To all whom it may concern:

Be it known that l, AN'ronG. ScHMnLzEn,

born in Hungary, of Hungarian parents, now believing myself to be a citizen of that country, and having formally declared my,

According to one feature of my invention, I provide a machine with mechanlcal means to circulate or deliver washing and rinsing water during predetermined periods in the cycle of operation of the machine and a mechanical means. to automatically" stop the flow of washing and rinsing water at predetermined times.

According to a further feature of the inp vention a dispenser for soap or the like is provided and such dispenser is arrangedfor actuation from the door of the washing compartment, to the end that a measured charge of soap or'the like is automatically delivered into said compartment each time the door is opened and closed.

According to another vention, 'an improved sprinkler pipe construction is provided for use in a machine s of the type described... v

' Other features and adva'ntageswill appear in the following description and in the illustrative embodiment of the invention in the accompanying drawings, in which:

Referring to these drawings with particular reference to Figs. 1 and 2; it will view taken.

be seen that my machineponsists, in general,

pf a casin 9 in which are located the washmg and rlnslng sprinklers and in which the articles to be washed are adapted to be laced. A'soap dispenser 10 is associated with the upper portion of the casing'9 and the control and circulating mechanlsm for both the washing and rinsing water systems are located beneath thecasing and enclosed by a cover 11. The casing 9 is supported by. spaced apart supports 13 secured to the lower. side of the casing by suitable bolts and'are maintained in a spaced relation at their lower ends by a tie rod 16.

The casing 9 of the machine is'be'st shown in Figs. 1 and 2 and hason its front side a rectangular opening 20. A sliding door 21 is constructed and arranged to slightly overlap the opening on its four sides and caused to lie snugly against the face of the casing by the lip portion 22 thereon. This door, which is arranged to slide upwardly Yfroma closed to an open position is counter weighted to allow it to remain in either an open, closed or intermediate position. Thus, counterweights 23, which slide freely in hannels 24 of the casing 9, are connected to the door by flexible cords or cables25 and the cords are run over suitable grooved guide sheaves 26. The door is further provided with a spring pressed pawl 27 inits upper corner, as. shown in Fig. 1, which pawl forms a jac is adapted to engage withthe soap dispenser p as will later be described. The lower pprtion of the casing 9 is designed to serve as a water reservoir, as at r. In this reservoir 1' is located a removable filter 28, which is placed directly over the pump inlet 29 (see Fig. 3) and a removable overflow nozzle 30, which is located directlyover an overflow pipe 31 (see Figs. 2 and 3).

A hollow cover 38 surmounts the open top of the casing and provides a tank 39 which 9 for purposes to be hereinafter described. This cover is suitably secured to the casing as by bolts 40. The cover 38 supports the soap dispenser '10 and has an enclosed channel 41 located directly under the 'outlet of Y the soap dispenser (see Figs. 6 and 7) to convey soap or the like to the interior of the casi 9. A water inlet 42 and a water out-- let 43 are located at opposite ends of the cover 38f0r purposes to be later described.

A plurality of idler rolls 45 are rotatably mounted in the side rails 46 which are sup ported by projections 47 on'the interior of. casing 9 and, as will be seen by reference to Figs. 1 and 2, are so arranged that the rolls.

are held approximately in line with the bottom edge of the door opening. These rolls are provided for the purpose of receiving and supporting trays containingthe articles to be washed.

The washing sprinklers 50 and 50 and partment, and along the rear side thereof, is]

a suitablsupported header member 52, from wh1ch" a plurality of sprinkler pipes 50 extend forwardly in spaced parallel relation toward the cover 21. The pipes 50 constitute the upper set of washing'spri'nklers. Adjacent header 52 is a similar header 53 from which a plurality of pipes 51 radiate similarly to the pipes 50 described. Pipes 51 constitute the upper set of rinsing sprinklers. The lower sets of washing and rinsingsprinklers are designated 50 and 51 respectively and are mounted on headers 52' and 53' respectively in a similar" manner to that already described. The lower sets of sprinklers are arranged above the series of rolls 45 described. I

Each of the sprinkler pipes 50, 50, 51 an 51? is provided with a plurality of nozzles 54 arranged in longitudinally spaced rela the spreadin ted upper wall for the casing.

ncomes tion. Each nozzle, as shown in Fig. 8, is rovided with a threaded portion whereby it may be removably secured to its sprinkler pipe. The openings 54' through the nozzles are enlarged at their outer ends to facilitate action of the water, as shown b the dotte lines. As will be seen the nozz es extend to a considerable distance into the sprinklers and are purposely so extended toprevent foreign matter contained in the water from being forced through the open ings 54'. An elbow 55, in threaded enga ement with the-outer end of each sprink er pipe, is provided with a valve56, as shown. The'valve 56 normally seats against a suitable seat on the end of its sprinkler pipe and 6 thus closes such end. This valve normally is in clwed position as shown and may be opened 'by turning the shank portion56' at such times as it is necessary to clear the sprinklers of foreign matter or the like. 1

The washing sprinkler headers 52 and 52'.

are'suitably connected to a vertical riser 60 formed on the rear right hand corner of the.

casing 9 as shown in Fig. 3. The rinsing sprinkler headers 53 and 53 are suitably connected to a riser 63 formed on the rear left corneroit casing 9, as shown in Fig.3. The lower header 52 is suitably swivelled in a support 61 whereby it may be swung np-- wardly from the illustrated position in an 'obvious manner thus raising the intermediate spray pipes 50 out of the way when cleaning the tank 7*, the end spray pipe being preferably mounted directly in support 61.

