BY PAUL R. DUFFEY A new style of locomotive water gage cock, which is the in-vention of Harry Glenns, Portsmouth, Ohio, is shown in one ofthe illustrations. In designing this cock it was desired to obtainone that would meet the rigid requirements of the InterstateCommerce Commission and permit the user easy access in mak-ing repairs while the locomotive is under steam. It will beseen that the device is made in such a manner that the valvemay be easily removed and replaced in case of necessity. Todo this the stem and cap are first removed, when the valve maybe taken from the body, the passage from the boiler being closed!. Glenn Gage Cock by the ball valve. In regrinding while the boiler is under pres-sure, the tail piece, which holds the ball valve from its seat, isremoved. The valve is then reground on its seat by means of aspecial socket made for that purpose. The ball valve preventsthe escape of steam from the boiler during this operation. Ifthe gage cock is used frequently no trouble is experienced fromthe ball valve becoming covered with scale. Another simple design of water gage cock is also is simple in construction as well as efficient from a servicepoint and meets the requirements of the Interstate CommerceCommission. The possibilities of leaks are much less than inmany of the types now in use. The valve consists of the handle,the spindle, the packing nut, the removable section of the body, || ,H ^^^^^^3.,^^::^^^^:^^^^^ -^-^^r?^^^^?^^^;^;^^^.^^
