United States 3,009,190 HAND WASHER Alfred E. Awot, 1048 N. Christiana Ave., Chicago, Ill. Filed Nov. 27, 1959, Ser. No. 855,841 9 Claims. (Cl. 15-524) This invention relates in general to a hand washer of the fountain cleaning type particularly desirable for dishwashing, car and window washing with or without the addition of a detergent.

An important object of the invention is to provide a washing, scrubbing and cleaning device which may be used to wash dishes, windows and even automobiles and other articles by a direct manual application which will etiiciently wash and clean the articles or surfaces washed by separately applying a detergent if desired which is fed selectively in a new and efficient manner through the washer whenever desired.

An important object of the invention is to provide a hand washer in which a cleaning material of sponge rubber and the like may be removably applied and attached to the outer surface of the washer.

A further object of the invention is to provide a hand washer having separate water and detergent releases easily operated by the lingers of one hand;

A still further object of the invention is to provide a hand washer with a removable sponge or cleaning device, of a size which may be inserted within an ordinary glass or tumbler for dishwashing.

Still a further object of the invention is to provide a hand washer having a cleansing pad surrounding the greater portion of the outer surface and projecting at one end thereof to overlie a scraper which may be separately applied at the end for cleaning and removing materials from dishes or other articles as they are being washed.

Other objects of the invention will appear in the specilication and will be more apparent from the accompanying drawings in which,

FIG. l is a top view of a hand washer in accordance with this invention.

FIG. 2 is a longitudinal section of the washer as shown in FIG. 1; and

FIG. 3 is an end view of the discharge end of the washer.

In dishwashing and similar `cleaning apparatus which utilizes a liquid detergent or cleanser, it is common practice to discharge a small amount of the detergent continuously into the owing liquid. In the present invention, the washer is provided with a cleaning pad which surrounds a circular support and is removably secured thereto and the detergent is discharge directly into the pad rather than into the cleaning water or at the end of the washer.

Referring now more particularly to the drawings, the washer comprises a tubular outer shell preferably made of plastic but also may -be made of thin metal or other suitable material, one end of which has a wavy or corrugated part forming a handle 12, adapted to provide an improved inger grip for holding and applying it. At the inside of the shell 10 is a water tube 14 which is connected Y to an inwardly turned end portion of the handle and is provided with an inner threaded portion 16, into which a plug 18 is inserted which has a central water passage and an outwardly projecting stem 20 for the connection of an attachment hose 2.2 held in place by outer ribs 24 on the stem or any other suitable hose clamp and having a loose surrounding spiral spring 26 engaging in the end recess of the handle and extending outwardly beyond the stern for ypreventing a localizing of the bending of the hose at the end of the stem 20. The outer end of the hose is commonly provided with an enlarged end 28 with a washer 30 therein for quick frictional attachment to the end 3,009,190 Patented Nov. 21, 1961 of a faucet, or by threading it to the end of an ordinary garden hose, and the like. Thus the washer may be attached by its relatively short hose 22 for washing dishes and may be attached to a longer section of garden hose for washing a car, house windows and the like.

Inwardly from fthe handle end of the water tube 14 is a transverse partition 32 with a valve opening 34 therethrough. A valve 36 is located at the outer side of the partition with a stem 33 extending loosely through the partition and inwardly thereof, the valve being seated against the outside of the partition or against a washer 40 surrounding the stern at the inner side of the valve between it and the partition to make a fluid-tight joint.

In the wall of the water tube 14 inwardly from the partition 32 is a small circular chamber 42 having a wall at the inner end with a perforation 44 therethrough and a cap 46 threaded on the other end of the chamber with a perforation 48 therethrough. Seated in this chamber is a valve operator for engaging the stem 38 and comprising an operating stem 5t) of a size and length to extend through the perforations 44 and 48 and beyond the end of the chamber and its cap 46. Near the outer end of this stem 50 is a projection 52 preferably in the form of a nut ordisc secu-red to or formed integral with the stem and a spiral .spring 54 surrounding the stem and pressing against the inside of the bottom of the chamber presses against the inside of the projection 52 tending to hold the stem 50 in a position with both ends projecting from the chamber.

In the outer wall of the handle opposite the location of the chamber 42` is a preferably ilat iiexible portion 56 with a contact portion 58 adapted to engage the outer end of the stem 50 when the stem is pressed outwardly by its spring 54. On the outer side of the flexible portion 56 is a knob 60 or a raised portion for lengagement by the finger or thumb of an operator so that by pressing the VVflexible portion inwardly, the valve operating stem 50 may .be depressed sufficiently to engage the stem 38 of the water valve 36 and to move the valve suiciently to open it for the admission of water from the hose connection to the water tube 14. The valve 36 is normally seated against its valve opening 34 by the pressure of water through the hollow stem 20 and even if there is no water pressure, the valve is held against `displacement by the inner end of the plug 18 which is spaced slightly from the outer side of the valve 36 and suiiiciently to allow it to be rocked to open position by the said movement of its stem.

