' 6 Claims. (Cl. 134-99) thede'vice also employing a drying mechanism for circulating heated filtered air through and around the articles that have been cleaned.

The invention further contemplates a washing apparatus that defines an open frame formed by perforated Separate tubes and couplings therefor and with novel means of connecting each of the tubes to perform first, a washing action, then a rinse action and then a distilled rinse, permitting thewasher to reciprocate and still maintain connection with the respective sources of fluid supply. A further object of the invention resides in a novel form of means to continuously drive the washer in its reciproeating movement and at the same time permitting the flow of the sevcralfluid mediums through the respective tubes of the washer. j, A further objectof the invention resides in a washing and drying apparatus having a reciprocating washer head whereby the cleaning and rising fluids are ejected to impinge ,upon the articles to be cleaned within a basket supported upon fixed rails and whereby the head is adapted to spray the cleaning and rinsing fluids upon the articles from the sides, the top and the bottom and with a cabinet supporting the mechanism having doors at its front and back walls, to constitute a pass-through cleaning device.

A further object of the invention resides in a novel form of storage tank and means for controlling the flow from a drip pan spanning the casing and means to direct the: drainageto adjacent compartments within the tank. Novel.;features of construction and operation of the device w'ill be more clearly apparent during the course of the following description, reference being had to the accompanying drawings wherein has been illustrated the preferred form of the device and wherein like charactersof reference are employed to denote like parts throughout the several figures.

Patented Mar. 29, 1966 ice on line 99 of FIGURE 7 and illustrating control means for a valve.

Referring specifically to the drawings, there has been illustrated a cabinet having a front wall 5, a rear wall 6, a top wall 7 and a bottom 8. The cabinet may be formed of any desirable construction, such as sheet metal and suitably braced against flexing. The walls 5 and 6 are provided with closure doors 9, hinged or otherwise supported, as is customary. 1

Mounted in the upper portion of the casing and within a chamber 10, is a reciprocating washer device, indicated as a whole by the numeral 11. The Washer device, see particularly FIGURE 3 is formed ofcylindrical tubes 12, 13 and 14 and these tubes communicate with couplings 15 which constitute the corners for the washer and con- The tubes are all perforated in a direction toward an area that-is defined by the washer. The lower couplings 15 are adapted to ride upon angletrackways 18. It will thus be apparent so far as the structure has been described that the washer 11 forms a box-like open structure. Spanning the length of the casing are fixed bars 19 constituting a support for a foraminous basket 20 into which is placed the articles to be cleaned.- The Washer reciprocates back and forth upon the tracks 18 and each of the tubes are perforated to spray the various mediums over the articles in the basket.

Each of the forward lower tubes of the washer are connected by couplings 21, 22 and 23, each of the couplings communicating with their respective tubes. Each of the couplings are connected to a source of fluid supply by elongated tubes 24, slidable within a cylinder 25 and with the tubes 24 having seals 26 to prevent the escape of fluid passing therethrough. The cylinder 25 is fixed to a coupling 27, communicating with a vertical supply pipe 28. The structure just described is typical for eachv of the couplings 21, 22 and 23 with the exception, that the pipes 28 lead to their respective sources of fluid supply, such as a wash solution, a rinse solution and a distilled rinse. 1

For the washing cycle, there has been provided in the lower part of the casing with a supply tank 29 carrying a heater element 30 and a pump 31 createsa flow of washing fluid from the tank 29, through the pipe 28a, the stand pipe 28, through the coupling 27, tube 24 and hence to the pipes 14, Where the washing medium is circulated through the several corresponding pipes 14 to be supplied outwardly, downwardly and upwardly upon the articles in the basket 20. This washing cycle is operable during the reciprocating movement of the washer 11 and after a predetermined washing cycle, it becomes necessary to initially rinse the articles and this is performed by a source of pressurized rinse medium from a suitable supply, to a pipe 32, controlled by a solenoid valve 34 inthe pipe 35 and the pipe 35 has a corresponding stand pipe similar to the pipe 28 and to the plumbing arrangement shown in FIGURE 4 and to the pipes 13. A filter 36 may be installed within the pipe 35 as will be apparent. After the apparatus has performed its rinsing cycle, it now becomes necessary that the articles within the basket be subjected to a distilled rinse. For this purpose, there has been provided a pump 37, receiving a supply fluid through a pipe 38 from a suitable tank or other storage means and this distilled rinse is pumped through a pipe 39, past a filter 4d and then through its particular stand pipe 28 to the Washer tubes 12, circulating through the corresponding pipes 12 throughout the structure of the washer, thoroughly rinsing the articles with a distilled rinse medium. The tank 29, see particularly FIGURES 7 and 8 is provided adjacent one end with a partition 2%, forming chambers A and B. The partition 29a does not extend to the top of the tank, as will be clearly apparent in FIGURE 8. The fluid from the drip pan 44 is drained downwardly into the tank 29 through a pipe 41 that communicates with the chambers A and B. The drainage fluid from the pipe 41 may be directed into either the chamber A or B by a fiat valve 43, that is fixed to a cross shaft 44 and the shaft is rotatable to cause theflat valve 43 to overlie the partition 29a and to direct the drainage fluid into the tank A or, when the valve 43 is in the opposite direction, to drain the fluid into the chamber B for disposal through a drainage coupling 41a. The drainage pipe 41 is disposed over the valve 43 and permits the drainage to enter either the chamber B or the chamber ,A and to thereby prevent the diluting of the fluid in chamber A or to prevent too great a cooling of the washing fluid; The means to rotate the shaft 44 comprises a motor 44a, having a linkage connection to a crank arm 44b, fixed upon the shaft 44 and with the motor and the linkage being within a fixed housing 29b, welded or otherwise connected to one side of the tank 29. The motor 44a at a predetermined cycle, actuates the linkage to shift the valve 43 in one direction,- to cause the drainage fluid to fall downwardly and enter the tank chamber A and,'when the motor is deactivated, the parts are reversed by a spring 440, causing the drainage fluid to enter the chamber B for discharge through the drain 41a.

