FOLDING SEESAW.

SPECIFICATION forming part of Letters Patent No. 505,485, dated September 26, 1893.

Application filed May 5, 1893. Serial No. 473,127. (No model.)

.To all whom it may concern.-

Be it known that I, EDWARD M. SOEARCE, a citizen of the United States, residing at Paris, in the county of Monroe and State of Missouri, haveinvented a new and useful Folding Seesaw, of which the following is a specification.

, The invention relates to improvements in see-saws or teeters.

to The object of the present invention is to provide a simple and efficient see-saw adapted to be folded compactly when not in use, and

capable of being adjustedin size and height to suit the room or space in which it is to be r 5 used, to accommodate and balance persons of difierent sizes and to adapt itself to large and small children of both sexes.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figure 1 is a perspective view of a see-saw constructed in accordance with this invention. Fig. 2 is a side elevation showing the see-saw folded. Fig. 3 is a central transverse sectional view. Fig. 4. is a detail sectional view taken transversely of the beam sections at the inner end of one of them to show the double rectangular hook. Fig. 5 is a detail perspective view of the loop. Fig. 6 is a similar view of one of the double rectangular hooks. Figs. 7 and 8 are detail perspective views of the hinge castings. 3 5 Like numerals of reference indicate corresponding parts in all the figures of the drawlugs.

1 designates a stand of substantially pyramidal shape composed of four inwardly inclined legs 2 connected in pairs near their lower ends by transverse rungs 3 and hinged together at their upper ends at the sides of the stand by hinge castings 5 and 6.

The hinge castings 5 and 6 are provided 5 with semi-sockets 7 and 8 and have offset inclined eyes 9 and 10 provided with openings to receive a pivot bolt 11, which also pivots 0r fulcrums a rectangular loop 12 at the top of the stand between the sides thereof. The

legs; the hinge casting 6 has its top flange formed by offsetting outward the eye 10; and the hinge casting 5 is provided at the top of its semi-socket with a separate flange 13 and its eye is offset slightly inward. The opposed faces of the eyes 9 and 10 areprovided around their openings with annular enlargements 14 and 15.

The rectangular loop 12 is provided at its 50 ends with depending integral cars 16, and it serves as a guide and keeper for adjustable beam-sections 17 provided at their outer ends with pivoted seats 18, and each havingat its innerend a double rectangular book 19. The beam sections are capable of longitudinal adj ustmentto increase and decrease the length of the beam to enable the see-saw to accommodate itself to the space in which it is used, and the beam sections may also be unequally adjusted to vary the length of the arms or sides of the beam to enable a lighter person to balance a heavier one.

The double rectangular hook is secured at the inner end of each beam-section, and it 7 extends over the top of the beam section to which it is secured and under the bottom of the adjacent beam section to form a guide and support for the same. The inner end of each beam section is provided on its lower face with a depending stud or projection 20 to limit the outward movement of the beam sections to cause the same to lap sufiiciently.

The pivoted seats 18 are adapted to be turned sidewise or straight to allow persons 8 to sit sidewise of the beam, or astride of the same to accommodate persons of either sex, and the arms of the seats are provided with locking bars 22 to enable small children to see-saw with safety. The seats are provided on their lower faces with stops to engage the beam sections to prevent them turning too far.

The stand is adjustable in height to enable the beam-sections, which are" arranged side 5 by side, to be raised and lowered to-accominodate large and small persons; and to accomplish this the legs of each side are pro vided with adjusting perforations23, which are adapted to receive bolts or screws to attach 10o pivoted connecting bars 24 to the legs. The link-bars have their inner ends hinged or pivoted together; they limit the separation of the legs and they permit the same to be folded. By raising and lowering the linkbars on the legs the stand may be diminished or increased in height.

It will be seen that the see-saw or teeter is simple and inexpensive in construction and strong and durable, that it is capable of being readily adjusted to suit the character of the persons using it and the place in which it is to be used, and that it is adapted to afford safe amusement and exercise.

Changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention.

What I claim is 1. A see-saw comprisinga stand having legs, hinge castings secured to the tops of the legs and provided with half-sockets to receive the legs and having inclined offset eyes, a rectangular loop provided with depending eyes, a pivot bolt passing through said eyes and hinging the castings together and fulcrn ming the loop on the stand, the longitudinally adjustable beam sections slidingly arranged in the loop, and seats secured to the outer ends of the beam sections, substantially as described.

2. Asee-saw comprisingastand havinglegs, hinge castings having inclined oifset eyes and provided with half-sockets receiving the upper ends of the legs and consisting of plates and side and top flanges, a rectangular loop provided with depending eyes, a pivot bolt passing through said eyes, beam sections arranged in the loop, and seats mounted on the beam sections, substantially as described.

3. In a see-saw, the combination of a stand, a rectangular loop fulcrumed on the stand, beam sections slidingly mounted in the loop and arranged side by side and capable of longitudinal adjustment, and the double rectangular hooks arranged at the inner ends of tions and each extending over the top of the Y beam section to which it is secured and under the adjacent one, and studs projecting from the lower faces of the beam sections and arranged near the inner ends of the same, substantially as described.

5. In a see-saw, the combination of a stand, a loop fulcrumed on the stand, beam sections slidingly mounted in the loop and arranged side by side, and double hooks arranged at the inner ends of the beam sections and each extending over the top of the beam section to Which it is secured and under the bottom of the adjacent one, substantially as described.

6. In a see-saw, the combination of a frame having legs arranged in pairs and provided with adjusting perforations, hinged link bars arranged at the sides of the frame and connecting the legs and provided with fastening devices adapted to enter any of the perforations, hinge castings secured to the upper ends of the legs and provided with eyes, a loop provided with depending eyes, a pivot bolt passing through said eyes, beam-sections arranged in the loop and capable of longitudinal adjustment, and seats mounted on the beam-sections, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

EDWARD M. SCEARCE.
