- I DISHWASHING APPARATUS *Filed March 21, 1958 s Sheets-Sheet 2 Patented Aug. 13, 1940 UNITED STATES PATENT OFFICE I 9 Claims.

My invention relates to improvements, in dishwashing apparatus, an object thereof being to supply a simple, durable and effective apparatus of such nature adapted to be readily applied to the hot and cold water pipes leading to a sink and toprovide a spray either of clear water or suds varying in temperature, as may be desired, from that of the waterin the cold-water pipe to that of the water in the hot water pipe and varying in pressure up to the maximum of that afforded by the water in said pipes.

Another object of the invention is to provide an apparatus of the present nature, including a receptacle having a closed soap chamber adapted v to receive clear water and discharge soapy water.

through a single valve in one position thereof, such valve, in another position, serving to shunt theclear water past said chamber and, in another position, to arrest the flow of water and 30 drain said chamber under atmospheric pressure.

A further feature of the invention resides in 30 ber in such manner that a relatively large quantity of water may be introduced into the chamber through the inlet before the admission of additional water is substantially resisted by the pressure of air trapped in the upper portion of 35 said chamber. 4

Other objects of the invention reside in the novel combination and arrangement of parts and in the details of construction hereinafter illustrated and/or described. v

In the drawings, Fig. 1 is a front elevational view of a dishwashing apparatus embodying my invention, the same being shown as applied to hot and cold water pipes leading through the back board of a sink; Fig. 2 is a side elevational view of the structure shown in Fig. 1; Fig. 3 is a sectional view, in detail, illustrating particularly the soap receptacle of the illustrated apparatus, said view being taken as on the line 33 of Fig. 2; Fig. 4 is a detail sectional view taken as on 50 the line 44 of Fig.2, said view showingpartic- 5 to the view of said construction shown in Fig. 3,

but with the valve body turned to a difierent position; Fig. 7 is an elevational view, in detail, of the valve plug illustrated in section in Figs. 3 to 6, incl., and Fig. 8 is a detail sectional view of the spray nozzle illustrated in elevation in Fig. 1 and 5 in perspective in Fig. 2. Referring to the accompanying drawings in which similar reference characters are employed to designate similar parts throughout .the several views, it will be seen that the illustrated embodi- 10 ment of my invention includes a receptacle l0 mounted upon and connected with branch feed pipes ll, l2, respectively coupled with hot water and cold water feed pipes l3, [4, leading through the back board ii of a sink and supplying water 15 to a combined hot and cold water faucet l6 having a pivoting spout ll. The branch feed pipe l2 includes a control valve I8 which is screwed into a T-coupling or adapter l9 interposed between the end of the cold water pipe l4 and the faucet 2 I6. Likewise, the branch feed pipe ll includes a control valve screwed into a T-coupling or adapter similar tothe T-coupling l9, such valve being interposed between the end of the hot water pipe l3 and the faucet [6. Each of said valves I8, 20, has a lever 2i for opening and closing the same and for regulating the flow of water 'therethrough from its respective water pipe.

A coupling 22 connects the branch 'feed pipes ll, l2, with a valve housing 23 formed integrally v anchored in the body of the receptacle [0 provide bearings for the ends of a. pivoting yoke 29 through which is fitted a threaded clamping screw 30 having a finger piece 3|. The inner end of this clamping screw 30 is received in a depression 32 formed in the closure 24 axially thereof, said closure being removably clamped against the sealing gasket 21 by means of said clamping screw 33. With the closure 24 removed from the body of the receptacle l0, cakes or slabs of soap may be introduced from the .top into the soap chamber 33 within said receptacle, but with said closure 24 clamped in place, the chamber 33 is tightly sealed at the upper portion. of the receptacle.

The valve casing 23 is formed with a horizontally disposed tapered bore 34 and fitting this v bore is a correspondingly tapered valve plug 35,

branch feed pipes ll, 12,

thrust plug 31 is a compression spring 39 into the inner end of which is fitted a thrust head 40. This thrust head 40 and said valve plug 35 are formed with opposed depressions 41, 42, which receive opposite portions of a thrust ball 43, the action of said compression spring 39, thrust head 40 and thrust ball 43 being to maintain a tight fit between the valve tuning of said valve plug. Secured to the small end of the tapered valve plug 35 is a handle 44 for turning said plug. This handle 44 is secured to the plug 35 by means of a fastening screw 45 passing through 'said handle and threaded into said plug, relative rotation between handle and plug being precluded by means of a key-pin 46 accommodated at its inner end in a bore 41 in said plug 35 and at its outer end in a bore 48 in said handle. The valve plug 35 has a diametrical bore 49 therein and at one side thereof a circumierentially extending channel 50. At the other side of said diametrical bore 49, said valve plug 35 is formed with a longitudinally extending channel 5|.

