JOHN R. EBERMAN, OF SANDY LAKE, PENNSYLVANIA.

INJECTOR.

SPECIFICATION forming part of Letters Patent No. 225,749, dated March 23, 1880.

Application filed September 5, 1879.

To all whom it may concern:

Be it known that I, J OHN R. EBERMAN, of Sandy Lake, in the county of Mercer and State of Pennsylvania, have invented certain new and useful Improvements in Injectors; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referencebein g had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to an improved device for raising water and feeding it into steamboilers or other receptacles, the object being to raise water from a well or other supply and force it into a boiler or other desired place of discharge with the least expenditure of steam and in the most positive and certain manner.

To this end my invention consists, first, in providing an injector with a valve which communicates with the steam-supply and is adapted in itself to completely control the working of said injector, the latter being started, governed, and stopped solely by the operation of said valve.

The invention consists, secondly, in providing an injector with a valve communicating with the steam-supply and having ports which are adapted by the rotation of said valve to register with certain ports leading to the lifting and forcing conduits, the construction being such that steam is admitted to said conduits, and both the exhaust and overflow are opened and closed by said stop device. By this means I dispense with all throttle-valves and like moving parts, and render the opera tion of the device simple, and its execution positive and certain.

The invention further consists of the several details of construction which are hereinafter described and claimed.

In the drawings, Figure 1 is a view, in side perspective, of the injector. Fig. 2 is a longitudinal section taken through the lifting and forcing conduits of the injector. Fig.3 is a longitudinal section taken through the hollow plug-valve, showing its position when steam is admitted to the lifting-conduits and the water escaping through the overflow-passage. Fig.

4: is a longitudinal section, showing the valve in proper position for admitting steam to the lifting and forcing conduits, and the overflowpassages closed. Fig. 5 is adetached view of the valve. Figs. 6 and 7 represent views of other water supply. B is the steam-supply pipe, attached by any suitable device, and leading to the dome or other steam part of the boiler. G is the discharge-pipe, suitably con nected, and leading to the bottom or other water part of the boiler. discharge-pipe is a similar discharge-pipe, G, which may be closed with a solid cap, or to which a hose and nozzle may be attached, and through which the water may be forced in case of fire or for any purpose. hollow plug-valve by which the injector is started, stopped, and entirely operated and completely controlled. The two receiving or lifting conduits E are each provided with an interior screw-thread, which extends from their upper extremities to a point below the line on which the water-supply is admitted to said conduits, respectively, by branches a of said supply-pipe A.

In each of the conduits E is placed a plug,

F, provided with a central longitudinal opening, 1). These perforated tubes or plugs are screwed down in their respective conduits, so that they are just belowthe line on which the water is admitted to said conduits. the plugs F, in the conduits E, are placed, respectively, the plugs or tubes Gr. Each of the latter is provided with a longitudinal central opening, 0, located directly above and opposite the respective openings 1) in the plugs F, and

immediately above the line on which the water is admitted to said conduits.

The upper ends of the conduits are closed by screw-threaded plugs H. These receiving or lifting conduits below plugs F are formed in approaching curves, and meet or intersect a third or forcing conduit, L. This latter conduit extends from the bottom of the device upward to a point some distance above the, line on which it is intersected, and a steam IOO Opposite this boiler 65 D represents the 70 Above 85 In the lower end of the forcing-conduit L is secured a perforated plug or combining-tube, N, the upper end of this latter tube being at the intersecting point of the conduits E, and.

directly below the lower end of the steam-plug M. The lower end of the conduit L is closed by a screw-threaded plug or cap, P.

