DOUBLE CONNECTION LUBRICATOR. not only in prolonging the life of the engine, but inreducing friction, and thus increasing types of lubricators have been devised forintroducing oil into the valve chest and cylinder, butprobably the most reliable and easily managed appa-ratus for this purpose is a good oil pump worked bythe engine itself, for the reason that it is positive andthe flow of oil is not easily affected by changes in 278 ENGINEERING temperature. In the case of large horizontal enginesespecially, it is good practice to introduce a littlegraphite along with the cylinder oil once or twice aday. In many cases trouble is experienced with the bot-. f^s* FIGURE 94. torn guides of horizontal engines, especially if theengine runs over, as illustrated by Figs. 94 and 95,where it will be seen that in addition to the weight ofthe crosshead, the thrust or pressure consequent uponthe pull, Fig. 94, and push, Fig, 95, also comes uponthe bottom guide both with the inward and outward
