I 'swIvEL cnam.

Application filed September 8, .1922. Serial No. 586,903.

I more particularly to a chair of this character which is suitable for musicians having to use several instruments. Such chairs are particularly useful for so-called trap drummers; that is to say, a musician who has to beat small and large drums as well as kettle drums arranged around him. With the ordinary chair, it is, very diffi cult for such a musician to reach any of the drums except those nearest to him and the object of the present invention is to furnish a chair on which the musician can not only turn around but also travel sideways when seated upon the chair and, in this manner, be able to easily handle drums even at some distance from his central position. In the accompanying drawings one embodiment of the invention has been illustrated, and:

Figure 1 is a perspective view of my improved chair,

Figure 2 is a top plan view of the chair with the seatremoved,

Figure 3 is a vertical central sectional view through the chair, and

Figure 4 is a horizontal section along line 4-4 of Figure 3.

The chair includes a base or pedestal 10 provided with an upright socket 11 adapted to engage a pintle 12 extending downwardly into the socket from a main arm 13. Between the underside of the arm 13 'and the top face of the socket 11 is preferably inserted a ball bearing 14 and inserted in the socket around the pintle 12 is a roller bearing 15 in order'to-insure the easy turning of the arm 13 in the socket. The lower end of the pintle 12 is threaded to receive a lock nut 16 and a washer 17 engaged against a shoulder on the pedestal whereby to prevent axial displacement of the pintle in the socket. Normally, the arm 13 extends in a rearward direction from the socket and carries at its rear end a second socket 18 similarly provided with a ball bearing, 19 and a roller bearing 20. In this. socket is disposed a pivot 21 extending downwardly from the rear end of an intermediary arm 22 and secured in a manner similar to the pintle 12 by means of a nut 23 and washer 24.

The forward end of the intermediary arm 22 is also provided witha socket 25 likewise preferably having a ballbearing26 and a roller bearing 27 similar to those already described. f

The seat 28 has a back rest 29 and, as shown in Figure 3, may be furnished with a suitable covering 30. Near the forward end ofthe seat a short pivot 31 extends I into the socket 25 engaging the ball bearing 26 and roller bearing 27,. This pivot is secured by means of a washer 32 and nut 33. A staple 34 is preferably provided. at the end of the threaded portion of the 'pivot 31 and said stapleis adapted to receive a hook 35 on a-- chain 36 secured, as at 37, to the forward end of the lower arm 13. The chain and hook are intended to limit the movement", between the two arms, but by detaching "the hook 35'from seated in the chair will be enabled to turn partly around by turning the seat in the socket 25 and he will also be able to turn around in the chair on the central pintle 12. If a sidewise movement in either direction of the pedestal is desired, he can travel sidewise with the aid of his feet, without turning around and at the same time face in one direction all the time, when the pintle as well as the two pivots will turn in their respective sockets, such sidewise movement, however, being limited by the length of the chain 36. I

It will accordingly be clear that a musician using the chair in the manner set forth, will not be hampered by being can fined to one position, in which case he would have to stretch his arms and body to one side or the other in order to reach the furthermost positioned instruments. In

using this chair, however, he can push himself, by means of his feet, when the chair will permit him to travel in a straight line or in a curve, as required, on both sides of.

of the chair are extended full length to one side or the other supporting the musician.

Having thus described the invention, what is claimed as new is:

1. The combination of a relatively stationary pedestal, a jointed support pivotally mounted on the pedestal with its joint normally at the rear of the pedestal and its free end normally in front of the pedestal, and a seat having a pivot on its under side near its front edge engaged in the free end of thejointed support.

2. The combination of a relatively stationary pedestal, a, jointed support pivotally mounted on the pedestal with its joint free end of the jointed support, and means extending between the pedestal and the free end of the support to limit lateral movement of the support.

3. The combination of a stationary ped estal, an arm pivoted at one end on the pedestal and normally vextending rearwardly therefrom, a second arm pivoted to the rear end of the first-mentioned arm and normally extending over the same and across the upper end of the pedestal, a seat, and a pivotal connection between the seat and the free end of the second-mentioned arm, said connection being disposed between the center of the, seat and the front edge of the same.

'In testimony whereof I aflix my signa tare.
