o water from the sponge which is wiped from the pane with the squeegee and runs down over the window sill.

The above disadvantages are overcome by.`

the device of my invention in accordance with the general features of which I provide a selfcontained unit in which the use of an excessive amount of water is avoided.

An object of the invention is to provide a new and improved window cleaner.

A further object is to provide a compact, self-contained unit having a wiper, a cleaner, and a. supply of cleaning fluid.

A further object is to provide a cleaner which is rugged in construction and inexpensive to manufacture.

A further object is to provide a cleaner which does not require wetting the hands.

A further object is to provide a cleaner which avoids the excessive use of water.

Other objects and advantages will appear as the description proceeds. Y s

Referring to the drawing, Fig. 1 is a plan view of the window cleaner embodying my invention, Y

Fig. 2 is a section taken' on line 2-2 of Fig. 1, and,

Fig. 3 is a section taken online 3-3 of v Fig. 1.

rIhe device comprises in general, a head 9, and a handle 11. The handle comprises a hollow tube 12, which is threaded at its upper end to receive a threaded cap 18, rigidly secured to the head. A-stopper 14, is placed in the hollow tube a suitable distance from the top to form a chamber which serves as a reservoir for a cleaning fluid.Y The lower end of tube 12 is adapted to receive a rod or extension handle 15 of suitable length toY Vpermit the userto reach all parts of a window. The head consists of an upper plate 16 and lower plate 17, having a substantially rectangular wiper of rubber or other suitable vresilient material clamped therebetween. An absorbent cleaning strip or wiper 19 is clamped between "the opposite side of the plates. y The strip 19 is 'made considerably thicker than wiper 18, and the upper plateis provided with an offset portion 2l, to accommodate the thicker cleaning strip. Ther rub'-v ber 'wiperv 18 has a cut-outfportion 22 inthe portion'which isclamped between the plates, leaving a longitudinal chamber extending substantially the length of the plates. The

vends 23`of the rubberl wiperare left intact to closeythe ends'of the chamber, andprevent the cleaning fluid from escaping. The lower plate 17 is provided with an aperture, the rim of which is crimped over a similar aperture Y in cap 13 for securing the cap to the plate,

and at the same time providing a duct 25 interconnecting the chamber with the reservoir. It will be noted that the chamber eX- tends along substantially the entire length of the cleaning strip 19. However, on account of the close spacing of the plates forwardly of the cleaning strip only a small portion of the edge of strip 19 is in communication with the chamber. In order to increase the area of contact between the cleaning fluid and the cleaning strip, a pluralityv of beads 26, are formed in the upper plate 16, which provide cavities 27 for increasing the area of Contact between the cleaning strip andthe cleaning iiuid.

In using the apparatus it is preferable to first wet the cleaning strip 19 by dipping it in water or other suitable cleaning fluid. The reservoir in the handleis then filled with the cleaning fluid and the device is ready for use. On account of the movement of the device in use, the cleaning fluid will, from time to time, be applied to the cleaning strip 19 to keep it moist. The cleaning strip'is first wiped over the surface of the window to be cleaned to loosen the dirt and' just sufficient water is supt plied to permit the dirt to be wiped from the window by the rubber wiper or squeegee. VIn this way any excess of water-'is avoided which would otherwise be wiped to the lower edge of the window and run over the window sill.

The device obviates the necessity of wetting the hands in order to wash the windows, and adds greatly to the convenience and sanitation of window washing.

It will be understood that the embodiment of the invention herein described and illustrated is merely illustrative of the invention and that many modifications may be made therein Without departing from the spirit and scope of Vthe invention.'

What I claim is new and desire to protect by Letters Patent of the United States is A window cleaning device comprising a hollow handle serving as a reservoir for a cleaning fluid, a head mounted on the handle and consisting of an upper and lower plate', an absorbent cleaning strip clamped between the plates and extending Jfrom one side thereof, the upper plate having an oiiset portion to accommodate the cleaning strip, a plurality of beads in said oil'set portion forming fluid cavities adj acentthe edge of the cleaning strip, the lower plate having an aperture ,extending into the reservoir and forming a fluid passage between the reservoir and the absorbent cleaning strip to keep the strip moist with the cleaning fluid.

In witness whereof, I hereunto subscribe my name this 29th day of November, 1929.

SAMUEL FLEISCHMAN.
