Application April 5, 1947, Serial N 0. 739,705

2 Claims;

This invention relates to" a device in dish washing machines for recovering silverware and the like and, more particularly, it refers to a washing and pre-wash-ingdevice for dishes, glasses and cutlery for use in restaurants and other establishments, and for selectively trapping any escaped silver or small dishware and large particles of waste food material which ordinarily would go into-the drain in normal washing operations thereby plugging the drain.

It is an object of this invention to provide a dish and cutlery washing unit adapted to permit removal of waste food matter without the loss of any of the dishes and cutlery from the unit.

One other object of this invention is to provide a novel washing unit provided with easily removable trapping means for preventing the loss of any small objects that are to be washed.

Still another object of the present invention is to provide a dish and cutlery washing machine unit for continuously recirculating the wash water at a predetermined temperature while constantly draining and replenishing the supply of said wash water, said machine having easily removable trap means for reclaiming any cutlery or other ware which may have been washed down towards the drain of the machine, and waste food matter collecting means for preventing clogging of the drainage line connected to the unit.

A more specific object of the present invention the invention will become apparent from the following description taken in connection with the accompanying drawings in which:

Fig. 1 is a perspective view of a preferred. embodiment of the invention;

Fig. 2 is a vertical sectional view taken on line 2-2 of Fig. 1;

Fig. 2 is avertical sectional View taken on line 2--2 of Fig. 1;

Fig.3 is aplan view taken online 3-3of Fig. 2; Fig. 4 is a perspective view of aplurality of removable elements contained in the embodiment shown in Figs. 2 and 3;

Fig. 5 is a plan View taken on line 5-5 of Fig. 6; and '1 Fig. 6 is a vertical sectional view taken on line 6-6 of Fig. 1.

Referring now to the drawings in which like reference characters denote like parts throughout, there is provided a washing machine Ill consisting of an upper compartment or housing II and a lower section or housing [2 mounted preferably on foot rests or pedestals Is, as shown. It will be noted that, for purposes of illustration, the upper and lower housings ll and I2 respectively are integral with respect to each other whereas, in practice, the housings may be separated from each other-in any suitable manner.

Upper housing II, as shown, consists of the top, side and rear walls, Hi, [5, i6 and i1, respectively, while the front I8 of housing H is open and is provided with an extension platform 19, as

in Figs. 2 and 6, which normally, during thewashing operation, would contain dishes, saucers, glasses, cutlery, etc. It will be noted that the tray 23 is so constructed that, during the washing and cleaning operation of the contents, the water will easily flow downward into housing 12.

Below said bracket 26 there is provided a bridge plate 24 whose edges are fixed to the bracket 29 and to the walls of the housing by any suitable means, such as spot welding, as shown in Fig. 2'. Said bridge plate 24, it will be noted, extends outward-1y to platform l9 forming the flooring for same and slopes towards its center constituting a slot type of drain pipe 25 extending into thelower housing l2. Disposed at the top and bottom of the upper housing I l are sets of spaced perforatedpipes 26 and 21 which extend from the interior of rear or end wallll to the open or front end l8 of the housing ll. Set 26 is fixed at the ceiling of housing I 1 while the other set connected to a recirculating unit or sump pump 30, as shown in Fig. 1. Said feed line 29 is connected' to a source of hot and cold water, not

shown, and is controlled by a plurality of valves,

not shown. With respect to the extending platform l9, it will be noted that the front edge 3| is provided with a clearance space or recess 32, as shown in Figs. 5 and 6, to permit the attachment thereto of an auxiliary platform 33 for resting thereon additional trays containing washable kitchenware.

