\VILLIAM A. SEMANS, OF NOBLESVILLE, INDIANA.
BOILER OIL OR COMPOUND FEEDER.
$PECIFICATION forming part of Letters Patent No. 574,765, dated January 5, 1897. Application filed July 16, 1896. Serial No. 599,383. (No model.)
To all whom, it may con/corn:
Be it known that 1, WILLIAM A. SEMANs, a citizen of the United States, residing at Noblesville, in the county of Hamilton and State of Indiana, have invented a new and useful Boiler Oil or Compound Feeder, of which the following is a specification.
My invention relates to an improvementin devices for introducing oil or other purge into a boiler.
The object of my invention is to produce a device'which shall be automatic in its operation, and one in which the oil or other purge shall be drawn from its reservoir by means of the suction of the pump, the said oil passing through the Water-cylinder of the pump and thereby acting to prevent all scale formation in the pump as well as in the boiler.
The accompanying drawing illustrates my invention, the figure being a central vertical section thereof.
In the drawing, 1 indicates a reservoir adapted to receive the oil or other purge, the said oil being introduced through an opening 2, provided with a suitable plug, a vent-cock 3 being provided to facilitate the entrance of the oil. Mounted on the side of the reservoir and communicating with the interior thereof through the usual valves is a gageglass 4 of the usual form.
Secured to the bottom of the reservoir 1 and communicating with the interior thereof is a short pipe 5, upon the lower end of which is secured one half, 6, of a coupling, the other half, 7, of said coupling being secured to the upper end of a valve 8, upon the lower end of which is formed a short nipple 9, which projects into the sight-glass 10, the said glass being mounted in the usual manner between valve 8 and a coupling 11. To the lowerend of coupling 11 is secured a pipe 12, in which is mounted a valve 13, the said pipe 12 communicating with the suction-pipe of the pump used in forcing the water from the well or feed-water heater into the boiler. Secured to the upper end of part 7 and passing upward through pipe 5 into reservoir 1 is a pipe 14:, the open upper end of which reaches nearly to the top of the reservoir. A pipe 15 passes through the upper end of the reservoir and extends nearly to the bottom thereof. To the upper end of pipe 15 is secured a valve 16, and above this valve and communicating therewith is a condensing-chamber 17, into the upper end of which is led a steam or pipe 12 between valve 13 and coupling 11,
and mounted in said pipe is a coupling 21 and a suitable "alve 22, said valve remaining normally closed.
The operation is as follows: A supply of oil or other boilcr-purging compound is introduced into reservoir 1 through opening 2, vent-cock being opened to facilitate the entrance thereof, and when the reservoir is filled opening 2 and cook 3 are closed. Valve 13 is then opened and the suction of the pump creates a vacuum in pipe 12 and sight-glass 10. Valve 8 is then opened enough to allow the oil to be drawn down through pipe 14 and out through nipple 9, the said oil passing down through pipe 12 and into the suctionpipe of the pump, where it becomes mixed with the water and passes into the water-cylinder of the pump and from there passes into the boiler. As soon as the oil begins to pass from nipple 9 valves 16 and 19 are opened and either steam or water is allowed to pass through pipe 15 into the interior of the res ervoir. In the preferred construction steam is allowed to pass through pipe 18, and as it reaches chamber 17 it is condensed and then passes down through valve 16 and pipe 15 into the lower end of the reservoir, the oil floating upon the top of the water and being thus lifted up, so as to constantly cover the upper end of pipe 14. introduced through pipe 18 does not come under any considerable pressure and serves merely to lift the oil in the reservoir and has not sufficient pressure to force the said oil out through the nipple, said action being entirely 5 due to the suction of the pump.
By the above-described construction the upper end of pipe 14 is kept constantlycovered either with oil or water, so that in case of neglect by the engineer there is no possibil- 10o ity of the pump sucking air through the feeder; When it is desired to introduce a new charge of oil into the reservoir, valve 8 is closed and valve 22 is opened, the water The steam or water from the reservoir being then withdrawn by the pump through pipes 20 and 12. lVhen a sufficient amount of water has been withdrawn, valve 22 is closed, oil is introduced through opening 2, valve 8 is again opened, and the operation continues.
\Vith the arrangement of parts as de scribed the purging material is caused to first pass through the watercylinder of the pump, thus keeping the parts of said cylinder free from scale and preventing the parts from becoming inoperative, a ver common occurrence in the ordinary construction, where the water is pumped from a feed-water heater. By this construction also a perfectly dry feed is obtained, the purging fluid being withdrawn from the reservoir by means of the vacuum created in the sight-glass by means of the pump, instead of being introduced into the discharge-pipe of the pump against the pressure thereof, as in the ordinary construction. Again, a constant supply of water being introduced into the reservoir to take the place of the oil as it is withdrawn there is no possibility of the pump sucking air through the feeder, the upper end of pipe 14 being always covered either with the purging compound or with water.
By means of couplings 6, 7, and :21 the reservoir may be easily and quickly disconnected, pipe let being withdrawn through pipe 5.
I claim as my invention- 1. In a boiler oil or compound feeder, the combination with a reservoir adapted to contain said compound, of a discharge-pipe leading therefrom near the top thereof, a nipple formed on the outer end of said pipe, a vacuum-chamber formed around said nipple and communicating with the suction-pipe of a pump, and an inflow-pipe through which Water may be introduced into the reservoir near the bottom thereof, all combined and arranged to cooperate substantially as and for the purpose set forth.
2. In a boiler oil or compound feeder, the combination with a reservoir adapted to contain said compound, of a discharge-pipe leading therefrom near the top thereof, a vacuumchamber formed about the discharge end of said pipe and communicating with the suction-pipe of a pump, an inflow-pipe through which water may be introduced into the reservoir near the bottom thereof, and a second discharge-pipe, provided with a suitable valve, leading from the reservoir near the bottom thereof, all combined and arranged to cooperate substantially as and for the purpose set forth.
3. In a boiler oil or compound feeder, the combination with a reservoir adapted to contain said compound, of a discharge-pipe leading therefrom near the top thereof, a nipple formed at the discharge end of said pipe, a valve mounted between said reservoir and nipple, a sight-glass mounted over the end of said nipple and forming a vacuum-chamber adapted to be connected with the suction-pipe of a pump, and an inflow-pipe through which water may be introduced into the reservoir near the bottom thereof, substantially as described.
4. In a boiler oil or compound feeder, the combination with a reservoir adapted to contain said compound, of a discharge-pipe leading therefrom near the top thereof, a nipple formed at the discharge end of said. pipe, a valve mounted between said reservoir and nipple, a sight-glass mounted over the end of said nipple and forming a vacuum-chamber adapted to be connected with the suction-pipe of a pump, an in flow-pipe through which water may be introduced into the reservoir near the bottom thereof, a con(lensing-chamber connected with said inflow-pipe, and a second discharge-pipe, provided with a suitable valve, leading from said reservoir near the bottom thereof, all combined and arranged to cooperate substantially as and for the purpose set forth.
5. In a boiler oil or compound feeder, the combination with a reservoir adapted to contain said compound, of a pipe 14-, valve 8, nipple 9, sight-glass 10, and intermediate connections adapted to form a communication between said glass and the suction-pipe of a pump, pipe 15, and discharge-pi pc 20 provided with a suitable valve, all combined and arranged to cooperate substantially as and for the purpose set forth.
