CHAIR.
SPECIFICTION forming part of Letters Patent No. 291.366, dated January 1, 1884.
Application filed May 5, 1883. (No model) To a/ZZ whom it may concern.- Be it known that I, JAMES B. LINN, of Toledo, in the county of Lucas and State of Ohio, have invented a new and Improved Chair, of which the following is a full, clear, and eXact description. t
The object of my invention is to provide a new and improved chair the seat of which can be" rocked slightly.
The invention consists in a chair constructed with a seat having rockers on the bottom, which rockers are provided with downwardlyprojecting lugs passing through pockets in a frame supporting the seat, which lugs are surrounded by springs contained in the pockets. The said springs pull the seat back into the normal position in case it is rocked.
Reference is to be had to the accompanying drawings, forming part of this specication, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation of my improved chair. Fig. .2 is a cross-sectional elevation of the same on the line mx, Fig. 1, parts being broken off. Fig. 3 is an enlarged detail sec- Fig. 1.
On a suitable standard, A, adapted to be secured on the floor, a skeleton frame, B, is fastened, onwhich two slightly-curved rockers, C, rest, which are attached to the bottom of the chair-seat D at the side edges of the same. From the middle of each rocker a lug or jaw, G, projects downward and through a longitudinal pocket, H, projecting downward from the. skeleton frame B. The lug G is surrounded by a piece of rubber tubing, J, or other spring, contained within the pocket H and resting on a plate, K, through which the lug passes, which plate rests on a transverse pintle, L, passed through the bottom of the lug. The seat is provided with a back, M, in the usual manner.
The frame B can be arranged to turn on the standard in the same manner as in other revolving chairs, it' desired.
The seat can be rocked forwardor backward on the frame B, and is always drawn back into its original position by the spring J. The motion of the chair is very easy `on the spine, and makes the chair very comfortable. It is especially adapted for use as a desk-chair in schools, meeting-rooms, churches. 8vo.`
Having thus described my invention, 'what the purpose speciiied.
