RINSING APPARATUS FOR DISHES Gilbert M. Motis, Northridge, and Charles H. Fritz, Long Beach, Calif., assignors to Waste King Corporation, Los Angeles, Calif., a corporation of California Filed June 18, 1956, Ser. No. 591,996

Claims. (Cl. 134-172) The present invention relates to an apparatus for rinsing dishes, and the like, to rid them of most food waste thereon and adhering thereto prior to washing them in suitable dishwashing equipment, the invention being intended primarily for use in restaurants, and the like, but not being limited thereto.

A typical restaurant dishwashing installation includes a dish table or trim table over which dishes to be washed are moved on their way to suitable dishwashing equipment, such a trim table conventionally including a dish rinsing apparatus and including a sink leading to a garbage disposal apparatus for comminuting the food waste removed from the dishes by the rinsing device and for discharging the comminuting waste into a sewer, or the like. A primary object of the present invention is to provide an improved rinsing apparatus or device of the foregoing general character. D

More particularly, a primary object of the invention is to provide a rinsing device which is out of the Way when not in use, but which provides maximum flexibility so that it can be used to rinse food waste from dishes with optimum effectiveness.

A more specific object of the invention is to provide a rinsing apparatus which includes a support mounted on the trim table adjacent the sink leading to the garbage disposal apparatus, a rigid tube having an end mounted on the support, and a flexible conduit in this tube and having an end anchored relative to the support, the flexible conduit being longer than the tube so that a portion of such conduit projects from the other end of the tube a substantial distance, and the other end of the conduitbeing provided with discharge means at the end of the projecting portion thereof for spraying water, or other fluid, on the dishes to be rinsed. A related object is to provide a rigid guide tube for the flexible conduit which includes agenerally vertical portion extending upwardly from the trim table, and which includes a generally semicircular portion forming a continuation of the vertical portion of the tube and extending upwardly, outwardly and then downwardly from the upper end of the vertical portion of the tube, the projecting portion of the flexible conduit projecting downwardly from the terminus of the generally semicircular portion of .the

, With this construction, since the flexible conduit is anchored relative to the support adjacent the lower end of the guide tube only, it is free to rotate within the guide tubejto some extent to provide maximum flexibility of movement of the discharge means at the end of the projecting portion of the conduit, this projecting portion itself also contributing to providing the discharge means with virtually unlimited freedom of movement for ease of application of rinsing water, or other fluid, to dishes traversing the trim table, which is an important feature of the invention.

Another object of the invention is to rotatably mount the lower end of the guide tube for the flexible conduit on its support, the guide tube preferably being ro- 2,971,520 Patented Feb. 14, 1961 tatably mounted on a tubular vertical shaft to which the lower end of the flexible conduit is connected in fluid communication with the interior thereof. With this construction, the rinsing apparatus may be swung to one side out of the way when not in use, and may be swung into an operative position when it is to be employed for its intended purpose, this rotary mounting of the guide tube for swinging movement from one position to another about a generally vertical axis also contributing materially to the optimum freedom of movement possessed by the discharge means at the end of the projecting portion of the flexible conduit.

A further object of the invention is to enclose the projecting portion of the flexible conduit in a flexible, protective sheath, this sheath being connected at one end to the discharge means, which is preferably a valveequipped spray head, and extending into the generally semicircular portion of the guide tube. The flexible sheath is not connected to the guide tube and is free to move therein, whereby the sheath protects the projecting portion of the flexible conduit without impairing its flexibility and without interfering with relative movement between the flexible conduit and the guide tube, which is an important feature.

The forgoing objects, advantages, features and results of the present invention, together with various other objects, advantages, features and results thereof which will be apparent to those skilled in the art, may be attained with the exemplary embodiment of the invention illustrated in the accompanying drawing and described in detail hereinafter. Referring to the drawing:

Fig. 1 is a view, partially in section and partially in side elevation, illustrating a rinsing device of the invention installed on a dish or trim table; and

Figs. 2 and 3 are fragmentary, enlarged sectional views respectively taken along the arrowed lines 22 and 33 of Fig. l of the drawing.

The numeral 10 designates a dish table or trim table having a sink 12 to the lower end of which may be connected a garbage disposal apparatus, not shown, for comminuting food waste removed from dishes at the trim table by a rinsing device 14 of the invention mounted on the table. The rinsing device 14 includes a support 16 stitably mounted on the trim table 10 adjacent the sink 12 in communication with a supply line 18 for rinse Water, which may contain a detergent, or other material, the support 16 including a valve 20 for controlling flow therethrough. The support 16 includes an upwardly extending, vertical tubular shaft 22 into which water may flow from the supply line 18 through the valve 20. The shaft 22 may be threaded into the upper end of the body of the support 16 as shown.

Telescoped over and rotatable relative to the shaft 22 about 'a generally vertical axis is the lower end of a rigid guide tube 2.4, the lower end of this tube resting on an annular shoulder 26 on the support 16. The guide tube 24 includes a generally vertical portion 28 and includes a generally semicircular portion 3t) which forms a continuation of the vertical portion 2.8 and which extends upwardly, outwardly and then downwardly. While the portion 30 is shown and described as semicircular, it will be understood that any configuration which, in effect, produces a bend in the guide tube 24 may be utilized, the term generally semicircular being intended to cover any such configuration.

Within the guide tube 24 is a flexible conduit 32., such as a hose, the lower end of this flexible conduit being anchored relative to the support 16. As shown, the lower end of the flexible conduit 32 is provided with a coupling 34 which is threaded into the upper end of the tubular shaft 22 for the guide tube 24.

The flexible conduit 32 extends through the guide tube 24 and projects from the free end thereof a substantial distance, the projecting portion of the flexible conduit being identified by the numeral 36. The end of the projecting portion 36 of the flexibleconduit 32 is provided with a coupling 38 which is threaded into a discharge means 40 comprising a spray head 42 equipped with a valve 44. The discharge means 40 is provided with a tubular handle 46 which encloses the coupling 38 and the lower end of the projecting portion 36 of the conduit 32, the valve 44 having a handle 48 which lies closely adjacent and parallel to the handle 46 so that the valve 44 may be opened to release water from the spray head 42 merely by squeezing the handle 48 toward the handle 46.

The projecting portion 36 of the conduit 32 is enclosed by a flexible, preferably metallic, sheath 50 one end of which is connected to the discharge means 40 through the coupling 38, the other end of the flexible sheath projecting into, but being unconnected to, the free end of the guide tube 24.

With the foregoing construction, maximum freedom of movement of the spray head 42 relative to the support 16 is provided. In other words, it is possible to swing the guide tube 24 about a vertical axis into any desired position and it is possible to move the spray head 42 into any desired position relative to the guide tube, the entire flexible conduit 32 between the spray head and the coupling 34, including the portion of the conduit 32 within the guide tube, being rotatable to permit this, and the projecting portion 36 of the flexible conduit within the flexible sheath 50 being bendable to accomplish this result. Thus, the spray head 42 may be maneuvered into any desired position in carrying out its rinsing function so that any object of any shape or size in any location on the table may be rinsed easily and quickly, which is an important feature of the invention.
