Application. filed November 14, 1929. 1 Serial No. 407,236.

This invention relates to an improved implement or device which is expressly des1gned for cleaning glass, especially W111- dows, show cases, show windows and the In accordance with my conception, I have evolved and produced a novel structural organization of parts cooperating in producing a device including a self-contained water re-- ceptacle, a distributing spray head carried thereby, means for pumping the water under.

cially conducted distributing and spraying.

head carried by the upper end of the handle, whereby to permit the water to be'sprayed against the window. according to the will of the user and to be subsequently scrubbed or wiped therefrom by the rubber squeegee strip, the latter being mounted on said head.

Another feature is found in the incorporation in the head of a regulating valve for intermittently controlling the How of water, together with an operating device which is mounted on the handle within convenient reach of the operators hand to facilitate manipulation of the valve as desired.

in the drawings: l V ..Figure 1 is a front elevational view of a device. constructed in accordance with the present invention.

Figure 2 is a side View with the upper portion broken away and shown in section to show the relationship of elements.

Figure 3 is an enlarged'fragmentary sectional view showing the hand pump and its mounting. v

The handle 4 is in the nature of a tube having the additional function of a water containing cylinder. The head is attached to the upper end of the tubular handle, the head being generally designated by the nu ineral 5. The head comprises a casting in cluding a screw threaded cap 6 threaded on the handle-and including a laterally oflset neck 7 in which a rotary plug valve 8 is located. The neck joins to the head proper as indicated at 9 and the latter part of the structure includes a water containing passage 10 and a multiplicity of longitudinally spaced jets or ports 11 which communicate with the passage. The passage 10 in turn communicates with the cylinder 4 through the medium of the valved duct 12.

In this way the water is let into the head when the valve is open and is distributed in the passage 10 and sprayed out in ets through the ports 11 against the window glass. Projecting out beyond the terminal of the ports 11 and fastened to the lower portion of the head is a rubbers'trip 13 whose length is coextensive with that of the head and which functions as ,a squeegee in a well-known manner.

The fact is, since the rubber strip projects beyond the ports 11 it functions somewhat as. a collection apron to. in distributing the water'in a flowing manner over the sur-. face of the glass. Below the head andon one side, the handle is formed with a filler neck having a closing plug as at 14. The water is placed into the handle by this means.

Formed integral with the casing and depending concentrically intothehandle is the water deliverypipe 15. The pump is mounted in the bottom portion of the handle. 'It is of the hand-manipulated type and comprises a relatively small cylinder 16 carried by the bottom closing cap 17. The cap. includes .a. screw-threaded rim 18 which is threadedion the handle as seen in Figure 3. In addition,'it includes a vent as at 19. A piston is :slidable in the cylinder and includes a head QOand an operating'stem 21 having an externally arranged finger grip as at 22.

,At the upper end of the cylinder is a pro-, jecting nipple 23 providing a cage for a spring, seated check valve 24. Extending from this nipple is an air delivery line whose upper end is located in close spaced proximity to the head to deliver the air into the upper portion of the handle and force the air column downwardly against the water column to lift the water column up through the pipe 15.

The means for operating the aforesaid valve 8 comprising a pivotally mounted lever- 26 as seen in Figure 1 which is connected through the medium of an operating link 27 with the valve. This permits the valve to be opened intermittently as desired by the user.

In practice, the plug 14 is removed and the handle is substantially filled with water. At this time the valve 8 is closed. Then the plunger of the pump is manipulated in a well known manner to build up a quantity of compressed air in the upper portion of the handle to force downwardly on the water column and to lift the water column up into the pipe 15-. Then as the valve 8 is gradually opened, the water is fed through the duct 12, into the passage 10 and distributed against the window through the medium of the multiplicity of discharge ports 11. These streams of water play against the window surface in a forcible manner for effectively removing dirt and dust from the glass.

Then the valve is opened and closed during this action as desired, and whenever necessary, the squeegee 1.3 is brought into play for wiping the water off of the glass in an obvious manner.

It will be understood that the gist of the invention is in the provision of a pump equipped self-contained water handle and a distributing head, together with the valve and operating means, and the complemental squeegee.

A careful consideration of the description in connection with the drawings, will enable the reader to obtain a clear understanding of the construction, operation, and features and advantages of the invention. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size, materials, and re-arrangement of details coming within the field of invention claimed may be resorted to in actual practice if desired.

1 I claim:

1. In a cleaning device of the class described, an apertured delivering and distributing head, and a hollow elongated handle carried by said head, said handle being a water container communicating with said head having a force feed means including an air passage incorporated in its lower end to eject the water, a regulating valve in said head, and an operating lever on said handle and an operating connection between said lever and valve.

2. In a cleaning device of the class described, a tubular handle adapted to function as a container for water, a force fee-d air pump mounted in the lower end portion of said handle, a head structure including a casting having an integral water delivery pipe depending into the interior of said handle and reaching substantially to the bottom of the water container, a head retaining cap removably fitted on the upper end of the handle, and an offset apertured distributing head projecting beyond said cap and in communication with said delivery pipe.

3. In a cleaning device of the class described, a tubular handle adapted to function as a water container and having a force feed air pump mounted in the lower end portion of said handle, a head structure including a casting having an integral water delivery pipe depending into the interior of said handle to a point near its bottom, a retaining cap removably fitted on the upper end of the handle, and an offset apertured distributing head projecting beyond said cap and in communication with said delivery pipe and retained in position by said cap, said head including a regulating valve, a distributing passage for the water, and a multiplicity of jet-forming ports communicating with said passage, a squeegee mounted to project beyond the face of the working edge of the head immediately below said multiplicity of ports.

4:. In a cleaning device of the character described,.an apertured distributing and delivery head, comprising a casing having a longitudinal water containing passage coinmunicating with a multiplicity of longitudinally spaced parts, a squeegee mounted immediately below said ports and adapted to be contacted by the water from said ports as it issues therefrom, a manually operable rotary plug valve in the water passage of the head to control the flow of water thereto from the reservoir, and suitable means to operate said valve from the other end of the handle, a hollow tubular handle attached to said head, a laterally offset neck connecting said head and handle portion having a passage therein to convey fluid from the one to the other, said hollow tubular handle forming at its upper end a. reservoir for water and at its lower end a force pump providing air pressure which is operable to expel the water in said reservoir into the head for delivery and distribution.

In testimony whereof I afiix my signature.

THOMAS C. HOMILLER.