The hollow plug-valve D is made tapering from its top to its lower end, and is provided with a lever or handle, Q. It is seated in a longitudinal opening or concavity, B, formed in the side of the injector-body, and adapted to have the valve lit closely therein. Said valve is further provided with a longitudinal central opening, f, extending from its lower or smaller end to a point near its middle. Two ports, 9 and h, are formed in the side of the valve and communicate with said opensf- Above the partition 6, which constitutes the upper end of said lower tubular opening in the valve, is an upper tubular opening, 122. This latter opening extends from said partition upward to a point near the upper extremity of the valve. Three ports, a 0 p, are formed in the side of the valve, connected with this upper tubular opening. Leading from the seat or concavity R, in which the valve works, and near the top thereof, is a port, 1", which communicates with the lifting or receiving conduits E. This port is in the same transverse plane with port 0 of the hollow plug-valve. Below said port r is another port, 8, which leads from said seat It into the upper end of the forcing-conduit L. This latter port is in the same transverse plane with the port 1) in the hollow plug-valve. The port a in the valve is in the same transverse plane with the steamsupply pipe B. Below the port 8 is another conduit-port, t, which leads to the forcingconduit L, at the point of intersection of the latter with the conduits E. This latter port is in the same transverse plane of the injector that the port g of the valve is in. A fourth conduit-port, w, is formed below port It, and communicates with the forcing-conduit L at a point below the perforated plug or combiningtube N. This port to is in the same transverse plane with port h of the hollow plugvalve. The lower end of said valve remains open.

The several ports of the valve are so ar ranged and located that when the latter is placed in the proper position the steam-supply pipe B is closed and the injector is not in operation. To operate it said valve is rotated on its longitudinal axis so as to admit steam from said steam-pipe, through port 12 of the valve, into the upper tubular opening, m. Simultaneously with the above, the port 0 of the valve is broughtinto registering position with the conduit-port r, and thus steam is admitted to the lifting or receiving conduits F. As the steam passes through the perforated plugs G and F directly across and at right angles with the branches to of the water-supply A, a vacuum is thereby createdin the latter. Hence water is forced by the atmospheric pressure from the place of supply up and into the conduits E; thence the water exhausts through conduitports t and w, and through ports g and h of the valve.

The above-mentioned rotary movement of the valve having registered said ports t g, and also said ports to h, the water flows out at the lower end of the tubular opening f of the valve. As the said valve is further rotated, its port 1) is brought into registering position with conduit-port s, and steam is thereby admitted into the upper end of the forcingconduit L. This steam,passing through the steam-plug M in a jet, comes in contact with the water at the intersection of said conduits E, and forces the water with great power through the combining-plug N. This second rotation of the valve has also closed the exhaust-passage t g, and partially closed the overflow-passage. The valve being now rotated for the third time, this overflow-passage w It becomes entirely closed, While, the conduit-ports 0 p being in full registering position, respectively, with ports 1' s of the valve, the water is forced through the discharge-pipe G into the steam-boiler or other desired place of discharge, or the water is forced by pipe O through a hose and nozzle, in case of fire or for any purpose.

An injector constructed in accordance with the foregoing description possesses many advantages, among which are prominent the simplicity and certainty which characterize its operation. All throttles and valves are dispensed with; the hollow plug-valve constitutes the sole moving part by which the injector is started, stopped, and controlled.

Inasmuch as all the ports of the valve move together with the latter, there is necessarily a unison and harmony of operation as regards said ports. Hence all extra pressures and jars are obviated, and the current or continuous flow of the water is unobstructed.

The work of raising the water is so disposed between the two injectors that the latter will respectively accomplish their maximum am ount of work. The forcing-injector then takes the water and, assisted by the lifting-injectors, forces the same with ease and certainty into the boiler or other desired place of discharge; By placing a throttle in the s'teamsupply pipe near the boiler, to be used only in freezing weather, the throttle may be closed and the hollow plug-valve be removed from the injector. The latter will then drain perfectly dry, and thus obviate all danger from frost or freezing, whereby a constant source of annoyance and danger in injectors is obviated. Again, by attaching a hose to the discharge provided for such purpose the injector is adapted for use as an extinguisher in case of fire, or the water, at a high temperature, may thereby be forced or thrown into the tank or well to prevent freezing in winter.

