1 This invention relates to a novel construction of multiple playground equipment and more 'particularly to a combination swing and merry-goround which is occupant propelled.

More particularly, it is an object of the present invention to provide a combination swing and merry-go-round having a connection therebetween whereby the swing will be propelled by the occupant thereof for transmitting motion to the merry-go-round.

Still a further object of the invention is to provide a novel means whereby the oscillating motion transmitted by the swing is converted into a rotary motion for transmission to the merry-go-round.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawings, illustrating a preferred embodiment tional view of a portion of the clutch.

Referring more specifically to the drawings, the improved playground equipment in its entirety is designated generally 1 and includes a swing, designated generally 8 and a merry-goround, designated generally 9.

The swing 8 includes a supporting frame, designated generally I having upwardly and inwardly inclined legs I I at the corners thereof and which are connected at their upper ends to correspond- 'ing longitudinal side members I2 forming a part of the frame top. The side members I2 are connected at corresponding ends thereof by a cross member or red I3 which joins with the upper ends of two ofthe legs II. The upper ends of the other two legs I I are connected to the opposite ends of the side bars I2 by hearing members I4 which are interposed therebetween and which may be suitably connected to or formed integral with said last mentioned ends of the side members I2 and the two last mentioned legs II. The bearing members I4 are disposed in transverse alignment for journaling an end I5 of a shaft I8, which end I5 forms the other cross member of the frame top, but which differs from the cross member I3 in that it is rotatable relatively to the frame II).

The swing 8 includes two pairs of depending levers I1 and I8. The upper ends of the levers I! are keyed by collars I9 to the shaft portion I5 between the bearings I4 and the upper ends of the levers I8 are provided with aligned bearing portions 20 which are journaled on the cross member I3. The lower ends of the pairs of levers I1 and I8 are connected pivotally to the ends of a platform, designated generally 2| including substantially parallel side rails 22 which are journaled at their ends to individual levers I! and I8 by cross rods or shafts 23, one of which extends through and is journaled in the lower ends of the levers I1 and connected to corresponding ends of the side rails 22 and the other of which similarly extends through and is journaled in the lower ends of the levers I8 and connected to the opposite ends of the side rails 22. The platform 2I also includes two cross rails or rods 24, one of which is disposed adjacent to but spaced from each end of the platform 2I.

An occupant supporting seat 25 is supported between each of the pairs of levers I1 and I8, above but adjacent their lower ends, said seat 25 having pins or stub shafts 28 projecting from the ends thereof and which extend through and are journaled in the levers I1 and I8 for swivelly mounting the seats relatively thereto. The seats 25 are connected by a connecting bar 21 which extends therebetween and is connected at its ends to the undersides of said seats and a lever 28 is pivotally connected intermediate of its ends to the connecting bar 21 adjacent each seat 25 and approximately above the cross rod 24, disposed adjacent thereto. The lower ends of the levers 28 are pivotally connected to or journaled on the intermediate portions of the cross rods 24 and the upper ends of said levers 28 are provided with cross handles 29 adapted to be engaged by the occupants of the seats 25 who sit facing inwardly or toward one another with their feet upon the adjacent cross rod 24 and with their hands engaging the handle 29 so that by the execution of a backward and forward or oscillating motion on the handles 29 and accordingly on the upper ends of the levers 28, it will be readily apparent that the platform 2! and the levers I1 and I8 will be caused to swing as a unit longitudinally in the frame I0 and which'will also cause the shaft I8 to be oscillated in unison therewith.

The merry-go-round 9 includes a top portion 88 having depending and diverging legs 3| extending from the corners thereof and combining therewith to form the merry-go-round frame. A thrust bearing 32 is fixedly disposed on the sup porting surface of the legs 3| for journaling the lower end of an upwardly extending shaft 33 which is disposed substantially centrally of the merry-go-round frame and the upper end of which extends through and is journaled in a bearing} in'the central portion of the frame top 30.

A gear housing having an open flanged bottom is secured by fastenings 35 which extend through the flanges or ears 36 thereof and into the frame top 38, for detachably mounting said housing thereon. Said gear housing, designated generally 3?, is provided with bearings 38 in the ends thereof and in which the opposite end of the shaft It is journaled so that said shaftexztends longitudinally through the gear housing 3?. A bearing 3571's iournaled .on the shaft ltadjacent each end of the gear'housing 3'! and on the inner side thereof and'ach of said bearings 38 isprovided with a radially projecting flange 40 at its inner end. The fianges 46 are connected by means of fastenings M to annular bevel gears 52 and 4 5 name s s flie o p s e ons i o n another and which meshvwith diametrically ppfl es ep t e? a la u a tr st r-e gear-sit which is likewise disposed in-the housing 31 and keyed tn the pper, end'q the h ttea.
