' WINDOW CHAIR. 'No. 367,259. Patnted July 26, 1887.

N, FEIER5. Photo-Lithographer. Washinginn, by C4 UNITED STATES PATENT OFFICE. I



SPECIFICATION forming part of Letters Patent No. 367,259, dated July '26, 1887.

Application filed February 23, 1887. Serial No. 228,463. (No model.)

To aZZ whom it may concern.-

Be it known that I, ANTON WITEK, a citizen of Austria, residing at New York, in the county and State of New'York, have invented a new and Improved Window-Chair, of which I the following is a specification.

, improved window-chair.

ing, andV thewindow-frame. Upon the horizontal portion of this frame there is placed the improved'window-chair, consisting, essentially, of a pair of clampingjaws or legs pivoted to a platform. This platform is composed of side rails, a, connected in front by a cross-piece, b, having projecting shoulders b,

and at the rear by a cross-piece, d, which serves against thewall W, and by locking the rear to support the person who is to occupy the chair. The forward leg or clamping-jaw, c, is hinged to the cross-pieces a by pivots c, and abuts against the stops 6, which prevent such jaw from receding from the wall W and keep thejaw down at right angles, as shown. The

rear jaw consists of two rods, w, pivoted at w" to cross-piece, a, and joined at the center by a cross-bar, w, and at the lower end by a clampplate, 10*, placed at an oblique angle to rods w. The rear jaw is pivoted to the rear end of the platform, so that it may be inclined toward the wall.

By swinging the rear jaw upon its pivots it is evident that the plate 10 may be pressed plate in position the entire chair will be locked to the wall. In order to look the rear jaw, I

which may be slipped over a hook, 8. By drawing the chain taut and then slipping the chain-link over the hook the clamp-plate will be properly locked against the wall.

To afford an additional security, especially against breaking of the chain s, I cut into one or both of the rods 10 a rack, as shown at 1", which is engaged by a pawl, p, pivoted to lugs q of rails or. This pawlis connected to ahand rod or chain, a, which can be locked to a button, an. After the jaw has been swung in position the pawl is swung up to engage the rack, and then the chain'o is locked to the button :11. Thus a double security is obtained against accidents. Upon the platform there is mounted a frame that may be folded, if desired, and

which is to prevent the occupant from falling from the platform. This frame consists of two rear uprights, f, and two front shorter uprights, 6, pivoted, respectively, at f and e to side rails, or. The two uprights are joined by crosspieces a and a", and are provided with the arms h and is, pivoted, respectively, at h and k. The arms h and 7c are perforated or slotted at their free ends, to he slipped over a stud or pin, m, on uprights e. Thus the entire frame is self-supporting. To fold the frame together, the arms h 7c are released from studs m and folded down, and then all of the four uprights may be folded upon the platform.

What I claim is-' v The combination of a horizontal platform having frontjaw, c, with a rear jaw composed of arms w w, pivoted to the rear end of the platform and carrying an oblique clamp-plate, 10 one of the rods to having a rack, r, and with the pawl 19, and with chains and hooks for holding the rear jaw against the wall and the pawl against the rack, substantially as specified.