The foregoing description and the accompanying drawings set forth the principle of my invention in one form of embodiment; but it will beunderstood that the same does not restrict my improvement, inasmuch as thelatter is a broad departure from the injectors previously used, and the doctrine of equivalents applies to its construction.

Instead of employing a hollow plug-valve for regulating the admission of steam to the injector, and also for governing the overflowports, I may use an oscillating rotary slide or hollow piston valve for accomplishing the same result, it being only necessary to arrange the ports in any construction or type of valve that they may be opened and closed in the order and in the manner hereinbeforedescribed.

In Fig. 6, I have represented the valve-seat as being flat, with the same number and arrangement of ports therein, as illustrated in the drawings hereinbefore described.

In Fig. 7, V is an oscillating valve, pivoted at o, a handle being secured to its pivotal shaft, by which the valve may be readily shifted to the right or left, as desired. Valve V is provided at its lower end with elongated ports V V When the upper end of the valve is shifted to the right it uncovers the steamport, admitting steam to the lifters, and also simultaneously shifts the oblong ports V V, to register and connect with the overflow-passage W, formed in the face of the valve-seat, thereby allowing the water to freely flowfroni the injector outwardly through such overflowports. After a current has been established the upper portion of the valve is shifted to the right a sufficient distance to admit steam through the lower steam-port in the valve-seat, which connects with the forcing-plug of the injector, and also the upper steam-port, and this movement of the valve serves to throw the lower portion of the valve a sufficient distance to the left to disconnect the oblong ports from the overflow-ports in the valve-seat, and thus cut off the overflow and cause the water to be forced through the forcing -plugs, and from thence into the boiler. Other construction and arrangement of parts may be devised for effecting the same result; and hence I would have it understood that I consider as coming within the scope of my invention an injector provided with a single valve for simultaneously opening and closing the steam and overflow ports thereof, regardless of the construction and arrangement of the valve.

Having fully described my inventiofl, what I claim as new, and desire to secure by Letters Patent, is-

1. In an injector, the combination, with lifting and forcing conduits and ports connecting said conduits with a valve-chamber, and an overflow-passage leading from the intersection of the lifting and forcing conduits to the valvechamber, of a single valve constructed to simultaneously admit steam to the lifting-conduits and open the overflow-passage to establish a current through the injector only, sub stantially as set forth.

2. In an injector, the combination, with lifting and forcing conduits and ports connecting said conduits with a valvechamber,and an overflow-passage leading from the intersection of the lifting and forcing conduits to the valvechamber, of a single valve constructed and adapted to admit steam to both lifting and forcing conduits, and close the discharge of water through both overflow-ports, substantially as set forth.

3. In an injector, the combination, with lifting and forcing conduits and ports communicating with a valve-chamber, of a plug-valve provided with ports adapted and arranged to register with ports to the lifting and forcing conduits, said' valve provided with an inner steam-passage which may be connected with or disconnected from the steam-supply, substantially as set forth.

4. In an injector, the combination, with liftin g and forcin g conduits and ports communicating with a valve-chamber, of a plug-valve provided with an inner steam-passage adapted to be connected with or disconnected from the steam supply, said plug-valve being provided with ports so arranged that steam may be conveyed to the lifting-conduit only, or may be conveyed to both the lifting and forcing conduits, substantially as set forth.

5. In an injector, the combination, with lifting and forcing conduits and ports communicating with a "alvechamber, and an overflowpassage leading from the intersection of the lifting and forcing conduits to the valve-chamber, of a hollow plug-valve provided'with ports for simultaneously admitting steam through the valve to the lifting and forcing conduits and allowing the overflow to escape through the valve, substantially as set forth.

6. In an injector, the combination, with lifting and forcing conduits having ports leading to a valve-chamber and an overflow-passage leading from the intersection of the lifting and forcing conduits to the valve-chamber, of a hollow plug valve provided with separate steam and overflow chambers, said chambers provided with ports which may connect or disconnect said chambers with the lifting and forcing conduits and overflow-passage, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 2d day of September, 1879.