The lower header-53 is similarly mounted for swinging movement but is pivoted'to the opposite side of easing 9.

For the purpose of ositioning the arti- "cles to be washedin a ocation between the top and bottom sprinklers a tray 65 of wire mesh is provided. Such tray is supported along two edges by a U-shaped support 66, as best shown in Figs. 1 and 2. The support 66 is adapted to he slid into the wash 'ing. compartment with the flat bottom pant of the support riding upon rollers 45. In the upstanding parts of the support 66 and closely adjacent the bottom part thereof are longitudinal openings 67 for the purpose of allowing water and foreign matter to quickly escape from the bottom of the support along both ends as well as along the open sides thereof. The open sides of the support permit the support with attached tray to be slid into place in the washing compartment without moving the lower sets of sprinklers andyet support the articles to be washed above such lower sets.

The water distributing and circulating apparatus .will now be described; with particular reference to Figs. 3, 4, and 5. An

electric motor 70 is suitably attached to the under side of the casing 9 and'has extending therefrom in opposite directions two shaftsto the shaft 83 -71 and 72. In axial alignment with the the in such a position as to nee les motor is a suitable pump p, preferabl of the centrifugal type, and the driving s aft of pump is connected by a rigid poupling 73 to the shaft 71 of the motor 70. A gear box 74 is also attached to the casing 9 hous ing a suitable speed gear reduction mechanism, exemplified in part by the gears 74' in Fig. 3. The driven end of such mechanism' is in alignment with the motor and connected to the shaft 72 of the motor 7 O. This mechanism may be of any suitable type which is capable of effecting a considerable speed reduction and. .it has beenthought unnecessary to illustrate the mecha-- nism in detail. In this instance, for example, it is proposed to use a; mechanism capable of reducing from a motor speed of approximately 1700 revolutions per minute to a speed of one or lessrevolutions per minute.

A shaft 75 extends from the driving end of the gear box 74 and is arranged to lie in the same plane with and parallel to the axis of the motor 70. This shaft 7 5 is rotatably supported in a bearing 76, which is secured to the under side of the casing 9, and fixed. on shaft 75 and adjacent the bearing 76 is a clutch cone77. A clutch disc 78 is loosely mounted on the shaft 75 and is adapted to engage, and be driven from, the clutch cone 77. This disc is also provided with a spiral spring 79 contained within an axial recess provided. therefor, and this normally hold the disc 78 and cone 77 from frictional engagement. The disc 78 is further provided with a bevel face '80 with which a valve lever may engage, as will later appear, to slide the disc longitudinally along the shaft 75 and thus bring the clutching faces into frictional engagement. Projecting pins 81 and 82 extend from the opposite faces of the clutch disc 78 (see Fig. 3) and are arranged to operate valve levers. as will later be described. A rocker shaft 83 is rotatably mounted in bearings 84 and has secured to one end a lever 85, which lies adjacent one face of the clutch disc 78 and raised at predetermined times by the pin 82 of thedis'c 78. A pawl 86, best shown in Fig. 5, is also fixed (Fig. 12) near its other end, and, of-course, swings uniformly with the lever 85. A pawl 87, similar to the pawl 86, has a sleeve 87 fixed thereto which extendsthrough the left hand bearing 84 and is loosely mounted on shaft 83. To the left 7 of the sleeve 87 is secured a lever 88. The

lever 88 lies adjacent the other face of the clutch disc 78 and is arranged to be raised by'engagement with the pin 81 of'the disc. Thus it will be seen that as the clutch disc rotates the pins 81 and 82 thereon are arranged to raise the levers and 88 respectively which will raise simultaneously spring acts to.

the pawls 88 and 87 for a inafter described.

The water system-may be divided into two groups namely, a washing and a rinsing system. The washing system will first be described. The pump 1) previously referred to, -is secured to the bottom of the casing and has its inlet 29 arranged directly under the filter 28 already described. Its outlet 90 extends from the bottom and is connected by suitable connections to the T 92. Directly over the T 92 a check valve 93 is placed for a urposeto be hereinafter described.

