ROCKING-CHAIR.

SPECIFICATION forming part of Letters Patent No. 596,241, dated December 28, 1897.

Application filed August 11,1897. Serial No. 647,774. (No model.)

To all whom it may concern..-

Be it known that I, NELs H. HAssEL, a citizen of the United States, residing at Chicago,

in the county of Cook and State of Illinois,

have invented certain new and useful Improvem'ents in Rocking-Chairs, of which the following is a specification.

' This invention relates to improvements in sons and which may be easily set and kept in motion without the necessity of the operator placing his feet on the floor; second, a chair of the above-named character which shall be simple and inexpensive in construction, strong, durable, and satisfactory in operation, and, third, to provide an adjustable foot-rest which shall be so attached to the chair that it may be placed in a position to be out of the way when not in use and may be readily extended for use when desired.

In order to enable others skilled in the art to which my invention pertains to'make and use the same, I will now proceed to describe it, referring to the accompanying drawings,

in which-- Figure 1 is a view in side elevation of a chair embodying my invention. Fig. 2 is an enlarged plan view of the lower portion of the chair, taken on line 2 2 of Fig. 1, showing a part of the back and upholstered seat. Fig. 3 is a view of a portion of one of the supports for the foot-board and foot-rest, showing by dotted lines the position to which the latter may be placed when not in use. Fig. 4 is a View, partly in elevation and partly in section, of one of the improved screws and nuts therefor which I employ in securing the parts of my chair together; and Fig. 5 is a sectional view of one of the rocker-bearings of the chair.

Similar letters refer to like parts throughout the different views of the drawings.

chair rests.

A represents the pedestal or base upon which the chair rests, and is provided in its upper part and at each of its sides with a piece a, having a socket a to receive the projection b on the plate 13, which is secured by means of screws or otherwise to the lower portion of the sides 0 of the chair, thus forming rocker-bearings or pivot-points on which the The sides 0 of the chair are secured together by means of tie-rods c and are provided with an upholstered or other suitable seat 0 and with the back 0 and armrests C of any suitable material and designs.

Secured to the rear portion of the pedestal A at one of their ends and between the side pieces 0 are springs D, which are bowed inwardly, as shown in Fig. 1 of the drawings, and have their other or upper ends secured to the rear portion of the chair. Extending from therear portion of the chair-seat to near the front portion thereof are semicircular rods or bars E, which are located near the side pieces 0 and are rigidly secured to the lower portion of the chair-seat. Pivotally secured at one of their ends to the sides of the base A are bent rods or bars F, which support the foot-board G and the arms 9 of the foot-rest G, which extends crosswise in front of the chair, as is shown in the drawings. The rods'or bars F are supported on the bottom of the chair-seat, near its front portion, by means of springs e, which are secured at one of their ends to said rods and at their other ends to the chair, as is clearly shown by dotted lines in Fig. 1 of the drawings. Each of the rods or bars F is formed or provided near its free end with a hooked lug h or h to receive the curved arms g, which support the foot-rest G and allow the same to be extended or retracted. The arms g are provided with lugs or enlargements g to engage the hooked lugs h on the rods F- when the said arms are in their extended positions, thus sustaining the foot-rest G at the desired point. Extending from one side of the base A to the other and in the front portion thereof is a rod 0, on which and near the ends of said rod are fulcrumed bell-crank levers H, the free ends of which extend forwardly and beneath the foot-board G and the other ends of which are pivotally connected to the rods i, which are rigidly secured at their other ends to the bent rods or bars E, which, as before stated, are located beneath the seat portion of the chair and between the sides of the base or pedestal.

The upper ends of the arms g are usually provided with flanges 9 on which rests and is secured by means of screws and nuts m and m the foot-rest G, which is preferably made'of soft material.

While I may use any suitable securing devices for fastening the foot-rest on the arm g, yet I prefer to use screws and nuts of the construction illustrated in Fig. 4 of the drawings, which consists of a shank m, having a portion thereof reduced and screw-threaded, as at m and formed with a shoulder m against which the socketed screw-threaded nut m rests. The socket or opening in the nut m is of a greater depth than the reduced portion m of the shank, thus allowing the inner end of the nut to contact with the shoulder m of the screw-shank, and prevents the heads at and n of the nut and shank, respectively, being drawn too closely together, so as to be em. bedded or wearing into the wood or other soft material which the screw and nut is designed to secure together.

The operation of my chair is simple and as follows: By pressing on the foot-board G with the feet the chair will be rocked until the footboard contacts with the bell-crank levers H, which will depress their outer ends and raise their other ends, thus drawing the rods or bars E forwardly, which operation will depress the springs D, when by removing the pressure of the feet from the foot-board G the springs D will force the rear portion of the chair-seat upwardly, thus causing the chair to turn or rock on its bearings, when the abovedescribed operation may be repeated and the chair kept in a rocking movement.

Having thus fully described myinvention,

cured to the pedestal and to the chair, the

rods E, secured to the front and rear portion of the chair, the bell-crank levers II, fulcrumed on the pedestal and connected to the rods or bars E, and the supporting-bars F, pivotally secured at one of their ends to the pedestal and having their other ends outwardly extended over the bell-crank levers, and the foot-board G, secured on the supports F, substantially as described.

2. The combination of the pedestal A, having sockets or bearings in its sides, of a chair having on its lower portion projections to operate in said sockets or bearings, the springs D, secured to the rear portion of the pedestal and the rear part of the chair, the circular rods or bars E, secured to the lower part of the chair at its front and rear, the bell-crank levers H, fulcruined on the front part of the pedestal and connected to the rods or bars E, the supporting-bars F, pivotally secured at one of their ends to the pedestal and having their other ends extended forwardly, the foot board G, secured on the forward ends of the bars F, and located above the outer ends of the bell-crank levers, and the arms g, provided with the foot-rest G, and adjustably secured to the bars F, substantially as described.

NELS II. I'IASSEL.
