RALPH ROVER LAMB, OF CHICAGO, ILLINOIS.
VALVE Application filed December 19, 1904. Serial No. 237,553.
To all whom it may concern:
Be it known that l', RALPH Rovnn LAMB, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Valve, of which the following is a specification.
This invention has particular relation to float-operated valves or ball-cocks for fiushing apparatus, though perhaps useful for other analogous purposes.
One of the objects is to provide valve mechanism of a novel and simple nature that is balanced by the pressure of water, so that no great power is necessary to operate the same' and such power can remain constant,
Another object is to provide mechanism which can v be readily employed either as a manually started or as an automatic periodically operated flushing apparatus.`
Two embodiments of the invention are illustrated in the accompanying drawings, wherein: Figure l is a sectional View through a tank, showing one of said embodiments in elevation. Fig. 2 is a sectional view on an enlarged scale through the mechanism. Fig. 3 is a cross sectional view taken on the line 3-3 of Fig. l. Fig. 4 is a detail top plan view of the joint between the arms of the float lever. Fig. 5 is a detail perspective view of the valve stem with the valve and pluger. thereon. Fig. 6 is a sectional view through the other embodiment of the invention. Fig. 7 is a top plan view partly in section, showing the joint between the sections of the arm.
Similar referencenumerals designate corresponding parts in all the figures of the drawings.
Referring first to the embodiment shown in the first ve figures, the tank 8 illustrated may be of any well known form or construction and located within the same is a casing 9, having a chamber 10 therein, and` provided with a depending nipple 11, extending through the bottom of the tank and suitably secured by a nut and washer 12 and 13. This nipple is provided with a water supply inlet conduit 14, to which may be attached the supply pipe from a water main. ing a part ofthe casing 9, and preferably made integral therewith is a guide cylinder 15, the inner end of which is open and communicates with the chamber 10, the outer end being also open and communicating directly with the interior of the tank. Another guide cylinder 16 is located in the opposite end of the casing 9, being preferablyl threaded therein, and having its bore of equal diameter with thebore of the cylinder 15. The inner portion of the cylinder y16 projects into the chainber 10, and has its inner end communicating therewith, while its outer end is :formed into a depending spout or nozzle 17, that opens downwardly into the Specification of Letters Patent.
Form-- Patented July 2, 1907.
tank. The inwardly projecting portion of the cylinder 16 is spaced from the surrounding walls'of the chamber, and formed in the side walls of said cylinder is a series of water ports 18, that are preferably, though not necessarily, disposed in spiral relation, as illustrated in Fig. 2. Extending longitudinally through the casing and through the cylinders is a valve stem 19, that is'longitudinally slidable and carries a plunger valve 20, located in the guide cylinder 16 and movable to positions on opposite sides of the opening or ports 18 when the stem is moved. Said plunger valve comprises a guide nut of'equal diameter with the cylinder bore, and a cup abutted against the inner side thereof, and also of equal diameter with the bore, as shown. Secured to said stem 19 and located in the other cylinder 15 is a plunger 21, that is also in the form of a guide nut and cup, both engaging the cylinder walls, said plunger and plunger valve being of equal diameter. One end of the stem 19 projects through the head of the spout 17 and secured thereto is a yoke 22, in which is engaged the lower end of an arm 23, pivoted between its ends upon an ear 24, carried by the casing or spout head. The arm 23 constitutes, in effect, one section of a float lever, the other section being in the form of an arm 24h, carrying at its free end a iioat or ball 25. These arms are pivotally connected at their Vadjacent ends, said ends being provided with heads 26, having circular series of interfitting teeth 27, which normally hold the sections or arms against relative pivotal movement, the heads being united by means of a pivot and holding bolt or screw 28. A separate outlet from the chamber within the casing is through a pet cock 29, having a turning plug 30, by means of which this outlet is controlled.
Assuming that the parts are in the relation shown in Fig. 1, and that there is no water in the tank, will be evident that the float or ball 25, being depressed, will hold the valve and plunger in the position shown in Fig. 2. Therefore, water entering the casing through the inlet 14 can pass freely through the ports .18, and thus into the cylinder 16, from which it escapes through the spout 17 into the tank.` As the level of the water in said tank rises, the float 25 will, of course, be elevated, and the ports 18 thus be successively cut off from the spout by the movement of the plunger valve 20 to positions between said ports and the spout. Consequently, the supply of water will be gradually cut off, without any hammering or quick action on the part of the valve.
