SPECIFICATION forming part of Letters Patent N0. 468,209, dated February 2, 1892.
Application led April l, 1891. Serial No. 387,282. (No model.)
T0 @ZZ whom it may concern:
Be it known that we, HEINRICH RAUSEE and CHARLES WIEBEE, subjects of the Emperor of Germany, and ALEXIS SOKOLOFF, a subject of the Czar of Russia, all of Moscow, Russia, have invented a new and Improved ioiler-Feeder, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved boiler-feeder which is simple and durable in construction and very effective and automatic in operation.
The invention consists of an ejector controlled by a float in the boiler and adapted to control the feed-pump.
The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.
Reference is to behad to the accompanying drawing, forming a part of this speciiication, in which the figure is a sectional side elevation of the improvement as applied.
In the boiler A is arranged a iioat- B, provided with au upwardlyextending hollow stem C, passing through a pipe D, held in a casing E, secured on the shell of the boiler, as plainly illustrated in the drawing. Near the upper end of the stem C is arranged a disk F, adapted to engage with its periphery one arm of a bell-crank lever G, fulcruined in the casing E and carrying on its other arm a valve II, leading to an ejector I, of any approved construction, provided with the usual nozzle I and the cone-shaped mouth I2. Into the ejector I leads a pipe J below the nozzle I', the said pipe .I being connected with a casing K, from which leads a pipe L to the valvechamber N of the feed-pump N. In the valve-chamber N' is held a suction-valve N2. Over the suction-pipe N3 and directly above the suction-valve N2 is arranged a dischangevalve N4, connected with a discharge-pipe N5, leading to the interior of the boiler A. The pump N is continually in operation; but as soon as the valve II is closed and the ejector I is not working the suction-valve N2 remains seated, as the valve-chamber N is connected with the outer air by the pipe L, the casing K, and the pipe J, connected with the mouth I2 of the ejector. In the casing K is arranged a float O, provided on its upper end with a valve C', adapted to be seated on a valve-seat K', formed in the upper end of the casing K at the entrance of the pipeJ to the said casing. On the lower end of the lioat O is also secured a valve O2, adapted to be seated on a seat K2, formed in the lower end of the casing K and connected with an S-shaped outlet-pipe K3, containing a ball-valve K4. Then the water in the boiler A sinks below the normal level, the float B slides downward with the falling of the level of the wat-er, thereby moving the disk F on its stem C into contact with an inoline on the bell-crank lever G, so that the latter is actuated and the valve II is raised off its seat. Steam from the boiler can now pass through the pipe D, the upper part of the Casin g Il, past the valve I-I, into the ejector I, so that air is drawn through the pipe J into the ejector and a vacuum is consequently formed in the valve-chamber N of the feedpuinp. As the latter is continually in Operation, water will rise in the suction-pipe N3, pass into the pump past the valve N2, part of the water passing into the casing K, in which the float O is caused to rise by the incoming water until finally the valve O seats itself on the seat K', thereby closing the pipe J, t-he valve O`2 seating itself on the seat K2, so as to close the outlet or discharge pipe K3. The pump N now operates in the usual manner, forcing the water past the outlet-valve N4 into the outlet-pipe N, so that the water is pumped into the `boiler A. IVhen the water has risen in the boiler A to the normal level, the doat B has risen upward with the water and the disk F is again brought back to its former normal position above the incline on the bell-crank lever G. The valve II is thus again seated on its seat and the ejectorlstops working. As soon as the ejector stops working the pressure in the pipe J on the valve O causes the iioat O' to move downward, the said valve O having a larger area than the valve As soon as the valves O and O2 are unseated the water in the casing K iiows through the outlet-pipe K3, whereby the air entering the pipe J again passes to the valve-chamber N', so thatthe valve N2 remains seated on the ICO further working of the pump and no water is' the cylinder, the former through the mouth l2 andV pipe .I and the latter from the casing K, as the vacuum above the valve O ceases as soon as nthe steam is shut off from ejector i by the seating of valve H, as above mentioned. The float O consequently sinks and the pump only -sucks in air through ejector I, -pipe- J, casing K, and pipe L until the ejectoris again actuated and produces a vacuumV above the valve 0. Y
In case the valve'II or otherparts described are out of order and the pump should not force the necessary amount of Water into the boiler, as above described, then the water in the boiler will sink to a dangerous level. In order to warn the operator of the danger, the following device is provided: A second bellcrank lever P is pivoted in the upper end of the casing E and is provided on its vertical arm with an incline arranged a suitable distance .below the incline of the bell-crank lever G, arranged opposite the lever P. The horizontal arm of the bell-crank lever P carries a valve Q, connected with a Whistle R,so that when the water sinks to a dangerous level in the boiler the doat B moves downward, and the disk F, acting on the bell-crank lever I), causes .the valve yQ to be unseated and steam is Afree to pass from the boiler to the whistle R to sound the same, thus giving the signal.
To prevent too much water Ifrom being pumped into the boiler A by the feed-pump N, the following device is provided: 0n the stem C is arranged a valve S, adapted to be seated on a valve-seat D', formed on the lower end of the pipe D, establishing communication between the interior of the boiler A and casing E, as previously described. New when the water rises to its maximum level in the boiler A the valve S seats itself on the seat D of the pipe D, so that steam cannot pass to the casing E and to. the ejector I, so -that the operation of the pump N ceases, as previously explained.
In order to permit the float B to fall with the receding water in the boiler A, a valve T `is provided formed on the extreme upper end of the hollow stein C and adapted to be seated on a valve-seat E', arranged in the cap of the casing E. Vhen the valve S is seated on its seat, the valve T is likewise seated on its seat E. Now as soon as the water recedes in the boiler A the steam passing through the apertures C in the hollow stem C to the valve T presses on the latter, so that the pressure on the valve S is equalized and the float B is tree to sink with the falling Water. It will thus be seen that the boiler-feeder is completely automatic in operation, prevent-s a dangerous iilling ot the boiler, and also gives a signal in case the water should sink 'to a dangerous level. v
