UNITED .STATES NATHANIEL B'. HARMON, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TO PA-TENT orion.

CLAUDE M. HART, OF OSTON, MASSACHUSETTS.

CHAlR.

SPECIFICATION formingpart of Letters Patent No. 665,005, dated January 1, 1901. Application led February 23, 1900. Serial No. 6,168. (No model.)

To all whom it may concern:

Be it known that I, NATHANIEL B. HARMON,

.of New York, borough of Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Chairs, f -of which the following is a full,clear, and exact and in the various details to which I shall refer. It is shown as applied to a rocking-chair, to which it is particularly adapted; but I do not intend to confine myself to any form of chair.

In the accompanying drawings, Figure 1 shows in perspective a chair embodying my invention. Fig. 2 is a central longitudinal section of Fig. 1. Fig. 3 corresponds to Fig. 2, with the side supports of the chair partly in section. Fig. 4 isfa section upon the line 4 4 of Fig. 3. Fig. 5 is -a section upon the line 5 5 of Fig. 3. Fig. 6'is a section uponV the line `6 6 of Fig. 3. Fig. 7 shows an alternative form of adjusting and supporting mechanism for the foot-rest. I

1 1 represent the feet of a chair, upon which are mounted therockers 2 2, which may be maintained in normal position by springs 3 3. Upon the rockers 2 2 is supported the frame or body of the chair proper,.which comprises the sides 4 4, the back 5,' and the interconnected portions, which I shall describe hereinafter. The sides 4 4 are mounted upon supports or guides 6 6, which are journaled upon roller or ball bearings, (see dotted lines 7,) so that the chair-frame can be moved forward and backward upon the rockers 2, motion being imparted by a wheel S,v conveniently mounted upon a shaft 9, which carries at either end a pinion 10, which travels'upon a rack 11, or by other suitable means. The ob.- ject of this adju'stability of the chair-frame upon the rockers is to secure a proper balance of the chair when the adjustment of the other parts disturbs it. v

In order to lock the chair-body firmly in any desired position upon the rockers 2', I provide a rod 22, which extends from the upper face of the side support or guide 6 into a-slot'in the rocker 2. The upper end of rod 22 is attached-to a rod 19, which is so attached to a cam-headed lever 20 that when the latter is depressed the rod 19 is pushed down and its head 24, which is in the slot 23, is pressed away from the upper side of slot 23. This ac tion releases thesupport 6 from engagement with vrocker 2-that is, unlocks them-and the opposite motion of llever 2O draws the head 24 tightly against the upper side of slot 23,

thus locking parts 6 and 2 tightly together. It is preferred, although not essential, to have a corresponding locking arrangement on the otherside of thechair and to have them connected by rod 19, so as to be operated 'together.

At' the front of the chair I provide a footrest 25, lwhich may be extended, as shown in Figs. 1, 2, and 3, dottedlines, or folded or .pushed back under thebody of the chair, as

shown in the full lines, Fig. 3. This foot-rest 25 has at each side of its rear end a short fiat rod 26, arranged at an angle to the length of the foot-rest. These rods 26 fit in circular sockets 27, in which they move freely. Each of these sockets 27 is provided with an oblique entering-channel 28, so disposed that when the foot-rest 25 is raised to any required angie-as,l for example, that shown inthe dotted lines of Fig. 3-the rod 27 may slide out, thereby permitting the foot-rest to he pushed back and folded away, as shown in Fig. 3. In order that the foot-rest may-be conveniently adjusted at a desired angle, I provide at one side of the chair alever29, Fig. l4, fast upon a rod 30, which is rotatably mounted in the sides 6 6 of the chair, preferably 'near its front. Near each end this rod carries a pawl 31. The rod 30 is under the stress of a spring lor springs 3.2, lfastemed to theside bars 6 6, which tend to rotate it,and with itthe pawls 31, into the position shown in Figs. 3 and 4-that is, with IOO chair.

The foot-rest 25 is provided near its rear end with toothed racks or segments arranged to be in position for engagement by the pawls 3l when the f`oot-rcst is drawn out, as shown in Figs. l and 2. I/Vhen it is so drawn out, lever 2), Fig. 4, is rotated until the pawls 3l engage with the teeth of4 segment 33, thus holding the foot-rest at any desired angle.

'If the foot-rest be raised to, say, the height shown in dotted lines in Fig. 3, pawls 3l are released from the rack-bar 33 and the springs 32 will rotate rod 30, so as to throw back pawls 3l to the position shown in Figs. 3 and 4, out of the line of movement of foot-rest 25 when it is folded away, thus permitting the rods 26 to be withdrawn from sockets 27, so that the foot1'est 25 may. be folded back under the chair-body.Y

In Fig. 8 I have shown an alternative form of adjusting and holding device for the footrestw In this case the rods 26, which are round, are mounted upon a spring-catch 34, which is retracted by a finger 35 upon the rod or lever 36. As here shown, the rack or segment 33 is convex instead of concave,as before, and the pawl is curved to contact properly with it. The operation of this modifiedform will, I believe, be readily understood.

I provide a hook or latch 37, Fig. 3, upon the rear half of one or both of the rockers 2,

and a series of catches or notches 38 on the base l to secure the chair in position, if desired, when it is rocked back. A flat curved spring 39 upon the rocker will serve to keep hook 37 in either position and prevent it from swinging.

For the sake of convenience and beauty I arrange as many as possible of the devices which I have described under the body of the chair and inside of the rockers.

From the foregoing it will be understood that there are several adjustments possible in the chair provided for by my invention.

First. The adjustment of the foot-rest 25. This is accomplished by pulling foot-rest 25 from its folded position beneath the body of the chair, Fig. 3, elevatingits front end until the rods .26 will slide up slots 28 to sockets 27, then lowering the front end to the desired position, and at the same time rotating pawls 3l (by means of lever 29 and rod 30) until they engage with the rack 33, or this may be done by the alternative devices shown in Fig. 8.

Second. The adjustment of the main body of the chaiflongitudinally upon the rockers 2.. This is chiefly necessary to' restore the proper balance of the chair-body after adjusting the foot-rest or for other reasons. It is accomplished by depressing lever 20, so as to unlock guides 6 'from rockers 2, (by depressing the headed rod 22 in slot 23 through the rotation of cam 21.) Then the wheel Sis rotated, causing pinions 10, which carry the chair-b ody, to travel over racks l1 upon the rockers 2 until the required relative positions of the two are reached. Then lever 2O is thrown back again to relock the parts.

Third. If it is desired to rock the chairbody back and hold it there, this may be done by hooking the hook or latch 37 into one of the notches 33.

The drawings show an adjustable chairbaok 5 of peculiar arrangement or construction. While I do not make any claim to this improvement here, I do not abandon it, but make it the subject of a separate application for Letters Patent. 'A

It will be seen that the chainframe which I show is entirely bare of upholstery and is typical orconventional in form. These are of course matters of no consequence, this simple form being adopted to show clearly my invention.

It will occur to any one that the devices and arrangements which I show and describe may be varied Widely without going beyond the scope of my inventionid that many of them may beapplied to chairs other than rockingchairs.