Means are provided to reciprocate the washer 11, comprising ,a rod 45 that is coupled at one end to a bracket 46: fixed to the lower flights of the tubes 12, 13 and 14 and whereby to shift the washer in a back and forth manner uponthe rails 18. The rod 45 at its rear end is fixed to a bracket 47, carrying grooved rollers 48, adapted to traverse flanges 49 on a box-like housing 50. The housing 50 is connected to one vertical wall 44 of the drainage pan 44 while its opposite end is connected to an end wall of the casing 6. Journaled within the housing 50, is an endless chain 51, carrying a lateral pin 52 that engages a vertical slot 53 formed in the bracket 47. The chain 51 engages sprocket wheels 54 and 55 that are suitably journaled within a wall of the housing 50 and the sprocket 55 is preferably driven from. the motor 56'. With the motor 56 in operation, driving a sprocket chain or belt 57 to the sprocket 55, the chain is shifted around the sprockets, causing the pin 52 to actuate the bracket 47 substantially for the full length of the housing 50, causing the rod 45 to oscillate the washer 11 in a back and forth manner over the basket 20, subjecting the entire group of articles in the basket to a thorough clean irig action. As the chain 51 is driven, the pin 52 rides up and down in the groove 53, carrying the bracket 47 in a back and forth movement along the flanges 49.

Means are provided after completion of the washing and rinsing cycle to thoroughly dry the articles within the basket, comprising a blower 58, connected by hood 59 to a conduit 60. The conduit 60 is provided with heating elements 61, a pie-filter 62 and a final filter 63.

The conduit communicates with a vertical conduit 64 formed by the side wall of the casing and a partition into the upper chamber 10 through a closely perforated wall 66 whereby to disperse the heated air throughout the chamber 10 and in and around the articles within the basket. The heated air then passes through a closely perforated baffle 67 and upwardly to be discharged through a stack 68. The baflle 67 and the adjacent side wall of the casing constitutes an escape duct 69 for the air after it has performed its function. It is contemplated that the perforated partition 66 and the baflle 67 shall extend for substantially the full depth of the machine. All of the component parts, including the pump 31, the pump 37 and the actuation of the solenoid valve 34 shall be suitably timed by any desired timing mechanism and a time control means for the blower 58 will also actuate the blower after the washing and cleansing action.

In the use of the device, the access doors 9 are opened and the basket 20 carrying the articles to be cleaned is rested upon the rails or rods 15*. The motor 56 is then actuated causing the chain 51 to shift the bracket 47 and the rod 45 in a back and forth manner, moving the entire washer assembly in a direction lengthwise of the casing. The pump 31 being then actuated, forces the washing fluid through its respective pipes and the tube 24 to force a pressurized wash medium to the series of tubes 14, spraying the washing medium laterally and downwardly and upwardly upon all of the articles within the basket. After the washing cycle, the solenoid 34 is actuated to permit pressurized rinsing medium to flow through its respective pipes to the series of pipes 13, suchbeing identical to the structure illustrated in FIGURE 4. Upon a predetermined number of reciprocations of the washer, the solenoid closes and the pump 37 is then actuated, forcing a distilled rinse fluid upon the articles in the basket; After the predetermined distilled rinse motions of the washer, the blower 58 is brought into operation forcing heated and filtered air through the conduit 64 and downwardly andthrongh' the perforated parti; tion 66, flowing transversely of the chamber 1-0 and after impingement upon the articles in the basket, the air becomes cooled andescapes through the perforated baflle 67 to escape upwardly through the duct 69 and out of the stack 68. It will of course be apparent that a system of cycle control will be installed for the several elements so that the operation is continuous and uninterrupted throughout the washing, rinsing and distilled rinse and then the drying. The various electrical components will all be controlled for the complete cycles of movement of the washer and the drying of the articles. The device is relatively simple, and is highly effective for thoroughly cleaning, rinsing and drying of articleswithin the removable basket 20. As will be seen in FIGURE 2, the washer 11 overrides and underrides the basket 20 and is mosteflective for the cleaning of the articles upon all of their surfaces. I

It is to be understood that the invention is not limited to the precise construction shown, but that changes are contemplated as readily fall within the spirit of the invention as shall be determined by the scope of the subjoined claims.
