Specification of Letters Patent.
Patented July 14, 1914.
Application filed January 2.6, 1914. Serial No. 814,389.
anism of peculiar construction, whereby the flow of water into the washing machine may be controlled automatically in accordance with the depthof water therein.
A further object of the invention is to provide a peculiar means for determining the temperature of the water to be delivered into the machine.
The foregoing and other objects of the invention will hereinafter be more fully described and claimed and illustrated in the drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which I Figure 1 is a side elevation of a valve casing made in accordance with a preferred form of the invention; Fig. 2 is a horizon talsection of the same substantially on the line 22 of Fig. 1; Fig. 3 is a transverse section on the line 3+3 of Fig. 2, but indicating the movable valves removed; Fig. 1 is a view of the movable valve casing; Fig. 5 is atransverse section of the same on the line 55; Fig. 6 is a view on the line 66 of Fig. 2; and Fig. 7 is an end elevation of a washing machine showing our improvement attached thereto.
The several parts of the device maybe made of any suitable materials, and the relative sizes and proportions, as well as the general design of the mechanism, may be varied to a considerable extent without departing from the spirit of the invention hereinafter more fully set forth and specifically claimed.
At 10 we show a machine of any suitable character into which wateris to be delivered through a pipe 11 and from which the water may be drawn through an outlet pipe 12. 13 indicates a valve casing adapted to receive cold water through a pipe 14 and hot water through a pipe 15, said casing having means within it to control the supply of water with respect to its being hot or cold, and deliver the same into and through the inlet pipe 11.
' The valve casing 13, shown best in Fig. 2, is of peculiar construction and includes a statlonary cylindrical shell 16 having two circular series of inlet ports 17 surrounding the same. Said series are spaced from each other on opposite sides of the plane coinciding with the axes of the hot and cold water pipes 1-1 and 15. each of these pipes admitted into the cas- The water from ing is received upon the outer cylindrical surface of the shell 16 and is conveyed along the outer surface of the shell within an annular chamber 18 in communication with the set of ports 17 pertaining thereto; that is to say, the water from the pipe 15 flows through the shell 16 in one of the series of p01'ts17, and the cold water flows through its shell. 18 to and through the other series of ports 17 into the interior of the shell 16.
At 19 we show a movable or slidable valve adapted to be reciprocated within the shell 16 by any suitable means and from any desired location. Said movable valve 19 is provided with two sets of ports 20 and 21 adapted to register respectively with the hot and cold inlet ports 17 of the shell 16 when the valve 19 is open. Figs. 2 and 4;
show'the valve 19 in closed position and with the cylindrical surface of the valve closing theports 17. The valve has a rim 22 which, in closed position, abuts against the righthand end of the shell '16. As a 'suit'able'means formanipulating the valve 19, automatically, we connect to it a neck or shank 23 carrying a piston 24: operating within the cylinder 25 at the left hand end of the main valve casing 13. The cylinder 25 is provided with ports 25 and 25 lead ing to the opposite ends thereof from a pilot valve chamber 26 in communication through a port 27 with the cold water chamber 18. 28 indicates a pilot valve slidable in said chamber 26 and adapted to control said ports 25 and 25". In the neutral position of the pilot valve, as shown in Fig. 2, both of said ports are closed.
At 29 we show a float disposed in a chamber 30 in communication with the water space of the washing machine, the position I of the float being determined by-the amount of water in the machine. 'A link 3l'isconnected by means of an adjustable head 32 to a yoke 33, the adjustment being effected by meansof a thumb nut 34. Said 'yokeis secured to a shaft 35 journaled in a bushing 36 at the'front side of the .wall of the'cylinder 25, and the inner end of said shaft is bent upwardly at 35 and formed with a yoke 37 engagingthe middle portion of said valve 28. The yoke 33 in which the link '31 is adjustably connected extends laterally from the vertical plane of the'shaft 35, and when said link is connected to the right hand end of the yoke, as shown in Fig. 7 the fall of Water level within the machine 10 will cause a corresponding drop of the float 29 and a movement of the yoke 33 and shaft 35 in a clockwise direction whereby the yoke 37 will move the pilot valve 28 toward the right uncovering the port Water entering the chamber 26 from the cold water supply and passing through a port 28 of said pilot valve will enter the cylinder 25 and force the piston 24 and the valve 19 toward the right, bringing theports 20 and 21 into registry with the inlet ports 1'? and opening a series of outlet ports 38 into communication with the chamber 39 within the outermost shell of the main valve casing which is in communication with the pipe 11 leading to the washing machine. It will thus appear that the desired level of water in the machine may be automatically maintained by means of the float connection with the pilot valve 28. When the float 29 is lifted by the full supply of water within the machine, the valve 28 is returned to the position shown in Fig. 7, at which time water pressure enters the cylinder 25 through the port 25 forcing the piston toward the left and shutting. o the water vby closing the ports 38. Upon setting thepilot valve 28 to its neutral position, as shown in Figs. 1 and 2, the valve 19 will remain closed.
Any suitable meansmay be used to cooperate with the movable valve 19 to determine the kind or character of water or the relative quantities of hotjand coldwater to be delivered to and mixed within the valve casing. As a convenient and practical means for accomplishing this purpose, we provide a hollow cylindrical cut-off 39 fitted slidably within the shell of the valve 19 and operating between one series of inlet ports 20 and j the "other 21. The cylindrical cutoff 39 I may entirely close either of said sets of ports the open ports are made effective in an or may be adjusted so as to lie at any point between them, either leaving both sets open or leaving one openland the other partially closed, it being understood, ofcourse, that case only when they are in registry with the it a stem 40 through a spider 41 at the inner end,,and sald stem is connected to a hand Patent lever 42 adjustable along a segment 43 whereby the position of the cut-off is determined according to the temperature of the water desired. When adjusted to mid position, as shown in Fig. 7 both hot and vcold water will be received when the valve 19 is open and delivered to the machine. Ifcold water only is desired, said cut-olf 39" will. be adjusted toward the right so as to close the ports 20 and 17 in communication with the hot water supply pipe 15.- If 1 hot water only is desired, the lever 42 will be adjusted toward the left, whereby the ports21 and 17 closed. As shown in dotted lines in Fig. 4, the cut-oif'is located so as to onlypartially close the cold water supply ports, and hence it will be understood that by providing a The cut-off and its pertaining to the cold water supply will be justments orautomatic operation hereinbefore described. I
At 44 weshow a drain pipe leading from the cylinder of the pilot valve and controlled by a pet cook 45. .Among the objects of this drain is to provide for relieving the valve mechanism of'water, which, when the machine is cold, m1ght freeze therein; and also to allow any leakage to pass freely from the valve into the main dischargepipe.
Having thus described our invention, we clalm as new and. deslre to secure byLetters 1. in afdeviceof the character set forth, the combination of a main casing having means to supply thereto different characters of fluid,- a cylindrical shell within the casing, said shell having two series of cir'cum ferentially' arranged inlet ports communicating with the several supply means, said sup- ;ply means including circumferential, chamfbers extending around and inv communicai tion with the respective ports, a cylindrical lvalve slidable withinthe shell and having two sets of ports adapted to register with the aforesaid ports, a cut-off slidablewithinthe valve and adapted to close either-series of ports aforesaid, and meansto reciprocate said'valve independently of the operation of the cut-01f.
