WINDOW-CLEANING CHAIR.

SPECIFICATION forming part of Letters Patent No. 565,764, dated August 11, '1896. Appiicaion ned April 11,1895. staand. 545,363. (No man.)

To all whom it may concern.-

Be it known that I, JAMES S. LYNCH, of Brooklyn, in the county of Kings and State of New York, have invented a new and `Improved lVindow-Cleaning Chair, of which the following is a full, clear, and exact description.

My invention relates to a window-cleaning chair, and the object of the invention is to provide a chair for such purposes which will be as simple in its construction as a chair for ordinary use and as readily manipulated; and a further object of the invention is to provide an exceedingly simple and economic locking device for securing the chair in position for use on the outside of the window.

The invention consists in the Vnovel construction and combination of the several parts, as will be hereinaftei1 fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in. which similar figures and letters of reference indicate corresponding parts in all the views.

Figure lis a vertical section through a portion of the window-frame and its sill, illustrating the chair as secured on the sill, the chair being in side elevation; and Fig. 2 is a perspective view of the chair.

In carrying out the invention the chair consists of the bottom A and the back B.` The front edge of the bottom is straight, and preferably the entire bottom is of somewhat semispherical shape in outline, (although it may be given other contour,) and the back B is made of corresponding shape. The back may be Of any character, that shown in the drawings comprising a series of vertical bars 10 and a rail ll, connecting all the bars at the top.

The back of the chair is provided with a front vertical bar l2, round in cross-section, located at each side, these front bars being secured to the ends of the rail ll, and the aforesaid front bars are of metal, and are preferably each provided with a stop 13, in the nature of a shoulder, at a predetermined point in its length; but the stop may be omitted if desired.

In connection with the body of the chair clamping devices C are employed. These devices are two in number and are of like construction, each comprising an angled bar consisting of a horizontal member 14 and a vertical member l5, the latter being at the inner end of the horizontal member, the outer end of the said member terminating in an eye 14a, through which one of the front metal bars l2 of the chair-body passes. This angle-bracket is therefore capable of sliding freely on or of swinging lon the front bar l2, and at the lower end of the vertical member l5 of the angle-bracket an eye l5 is formed threaded to receive a horizontal adjusting-screw 16, having a head at its outer end, preferably having attached to it or being covered by a cushion 17.

In operation the chair is placed with the bottom of its body on the outside window-sill of the window-frame, the front straight portion of the said' bottom bearing against the Outer riser of the lower sill of the windowframe proper, as shown in Fig. l, the brackets of the clamping devices being immediately slid up on their supports until their vertical members are in front of the wall-space below the inside edge of the window-sill. I hey are then permitted to drop to an engagement with the stop 13, and the adjusting-screws 16 are manipulated until their cushioned ends firmly bind against the wall-surface beneath the inside window-sill. The brackets and the clamping devices are made of a size to readily receive any window-frame, the difference in width being provided for by the manipulation of the adjustingscrews 16. This device is exceedingly simple, durable, and economic, and when attached to a window provides a perfectly safe seat for a person when cleaning a window. l

By the construction of the device as above described it will be seen that when the improved chair is not required for use the clamping devices C may be slid up on the vertical bars l2 of the chair, and when slid up may be folded inwardly inside the back of the chair, so that the device will occupy comparatively little space.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a window-cleaning chair, the combination of a back and seat having at its for- IOO ward part vertical bars, and clamping devices having their outer ends provided with means to engage the window-sill, said clamping devices having their' inner ends arranged to slide on the vertical hars and being adapted when slid upward to be folded within the back of the chair, substantially as set forth.

2. ln a window-cleaning chair or the like7 the combination of a seat, a back comprising a series of vertical bars secured at their lower ends to the upper part of the seat, and a curved rail connecting said vertical bars at their upper ends, clamping devices coin- JAMES S. LYNCH. lVitnesses:
