TEETER-BOARD ND STAND THEREFOR.

SPECIFICATION forming part of Letters Patent No. 624,832, dated May 9, 1899.

- Application filed May 5, 1898. Serial No. 679,843. (No model.)

To all whom, it may concern:

, Be it known that I, BILL G. LOWREY, a citizen of the United States, residing at Blue Mountain, in the county ofTippah and State of Mississippi, have invented certain new and useful Improvements in Teeter-Boards and Stands Therefor; and I do hereby declare the following to be a fulhclear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in I devices for the amusement of children; and

it consists of an improved form of teeterboard and stand for thesame, the construction and arrangement of which will be hereinafter fully described and claimed.

Referring to the accompanying drawings, in which the same parts are designated by the same letters of reference throughout the several views, Figure 1 represents a side view of my device in position for use. Fig.2 is an in verted plan view of the teeter-board. Fig. 3 represents an elevation of the stand or trestle for the same looking from the right-hand side as seen in Fig. 1, and Fig. dis a vertical sectional View taken on the line 4 4 of Fig. 3.

A designates the beam of the trestle, which is beveled along the upper edges, as at a, and may be rounded at the top, as at a. l The said beam is out out at the top near the middle, as at A, leaving the shoulders a and at each end of the said cut-out portion is formed a shoulder A for the teeter-board to rest upon, and the said. shoulders A are plated with .metallic plates a to strengthen and reduce the wear upon the same.

The beam A is supported upon the legs B, which are mortised into the sides of the said beam ne ,1 the ends thereof, as shown by the dotted lines a in Fig. 4:, and are held in place by the bolts and nuts 0, passing through the said beam and legs.

The legs B are each formed in two sections B and 13*, one of which sections, as B is provided with clips I) at one end, which ex tend over the edges of the other section and are arranged to slide thereon, and the other section B is provided with a bolt 1), which extends through a slot 11 in the first-mentioned section B and the said bolt is provided with a thumb-nut b by means of which the two'sections may be clamped together at any desired adjustment. Thus it will be seen I that by loosening'the thumb-nut b the two sections may be moved one upon theother to lengthen or shorten the legs and so vary the height of the beam A. f

The upper sections of the legs B are provided with slots 12 through which the bolts 0 are arranged to pass, and by loosening the nuts and the bolts 0 the legs may be drawn downwardly until their ends are out of the mortises a, and the said legs may then be turned upon the bolts 0 and laid parallel with and against the sides of the beam A, thus folding the device into a very small space for stor ing or transportation.

The teeter-board is formed in two sections D and D and these sections are provided at their meeting ends with clips (1' and 01 which extend over the edges of the other sections and allow the two sections of the teeter-board to slide one upon the other, as will be readily understood.

One of the sections of the teeter-board, as D, is provided with one or more holes d or with a stop to receive the bolt (1 which is arranged to extend through a slot d (shown by dotted lines in Fig. 2) in the other section D and the'said bolt is provided with a nut (1 by means of which the two sectionsmay be clamped together-at any desired adj ustme'nt; From the foregoing it will be seen that the teeter-board may be lengthened or shortened at will and clamped firmly at the desired length.

The teeter-board is' provided with one or more seatsE at each end-thereof, and the board is reduced in width, as at 61?, just in front of the said seats, these reduced portions serving the double purpose of enabling a small child to straddle the board without inas above described, or the nut 61 may be loosened and the two sections slid together and clamped in the shortest position.

The teeter-board is provided along its edges on the under side with a series of small indentations'or sockets d to rest upon the shoulders A of the beam A of the trestle and prevent the board from slipping upon the said tiou; of a teeter-board composed of two sec-i beam. By providinga number of these sockets dthe fulcrum of the board may be changed at will, as will be readily understood. The sockets d are preferably plated with metal, as at e, to reduce the wear on the same.

The method of operating the device will be clearly understood from the foregoing, and the advantages thereof will be apparent to those skilled in the art to which it appertains.

Having thus described my inventiomwhat Iclaim, and desire to secure by Letters Patent of the United States, is

1. In a device of the character described; the combination with a beam having supports; and having a portion of its upper surface'cuti away at a'uniform depth, and curved bear-i ing-plates secured within said cut-away por-l tions overlapping at one end and adj ustablej longitudinally with respect to each other,

clips upon the overlapping end of one section justments, concave bearing-plates secured,

curved bearing-platessecured within said cut away portion upon the upper side of said beam, the upper surface of said bearing-plates being below the upper surface of said beam upon the sides of said-cut-away portion; of a teeter-board composed of two sections overlapping at one end and adjustable longitudinally with respect to each other, clips upon the overlapping end of one section engaging the other section, and an adjustable bolt work ing in parallel slots in said sections for clamping the said sections together at different adjustments, concave bearing-plates secured upon the under side of one of said sections of the teeter-board, the said concave bearingplates being adapted to fit upon andmove over the convex bearing-plates upon said beam substantially as described. In testimony whereof I aff x my signature in presence of two witnesses.
