WINDOW CLEANER.

Application filed March 14, 1924. Serial No. 699,201.

To all whom it may concern:

Be it known that we, WILLIAM R. TURNER and AARON V. SNEDEKER, both citizens of the United States, and residing, respectively, in Newark and East Orange, county of Essex, and State of New Jersey, have invented new and useful Improvements in Window Cleaners, of which the following is a specification.

This invention relates-to improvements in devices for cleaning windows and like smooth surfaces, usually vertical and frequently at a considerable height above the level on whichthe operator stands.

The principal object is to provide an effective form of squeegee or wiper, carried rigidly at the end ofa pole handle of convenient length.

Another purpose is to produce a combined moistener and scrubber having a liquid supplying reservoir rigidly attached to the handie in proximity to the wiper.

A further aim is in the provision of an eflicient and practical apparatus, taking the place of two or more separate devices, and in which the contacting elements are readily renewable as they become worn.

These and other analogous aims, objects and purposes are accomplished by the novel construction and arrangement of parts here inafter described and shown in the accompanying drawing, forming a material part of this disclosure, and in which Figure 1 is a perspective view of an embodiment of the invention as fully assembled ready for operation.

' Figure 2 is -a transverse sectional view taken through the center of the same.

Figure 3 is a perspective view of the com bined moistener and scrubber element, shown in a reversed position.

Referring more in detail to the drawing, the numeral 10 designates the pole or handle bar, which may be of any desired length to enable an operator to conveniently manipulate the apparatus, and is shown as tapered at one end to receive a slightly conical ferrule 11.

The extending end of the ferrule is cut away, as at 12, and the remaining metal flattened to produce a plate 13, to which is rigidly secured an elongated, substantially U-shaped spring clip 14 suited to engage and maintain a doubled strip of rubber sheeting 15 or its equivalent, the same constituting a squeegee or wiper.

F ixed on the outer end of the ferrule 11, back of the recess 12, is a reservoir 16, the same preferably having upwardly converging walls at its sides 17 and ends 18, presenting a cross section substantially in the form'of an isosceles triangle, one of the ends being provided with a filling spout 19 hav ing a removable cap 20.

Said reservoir is of a length commensurate with that of the wiper 15 and of suitable. width; its lower edges are expanded or offset outwardly, as at 21 and 22, forming a shallow bevelled socket.

A block 23, preferably of wood as'sh wn. isdim'ensioned and bevelled to fit the socket, said block having in its lower surface a series of longitudinal grooves 24 and bet-ween these grooves are a plurality of openings 25 through which liquid in the reservoir may readily pass.

Enveloping the face, side and end edges of the block is a casing 26 of felt or other thick fabric constituting a pad, its edges eX- tending over the top of the block, so that when the encased block is fixed in the bottom of the reservoir, as to receive the liquid and conduct it, by capillary attraction, to the outer contacting surface, the central portions of which are moistened by liquid passing through the openings 25.

This felt covering 26 is carried into the grooves 24: and held by small tacks 27 or their equivalents, as are also its inner edges, and in addition, the covering is further secured by contact between the bevelled edges of the block 23 and socket elements 21 and 22 of the reservoir, the block being removably engaged in the socket by screws 28.

In operation, the reservoir having been supplied with any preferred cleansing solution or plain water, the cushion-like scrubber becomes moistened immediately and can be applied by meansof the handle bar to the window pane or other surface to be cleaned.

As the action is transverse to the grooves 24:, they act to gather and retain dirt particles, while the raised portions dispense moisture and act to effectively scrub the surface.

By turning the pole half way round the wiper 15 is brought into operation, removing the water and giving a final polishing ef-' feet.

It is to be noted that the wiper is readily renewed and also the covering 26 can be replaced by removing the screws holding the block in the reservoir.

It may be further remarked that due to the weight of the reservoir an effective pressure is provided which materially augments the desired effects and without noticeable effort 0r fatigue on the part of the operator.

From the foregoing description, taken in connection with the accompanying drawing, the invention will be readily understood and it will be apparent that changes in the form, proportions and minor details of construction may be made without departing from the spirit of the appended claims.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is

1. A window cleaner comprising a handle bar, a reservoir rigidly carried on said bar, said reservoir being of triangular cross section, a perforate block removably engaged in the base of said reservoir. said block having a series of longitudinal grooves in its lowersurface, and a scrubbing pad of textile fabric covering the bottom andedges of said block, said pad conformably lining the mentioned grooves.

2. A window cleaner comprising a handle bar, a tapered ferrule rigid on one end thereof, a reservoir of triangular cross section fixed onsaid ferrule, means for filling said reservoir, a rectangular socket formed by expanding the base edges of said reservoir, a perforate block engageable in said socket, means for removably securing said block therein, and a fabric covering for said block.

A window cleaner comprising a handle bar, a tapered ferrule rigid on one end thereof, a reservoir of triangular cross section fixed on said ferrule, means for filling said reservoir, a rectangular socket formed by expandingthe base edges of said reservoir, a perforate block engageable in said socket, said block having a series of parallel recesses in its lower surface intermediate the perforations, a fabric cover extending over the lower surface of said block and including its edges and grooves, and means for securing said block and casing in said socket.

This specification signed and witnessed this 22nd day of December. 1923.
