UNITED STATES Application filc-d duly 14,

The operating mechanism of the present invention finds its preferred embodiment in association with a steam jet pump, but it is to be understood that the mechanism may have a wide range of utility in the arts and is applicable to any float controlled quick acting valve.- I

An object of the invention is to provide an opera-tor for steam jet pumps which will in automatically limit the; rise of watle-r in the receiver by opening the ejector valve whenever the water reaches a predetermined level. The pressure medium controlled by this valve for operating the ejectormay be either vsteamor water in accordance with the particular type of ejector used, and in the case-of. steam, the wire drawing action is entirely eliminated since the valve is always wide open or tightly shut.

A further object of the invention is to provide an automatic operator which may be applied with facility to any conventional steam jet pump installation. 3

Further objects of theinvention are to provide an operating mechanism of simple practical construction which will be rugged, durable and eflicient in use and which may be manufactured, applied and operated with comparative economy.

The device is intended as a substitute for an automatic steam oreleotrio pump and is of such a nature that it maybe applied at a considerably lower cost than the original cost of such an automatic pump;

WVith the above fact and other objects in view the invention consists in certain novel features of construction and the functions and arrangements of parts, as will be more fully hereinafter described and set forth in the claim.

The invention may be better understood from the following description in connection with the' accompanying drawings. wherein:

Figure 1 is a View partly in side elevation and partly in section showing my improved operating mechanism applied to a conventional type of steam jet pump;

Figure 2 is a top plan View of Figure 1; and

Figure 3 is a sectional detail on the staggered line 33 of Figure 1.

In the drawings I have used reference character 10 to designate a water reservoir or receiver. A conventional type'of ejector 1,545,639 A 0 FICE WILLIAM Jenn ANDERSON, or BROOKLYN, new YORK.

11 is connected by pipe12 withthe'bo'ttom of the rece ver, the pipe being apertured at V 13'to'permit the free flow of water into the lower end of the pipe when the ejector is operated.

The fluid for operating the ejector, pref erablysteam, is supplied througha pipe acting globe valve 15 such for instance as an ordinary Jenkins valve. Th1s;valve' 1s normally' spring pressed to closed P OSI'GI'OIIIb ya line 1 1 inwhich thereis mounted a quick coil expansion spring 16 andcarries" an op per and lower stop pins 24 and 25; The upper end 26 of the float rod constitutes a pusher for engaging a tilting liquid container 27 supported above the pipe line 14 on an arm 28. The lower end of the arm 28 is fulcrumed at 29 on a collar30 encircling the pipe line 14. With the float 23 in the position of Figure 1 the tilting or balancing tank 271$ supported by a yoke rest 31 secured tothe casting 18.

A U-shaped yoke, consisting of a pair of levers 32 and a cross-piece 33 is fulcrumed at 34 on a pair of rigid supporting arms 35 carried by a pipe line 14. The arms .32 are fulcrumed intermediate their ends and crosspiece 33 normally supports an actuating lever 36 for'the valve stem 17 in elevated position, out of contact with the stem.-

The free ends of the arms 32 are engaged by hooks 37 mounted on the float rod 22, the weight of the float rodacting through the hooks 37 to retainthe yoke 32, 33 in'the position of Figure 1.

The operation of the device is substantially as follows:

When the water level rises in the receiver 10 the float 23 will ride freely up the float stem until it engages the upper stop 24, at. which time the float rod and its associated mechanism will move with the float. Upward movement of the float rod causes its pushing end 26 to pass through open:

, 16 will restore thequick-acting valve to V ing in the casting 18 and to tilt the balancing tank 27. The liquid mercury or other contents of the tank 27 will run toward the V to the ejector 11 and the water from the receiver will be withdrawn by the ejector and delivered to any suitable location.

i As the water level lowers the float 23 will move toward the bottomof the receiver and engaging the lower stop 25 will add suliicient weight tothe floating rod to reset the balancin tank. This resettin is effected throughthe medium of the levers-32, which are pulled down by thehooks 37, consequently, moving lever 36 upwardly by the crosspiece 33 and shifting the tank 27 back to its original position. As the tank 27 is restored to its original position the spring closed position, cutting off the supply of steam to the ejector.

Obviously, various changes and alterations might be made in the general form and arrangement of the parts described without departing from the invention, and hence I do not wish to limit myself to the details set forth, and shall consider myself at liberty to make all changes which fairly fall within the spirit and scope of the appended claim.

What I claim is:

A quick acting valve mechanism normally spring held in. closed position, a tank, a float in the tank, and means under control of the float for opening the valve, said means including a float rod actuated by the float, a pivoted balancing device adapted'to be actuated by the float rod, and a valve operating lever shifted by the balancing device, a pair of pivoted levers, means carried by the levers for lifting the valve lever, hooks in the free ends of the first mentioned levers, whereby the balancing device is reset by the float mechanism.
