The economy and reliability of every Gasoline Engine depends largely upon a perfect fuel mixture, and upon its being supplied to the engine at the right time, of exact and uniform quality and in just the right quantity.

All this is of course difficult to accomplish, but how well we do this, the reader can judge from the following description and conventional cuts Figs. 1 and 2.

In Fig. I, Z indicates pipe connection to generate valve X. Check valve H is closed until opened by a suction stroke of engine whereupon gasoline it drawn into valve X in a fine stream through small opening shown and meeting the rush of air as it is drawn through the generator, is thoroughly vaporized and mixed with the air and the mixture passing on into another chamber (conventionally shown at D) is met and mixed with enough additional air, drawn in through passage J and K and valve L to form a mixture of maximum strength and then is led by passage I and B through inlet valve F (also automatically opened by engine suction) into the compression space of the Engine. At the end of suction stroke valves F and H close automatically, the valve H shutting off all further flow of gasoline, thus preventing waste. The mixture in the engine is then compressed and fired at the right time, and after doing its work on the expansion stroke is discharged through exhaust valve G (Figs. 1 and 2) which is automatically opened at the right time by means of arm 2 which is operated by cam 4 on side shaft 5. The upward movement of arm 2 while opening exhaust valve G, at the same time pushes side rod 10 upward, locking inlet valve F tightly against its seat (as in Fig. 2), thus effectually and by very simple means preventing the engine from stealing small quantities of gas, in case the exhaust valve is held open by action of the governor during next suction stroke because of engine being up to speed. At the same time the upward movement of the side rod 10 moves out of contact at R with flat spring T, thus breaking the electric circuit, increasing the life of the battery and using current again only as required to ignite a charge of gas.

To prevent excessive overheating, the valve body is water jacketed as shown at E, and the cylinder is water jacketed as shown at 6.


The complaint that Gasoline Engines will not work as well, or develop their rated power in cold winter weather as in warm, is so frequently heard and so generally accepted as a discouraging fact that the prospective purchaser will do well to bear in mind our claims to have overcome this serious difficulty.

Our mixing device and valve attachment, as shown in Fig. I and Fig. 2, are constructed upon the correct principle of securing a perfect mixture of gasoline and air under all conditions of temperature.

This means a great deal, inasmuch as it guarantees the successful operation of the Badger Engine in zero weather, as well as the full development of its rated power.

We make no empty claims but proceed to explain the reason why.

Observe sketch Fig. 2 showing exhaust valve G open, discharging burnt gases, as these hot gases pass out through this valve at the end of each successive explosion, they tend to thoroughly warm up the entire valve attachment.

The advantages of this are apparent. In zero weather the icy cold mixture of gasoline and air is drawn through the warm mixing chamber, passing through the inlet valve F, as shown in Fig. I, becomes warm and dry enters the cylinder or explosion chamber in a perfect state of mixture and when fired the explosion will be clean and powerful, there will be no loss of fuel or power as the combustion is perfect.

Furthermore this method of drawing the cold mixture over the hot exhaust valve tends to keep this valve at a proper temperature, not allowing it to become heated to such a degree that it will corrode and warp, resulting in a leaky valve as is the case with other engines on the market continuously discharging hot exhaust through this valve without any counteracting cooling influence as in our method.

It is evident to the reader that by our system of securing a perfect mixture under all conditions of temperature, we do not experience any difficulty in successfully operating our engines in the coldest weather.

Read the testimonials, then buy a Badger and be convinced.
