Referring to these drawings, the machine includes a cylindrical or drum-like tank 10 (Fig. 1), the interior of which constitutes the washing chamber. Tank 10 is prefen ably portable in order that it may be moved to and from the dining room for convenience in loading and unloading it, and to this end the tank is shown as supported by a suitable framework 11 which is mounted in turn on casters 12. The'framework 11 preferably consists of three uprights arranged in triangular arrangement (Fig. 2).
Within the washing chamber, there is a suitable support, or container, for the dishes to be washed, which preferably takes the form of an open mesh basket, represented generally by reference letter B in Fig. 1.
The main frame of this basket consists of two circular rings 13 and 14, which may advantageously be formed of heavy wire. The rings 13 and 14 are of different diameter,-'the larger ring 14 being disposed above the smaller ring 13 in concent-rical relation therewith and in a plane parallel to that in which ring 13 is located. The rings 13 and 14 are held in this relation and are supported from the baseof the tank 10 by a series of members (three as shown) which are disposed in angularly spaced rela- I tion about the rings. Each of such members consists of a wire 15 looped, or otherwise joined at one end, to ring 14 and extending to ring 13, to which it is joined, as by looping the wire therearound or otherwise. The wire 15 then extends a short distance inwardly from ring 13 to form a ledge 15 and then outwardly therefrom. This outwardly extending portion is bent downwardly and then back upon itself in substantially U-shape form to form a supporting leg 16, the free end of the wire 15 being finally looped around, or otherwise joined to, the ring 14.
The base of basket B preferably takes the form of a removable grid G, upon which hollow ware, such as cups, glasses, bowls and so forth, may be supported in inverted relation as indicated in Fig. 1. Grid G, as best shown in Fig. 12 includes a series of rings 17, preferably of wire, and all of different diameter, which are located in substantially concentrical relation and disposed in a common plane. Below these rings is a series of cross wires 18, which are disposed radially of the rings and are suitably joined thereto as by brazing, soldering, welding or the like. The outer portion of the grid rests upon ledges 15' whereby the grid is supported, and the marginal portion of the grid is presented against, or limited in lateral dis lacement by engagement with ring 13. e inner ends of wires 18 are bent upwardly, as best shown at 20 in Fig. 13, and are suitably joined to a ring 21. The portions 20 form an upwardly fiarin socket for the reception of-a frusto-conical older 5 (Fig. 1) herein shown as fashioned from forammous metal and having a central tubular portion 23 extending upwardly from its base. The portion 23 is provided to receive a rotatable spray pipe and prevent the articles in holder from engaging such pipe. The holder S is obviously removable from the grid, when desired, and is adapted to receive silver ware and the like. For supporting a milk bottle or the like, so that it will drain, the mouth of the bottle is rested on grid G and a holder H, removably secured to the holder S, is provided to prevent it from tipping. This holder H may advantageously beeformed from wire bent up in the manner shown in Figs. 16 and 17 to provide two coils 24 and two curved spring arms 25 which extend outwardly approximately at right angles thereto and are curved to encompass the bottle. The coils 24 form a spring clip for attachment to holder S 'in an obvious manner.
Plates, platters, saucers and other dishes of a substantially flat nature are stacked on edge around the periphery of grid G in suitable holders. Preferably, each of these holders is formed of a wire 27 bent to form a series of open coils 28 Figs. 1, 14 and 15.
Each holder extends from wire 13 diagonally upwardly to the wire 14 and the ends of wire 27 are suitably attached, as by looping them around, the wires 13 and 14. A large number of these holders are provided at closely spaced intervals about the pe ripheigy of the basket and they form the side walls for the latter. The dishes are inserted between the coils 28, as shown in Fig. 1, and these holders permit a large. number of dishes to be stacked on edge about the outer portion of the basket, preferably in several closely adjacent circular series, as shown.
