CONVERTIBLE CHAIR.

SPECIFICATION forming part of Letters Patent No. 533,727', dated February 5, 1895. Application filed December 29, 1893. Serial No. 495,112. (No model.)

To all whom t may concern:

Be it known that I, JOSEPH G. MGGAFFREY, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Convertible Chairs, of which the following is a speciiication, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in combined chairs and couches.

The object of the invention is to providea combination chair and conch which can be easily and quickly adj usted into any desired position and which, when not in use, may be folded up to occupy a limited amount of space.

With these and other ends in view my invention consists in the peculiar construction and arrangement of parts as will be hereinafter fully pointed out and claimed.

In describing the invention in detail, reference is had to the accompanying drawings, which form part of this specification and wherein like letters indicate corresponding parts in the several views, in which-- Figure l, is a view in side elevation showing my improved chair converted into a couch 3 also by dotted lines various adjustments of the foot and head portions ot' the same. Fig. 2, is a similar view showing arearrangement by which the same is converted into a chair and also showing by dotted lines several positions which it may be made to assume. Fig. 3, is a bottom plan view of the chair. Fig. at, is a detail view of the means for locking the legs of the supporting frame.

In the drawings: A, denotes a rectangular frame formed by the longitudinally extending rails ce, a, and the transverse braces a2, a2. Between the rails a., o, adjacent the braces a2, a2, are pivotally mounted supporting legs 0.3, as, arranged in pairs and each pair connected by a cross beam. These legs are adapted, when the chair is not in use, to be folded inwardly, between the strips a, a, and are provided on the sides adjacent the braces with stop-shoulders a4, which abut against said braces and serve to retain the legs at a determined inclination. As a convenient means for retaining them in such position, I

pivot to the under side of each rail a, adjacent the legs, an arm a5, which may be swung across the frame and into engagement with notches as, of the legs, thus holding them firmly in position. The free ends of these arms a, are preferably reduced as at a7, for engagement with notches as, of the pivotal latches ai.

On the outer faces of the rails a, a, are pivoted the side bars b, b, of the chair-back, which are connected at their free ends by a cross brace b2. This brace, when the bars are in a horizontal position (see Fig. l) rests in pockets am, formed in the rails a., o. The back is supported at any desirable angle to the supporting frame by a brace comprising the side arms 114, b4, pivoted to the bars o, b, and connected bya transverse rod b5, which is adapted to engage the notches au, of the rails a, a.

C, denotes the leg and foot-rest formed of sectionsc, ci, c3, which are hinged together as at c4. The projecting arms of the inner section are pivotally mounted on the side rails a., ce, with the free ends thereof connected to the back-portion by the interposed arms D, b, which latter have a pin and slot connection b", with the back proper. The outer section o8, is provided with eye-bolts c5, c5, into which the hooks c6 of the intermediate section c2, take to secure said section c3 at an angle of inclination suitable for different positions of the chair.

By making the leg and foot rest in three sections and connecting said sections in the manner shown and described such rest as a whole may be folded over on the supporting frame at the upper joint c4, so as to lie, in knockdown form, within the length of the side bars of the main frame for the purpose of storage or shipment.

D, denotes a covering of suitable material which is secured to the side rails as at d, to form a seat portion, with one extremity eX- tending inwardly and entirely covering theback-portion and the opposite extremity eX- tending in an opposite direction to cover the foot and leg rest. Thus, referring to Fie. l, when the parts are positioned as there shown, a continuous horizontal conch will be presented. This at surface may be broken at either end, of the seat portion by depressing the joint l, in the direction of the arrow, which would tend to elevate the leg and footroo rest, as is also indicated by lines 2 and 3, and

by giving the button bs, a partial revolution,

t cause it to engage the under side of the rail,

these parts may be retained as adjusted. 5 Again, the outer section c3, of the leg and foot-rest may be elevated and secured bythe hook and eye above referred to. Again the back portion may be readily elevated to an angle of forty-live degrees tothe seat portion without necessarily disturbing the leg and foot-rest, owing to the pin and slot connection between the back and the interposed arms connecting the same with the foot-rest.

Referring to Fig. 2, the extreme forward position of the chair is shown by full lines, also the leg and foot-rest adjusted thereto and several intermediate adjustments indicated by dotted lines, which will be readily understood.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, isu

l. In a chair ofthe class described, the combination with a supporting frame, having a seat rigidly secured thereto, of a back portion pivoted to the frame, adjacent to one end of the seat thereon, arms pivoted to the back and adapted to take into notches in the side bars of the frame, a leg and foot rest having its side bars pivoted to the supporting frame near the forward end thereof, and bars pivoted at one end to the leg and foot rest and connected with the back by a pin and slot connection, substantially as shown and described.

2. In a chair of the class described, the combination with a supporting frame and a back pivoted to said frame and adapted to be supported at dierent angles with relation thereto, of a leg and foot rest comprising a section which is pivoted to the supporting frame, and two sections hinged together and to the pivoted section one of said hinged sections having secured thereto hooks adapted to take into eyes carried by the other of said hinged sections, and bars pivotally connected to the leg and foot rest and adjustably connected to the chair back, substantially "as shown and described.

3. The combination with a main frame, of leg frames arranged at each end of the main frame and each consisting of a pair of legs pivoted to the main frame and connected by cross bars, locking bars pivoted to the main frame, adjacent to each leg frame to swing transversely across the same and tin notches formed in the legs, the free end of each of such bars being reduced in thickness, and latches pivoted to the main frame to swing at right angles to the line of movement of the locking bars and adapted to engage the reduced free ends of said bars, substantially as shown and described.

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

JOSEPH G. MCGAFFREY.