, uitable connections 92' connect the T 92 with a valve V. The latter is clearly shown in Fig. 10 and includes a valve element a and purpose to be hereattached stem 5,'which element is normally as follows, viz., through T 92to valve V, through connnec and conducted and tions 9% to riser 60 and into sprinklers 50 I and 50 from whence it is forced through the nozzles 54: at suitable pressure dependent "only upon speed of pump p. 3

The rinsing system designed to furnish clean and unused water will now be de-' scribed. A pipe 95, connected with any suitclosed'by similar means. A pipe 99 and suitable'connections join the valve 0 to the rins- 100 able water supply (not shown) is. connected pipe98, (seeFigs. 3, 4 and 11) is ing riser 63 and delivers the water to the sprinklers 51 and 51. Thus it will be seen that the rinsing Water is conducted in the following manner, viz, from its source through pipe 95 into tank 39, from tank 39 to heater H from the heater through pipe 98 to valve '0, thence to riser 63 and headers 53 and 53' then into sprinklers 51 and 51.

The valve V of the washing system and the vaive 1) of the rinsing system which are normally closed are arranged to beopenedin the following manner. As will be seen by reference to Fig.5, each valve is provided with a lever 10A, arranged to be engaged by the pawls 86 and 87 to hold the valves in an open position. As heretofore des'cribed these valves V and 'v are closed by a spring (such as 2'2) within the valve and, when so closed,

'the levers 104 assume positions such as extends transversely to lie beneath and-enplish this purpose,

- reservoir 1', for the purpose as gage with both valve levers 104 when such levers are in the described dotted line position. On lifting the lever 105, both levers 104* are raised and are caught and retained in an open position by the pawls 86 and 87." The valve lever 104 of valve 1; is provided with a projection 107 (see Figs. i, 5, and 10) which when the valve is o ened engages the bevel 80 of the clutch disc 8 and causes this disc to slide along the shaft 75 and engage the cone 77.

The foregoing description discloses the apparatus for the circulation and control of the Washing and rinsing during a washing or rinsing operation, but at such times as the machine is being supplied with articles tor-be washed it is desired that no water he allowed to flow through the sprinklers. The valves V and 'v, of course, are closed during this period and as the pump p is running at all times the discharge therefrom is desirably conducted to the tank 7. To accomll provide directly over the T 92 a check valve 93 (see Figs. 3 and 4) which is of a well known type such as will remain closed under a head but willopen with pressure applied to its inlet, when said pressure is in excess of the head on its discharge end. An illustrative example of one suitable typeof check valve is shown in Fig. 13. Suitable pipe connections 109 connect the-valve 93 with the reservoir 1' and allows of a free circulation of water from reservoir 4 through pump 11 and back to hereinbefore described.

In operation. 9. is supplied with water of any desired temperature and water from a suitable source of supply is admitted to the tank 39 through the pipe 95. Water in the tank 39 flows through the discharge pipe 43 to a heater or the like and is returnedto the machine by the pipe 98. The waterthus returned to s the machine is,raised to any required temperature by the heater and delivered in a volume under suitable pressure. There 'being suitable water in the reservoir. 1- the door 21 is raised to an open position and in so raising ,the springpressed pawl 27 of the door is carried to a location above the ratchet wheel 10 of the dispenser. The door,

when in an open position, allows the tray 6-3 with its attached support 66 to be passed through the opening 20 of the casing9 and placed upon t e rollers 54;. The door 21 is 'now closed and, in lowering the door to a closed position, the pawl 27 thereon engages the ratchet wheel 10' of the soap dispenser 10. This engagement will turn the ratchet the reservoir '1' of the casing dispenser and deliver through the channel 41, (see Fig. 6,) whatever soap powder, or the like, iscontained withina compartment of'the pocketed wheel. This soap will fall and also the pocketed wheel 10 within the to the Water in the reservoir 1' of the casing 7 9 when it will be taken up and dissolved by the water. At this oint the motor is set in operation and rives the pump p and shaft continuously, and until the current thereto has been disconnected.

It is now desired to commence the washing and rinsing operations and the valve V of the washing systems and the valve 2; of the rinsing systems are simultaneously opened.

It will here be noted that the opening of the valve 42 of the rinsing system causes the clutch cone 77 and disc 7 8 to be moved into clutching engagement and the now rotate with the shaft 75. will thus remain in clutching engagement until the valve 0 is closed, at which time the spring 79 will disengage the clutch members. a

The valves, having sufficient washing water having been applied to the articles being washed, it is required to close the washing valve V. This is accomplished by the pin 82 of the rotatdisc 78will The clutch 85 thus been opened and ing disc 7 8 abutting and raising the lever 85,

The valve thus being closed, no further water will be pumped to the washing sprinklers. 50 and,50' and, since the pump is in continuous operation, the water is now I pumped u through the check valve 93 and The rinsing pipe 109 to the reservoir a. water, now'being forced through the sprinklers, removes soap and other substances left v continues rinsing them until the valve 2) is closed. This valve is closed in a manner'si'milar to the closing of. valve V, and is accenaptished by the pin 81 of the rotating disc 78 engaging. and raising the lever 88. I

Thus Ihave provided improvements in on the articles and washing machines which are particularly designed for the washing of numerous and divers articles such as glasses, receptacles or the like. It is obvious that modifications may be made in-the device as herein described for illustrative purposes and I therefore prefer to have the scope of my invention defined by the appended claims rather than by the foregoing description.
