The amount of oildischarged may be regulated by interchangeable nipples inthe bottom of the lubricator, as these nipples are constructedwith cylinders of various depths whereby any size may bereplaced by another of the desired capacitv. The construction of the lubricator is simple, with few-parts to get out of order. While the four-feed type is Illus-trated, the six-feed type is recommended for Atlantic orPacific locomotives,

While the four-feed type is Illus-trated, the six-feed type is recommended for Atlantic orPacific locomotives, for oiling the truck wheels also. Two forms of air valve are illustrated in Fig. 2. Thelever controlled air valve shown at the left is adapted forswitch engines. It may be installed in the air supply pipesin any convenient place near the back of the engine wherea connecting rod may be extended from its lever to theframe of the locomotive tender. By this means it is actuatedby the relative swing between the engine and the tender. Device for Distributing Oil to the Flange when the locomotive is entering a curve, and oil is suppliedto the flanges on curves only. The valve control mechanismis so constructed that when the lever is moved either waythe valve opens for an instant and automatically closes whena pressure of 50 lb. is attained in the air cylinders of thelubricator. The gear controlled air valve, shown at the right in Fig. 2,is generally adopted for locomotives in road service. Itmay be installed in the air supply pipes in any convenientplace where a coil spring belt may be operated over thesheave of the valve and the axle of the locomotive. Bythis means it is actuated at regular distances traveled, andoil is supplied to the flanges at regular intervals. The valveis opened by the gear, but automatically closes when a pres-sure of 50 lb. has been obtained in the air cylinders. Proper oil distribution is most essential to successful flangelubrication and the distributor shoe
