ELECTRICALLY-CONTROLLED VALVE.

Specification of Letters Patent.

Patented Apr. 18, 1916.

Application filed September 27, 1913.' SerialZNo. 792,194.

To all whom it may concern: I

Be it known that I, LEWIS A. MAPEL, a citizen of the United States of America, residing in the city of 'St. Louis and, State of Missouri, have invented certain new and useful Improvements in Electrically-Con- Another object is to provide improved .means for controlling a valve which is 'located in a liquid supply pipe, said'pipe being adapted-to discharge in't'oa receptacle when the valve is opened so that'the valve will be automatically closed when the desired amount of water has been obtained in the receptacle.

A further object is to provide improved means whereby a valve located in a supply pipe can be opened todifferent extents and when the predetermined amount of liquid has passed by said valve, said valve is' alltomatically closed.

Other and further objects will appear in the s ecification, and he specifically mentione in the appended claims, reference being' had to the accompanying drawings exemplifying the invention, and in which, v

Figure 1 is a side elevation showing this improveddevice connected up with a receptacle. Fig. 2 is an'enlarged fragmentary view showing the water column tube in section, and a portion ofthe valve casing of the water supply pipe broken away. Fig. 3 is an enlarged section taken on the line III- III of Fig. 2.

Referring tothe drawings: 1 designates a receptacle to which is connected a water column 2, said column communicating wgch e.- cured to said column 2, is a gage rod 4, said rod having slidablymounted thereon a block 5, said block adapted to be adjustably held on said rod by the set-screw 6. Se-v cured to said block is an electrical contact 7, and pivotally mounted to said block at 8 is a contact lever 9, said contact points being located adjacent each other. Communicating with said receptacle 1 is a water supply pipe required,

10, and forming a part of said supply pipeis a valve housing 11, said housing having a preferably inclined valve seat 12 formed therein, in which is mounted a valve 13. Extendlng transversely and horizontally through said housing 11, and having its bearings in the outside of said housing, is a p1n14: Secured to said pin adjacent the center thereof and in the housing 11 is a lever 14', the end of said lever being connected to the depending portion 15 of said valve 13 by the pivotal connection 16. Mounted on one end of said pin 14, on the outside'of said housing 11, is a hand lever 17, the hub portlon 18 of said hand lever having formed thereon a series of ratchet teeth 19. Pivotally mounted at 20 to one side of said housmg 11 is a lever 21, said lever.having formed thereon a pawl 22, and at the opposite end of said lever is mounted a magnet attracting portion 23. Depending from the under slde of said housing 11 is a bracket 24, said brackethaving secured thereto an auxiliary bracket 25. Secured to said bracket 25 are apair of vertically mounted magnets 26, the upper ends of said magnets being located adjacent the under side of said magnet attracting portion 23 of said lever'21.

Pivotally mounted at 27, to the bracket 25 is a lever 28, and secured to said bracket adjacent one end of said lever 28, is an electrical contact 29. Pivotally mounted at 30 tothe lever 21 is a link 31, the opposite end of said link being pivotally mounted at 32 to the lever 28, formed in said link 31. At the end, which ,is connected to the pivot 30 is an elongated opening 33. Secured to said lever 21 is one end of a coil spring 34, the opposite end of said spring being connected to the housing 11. Electrically connected to the contact point 9 is a wire 35, the opposite end of said wire being connected to the lever 28.

Leading from magnets 26, is a the contact 29 to one of thewire 36, and leading from 37 is a wire 38. Leading from the contactpoint 7 to one of the line wires 37 is a wire. 39. Movably mounted in the column 2 is a float-40, said float having verticall mounted therein a push-rod 41.

This improved device is used more as:- pecially where large amounts of'water are said amounts having to be regulated in accordance with prescribed amounts to be obtained in the receptacle 1, this amount of water being predetermined, the sliding block 5 is set in accordance therewith on the gage-rod 4, The hand lever 17 is then manipulated, and the valve 13 is elevated from its seat 12. The water in the supply pipe 10 will then pass under the valve and into the receptacle 1. As the water rises in said receptacle, the same water level will be attained in the column 2.

n. The rising of the water in the receptacle will elevate the fioat 40 in the column 2, thus carrying the rod 41, and the upper end thereof will contact with and lift the contact lever 9 until said lever engages the contact 7 This contact of said contacts 7 and 9 will energize the circuit in which this improved device is located, thus energizing the magnets 26 and drawing down the portion 23 of the lever'21, which movement will elevate the pawl 22 from the ratchet teeth 19. This elevating of the pawl 22 will unlock the elevated position of the valve 13, and the pressure of the water in the supply pipe 10 hearing against the upper side of said valve 13 will immediately seat said valve on its seat 12, thus closing off further discharge into the receptacle 1. As the lever 21 was being drawn down by the magnets 26, the pivot 30 of said link 31 moved freely in the elongated opening 33. But before the contact portion 23 of said lever 21 engaged said magnets 26, said pivot 30 reached the lower end of the opening 33, and the link 31'was moved downwardly. This movement of said link 31 displaced the lever 28 from contact with the contact 29, which movement of said lever 28 from said contact 29 denergized the circuit. The lever 21 would then be returned to its normal position by the spring 34.