Disposed below the housing II, as heretofore indicated, is lower housing |2 which is provided at the bottom thereof with an overflow pipe 34 in connection with a drain pipe 35. It will be noted that the bottom of housing |2 forms an overflow basin 3B and contains an outlet feed pipe or conduit 31 which is in connection with the recirculating unit or pump which, in turn, forces the water upwardly along the pipe 29 to the top and bottom tiers 26 and 21 of spaced piping in the upper housing Said lower housing l2, as constructed, is provided with spaced supporting plate members or angle runners, 38 and 39, respectively, extending a from the front wall 40 to the rear wall 4|. The runners 38 and 39 are connected with vertical plate members 43 and 44 which connect at their upper ends with bottom wall 45 of housing I A perforated basket 42, as shown inFig. 3, slides easily on runners 38 and 39. Said basket 42 may be easily withdrawn from the lower section by merely grasping the handle 46 on the face piece 41 of said basket.

Said basket 42 is provided with opposed rests 48, mounted in any suitable manner on the inside face of front and rear walls 49 and 50 of said basket, for retaining thereon a removable catch tray 5| which extends the full length of the basket 42 and which is disposed directly below the slotted opening of drain pipe 25 of the bridge plate 24, as shown in Fig. 2. Said catch tray 5| is provided with a plurality of holes or openings 52 in its floor 53 to permit drainage of water from the tray. It will be noted that said basket 42 can be easily removed from lower compartment 12. Also said catch tray 5| can easily catch escaping dishes, silver ware and other small items while any waste food matter, escaping from the tray 23 onto tray 5|, will be washed over into perforated basket 42 by the continuous stream of wash water flowing down the drain of the bridge plate into the lower compartment l2.

In order to prevent any 'water from leaking from the lower section |2 during the washing operation, there is provided a drop door 54 forming a platform when in the open position, as shown in Fig. 1, which contains baffle plates or wall 55 and 56, respectively. At its lower edge, said drop door 54 is pivotally hinged to the lower portion of the front wall 49 of the lower section I2. The upper portion of said drop door 54 is provided with a locking member 51 adapted to keep said drop door in closed position with respect to the front wall 40, as shown in Fig. 2. It will be noted that the lower portion of the front Wall 40, adjacent the hinged area of the drop door, is provided with a drip gutter 58 extending slightly beyond the width of said drop door 54 so as to collect any water that may seep through the baffle walls of said door. The lower section of front wall 40, disposed opposite gutter 58, is provided with a plurality of openings 59 to permit the drip collecting in the gutter to flow into the bottom 36-.

It will be noted that, in order to remove any food refuse that collects on top of catch tray 5| in spite of the wash water flowing over the tray,

. there is provided a brush member 6|, pivotally connected short of one of its ends in wall 62 of 4 compartment I2. Said member extends through a slotted portion 63 of wall 43 and over the top of tray 5| whereby it can be moved to scrape the top of said tray.

In accordance with Fig. 1, it will be noted that I have provided a by-pass pipe 64, shown by the dotted lines, extending from the pipe 65 to the bottom of the bridge plate under the extension platform l9 to which a flexible hose may be attached in order to initially wash off any food waste present among the dishes to be washed in compartment l0.

During the washing operation the open front end portion l8 may be covered by any suitable material, such as canvas or waterproof cloth, to prevent the escape of the water from the compartment.

From the foregoing description, it will be noted that I have provided a compact, easily operable and economic washing machine in which the water is recirculated and gradually replenished,

the temperature of said water being controlled by suitable thermostatic means. Furthermore, a flooring is provided in the upper compartment for sliding cutlery and dishware to a removable unit in the lower section which is adapted to recover any silver ware that may have dropped from the washing tray in the upper compartment. Said tray 5| can be easily handled and removed from the lower section by means of handle members 60. A perforated basket is provided for holding the catch tray and collecting any food waste which is washed over the catch tray into the basket. There is also provided in the lower section, a drop door which, when closed against the front face of the lower section, forms a closure with said front wall preventing water from escaping from the lower section.

While a preferred embodiment of the invention has been described and shown herein, it is to be understood that various modifications as to form, use of materials and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed herein.
