IMPROVEMENT IN FOLDING CHAIRS.

Specification forming part of Letters Patent No. 200,211, dated February 12,1878; application filed.

March 12, 1877.

To dll whom it may concern:

Be it known that I, Eugene. H. Mahoney, of Boston, county of Suffolk, and State of Massachusetts, have invented certain Improvements in Folding Chairs, of which the following is a specification, reference being had to the accompanying drawings, in which similar letters refer to similar parts.

In Figure 1 a vertical sectional view of the chair as set up for use is given. Fig. 2 represents it folded.

This invention relates to certain improvements on the chair as patented to George C) Paine, September 19,1876; and consists in introducing the link or bar D, for the purpose of connecting the front and rear leg-frames, in the manner as clearly shown in Fig. 1.

The front and rear leg-frames of this chair are constructed in the manner usual to the ordinary cross-legged folding camp-stool. A back-frame, A, is provided, which is pivoted to the upper ends of the front leg-frame 0, which thus becomes the rear part of the seat. The posts of the back-frame extend below the point where they are pivoted to the seat, and their lower ends are pivoted to the rear legframe B at a point about half-way between the lower ends of the rear leg-frame B and the point where the front and rear leg-frames cross each other. The link or bar D is pivoted to the rear leg-frame B a little above its lower extremity, which may be upon the stretcher which connects the leg-frames transversely. The opposite end of the link or bar D is pivoted to the front leg-frame 0 a little above (which, of course, brings it to the rear of) the point where the legs of the chair cross each other.

The use of this link or bar adds to the utility of the chair, as constructed according to the patent of George 0. Paine, already referred to, in that it causes the front leg-frame to assume its proper position as the chair is set up for use or folded, as the case may be.
