WALLEN DANIELS, OF FORT SMITH, ARKANSAS.

CHAIR.

SPECIFICATION forming part of Letters Patent No. 530,092, dated December 4, 1894. Application filed August 19, 1893. Serial No. 483,541- (No model.)

To all whom, it may concern:

Be it known that I, WALLEN DANIELS, a citizen of the United States, residing at Fort Smith, in the county of Sebastian and State of Arkansas, have invented a new and useful Chair, of which the following is a specification.

My invention relates to improvements in reclining chairs; and the objects in view are to provide a chair of cheap and simple construction that may be conveniently disposed in various positions to suit the occupant and render him comfortable.

With these and various other objects in view the invention consists in certain features of construction hereinafter specified and particularly pointed out in the claims.

Referring to the drawingsz-Figure l is a side elevation of ay chair constructed in accordance with my invention, the same being in its ordinary position. Fig. 2 is a front elevation thereof. Fig. 3 isa side elevation, the chair being extended to serve as a couch or bed. Fig. 4 is,a detail in perspective of the head-rest. Fig. 5 is a sectional view of the foot-rest. Fig. 6 is a horizontal sectional view of Fig. 1 above the ratchet and opposite` pawls and through the side-bar of the chair.

Fig. 7 is a transverse sectional view through the spur-gear at one end of the foot-rest and its guide.

Like numerals of reference indicate like parts in all the figures of the drawings.

Supported upon suitable standards 1 are the opposite frame-bars 2 composing the seat section 3. From the bars 2 rise the arms 4, which are of the usual construction.

To the rear ends of the bars 2 the side bars 5 of the back-section 6 are pivoted as at 7, and said bars 5 are provided near their upper ends with pairs of front and

rear slots

8 and 9 respectively.

To the opposite sides of the bars 5 sliding plates 10 are applied, the -same being provided at their upper and lower ends and at their -inner edges with stops or shoulders 1l. Bolts 12 pass through the plates 10 into the slots 9 and serve to retain the plates in position. To the upper bolts 12 of these plates arms 13 are pivoted, and the same terminate at their outer ends in bearings 14, which receive the journal 15 upon which is mounted VYtherevoluble head-rest 16 which is designed to move over the upper rounded ends 17 of the bars 5. A iiat spring 18 is secured to the upper stop 11 of each of the plates 10 and rests upon the edges of the arms 13, thus retaining the revoluble head rest 16 upon the curved edges ofthe said bars 5.

Pivoted as at 19 to the front ends of the seat bars 2 are the suspension bars 20, and the same carry upholstering 2l thereinbetween. The bars 2O are provided with inner and outer slots 22 and 23 respectively. In the slots 22 of the bars 2O and the slots 8 of the bars 5 sliding blocks 24 are located,` and pivoted to these blocks as at 25 are opposite connecting rods 26, which at their intermediate portions are pivotally connected to the bars 2 by studs 27. The bars have secured upon their inner faces oppositely toothed ratchet wheels 28, and pivoted gravity pawls 29 are secured to the opposite sides of the seat frame and engage therewith.

Hinged as at 30 to the lower ends of the bars 2O are the extension bars 31, and the same are pivotally connected as at 32 to the inclined bars 33 whose upper ends have pins 34 extending from their outer faces and mounted for movement in the slots 23. The inclined bars 33 are slotted between their ends as at 35, and attheir inner sides are provided with rack-bars 36.

37 designates the foot rest, and the same is provided at its ends with depending portions 37? through which extend fixed pins 33, that move in the slots and with a transverse shaft 39, having anti-friction rollers 40 at its ends that extend into the slots 35 and at the inner sides of which cog-wheels 41 are located, the latter lnoving in grooves formed in the vrrack-bars 36. Coiled springs 42 are located upon the pins and interposed between the depending ends of the foot-rest and loose washers 38", of the pins'are curved latches 43 that are so iniiuenced by Lthe springs that their outer` ends are normally in engagement with the cog-wheels, whereby the latter are locked against rotation in the rack-bars 36. The latches are pivoted in position upon shafts 44 having knobs 45 by which they are operated to disengage the latch and permit of an adjustment of the foot-rest. This completes the construction of the chair.

and pivoted to the inner endsV W'hen the chair is in the position shown in Fig. 1 it will be seen that the upper blocks 24 abutagainst the upper shoulder 1l and the plates 10 have been moved upward in the slots 9, and the springs 1S pressing the arms 13 backward have caused the head-rest to roll over the upper rounded ends of the bars 5 of the back until said head-rest is substantially in line with the back.

It will be seen that the chair is locked against any displacement by the pawls 29 engaging the ratchet wheels 28. The footrest is adjusted in the manner heretofore stated, and it will be seen that the same may be drawn out to any extent desired, such operation being secured by moving the footrest up or down in the inclined bars 33, the latter being given any desired inclination, and at their lower ends resting upon the floor.

Of course the back may be adjusted at any angle, the pawls 29 being temporarily disconnected from their ratchet wheels to permit of such adjustment. Again it will be seen, as shown in Fig. 3, the chair may be arranged in a horizontal position to serve as a bed or couch, the back-section, seat-section, foot and intermediate sections all being in a horizontal plane. V'Vhen bringing the parts to this position the blocks 24 moving down the slots 8 come in contact with the lower shoulders ll of the plates l0, so that these plates are drawn inward and the head-rest made to rotate down the rounded ends of the bars 5 of the back section, so that the said rest lies across said section in the manner shown in Fig. 3 and serves as a pillow therefor. Thus, it will be seen, that the foot and back sections and the head-rest are adjusted simultaneously and proportionately by the adjustment of the side-bars, which are within reach 'of the occupant of the chair, and that when said side-bars are locked, the said foot and back sections and the head-rest are secured in their adjusted positions.

From the foregoing description, in connection with the accompanying drawings, it will be seen that I have provided a very simple construction of chair that may be securely locked in a convenient manner in any desired position and adapted to serve as an ordinary chair, a reclining chair, or as a couch 0r bed.

I do not limit my invention to the exact details of construction herein shown and de scribed, but hold that I may vary the same to any extent and degree within the knowledgeof the skilled mechanic.

Having described my invention, what I claim is l. The combination with a stationary seat section and foot and back sections hinged respectively to the front and rear edges of the seat sections, of side bars pivotally mounted at intermediate points upon the sides of the seat section and slidably connected at their extremities respectively to the back and foot sections, means for locking said side bars at the desired inclination, plates slidably mounted upon the sides of the back section adjacent to its upper edge, arms pivotally connected to said plates, a headrest journaled in the outer extremitiesof said arms, and connections between the sliding plates and the upper ends of the side-bars, whereby the foot and back sections and the head-rest are adjustable simultaneously and proportionately by the adjustment of the side bars, substantially as specified.
