SPECIFICATION forming part of Letters Patent No. 299,230, dated May 27, 1884.
Application filed November 12), 1883.
To aZZwQ/om it may concern,.-
Be it known th at I, FRANKLIN W. KREMER, a citizen ofthe United States,residing at fadsworth, inthe county of Medina and State of Ohio, have invented` certain new and useful Improvements in Injectors, of which the following is a full, clear, and exact description.
This invention is in the nature of improvements in the class mof injectors represented in my United States Letters Patent No. 282,092, dated July 3l, 1883; and the improvements consist in the arrangement and operation of certain valves or cocks for controlling Vthe steam and water, and also in the combination therewith of the overflow, as I shall now proceed to particularly describe and claim.
In the accompanying drawing one form of my invention is illustrated in central longitudinal section, the steam-valves being in elevation, and the machine being in position for starting.
The several sections a b c of the injector are preferably connected by ground or ground and packed joints, or rabbeting, as in the patent referred to. c is the steam-inlet, and (Z the steam-chamber, which latter opens into the suction-chamber ethrough a lifting jet-tube, f, in an otherwise solid diaphragm dividing the section a into the said steam-ch amber and suction-cham! ber. This jet-tube is opened and closed by a valve, g, seating on it, and having a screwthreaded stem, g, running in the gland or bonnet g2, and operated by a hand-wheel or handle, g3. y
h is the combining-tube arranged in the suction-chamber, and having its receiving end centered just below the jet-tube, witha space between them, the said combining-tube being supported by its base h', arranged between or in the joint of the sections a b. The section b contains the supply-chamberz`, which is divided by a diaphragm, i, having in it a passage, i2. This diaphragm has also a vertical tubular cavity, j, meeting a horizontal passage, j',
leading outside the section, and this passage has connected with it a cock, 7c, in which the valve k is seated to control the inlet of steam from the pipe 7a2, to' convert the injector from a lifting to a non-lifting or forcing machine. The valve lo has a suitable screw-threaded stem running in a bonnet, and having an op- (Model.)
erating wheel or handle, substantially as shown. The pipek3 is connected with the cock by a slip-joint, as in the patent referred to. The tubular cavity j terminates in Jthe forcing jet-tubcjz, and I shall hereinafter refer to the centered below the force-combining tube Z.
Connected with the section c is a cock, o, havingV the valve-seat p, an outlet, p, and a bonnet, p2. The valve-seat p is occupied by a valve, q, having a tubular stem, r, by which it is connected with the stem-s.' This stem s has a nib, s', on which the tubular stem of the valve slips, and a screw-threaded portion, s2, by which it is run in and out of the bonnet p2, and ka hand-wheel or handle, s3, by which it is operated. The'valve q has a movement independent of the stem s, is substantiallya checkvalve, and constitutes the overflow or exhaust controller.
Having thus described the construction and Varrangement of my improvements, I will now proceed to set forth the operation. In the drawing the parts are in position for starting, the valve opening the lifting jetetube f for the admission of steam through pipe cinto the suction-chamber, and the valvestem being partly withdrawn from the valve q, leaving said valve, however, seated on the seat p. The cock 7c is closed. Now, `the steam escaping through the lifting-jet f into the chamber c creates a vacuum thereiinwhereby an iniow of the water through pipe t is caused, fillingl the chamber c, and then driven by the steam down through the combining-tube 71., passage t2, and holes Z into the overflow-chamber. The pressure coming thence against the valve q, it will slip back upon the stem-nib s and open the valve to permit overflow. When the water escapes from the cock 0, the valve k is IOO opened, letting steam into the supply-chamber t' through the passage 7" and jet-tube jg, where its pressure acts to drive the water through the combining-tube Z, whence it escapes initially into the exhaust; but the column or jet quickly attains sufficient velocity to force itself through the delivery-tube n tov the boiler. Now, if the water-supplyis not in excess of the steam-pressure, water will also be drawn in between the tubes Z n, and from the receiving or supply chamber fZ through the ports or holes Z, and the valve q will, by the consequent suction in the exhaust-chamber, be automatically seated. On the other hand, if the valve q be positively seated by its stem s, and the water-supply be in excess of the steam-pressure, and the steam be inadequate to carry the volume of water to the boiler, a portion of the waterwill be discharged between the tubes Z u and returned through ports Z to the supply-chamber. Thus it will be seen that the ported combining-tube e. Z becomes an equalizer and renders the im- Vpairment of the jet yby varying steam-pressure eqlualizer, completely obviating the use of one.
. On locomotives it is desirable to heat the water in the tanks in cold weather to prevent its freezing, and where the exhaust-valve cannot be closed, as is usually the case, this cannot be accomplished through the medium of the injector; but with my construction of exhaust the heating` of this water can bereadily done by turning down the stem s till the valve q is seated, and opening the steam-valve lc', when the steam will be blown back and heat the water.
Whatl claim isl. In an injector, the steam-chamber d, the valve g therein, the suction-chamber e, with which the steam chamber communicates through the lifting jet-tube f, under control of thesaid valve, the combining-tube 7L, aligned with the said lifting jet-tube, the overflowchamber m, the overiiow-cock o' therein, provided with the valve q, having automatic play through the lifting jet-tube f, under control of the said valve, the combining-tube h, aligned with the said lifting jet-tube, the forcing jettube j2 in the supply-chamber, and communieating with the steam-supply, withan interposed valve, k', the combining-tube Z, having ports Zin its base or flange to open independent communication between the suction and overliow or exhaust chambers, and the overflow-valve q, having an automatic and also a positive operation, all combined and arranged to operate substantialljv as shown and described. s
3. In an injector, the steam-chamber d, the valve g therein, the suction-chamber e, with which the steam chamber communicates through the lifting jet-tube f, under control of the said valve, the combining-tube h, aligned with the said lifting jet-tube, the forcing jettube jz in the supply-chamber, and communieating with the steam-supply, with an interposed valve, k, the combining-tube Z, having ports Z in its base or iiange to open independent communication between the suction and overiiow or exhaust chambers, the dischargetube n in the suction or exhaust chamber m,
