JOHN B. TYLER, OFV BROOKLYN, ASSIGNOR OF ONE-HALF HIS RIGHT TO THOMAS DAVIES, JR., OF GREEN POINT, NEW YORK.

IM PROVEMENT IN, SEESAWS.

Specication forming part of Letters Patent No. 201,897, dated April 2, 1878; application filed January 5, 1878.

To all lwhom it may concern:

Be itv known that I, JOHN B. TYLER, of Brooklyn, ofthe State of New York, have invented a new and Improved Nursery-Seesaw, of which the following is a speciiication:

My inventionconsists in the arrangement of a seesaw, which can be extended when required for use, or closed up when not in use, so as to occupy only very little space.

In the accompanying drawing, Figure I represents a longitudinal side elevation of myimproved seesaW extended for use. Fig. II is a top view of the same, and Fig. III is a crosssection of the box-beam.

A represents the frame or stool supporting the seesaw, made with an open jaw, B, in which a box-beam, C, turns on centers a. To the ends of this beam O springs D are attached,

fastened. to a central bolt, E, fixed in the framing. In the box-beam C two arms, F and G, are made to slide. The sides of the box-beam are provided with grooves n n, in which wheels s s, attached to the arms F and G, are made to work, and through which said wheels these arms F and G are guided in their motion inwardly and outwardly. In the ends of the boxbeam pins fw are fixed, fitting into suitable holes in the under side of the arms F and G, when the same are pulled out to their desired extent, so as to hold said arms in this'position, lookin g the same fast while the seesaw is in operation. On the outer end of the arm F a seat, J, similar to a saddle, is arranged, provided with a projecting cross-bar, H, andv on the outer end of the arm G a seat, K, simi lar to a chair, is arranged, suitable to receive a girl, and provided with aprojecting cross-handle, H. This chair-seat K is made to turn partly around on thearm G by means of a center-pin, w, to enable seating the girl upon the same sidewise, in a position similar to a seat upon a horse.

When the seesaw is not in use the arms F and G are slightly lifted upward, so as to come clear of the locking-pins w, and are then moved inward, as shown in dotted lines in Fig. I, occupying thus but very little space.

I claim as my invention, and desire to secure by Letters Patentl. The combination of the frame A, with open jaw B, box-beam C, springs D, and sliding or extending arms Fl G, arranged to operate in the manner and for the purpose described.

2. The box-beam C, provided with grooves d a n, in combination with wheels s s attached to the sides of the slidingarms F G, substantially as specified.

3. The pins w in the ends of the beam C, in combination with the sliding arms F and G, for the purpose set forth.

4. In combination with sliding arms F and G, arranged to operate for the purpose described, the saddle-seat J on the end of one arm, and the chair-seat K, capable of turning on its center-pin w at 'the end of the other arm, and the projecting cross-arms H and H', substantially in the manner and for the purpose herein specilied.

JOHN B. TYLER.
