WINDOW-CLEANING nnvron.v

cars, the windows of engine cabs land 1n similar positions.

The object of the invention is to provide means whereby rain, snow or otherv accumulations may be quickly and easily removed from the exterior of the window and the window itself quickly dried.

To this end it is a further object of the in- 'vention to provide a plurality of sashes so arranged thateither of them may be moved into position to close the window opening and the other moved into an inoperative position, preferably into 4 a pocket in the frame of the car;.also to provide means whereby the movement of one of the sashes into the pocket in' the frame will cause the accumulations of rain, snow or the like toI be removed from the exterior thereof; andalso to provide means whereby the glassmay be dried while the sash is in its inoperative position.

In the accompanying drawings, Figure 1 is a perspective view of the exterior of a window equipped with my invention; Fig. 2 is a vertical section, takenfthrough such a window and showing the. connecting devices between the two sashes;` and Fig. 3 is a sectional view taken through one of the wipers.

In these drawings I have illustrated one invention and have shown the same as applied to the front window of a street car vestibule, the wall of which is indicated at 1 and the frame of the window at 2. Mounted in the window frame are two sashes, 3 and 4, either of which when in its uppermost position will close the window opening. T beneath the window opening is provided with a pocket 5, into which either sash may be moved. The two sashes are preferably connected one to the other so that as one is moved upward the other will be moved Spec'i'cation. of Letters Patent.

downward and the act of moving one will impart movement to the other. In the present instance this connection is formed by means of sprocket chains 6 and 7. Each sprocket chain y6, of which there are preferably two, extends about a sprocket wheel 8 journaled in a suitable housing 9 mounted .in the upper. part yof the window frame, and

is connected at its ends to the upper edges of the two sashes.- Each of the other sprocket chains 7, of which there are also two, extends about a sprocket wheel 10 journaled in a similar housing 11 mounted in the frame of the car near the bottom of the pocket and is connected at its ends to the lower edges of the two sashes. Suitable wipers are arranged to remove the moisture from the glass of each sash as it is moved downward. In the present instance, these wipers are in the form of squeegees 1Q and 13, the squeegee 1:2- being mounted upon the window sill and arranged to engage the glass of the outersash 4f when the latter is moved downward. The squeegee 13 is mounted upon the top of the sash 4 and will engage the glassV of the' sash 3 as Ithe two sashes move relatively one to the other, thus wiping the moisture from the exterior of the glass of the sash 3. These squeegees preferably engage the glass with a yielding pressure and to this end each is movably mounted upon its supporting structure and is held in engagement with the glass by means of a spring. As here shown the window sill has formed therein, near each end thereof, a recess in which is mounted a housing 14 having'its upper end open. The squeegee 12 is provided with a depending lug 15 which extends into lthe housing 14 and has an aperture through which a pin 16 loosely extends; This pin lvextends through the outer end of the housing and is screw-threaded into the inner end of the housing. The ends of the pin extend through the adjacent portions of the windowsill, or sash as the case may be, and serve to'hold the housing in position. A. spring 17 is coiled about the pilr 16 between the lug 15 and the outer wall of the housing and tends to move the squeegee toward the window. By'removing the pin 16 the squeegee can be removed and renewed when the flexible or wiping portion thereof becomes worn.

It will be apparent that with the construction above described each sash may be cleaned by the mere act of moving the same downward into an'inoperative position and that this act will simultaneously move the other sash into operative position. By'providing the squeegees with suliicient exibjlity they may be used with sash of ordinary construction but to. enable them to more readily pass the ends of the sash I prefer to mount the glass substantially flush with the face of the sash. In the present instance this is accomplished by securing the glass in place by the use of thin metal strips 20.

It is desirable that meansshould be provided to dry the glass of the sash which is in lthe pockety 5 and to this end I mount within the pocket 5 a suitable heater which, in the ,present instance, is shown as comprisinga radiator 18 having la series of-coils the sashes to be frequently shifted from one position to the other and a clean dry Window provided at fre uent intervals; It will also be noted that t e wipers or mops extend beyond the edges of the glass vand have re` silient or felted vportions engaging the sash on the opposite sides of the glass, thereby constituting weather strips and eiectually what I claim as new preventing theentrance of cold air. into the car through the window frame. l

While I have shown and described one embodiment of my linvention it will be understood that this has been chosen for the purpose of illustration only land that I do not desire to be limited to the! details of construction shown and described, except as limited by the appended claims for obvious modifications will occur to a person skilled in the art. l .y v
