DISHWASHER.

Application filed February 10, 1926. Serial No. 87,222.

Our invention relates particularly to dish Washers.

The main object of our invention is to provide a convenient liquid mixer adapted to be connected to water pipes or to other sources of liquids under pressure. Another object is to provide convenient means for the washing of any articles which may be cleaned by the application of liquids, .for example, the washing of dishes with a mixture of Water and liquid soap. Another object is toprovide convenient means for tempering water and mixing soap with it when desired.

The preferred form of our invention comprises a rigid container having a flexible receptacle Within it. entrance of a liquid under pressure within the container to compress the inner receptacle. Both the container and the receptacle are adapted to discharge into a common chamber which is formed so as to accelerate the mixing of the liquids.

Fig. 1 is a front view of one form of a liquid mixer embodying our invention.

Fig. 2 is a plan view of the liquid mixer shown in Fig, 1. v

Fig. 3 is an end view of the same liquid mixer. I

Fig. 4 is a partly sectional View of the preferred form of liquid mixer embodying ourinvention. This form may be quickly attached to or removed from the conventional hot and cold water faucets. I

Fig. 5 is a side view of the. form of liquid mixer shown in Fig. 4.

Fig. 6 1s a plan view of a detail. Fig. 7 1s a sectlonal View of the same. The container 10 may be made of anyrigid material suitable for holding Water or other liquids under pressure. It is connected to sources of liquid supply such as faucets 11 and 12, by pipe sections 13 and 14 and has an outlet member 15 and a flexible discharge pipe or hose 16 to provide means for discharging the liquids under pressure and for directing a jet or spray against the surfaces to be cleaned or sprayed in any suitable man ner. The container has a cover 17 adapted to be secured to the container in an air tight manner by screws 18.

The cover has an inlet opening for soap closed by a cap 19. Fig. 4 shows a slightly different arrangement of faucets 11 and 12. WVithin the container 10 is a flexible bag or Provision is made for the.

receptacle 20, for instance, of soft rubber adaptable for holding fluids. This receptacle restson a perforated platform 21 having supporting lugs 22 so that water pressure can be applied. The rim of the receptacle is compressed between the container 10 and the cover 17. This arrangement forms an air-tight seal between the container and its cover and at the same time holds the flexible receptacle in the position shown in Fig. 4.

The receptacle 20 has a discharge member 23 having a control valve member 24. The discharge member 23 is smaller than the discharge outlet 15 and is designed to occupy a position Within it substantially as shown in Fig. 4. The outlet 23 may be secured to the bottom, of the receptacle 20 by a nut 25. V

The member 23 and its valve 24 constitute in effect parts of the outlet member. A pipe section 26' connected to the reservoir 10 is connected to a socket member 27 in an extensible manner. A soft rubber bushing member 28 is adapted to fit over the end of the faucet 11 in a water tight manner. The connection to the faucet 12 is effected in the same manner, so that'the'apparatuscan be readily attached to any ordinary pair of hot and cold Water faucets.

In operation, the flexible receptacle 20 is first filled with a suitable liquid such as soap.

' Then the faucets are opened to provide hot or cold water in the proportion desired. The water (or 'otherliquid) coming into the containerflows'out of the discharge member 15 and at the same time exerts a pressure against the sides of the flexible receptacle 20 and forces out the soap in a quantity which may be regulated, by the valve member 24.

Theliquids readily mix in the tapered section of the discharge member 15 and flow out of the hose 16 to be discharged against the articles to be cleaned or sprayed.

Any suitable form of discharge nozzle with or without a brush such as 30 may be employed. I i

The discharge pipe 16 in Figs. 1, 2 and 3 is shown as swivelled so that it can beturned into the various positions shown. In the form shown in Fig. 4 the flexible hose 16 is dletachable and the brush 30 is also detacha le.

This liquid mixer has proven itself to be very convenient and serviceable in the washing of dishes and other household utensils.
