Application filed November 19,1914. Serial No. 873,074.

I T (ill whom it may coi'wcrn;

Be it known that I, "VILLIAEI' D. HUFF, a citizen of the United States, residing in the city of La Fayette, parish of Lafayette, and State of Louisiana, have invented certain new and useful Improvements in Automatically-Controlled -Pumping:Stations; and I do hereby declare the following to be a full,

clear, and exact description ofthe invention,

'such as will enable others skilled in the art.

to'whieh it appertains to make and use the same.

My invention relates to apparatus designed to automatically start and stop a gasolene or internal combustion engine, for the purpose ofdriving a pump or other means for lifting water, operated by such engine; and also to prime the water pipes before each operation and to drain the pipes and pump after each operation, whereby the danger :from freezing is avoided, and the. inconvenience and danger, due to water remaining inthe operative parts. when not required, is avoided and the apparatus is further .-adapted to automatically take careof itself and operate in the absence ofan attendant, and without any care or. attention..for a period of several days at a time.

- My invention particularly. relates to pumping plants, such as are .used by railroads to supply water to locomotives; and it also relates to pumping plants used by farmers and others, where water is elevated and stored, and it. is desired to automatically replenish the supply so stored as his used.

The whole an mratus is primarily driven by the engine l), and the engine and other ice parts are, automatically controlled bfa'the' float K, which float is divided into two chambers by the partition k, shown .in Fig. 1,

and;has a drain nozzle k which will drain '5" the upper chamber, of the float when the pump ,0 is not. acting; but will not drain vthe liquid out of the upper chamber of the .float as fast as it is supplied by the pump C 1 when the latter isin operation. Attached to the bottom of, the float K is the operating rod-S, which passes through a stnlfing box a, in the bottom of the 'tank A, and also throughjaguide b carried by-the framework B. T nis rod S has two tappets 1 and 2, in the form of sleeves, adj ustably mounted thereon, which are held in the desired position by means of the set screws 3 and 4, re- :1 spectively. The two ends of these tappets 1" and 2 are preferably in the form of frus- 2o.-"tum s of cones 5, and these tappets engage.

.the'rollers 6 and 7 carried by the bell crank levers 8 and 9 which are pivoted to the bracket 10 carrying the switch block 11 and the switch lever 12. The tappet 1 is some- 1&5 what-more elongated than the tappet 2, for

reasons that will be hereinafter described.

The inner arms 8 and 9 of the bell crank levers 8 and!) engage the two ends of the switch lever 12, and the arm 8 presses against the stem'13 of the check valve 14v which controls the flow of water to the water Y motor through the pipe M. This check valve 14 is normally held on its seat by the spring 15, except when pressed back by the arm 8 of the bell crank lever 8, as will be hereinafter described. The pipes J and M are connected by a by-pass 16, controlled by a check 'valve, in the valve chamber 17, which, when the valve 14 is open, permits" water. to flow across this by-pass 16 to the pipe J and down said pipe into the pump C,

priming the same and, incidentally, fillifng' the pipe I so that'the pump will be primed 1 and ready to start when the water motor begins to start theengine; but this check valve in thech'amber 17 will prevent the return from the pipe J through said by-pass 16, after the valve 14 is closed, and while the pump C is running. The engine is water 4 cooled by a pipe 18 connected to the delivery pipe J, and the hot water is drawn oii by the pipe 1S).

Oil is supplied to the engine from the tank F through the valve seat 20, past the valve 21 and through the chamber 2-2. The valve 21 is carried by the float 23, which is adapted to close the valve port when the chamber 22 is filled with oil above a predetermined height, but should the valve stick for any reason, I provide an outlet 24 connected to the oil drain pipe 25, which, is connected to the oil-waste-tank G. The ,height'of the opening of the orifice 24 is below the level -of the earbureter26, which is connected to jibe chamber 22 by means of the pipe 27 so that if there is any excess of flow of oil from thetank F to the chamber 22, the excess will be taken care of by the drain pipe .25 and will not run into the engine.

but electrically connected therewith when the lever 12 is thrown to the operative position. This contact piece 35 is connected to the timer 36, for timing the spark, which is effected in the usual well known way, but is 5 shown diagrammatically only in Fig. 2.

When it is desired to have an audible signal, I provide an electric bell P whose cireuit is closed through the battery by means of the spring 40, which is normally held clear of, but is pressed down on the contact button 41 and completes the electric circuit when the tappet 1 approaches the guide 12. Where a visual signal is required, I may use a semaphore N, operated by the cord or 5 chain 50 which passes over the pulleys 51 and 52 and is connected, as at 53, to the float K. l/Vhen the float is in the raised position, the semaphore will obviousl fall to the position indicated in full lines in Fig. 1, and when the float is lowered the semaphore will be raised to the position indicated by dotted lines in Fig. l, which will occur when the level of the water in the tank is lower than is desired.

