Patented Feb. 3, 1931 UNITED STATES PATENT OFFICE NORMAN W. HALSEY, OI YORK, N. Y., ASSIGINOR, BY MESNE ASSIGNMENTS TO PITTSBURGH CLEANSER LABORATORY, INC., A CORPORATION OF NEW YORK CLEANING-MATERIAL FEEDER Application filed June 25,

The present invention relates to cleaning material feeders for washing machines and particularly for the usual types of dish-washing machines. More particularly the invention relates to the type of feeder'illustrated and described in my U. S. Patent No. 1,640,319, dated August 23, 1927, and its object is to improve the operation and simplify and cheapen the construction of the feeder.

The invention will 'be described in detail in connection with the accompanying drawings, in which:

Figure 1 is a cross-section of a typical dish- 15 washlng machine showing my improved feeder in operative position;

Figure 2 is a central vertical section through the feeder;

Figure 3 is a plan view of the same partly 2o biokendaway to exposethe bottom plate there- Figure 4 is a bottom plan of the removable cover showing the inlet valve.

Referring to the drawing, indicates the 25 outer casing of a dish-washing machine, 11 a water tank compartment thereof, 12 the dish rack, 13 revolving spray arms which shower the water upon the dishes in the rack, 14 revolving spray arms which spray the dishes from below, and 15 nozzles for spraying rinse water upon the dishes. The water is kept at a substantially constant level in the tank 11 by means of an overflow pipe 16, and it is constantly circulated through the vertical pipe 17 and the spray arms 13, 14 by means of a suitable pump 1 My improved device for supplying cleaning material to the wash water is indicated at A resting upon a suitable support 19 within the range of the shower of water from the spray nozzles 13, 14. Referrin to Figures 2, 3 and 4, my device consists o a receptacle having a cylindrical side wall'20, a bottom 21, and a top 22 having an upturned neck 23 adapted to receive a flanged cover 24 fitting over the outside of the neck. The cover has a series of perforations 25 to admit water falling from the spray nozzles, which perfo rations may be closed more'or less as desired. 50 by means of a valve plate 26 having similar 1929. Serial No. 373,660.

perforations and ada ted to be rotated upon a central pivot 27. gufiicient water i: permitted to enter the perforations 25 to slowly dissolve the soluble cleaning material contained within the receptacle, and the dissolved material escapes throu h perforations 28 in a raised portion ofthe ottom 21, falling into the wash water in the tank 11.

.When starting the dish-washin machine, with fresh clean water, it is'desira 1e to provide quickly a supply of a cleansing fluid sufficient to charge the water to the requisite strength for cleaning. For this purpose I provided in the device described in the above mentioned patent certain internal compartments to which the water had free access and in which the cleansing material was quickly dissolved. By means of the present invention, these internal compartments are dispensed with, and a cheaper construction substituted which has the additional advantage of being easier to charge and more rapid 1n its operation.

Referring to Fi ure 2, 29 indicates an upwardly extending flange which, as illustrated, is an upper extension of the side wall 20. This flange has perforations 30 for discharge of the dissolved cleaning material, and in conjunction with'the top 22 and neck 23, it constitutes a receptacle 31' to hold a sufiicient amount of cleaning material to primarily charge the wash water to the proper strength for cleansing. It will be apparent that the receptacle 31 is exposed to the shower, and immediately the apparatus is started the material in the receptacle 31 begins to dissolve and to be discharged through the openings 30.

lid 24 is then placed on the neck 23, and thedevice is placed in the washing machine as illustrated at A in Figure 1. The operation will be understood from the foregoing description.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is: a

1. A cleaning material feeder for washing machines adapted to operate within a stream or shower of water, comprisin a closed receptacle for cleanin material aving lapper and lower openings r inlet of water an ischarge of cleaning fluid respectively, and an open top receptacle for cleaning material a apted to receive a charge of cleaning material to provide rapidly a preliminary supply of cleaning fluid, said latter receptacle comprising a perforated wall surrounding and extending upward from the top of the closed receptacle.

2. A cleaning material feeder for washing machines adapted to operate within a stream or shower of water, comprisin a closed receptacle-for cleaning material aving upper and lower openings for inlet of water and discharge of cleaning fluid res ectively, said receptacle having an upwar ly extending neck and a cover fitting said neck, and an open top receptacle for cleaning material comprising a perforated wall extending up- Ward from the side of said closed receptacle and surrounding and spaced from saidneck, substantially as described.

In testimony whereof I hereunto aflix my.
