SPRING ROCKING-CHAIR.

SPECIFICATION forming part of Letters Patent No. 426,053, dated April 22, 1890.

Application filed February 21, 1889 Serial No. 300,713. (No model.)

To all whom it may concern:

Be it known that I, OSCAR II. ORDWAY, a citizen of the United States, and a resident of Mattapoisett, in the county of Plymouth and State of Massachusetts, have invented new and useful Improvements in Spring Rocking- Ghairs, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in spring rocking-chairs, and it is carried out as follows, reference being had to the accompanying drawings, wherein- Figure 1 represents a vertical section of the improved rocking-chair. Fig. 2 represents a plan view of the base and its springs. Fig. 3

represents a cross section on the line X X shown in Fig. 1; and Fig. 4 represents an enlarged detail cross-section of the rocker, its spring, and connecting device.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

A A represent the sides of the base, which are held together at a proper distance apart by means of stays, rounds, or braces 04, a, and a, as shown, said stays being firmlysecured to the base parts A A by means of bolts, screws, or equivalent or well-known devices. a a are rounds or braces connected and secured to the stays a a", as shown in Fig. 2.

I desire to state that I do not wish to confine myself to the particular form of base shown and described, as the same may be varied, as may be desired, without departing from the essence of my invention.

B B represent the curved rockers secured to or forming parts of the chair-frames B B, and 0 represents the seat as is usual in spring rocking-chairs.

b b are stays, rounds, orbraces for securing the rockers together at a proper distance apart.

In connection with the stationary base and the curved rockers, I use a pair of springs, portions of which serve as tracks 011 which the chair is supported and rocked. Each of these springs is constructed and arranged as follows: It consists of a spring-metal bar (I, that is secured in one end in a suitable manner, preferably by means of a nut d, to the round a or other stationary part of the base, as shown in the drawings. The spring-bar b is made straight, or nearly so, between the rounds or projections a and a, and at the latter place it has a semicircular, or nearly so, bend d going around a portion of the stationary brace or projection ct, as shown, said spring terminating below the rocker as a yielding rod (1 the end of which is suitably connected to the rocker at or near its middle portion, preferably by means of a link e,having an eye in its lower end for receiving the free end of the spring-rod (Z and pivoted in its upper end to the said rocker by means of a screw, pin, or rivet f, passingloosely through a perforation in said link, as shown in Figs. 1, 3, and 4.

Each rocker B has on its under side a longitudinal groove 1), (shown in Figs. 1 and4,) which serves as a guide for said rocker as it is rocked forward and back on the springtrack (Z.

By rocking the chair forward or back beyond its middle position, (shown in Fig. 1,) the free end of the rod (Z will be bent upward against the influence of its downward springpressure and causing the body of the chair to be automatically returned to its normal central position as soon as the occupant ceases to press forward or back on said chair-body. By this arrangement I produce a very light, strong, and durable rocking-chair with a very easy and agreeable rocking motion.

If desired, suitable stops may be added to limit the rocking motion of the chair, or the rounds a Z) I) may be used for this purpose.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim- The rocking-chair as described, consisting of the base A A, its stay or projection a, and rockers B B, combined with the springs (Z (1 d secured in one of their ends to the said base, bent around and supported 011 the projection a of said base, and connected in their free ends to the said rockers, substantially as and for the purpose set forth.

I11 testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 23d day of October, A. D. 1888.
