LOVREN E. HOGUE, OF GREENVILLE, MERCER COUNTY, PENNSYLVANIA.
INJECTOR FOR STEAM-BOILERS.
SPECIFICATION forming part of Letters Patent No. 408,714, dated August'l, 1889.
Application led March 15, 1889. Serial No. 303,430. (Modell To all whom, t may concern:
Be it known that I, LOVREN E. IIOGUE, a citizen of the United States, residing at Greenville, in the county of Mercer and State of Pennsylvania, have invented certain new and useful Improvements in Injectors for Steam- Boilers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this speciiication, and to the letters and figures of reference marked thereon. Y
This invention relates to certain new and useful improvements in injectors, and more .particularly to that class of injectors having two barrels,a lifting-barrel and a forcingbarrel, the lifting-barrel proper being the same as is common to all injectors and the working or forcing barrel, having the forcingtubes in it, being also a lifting-barrel before the water arrives; but after the water arrives it is turned into a forcing-barrel by putting on the boiler-pressure, as will be more particularly hereinafter set forth.
The invention consists in the peculiar combinations and the novel construction, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawing, and then particularly pointed out in the appended claims.
Y The invention is clearly illustrated in the accompanying drawing, which is a longitudinal central section through my ilnproved inj ector.
Referring to the said drawing by letter, A designates the shell, having its body divided into two compartments.
B is the lifting-barrel, and C -the steamchamber for the lifting-tubes, which communicates with both barrels by the inclined tube D. This chamber is left open at all times, and is externally screw-threaded, as shown, to provide for 'its attachment to the steam-space of the boiler.
E is the water-inlet, also externally screwthreaded to provide for its ready attachment.
F is a hollow tube or chamber connecting the two barrels B and G, and also communicates with the overflow-opening a.
In the outer end of the barrel B, at itsjunctionwith the tube D, is the nozzle b, which is the steam-forcing tube proper, which always remains open, and while water is beinglifted into the device is an V`auxiliary lifter by the peculiar construction of the seat c in the forcing-barrel.
H and I are the lifting-tubes in the barrel G. The nozzle o and the valve-seat c form auxiliary lifting-tubes in the barrel B.
d is a coupling for attachment to the boiler, and wit-hin this is the valve J, which, when forced in, as shown, iinds a seat at its inner end against the valve-seat c.
eis a seat for the valve on the forcing-tube or' valve J, said valve being designated by the letterf and receives the boiler-pressure when thrown up into position.
In practice there should be a petcock (not here shown) attached to the feed-pipe leading into theboiler between the injector and the check, which, when opened, allows the valve J to fall back by relieving boiler-pressure, allowing it to remain there while water is being lifted.
The manner in which my double-lifting injector is operated is as follows: The chamber C and tube D being put in communicationwith the steam-space of the boiler, the opening in coupling d with the water-space of the boiler, and the opening E with the source of Water-supply, and steam being admitted into the chambers C and that in the tube D, the steam passes through the tubes I-I and I into the chamber F, and at the same time it passes through the steam-chamber D, lifting and forcing the nozzle b, and out at the overflow a, thus constituting a double-lifting injector. Vhen the water arrives at the overiiow, the petcock on the pipe leading into the boiler should be closed when the boiler-pressure shoves the valve J up against its seats c and e. Lifting-jets are made by a small steam-j et being passed through a larger opening in a tube beyond. The tube I is so constructed that air is caught by the steam in the top of the tapered tube and forced in the bottom,so
that' when water arrives it is used as apartial IOO causing a suction on the tube I. Yhen the valve J is in its farthest position from that in which it is shown, the device is simply a direct and perfect double lifter.
Vhat I claim as new is- In an injector, the coinbination,witl1 the shell formed with two barrels, of theinclined tube D, the chamber F, connecting the two barrels, and thev nozzle Z) and valve J upon opposite sides of the overiow, substantially as shown and described,
2. In an injector, the combination, with the shell formed with two barrels and the inclined tube D, arranged as shown, of the forcingtubes H and I in one of said barrels, the nozzle l) in the other, and the valve J in the barrel with said nozzle upon the opposite side of the overflow, substantially as shown and described.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses. v
