I have gotten the emergencyapplication on cars where the anglecock was only half open. But. ofcourse, all cocks should be wide open:but would not the better plan be to takeadditional pains when making up thetrain and see that the cocks are all RaStpaf i LveuminU* Emginm, iitg PROPOSED SLACK ADJUSTER .\RRANGEMEXT FOR PASSENGER BRAKE. The Silvene Retaining and ReleaseValve. The purpose of the present invention isthe provision of a relief valve for the aircylinders of automatic brake mechanism,which will be self-acting and quickly re- pipe, the smaller piston closing two pas-sages, the one leading to the brake cylin-der, the other to the outer air. The improvement consists essentially ofthe novel features and the combination ofthe parts which hereinafter will be more 474 RAILWAY AND LOCOMOTIVE ENGINEERING Xii\ ember. 1902. fully described and claimed and which are lower portion of the part 3 and coinnni- shown in the annexed drawing, which is a nicatos with an annular chamber, 9.
