SEESAW, MERRY-GO-ROUND, AND LAWN-SEAT.

srnorrrcATroN forming part of Letters Patent No. 666,992, dated January 29, 1901.

Application led October l0, 1900. Serial No. 32,620. \.No model.)

To a/ZZ whom, t may concern:

Be it known that I, FRANK L. WRIGHT, a citizen of the United States, and a resident of Nyack, in the county of Rockland and State of New York, have invented a new and Improved Seesaw, Merry-Go-Round, and Lawn- Seat, ot' which the following is a `full, clear, and exact description.

The purpose ot' the invention is to provide an article for the amusement of children known as a seesaw and to so construct the article that the teeter-board will have not only a vertical pivotal motion, but may be swung horizontally upon its pivot, a ball-andsocketconnection being provided between the teeter-board and its support, and, further, to provide means whereby the teeter-board may be converted into a lawn-seat.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures. i Figure lis a side elevation of the improved Fig. 2 is a vertical transverse section drawn on an enlarged scale, the section being taken practically on the line 2 2 of Fig. 1. Fig. 3 is a horizontal section taken practically on the line 3 3 of Fig. 1 looking upward; and Fig. 4 is a side elevation of one end portion of the teeter-board, illustrating the application of legs thereto.

A represents a teeter-board, which may he of any desired dimensions, and at the central portion of the under face of the board A a rockerblock 11 is secured by means of screws 10 or other fastening devices, and the bottom surface 12 of the said rocker-block is preferably convexed, so that when the rockerblock is mounted on a suitable pivot the ends of the teeter-board may drop and rise to the greatest possible degree. The rocker-block 11 is provided with a socket 13 in its under face at the center, the upper wall of which socket and adjacent portions of the side Wall being hemispherical and the remaining portions of the side walls more or less straight, as shown in Fig. 2. This socket is adapted to receive aball14, which tits more or less closely in the hemispherical portion of the socket 13, as shown in Fig. 2. Ashank 15 is rigidly secured to the ball 14, and this shank is attached firmly in the upper portion of the headblock 16 of a stand B, which st-and is preferably provided with three legs 17, so that it is in the form of a tripod.

In order that the rocker-block 11, attached to the teeter-board, shall not leave the ball 14, a plate 1S is secured to the bottom surface of the rocker-block, extending across the bottom of the socket 13, and at the socket 13 the plate 18 is provided with a transverse slot 19, which extends longitudinally ot the teeterboard, as shown in Fig. 3, and the shank 15 of the ball 14 passes through this slot. Preferablythe rocker-block 11 is not in engagement with the head-block 16 of the stand or tripod.

The teeter-hoard may be converted into a lawn-seat whenever desired by hinging or pivoting legs 2O to the under side of the board near its ends, as shown in Fig. 4, which legs when resting on the ground will hold the teeter-board in a horizontal or stationary position. When the legs 20 are not required, they are carried up beneath the teeter-board and secured thereto by hooks 22, carried by the board, arranged to engage pins 21 upon the legs.

It will be observed from the foregoing construction that a practical, safe, handy, and portable seesaw is obtained tor the am useinent of children, aud the teeter-board may have not only the usual up-and-down movement at its ends, but may be moved horizontally as desired and turned around more or less rapidly upon its pivot-support, making the board a turning board as well as a seesaw-board.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a seesaw, the combination, with a teeter-board and stand, of a rocker-block having a convexed under face and a socket produced centrally in the said convexed face, the upper portion of which socket is hemispherical, a ball fitted to the hemispherical portion of the said socket, a shank attached to the ball and secured in lthe upper portion of the stand, and a plate secured to the bottom of the rocker-block, which plate is provided with IOO an elongated slot extending longitudinally of the teetenboard and through which the stem of the ball is loosely passed, but through which slot the ball itself cannot pass, for the purpose specified.

2. In a seesaw, the combination with a teeter-board and stand', and a hinged support for the ends of the board, of a rocker-block secured to the under surface of the board and provided in its under face with a socket, a ball fitted to the socket and provided with a shank, and a plate secured to the bottom of the rocker-block and having a slot extending longitudinally of the hoard and through which slot the shank of the ball loosely extends, the said shank being secured to the stand, substantially as described.

3. A teeter-board provided with a socket on its under face, a ball fitting in said socket and provided with a shank, and a plate secured to said teeter-board and extending over the month of the socket, the said plate having an elongated slot extending longitudinally of the teeter-board, the shank of said ball extending loosely7 through the slot in said plate and secured to a support, as set forth.

. In testimony whereof'` I have signed my name to this specification in the presence of two subscribing Witnesses.

FRANK L. W RIGHT.
