Application filed December 9, 1921. Serial No. 521,107.

To all w 710% it may concern: I 7

Be it known that I, WVILLIAM A. FLINT,

a citizen of the United States, residing at New Haven, in the county of New Haven 6 and State of Connecticut, have invented certain new and useful Improvements in Teeter Boards, of which the following is a specification, reference being had therein to the accompanying drawings. p

This invention relates to teeter boards and it is the object thereof, among other things, to provide an amusement device that may be of such shape and construction that it may be readily assembled and taken down 5 with the minimum labor and skill, whereby the same may be readily portable and when taken down will occupy the minimum space.

Among other aims and objects of the invention, may be recited the provision of a 20 device of the character mentioned with a view to compactness and in which the number of parts are few, the construction simple, cost of production small and efficiency andoperation high. I

The details and arrangement of parts will be apparent from an inspection of the accompanying drawings in connection with the description hereinafter contained and wherein a preferred embodiment of the in- 3 vention is disclosed for the purposeof imparting an understanding of the same' In the drawings, Figure 1 is a perspective view of my improved teeter board; 35 Figure 2 is an elevation of the stand in its closed position; and

Figure 8 is an enlarged fragmentary sectional view of some of the parts, taken generally upon line 3-3 of Figure 1.

Having more particular reference to the drawings in connection with which like reference characters refer to corresponding parts, 10 designates the board upon the top side of which and near the outer ends there 45 of are the uprights 11 which are movably connected therewith by the hinges 12 and locked in their upright positions by the latch or hook 13. Each of these uprights have a handle 14 that projects laterally upon either side thereof near its upper end.

The hinged connection between the up rights and the board enables the former to fold down onto the top of the latter when desired, thus insuring compactness of the parts.

' The. stand which are preferably arranged in pairs, hav ing braces 16 near the top and bottom thereof and hinged together near their upper ends by means of the plates'1-7 and pins 18. When the stand is in its openposition,

the legs are held apart bythe lock brace 19 which is of awell known type and comprises two arms 20 which are respectively hinged-to each other by the pin 21,'to legs 15 by the pin'22, and having a stop 23 thereon that registers with a notch 24 in one of the arms when the same are in their extended position.

' Upon the inner face of each of the legs '15 near the upper end is a recess 25 semi-circular in form, which unite when the stand is in its open position to form circular bearings 26 for the cylindrical portions 29 of the shaft 27, which is fixed to the board 10 midway between its ends by the bolts 28 or.

similar means when the parts are assembled, thus providing a rotary locked support for the board 10.

When assembled, as shown in Figure 1, all of the parts are so connected with each other as to be locked against any accidental disengagement, thus making the device entirely safe for use. It may be, taken down very readily by merely folding up the stand so that the legs abut against each other as shown in Figure 2, which movement causes the recesses 25 to travel away from each other and open the bearing 26, releasing the shaft 27. The board 10 is now lifted therefrom, and the uprights 11 moved to their down positions, the several parts thus occupying the minimum space either for storage purposes or for transportation, as may be desired.

Obviously the details of my invention may be materially altered within the terms and spirit of the appended claims and I do not therefore limit myself to the exact construction herein shown and described.

What I claim as new-and desire to secure by Letters Patent, is:

1. In an amusement device; a board; a shaft connected therewith; a collapsible stand, composed of a plurality of legs hinged together in pairs, each leg having a face at is constructed with legS 15f fit its upper inner end with a semi-circular recess therein that Wlll contact With a simi- ,lar face upon the other leg hinged thereto when said legs are in their open position and thereby limit the relative movement of said legs in one direction, at which,:time said semi-circular recesses will unite to form a journal bearing for said shaft which will rotate freely therein; and means for holding said stand against closing when in its open position.

2. In an amusement device; a board; a shaft connected therewith; a collapsible stand, composed of a plurality of legs hinged together in pairs, each leg having a face at its upper inner end with a se1ni-circular recess therein that will contact with a similar face upon the other leg hinged thereto when said legs are intheir open position and thereby limit the relative movement f Said; legs in one direction, at hi h timesaid semi-circular recesses will unite to form a Journal bearing for said shaft which will rotate freely therein; means for holding said stand against closing when in its open position; and an upright hinged to the said board near both ends thereof.

3.In an amusement device; a board; a shaft connected therewith; a collapsible stand, composed of a plurality of legs hinged together in pairs, each leg having a face at its upper inner end with a semi-circular recess therein that will contact with a similar face upon the other leg hinged thereto when said legs are in their open position and thereby limit the relative movement of said legs in one direction, at which time said semi-circular recesses will unite to form a journal hearing for said shaft which will rotate freely therein; means for holding said stand a ainst closing when in its open position; an upright hinged to the said board near both ends thereof; and. means for locking the same in their up positions.

In testimony whereof, I have hereunto affixed my signature.

WILLIAM A. FLINT.