The tank 10 is closed at its upper end by a cover which preferably com IISCS two unequal sections 29 and 30 suita ly hinged together (Fig. 1). As shown, this hinge connection consists of interengaging flanges 31 and 32 turned inwardly from the sections 29 and 30, respectively,one of these flanges, as 31, having a portion 33 curved with member 32 as a radius to permit relative swinging movement between the cover sec tions. These interengaging flanges also insure against leakage of water through the hinge connection of the cover sections during the Washing operation. The outer marginal portions of the cover sections are turned downwardly, forming flanges 34 which rest upon a head 35 formed in tank 10. This ongagement of flanges 34 with bead is such as to insure against the escape of water from the washing chamber during the operation of the machine. The larger cover section 30 is ordinarily used to gain access to the washing chamber and basket B for the purpose of loading and unloading the latter. However, when the machine is not in use, the smaller cover 29 may be raised for the purpose of permitting a circulation of air within the washing chamber. When the machine is not in use, the section 30 may be used as a table and the section 29, being raised as just described, serves as a back for the table thus afforded. The cover, as a whole, may be turned relatively to the tank and also readily iemoved as an entirety therefrom. Suitable handles, such as 36, may be provided on the cover sections 29 and 30 to facilitate the lifting of them. Two hooks 37 (Figs. 1 and 10) are provided on the smaller section 29, one on each side thereof and near the hinge connection. These hooks extend downwardly from the cover and exteriorly of the tank, being disposed closely adjacent the peripheral wall thereof in order to prevent by their engag ment with such wall any substantial longitudinal movement of the section 29, when section 30 is in open position, which might otherwise occur.
When hot water is discharged into tank 10 with the covers in closed position, there results anexpansion of the air in the tank and such expansion tends tvand frequently does lift one of the cover sections, allowing water to be thrown out of the machine. To prevent this undesired result, I provide a plurality of perforations 38 in the cover, as for eX- ample in section 29 (Fig. through which air may freely pass. Beneath the perforations, and spaced therefrom is a shield 39 suitably fastened to the cover at one end by an angular extending portion which closes such end against ingress of water. The other end is left open for the passage of air to or from the perforations. As a matter of practice no water enters this end because all streams striking the cover section 29, between such end and the adjacent Wall of tank 10, do so in substantially vertical directions. i
Fixed to the base of tank 10 is a casting 40, which communicates with the washing chamber through an opening 41 (Fig. 1). This opening is provided with a screen 42 carried by a ring frame 43, which fits in a socket formed in casting and is removable therefrom by means of a handle 44, spanning ring 43 diametrically and secured at its ends thereto. Access to the screen 42 is bad by removing the grid G. The casting 40 extends beyond the outer periphery of tank 10 and extends upwardly in closely adjacent relation with tank 10 for a short distance to provide a reservoir 45 and the opening 41 is in constant communication with reservoir 45 by means of a passage 46 which slopes toward, and drains into. the reservoir. Also formed in casting 40 is an inlet pipe 47, one end of which projects into the passage 46 for connection to the discharge pipe of the pump, to be later described, and the other end of which opens into the base of the washing chamber,such' end being turned vertically upward for this purpose.
Water is distributed in the washing chamber for washing and rinsing purposes by means of a spray rotor, which comprises two diametrically opposed horizontal tubes 50 and a central vertically extending tube 51. The former underlie the basket B and the latter passes upwardly through and above the described tube 23. vThese tubes 50 and 51 are suitably fixed, as by soldering, in a hollow, cross-like fitting 52 and in three of the four openings thereof. \Vithin the fitting 52 is hub 54 (Figs. 5 and 6) to which is fixed a rod which extends downwardly through andbeyond the other opening 53 of thefitting. The hub 54 is connected to the Walls of fitting 52 by webs 54 which function as curved bafile plates to deflect part of the water into oneftube 50 and another part into the other tube 50. These webs, however, do not entirely close off the upper interior portion of fitting 52 and openings 53, on opposite"sides of hub 54, are left to permit water to pass to tube 51. The hub 54 and its ,webs 54 are utilized to distribute the stream, which passes upwardly in openings 53, and divide and apportion it properly. As shown, substantially one quarter of thestream is deflected into each tube 50 and one half into tube 51.
The lower endof fitting 52 is rotatably mounted in the vertically disposed open upper end of inlet pipe 47 (Fig. 1) and rod 55 extends into such end of the inlet pipe and is received in a suitable bearing formed in the lower portion of the wall thereof. Fitting 52 carries a flange 56 which rides upon the upper end face of inlet pipe 47 and overlying this flange is a latch 57 car ried on one end of a spring 58 which is fixed at its other end to the hub of inlet pipe 47. The latch 57 prevents the spray rotoixfrom being displaced upwardly by the pressure of the water while the machine is in operation. This construction also per-,
niits the spray rotor to be conveniently removed as an entirety for cleaning and inspection, when desired.
