United States Patent 3,369,724 SILVERWARE CARRIER FOR DISHWASHING APPARATUS Ralph Ettlinger, 1370 Lincoln Ave. S., Highland Park, Ill. 60035 Filed Sept. 12, 1966, Ser. No. 578,638 8 Claims. (Cl. 224-48) ABSTRACT OF THE DISCLOSURE A silverware carrier for a dishwashing apparatus comprising a frame having a plurality of openings its top surface. Silverware receptacles comprising cups for vertically supporting silverware are adapted to be received in said openings. The openings are provided with four corners defining right angles to receive rectangular receptacles while outwardly curved side wall portions are provided intermediate the corners so that the openings may alternatively receive receptacles of substantially circular cross section.

A U-shaped handle is normally separated from the carrier so that a compact arrangement for storage and shipment will be provided. The handle includes bifurcated ends so that it can be connected to the carrier by pressing the ends into additional openings defined by the carrier. The bifurcated ends include enlarged end sections Whereby the handles can be snapped into locking engagement with the carrier.

Specification This invention relates to a silverware carrier for a dishwashing apparatus. The carrier of this invention is particularly useful in connection with operations which involve the handling of large amounts of flatware, such as restaurant operations.

The use of dishwashing machines has become more and more popular, particularly in restaurants andin similar facilities handling large numbers of ware. The dishwashing machines generally operate by providing conveyors which transport china, glass, and silverware through the machine. Spray heads provide the necessary washing water, and detergents are dispensed within the machine so that the ware can all be washed without any handling -by individuals. Racks :are provided for holding the dishes and glasses and, in many cases, the racks can be removed from the machines and employed for stacking and carrying after the completion of a washing operation.

The instant invention is particularly concerned with a new carrier construction which is ideally suited for use in conjunction with operations handling large numbers of ware. The particular arrangement of this invention provides an extremely el'ficient manner for loading of silverware; forachieving the best possible washing action and for holding to a minimum the number of steps required for achieving a proper washing operation.

In accordance with prior art concepts, silverware was often placed on a flat rack and transported in a horizontal position through a dishwashing machine. In such instances, there is a substantial tendency for pieces of the silverware to rest on top of other pieces whereby masking occurs and are thus not exposed to the washing fluids.

Cylinders and other receptacles have been employed for holding silverware wherein the silverware stands upright within the cylinders. This improves the cleaning operation; however, in many instances, the silverware is removed from the cylinders by grabbing the silverware with the hand. Other types of holders permit dumping of the silverware from the receptacles; however, this is objectionable in that wear and tear on the silverware is significant.

It is an object of this invention to provide a silverware 3,359,724 Patented Feb. 20, 1968 carrier for a dishwashing apparatus which overcomes various problems encountered with prior art carriers.

It is a more specific object of this invention to provide a silverware carrier which can be economically manufactured and which can be shipped and stored in a highly eflici'ent manner.

It is a still further object of this invention to provide a silverware carrier which is characterized by versatility in that a variety of individual silverware receptacles can be associated with the carrier, and wherein the silverware is adapted to be held by the receptacles in a manner such that efiicient washing can be accomplished while at the same time permitting removal and handling of the silverware without tendency toward unnecessary scratching of the silverware.

These and other objects of this invention will appear hereinafter and for purposes of illustration 'but not of limitation, specific embodiments of this invention are shown in the accompanying drawings in which:

FIGURE 11 is a schematic illustration indicating the manner in which the carriers are associated with the rack means; and,

FIGURE 12 is an elevational view illustrating the manner in which the frame portion of the carrier is adapted to be stacked for shipping and storage.

The construction of this invention generally comprises a silvenware carrier and dispenser adapted to be used in association with a dishwashing apparatus. The carrier comprises a frame portion and a plurality of openings are defined by the frame portion for removably receiving silverware receptacles. These receptacles are gravitationally supported by the carrier.

The construction may also include a handle portion which is adapted to be snapped into openings defined by the frame portion. The instant invention contemplates an arrangement wherein a plurality of the carriers are stacked together for shipping and storage with the handles being handled separately. When the user receives the parts of the carrier, the handles can be snapped into place in a simple operation whereby the carriers will be all ready for use. With this arrangement, problems involved with bulky constructions, particularly with respect to shipping and storage, are eliminated.

The construction of this invention may also be employed for providing a counter-type dispenser. In this arrangement, carriers of the type described are associated with a rack construction which provides support for the carriers. The rack construction also provides handle means whereby carriers associated with such rack means can 3 be placed directly on a counter-top so that silverware can be removed therefrom. With this arrangement, it is not necessary to transfer the silverware receptacles from the carrier to counter-top receiving openings.

FIGURES l and 2 illustrate a carrier which comprises a frame portion 12 and a handle 14. The frame portion includes an upper surface 16 and downwardly extending and outwardly flared side walls 18. Openings 20 are defined by the frame for receiving silverware holding receptacles 22.

The receptacles 22 are cupshaped, and an outwardly extending lip 24- is formed about the periphery of the top of the receptacles. This lip engages portions of the upper surface 16 which outline the openings 20 whereby the receptacles 22 are gravitationally held by the construction.