Moreover, it will be clear that the plunger and plunger valve being of equal diameter, the pressure of the water on the valve mechanism will be exactly balanced, and it will require merely the buoyancy ofthe float to close the same and the weight of said float to open the valve, no matter what the water pressure may be. This is an important feature of the invention, particularly when the simplicity of the structure is taken into consideration. The mechanism as thus arranged is, oi course, ior use in connection with manually started ilushing apparatus. In case it is desired to employ the mechanism `for automatically flushing at stated periods, the arm 24b of the iioat lever is released from the arm 23 by loosening the screw 28, and said arm 24" is swung to an opposite position or to the position indicated in dotted lines in Fig. 1. It will therefore be clear that, when thus arranged, with the ball or lioat in its lowermost position, the supply of water will be cut off, and said supply is only admitted to the tank through the spout 17 when the float is elevated. The pet cock is thereupon opened to any suitable degree desired, in order to allow the continuous iiow of water. With this arrangement it will be apparent to those skilled in the art that, as the level of the water rises, due to the flow into the tank through the pet cock, the iioat will also be gradually raised, and, when the level of said water is high enough to begin the usual siphon action, the float is so arranged that it will automatically open the main supply. Thereupon the Siphon will be started and will not be broken until the water has been discharged from the tank and the valve 20 again moved to closed position. From this it Will be seen that simple mechanism is provided which can be employed either in connection with manually started or automatic periodic flushing apparatus.
The other embodiment, illustrated in Figs. 6 and 7, has substantially all the advantages hereinbefore set forth. lt comprises a casing 9, having a chamber l0, and a nipple 11, through which a iiuid supply opening l2 leads to said chamber. An upstanding guide cylinder 13, carried by the casing 9, has its inner end communicating with one end of the chamber, while another guide cylinder 14 communicates with the other end otthe chamber and projects into the same, as shown at 15, the portion ot said chamber surrounding the inwardly extending end of the cylinder 14 being preferably enlarged, as shown at 16 in order that the Walls thereof may be spaced from the Walls 15. Said Walls 15 are provided with the usual spiral series of ports 17, constituting means oi communication between the chamber 10 and the interior of the cylinder, said cylinder having its outer end communicating with the downturned discharge spout 18 A valve stem 19, mounted to slide longitudinally in the cylinder 14, is provided with a cup valve 20, movable to positions on opposite sides of the ports 17, while in the cylinder 13 is a sliding plunger 2l, carried by a stem 22, the plunger-and valve being equal in diameter, the two cylinders thus being also equal in diameter. Mounted on an intermediate portion oi the casing 9 is a standard 23, upon which is mounted a lever 24 that is pivoted between its ends, this lever having itsarms respectively connected to the stems 19 and 222i. Each of such arms constitutes, in effect a section oi a float lever, the other section being an arm 25, that carries at its free end a float or ball, while its opposite end is pivoted, as shown at 28, to one of the arms oi the lever 25. The said lever 24 and float arm 25 are thus capable of adjustment but are ordinarily held against the same by means of a suitable bolt 26, carried by the arm 25, and irietionally engaging a quadrant 27, carried by the lever, said bolt passing through the quadrant, as shown in Fig. 7.
With the parts as shown in Fig. (l, it will of course be understood that the supply oi water is cut oil trom the tank when the iloat is raised, but when employed in automatic flushing apparatus, the arm 25I is merely changed to the opposite end oi the lever 2li, as shown in dotted lines in Fig. G, the casing 9 being provided with a pet cock 25) that communicates with the cli-.unber 10.
lt is believed that the operation oi this structure will be readily understood and that a iurther detailed description thereof is therefore unnecessary.
From the foregoing it is thought that the construction, operation, and many advantages of the herein described invention will be apparent to those skilled in the art, without iurther description, and it will be understood that various changes in the size, shape, proportion, and minor details oi construction may be resorted to without departing from the spirit or sacri ficing any oi the advantages oi the invention.