The tubes'50 of the spray tube are alike in construction. Each has a plurality of outlets to direct water in a general upward direction and these outlets are preferably something more than mere holes drilled through the wall of the tube. Rather they are scientifically formed nozzles to direct the water in a definitely planned way. The tubes for the sake of lightness have thin walls, and to permit proper nozzles to be formed in such walls, the tubes are made up from flat sheet metal.the nozzles v being first formed and then the sheet being rolled up into cylindrical form and the longitudinal seam welded or soldered. Typical nozzles are shown in full detail in Fig. 3 at 60 and60'. They are formed by punching the metal outwardly, and in this manner walls of substantial length are provided for the nozzles, whereby to effectively direct the streams issuing therefrom. Preferably, as shown in Fig. 3, the nozzles 60 are given a slight slant, backwardly from the direction in which the water passes through the tube, to counteract the tendency of the jets, 1ssuing from the nozzles, to deflect in the opposite direction. described, the jets issue therefrom in 'vertical' directions. The nozzles 60', however, are slanted in a reverse direction because. it is desired to have the streams emitted in a slanting direction to strike the walls of tank 10. v
The tubes 50, being formed from sheet metal, as described, have open ends and the outer open end of each is closed byaplug 61. A spring loop 62, having the endsthcreof seated in oppositely disposed small recesses-in the wall of tube 50, engages the outer face of plug 61 and holds it in place against the pressure of the water inrthe tube. The central portion of loop 62, preferably seats in a slot 63 in plug 61. To re- By slanting the nozzles, as 5 move the plug the side portions of loop 62 are squeezed together which frees the central portion from slot 63, whereupon the loop may be swung downwardly out of the way to permit the plug to be pulled out.
The nozzles are preferably arranged in three series,of which two, comprising nozzles 60 and 60, are arranged on the top portion of the tube. The inner series, comprising the nozzles 60, from which sprays issue vertically upwards, serves to direct water into the interior of the hollow ware supported on grid G. The outer series, comprising the nozzles 60', from which sprays issue in outwardly slanting directions, directs water against the wall of tank 10 and such water travels upwardly along the wall until it strikes the cover, where it is deflected downwardly striking against the backs of the dishes in the spring coil holders 28. Some of the water from the last named series of nozzles probably strikes the side wall of tank 10 and is deflected laterally against the backs of the dishes. The third series of nozzles are shown at (34 and are so located that the reaction from the jets rotates the spray rotor. The last named nozzles throw long curving streams, some of which strike u wardly against the faces of the dishes in t e spring holders 28, and others of which strike the wall of tank 10, travel upwardly along such wall to the cover and are then deflected downwardly upon the backs of the dishes in holders 28.
The downward distribution of water upon the articles to be washed is effected by nozzles in a spray ball fixed to the upper end of tube 51.- This spray ball, as shown in Fi s. 18 and 19 is made in two sections 65 and 66,the former having a hub 67 for attachment to tube 51, in any suitable way, and a spider 68 in the interior of the hub, and the latter having a central opening to receive a screw 69 which threads into the spider 68 and clamps the two sections together. The spray ball has in its peripheral wall two like series of nozzles 70. Each series extends half way around the circumference of the spray ball and the nozzles in each series are laid out in a curve, such as a portion of a helix. Each nozzle of a series is therefore located in a different plane. In addition, each nozzle 70 of each series is directed at a different angle to the vertical axis of the ball. Starting with the highest nozzle of a series, the jet therefrom issues substantially horizontally, or at right angles to the axes of the ball. Such jet wilLstrike the side wall of tank 10 and be deflected back against the articles in .the basket and a piortion of this jet may even strike the un ersides'of the cover sections 29 and 30 and be deflected downwardly. The next nozzle 70 of a series may direct its jet at a slight angle to the'horizontal, the next at 21 greater angle and so on until the last nozzle of the series is reached which directs its jet into the silver holder S. By means of the spray ball, water is directed from almost every conceivable angle against the dishes, mostly downwardly although, as set forth above, some of the jets strike the side wall of the tank and are deflected in various ways, some striking more nearly horizontally against the articles and causing the backs of the dishes in the spring holders 28 to be washed from above. The spray ball directs water over the faces of the dishes in these holders, over the exterior surfaces of the hollow ware and into the silver holder S.
