Show SURE-AUYiNU rnimLif SAVES AUTO BATTERY Device Causes Engine to Start Firing at Once. Means Found for Injecting Into CyL inders Sufficient Amount of Gasoline Gaso-line to Vaporize and Mix With Air. Many automobiles require a sure-acting sure-acting priming device to cause the engine en-gine to start firing at once, instead ol compelling the starting motor to whli for long periods, which puts a hsnvy drain on the storage battery. Therefore, There-fore, some means must be found of Injecting In-jecting Into the cylinders a sufficient amount of gasoline so that enough will vaporize and mix with the air In the combustion chamber to form an lgnita-ble lgnita-ble mixture. The best of these Is one that can be operated from the driver's seat Obtain an ordinary sight-feed oil cup, as shown In the illustration. Attach At-tach it to a suitable part of the car, such as the dash, or mount it on the engine block, above the carburetor. Bj the use of one-elghth-lnch copper pipe, like that for the gasoline line, the cup should be connected with the Intake In-take manifold directly above the vertical ver-tical tube to the carburetor. Then, by the adjustment of the feed-valve on the cup, the correct amount of gasoline gaso-line is admitted to the manifold In the right place. In this way all cylinders will receive the same mixture, and of course will develop maximum power. After the engine has started well, the feed-valve cup can be closed. This method Is far more relluble than prim- jSf CLASS COPPIg HJttrtQ jgf OIL CUP IWttrOLD Save your storage battery by equipping equip-ping your car with this simple sure-acting sure-acting primer. ing-cups on cylinders, for, when the engine is primed through them, a greater quantity is Injected than is needed for one explosion, and for this reason there is a certain amount of vapor formed, regardless of low temperature, tem-perature, which then finds its way past the piston-rings Into the crankcase and mixes with the oil.
