JOHN FLINDALL, OF CHICAGO, ILLINOIS.

CHAIR.

Specification of Letters Patent.

Patented Nov. 19, 1907.

Application filed November 80, 1906. Serial No. 845,766.

To all whom it may concern:

Be it known that I, JOHN FLINDALL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Chairs and I do hereby declare the following to be a full, clear, and

- exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to furniture in general, and has for its object to provide an improved chair which is peculiarly constructed so as to hold the occupant either in an upright or in an inclined position as may be desired.

A furtherobject is to design a chair of this character which shall comprise few and sim ple parts of such a nature as to be readily adjusted to throw the various portions of the chair, into the desired relative positions.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings z-Figure 1 is a side elevation of a chair constructed in accordance with the invention, portions being broken away. Fig. 2 is a front elevation of the chair, portions being shown in section.

In the embodiment of the invention shown in the drawings, the numeral 1 designates the base which comprises the rockers 2 and the frame 3 supported by the legs 4. In the specific construction of the rockers 2 it will be observed that the forward ends thereof are flattened as indicated at 5 so that when the seat 6 is moved to its forward limit upon the frame 3 the chair will have a stable osition. The rear ends of the rockers 2 are also flattened as indicated at 7 so that when the seat is adjusted to the limit of its rearward motion the occupant can be held in a tilted position. Attention is also directed to the fact that the side pieces of the frame 3 extend rearwardly at S and are joined to the rockers 2, thereby forming braces which reinforce the rear ortions of the rockers. The seat 6 is slidiibly mounted upon the frame 3, and comprises the side pieces 9 and the transverse members 10. J ournaled between: the members 10 is a threaded shaft 11 which gasses through a bearing sleeve 12 carried ythe frame 3. WV1th this construction it will be readily apparent that by turning shaft 11 the seat 6 can be moved back and forth upon the frame 3. In order to facilitate this adjustment a transverse operating shaft 13 is j ournaled in one of the side pieces 9 of the seat and is provided at its innor end with a beveled gear 14 meshing with a similar ear 15 upon the threaded shaft 11.

A handIe 16 is carried by the outer end of the operating shaft 13 and by means of this handle motion can be transmitted to the threaded shaft 11 so as to move the seat back and forth to the desired position upon the frame 3. The chair arms 17 are also carried by the seat 6 and are supported by the upright members 18, the lower ends of which project slightly below the seat 6 and it upon opposite sides of the frame 3, thereby forming guide members to prevent any lateral movement of the seat with respect to the frame 3. The chair is also provided with a back 19, which is pivotally connected to the seat 6 and is held at any desired inclination by means of a transverse rod 20 which can be adjusted to the required position by engaging the ends thereof with the proper portions of the racks 21 carried by the arms 17. If found desirable, a footrest may be employed in connection with the chair, as indicated at 22, although the said footrest constitutes no part of the present invention and can be omitted if desired.

When the seat 6 is moved to its forward limit upon the frame 3 it Will be readily apparent that the chair will rest upon the flattened ends 5 at the forward portions of the rockers 2, and the occupant will be held in an upright position. On the other hand, when the seat 6 has been moved to its rearmost position the rockers will rest upon the flattened portions 7 and the occupant of the chair will be held in a tilted position. It will, of course, be understood that the rounded portions of the rockers intermediate the flattened ends are employed in the usual manner to obtain a rocking motion.

Having thus fully described my invention, what I claim new and desire to secure by Letters Patent is 1. In a chair, the combination of a base comprising a frame carried by rockers, the sides of the frame extending rearwardly into engagement with the rockers, and a seat slidably mounted upon the frame, the rearwardly extending portions of the sides of the frame serving the double function of forming braces for the rockers and a guideway upon'which the seat slides.

2. In a chair, the combination of a seat, a back pivoted to said seat, and a base, comprising a pair of rockers, flattened portions 0n the extremities of said rockers, standards on sand rockers, and side pleces mounted on said standards extending horizontally rear- Ward and secured to the flattened portions of said rockers. v

In testimony whereof I afliX my signature in presence of two Witnesses. JOHN FLINDALL.
