ROBERT W. JAMISON, or mandates, CALIFORNIA;

COMBINED MEBRY-GO-ROUND AND SEESAW.

Application filed May 27,

This invention relates to amusement devices in the nature of seesaws and the general object of the invention is to provide a. very simple seesaw designed to be used by children which at the same time will provide a device in the nature of a merry-go-round or, in other words, in which the seesaw is mounted for rotational movement about a center.

A further object is to provide a construction of this character which is very simple, which may be readily assembled, which is strong, and which may be readily shifted.

Another object is to so dispose the point of suspension for the seesaw that it is above the points of application of the load, thus lessening friction and securing a better balance. I

My invention is illustrated in the accompanying drawings wherein Figure 1 is a side elevation of a combined merry-go-round and seesaw constructed in accordance with my invention;

Fig. 2 is a top plan view of the structure shown in Figure 1 with parts broken away on the line 2-2;

Fig. 3 is an enlarged fragmentary elevation showing the manner of supporting the seesaw, the block 14 being partly broken away.

Referring to these drawings 10 designates an upright as, for instonce, an iron pipe or rod which, at its lower end, is supported in a suitable base. As illustrated the base consists of a block 11 to which are bolted four angularly disposed legs 12, these legs engaging against the side faces of the block and there being preferably three bolts in each leg, two of the bolts extending through the upper end of the leg and the third bolt extending transversely across the upper end of the leg to prevent the leg from slipping under strain.

The upright 10 at its upper end is provided with a ball 13 which operates within a socket formedin a triangular block 14. The lower face of this block is horizontal and the two upper faces extend downward and outward. Extending horizontally on each side of the pipe 10 are two parallel beams 15, the extremities of which are bolted to each other and to the lower ends of the downwardly diverging truss rods16. The upper ends of 1926. Serial No. 112,081.

these rods rest against the block 14 and are bolted thereto with their meeting ends hinged as at 16. An iron 17 extends over the upper ends of these trusses 16 and bolts 18 pass through the block 14 through the upper ends of the truss rods and through this iron. These rods 16 extend downward and outward and pass between the beams 15 to a point somewhat beyond the extremities of these beams and a bolt 19 passes through the end of each rod 16 and through the ends of the beams.

Mounted upon the projecting ends of the beams 15 are the seats 20, each of which is bolted to a cross piece 21 attached to the corresponding truss rod. Forming part of each seat is the animal head 22 which is bolted by a plurality of bolts to the corresponding truss rod 16. Handles 23 extend through the animal head 22 and preferably these handles 23 are disposed sufficiently high above the seat 20 as to cause a child sitting on the seat to take an upright position while riding.

It will be understood that the beams 15 are disposed sufficiently near the ground so that children sitting on the seats 20 can just touch their feet to the ground. This permits the children to oscillate the seesaw upon the center formed'by the ball 13 and its corresponding socket and also permits the children to cause the rotation of the seesaw around the vertical axis 10. Obviously, a combined movement may be secured wherein the seesaw is not only intermittently tilted but also turned around its vertical axis. It is to be particularly noted that the point of suspension for the seesaw is above the weight of the children on the seats 20. This se cures a much better balance and much easier movement both for rotation and oscillation of the seesaw and lessens friction.

While I have illustrated certain details of construction and arrangements of parts which I have found to be particularly effective in actual practice I do not wish to be limited thereto as it is obvious that many changes might be made therein without departing from the spirit of the invention as defined in the appended claim.

I claim An amusement apparatus comprising a vertically disposed standard, said standard being provided at its upper end with a ball structure, a block having a recess receiving the ball, truss members mounted upon the block and extending beyond the ends thereof and anticlined with relation to each other,

5 side beams connected with the end portions of the truss members and bridging the space between them, said side beams being dis posed one at each side of the standardyand seats carried at the ends of the side beams and truss members. 10 p In testimony whereof I hereunto aflix my signature.
