INJECTOR.

Application filed June 28,

T 0 all whom it may concern:

Be it known that I, JAMES M. GAILEY, a citizen of the United States, residing at Mo- Keesport, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Injectors, of which the following is a specification.

This invention relates to injectors.

There is a known injector with which I am familiar that is provided with what is termed an inlet valve. When an injector is in operation water is passing therethrough and there is always more or less sediment or dirt in such water. This foreign matter frequently clogs the valve and sometimes its closing spring so that the former will not seat. When such a condition as this ensues the injector becomes non-lifting and has to be taken apart and. the valve cleaned. By virtue of my invention I eliminate wholly this disadvantage. I provide an inlet valve and a spring for closing the same which requires only to be under rather light tension and, in addition to this, also provide means for bodily shifting the valve, by virtue of which the sediment, dirt, and the like which-adhere to the valve can be removed.

In the drawings accompanying and formin part of this specification I show in detail one form of embodiment of the invention which, to enable those skilled in the art to practice the same, will be set forth at length in the following description, while the novelty of the invention will be included in the claims succeeding said description.

Referring to said drawings: Figure 1 is a vertical section of an injector involving my invention. Fig. 2 is a similar view of the said inlet valve and certain adjacent cooperating devices; Fig. 3 is a transverse section of the parts shown in Fig. 2, both said Figs. 2 and 3 being upon an enlarged scale.

Like characters refer to like parts throughout the several figures of the drawings.

In Fig. 1 I have shown certain parts of an injector and with the same my improve ment. I will briefly allude to the old parts and will thereafter describe the improvement in detail and, for this purpose, reference may be had initially to Fig. 1. The various operative parts of the injector are housed within a casing such as 1. Said casing has a branch as 2 for the admission of steam, a water-supply branch as 8, a wastesupply branch as 4, and a branch as 5 through Specification of Letters Patent.

Y which the boiler (not shown) is supplied with its water. The steam-nozzle is denoted by 6 and is controlled by a valve as 7. In the casing 1 is a chamber as 8 which has communication with the water-supply branch 3. The parts hereinbefore described are I believe old, for which purpose they have been but briefly alluded to. Communication between the chamber or compartment 8 and the watersupply branch 3 is controlled by a valve as 9, said valve being in the present case of disk type and closing against a seat at the inner otherwise suitably fitted in the partition or wall 11. In addition to the valve 9 there is a second or cut-off valve 12 which I believe is common in this class of devices and which is substantially of cylindrical form. The stem of said valve 12 is denoted by 13 and it has attached suitably to its outer end an arm as 14 by which the valve 12 can be turned to control the supply of water to the injector. The inner end of the valve 12 fits against and turns upon the sleeve or collar 1.0 through which the stem 15 of the inlet valve 9 eX- tends, said stem 15 being guided by a spider as 16 in the sleeve or collar 10. The stem 15 as 17 bearing at its forward or inner end against the spider 16 and at its outer end against a shoulder or collar as 18 on said stem 15. The collar 18 may be adjustable to regulate the tension of the spring 17. This tension is comparatively light, although it is sufficient to normally hold the valve 9 against its seat at the forward or inner end of the sleeve 10.

The water valve stem 13 is hollow or tubular, and through said stem the rod 19 is shown as extending, a lever as 20 being represented as pivotally connected between its ends to the outer end of said rod 19. One end of the said lever is shown as pivotally connected to a link as 21 likewise jointed at its opposite end to the arm 14 which, it will be understood, is turned to effect the operation of the main or water-controlling valve 12. Owing to the connection between the two actuating devices 14 and 20 the latter will turn with the former so that the free end of the lever or arm 20 is always in position for operation by the individual using the main arm or lever 14. The rod 19 extends entirely through the tubular or hollow stem 13 and its inner end is shown as revolubly and loosely connected with the stem 15. I

