This valve is eldapted eb'tltwithi eh eniit lat set teeth the drain pi e to 'efieetitrely shtl't .veehiihuiiieatieh between the gate valve 15 afid lzttfalih-lt po'tts 217 iii'th'e drain ipe 7 I ,Thttetvt is normally: spring rged int clesedpbsitib by cdiled expu' sibn sphin'g 28 ehjciieliii'g the s'tefi betyveeii the valve 22, the t ddwtlwttdiy teem-g shoulder 29 termed in the sleeve 19, With the alve in elbsd pesition, he water can pass fr'e'rii v the beat to discharge through t ttteg valve,

and tie Watei can leak ztioiihd the gat vttl e into the boat. When the boat is rurihihg' at. a sufficiently high SPGGQhQWQVGf, it is desifahle to shift the Vtiljfe 22 Out 0f op'er- I at-ive pesitien; and permiqdminttg of bilge Water th'r'e'ugh the ports 27 and gate valve 15.

To tic'bihplish this fesu'lt there t mttdei in the uppef end Ofth'e difaifi pipe, ih;

' teriia'lsheulder' adttpted'fei eeactioh'with a radially prbj'ectirig pin 31, sdrewt thfeaded,

drive fitted 0r etherwtttqmottnt d in the valve 22. This pin normally works in a vertical groove 32 in the walls of the drain ipeQ By manually grasping a valve stem P handle 33, the valve may be lifted against the action of the spring 28 until the pin 31 clears the upper end of groove 32, at which time rotary movement of the valve stem will shift the pinv 3l to a position where downward movement is blocked by the shoulder 30. For positively locking the valve stem against accidental rotational movement, when in elevated position, I provide a notch or recess 34 in the shoulder 30 at a point diametrically opposite groove 32. WVith the pin seated in this groove as in Fig. 2, vibration of the boat cannot cause accidental rotary movement of the valve,

, and consequently the possibility of the valve accidentally reclosing is eliminated. I

Fig. 4 indloates the pin 31 resting in shoulder at a position. intermediate groove 32 and recess 34. An advantage of the construction is, that in order to reseat the valve,

the pin 31 must be aligned with the groove 32, and will consequently assure reseating of the valve in exactly the same position each time, so that wear upon the rubber element 24 will be minimized.

In operation, when the boat has attained a suflicient speed, theoperator grasps handle i 33, pulls the valve stemnpwardly against the action of the spring, and rotates the latter until the pin 31 drops into the groove 34. lVh'en'it becomes desirable to reclose the valve, the handle is again grasped and lifted to disengage pin 31 from therecess 34:,

and the handle is rotated until the pin aligns with groove 32, whereupon the spring. will.

restore the valveto seated position.

It will be seen-that the device may be readilytaken apart for the replacement of worn parts or for purposes of cleaning.

' The valve and its operating mechanism are essentially quick acting as opposed to .the usual threaded plunger constructions. v

Various changes and alterations might-be made in the general form and arrangement of parts described without departingfrom the invention. Hence I do not wish to limit myself to the details set forth, but shall consider myself at liberty to make such changes and alterations as fairly fall with: ing the spirit and scope of'the appended claims.
