'Unirse STATES ROBERT WENNEasTaoM, or NEW YORK, N. Y.
ROTATING CHAIR.
Application led June 23, 1922. Serial No. 572,353.
To all 'Lv/wm t may concern:
Be it known that I, ROBERT WENNER- s'moM, a citizen of the United States, and resident of the city of New York, in the county of Bronx and State of New York,
have invented certain new and useful Improvements in Rotating Chairs, of which the following is a specication.
The present invention relates to an amusement device in the form of a chair.
The main object of the invention is to provide a chair which furnishes a cheerful diversion to the user by having its seat rotatably mounted on a base, in combination with manually operated means whereby rotation may be imparted bythe occupant of the chair to the said seat in either direction and the speed of rotation may be varied at will.
Another objectcof the invention is to produce a chair of the character mentioned which is simple in construction, eiicient in operation, durable in use and capable of manufacture on a commercial scale, or in other words one which is not so difficult to make as to be beyond the reasonable cost of such a contrivance.
With these and other objectsy in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrange ment and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying 35 drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.
Two of the many possible embodiments of the invention are illustrated in the accompanying drawings, in whichz- Figure 1 is a front elevation, partly in section, of a chair constructed in accordance with the present invention; Fig. 2 is a top elevation thereof; and Fig. 3 is a front elevation, partly in section, of a portion of a modified construction.
Referring now first to Figs. 1 and 2 of the drawings, thenumeral 10 indicates a frame, including a horizontally extending plate member 11, supported by legs or standagainst the underface of a chair seat 16 andy attached thereto, for instance, by screws 17. The chair is provided with a back 18 and arm rests 19, which may be of any suitable conguration. In one of the arm rests and in the chair seat is journaled a ver` tically extending short shaft section 20, to which is keyed or otherwise attached, below the chair seat, in alignment with the sprocket wheel 13 a small sprocket wheel 21. A chain 22 runs over the sprocket wheels, imparting rotating motion to the seat when the sprocket wheel 21 is turned, as will hereinafter appear. To the shaft 20 is rigidly fastened above the respective arm rest a crank 20.
The operation of this device is as follows: The occupant of the chair rotates the shaft 20 by means of the crank 20. Inasmuch as the chain cannot move about the sprocket wheel 13, the chair seat, with the person thereon, is caused to move about the spindle 14 in a direction opposite to that in which the crank 20 is turned. The sprocket chain forms thus a connection between the two sprocket wheels, which causes the sprocket wheel 21 to assume a planetary movement relative to the fixed sprocket wheel 13. The speed of movement of the chair seat depends, obviously, on the speed at which the crank is turned. v
The modification illustrated in Fig. 3 of the drawings differs from the one above described in that the crank 20 thereof is disposed vertically on the side of one of the arm rests, it being xed to a spindle 23, carrying a bevel pinion 24, in mesh with a similar pinion 25, the latter being fixed to the shaft 20. The spindle 23 is suitably journaled in a bearing 26, fixed to the arm rest. Otherwise the construction and open ation of the elements are the same as of those described in connection with Figs. 1 and 2 of the drawings. Y
That I claim is 1. An amusement device comprising a base, a spindle rotatably mounted thereon, a chair seat fixed to said spindle, a sprocket Wheel attached toeaid base, seid spindle extending centrally through said sprocket whe'eLa shaft journaled on said seat,Y a
`sprocket wheel 'iigdly mounted V011 said 4 shaft, a chain running over said sprocket wheels,l and a crank for'turning'said shaft. 2. In an amusement device ceording to claim l, said sprocket wheels and chain being disposed between said base and said Qhain seat.
"Signed at New'York, inthe county of New York, and State of New York, this 3rd day of June, A. D. 1922 ROBERT* WENNERSTROM.
