Claims. (Cl. 272-33) This invention relates to improvements in merry-go-rounds and has particular reference to a childs manually operable device.

The principal object of the present invention is the provision of a merry-go-round having foot and hand propulsioned. means whereby the merry-go-round is operated.

Another object of this invention is the provision of a merry-go-round having manually operable propulsion means whereby the device may be rotated in either direction.

A further object of the invention is the provision of a merry-go-round so constructed as to preclude to a large degree any possible injury to the children.

Other objects are simplicity and sturdiness of construction, ease and efficiency of operation, and adaptability for use by children of different ages.

With these objects in view, as well as other objects which will appear during the course of the specification, reference will be had to the drawings wherein:

Figure 1 is a plan view of a merry-go-roun embodying this invention.

Fig. 2 is a side elevation of the merry-goround shown in Figure 1.

Fig. 3 is a cross sectiona1 view of the merrygo-round taken on line III-III of Figure 1.

Fig. 4 is an inverted view of the base or track construction.

Fig. 5 is an enlarged sectional view taken on line VV of Figure 2.

Fig. 6 is a modified form of the base, provided with a vertically undulated track.

Throughout the several views like reference characters refer to similar parts and the numeral l0 designates a base section having a central post [2 on which is mounted a bracket 14 which is securely attached by means of a pin l6. Radial arms [8 are rigidly attached at their inner ends to bracket [4 by any suitable means so that they may be disengaged for shipping. It is quite conceivable that they might be riveted or welded together when they are permanently located.

Mounted on the outer extremities are a series of track members 20 which are rigidly attached by means of rivets 22. These track sections may be made of planar sheets of plywood, metal or any other suitable material. It will be noted that the arms l8 are made of T iron with depending ribs which tend to hold the base against movement relative to the ground surface. The central post 12 is disposed perpendicular to the 2 plane of the track 24 and extends below the bracket 14 to engage in the ground below the base member. This extension serves to positively set the merry-go-round in a given position.

Slidably mounted for vertical adjustment on post I2 is a bracket 26 similar to that of bracket [4, and having radially disposed arms 28 made of T irons and provided at their outer extremities with seats 39 which are secured in position by means of rivets. Intermediate the ends of each of said radial arms is a depending bracket 34 having a horizontally disposed radially projecting axle member 36 on which are rotatably mounted wheels 38 which are adapted to rest on track 24 and which support the load of the revolving member 40.

The arms 28 are joined together by aseries of segmentally disposed bars 42 which extend entirely about member 40, just inside the seats 30. Each child positioned in the various seats is provided with an individual, manually propulsioned means M. Each of these propulsion members is identical in structure and comprises a bearing bracket 46 rigidly aflixed to 'bar 42 which is provided with a bearing member 48 having its axis parallel with the axis of the adjacent wheel 38.

Rotatably mounted in bearing 48 is an oscillatable axle 50 shouldered at 52 at one end of the bearing and having a right angled depending arm 54 at the other end of said bearing. A driving link 56 pivoted at its one end to a pin 58 disposed eccentrically on the face of wheel 38 is pivoted at its other end to the lower extremity of arm 54 by means of pin 60. The outer extremity of axle 52 is provided with a U-shaped propulsion member 52 having an upper hand grip 64 and a lower foot rest, so positioned relative to the adjacent seat 30 that the child may conveniently engage the hand grip 64 and the foot rest 66 to oscillate axle 5|], and through the connections just described, cause wheel 38 to rotate to drive the rotatable member 40 either forwardly or backwardly.

It is quite apparent that with this construction the rotary member may be operated by one child, or by any number up to the limit of six, and at all times the weight of the child or children will be directly over the respective traction wheels 38, thus insuring a sufilclent traction force to cause the merry-go-round to rotate.

While in the preferred form the track 24 is shown and described as planar; however, in the modified form shown in Figure 6 the track 68 i undulated vertically so as to cause a suitable vertical movement of the revolving member, including the seat, traction wheel, and propulsioned means, to simulate the customary up and down movement of the ordinary power merry-go-round.

In order to obtain traction on all the Wheels in like manner, it is necessary to provide the same number of undulations as there are traction wheels, or a multiple thereof, thus insuring that each wheel at all times will be resting on similar track contours.

The sliding movement of bracket 26 on the cen-. ter post [2 will permit of vertical movement of the rotary member 40 without interfering with the proper control of said member.

What we claim as new and desire to cover'by Letters Patent is:

1. A merry-go-round comprising a base forming a substantially circular track having equally spaced vertical undulations therein and carrying azvertically disposed center; post, ,a rigid 'member mounted for rotation and vertical movement on said center post, .vvheelsrotatably carried by said rotatablemember and, adapted to rest on said track; saidlwheelslbeing equal in number tothe undulations ofjsaidztrack andequally spaced circumferentially, about said: track, seats, mounted on :said rotatable member andmanually operable propulsion means carried .by said rotatable meme ber,.whereby a child positioned in one of, said seats may operate said propulsion meansto cause said rotatable member to move.
