is to so construct and arrange the cleaner that it will not increase the ordinary dimensions of the window or its frame and will not interfere with the easy opening and closing of the window.

At a suitable point in the glass, usually tid a little below the eye level of a man of ordinary height, is cut a hole 5. In this is placed a thimble 6 to constitute a bearing, and this thimble has a ange 7. A disk 8 apertured' to accommodate the thimble is,y

Elaced at the inside of the glass. Preferaly, a gasket or washer 9 otfelt, rubber or other suitable material is placed between flange 7 and the glass and between disk 8 and the glass to insure an even cushioned contact of these clamping devices with the glass. These washers 9l are also supplied With holes 10 which have a suction etlect to insure the more complete .clamping of the thimble to the glass.

Within the bearing formed by thimble 6 is revolubly mounted a stud 11 constituting the shaft of hub 12, which is dished to accommodate flange 7. To the hub the cleaner arm or arms 13, 14.- are secured; These will be more particularly described later. EX- tending inward from this inner end, stud 11 has a screw-threaded bore 15 and at the bottom of this bore is an angular socket 16. In a particular example this socket may be of square cross-section. A nut 17 is provided to engage screw-thread l5, and this nut has passing through it an angular hole l A cap nut 20 Vis provided, having an internal screw-thread 21 to engage an external thread formed on the inner end of thimble 6. At the outer end` this cap nut has atop 21a apertured at the center.

A square-stem 22 is provided to it the square hole innut 17 and the square socket 16. This stem has an enlarged head 23 passing through the hole in the top 21a of cap nut 20.` `A flange 24 is fixed on the stem against the inner end of head 23. An operating handle or key 25 is provided, having a clevis 26 to accommodate head 23. At

preferablyl itu each side of the clevis is an eye 27 and the in the bearing in thim and said eyes27. In a preferred construction, the hub 12 is provided with two

arms

13 and 14 and these may be arranged at an an le to the glass. Arm 13 may be provied with a rubbing and cleaning strip 13 of rubber or other` suitable material and the other arm may be provided with a beveled edge 14 to directly engage the glass and cut therefrom sleet or ice. Evidently, the number of arms may be varied if desirable, also the particular construction of the arms and their rubbing or scraping devices may be varied at will.

In applying the device to the window after the hole 5 has been made therein, the flanged thimble 6 and disk 8" are first p ut 1n place, a's previously described. 'llhe -dished hub 12 is then put in osition with stud 11 Ele 6. Nut 17 is then screwed into. the stud. Cap'nut 20, stem 22 with its flange 24C and handle 25 are usually assembled in the positions shown 1n the drawing -in the course of manufacture. Stem 22 may now be inserted in the hole 1n nut 17 and the nut may be tightened as much as desired by turning the handle, the stem 22 servingl as a wrench. rllhe 4hole in the nut is left in line with the socket 16 and stem 22 is pushed farther in until it engages the socket. The cap 20 is then screwed up on the thread of thimble 6 until the inner end of the cap bears against disk 8 and the disk and flange 7 are drawn together to clamp the glass about the hole with suiii# cient tightness, 1 preventing the bearing thimble 6 from rotating and strongly reinl forcing the glass about the hole. In screwing up the cap 20, stem 22 enters farther into socket 16.

It will be noticed that theabove described construction and arrangement provides for lvarying thicknesses oi? glass. With a thinner or thicker glass thecap nut 20 will be screwed a eater or less distance inward upon the t imble and stem 22 will enter more or less into the socket 16. The clean- .ing device may thus be. adapted to any thickness that may be encountered in use without any particular attention on the part of the workman and will operate satisfactoril in any case.

Willen the parts are in position as described, ordinarily the

arms

13, 14 are left horizontally, as in Fig. 1. The pin 28 of handle 25 is arranged parallel to the arms so that when not in use the handle hangs' downward as in Fi s. 2 and 4, parallel to the glass. The win ow ma then be opened an closed without inter ering with' the c ing, the design of the rilarts being such that the end of head 23, t e part farthest away from the glass at the inside, will clear the casing without interference. v In an eX- treme case, if the sash is unusually thin, and the head 23 mighttherefore strike the inner art of the sill, a slight notching of the sil at this oint would be sucient l and the stem 22 engaging socket 16 will ro-' tate hub 12 and the arms and clear a cii'-, cular space C on the window to afford clear' viion. When the arms are left in horizon- 'ut of the way. f.

rllhe appliance may be easily and quickly removed 1n a manner which will be evident from the revious description.

To acilltate the application of the device to the window, in some cases it may be desirable to provide registering perforations 30 in hub 12 and disk 7. In setting up the appliance a pin may be inserted in these erforations so that the hub and flange will e temporarily locked together. The setting up of nuts 17 and 20 ma thus be accomplished without the possibility of the thimble 6 and its ange revolving during these operations. y A

The hole 30 may also be utilizedas a lubricating device by providing the outer face of liange 7 with a groove 31 leadin hole 30 to the bore of thimble 6 so t at the bearing may be easily 'oiled' through the hole 3 Fig. 7 shows a modification in which stem 22 simply engages a socket in nut 17, this socket not being extended entirely throu h the nut and no socket being provided in tie hubi 12. This arrangement is satisfactory when the handle is turned in a direction correspondin vto the lead of screw of nut 17; that is, i? the screw is right-handed the handle may be turned right handedly without loosening the nut. Or, if separate, independent means are provided for locking the nut, the handle in this case maybe turned.

in either direction.

Fig. 9 shows another modification in which the bearing comprising thimble 6, flange 7, its Icoperating disk 8 and cap nut 2 0 are substan'tlally as in'Fig. 3. A bolt hole 35 is in this construction bored entirely through stud 11. At the outer end of this hole is an angular countersink 36. This may be square in a representative embodiment. Bolt 37 passes through hole 35 and extends therefrom and has a head 38 to fit countersink 36. Within the countersink -under the head of the bolt, maybe placed one or more washers 3 9..` Near its inner end the bolt is provided with a slot 40. Upon the bolt isV screwed a flanged nutftl hole toreceive a gin 42 which also through slot '40.

he pin engages'eyes 27 l position and the handle isreleased, it` f////,iv/ill fall parallel with the glass and entirely from of a handle 25 similar to the one-previously described.

When the device of Fig. 9 is to be applied to a relatively thick glass, some or all of the washers 39"are removed and the bolt head stud 11 and its hub in revolubleposition.

The holes in the nut are brought in line with slot 40 inthe bolt; eyes 27 of the handle are placed in line with the holes' and the pin 42'inserted; the parts are thus retained positively in operative position. ln case of a thinner glass, one or more washers 39 may be placed under the bolt head within the countersink, as shown in the drawing, andv this not only provides for adjustment of the device to a thinner glass but prevents increasing. the inner thickness of the a stud extending wit in thimble, a turning device adjustably en-v apparatus becauseby this means the inner end of bolt 39 is drawn toward the surface of the glass and kept at the smallest possible distance therefrom, thus preventing interference with the window frame by any part of the cleaning appliance.

Various modifications may evidently be made without departing from the spirit of -my invention.
