COMBINED SEAT AND SEESAW.

SPEGIFICATION formingpart of Letters Patent No. 514,521, dated February 13, 1894.

Application filed April 25,1893. Serial No. 471,832. (No model.)

To all whom it may concern.-

Be it known that I, EMIL TORNBLOM, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in a Combined Seat and Seesaw, of which the following is a specification.

My invention consists of a simple plank lawn or play room seat readily convertible into a neat and practicable see-saw as hereinafter fully described reference being made to the accompanying drawings in which- Figure 1, is a front elevation of the bench. Fig. 2, is a side elevation of the see-saw. Fig. 3, is an elevation of the see-saw as seen in the longitudinal direction of the seat. Fig. 4, is a side elevation of the fittings of the pivotal supports of the see-saw, enlarged.

I provide a couple of shaped frames as a, b, having a suitable breadth of base for substantial self support with foot bars (1, attached to and on which the lower ends of the legs of each inclined side of the frame rest respectively, said frames being of suitable height for the support of the plank e, as a seat on a cross barf, at the apex of each frame.

To the ends of one of the cross barsf, I attach metallic plates as 9, having a notch 71 in the upper end and to the other of said cross barsI attach other plates as 2' having a counter part bearing rib j, adapted to rest in said notches for pivotal connection of the two frames, one being inverted and placed on the other and on the upturned base of the inverted leg frame I mount the seat plank, said plank having the transverse dovetail cleats is, attached to the under side in the middle portion and in suitable relation for reception of the foot bars, the outer edges of which are suitably beveled to make connection with the dovetail cleats by sliding in between them sidewise of the plank.

While I prefer the dovetail cleat arrangement for connecting the leg frame and plank I will avail myself of any other approved means of readily connecting them detachably, and I do not limit myself to the form of pivot fittings shown as they may be modified at will.

I claim 1. The combined seat and see-saw comprising the leg frames adapted for independent support and for detachable pivotal connection at their apexes, and the seat plank adapted for detachable connection at the middle to the base of the mounted leg frame substantially as described.

2. The combined seat and see-saw comprising the leg frames adapted for independent support and having the foot bars attached to the lower ends of'the legs, and also having the fittings of a detachable pivot connection attached to the top, and the seat plank having the transverse dovetail cleats adapted for the connection of the base of one of the leg frames at the middle of the plank substantially as described.

In testimony that I claim the foregoing as my invention I have-signed my name, in presence of two witnesses, this 8th day of April, 1893.

EMIL TORNBLOM.
