IMPROVEMENT IN CHAIRS.

Specification forming part of Letters Patent No. 139,903, dated August 27, 1872.

ters of referencemarked thereon and being a p'art of this specitication, in which- Figure l is a perspective view of my improved chair. Fig. 2 is a partial perspective, showing the seat and the leg-supports inverted; and Fig. 3 is an enlarged longitudinal vertical section of an arm-rest, showing the ratchet-quadrant which sustains the back of the chair, and the spring-bolt which locks it.

Like letters refer to like parts in each gnre.

The nature of this invention relates to a chair which is provided with a simple device for forming an extension of the seat on a horizontal plane to support the occupant-s feet and lower limbs; and consists in the peculiar and novel construction of `the extension and its connection with the chair, as more fully hereinafter set forth.

In the drawing, A represents the frame of my chair-seat erected on four legs, B. O is the back-frame, hinged at the lower edge to the back rail of the seat-frame. At the back corners of the seat-frame are erected the standards a a', and to their tops are secured the segmental arm-rests b b, whose front ends are mortised in the sides of said seatframe. D D are ratchetquadrants or segments toothed on their lower edges, and are secured by pivots or otherwise to the side bars of the back frame. The under sides of the arm rests b are recessed lor grooved to receive the segments D. The tops of the standards a are bored to receive a pawl-bolt, c, which is pushed up by a spiral spring, d, placed below it in the hole.

A slot, c, is cut through the outer face of each standard, through which to insert a handle, f, and screw it into the bolt c.

When the back is sustained in an inclined position, by pushing it toward the vertical position theratchets are forced into the grooves of the arm-rests, and are held rmly in whatever position they may be left by the springpawls.

E E are two levers, the two equaling in size or area the seat-frame,- to thefront corners of which they are hinged, as shown. At the free end of each there is a pendent supporting leg, g, which supports the leaf in its horizontal plane, whether swung back against the side of the seat-frame, as shown, or when swung around to the front, as shown in dotted outline, to form a leg-rest for the occupant. To loclr the leaves in this latter position, to the under side of one of them a button, h, is pivoted, andv engages with a segment-clip, i, on the under side of the other. Tov secure the leaves when folded back against the seatframe, a button, h', pivoted under the frame, engages with a clip, i', under the edge of the leaf, as shown in Fig. 2 of the drawing.

The chair may be made of wood and upholstered so as to furnish a luxurious article with which one may take comfort in various positions and at a small cost.

What I claim as my invention, and desire to secure by Letters Patent, is-

rlhe leaves E E, provided with the supports g, buttons h, and clips t', pivoted or hinged to the seat-frame A of a chair, as and for the purpose set forth.

JAMES DEFOE.
