Method of Inserting a New Lubricating- Stick. except when it is displaced by the flange coming in contactwith the rail. The life of the stick varies with the number anddegree of curves on the road. Some sticks having been inservice from 3,000 to 6,000 miles. The chain indicates clearlythe amount of the stick which is used. Inserting a new stick,which takes less than a minutes time, is the only attentionrequired. Fig. 4 shows the different parts of the lubricator. 490 LOCOMOTIVE APPLIANCES.
