To all whom it may concern Beit known that I, ARTHUR T. HAennjof Rochester, in the county of Monroe and.

State of New York, have invented certain new and useful Improvements in Valve -Mechanism' for Washing Machinery; and Idol-hereby declare the'following'to be a full, clear, and exact description of the same, reference being had to the accompanying tion, and to the reference numerals marked thereon.- 3

The present invention hasfor its. chief purpose to provide a. valve mechanism applireceptacle of its liquid contents at stated intervals. Ina more specific aspect, the invention consists in simplifying the construction and operation of this class of devices generally and in correlating the inlet and outlet valve mechanisms for the water'so as to effect automatic control of the machine. A further purpose of the invention resides in the provision of an arrangement whereby a single operation is all that is required'to efiect emptying the receptacle of its contents and subsequently filling 1t with-fresh liquid to a predetermined point, such operation being dependent upon the opening of an outlet valve which permits the discharge ofthe contents ofthe receptacle and results in the subsequent closing of said valve and opening of an inlet valve that'efiects filling :of the receptacle up .to a predetermined level after types of machines and -embodies--generally which the inlet valve is automatically closed.

To theseand other ends the invention conf sists in certain improvements-and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the 9'5 I specification.

The invention. is applicable-to difierent inlet and outlet valves connected to a liquid receptacle andforming the means for sup- {plying liquid to and discharging it from the receptacle, together with provision for manually operating the outlet valveto empty the receptacle. Mechanism is provided-for determiningthe operation of the inlet. valve, and isconnected to the'operating means'for the outle't valve in such a manner as to 'efi 'ect'closing of the outlet valve when the receptacle is emptied .ofits con-- tents and thereafter to automatically open sequently determined when the level of water in the receptacle reaches a predetermined point.

In the present arrangement, I have shown the improvements in their application to a clothes washing machine of standard type,

such as embodies a receptacle 1, having supporting legs 2, and mounted on a concrete or other oundation 3, having a gutter 4 to carry ofl the liquid when discharged from the receptacle. 5 designates the inlet pipe leading from the valve casing 6 to which are connected hot and cold liquid supply pipes 7 from which the receptacle is furnished through the inlet pipe 5 according to the position of the inlet valves 8. The inlet valves 8 forhot and coldwater are both constructed and operated in the same manner and for convenience in the present application, I will describe only one of these.

Each valve 8 is of the balanced-pressure type and to this end carries a' piston 9 movable in a chamber 10 while the fluid pressure has access to the upper side of the piston through the passage 11 shown in Fig.

and carrying a valve stem 16 extending downwardly beyond the casing as shown-in Fig. 8. The casing 13 also includesa passage l7 connecting with the two ports controlled by the valves 15, and the'passage 17 leads to a discharge or outlet 18. Thus when the supplemental valves .15 are open, pressure'is released from the upper side of the pistons 9 so that the greater pressure on the under side of the piston elevates them and opens the valves 8 to admit water to'th e filled.

receptacle, and I will now describe the'means vfor controlling the position of the supple: mental valves 15.

19 is a bracket mounted on the valve,casmg-Gand arranged on this bracket is a controller for,'each supplemental valve 15 which preferably comprises a body portion 20' piv- .oted about the axis 21' and having a no e to be described presen y. The c ntroller also includesflan' extension 23 for engagement with the valve stem and an arm 24 22 extending into the iath of anactuat r projecting'intothe path. of a liquid controlled member to be described presently. Also arranged on the bracket 19' is a carrier pivoted at 25 and embodying upstanding arms 26 on which are movably mounted the weightedactuators 27, each one arranged to cooperate, when: in operative position, with 'thecorresponding' supplemental valve controller by engagement with its nose 22.