The operation of the device is as follows: Assuming the pump to be at work filling the tank when the water reaches the desired height in the tank A, the lower tappet 2 will be lifted, engaging the roller 7 and rocking the bell crank lever 9, throwing the lower end of theswitch lever 12 outward and swinging the arm 8" of the bell crank lever 8 clear of the stem 13 of the check valve 14; and this will also cut off the current from 1 the igniter, and the engine will stop, while at the same time the check valve 14 will close the pipe M and the entire apparatus will be thrown out of operation. Water may now be used from the tank A until the levelfalls so low that the float K will cause the tappet l to descend, engaging the roller 6 ofthe bell crank 8, throwing the arm 8* of the bell crank lever outward, pressing the stem 13 of the valve 14 against the action of the spring 15, and opening the check valve 14. At the same time the check valve in the chamber 17 will open, permitting water to simultane- .o'usly flow across the by-pass 16 into the mitting water to flow down the pipe M to the Water motor E, and will cause the water a between the contact pieces 34 and 35, and the igniter will be in operation. The engine will now start up, and the pump C, being primed and put in operation, will pump water up through the pipe J and flowing through the bent end j of said pipe, the water will fall into the upper chamber of the float and will soon fill this up, gradually depressing the float still farther down and causing the tappet 1 to pass entirely below and clear of the roller 6, at which time the spring 15 will restore the valve 14 to the closed position and the water motor will be thrown out of operation. The pumping will continue until the float rises high enough again to cause the lower tappet 2 to engage the roller 7 and throw the switch lever 12 to the position for cutting off the current. As the tappet 1 rises with the float, it will press up the roller 6, keeping the lower end 8 clear of the stem 13 of the valve 14, and also clear of the switch lever 12. The operation of this roller 6 may be facilitated by having an oppositely-disposed guide roller 6, which latter has no function in the operation of the apparatus except to center the tappet 1 and hold it up against the roller 6. The water will continue to flow into the water motor only while the elongated tappet 1 is bearing on the roller 6, or long enough only to get the engine started. Vv'hen the float falls down to an abnormally low position, the tappet 1 will press on the contact spring 40, willclose the bell circuit and ring the bell P, or Will lift the semaphore N from the lower to the raised position, thus giving either a visual or an audible signal that the supply water is low in the tank. It will be noted that the extra weight of water thrown on the float K by filling the upper chamber of said float will continueto hold the float down, so long as the water is flowing into said chamher from the orifice j faster than it flows out through the drain in; but when the pump (1 stops, the water inv the upper chamber of the float will drain off through said drain la, and the normal buoyancy will be restored to the float. The maximum height of liquid in the tank A may be automatically controlled by adjusting the position of the tappet 2 on the rod S, and the minimum level of the liquid in said tank may be automatically controlled by adjusting the position of the 'tappet 1 on the rod S.

In order to permit the pipe I to be filled with water, as in the priming of the pump. and vet to permit this water to drain oft when the pump is not in operation, I provide, besides the ordinary flap valve i above the strainer I in the pipe I. a small check valve I opening outward. which will allow any water that accumulates in said pipe to flow out into the main body of the water in the reservoir; while any water remaining in the water motor runs oil", of course, through the drain pipe 6. Thus it will be seen that when the water falls below a predetermined level in the tank A the float will descend low enough to cause the tappet 1 to open the check valve 14, and will complete the electrical connections, and will also open the by-pass 16; thus simultaneously starting up the water motor and the engine, and priming and starting up the pump. As soon as the pump begins working, it will fill up the chamber in the float, partly sinkingthe same and throwing, the tappet 1 out of engagement, and permitting the check valve 14 to return to the closed position; thus cutting oil the supply of Water to the water motor, but without in any way aflecting the electrical connections, or the running of the engine or the pump. In this way only a small amount of water is used from the tank for starting the engine, and the feed to the water motor cut oli soon after the engine starts. Should the level of the water get lower than is desired, the signaling apparatus will be automatically thrown into operation and the proper signal will be made. After the tank is tiiled up again, the lower tappet engaging the roller 7, will cut oil the current and stop the engine, and the water in the pump and in the pipe I will be allowed to drain out through the check valve I In Fins. 1 and 2 I have. shown a pump mounted on a horizontal. shaft counwted directly with the main shaft of the engine; but in Fig. 5 I have shown an engine shaft provided with a gear wheel 60, mesliing with a gear wheel 61. on the pump shaft in which case the pump shaft is rertirai, and this construction may be yu'eierable under certain conditions; but i do not mean to limit myself to any panicular i'oim or arrangement of parts, or to any particular form of engine, or gearing for same, or other parts of the apparatus except as part arly set out in the claims \Vhile I have shown the apparatus all located at the same station, it will be obvious that the pumping plant, and especially the oil supply and oil drainage tanks, may be located at any reasonable or convenieiit distance from the water tank. In railway service it is specially desirable not to have any large quantity of oil or other inflammable material close to the tracks, or to buildings near the tracks, and therefore it is specially desirable to feed the oil from a distance. and to prevent any leakage of oil at the plant. which is all provided for in the ap 'iaratus herein described.

It will be obvious that various modifications might be made in the herein described apparatus and in the construction, combination and arrangement of parts which could be used Without departing from the spirit of my invention.
