COMBINED TEETER AND ROUNDABOU'I.
Specification of Letters Patent.
Application filedMay 17, 1920, Serial No. 382,108. Renewed May 19, 1921. Serial No. 470,951.
To all whom it may concern: 7
Be it known that I, EDMUND D. Gnovn, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in CombinedTeeters and Roundabouts, of which the following is a specification.
One object of my present invention is the provision of a combined teeter and roundabout of simple, durable and safe construction.
Another object of the invention is the provision of a combined teeter and round about embodying means whereby the operation of the apparatus may, when deemed expedient, be limited to teeter operations, as when it is desired to put a stop to the roundabout capacity of the apparatus by way of punishment for some infraction of rules.
To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.
In the accompanying drawings, hereby made a part hereof:
Figure 1 is a plan view showing my combined roundabout and teeter construction.
Fig. 2 is a side elevation of the same.
Fig. 3 is'a diametrical section through the central portion of the apparatus.
Fig. 4 is a detail view illustrative of the arrangement of the cushioning springs rel atively to the arms of each teeter.
Figs. 5 and 6 are detail views illustrative of the locking provision.
Similar numerals of reference designate corresponding parts in all of the views of the drawings.
At 1 is a vertically disposed sleeve maintained in position above a base 2 through the medium of stays 3, that are fixed to auxiliary bases 4. All of the bases referred to may be and preferably are formed of concrete.
Journaled in the sleeve 1 and stepped at its lower end in the base 2 is an upright post 5. The said post is preferably of three inch pipe, capped at its upper end and havits lower end plugged with Babbitt metal to afford an anti-friction wearing surface.
Pivotally mounted on the post 5 at different points in the height thereof and arranged at angles to each other are teeters 9, each of which has a central opening 10 receiving the post 5 and sufiiciently large for the required vertical oscillation of the teeter posite points and arranged under the arms of each teeter 9, are springs 15, there being two of the said springs to each teeter, and the springs being connected to the post 5 through the medium of a diametrical joint 16, and each spring having a curvilinear arm arranged under and in vertical alinement with one of the teeter arms. The springs serve to cushion the downward movements of the teeter arms, and in that way contribute to the elasticity of the teeter action and the pleasure of those using the teeters. It will also be appreciated that the springs 15 are safety factors, inasmuch as they preclude forcible striking of the teeter arms against the ground, as when weight is suddenly removed from one arm of a teeter, while weight is still imposed on the other arm thereof.
By virtue of the mounting of the revoluble post 5 in the manner described, it will be observed that the children on the teeter arms may use the apparatus as a roundabout, it being simply necessary for each child as it reaches the ground, to exert a sidewise push with one foot against the ground, whereby the post 5 and the parts carried thereby will be revolved about their common axis.
At is a rectilinearly movable bolt equipped with an eye 21 at its outer end and movable into and out of an aperture 22 in the revoluble post 5. Manifestly when the said bolt 20 is disposed in the aperture or socket 22 of the post 5, the apparatus is held against rotation and can then be used only as a teeter.
In combination with the said bolt 20, the outer portion of which is in the form of an upwardly directed arm 23, I employ a hinge thatcomprises a member 24 fixed to the base 2, and a vertically swinging member 25. The said member 25 is provided with two claws 26 adapted to drop and rest at the opposite sides of the bolt 20, and then when a Patented s t. 27, 1921.
This provision is advantageous, inasmuch as it renders it convenient to penalize children when guilty of some infraction of rules to the extent of limiting the operation of the apparatus to the teeter operation.
Having described my invention, what I claim and desire to secure by Letters-Patent, is: Y
1. In a combined teeter and roundabout, the combination of an upright revoluble post, base, means supporting the post, a
" teeter fulcrumed on and extending in opposite directions from the post, and means including a member connected to the base, a member detachably engaged with the first named member and engaging the post, and a lock to secure the second-named member against detachment from the first-named member whereby the post may be secured against unauthorized release for rotation.
2. In a combined teeter and roundabout, the combination of an upright revoluble post, means supporting the same, a teeter fulcrumed on and extending in opposite directions from'the post, a' bolt movable rectilinearly into and out of engagement with thepost and having an upturned outer arm terminating in an eye, and a hinge including a fixed member and'avertically swinging member having claws adapted .to .rest at opposite sides of the bolt arm below the eye thereon, whereby when a lock issecured in the eye the post and the parts carriedthereby will be locked against rotation.
3. The combination of an upright post, a teeter havingan opening in which the post is disposed. said teeter being pivotally c'on- EDMUND DAVIS GROVE.