Surrounding the water tube 14 and between it and the outer shell 1t) is a detergent chamber 62 closed at the handle end of the washer, but having a closing plate 64 at the outer end in the vform of a circular ring extending between the outside of the water tube and the vinside of the outer shell 10 and preferably at a short distance inwardly from the outer end of the shell. In this plate is a detergent till opening 66 somewhat curved and conforming to the shape yof the plate and having a closure plate 68 with an opening 70 corresponding to the till yopening and movable to register with the opening 66 or to form a closure therefor when desired. To operate the closure plate, it is prefeably formed opposite ears or projections 72 having outside threads to engage with inside threads 74 at the inside of the shell 10 near the end thereof, The closure plate 68 may therefore be moved for filling and closing the detergent chamber as desired.

vVlhe end of the water tube 14 may be -left open or it may be provided with a spray nozzle 76 having a hollow stem extending into the outer end of the water tube 14 and either separately threaded into the water tube or secured in place by the engagement of inner surfaces of the projection 72 with the outer side of the nozzle con- 3 ning the stern thereof against the inside of the closure plate 68.

That portion of the outer shell from the handle 12 to the outer end thereof is preferably circular and slightly reduced in diameter to receive a pad 80 of cleaning material preferably of sponge or plastic sponge-like material which is wrapped around the Washer and is of a length to substantially lill and cover the entire outer circular surface with the ends substantially abutting at the upper side thereof where they are secured in place by a clamp 82. This clamp may be of the same material as the washer, or it may be of metal and has downwardly turned serrated edges 84 which are moved against the outer sides of the abutting portions of the cleaning pad. The outer surfaces of the shell may also be formed with longitudinal ribs 86 which may also be toothed or serrated in order to hold the sponge or pad 80 more closely in place. The clamp 82 has a hinge 88 at the handle end for rotatably securing it to the handle and the opposite outer end of the shell has a projection 90 with an oblong turned button 92 pivoted therein. The end of the clamp has a longitudinal slot 94 through which the button 92 will pass so that when the clamp is moved downwardly, engaging the adjacent edges of the celaning pad and the button inserted through the slot, the button may be turned at right angles as shown n FIG. l for locking the clamp in the downward position and for holding the sponge or pad in position.

At the lower forward edge of the shell 10 is a ange 96 which projects outwardly beyond the adjacent edge of the sponge or pad 80 forming a projection or scraper for cleaning dishes and the like, assisting to retain the pad in place.

In order to apply detergent to the sponge or pad 80, one portion, preferably the bottom of the washer as shown in FIG. 2 is formed with a number of feed holes 98 which provide passage from the detergent chamber directly into the pad 80 and a valve plate 100 is positioned at the inside of the shell 10 having rivets 102 or other suitable fastening means for securing one end of the plate to the inner wall of the shell and having projections 104 which normally seated to cover the feedholes 98. At the other or free end of the valve plate is a boss 106 in the adjacent end of the handle 12 through which is a perforation 108 for seating a push rod 110, the inner end of which normally engages the free end of the valve plate and the push rod is pressed outwardly thereby freeing the outer end of the push rod for a limited inward movement. By pressing the push rod inwardly, the valve plate 100 raises its projections 104 from covering the feed holes 93 and liquid detergent is discharged from the feed holes in accordance with the openings thereof.

With this construction, it is a simple matter to apply a sponge or pad to the reduced portion of the outer shell, to swing the clamp 82 upwardly about its hinge 88 to insert the abutting ends of the pad under the clamp and to engage the abutting ends with the clamp when it is turned downwardly and to secure the pad in place by means of the turned button 92. The shell is preferably of a size such that the cleaning pad may be inserted in ordinary glasses or tumblers for washing the insides thereof, of the end of the pad projections beyond the end of the washer so that dirt in a glass or on dishes may be dislodged by the scraper ilange 96 and may be contacted by the projecting end of the sponge outside of the flange.

The flow of water through the washer is easily controlled for continuous operation simply by a constant pressure on the knob 60 and at the same time, the flow of detergent therefore may be constantly or intermittently controlled by the thumb or ngers of the same hand which grasps the handle. The projecting knob 60 may be engaged even by the palm of the hand or by the thumb or finger thereof at the same time some other nger engages the push rod 110 of the detergent valve.

The outer surface of the cleaning pad projects substantially ush with or slightly beyond the confines of the handle 12 so that the washer may be used for engaging windows, washing walls and automobile sides as well as irregular depressions or portions thereof.

While a preferred construction has been described in some detail, it should be regarded as an illustration or example rather than as a limitation or restriction of the invention, since various changes in the construction, combination and arrangement of the parts may be made without departing from the spirit and scope of the invention.
