The ordinary method of draining the engine bed and pansis to drill and tap a small opening with which the drip iiipesare connected from below. Some engine beds have drainscarried to one side, jjossibly half in and half out of the floor,the details employed being insufficient to provide for theproper flow of the oil and likely to become damaged. Thedrip pot shown in Figure 347 (R2-fi) should be provided, there.

Modern practice retjuires but little piping for cylinderlubricators other than that furnished with the engine. Forcefeed lubricators are used almost exclusively. They are eco-nomic and positive in operation. There is chance tor con-siderable loss due to careless use of cylinder oil when it issupplied from a i)ipe line. When the drop, sight feed lubri-cator was extensively used, there were various methods ofpiping the lubricators, as shown in Figures .04 to 57. Forlarge power plants the cylinder oil supply system, shown inFigure 58, may be found convenient and clean. The savingin oil and labor will be slight, but as the piping for such asystem is inexpensive, it may, in an indirect way, be a profit-able investment, as it aids in securing cleanliness in the plant.
