Mass,. U.S,A, DESCRIPTION. ' I '111- AiiUimalic Sanding; Apparatus consists of special saml valves A, as shown on page 7, an ordinary air-hrake auxiliary -•- reservoir (I'late V. 21, Fig. 3, Weslinghousc 1S94 Catalogue), anil a small special triple valve (supplied by the Wcstinghouse Air-Iirake Company), more simple in (orm than any triple valve in use for air-brake service, which are locateil at any convenient point upon the locomotive. The triple valve has ihe usual connections with the air-brake train pipe and the auxiliary reservoir; the other connection (which usually leads to the brake cylinder) leads to the sand-box. An additional pipe connection betweei. the auxiliary reservoir and the main train pipe is provided and contains a small plug cock which is located as shown at I in the illustration on page 2. When this cock is open, s> as to establish a limited means of communication between the auxiliary reservoir and train pipe, the track i> automatically sanded only in emergency appli- cations of the air-brake>. When the engineer desires to automatically sand the rails in service stops also, he merely closer this cock. The apparatus for |)neuniatic snnding controlled liy hand, consists of a p, e leading from the main leservoir (jf the air-brake system to the sand valves in tlie sand-lmx. This pipe contains the application valve li, located conveniently in the cab, by which the engineer controls the How of sand for starting trains, ascending grades, etc. It will be ta,uly a,„I a.Uo.a.lcally .an.1.1 in ,l,c„„., effociv. .nnnnor when ,ho nir- l.rak..s aro applici.