Due to the varied angularity of the nozzles in the spray ball, it is an exceedingly diilicult part to manufacture by ordinary methods. That is, if the nozzles were drilled, each would have to be drilled separately. It is diilicult to devise jigs or forms to facilitate the work and the latter would have to be performed largely by hand. The accuracy of the directions of the nozzles and uniformity of the work would be seriously impaired. To avoid all this and reduce the cost of manufacture of this part to a minimum, I have found that I can construct the device in the two sections described, each of which can be die cast. The spray ball is split along two curvedlines 71, the ends of which are joined by vertical lines 72. The lines 71 are those along which the nozzlcs 70 are laid out and the two sections separate along the center lines of the nozzles so that the latter may be formed by casting and accuracy and uniformity of work insured. This construction is also advantageous in that it permits the spray, ball to be conveniently opened up for cleaning.
The pump, by means of which water from reservoir 45 is forced through inlet pipe l7 and the spray rotor, is separable from the washing machine and constitutes, with its propelling means, a distinct unit, which can be separately manufactured as such and thereafter applied'to the machine in a comparatively simple manner. This unit is shown, apart from the washing machine, in Fig. 7. The motive power for the pumping apparatus preferably consists of an electric motor, indicated conventionally at 75. This motor may be of small size, but should run at very high speeds and a motor, similar to those used on the ordinary household t pe of vacuum cleaner, has substantially the esired characteristics. The frame of motor 7 5 has two lugs 76 provided thereon through which freely pass the upper ends of two vertically disposed distance rods 77, having nuts 78 threaded upon their upper ends. Below each lug 76 and coiled around its red 77 is a spring 79 and below the spring a resilient, and shouldered bushing 80, such as rubber or the like. These shouldered bushings slip lugs 82 on the interior and near the upper end of the casting forming reservoir 45, with sirably consist of a rubber hose 85.
the shoulders of the bushing resting upon the lugs and thus supporting the springs 79. The lower ends of rods 77 are offset inwardly sufficiently to freely slip between lugs 82 and as the unit is lowered into reservoir 45, the upper portions of the rods enter slot-s 81. The motor is supported yieldingly by these springs, and in such a manner as to prevent the transmission of vibrations to tank 10, which, on account of its drum-like character, would intensify these vibrations and make the machine very noisy in operation.
The lower ends of rods 77 are fixed to, and support, a casing 83 which has a central axial opening therethrough and two orts 83 and 83 leading laterally therefrom Fig. 11) The port 833 communicates with a pipe 84;- fixed to casing 83, which pipe, as shown in Fig. 1, is adapted to be connected to the inlet pipe 47. Preferably, this connection is effected in such a manner as to prevent the transmission of vibrations from the powerpumping device to'tank 10 and may ldehe port 83 communicateshwjth a. vertically disposed discharge pi e 86v which extends up wardly outside tan 10 for a purpose to be later described. Rotatably mounted in the central axial opening in casing 83 is, a plug valve 87 having a closed upper end, a chamber 88, an opening at its lower end to chamber 88, and alateral port 89. which may be moved into registry with either port 83 or 83 by turning'the plug valve. The latter I has a flange 90 at its upper end which rests upon the upper face of casing 83 and sup ports the plug valve. The chamber 88 receives a screw 91, having a spindle 92 which extends upwardly through, and is rotatably mounted in, the plug Valve 87. As shown in Fig. 1, the casing 83 is adapted to be positioned in-reservoir 45 and, on rotation of the screw 91, water entering chamber 88 through its open lower end is forced through port 89 into one or the other of the ports 83 and 83 and thus either into inlet pipe 47 or into discharge pipe 86, the purpose of the latter being to drain the reservoir 45. Drain openings w are provided in the lower walls of ports 83 and 83 to prevent the trapping of water therein and in the pipes connected' thereto when either of the ports is closed off. Complete drainage of the reservoir may be effected, whenever desired, by removing :1 lug 93 in the base of reservoir 45.
he pump screw 91 is rotated at very high.
speed by motor 75 and the connection between these members is made in the following manner. Fixed to the upper end of spindle 92 is a coupling 93 having a transverse slot 94 in its upper end. A similar coupling 95 is fixed to the lower end of the shaft 96 of the armature of motor 75. A. driving link 97 of rectangular cross section extends between the couplings 93 and 95 and has its ends received in the slots 94 and also has central projections 98 on its ends to enter the ends of the holes in the couplings to retain the link from lateral displacement in its slots. This sort of a connection is the equivalent of a universal joint and eliminates the necessity for precise alignment of shaft 96 and spindle 92.
