'SPRING=CHAIR.'

SPECIFICATION forming part of Letters Patent No. 298,936, dated May 20, 1884.

I Application filed June 7, 1883. (No model.) I

To aZZ whom it may concern Be it known that 1, ANDREW M. BLAKE, a citizen of the United States, residing at O0- lumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in SpringOhairs, of which the following is a specification, reference being hand therein to the accompanying drawings.

This invention relates to certain improve ments in chairs; and it has for its objects to provide an improved spring and means of attaching the same to the chair, as more fully hereinafter specified. These objects I attain by the means illustrated in the accompanying drawings, in which-- Figure 1 represents a perspective view of a chair showing my invention, and Fig. 2 rep resents a perspective view of the cross-bar and spring to be attached to the legs of the chair.

In the drawings, the letter A indicates the base of the chair, which consists of four legs, B, connected by the usual rounds,(). The upper ends of the forward legs have secured to them a strong crossbar, D, and to the upper ends of the rear legs and the seat-frame is secured a similar bar, E. These bars have secured to them the elliptic springs F G, which support the seat H, which is securely fastened to said springs. The letter I indicates a crossbar attached to the lower ends of the front 0 chair-legs. To the center of said. bar is secured an elliptic spring, K. The said bar is slotted longitudinally at each end, in order to adapt it to chairs of different widths. The bar may be slightly bowed, as indicated, to 3 5 prevent raising thefront of the chair too high.

As thus constructed ,a strong and substantial chair is produced, which serves as a rockingchair, and a spring-chair in addition.

- It is evident that a cross-bar and elliptic spring may be secured to the back legs of the chair, if desired.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

An elliptic spring, in combination with a metallic bar having slots at its ends, whereby the whole may be secured to the legs of chairs of different widths, substantially as and for the purposes specified.

In testimony whereof I affix my signature in presence of two witnesses.

ANDREWV M. BLAKE.
