CHAIR.

Specification of Letters Patent.

Patented May 18, 1909.

Application filed April 1, 1908. Serial No. 424,616.

To all whom it may concern:

Be it known that I, JOHN SMITH, a citizen of the United States, residing at the town of Bingham Canyon, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Chairs, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in rocking chairs, and particularly to peculiarlyconstructed means for adjusting the seat and back of a chair, preferably, a rocking chair. I

The object of the invention is the provision of means for facilitating the adjusting of the seat and. back of a chair.

Another object of the invention is the peculiar construction of a rocking chair, the seat and back of which can be quickly adjusted for accommodating a tall or short person, by means of a manually-operated device carried by the frame of the chair and cooperating with the seat for raising and lowering the same.

A further object of the invention is the peculiar construction of a rocking chair providel with means for adjusting the seat thereof, and which chair comprises a minimum number of parts, is etliicient in operation, and comparatively simple to construct or manufacture.

With these and other objects in view, the invention consists of certain novel con-- struotions, combinations, and arrangements of parts, as will be hereinafter fully de scribed and claimed.

in the drawings: Figure 1 is a view, in side elevation, of a rocking chair constructed in accordance with the present invention. Fig. 2 is an inverted plan view of the chair depicted in Fig. 1. Fig. 3 is a vertical, longitudinal sectional view of the chair depicted in Fig. 1. Fig. 4 is a transverse, sectional view taken on line 4, 4, Fig. 3. Fig. 5

is a perspective view of the filler-frame.

Fig. 6 is a view in side elevation of one of the cam-members. Fig. 7 is a perspective view of one of the guide brackets. Fig. 8 is a perspective view of one of the bracket plates.

Referring to the drawings by numerals, 1 designates the rockers, to which are secured outwardly-curved legs 2; each leg is provided with a lower, bifurcated end surrounding portions of a rocker, as at 3. The

bifurcated, lower end of each leg is fixedly secured, by any suitable fastening means, to a rocker. By reason of the bifurcating of the lower end of each leg 2, a very durable structure is produced.

" The frame of the chair comprises front and rear ends 4 and 5, respectively, and sides 6. The movable seat 7 is provided with a back 8, and with arms 9.

The front end 4 of the frame is notched or cut-out as at 10, and extending across this notched or cut-out portion is a horizontal pin 11, below which is positioned a guide-member 12. The guide-member 12 is, preferably, formed from a single piece of wire or material, and is bent downwardly, at its front end, and is slidably positioned between said pin 11 and the bottom of the cut-out portion 10, so that when the seat 7 is slid forward and backward upon the frame, the guide-member 12 will slide in the out-out portion 10 and will be prevented from accidental displacement by means of pin 11. The guide member 12 is bent intermediate its ends, and is provided with a rear portion 13, which is secured, by any suitable fastening means, as for instance, screws 14, to the bottom of the seat 7.

Formed in the bottom and contiguous to the sides are longitudinally extending grooves 15, in which is normally positioned the upper edges of the sides 16 of the fillerframe 17. The frame 17 constitutes a continuation of the frame secured to the legs, as said seat is adjusted, for said filler-frame 17 is raised and lowered synchronously with the seat 8. Secured at the rear end of the sides 16 is back 18 of the movable frame 17, which back is provided with a notched or cut-out portion, as at 19, having a staple 20 positioned therein. A staple 21, Fig. 3, straddles the staple 20, and said staple 21. is secured to the seat. The staples 20 and 21 con stitute fastenin means for movably connecting the rear end of the filler-frame to the seat, so that when said seat is raised or lowered, the filler or auxiliary frame will be also raised and lowered. Each side 16 is beveled, as at 22, whereby the sides conform to the contour of the under face of the seat or of the groove 15, which curves according to the curvature of the seat. Each side 16 is provided, near its front end, with a curved, elongated slot 23, through which extends a fastening means, as for instance, a nail 24, for slidably connecting the front ends of frame l 17 to the sides of the primary frame carried which would otherwise be involved when the seat is raised off of the supporting or primary frame 5. i

'The seat is raised or lowered upon the primary or supporting frame, through the medium of spring cam-members 25, fiXedlv secured to a rotatable shaft 26. I preferably,

form said cam-members from a coiled piece of strong wire, and secure the inner end of the wire in a fixed position to shaft 26. The shaft 26 is journaled, at one end, in a bracket-plate 27, which plate 27 is secured,

. sides and terminates at its outer end in a by any suitable fastening means, to the inner r face of one of the sides, and the shaft extends through another bracketplate 27, near its other end and also through one of the knob or grip 28, which can be quickly engaged by the operator for rotating said shaft 26 and imparting rotary movement to the spring cams, for the purpose hereinafter specified.

A pair of guide-brackets 29 is secured to the bottom of the seat 7, by any suitable fastening means, and each bracket comprises a horizontal base 30, and a rearwardly-extending, inclined side portion 31 which is bifurcated, as at 32, Fig. 7, at its lower end for straddling the shaft 26; contiguous to the inner end of the bifurcated portion 32 of each bracket 29, is a horizontally-extending lug or projection 33, which is fixedly secured, at its inner end, to the outer face of the bracket, and each lug or pin 33 extends through a portion of the spring cam member 25.

It is to be noted that I have provided a peculiarly-constructed cam, or cams, carried by a rotatable shaft, which cooperate with peculiarly-constructed means secured to the bottom of an adjustable seat for raising or lowering the seat, as the shaft is rotated. Furthermore, it must be borne in mind that owing to the inclined bodies 31 of the brackets 29 and the inclined walls of the bifurcated portions, as the cams raise the seat, the same ..is guided or pushed forward for placing the seat in more of an inclined position than its normal posltion, Fig. 1, for accommodatmg a person with short legs. This vertical and sliding, forward movement is accomplished by my peculiarly-constructed device, and the same is also guided in this movement by I have found, b 7 actual expe and-l we d;

time, the filler or auxiliary frame 17 will slide down into position as shown in Fig. 1.

I have constructed a rocking chanpro. videdwith comparatively long rockers for permitting a person to rockfreely without danger of being upset, and I have also pro duced a very durable structure by the for-- wardly-curved or extending feet carrying the supporting-frame.

Furthermore, it is to'be understood that by my peculiar means, here inbefore described, the seat can be slid forwardly for throwing the front end downwardnear the floor or support carrying the chair, and at the same tlme, the rear end of the seat will be raised and, when it is desired to lower the seat, the same can be" quickly done by placing the seat back in its normal position.

and back supported upon the frame of a rocker, still I do not limit myself necessarily to a chair'having rockers, form some cases,

while I have, preferably, shown the seat it might be desirable to em loy the raising] and lowering means on a c iair having legs:

111 engagement direct with the floorfand, therefore, I do not limit'myself to arocking chair, but claim that my invention is clearly ada )ted to an ordinary chair only provided with legs, or a chair, the legs of which are attached to rockers. I