The valve casing 23 is formed with a feed port 52 into which the coupling 22 is threaded. In line with said feed port and formed in the bottom of the receptacle 10 is an inlet port 53. Said feed port 52 and said inlet port 53 are brought into communication for conducting water from the into the soap chamber 33 within the receptacle Ill. To thus bring said feed port 52 and inlet port 53 into communication, the valve plug 35 is turned into a suds position, wherein the diametrical bore 49 in said plug registers with said feed port 52 and inlet port 53 (Fig. 3). The said casing 23 is additionally formed with a delivery port 54 into which the coupling member 55 of a spray tube 56 is threaded and said casing is further formed with an outlet port 51 in the bottom of the receptacle I9, said outlet port 51 and said delivery port 54 being brought into communication in the suds" position of the valve plug 35 through the circumferentially extending channel 50 in said valve plug 35. Issuing upwardly into the receptacle 10 from the outlet port 51 is a tubular extension 58, which is closed at the top thereof, but formed plurality of perforaat its upper portion with a tions 59 bringing the chamber 33 within the receptacle I into communication with the bore of said tubular extension 58. The inlet port 53 is disposed co-axially of the soap receptacle I0 and the inner wall surfaces of said receptacle, at the lower portion thereof, slope inwardly toward said inlet port 53 in order that the cakes or slabs of soap contained within the receptacle chamber 33 will be directed, in gravitation, to the bottom of said chamber into position immediately above or near said inlet port 53. The tubular outlet extension 58 issues from the outlet port 51 at an angle to the axis of the soap receptacle l0 and occupies a position closely adjacent to the sloping wall surface of said receptacle chamber, whereby the pieces of soap within the receptacle are not interfered with by said extension 58 in their descent in the receptacle chamber to position above the inlet port 53. With the valve plug 35 in the suds position, as shown plug 35 and' the tapered bore 34 ofthe valve casing 23, yet permit the in Fig. 3, the water from one or both of the branch feed pipes .l I, 12, under desired regulation, enters the soap chamber 33 where it is saponified and thence directed into the spray tube 55.

The circumferential channel 53 in the valve plug 35 brings the feed port 52 into direct communication with the delivery port 54 in a clear position of the valve plug 35, as best shown in Fig. 6. Functioning to thus bring said feed and delivery ports 52, 54, into communication, the channel 59 in the valve plug 35 shunts the water fed from the branch feed pipes ll, .12, into the spray tube 56 in order that such water will not be subjected to the soap within the receptacle In addition to the suds" and clear positions of the valve plug 35 previously noted, said plug may be turned into a third or drain" position, best shown in Fig. 4. In said "drain" position of the valve plug 35, the diametrical bore 49 therein registers with the delivery port 54 and also with a drain port 6ll.formed in the bottom of the soap receptacle 10. Any water contained in said receptacl'e drains therefrom through said drain port 50, diametrical bore 49 in valve plug 35, and delivery port 54 into the spray tube 56. This drainage of the water from the soap receptacle I0 is initially enhanced by such air as may be trapped under pressure in the upper portion of the soap chamber 33 in receptacle l0. Subsequently, and when this air becomes of the same pressure as that of the atmosphere, air from the outside is admitted into the receptacle chamber 33 through the outlet extension 58 so that the drainage from the receptacle may continue unimpeded. To provide for the admission of air into the interior of the receptacle chamber 33, an air ingress port Si is formed in the valve casing 23. This port Bl communicates with the outlet port 51 through the longitudinally extending channel in the valve plug 35, said air port 6| being supplied with a valve cage 62 in which ,a ball check 63 is contained, said ball check operating to prevent the escape of air and/or water through said air port 61, but permitting the ingress of air therethrough.

Fixed to the front of valve housing 23 is a plate 64 bearing the designations suds, "clear and drain with reference to which the handle 44 of the valve plug 35 is turned to supply soapy water or clear water through the spray tube 58. or to drain the soap receptacle through said tube. Any suitable nozzle may be provided at the end of the spray tube, such as that shown in detail in Fig. 8 and designated by the numeral 65. This nozzle includes a tubular handle 56, in'which the terminal portion of the spray tube 56 is contained, said tube being connected with a nipple G1 issuing from a body 68 threaded within said handle 66. A head 59 formed with fine spray forming perforations 19 and threaded on the body 68 clamps a cup-shaped scraper member 11 between it and the end of said handle 66.

When the valve plug 35 is turned into its .suds" position, after the receptacle has been drained, water from one or the other or both of the branch feed pipes ll, 12, according to the adjustment of the valves 2| insaid pipes, enters the receptacle through the-feed and inlet ports 52, 53, and the diametrical bore 49 in said plug, the air within said receptacle chamber 33 being driven out of the same through the spray tube 56 until the level of the water in said receptacle seals the perforations 59 in the tubular outlet extension 58. The

lating in the receptacle chamber 33, being added under the pressure of the air trapped in the upper portion of said chamber. Thus, it will be seen that by locating the perforations 59 in the tubular outlet extension 58 at an elevation substantially above the bottom of the receptacle chamber 33, a substantially greater amount of water is provided within the receptacle for contact with the soap therein than wouldbe prb-' vided were the outlet from the receptacle chamber to be sealed immediately upon the initial influx of water into said chamber. This provision, wherein a substantial quantity of water is at all times subjected to the soap, contained in the thefspirit of my invention.
