,Thisginvention relates to improvements in I Water discharge valves primarily designed for use in connection iwith dams and the like,' and may be, considered as'an improve-- inent upon the Water dlscharge. valve 'disiclosed in ,myempending' application Serial 7 I Nb; 613,644,. filed.

In this invention as Well as that disclosed in my prior application, the valve consists essentially of valveiseat;imbed'ded irror secured to: adam structure adjacent thefdis charge ze ch of. a outlet/Q1.- tunnel throu h the dam. 'Thegpu'rpose ofth is construction is to allo th t n s it vlem in full-of Water at all me nnd tot p e nt ny ,clisturbancie of fioW, through theti1nnel Whicli is apt, to, cau e ed y curr nt and, par i l. vacuums i l..:t s. qcr i co eat aw y heinteribr of the tunnel. ,In my prior application h re, is a-yoke e u edi oi t ie-v lveus tzl rd ag in Wl iQhQ the Water discharg s when the valve is open; 'This yokehas a tendency to disperse the, w ter' ivhich in certainjinstances is o bjection abl eg An ,o j ct-1 i-th si v ti .i f d piviiei va Wa er i arge ve eisim erti c nst ue.- 'tioni ndi pemt o tto. h d elqs cl i my Prior eppliqa m, t; wh ch w ll not s- 'PQISQ d fle -vth Wa hen t etv lv i invent on, wherein; a

thus opening the valve. Whnthe valve'is larI ineinber,tQ ,1nove, toward; the dam and open, as shown upon Fig. 1, water passes around the pointed closure through the tubular member.

annular body 10 and through the tubular member 21 between the radial webs 28. The stream being thus confined by the tubular member 21 will not become dispersed or scattered, as is the case to a small degree in the device in my co-pending application. The forward edges of the webs 23 which are adjacent the valve seat are preferably sharpened forming knife edges so as to reduce the friction of water passing through the It will be noted that as the valve is in its fully open position, the edge of the tubular member 21 which is most adjacent the body 10 is spaced therefrom.

' This isan important feature of the construction in that it allows air to enter the tubular member with the stream, thus reducing'any tendency of a partial vacuum being formed therein. WVhen a' partial vacuum is formed in a conduit of this kind, it is very destructive in that it quickly corrodes and eats away the metal.

By this construction it will be readily apformed. In order to close the valve the four-way valve 28 is turned, sothat' fluid pressure is admitted between the flange 22 and the head 20, thus moving the'tubular mcmber'and' valve closure from-right to left, causing the valve closure to seat upon the ring 14. Itwill bereadily understood that whilefluid pressure is being admitted between the flange 22 and the head 20, it is being exhausted from the space from between the flange'22 and the head 19. Any leakage between the heads 19 and 20 and the tubular member 21 is effectively prevented by means I of packing 31 compressed by means of glands .poses of repair or inspection.

A further advantage of the above described construction residesin the ease with which the device can be dissociated for pur It will be understood that by loosening the bolts which fasten the heads 19 and 20 in place, these heads can be removed and the tubular member 21 can be removed by unscrewing the nut 26. In this manner the complete operating mechanism can be removed, leaving the valve closure 15 in place. Although the valve closure 15 may fill with water because of'seepage or there may be one or more small holes in the valve closure to allow water to enter it and thus prevent any. tendency to collapse the closure, the water cannot leak timeit will notbe necessary to allow the very easily past the bolt 25. In this main ner the complete device can be overhauled with very little difficulty and at the same proved valve resides in the manner in which it is initially mountedupon the dam or wall. During the construct-ion of. the dam the annular body 10 alone is'embedded in the soft concrete over the outlet or discharge end of the tunnel T. After the concrete has hardbeing withdrawn from within the annular body 10. After this has been done the frame 17 and the tubular member 21 can be applied. By this construction it will be appreciated that workmen in constructing the-dam need only concern themselves with the proper positioning of the annular body 10.

It willbe understood that various changes may be made in the detail of construction without depart-ingfrom the spirit or scope of the invention asdefined by the appended claims. I
