CHAIR.

SPECIFICATION forming part of Letters Patent No. 348,633, dated September 7,1886.

(No model.)

To all whom it may concern.-

Be it known that I, THOMAS ATKINSON MOFARLAND, of Meadville, Crawford county, Pennsylvania, have invented an Improved 5 Seat Attachment to Chairs, of which the following is a specification.

The object of the invention is to cause the seat not only to have an up-and-down but also a rocking or swinging motion.

Figure 1 is a vertical section through back and seat; and Fig.2, a horizontal section,whieh is in a plane passing under the arms.

In the drawings, A represents the chairframe; B, the arms; and C,the seat suspended :5 from the arms by the spiral springs D, of

which there are preferably four, two being pendent from each arm.

In order to give the desired rocking motion as well as an up-and-down one, it is obvious 20 that the corners and parts next thereto must be set at such distance from the legs E that room will be allowed for the swinging motion.

The sitter can thus not only, by pressing the floor, raise himself up and down, but can vary the exercise by rocking himself back and forward.

I am aware that chairseats have been arranged upon subjaeent springs, but believe that no one has ever suspended the seat so as to bring it beneath the springs for the purpose of permitting an up-and-down as well as a for ward-and-back rocking motion; hence Vhat I desire to. protect by Letters Patent 1s The combination, with a chair-frame having arms and legs substantial] y as described, of the seat C and springs D, said seat being cut away at the corners and suspended by the springs from the arms to swing clear of the legs, substantially as shown and described. THOMAS ATKINSON MGFARLAND.
