FRANKLIN W`. KREMER, OF VADSVORTH, OHIO, ASSIGNOR TO THE GAR- FIELD INJECTOR COMPANY, OF SAME PLACE.
AUTOMATIC LOCOMOTlVE-INJECTOR.
SPECIFICATION forming part of Letters Patent No. 374,975, dated December 20, 1887.
Application filed A1\rll15,1887. Serial Naim-1,944. (Model.)
To aZZ whom t may concern:
Be it known that I, FRANKLIN W'. KREMER, a citizen of the United States, residing at Vadsworth, in the county of Medina and State of Ohio, have invented certain new and useful Improvements in Automatic Locomotive-Injectors, of which the following is a full, clear, and exact description.
This invention relates to that class of devices for supplying steam-boilers with water represented in the United States Letters Patent No. 335,227, granted to meand dated February 2, 1586; and one special object of the presentinvention is to provide an injector of such a character as to be capable of lifting the water directly after being used as a heater, or when the suction or supply pipe becomes heated to such a temperature as to render it impossible to create a vacuum.
Other objects of the invention are to perfect the construction of certain details of the apparatus.
The invention consists in an injector construeted and operating in the manner substautiall y as hereinafter particularly set forth and claimed.
In the accompanying drawings, in the several figures of which like parts are similarly designated, Figure 1 is a perspective view of sufficient of a locomotive-engine and its tender to illustrate the application of my injector. Fig. 2 is a vertical longitudinal section of the injector, and Fig. 3 is a sectional elevation of a detail.
It is to be understood that an injector to meet the requirements of a locomotive must be so constructed that it can be used to heat the water in the tender or tank in cold Weather, in addition to its primary function of supplying water to the boiler. In the ordinary locomotive-injector it frequently occurs that after the instrument has been employed as a heater it becomes necessary to allow the instrument to cool before a vacuum can be producedto lift t-he water and the instrument restarted, delays thus ensuing which frequently are serions. In the present invention the difficulties just mentioned are entirely obviated, and the machine can be started instantly, regardnecting the injector with the tender or tank,
is designated D, while E designates the overflow. The controlling-valve is designated F, the steam-valve G, and the combined overfiow and frost valve or plug is designatcdtH. I also prefer to use a supplemental check-valve, I, in conjunction with the cheek-valve a.
rIhe valve G has certain details of construction, which Will be hereinafter more partielllarly set forth, but for the purpose of fully explaining the first part of my invention, I will now proceed to describe the operation of the injector constructed and arranged substantiall y as just set forth.
To operate the injector as a heater the val ve H is screwed down so as to close the overflow. The spindle b of this valve is provided with a screw-thread, c, of large pitch, so as to render said spindle quick-acting. Steam is now admitted by opening the valve G, and passes thence through the tube c and ehamberf and pipe I) to the tender or tank, thus Warming the water therein to the extent desired. Now, to start the injector under these conditions, the valve G is opened to admit sufficient steam to drive the water out of the pipe D back into the tank, and then by quickly opening the valve H the steam is permitted to escape at the overflow, thus relieving the pressure in the supply-pipe D and permitting the water to enter the said pipe D by virtue of its own gravity. The water, in passing from the tank or tender to the lowest point of the supply-pipe D, obtains sufiieient velocity to cause it to flow into the chamber-f, where it is acted upon by the steam issuing from the tube e, the water being thereby accelerated and the jet established suficient to deliver the water to the boiler. For the perfect operation of the apparatus provision must be made for the free escape of steam, and this I accomplish by the use of the perforated plate g.
It will be seen that the principle employed in the operation of this injector is entirely different from that of the ordinary injector, and is only applicable to an automatic injector of the description set forth, in which special provision is made for the free escape of steam at the overflow. Ordinarily there is no communication of this sort, and the steam passes only through the combining tube. Where this is the case the exhaust would be too sluggish, and the water would not obtain sufficient velocity in entering the pipe Dto raise it to the chamber f.
By my construction, herein set forth, the Water can be lifted no matter how highly heated.
The steam-valve G has a stem, h, on which the plug or valve proper, c', is arranged. This stem 7i has a hand-Wheel, j, for operating it. The stem h has a screw-threaded bearing in a boss, k, arranged upon a yoke, I, and this yoke terminates in a screw threaded nut, m, by which the yoke is secured in the Valve-shell o,
'thestem being provided With a gland, p, which,
by means of the yoke, is accessible from the outside for operation by means of a Wrench, thus obviating the necessity of removing a bonnet' to get at the gland.
Vhat I claim is- 1. A locomotive-injector having a steaminlet and connections with the steam-space of In machines l the boiler, a valve therein, a Water-inlet, and connections with the tender, a controllingvalve interposed between these two inlets, a combining-tube, boiler-connections f or introducing feed-Water, and a check-valve interposed between the boiler and overflow-valve, combined with a quick-acting overflow-valve, substantially as and for the purpose set forth.
2. An injector comprising a steam-inlet and valve therein, a Waterinlet, a controllingvalve, check-valves a and I, a combining-tube, and a quick-acting overflow-valve, combined and arranged substantially as set forth.
3. An automatic injector for locomotives, comprising a steam-inlet and a Water-inlet, an interposed steam-supply pipe, a combiningtube, a quick-acting overflow-valve, and auX- iliary steam-passages between the combiningtube and boiler, substantially as described.
4. A valve, G, having'a threaded stem, combined with a yoke provided with a threaded boss at one end engaged by said threaded stem and an internally and externally threaded nut, m, at the other end, and a gland accessible from vthe outside of the yoke and valve, substantially as described.
In testimony whereof I have hereunto set my hand this 14th day of April, A. D. 1887.
