? ATTORNEY.

INVENTOR.

Patented Aug. 8, 1939 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to a combination windshield and window-cleaner and has for its object to provide a combined wind-shield and window-cleaner which will be simple in construction, cheap to manufacture, efficient in its working, and exceedingly durable.

My invention consists of certain novel features and details of construction, as will be more fully described hereinafter and finally pointed out in the claim.

With these objects in view I will now describe my invention reference being had to the accompanying drawing in which similar letters of reference indicate corresponding parts, and in which Figure l is a front elevation partly in perspective of my improved wind-shield cleaner as it appears completely assembled.

Fig. 2 is a similar view of the revolving blade, removed from the case.

Fig. 3 is a View of a modified form of blades, showing a strip of felt secured therein and running lengthwise thereof.

Fig. 4 is an end elevation of the cleaner proper as it appears looking at it from the lower end of Fig. 1.

Fig. 5 is a transverse sectional view of the revolving blades, taken on line of Fig. 2.

Fig. 6 is a similar View of the revolving blades, taken on line 2-2 of Fig. 3, better showing the felt strip contained within said blades.

Fig. 7 is a side elevation of the window-cleaner, which is of the same general construction as Fig. 1, with the exception of a handle for manipulating same.

Fig. 8 is a side elevation of the spring employed for holding the wiper in close proximity or contact with the windshield glass.

Fig. 9 is an end elevation of the same.

Fig. 10 is an end elevation of the windowcleaner shown in Fig. 7.

Fig. 11 is a side elevation of the wind-shield cleaner, showing the boss for connecting the cleaner proper to the operating arm or lever from the vacuum cylinder or electric operating device, and

Fig. 12 is a transverse sectional view of the same, taken on line 33 of Fig. 11.

A detailed description of my invention is as follows: i

A represents the case of the wind-shield and window-cleaner, which is semi-circular in form and is provided with flanges B, on both open edges and is enclosed at both ends C, each of which is provided with holes, into which is mounted the revolving blades D. These blades are cast or moulded from rubber upon a core of wire E, which runs through the entire length of the blades D, and project a suitable distance beyond each end thereof, and are threaded, the purpose of which will appear hereinafter.

The revolving blades D are formed in the shape of corrugations out of one piece of rubber and are so arranged, that at least two of these blades come into contact with the glass at the same time, thus presenting a definite cleaning sur face for removing rain and snow from the windshield or window-glass.

The revolving blades D are mounted in the case A, at each end thereof, and are held in a rigid position by means of thumbnuts F. When it is desired to change the position of the blades, the thumb-nuts are loosened and the blades revolved or moved to a different position. This only becomes necessary when the blades in contact with the glass become worn.

A boss G is formed on or secured to the back of the case A, and is provided with a hole H, for connecting the cleaner proper to the operating arm or lever I, of the vacuum cylinder or other operating device.

A tongue J is cut from the back of the case A, and adapted to be bent into such position as to embrace the operating arm or lever, the purpose of which is to steady the cleaner when working, thus preventing a wiggling motion on the glass. This tongue J is best shown in Figs. 10 and 11.

In the modified form of revolving blades, I have shown one of the rubber blades removed and a strip of felt K, inserted in its stead, the purpose of which is for absorbing and containing an antifreeze solution, to prevent ice forming on the Wind-shield.

On the shaft L, which runs from the vacuum cylinder or other operating device, I have provided a spring M, having a hub N, which fits over the end of said shaft and through which the operating arm or lever passes and is held in position on said shaft L, by any suitable and convenient means, preferably by a cotter-pin, (not shown). The lower portions of the spring M, is broadened out as best shown at 0, Fig. 8, and is adapted to engage the operating arm or lever for the purpose of exerting tension on said arm or lever, which in turn holds the cleaner more firmly against the glass.

In the modified form of cleaner shown in Figs. 7, and 9, I have shown the case of the cleaner provided with a socket P, into which is secured an ordinary handle Q. This form of cleaner is intended for use in cleaning windows. The handle and socket being the only innovation from the wind-shield cleaner as shown in the several other figures of the drawing.

Having described my invention, what I claim and desire to secure by Letters Patent is:

A window cleaner, consisting of an elongated semi-circular case into which is journalled a shaft upon which is mounted a rubber wiper body having a plurality of wiping edges integral therewith and disposed longitudinally of and spaced about the periphery thereof, means to hold said shaft in a rigid position within the case, and means connected to the case for moving same over a surface to be wiped, all substantially as shown and described.
