COMBINED CHAIR AND WINDOW-CLEANERS SUPPORT.

Specification of Letters Patent.

Application filed December 9, 1911.

Patented Feb. 20, 191.2.

Serial No. 664,721.

To all whom it may concern:

Be it known that I, MAX RABINOWITZ, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Combined Chairs and Window- Cleaners Supports, of which the following is a specification.

This invention relates to improvements in a combined chair and window cleaners support.

The object of the invention is to provide a device of this character which, when not in use as a window cleaners support, may serve as a sightly house chair.

A further object of the invention is to provide a strong and rigid construction which, when a portion. of the device is used as a window cleaners support, a person of any weight will be supported with absolute safety and in such position as the user can conveniently reach the outside of the window when occupying the support.

A still further object of the invention is to provide an adjustable means which may be adjusted to different widths of windows and held positively and rigidly in such adjusted position, maintaining the support centrally, in the window opening when desired, but capable of being so adjusted that it may occupy a position to one or the other side of the window center, as may be desired.

Another object of the invention is to provide a construction in which the part which serves as a window cleaners support may be readily attached to and detached from the lower or leg portion of the chair.

In the drawingsFigure 1 is a perspective view of the device complete; Fig. 2 is a plan view of the upper part of the device, shown in connection with a window portion of a building, showing the manner of holding the support in position for window cleaning; Fig. 3 is a cross section of the chair complete; Fig. 4: is an enlarged cross section of the sleeve in which portions of the chair arms slide and are held; and Fig. 5 is a detail perspective view of one of the arms removed from the casing.

Referring to the drawings, the numeral 1 designates the body of the chair, which I preferably make of wire. The frame comtion to form the bottom side pieces 5, which side pieces are in turn bent at their forward ends to form short downwardly extending side pieces 6. The side pieces are connected by a transverse wire 7. Connecting the side pieces of the frame at the bot-tom of the chair, is a transversepiece 8. Connected to the side pieces 5 preferably about medially thereof, are oppositely disposed pieces 9 which extend upwardly where they are connected at the corners to the back of the chair as shown at 10, thus forming two side guards. The frame thus formed is provided with other vertical and horizontal wires, preferably smaller or lighter than the pieces constituting the main frame, any number of which may be used, and these may be connected to the main frame in any approved manner, or they may be dispensed with entirely and the frame of the chair may be covered with canvas or other suitable material.

Attached to the cross piece 4: at the back of the chair is one end of a piece 11, which extends forward where it is connected with the side piece 9. This piece is duplicated at the opposite side of the chair and is suitably braoed by cross pieces 12, and short vertical ties 13, thus forming, with the bottom of the chair, two triangular pieces which extend below the bottom of the chair. These pieces are adapted to rest on the window sill outside of the window and maintain the support in horizontal position.

Rigidly secured to the front of the frame, is a sleeve 14, preferably rectangular in cross section and provided at intervals at its top and bottom, with perforations 15, the purpose of which will presently become apparent.

Centrally supported within the sleeve is a transverse partition 16 which has perforations, or apertures 17, registering with the perforations in the top and bottom of the casing. The casing is open at both ends and adapted to receive above, and below the partition 16, the flattened bars 18, of two adjustable arms 19. The flattened portions 18 are provided with perforations or apertures 20, for the passage of removable pins 21, which are adapted to extend through the casing, the bars 18 and the partition 16, that is to say, through the perforations in these parts, to hold the arms in lateral adjusted position. The arms 19 extend upwardly and their upper ends are bent rear wardly so that when the device is being used as a chair, they will extend back to the side pieces 9, to which they may be attached temporarily or while the device is serving as a chair, to hold the arms in rigid relation with the rest of the chair. This attachment may be made by means of small hooks 22, as shown.

The bottom of the chair comprises in the main, a top support 23, rectangular in shape, provided with legs 24 braced by rungs 25, as usual. Passing through the bottom of the chair are cleats 26 having hooked upper ends 27 which pass through the spaces between the tie wires of the bottom of the chair, and are adapted to be turned laterally to overhang the side pieces to firmly secure the upper and lower parts of the device together.

It will be observed that the construction of the sleeve on which the sliding portions of the arms slide, and are adjustably held, will permit of the use of flattened portions for each arm, equal to the entire width of the front of the chair, so that the extent or degree of adjustment of the arms, may be very considerable when they are used as retaining devices for holding the support in position for window cleaning. They fit snugly within the spaces above and below the partition 16, so that there is no possibility of twisting or turning within the casing as would be the case were the partition not present.

In using the device as a window support, the user gages the width of the window opening and correspondingly extends the arms, sliding the flat portions of the arms within the casing, until the desired width is obtained, when the short pins 21 are inserted through the registering holes in the top and bottom of the casing, the sliding flattened portions of the arms, and the partition, thus making a firm and rigid lock between all of the parts. The device is now extended through the window with the arms in en gagement with the wall adjacent to the window frame, in which position the window cleaner can occupy the support with perfect safety, as obviously it is impossible for the device or occupant to fall through the window opening on account of the engagement of the side arms with the wall.

Changes in detail of construction may be made without departing from the spirit of the invention, and while I have shown the body of the chair in the main made of wire, it will be understood that it may be made of any suitable material.

Having thus fully described my said invention, what I claim is- 1. In a combined chair and window cleaners support, the combination with a suitable seat, of a casing carried by the front part thereof, of members having portions slidable in said casing, and extended upwardly to form chair arms when the device is used as a chair, and retaining devices when the seat is used for window cleaning purposes, and means for holding the mem bers in adjusted position in the casing.

2. Ina combined chair and window cleaners support, the combination with a suitable seat, of a perforated casing, rigidly secured to the front thereof, of two members having flattened perforated portions, said members being slidable in the casing, and extended upwardly to serve as arms when the device is used as a chair, and as retaining devices when it is used for window cleaning purposes, and a removable pin adapted to extend through the perforations in the casing, and those in the slidable members, whereby the members are held in adjusted position.

8. In a combined chair and window cleaners support, the combination with a suitable seat, of a casing secured to the front part thereof, two members having portions slidable in said casing, said portions extending substantially for the full width of the seat, and having extensions outside of the casing, which extend upwardly and serve as arms when the device is used as a chair, and as retaining devices, when used for window cleaning purposes, and means for holding the slidable members in adjusted position.

4. In a combined chair and window cleaners support, the combination with a suitable seat, of a perforated casing secured to the front part thereof and having a central perforated partition therein for substan tially its entire length, members having perforated portions slidable in said casing, one above the partition andthe other below, said members having extensions outside of the casing that extend upwardly to form chair arms or retaining devices for the purposes described, and pins adapted to extend through the perforations in the casing, sliding portions of the members, and the partition in the casing, to lock said members in adjusted position.

5. In a combined chair and window cleaners support, the combination with a suitable seat, of a casing carried by the front part thereof, of members having slidable portions in said casing, said members out side of the casing being extended upwardly the leg portion, all substantially as and for to form chair arms when the device is used the purpose set forth. 10 as a chair and retaining devices when the In testimony whereof I afliX my signature seat is used for window cleaning purposes, in presence of two witnesses.
