UNITED STATES HARVEY M. SYKES, 0F TOLEDO, OHIO.

srnrne a nn'rna.

Application filed January 8, 1923.

To all whom it may concern:

Be it known that I, HARVEY M. SYKEs, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have made an invention appertaining to a Spring Teeter, which invention is fully set forth in the following specification.

My invention has for its object to provide a spring teeter for elastically supporting children whereby they may enjoy the pleasure of being rapidly raised and lowered, an experience that makes the well known teeter such a desirable pleasure for children. By my invention is provided a means whereby a single child may have the pleasure of teetering, while in the well known teeter two or more children are required to counter-balance the teeter board. The invention also provides a means where- 'by the weight of the child is automatically counter-balanced, the eflect being merely to depress the teeter slightly more in the, case of a child of heavier weight.

Constructions containing the invention may be varied in the structure of their details. To illustrate a practical application of the invention I have selected a construction containing the invention as an example and shall describe it hereinafter. The construction selected for purposes of illustration is shown in the accompanying drawings.

Figure 1 of the drawings illustrates a topview of the spring teeter. Fig. 2 illustrates a side View.

In the figures, 1 indicates a board that constitutes the base or support of the teeter. At one end of the board is provided a suitable pedestal or bracket. The pedestal or bracket may be secured to the board 1. As shown in the figures, the bracket is a bar bentin the shape of an inverted U. The bracket 2 is provided with the sides 3 and the top 4. The lower ends of the sides 3 are bent laterally so as to receive the bolts 5 by means of which the bracket is secured to the board 1. A brace 6 extends diagonally from the corner formed between one of the sides 3 and the top 4: and located near the end of the board 1. The brace 6 is secured by bolts 7 to the sides 3.

Two tempered steel springs 8 and 9 are secured by bolts 10 to the top 4 of the bracket 2. The spring 8 extends substantially the length of the board 1. Its free Serial No. 611,235.

end is provided with a cross board or seat 11. The child who uses the device may be seated upon the board 11 and the spring 8 will be slightly depressed. The child may be supported by the elasticity of the spring 8. The spring 9 extends diagonally upward and its outer end portion 12 is bent to substantially horizontal, that is, at an angle to the body portion of the spring 9. To the end of the spring 9 is secured a cross bar or wooden handle 13, the ends of which may be grasped by the child seated on the board'll. Pulling on the handle 13 will transfer a large part of the weight of the child from the spring 8 to the spring 9, which causes the pressure of the spring 9 and elevation of the spring 8. Releasing ofthe weight or pull on the handle 13 will cause the spring 8 to again be depressed, the releasement occurring when the spring 8 has'been raised to its uppermost position. Releasement causes the spring 8 to be depressed, and by reason of the momentum produced it will be depressed considerably below the point that it will be depressed by the weight of the child alone. Repeated operations on the spring 9 occurring substantially synchronous with the limits of the movements of the spring 8 will produce the bounding efiect which gives the child the pleasurable experience sought and which is not produced in the ordinary teeter board, the teeter board producing only that up-and-down springing movement, but not the bounding movement which is more highly appreciated by the child.

I claim:

1. In a spring teeter, a pair of tempered.

steel springs, a supporting board, means'for connecting an end of each ofthe springs to one end of the board, one of the springs for supporting a person well above the HARVEY M. SYKES.
