Show OIL PUMP FIXED ON ! AUTOMOBILE ENGINE Prevents Clogging and Burned-Out Burned-Out Bearings. Illustration Shows Plan for Arranging Force-Feed Oiling System at Small Expense Operated by One of the Cams. On an automobile engine which was oiled by the "splash" system, it was found that the. tube which conducted the oil from the flywheel to the front part of the engine became clogged, and some burned-out bearings resulted. result-ed. To prevent the recurrence of this accident, a pump was installed in the oil line and connected to be driven hy the cam shaft, as shown in the sketch. The upper part of the motor crank case, on the camshaft side, was drilled out and lapped opposite one of the cams,-to take a brass tube, which was' threaded with a standai! pipe thread. This tube was reamed out to a snug fit for a small piece of shafting, which formed the plunger of tlie pump. Another An-other piece of tubing was screwed onto the first at right angles, and to the ends of it, through two ball-check valves, were attached the oil tubes leading to the crank case and to tlie hearings of the engine. These check valves acted to prevent oil from flowing flow-ing back to the crank case, while permitting per-mitting it to flow in the' proper direction. direc-tion.

In this way the engine was provided pro-vided with a force-feed oiling system at small expense. G. A. Luers, Washington, Wash-ington, in - Popular Mechanics Magazine. |
