Application August 6, 1953, Serial No. 372,766

4 Claims. (Cl. 15-126) This invention relates to a window cleaner.

It is the object of the present invention to provide a fluid container, together with a manually operable fluid ejecting device in conjunction with a support upon the container for mounting a sponge and wiping blade.

It is the further object of the present invention to provide a novel and simplified window washer wherein the container itself forms the handle and wherein said handle facilitates the manual ejection of cleaning fluid to the surface to be washed, and wherein there is attached to the handle as a part of the device a sponge and a wiping blade.

These and other objects will be seen from the following specification and claims, in conjunction with the appended drawing, in which:

Fig. 1 is a side elevational view of a window washer.

Fig. 2 is a fragmentary section taken on line 2-2 of Fig. 1.

Fig. 3 is a similar view illustrating a slightly different, preferred form of housing and sponge and blade supporting element.

Fig. 4 is a section taken on line 4-4 of Fig. 3.

Fig. 5 is a side elevational view of a slightly different form of Window washer; and

Fig. 6 is a fragmentary side elevational view thereof, partially sectioned for illustration.

It will be understood that the above drawing illustrates a preferred embodiment of the invention, and that other embodiments are contemplated within the scope of the claims hereafter set forth.

The window washer shown in Figs. 1 and 2 includes the hollow elongated container 11 adapted to store a cleaning fluid, such as water, said container having circular outlet 13 at one end adapted to cooperatively receive the body portion 14 of a manually operable plunger actuating fluid ejector.

Said ejector includes cylinder 15 from which depends fluid intake pipe 16, whose inlet 17 is adjacent the lower end of container 11.

Manually operable plunger 18 with handle 21 adapted to receive the users finger with the same hand grasping the container, is slidably positioned within element 14 and carries piston 19 at its lower end movable within cylinder 15, there being a coiled spring 20 in said cylinder below said piston, normally urging the same upwardly. A conventional type of ball check valve 20' is positioned within cylinder 15 at the lower end of spring 20 normally closing off the internal passage to intake pipe 16.

At the upper end of plunger 18, there is provided a transverse fluid outlet 22 in communication with the interior of pumping cylinder 15 and adapted to spray cleaning fluid or water upon a surface, such as a window, upon manual application to handle 21.

Arranged upon opposite sides of container 11, towards its upper end and extending above, are a pair of

cylindrical extensions

23 and 24, centrally and longitudinally apertured at 25, adapted to cooperatively receive the lower ends of the pair of upright wire supports 26.

The upper ends of said supports are adapted for securing to the clamp 28--29, which retains upon its opposite sides the opposed parallel transverse elongated sponge 30 and rubber wiping blade 31. The upper ends of the wire supports 26 are outturned at 27 to supportingly bear against the undersurface of clamp element 28. Elements 27 terminate in the upwardly extending portions 32, which extend through apertures in clamp 2829 with the outer ends 33 grippingly engaging over the top portion of clamp element 29 for completing the window washer construction.

The elongated formed sponge 3G is of a conventional type and lies in a plane at right angles to the longitudinal axis of container 11. I

The advantage of the present structure lies in the fact that using the container 11 as a handle and with one finger engaging plunger l8-21, fluid may be sprayed upon the window surface to be cleaned, such as any of the windows of a vehicle, and immediately thereafter the sponge 30 may be applied to the surface, followed by application of the wiper blade 31. This provides a very convenient way of directly applying cleaning fluid and thereafter washing and wiping without laying the device down, as is the case where the fluid container is separate from the sponge and wiping blade.

Another advantage to the present construction lies in the fact that this device can be stored in the glove compartment of a vehicle, so that it is available for use at any time.

The variation in structure shown in Figs. 3 and 4 contemplates the use of an elongated fluid container 34, having a central aperture 35 at one end adapted to receive the same manually operable plunger actuating fluid ejector or pump above described in connection with Fig. 2.

Arranged upon opposite longitudinal edges of container 34 are a pair of opposed elongated indentations 36 adapted to cooperatively and retainingly engage the wire supports 37, which are formed in U-shape and which terminate at their outer ends in the clamp engaging elements 38 bent outwardly at right angles to wire support elements 37.

The sponge 30 and wiper blade 31 as retained by the clamp 28-29 of Fig. 1, may likewise be applied to the wire supports 37 and 38, in the same manner as the wire supports 26 of Fig. 2 are applied to said clamps.

Figs. 5 and 6 show a slight variation in the present structure, wherein there is provided an elongated fluid container 39 open at its upper end, but covered by a centrally apertured cap 40, which is adapted to cooperatively receive and retain within such aperture the body portion 14 of the manually operable plunger actuating fluid ejector or plunger of the same construction as above described in connection with Fig. 2.

A sponge and wiper blade support of cylindrical shape 41, and with a slightly inward taper towards its outer end, is provided. Said support is transversely and oppositely slotted as at 43 and 44, permitting manual access to plunger handle 21, and at the same time providing for the cylindrical, slightly tapered mounting ring 42, which cooperatively extends over and retainingly engages, as by friction, the cap 40 on container 39.

The upper end of support 41 has a second circular portion 45 from which upwardly extends the supporting element 46, whose upper ends are outturned as at 47.

Support elements 47 bear against the undersurface of clamp element 48, and outer portions of elements 47 extend upwardly through corresponding apertures in both clamp elements 48 and 49, and are outturned as at 52 for securing the clamp elements together and for retaining within said clamp elements the elongated parallel transversely arranged sponge element 50 and the opposed wiping biade'Sl,'as'illu'strated'in"Fig. 5.

While the above drawing jillustrates a preferred embodiment of the present invention, it is contemplated that theremay be'm'aniyother structures adapt'ed'tb carry out the present invention, and within the scope bf th'e claims hereafter set forth. v v
