterse'cting portions of the cross members 9 and 10. and: suitable braces 13 are associated: with the interme. d te portions or the cross members; in. the

of the cross members -.9 and 10. A seat 15 is arranged on the outer end of each of the cross members and a suitable handlebar 16 extends upwardly from each of the cros."

members adjacent the respective seats, is

clearly shown in Figure 1.

The vertical pin 12 is adapted toltr'avel vertically within the convolutions of the spiral st-em 2Qand furthermore acts as a guide i or balancing means for thecross members 9 and 10. The intermediate portions of the cross members are adapted to travel on the track formed by the convolutions 3 and the manner in which the roundabout rotates and travels downwardly will be presently apparent.

Acablel'? is attached to the upper one of the vertical pin 12, and this cable extends upwardly through the 'convolutions of the spiral stem 2 and is trained over suitable.

guide pulleys 18and 19 which are mounted 'on the intermediate portion of the horizon- A ring 14: extends around the outer e-nds till raising the seat supporting cross members i to an elevated position.

The operation of theroundabout may be briefly described as follows. With the parts arranged as shown in Figure 1, the children climb up the ladder 21 and the cross members 9 and 10 are in turn rotated by band tion will afford amusement to Weight 20 is, elevated.

has descended to such a point as to; permit until all the'seats are occupied. As soon as all of the seats are occupied, the Weight of the occupants Will, automatically cause the cross members 9 and 10 to travel down- Wardly by gravitation on the stem 2 and at the same time rotate and during the down Ward movement of this roundabout, the When the roundabout the children to reach the ground and leave the seats 15, the Weight 20 Will automatically return the roundabout to its normally elevated position, thus resetting the device Where it may again be used in the-manner as above described. It will thus be seen from the foregoing descriptionthat I have provided a roundabout which due to its simplicity may be manufactured at'a very lOW cost and will at all times be positive and efficient in its opera- Without departing from the spirit and scope of the appended claim.

Havi'ng'thus described the invention, What I clalm 1s A roundabout comprising in combination, a base, a spiral stem extending upwardly therefrom, a pair of standards arranged vertically on opposite sides of the spiral stem, ,a cross bar secured at its outer end to the upper ends'of the standards, a ladder arranged adjacent one of the standards, the upper end of the spiral stem being secured to the cross bar, the convolutions of the spiral stem being spaced With respect to each other to provide an inclined track, a vertical pin adapted for movement Within the con-' volutions of the spiral stem, intersecting cross members secured at their points of intersection to theinter'mediate portion of the vertical pin, seats arranged on the outer ends of the cross members and accessible from'said ladder, said cross members being adapted to rotate and simultaneously travel downwardly on the track formed by the spaced convolutions ofthe spiral stemby gravity, and a weight operatively connected to the upper end of the vertical pin for returning the same and said cross members to the top of the spiral stem.

In testimony whereof I aifix my signature.

WILLIAM- BROWN.
