3 Glaims.

The present invention relates to an attachment for use in connection with washing machines and the like, and has particular reference to a faucet connection and conduit system adapted for use with dishwashing machines.

A primary object of my invention is the provision of a faucet connection which may be removably attached to a faucet.

An additional object is the provision of a faucet attachment for an inlet conduit wherein a detergent material may be inserted in dry form in the faucet connection and be transferred therefrom to the washing machine tank or other receptacle.

These and other objects will become apparent from the following description and by reference to the accompanying drawing, in which Fig. 1 shows a household sink and a dishwashing machine of conventional type connected by means of the inlet and outlet conduit system constructed in accordance with my invention;

Fig. 2 is an enlarged cross-sectional view of the faucet connection made in accordance with my invention; and

Fig. 3 is a cross-section taken along lines 3--3 of Fig. 2.

In the drawing, 1 represents the tank of a dishwashing machine. This tank is suspended in a frame structure 2, and is provided with a motor 3 mounted beneath the tank. The motor serves to drive suitable washing mechanism in the tank, including a centrifugal pump of conventional design (not shown) in chamber 4.

Extending from the chamber 4 is a metal discharge tube 5 to which is attached the lower end of a rubber discharge tube 6. This discharge tube extends upwardly along the side of the tank, through the double brackets '7 and 8, terminating in a downwardly extending discharge nozzle 9.

The tank is provided with an inlet opening into which is compresseda tightly fitting rubber inlet connection 10. The edge of the tank wall which defines the inlet opening is held in a water-tight manner in channel 11 of the plug or connection 10. To the upwardly extending arm 12 of the plug is attached the lower end of a rubber hose or other resilient tube 13. This tube extends upwardly through the brackets 7 and 8 alongside the outlet tube 6.

The bracket '7 is preferably fixed to the rim 14 of the frame structure 2, whereby the inlet and outlet tubes are maintained in definite position with respect to the tank structure. In order to prevent undue distortion of the resilient tubes 6 and. 13, each tube is enclosed adjacent the bracket '7 in a spring 15. It is found that this spring greatly prolongs the life of the tubes and increases their effectiveness.

To the outer end of the inlet tube 13 is aifixed a faucet connection 16. As shown in Fig. 2, the faucet connection has a downwardly extending tubular portion 19 which is inserted within the tube 13;

The faucet connection 16 has a cylindrical chamber 17 which is provided with an outlet opening 18 which communicates with the tube 19. A relatively short distance above theopening 18 the side wall of chamber 1'? is cut away to form a relatively large opening 20.

Resting on the top rim of the chamber 17 are the outwardly flared edges 21 of the funnelshaped tube 22. This tube extends downwardly to a point adjacent the opening 18, and its terminal portion is preferably spaced from the wall structure of the chamber 17 and tube 19. The terminal end of the tube 22 is cut away at an angle as at 23 on the side opposite the opening 20. The tip end directly in front of opening is bent slightly to baifle the water toward the inner side wall of chamber 17 opposite the wall 20.

Positioned above the tube 22 and having its outer edges resting against the edges 21 of the tube is a rubber cap member 24. This cap member has a downwardly extending tubular portion 25 of such size as to form a firm frictional engagement with the discharge end of the faucet 26. A detachable cap 27 is fitted over the rubber cap 24 and is screwed to the outer wall of chamber 17, thereby acting as a securing means to retain the rubber cap member 24 and the tube 22 in position. The faucet is connected in the usual manner to wall 28 of sink 29.

When the faucet connection is fixed to the faucet and water under pressure discharged therethrough, the water passes through the funnel tube 22 at a relatively high rate of speed.

Discharge of the water into tube 19 creates a partial vacuum in chamber 17. Provision of the partially cut-away and bafiled portion 23 causes a small amount of water discharged from tube 22 to be projected into the chamber 17, creating a swirling motion therein. This water does not reach a height sufficiently great to cause it to splash or flow out of the opening 20. In the operation of a dishwashing machine, for example, it is desirable to treat the water with a water-softening agent, or detergent, preferably before the water enters the washing chamber. For brevity, the term detergent is used herein and in the appended claims to denote watersoftening agents, soap and other materials of similar character. In accordance with my invention, the detergent with which it is desired to treat thewater is inserted into the chamber 1'7 through the opening 20. The partial vacuum adjacent the end of tube 22 and a small amount of water in chamber 17, by reason of the cutaway and baiiled portion 23, causes the detergent to be effectively mixed with the water and carried into the tube 19 and conduit 13. The water enters tank 1, properly treated with the desired detergent.

Water is discharged from the tank through tube 6, and as this tube is manually connected to the tube 13 by the bracket 8, it is insured that water discharged from the outlet tube will be directed into the sink.

By means of the conduit system described heretofore, it is possible to move a detachabletype washing machine from a remote position to a position adjacent the sink. The faucet connection 16 is then engaged with the discharge end of the faucet. After the washing operation is completed it is only necessary to detach the faucet connection 16 from the faucet in order to again move the washing machine to a remote position.

Many variations of the structure described heretofore will occur to one skilled in the art andsuch modifications as come within the spirit of my invention are intended to be included in the appended claims.

I claim:

1. In a device of the type described, a casing having an outlet opening in the bottom thereof and a detergent opening in the side thereof communicating with the atmosphere, a faucet connection in the top of said casing, and a tube communicating with said faucet connection and extending downwardly adjacent said outlet opening, the lower end of said tube being cut away on the side opposite said detergent opening.

2. In a device of the type described, a casing having an open top, and an outlet opening in its lower portion and a detergent opening in its side portion, a funnel tube having its upper edges fitted against the edges of the top of said casing and extending downwardly adjacent said outlet opening, a rubber cap having its outer edges fitted over the outer edges of said funnel tube and being provided with an opening for receiving the discharge portion of a faucet, and a securing cap fitted over the outer edges of said rubber cap and threaded to the sides of said casing.

3. A device of the type described, comprising a vertical casing provided with an outlet opening in the lower portion thereof, said casing having an additional opening for receiving a detergent, a

top for said casing having a faucet connection therewith, and a tube communicating with said faucet connection and extending downwardly adjacent said outlet opening, the lower end of said tube being partially baflied and cut away on the side opposite said baffle.