Above the motor 75 is a control panel 100, in the nature of a. horizontally disposed bracket having legs 101 which are suitably and preferably permanently, secured to the peripheral wall of tank 10. Mounted on this panel are all the devices needed to control the operation of the machine. These devices include an attachment plug device 102, for connection to a source of electrical supply, and a switch 103 which are connected electricallyin circuit with motor 75 b means not shown so that switch 103 wil control the starting and stopping'of the motor 7 5.
For controlling valve plug 87,,an operating handle 104 is rotatably mounted in panel 100 and its lower end is connected by yoke '105 to the flanged end of plug 87,this yoke being bent to clear the motor 75 and so attached to the plug that when the connection to handle 104 is removed the yoke may be swung outwardly to clear panel and permit removal of the motor and pumping unit. For yieldingly holding the valve plug 87 in either of the two-positions it may assume, the following device is employed. A wire clip is bent up in the form shown in Fig. 8 to afford a central straight portion 106 with two portions 107 diverging from its ends. The ends of the 1ast-named portions are bent backwardly upon themselves, forming portions 108, intermediate the ends of which are substantially semi-circular porclosely adjacent the yoke when in" t ese respective positions. In order to move from one position to the other th yoke must en gage the corner of the clip which connects these portions and in order to pass this corner the clip or the yoke, or both, will have to be deflected to permit this action, whereby the yoke is retained in the positions mentioned except when intentionally moved e springs-79. The yoke.
ositions than the drain pipe is turned in the other direction. The '01;
er portion 108 has a similar but smaller eye 111, which receives and guides a stem 112. This stem is fixed to a float 113 which is received in the reservoir 45. The upper end of stem 111 carries an indicator portion 114 which is slidably received in panel and may be read with reference thereto to determine 'the'level of water in the reservoir.
For the purpose of filling the reservoir, an opening 115 (Fig. l) is provided in the panel 100 and a curved pipe 116 connects this opening to the interior of tank 10. The space between panel 100 and the upper end of the reservoir forming portion 0 casting 40 is preferably enclosed, as by a sheet metal hood 117, which preferably is provided with louvers 118.
The drain pipe 86, heretofore mentioned, is rotatably seated in the casing 83 in an suitable way and passes upwardly through panel 100 terminating slightly thereabove. A smaller pipe 120 is inserted in the upper end of pipe 86 and united thereto by sweating it in. This ipe 120 is bentvto form a long nozzle whic may be swung from the osition shown in Fig. 1 to that shown in ig. 2, in which latter position the outlet end of the nozzle projects sufficiently beyond the machine so as to overlie a sink .9 when the machine is wheeled closely adjacent thereto. Thus, when so positioned and when valve 87 is turned to connect the chamber 88 to pipe 86, substantially the entire liquid contents of the machine may be ejected into the sink and thence to the sewer.
The pipe 86 (Fig. 7) has a slot 121 therein into which a screw 122, threaded into panel 100, extends. The circumferential extent of slot 121 is sufiicient to permit the described angular range of movement of nozzle 120, and the interengagement of the screw and slot limits: the angular movement of pipe 86. Such interengagement also acts to hold pipe 86 against vertical displacement and yet permits the pipe to be conveniently removed by lifting'it vertically when the screw is withdrawn from the slot. The slot 121 may be cut entirely through pipe 86 for j the pipe 120 is inserted far enough into the latter to close the slot against leakage. Preferably, pipe 86, unless machined to closely fit the I ole in panel 100, is grooved to receive a friction ring 123 which bears against the wall of the hole through which pipe 86 passes and prevents it from rattling under the vibrations set up by motor 75.