end of the sleeve or collar 10 threaded or is shown as encircled by a coiled push-spring can obtain this result in the present case by the following construction: The inner end of said rod 19 is shown as having a hook as 22 inclosed by the main valve 12, one branch or 5 the bill-portion of the hook being forked as at 23. Said fork 23 straddles the stem 15 and is situated between the shoulder or collar 24 and the shoulder or collar 25. By virtue of this construction it will be apparent that the lever or arm 14 can be manipulated to effect the operation of the main or watercontrolling valve 12 without affecting the inlet valve 9. The inlet valve 9 is held normally closed by the spring 17. When said 15 inlet or auxiliary valve 9 is opened the spring 17 is put under additional compression so that, when the valve 9 is released from open ing pressure, the spring 17 can close the same against its seat on the sleeve 10. Should,

20 however, the valve 9 fail to seat or close from the causes hereinbefore mentioned, it can be thrust open by the operation of the lever 20 acting through the rod 19 and cooperating devices, so as to permit the water to dislodge any substances which may adhere to the valve or spring. I might explain that, when the rod 19 is thrust forward by swinging the L hand lever 20, the inner or bifurcated portion of the hook 22 acts against the collar or shoulder 25 to move the valve towards its open position, whereby the results set forth can be accomplished. When the difliculty has been removed the lever 20 is returned to its original or retracted position, after which the inlet or auxiliary valve 9 can follow its normal operation. As the means which effects the opening of said inlet or auxiliary valve is accessible exteriorly of the injector or casing, it is a very simple matter to correct any defect in the closing of said valve should the same exist.

What I claim is:

1. An injector having a main or watercontrolling valve provided with a tubular stem, an auxiliary valve, a rod extending through said tubular stem and turnably connected with said inlet or auxiliary valve, a "hand-operable member connected with said stem for turning the same, a hand-operable member connected with said rod for moving the same in an endwise direction to cause the operation of said auxiliary or inlet valve, and linkage means jointed to the two hand-operable members for causing them to turn to gether.

2. In an injector, a casing provided with an internal partition separating the same Iiinto chambers, a main or water-controlling valve in one of said chambers, an auxiliary or inlet valve in the other chamber, means for positively closing said auxiliary or inlet valve toward said partition, and means for moving the valve towardand from the partition independently of the closing means therefor.

3. In an injector, a casing having an internal partition dividing the same into two chambers, a main or water-controlling valve in one chamber, an auxiliary or inlet valve in the other chamber, a spring acting against said auxiliary or inlet valve to close the same toward said partition, means involving a hand-operable member for operating said auxiliary or inlet valve independently of said spring, said hand-operable member being accessible exteriorly of the casing, and means for operating the main or water-controlling valve.

4. An injector having a main or watercontrolling valve provided with a tubular stem, an auxiliary or inlet valve, a spring for closing said auxiliary or inlet valve, a rod extending through said stem and having a hook provided with a bifurcation, the auxiliary valve having a stem straddled by said bifurcation and also having shoulders between which the bifurcation is located, and a lever connected with said rod for moving the same in an endwise direction to cause the hook to act on one of said shoulders to open the inlet or auxiliary valve.

5. An injector having a main or watercontrolling valve provided with a rotary tubularstem, an auxiliary or inlet valve, an endwise movable rod extending through said stem and connected with said auxiliary valve for operating the same, a lever connected with said rod to move the same in an endwise direction, a lever fastened to said stem for turning the same, and a link jointed to the respective levers for causing them to turn together.

6. An injector having a main or watercontrolling valve provided with a tubular stem, means for turning the stem to thereby operate said main or water-controlling valve,

an auxiliary or inlet valve, an endwise movable rod extending through said stem, the rod having a bifurcation, and the auxiliary or inlet valve having a stem straddled by said bifurc ation and also having collars against which the bifurcation is adapted to alternately bear, and means for operating said rod in an endwise direction.

7. An injector having a main or water controlling valve provided with a rotary tubular stem, an auxiliary or inlet valve, an endwise movable rod extending through said stem and connected with said auxiliary valve, a lever connected with said rod for operating the same, a lever on said stem to turn the same, and an operative connection between the two levers.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
