EDVIN J. YOUNG, OF VVADSVORTH, OHIO, ASSIGNOR TO THE OHIO INJEOTOR COMPANY, OF SAME PLACE.
INJECTOR.
SPECIFICATION forming part of Letters Patent No. 579,212, dated March 23, 189'?. Application filed July l1. 1896. Serial No. 598.878. (Model.)
T0 all whom t may concern.-
Beit known that I, ED WIN J. YOUNG, a citizen of the United States, residing at Vadsworth, in the county of Medina and State of Ohio, have invented a certain new and useful Improvement in Injectors, of which the following is a full, clear, and exact description.
The obj ect of this invention is to provide in one structure the three valves which are used for the inlet of the steam to an injector, to the lifting-tube, andto the forcing-tube, and to operate the said three valves conjointly or successively by a single operating device.
In the selected illustration of my invention I have shownV a double-tube injector, one of the tubes being the injector proper and the other tube being the ejector or lifter, to raise the water from a well orother source of supply to the injector, whence it is forced to the boiler. The injector comprises a steam inlet and chamber, a steam-nozzle and forcingtube, an overflow, and a boiler connection, which may be substantially as usual, excepting that a chamber is interposed between thev overflow and ejector and contains an automatic valve of this invention, and between the inlet and the steam-nozzle is interposed the triple valve of this invention, one portion of the valve serving to control the admission of steam to the injector and ejector, another portion of the valve cooperating with the firstnamed portion to control the admission of steam to the steam-nozzle and forcing-tube, and the third portion of the valve serving to cut off the supply of steam from the ejector, this triple valve having a common moving device, all as I will proceed nowinore particularly to set forth and finally claim.
In the accompanying drawings, illustrating my invention, in theseveral iigures of which like parts are similarly designated, Figure l is a longitudinal section of the complete apparatus with the parts shown as closed. Fig. 2 is a longitudinal section of a portion of the injector with the valves in position to admit steam to the ejector. Fig. 3 is a longitudinal section of a portion ofthe injector with the valves open, to admit steam both to the ejector and to the injector and its steam-nozzle aud forcing-tube. Fig. Il is a longitudinal section showing the triple valve in position to cut off the steam entirely from the ejector. Fig. 5 is a sectional elevation of the casing.
The casing a of the injector may be made in any usual manner and be supplied with a steam-inlet nipple a, an overow a2, and a boiler connection c3, and also with a steamnozzle a4 and a forcing-tube d5, all substantially as usual, excepting that the forcingtube is provided with spilling-ports as. The overflow is provided with a cap o, which also serves as a guide for the stem of the overflowvalve o.
c is a tube supplied with a nipple c" for connection with a water-supply, and the tube c contains the steam-nozzle c2 and the liftingtube c3, access to which is had by means of the removable cap c4, which cap also serves to close the steam-chamber c5. Vithin theinjector-t ube is the steam-chamber d, which is closed by the cap d. A second steam-chamber e is provided in the injector-tube, and the said chambers d and c are separated one from the other by means of the valve-seat f and the triple valve hereinafter described. A port g connects the steam-chamber e of the injector and the steam-chamber c5 of the ejector, and the said 'ejector is further connected with the injector by means of a duct 7L, which opens from the ejector into a chamber h in t-he injector adjacent to the overfiow and containing the automatic valve o'. This valve o is arranged immediately between said chamber and the overflow and controls communication between the ejector, chamber, and overiiow, and thus renders-the do uble-tube injector automatic in its action.
The triple valve comprises a tube c', having the valve portion j, which cooperates with the valve-seat f, and beyond the valve j the said tubular portion vl is provided with the ports or openings 7c. The portion c' is provided also with the valve-face l, which cooperates with the inlet g of the port g, the said valve-face Z traveling upon guides Z in the injector-tube ct. The farther end of the tubular portion il is partly closed by an annulus or liange fm. Within the tubular portion c' is arranged the independently-1novable valve n, which has a pointed end projecting beyond the tubular portion 'L' and adapted to cooperate with the steam-nozzle a4 as a valve- IOO seat, the said valve n having the shoulder n back of its projecting portion to cooperate with the annulus or iiange fm.
o is a valve-stem threaded, as shown, to cooperate with a complemental thread in the cap d and secured steam-tight in said cap by any suitable gland p, the said stem o having an operating-handle q outside of the in jectortube. This stem o has a head r, which is fitted to a cavity in the tubular portion t', and is secured therein with a capacity, if desired, of rotation by means of a nut s.
The tubular portion with its two valves j and Z, and the valve 'a constitute what I have herein designated a triple valve, and its functions, as already indicated and as will presently more fully appear, are to admit steam to the ejector alone and also and simultaneously to the ejector and the injector and to cut off steam from the ejector.
The operation is as follows: When the triple valve has been moved by the rotation of the spindle o sufficiently to clear the valve j from its seat f, steam will be admitted into the steam-chamber c and will pass into the port g and into the ejector, and at the same time the steam within the valve portion z' will serve to hold the valve n to its seat, and thus exclude steam from the steam-nozzle a4 and consequently the forcing-tube a5. As soon as the flow of water is established and appears at the overiow by lifting the valve b' a further movement is imparted to the triple valve by the rotationof the stem o until the annulus or flange m engages the shoulder a of the valve a and forces said valve from its seat in the steam-nozzle a4. Steam then will be admitted simultaneously to the injector and the ejector, and the water will be forced into the boiler. The triple valve then is given a further movement in the same direction until the valve Z is moved partly or wholly over the port g, thereby still admitting steam to the injector, but cutting off part or all ofthe steam from the ejector and consequently reducing the delivery of Water from the ejector to the quantity the forcer can deliver to the boiler, or, if desired, to a much smaller quantity, thereby grading the injector to its least capacity. Moreover, when water is supplied from city mains or other sources under pressure the valve Z may be used to cut oft all the steam from the ejector.
Thus it will be seen that the three valves are operated and controlled by a single device-namely, the stem 0 and its handle.
It is to be observed that my apparatus is perfectly automatic in action, as much so as any single-tube automatic injector.
If for any reason the jet should be momentarily broken after the injector is once started, the forcer will exhaust steam out through the overow until the ejector again lifts Water, at which time the forcer takes it and again establishes the jet to the boiler without any movement of the steam-valve by the operator.
It is to be observed, further, that there is nothing between the ejector and the overflow, excepting the automatic valve t', and that the water must pass the forcer on its way to the overflow-valve through chamber h'.
My apparatus is what may be designated a self-contained injector, requiring no valves in the steam and suction pipes, and is wholly controlled by the one operating device.' It will work on an eXtreme lift, or by cutting off the steam to the ejector it will work as a nonlifting injector and will work automatically under all conditions.
Vhat I claim isl. A triple valve for double-tube injectors, comprising a main steam-valve for controlling the admission of steam to both tubes, and a separate steam-valve under the main valve and operating automatically and independently of the main valve under steam-pressure and also conjointly and positively with the main valve, for controlling the admission of steam to the forcer, substantially as described.
