IMPROVEMENT iN INJECTOR AND EJECTR VALVE-RODS.
Specification forming part of Letters Patent No. 128,232, dated June 25, 1872.
SPECIFICATION.
pipe is not violently impingcd on and driven I back.
My improvements consist mainly in so forming a rod in connection with an ordinary angle-valve, as will be hereinafter more fully explained, as to allow both to be operated at oney and the same time by the same movement, the rod being arranged to permit a gentle and even flow of steam through one end, so that when the steam comes in Contact with the water entering through its proper channel, the latter is not -driven by the sudden pressure of the steam against it, and the operation of the valve, &c., is not otherwise interfered with.
In the drawing, a a represent a rod formed at one end with a longitudinal aperture, b, and a transverse aperture, c, andv attached at its other end to an ordinary steam-valve, d, which, together with the rod a a; is operated by a wheel or other suitable device connected with a stem, e, of the valve d. The rod a a plays longitudinally within the bore of the steamnozzle f, and impinges against, at one end, the inner periphery of the mouth of the nozzle f. Around the outside of the mouth of the nozzle fa passage, g g, is formed for the admission Of water which is introduced through the pipe h. A passage, k k, tapering toward the end of the rod a a, is formed by the bore Of the nozzle f, around the rod a a, for the entrance ofthe steani,whichisintroducedthrough the pipe l. Y v
By the above arrangement, as shown by the firm lines of the drawing, my invention is used as an ejector 5 but when the above is combined with, the overow valve-pipe m, and boiler valve-pipe n, already patented by me, it is used as an injector..
Reference being had to the drawing, it will readily be seen that by operating the Wheel, or other device connected with the stem e of the valve d, to which the rodal a is attached,
both are actuated by one and the same movement, which admits the steam through the pipe liuto the passage 7c lc, and thence through the transverse aperture c and longitudinal aperture b, where it is contracted in volume, and gently comes in contact with the water, which is introduced through the pipe h, and ilows through the narrow passage g g, Out of the mouth of the combination pipe p; or acting in connection with the overiOW valvepipe m, and the boiler valve-pipe u, shown by the dotted lines, the above arrangement Of devices acts as an injector.
Having thus fully described my improvel ments, what I claim as myinvention, and desire to have secured to me by Letters Patent, 1s-
1. A steam injector or ejector, having a rod, a a, provided with a longitudinal aperture, b, and a transverse aperture, c, at one end, and attached at the other end to a steam-valve, d, the said rod a a and steam-valve d being operated by one and the same movement, substantially as specified.
2. The longitudinal aperture b and transverse aperture `c formed in the end of the rod a a attached to the steam-valve d, substantially as specitied.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
WM. B. MACK.
