DAVID BUZZELL, OF CHARLESTOVN, MASSACHUSETTS.

BOOKING-CHAIR.

Specification of Letters Patent No. 22,486, dated January 4, 1859i.

To all whom tt `may concern:

Be it known that I, DAVID BUZZELL, of Charlestown, in the coun-ty ofll/liddlesex and State of Massachusetts, have invented an Improved Recumbent Rocking-Chair; and do hereby declare that the same is fully described and represented in the following specification and the accompanying draw* ings, of which- Figure l, is a top view ot said chair as it appears preparatory to its being upholstered, the back being thrown down into an inclined position. Fig. 2, is a side elevation oiE the same the chair under such circumstances being exhibit-ed as supported on the floor by means of its caster or toot levers. Fig. 3, is a side view fot it as it appears when supported on its rockers, Fig. 4, is a longitudinal and central section ot it when its parts are in position as shown in Fig. 3. Fig. 5, represents a longitudinal section of it with its bach elevated and its leg .rest brought into a vertical or nearly vert-ical position.

rThe chair .with which my invention or improvements are represented is such as was patented by me on the 31st day of August, 1858, and represented in United States Patent No. 21,320.

In the above mentioned drawings, the seat frame of the chair is exhibited at A, as constructed of two leg portions, a, a, (each of which has two legs, o, 5,) connected by bars, c, c, and in manner to receive and support the arm rests, d, (Z, which are stationary relatively to the back B., the seat C., and the leg rest, D. The said back, seat, and leg rest are connected together and applied to the seat frame A, and operated by mechanism all substantially as described in my said patent, in order that while the back is being turned downward into an inclined or recumbent position, the leg rest may be turned upward and on its journals or supports, the positions of the said parts under such circumstances being as shown in Figsl and 2, of the accompanying drawings.

To the leg rest D, or levers, e, e, (making part of the same,) I apply an extension toot rest frame E, carrying a foot rest, F., which may be so applied to the said frame E, as either to be stationary relatively to it, or be capable of being turned or folded up or down in the ordinary way.

The frame E of the foot rest is iitted to the leg rest levers in such manner as to be able to slide between them, either toward or away from the seat, the upper part of the said foot rest traine being hinged or jointed to two levers G, G, turning on fulcra f, f, extended from the inner -sides of the levers, e, e, respectively. The longer arms of the said levers Gr, G, pass respectively through staples g, g, (or their equivalents) applied to the front cross bar of the .seat frame, the same being shown in the drawings. lVhile the leg rest is being elevated, the said levers rGr, G, acting in the staples, g, g, will be moved on their fulcra so as to move the toot rest in a direction away from the seat and thus extend it in order to accommodate the said foot rest to the position of the feet of a per-son 'as his legs are drawn up or moved toward a horizontal position. As the movements of the leg rest are controlled by those of the bac-lt, it will be readily seen, that while the back is being moved forward from a recumbent to a vertical position, the leg rest will be depressed, and the toot rest be brought nearer to the seat.

A foot or caster lever, H, is jointed to each leg of the seat frame so as to be capable of turning in a vertical plane, on a fulcrum, 7i, such levers being arranged as shown in the drawings. At or near the outer end of each ot the said levers, either a caster or a foot, i, may be affixed. Furthermore, a rocker, l, is applied to each pair of toot levers, on each side of the chair, that is to say, the said rocker, near its front end turns on a pin or screw it', extending through it and being screwed into the front foot lever. Besides this, a similar pin or screw, Z, extends through a slot, m, formed in the rocker as shown in Fig. l, the said screw being screwed into the rear foot lever. Furthermore, there is placed between each pair of foot levers and its rocker, a lifter lever, K, which is formed as shown in side view in Fig. 6. At or near its front end the said lifter turns on a pin or fulcrum, a, extended from the rocker. The rear end ot each of the said lifter levers is jointed to the lower toggle, L, of a pair of toggles, L, M., there being two pairs of such toggles, and each pair having its upper toggle, M, jointed tovv the seatframe so as to be capable otl swinging in a vertical plane. The two sets of toggles are connected together by a handle shaft, 0, which extends :trom the joint of one pair to that of the other. Furthermore, at or near the middle of each lifter lever or t0 a projection, p, therefrom, a connection bar or link 7, is jointed so as to be capable of swinging in a vertical plane. The lower end of the said connection bar is jointed to the rear arm of the front foot lever at 2f. Another conneetion bar, u, ointed at one end to the inner arm of the rearmost foot lever is also jointed at its other end to the'middle part of the connection link, r.

Then the handle shaft, o, is in its lowest position, as shown in Fig. 4, the chair will be supported by its rockers resting on the floor, but if the handle shaft be moved upward into its highest position the chair will be supported by its foot levers, whose feet will then be on the ground or ioor underneath it. Therefore, by means of the two rockers and their two sets of foot levers arranged together and connected by lifting levers or mechanism as specified, or any equivalent therefor, the chair may be converted from a stationary reeumbent, to a rocking recumbent chair, or vice versa, at pleasure.

I do not claim an extension foot rest or one so applied to a chair as to be capL ble of being moved toward or away from the `,seat of the chair, and whether such foot rest be sustained by cords and weights or not, as such a foot rest 1s very old and has been 1n use many years. Nor do I claim a chair constructed as shown in the United States' Patent, No. 19,352, but

I claiml. In combination with the chair stand or frame, the movable leg rest and the sliding foot applied to such leg rest essentially7 as described, a mechanism, by which, when the leg rest is moved or swung upon its fulcra or bearings, the sliding foot rest shall be moved onl its supports, either toward or away from the seat substantially as specified.

2. I also claim the combination of the foot levers and the rockers applied to the chair o-r seat frame, and so as to operate together substantially as described.

3. I also claim the combination of the toggles, the lifting levers and their connections with the foot levers and rockers the same being for the purpose of so operating the said rockers and levers as to cause the chair to be supported on the ground 0r floor, either by the two rockers or the four foot levers as set forth.

4. I also claim so combining a foot rest with a movable or turning leg rest, that the former shall be movable relatively to the latter as specified.

In testimony whereof I have hereunto set my signature.

DAVID BUZZELL.
