WINDOW CLEANER.

Application ledkAugust 1S, 1922. Serial No. 582,325.

To @ZZ whom t 77mg/ concern:

Be it known that I, HARRY NEWMAN, a citizen of Rumania, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful mproveinents in VWindow Cleaners, of which the following is a clear and exact specification.

This invention relates to wiping or cleaning means for windows, and my improvements are particularly directed to a device of this character'wherein cleaning elements are applicable, simultaneously, at both sides of a window pane, and wherein the cleaner carrying and actuating means are included in the sash construction.

My invention further comprehends the construction of the sash frame wholly of metal with hollow sides, top and bottom, the,

sides having slots for the reciprocatorypassage of the cleaner carrying means, the top containing spring return means for the, cleaners, and the bottom containing spring' return means for closing the slots in the sides as and when the cleaners are moved up! wardly.

Other features and advantages of my 1nvention will hereinafter appear.

In the drawings Figure 1 is a front elevation of a window sash embodying the features of my invention.

Fig. 2 is a top plan view thereof, partly in section.

Fig. 3 is a section on the line 3-3 of Fig. 1.

Fig. 4 is a horizontal linc 4 4 of Fig. 6.

Fig. 5 is a vertical section taken on the line 5 5 of Fig. 1.

Fig. 6 is a fragmentary view, partly in section, of one upper corner of the sash, and

Fig. 7 is a detail sectional view showingr the cleaners and taken on the line 7-7 of Fig. 4.

In these views the window sash will be seen to comprise the side members 1 and 2, top 3 and bottom 4. These members or Stiles are composed of sheet metallic material and each has substantially boxdike structure, with its elements shaped and adapted to serve certain purposes. Thus, the top 3 is composed of the side elements 5, whose lower portions 6 are inturned, terminating in upturned flanges 7, that constitute a socket for the reception of the window pane 8; while section taken on the the upper ends of elements 5 are folded over inwardly, as at 9, to receive the upturned portions 10 of flanges 11 that depend from a closure, slide element 12, which thus Vremovably covers the box-like upper member 3.

The structure of this member 3 is reinforced by braces 13, secured as at 14 to the elements 5, and having upper flanges 15 to support slide 12. Similarly the side members 1 and 2 of the sash are each composed of side elements 16, which are actually the walls of a U-shaped formation, whose base is indicated at 17, and constitutes the inner portion of the stile. This inner portion 17 has a central indentation or groove 18 to receive the pane 8, and at each side thereof it is provided with slots 19, for a purpose to be referred to hereinafter. An outer element 20 is suitably secured to the elements 16, to complete the box-like formation, reinforcement being provided by means of the braces 21.

Secured to the element 20, as at 22, is a vertical guide 23 here shown to be angular in cross-section, the point of its connection with member 2O occurring at one of the corners of the guide. This guide extends up into the member 3, and is there provided with the inward bridgement 24, which completes its hollow formation, the bridgement 24 being provided with a squared slot or aperture 25, to receive the squared end of a shaft 26, forming part of a spring roller device which will be more particularly re ferred to hereinafter.

The guide 23, for the major portion of its length, is open at its inner side, to provide a vertical slot 27; and a carriage 28, which tits freely within the guide, and is slidable therein, has an extension that protrudes through this slot, outside the guide. The carriage is shown as comprising an angled member, conforming in cross-section sub stantially to the shape of the guide, and its extension is in the form of two arms 29, which respectively pass out through the slots 19, in which they are capable of sliding movement, said arms 29 each having a terminal portion 30, capable of engagement with the window cleaning members.

The window cleaning members are here shown as consisting each of a channel like frame 31, embracingV a number of tongues or plies of soft, flexible material, indicated at 32, having spacers 33, within the confines vported by tapes 34, 34,

of the frame, whereby the tree ends of the The cleansing members ext-end across the at each side thereof, and ai'e supwhich are attached respectively to an ai'ni29 of each cai'riage 28, and are wound upon a spring return roller 35. This roller' is hollow, with end caps 36, from which flanges 37 extend to prevent overrun oi the tapes.

The caps 36 have cent-ral holes 88 to serve as .bearings for the shaft 26. A helical spring .39' within the roller stores energy, in the manner of a shade roller, as the roller is rotated by the extension oi' the tapes in moving the cleaners downwardly, to thus automatically return the cleaners.A A handle 40 may be secured to one of the cleaners for the downward cleansing stroke of both cleaners, which is performed manually.

For the purpose of covering the slots 19 pane, one

when the cleaners are in their normal, up-

ward position, to thus vprevent the introduction of rain, dust, etc., into the hollow frame of the sash, l attach tapes 41, 41 respectively to each'arm 30 of the lcarriages at each side of the sash. These tapes 41 each extend through channels provided therefor that consists of opposed, U-shaped folds 42, 42 in the elements 16 and 17, the tapes thereby extending across, and closing slots 19; and spools 43, revolubly mounted in the lower :trame member 4, and provided with spring return means 44, serve to automatically wind up the tapes 41 vas the cleaner isV drawn downwardly; but the spring 89, being more poweriiil` than the combined springs 44, hastlie normal tendency to iinwind the tapes 41 with the return .move-V ment of the cleaners.

Variations within the spirit and scope of my invention are equally coiiiprehended by Vthe foregoing disclosure.