In order to permit the reservoir of the machine to be conveniently filled from the faucet, such as the hot water faucet shown in Fig. 2, I provide a flexible hose 124 which carries at one end a nozzle 125, for insertion in hole 115 of the control panel. The other end of hose 124 is connected to faucet f and I prefer to provide a device for this purpose which may be left attached to the faucet and yet permit the latter to be used in the ordinary manner for other purposes when desired. To this end, I provide the device shown in Figs. 21 and 22 which includes a bracket made in two parts-127 and 128 adapted to be clamped together and to the nozzle of faucet f by screws 129. Pivoted to member 127, at 130 is a bracket 131 made up of stiff wire bent to form a loop 132 and having in the two end extensions of this loop eyes 133 through which pivot 130 is assed. Beyond e es 133 are projecting end s 134 which are a apted to be engaged by the free end. of a fiat spring 135 fixed at its other end to member 127. An elbow 136 is received in loop 132 and is preferably free to rotate therein. One end of elbow 136 is connected to hose 124 and the other end has a funnel portion 137 formed therein to receive the outlet end of faucet f. Such funnel forms an exterior shoulder on the elbow to engage loop 132 which is received and closely fits between such shoulder and a bead 138 on elbow 136. The elbow 136 may be swung from the position shown in full lines in Fig. 22, wherein funnel 137 fits over the mouth of faucet f, to the position shown by dotted lines in which the funnel is removed from the path of water issuing from the faucet. When in either position, the spring 135 acts on projections 134 in such a manner as to releasably hold it in such positions and when in the first named position the spring may be utilized to swing member 132 toward the faucet, and if desired, press the funnel 137 tightly against the mouth thereof.
As a desirable adjunct to the machine, I may provide in addition to the screen associated with the opening 41, a second screen and so arrange these screens that either may be brought into play, as desired. The idea of this arrangement is to allow one screen to function during the washing operation and the other during the rinsing operation, and to arrange the screens so that the clean rinsing water may be revented from passing over the accumu ations on the first named screen. This result may be accomplished in any suitable way, and as an illustrative example, the structure shown in Fig. 23 may be employed. Slidably mounted in into the illustrated position,
Opening 41 is a ring like frame 140, which at high speed to force thewater through the is provided intermediate its ends witha plurality of openings 141 in its circumferential wall. Above these openings, a screen 142 is provided to cover the upper end opening of frame 140, and below these openings, a similar screen 143 is mounted in a similar way. A shield 144 overlies the screen 142 and is supported in spaced relation with the latter from frame 140, so that water can reach screen 142 between the shield and screen but cannot descend directly upon it from above. To the lower end face of frame 140 a spider 145 is secured, and this spider is supported in the free end of a lever 146 140 may be lifted sufliciently to raise screen 142 above the level of water in tank 10 and allow the openings 141 to communicate with tank 10, so that water from the tank enters these openings and passes through the lower screen 143. To hold the frame 140 in lifted position, any suitable means may be employed, such as the spring latch 149 shown in Fig. 24, which is adapted to engage in under panel 100 when the rod 148 is depressed and releasably hold the latter in depressed position,the latch being releasable to permit rod 148 to be moved upwardly when desired, by pressing it toward rod 148.
In using the machine, it may be wheeled into the dining room adjacent the table and there loaded with the articles to be washed.
The cups, glasses and bowls are placed mouth down on grid G and larger bowls, tureens .and so forth may be placed over them. if desired. The knives, forks and spoons are placed on end in silver holder S water, preferably and most conveniently by.
utilizing the device shown in- Figs. 21 and 22, and the operator can readily tell by the indicator 114 of the float gage when the properamount of water has been supplied. The electric connection is then made to the ,device 102 and switch 103 closed to start the motor, whereby screw 91 is set in motion tubes of the spray rotor. lVater issuing from the latter through nozzles 64 causes the rotor to revolve and the jets from nozzles 60, 60, 64 and engage the dishes in the manner heretofore described in detail. An operation of the machine for two or three minutes is usually sufficient to thoroughly wash the dishes. The nozzle 120 of the drainpipe 86 is then swung over the sink a and the handle 104 turned to cause valve 87 to connect chamber 88 with the discharge pipe. whereupon the washing water is ejected into the sink. The valve 87 is then reset to its former position, the machine refilled with clean hot water, and again operated for a minute or so to rinse the dishes. The rinsing water may then be discharged from the machine, as already described, or it may be left for subsequent use as washing water if another batch of dishes is soon to be washed The motor is then stopped and the dishes allowed to drain, the cover being first lifted to dissipate the steam. After the dishes have become thoroughly dry, the machine may be wheeled to the china closet and the dishes removed.