It will be noted that the openings 20 comprise four corners 26 which define right angles. Intermediate the corners, the openings define curved portions 28. With this arrangement, the openings 20 will accommodate rectangularly shaped silverware receptacles 22 as Well as cylindrically shaped receptacles. Thus, the receptacles can be manufactured to suit the wishes of a customer while the carriers can be made from a single molding arrangement for accommodating either type of receptacle.

The carrier shown in FIGURE 1 includes a pair of ribs 30 which extend transversely across the carrier. These ribs act to reinforce the carrier against bending movements. An additional rib 32 extends longitudinally of the carrier to resist bending movement in that direction.

The rib 32 is interrupted by a plurality of openings 34. These openings are adapted to receive the ends 36 of the handle portion 14. As shown in FIGURES 5-7, the ends of the handle comprise tapered shank portions which terminate in an enlarged end section 38. The handle ends define a slot 40, and this bifurcated arrangement provides flexibility in the ends.

As best shown in FIGURE 7, the ends are adapted to be pressed through the openings 34, and when the end sections 38 pass through the openings, the end section will snap into place to lock the handles.

An alternative form of the invention provides for the use of a wedge member 42 which is adapted to be pressed into the slot 40 after the handle ends have been snapped into position. This locks the handle ends and insures against accidental removal. As shown in FIGURES 5 and 6, the wedge 42 can be molded integrally with the handle and held in association therewith by means of a cord of plastic 44. The user of the construction can simply cut off the wedge 42 and strip 44 for purposes of assembling the carrier. I

FIGURE 12 illustrates the compact arrangement assumed by a plurality of carrier frames 12 when they are stacked together. As noted, the side walls of the frames are flared outwardly so that the frames will fit together. Obviously, the handles 14 can be packed with the frames without assembly so that a highly desirable arrangement is provided for storage and shipping.

FIGURES 3 and 4 illustrate a modified version 50 of the construction wherein four openings 20 are provided for receptacles 22. It will be noted that openings 34 are provided for the handle 14 whereby the handle can be snapped into place in the same manner as described with reference to the carrier 10.

The carrier 59 is adapted to be manufactured by using the same mold parts as are used in the production of the carrier 10. It will be noted that the construction 50 merely involves the elimination of the central portion of the carrier 10. A mold construction can readily be manufactured wherein a central portion is removable so that the two outer portions can be joined together to form the carrier 59. In this connection, it is of no consequence that each construction includes two extra openings 34.

In the use of the carrier described, the receptacles are adapted to be placed in the carrier whereby a plurality of receptacles can be moved from place to place for load ing purposes. The carrier itself could be located on conveyor means on a dishwashing apparatus, or the carrier can be set on a flat tray in the apparatus. In this connec-- tion, it will be noted that the bottoms of the individual receptacles will rest on the tray surface while the carrier will move downwardly and also rest on the tray surface. The side walls of the carrier are preferably three or four inches in height and this lowering action tends to expose all the silverware for washing while at the same time, providing an easy means for removing the silverware from the dishwashing apparatus since the carrier can simply be lifted off the tray at the end of the washing cycle. Thereafter, the individual receptacles can be carried in the carrier to a place of use.

The described operation obviously involves a great deal of efliciency since the carrier handles the silverware from the time of initial placement in the receptacles, and without any additional handling through the washing cycle to the time of next use.

The construction is also ideal from the standpoint of manufacturing procedures since a relatively small amount of inexpensive materials can be employed. Obviously, a great deal of improvement is achieved when comparing the carrier with wire basket types requiring a great amount of material and costly welding operations during assembly. Polypropylene comprises an ideal material for producing the carriers in a one-step molding operation. As previously noted, the ability to change the carrier from a four to a six receptacle unit by means of a simple alteration of a mold is of prime importance.

In the arrangement shown in FIGURES 8 through 11, a carrier is adapted to be associated with rack means 102. The rack means comprise molded vertically disposed members having an opening 104 whereby an upper bar 106 of the rack means provides a handle arrangement. The horizontzally disposed bottom bar 108 provides leg means for supporting the rack means.

FIGURE 9 illustrates the manner in which carriers 100 can be associated with the rack means. Such carriers define solid side wall portions 110 which flare outwardly. The bottom edges 112 of these Walls are adapted to rest on a flange 114 which extends angularly across the rack means 102. Protruding elements 116 define central openings whereby screws 118 can be employed for securing the carriers to the rack means. As shown in FIGURE 11, a pair of these rack means are employed whereby the carriers can be completely supported. It will be noted that the carriers are disposed at an angle due to the position of the protrusions 116 and the flange 114. This provides better access to silverware when receptacles are placed in the rack means. Obviously, the openings for the receptacles as well as other features of the rack means can be in accordance with the above description.

The arrangement of FIGURES 8 through 11 provides an ideal counter-top dispenser in accordance with accomplishing the other features of this invention. It will be appreciated that the assembled rack means and carrier can be loaded at a dishwashing apparatus and then transported to a counter-top for dispensing of the silverware. There is no need to provide for any transfer of the receptacles to openings in a counter-top which are usually provided for holding such receptacles. It will also be apparent that the arrangement described actually provides a unit which can be employed for picking up silverware before washing and for transporting the silverware through a dishwashing apparatus. In this instance, the assembly becomes the only structure necessary for the handling of silverware.

It will be understood that various changes and modifications may be made in the construction of this invention without departing from the spirit thereof particularly as defined in the following claims.
