To all when?, it may concern: y

Be it known that "Roscoe H. Anoniem, a citizen of the United States, and a resident of Allentown, in the county o1 Lehigh andn State of Pennsylvania, have-invented a new and improved Valve, ot which the following a tull, clear, and exact description.

This inventionrelates toI valves, and particularly to rotating water valves designed to be used inpumps and other similar places where water is forced or drawn through a. valve.

The object in view is to provide a. newl and improved structure which will be automatically actuated by the water passing through the valve for causing the movable part of the valve to seat at a different. place upon each opening and closing ot the valve.

Another object of the invention is the double discharge opening valve in combination with wings placed at. au angle so as to be engaged by liquid passing through the inner discharge opening for causing a rotary movement ot' the movable part of the valve whereby the same seats' itself at a diierefit place upon each opening and closing.

In carrying out the objects of the invention, a valve seat is provided designed to receive a4 retaining pin upon which is rotatably mounted a movable valve member carrying a washer adapted to Contact with the valve seat each time the movable valve member is closed, a spring being arranged to normally press against a projection eX- against the mow able valve member for movable valve member closed and returning the same to its closed position. Arranged on the movable valve member are a plurality ot blades or wings set at such an angle as to engage the water passing through al central discharge opening whereby the movable `valve member is not only raised away 'from its scat, but is rotated in respect to the seat. whereby when the same reseau; it will engage a different place on the valve seat proper.

A practical embodiment of the invention is represented in the accompanying draw-` ingsl forming a part of this specification, in which similar el'iaraett-zrs of reference indirate corresymndine parts in all the views.

Figure l is a longitudinal vertical section through a pump supplied with a plurality of valves embodying the linvemion, Certain maintaining the' parts of the valves'being shown in section;

Fig. Q is a. vertical longitudinal section through a valve rvembodying the invention; and Fig. 3 ,is a sect-ion through Fig. 2, approximately. on the line 3-3- Referring to by numerals, 1 indicaties the easing-of a pump lformed with -a`discharge pipe ,2. a discharge` chamber 3, and a pair of inlet' chambers 4 and 5, which` receiife the water or other ,Huid rom a supply chamber 6 through valves .7 Vand 8. Valves 9 and 10 are arranged between the chambers' 4. and. and are adapted to permit the water to' 'freely 'fow into the ehamber from the 'chambers 4 and 5, but prevent any reverse movement of the lwater. The chambers *l and 5 are connected by a cylinder 1.1 in which is mounted a pistou 12 connected with a piston rod 1.3. The piston .rod 13 is connected with any suitable source ofpower which reciprocates the piston v12 and alternately draws in waterthrough the valves 7 and 8 from the chambers 4 and 5, and alternately forces it out through valves'9 and into the chamber 3 andfrom thence in a continuous stream out the discharge pipe 2. All ofthe valves are of similar eonstruction.. so that a description of one will equally apply to all. The valve l' (Figs. 2 and 3E) is provided with a valve seat 14 formed with an outlet 15 which is preterably substantially circular although other forms of outlet Could be used. A' substantially spider structure 16 is provided which is formed integral with the valve'seat 1li and which includes an'. internally threaded extension 17. The extension 17 is designed to receive the reduced :threaded end 18 of 'a shaft 19'. The shaft 19 isenlarged atv l2() and defines a shoulder 21 which limits the upward movement. of' the Inova-ble valve member 22. At the upper end the shaft 19 is iormed with an overhanging ledge 23 having an annular depression 24 which accommodates one end of a spring 25. The spring 25 also engages the grooves 26 m. the

blades or wings 27 the accompanying drawings riol othei` 'desiredinate'riaL The Washer 30 is -de signed';-to tightly close the opening 15 -`When fthe', movable `valve member 22 is in its i the val-,vethasl' an v interior and an exterior lowered position, but when raised, as shown in Fig. 2,thewater or other liquid may pass out the opening- -.and `fromthence around the outer--peripheiypf the washer,yor may pass'invvardly and out an openin 31 formed` in 'thefcenterdf-the' movable va ve member 22. .By this Aconstructionand arrangement exit v"from the Vdischarge opening 15.

Ofcoursefthis rotation is de- -signednot to' beg-ofanyvlgreat speedr'as it is intended only'4 .turn the movable' valve` member` sufficiently foricausing the Washer to'seat ata slightly different place Aupon yeach closingof the Valve. In this Way the ywasherI willwear more evenly. and will form a tightejointwith the seat 14 until entirely v Lia-:Worn out.I 2 5 Unless th valve member 22 is rotated th'e Washer 30 would-Wear at certain --places more than at others so that in I'course ofxtiine leakage. would occur long before the Washer was Worn out.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a" valve ofl the class described, a

yalve seat formed with an opening, a mbv viable valve member normally resting on said Valve seat and closing said o ening, said vmovable valve member being ormed with ,an interior openingand a plurality'of in-v elined kWings' arranged in the pathv of move-v ment of iuid passing through said interior Copies of this patent may be obtained for opening whereby said movable valve member isrotated leach time the fluid flows through the valve, and means for reseating the movable valve member. i'

2. In a valve of #the class described, 'a

valve. seat formed with a' discharge openin thereim a` movablevalve member arrange to normally close said seat formed with 'an interior opening whereby the opening in 'said valve seat vhas two Vdischarge openinos,

baiie means connected with said movable valvemember arranged in the path of movementl of the fluid passing through the inte- 'rior discharge opening whereby the movable valve member is rotated when fluid is forced through said valve, and means for reseating said movable valve member. 1

I -3. In a valve of the class described, a seat formed With a discharge opening, a movable valve member formed with an interior opening for providing a path by which Huid said seat may pass around the periphery of said movable valve member and through thev center thereof, a plurality of inclined blades arranged. in the path of movement of the Huid passing through the interior opening wherebysaid mov-able valve member is ro tated upon each iinseating thereof, a spring Anormally pressing against the upper edge -of said movable -valve member, and means for guiding said movable valve memberl and holding said spring to its Work.

4. In a valveY of the class described, a valve seat formed with a discharge opening, a 'rotating laterally movablevalve member arranged to normally close said valve seat, a shaft formed With a bearing portion extending through said movable valve meinber and into said valve seat `whereby said valve seat and said movable valve member are held in proximity, means arranged on said five-cents each, by addressing the Commissioner of Patents; Washington, D.
