CONVERTIBLE CHAIR.

SPECIFICATION forming part of Letters Patent No. 399,069, dated March 5, 1889.

Application filed January 11, 1888. Serial No. 260,460. (No model.)

To a]! who/2t it may concern.-

lle it known that I, BENJAMIN (T. ODELL, of Kingston, in the county of Ulster and State of New York, have invented a new and useful Improvement in Convertible Chairs; and I do hereby declare that the following is afull, clear, and exact description of the same.

My invention relates to convertible chairs, and is an improvement upon the chairs shown in the Letters Patent of the United States granted to me on the 5th day of May, 1885, No. 317,001.

My object in the present invention is to eheapen the construction of the aforesaid chair, and to render it more compact without reducing the height.

The chair is shown in the accompanying drawings, in which Figure 1 represents the chair in perspective in raised position. Fig. 2 shows the same view of the chair lowered to form a carriztge.

In the drawings, the legs a 7) are crossed legs, pivoted to each other at .l, and one of these legs, (I, is pivoted to the frame of the clniir-body. The other is connected to the body, preferably by a link, 0; but this may be omitted, as the parts are held by the lock of the other parts. lleretofore these legs have been pivoted directly to the chair-bottom. This renders long legs necessary, and these, when spread to reduce the chair to the form of a carriage, render the length of the carria excessive, while the seat was correspondingly low. To obviate this the chair-seat A is made to rest on legs (I, which are supported on sills e. The posts and sills form a frame on which the chair-seat rests. The legs a and i; are in pairs, connected by suitable rounds, and the chair has a straight back, I), fixed to the frame and bottom of the chair and forming part thereof. The wheels ff and g g are pivoted near the lower ends of the legs, so as to be on the floor when the chair is down and to be raised clear when the chair is up; or the front wheels, f, may be arranged. to bear on the floor at all times for convenience in moving. 1 To the lower ends of the legs, either front l or rcanl pivot the locking or push arms E, which are connected to each other by suitable rounds and to the chair-back at some. suitable point by links 71. The adjustment is shown in Fig. 2, in which the arms E, which serve in other positions to lock the structure in a raised position, serve here also as pusharms. To raise the chair, the operator holds down the arms an (l raises the chair more easily by lifting from the back. When the chair has been raised, to extend the links in line with the arms E the latter are swung in toward the chair-back, past the line of the pivots of the lower ends of E and upper ends of 72. This locks the arms, and the whole structure is thereby locked and held securely in place.

As shown, the arms E are pivoted to the rear legs, which is the required position when the arms are to be used as pushcrs as well as locking-arms. In shifting these arms from rear to front the links may also be shifted from the front to the rear edge of the frame. The chair as above described is more stable, as well as more compact, and, while inexpensive, is apopnlar form of chair, as it is of very neat appearance.

The legs may be turned up to form rockers more conveniently with this form of chair, as the legs are of convenient length therefor. In this case the wheels are pivoted at the turned-up ends, so as to be clear of the door.

I claim as my invention- A convertible chair consisting of the seat, a supplemental frame beneath the same, serving to support the seat and form a base therefor, pivoted crossed connected with the lower sills of the frame to support the same, the wheels connected to the legs, and the pivoted arms E, and the locking-links connecting the arms tothe chair, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