When the carrier is moved from the position shown in Fig. 5 to that shown in Fig. 4, the actuators 27 engage the noses 22 on the controllers, moving the supplemental valves thus permit thesupplemental valve and the corresponding inlet valve to remain closed. The carrier is provided with an arm 28 which is pivotally associated with a connecting rod 29, in turn connected to alever 30 carrying a treadle 3l.- 32 is the receptacle outlet in which is arrangedthe valve 33 having a stem 34 in the path of the tail piece 35 on the lever 30. When it is desired to open the outlet valve, the treadle 31 is depressed moving the connecting rod 29 downwardly at the same time,-as shown in Figs. 2 and 5. The outlet valve -is held open by means of a weighted lever 35 piv oted at 36 on an arm 37, and carrying an extension 38 provided with a roller 39 which engages the upper'end of the'connecting rod 29 in the manner shown in Fig. 5. The lever 35 is weighted at 40, to hold it in locking engagement with the rod 29 and also carries an arm 41, by which it is moved out of locking position when the receptacle is empty, whereupon the weight 42returns the lever 30 to its normal position permitting the outlet valve to close by gravity, and at the same time the carrier moves so as to operate the controllers and o enthe supplemental valves as shownin Fig. 4, to permit the receptacle to fill. I will now describe the liquid controlled means whereby the operation just described is eifected when the receptacle is emptied, and the inlet valves are closed when the receptacle is 43 designates a float chamber connected with the receptacle by the pipe 44 and 45 is a float movable in thechamber 43 and carrying the vertically extending guide 46 having a flange 47 atits upper end arranged. for engagement ,with the arm 41 as shown in Fig. 5. Adjustably arranged on thelguide 46 is ;a pair of stops 48 provided withspring actuated clutches 49- for holding them. in adjusted position. v The stops 48 are. ar-v ranged-.forengagement, with the arms 24 on mitting the supplemental valves and the in- I let valves to close and thus ,cutting off the supply of fresh liquid to the receptacle, and

' the guide, the time of closing the inlet.

' themes by changing the position of the stops 48 on valves can be adjusted to determine the proportion of cold and hot water that is supplied to. the receptacle.

The operation of the structure is briefly as follows: Assuming the parts to be inthe psition shown in Fig. 3, the guide 46 is in its lit) uppermost position, the receptacle is filled' to the normal level, and the valves are all closed. 1 When it is desired to empty the receptacle, treadle 31 is engaged and forced downwardly, elevating outlet valve 33 and lowering connecting rod 29 until the parts assume the positions shown in'Figs. 2 and 5, where the extension 38 on lever engages the upper end of connecting rod 29, holding it lowered, and the carrier has been moved on its pivot until the actuators 27 are carried past the noses 22 on the valve controllers, as shown clearly in Fig. 5. As the liquid is discharged from the receptacle, float 4:5 is lowered in the float chamber, causing the guide 46 to move downwardly, at which time the. flange 47 engages the arm 41 on lever ,35, and as the float reaches the limit.

of its downward movement, the lever 35 is rocked about its axis far enough to release the'rod 29 permitting the latter to return to its normal position as. in Figs. 1, 3 and 4:. This operation also forces the actuators 27 laterally until they engage the noses 22 on the valve controllers, moving the latter to the positions shown in Figsl, l and8, and

opening the supplemental valves. This releases pressure on the upper side of the pistons 9 and permits the inlet valves toopen, letting in a supply of fresh water, the proportion of hot and cold being varied, to suit the demands of the machine by adjusting the stops 48. if only hot or cold water is desired, the corresponding actuator 27 is moved to its inoperative position sothat the cor responding inlet valve remains closed. As

. the receptacle is filled, the float again rises in its chamber until the stops 4-8 engage the arms 24 on the valve controllers, moving the latter from the position'shown in Fig. 8 to that shown in Figs. 3 and 5, and thus closing the inlet valves. The parts are then in the position appearing in Fig. 3 and ready for another operation.

The particular construction that T have described is not to be considered as the only means for accomplishing the purposes of my improvement and it wil1 be understood that the present application is intended to cover any modifications or departures coming within the spirirnand purpose of the invention as set forth in the claims.
