ROCKlNG-CHAI R.

SPECIFICATION forming part of Letters Patent No. 247,656, dated September 27, 1881.

Application filed February 2, 1881. (No model.)

To all whom it may concern:

Be it known that I, EDWARD KETTLER, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Rocking-Chairs; and I do hereby declare the following to he a full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains'to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention has as its object the construction of a rockin g-chair in a cheap and durable manner, allowing a free rocking motion instead of a movement upon a xed point or pivot or a pendulous movement.

It relates to that class of rockingchairs which have a base frame, upon which the upper portion or seat-frame rocks; and it consists, essentially, of a new and improved mode of connecting the base with the seat frame, so as not to interfere with thc free rocking motion of the seat and still secure a firm and durable connection between the two.

In the accompanying drawings, Figure lis a view representing a vertical section through the middle of the chair from front to back; and Fig. 2 a partial vertical section at right angles to theformer.

A is the frame of the upper portion of the chair, and B the rocker, forming the lower side piece of the seat-frame. This rocker is curved or arched on its lower edge, as shown in Fig. 1, and rests upon the bed-piece c, which forms one of the sides of the base frame or support for the chair. I prefer to have theV two meet squarely together, as shown in Fig. 2, but, if preferred, one may be hollowed and the other rounded on the line ot' the section shown in Fig. 2.

It will thus` be seen from the drawings and my description thus far that the seat-frame rocks upon the base with a rolling motion,just as an ordinary rocking-chair rocks upon the floor as a base, the point of support or contact between the two moving backward or forward with the motion of the chair.

D is a projecting ear, preferably formed of cast or malleable iron, hrmly attached to the inside of the rocker B by means of the plate g, and provided with a projecting lug, h, and a downwardly-projecting shank, a, in which is a curved slot, b, the form and relative arrangement, as well as the proportion of the various parts, heilig delineated in the drawings.

A projecting pin, d, is by means of a plate secured to the bed-piece c within the slot b, and serves to arrest the mot-ion of the rocker backward. I prefer to interpose a small block of rubber, cork, or other elastic substance between the points of contact at C.

To further retainthe parts in position, the l spring E-prelerably made long and thin and quite broad-is rmly fastened at its two eX- tremities -to the projecting lugs c and h, as shown in Eig. 1. This spring E lies inside the inner edge of bed-piece c, nearly parallel with its upper edge, and while it serves to hold the seat-frame in close contact with the baseframe it bends readily and permits a free rocking motion in the seat-frame. It should be so placed as to bring the chair into equilibrium at the position shown in Fig. 1.

It will be-observed that Figs. 1 and 2 show only onehalf the chair, the two sides being constructed similarly. y

By the use of the long flat spring greater simplicity and durability is gained, and also a freedom from all rattling and creaking,w'hich are almost inseparable from the use ot' rubber hands and spiral springs as a connection.

A great though incidental advantage in my device is found from this construction-admitting the use ot the arched rocker and the rolling, in contradistinction from the pivotal motion ot' the seat-frame.

I am fully aware that rocking-chairs provided with base frames and supports for the rocking or seat frame have been heretofore employed, and I neither claim them nor an elastic or spring connection between the two, broadly.

I am aware that rockingchairs have been mounted upon stationary bases and the two connected by means of springs of various forms and arrangement, and also that rocking-chairs have been provided with slotted arms operating in connection with pins upon the base to limit the rocking movement of the chair, and I do not claim either of said features, broadly. I am not aware, however, that any one has hitherto constructeda single arm in such man- IOO sisting of the curved slotted arm provided with a lateral ange, h, the spring E, provided with means for attachment to the chair, and the flanged arm d, provided on its under side with a recess, having the cushion C seated therein, 15 said parts constructed for joint operation, as described and shown.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

EDWARD KETTLER.
