GAS-ENGINE.

Specification of Letters Patent.

Patented Oct. 18, ii: to

Application filed June 2, 1909. Serial No. 439,703.

To all whom it may concern:

Be it known that I, JOHN M. Knorsii, a citizen of the United States, residing at Stockton, in the county of San Joaquin, State of California, have invented certain new and useful Improvements in Gas-Engines; and'I do declare the following to be a full, clear, and exact description of the same, such as will enable others sk lled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in motors generally and'particularly to gas e11- gines of that type known as four cycle motors, the main object of the invention being to avoid and do away with the obnoxious and annoying smoke and odor which is now so commonly prevalent around motors of this type especially with marine motors where the boat is liable to be inclosed which gives the smoke and smell no opportunity to escape to the atmosphere.

A further object of the invention is to produce a simple and inexpensive and easily operated and yet an exceedingly effective device for the purpose.

These objects I accomplish by means of a tightly inclosed crank case on the engine, the same having an air inlet port of suitable dimensions to freely feed a suflicient quantity of air by the suction of the engine into the air pipe of the carburetor of the engine, the air being taken from said crank case through a pipe extending to a point near the roof of such case to maintain the air free from oil or dirt, the air thus passing from the atmosphere through the crank case and thence to the engine picking up and carrying with it all the smoke and odor of heated oil which always emanates from the crank case of an engine, thus preventing the same from circulating through the atmosphere and becoming obnoxious. A further advantageous feature of the air passing through the crank case is that it becomes heated which, of course, is a great aid to a rapid and effective mixture. I also employ such other and further structure and relative arrangement of parts as will more fully appear by a perusal. of the following specification and claims.

I11 the drawings similar characters of ref erence indicate coresponding parts in the several views.

Figure 1 is a front elevation of my improved motor. Fig. 2 is a rear elevation of the same. Fig. 3 is a sectional view of the crank case showing the air outlet feed pipe mechanism. I 4

Referring now more particularly to the characters of referenceon the drawings 1 designates the engine proper having a crank case 2 which crank case is entirely inclosed on all sides and provided with an air inlet port 3 from the top of one side of said casing.-

4 is an outlet air supply pipe starting from a point a near the roof of the casing 2 at a side opposite to the intake port 3 and pro vided with a flanged open cap 5 at its top, such pipe 4 extending outside the casing 2 and connecting with the air pipe 7 of the carburetor of the cngme.

In practice the suction of the engine draws air into the case 2 through the inlet port 3, circulates it through said casing 2 and thence draws it through the pipes 5 and 7 into the carburetor 8 and thence to the engine cylin ders, such air carrying with it through to said engine the odor and smoke from the crank case and thus ridding the immediate surroundings of the engine of the same. The flange 6 of the cap 5 prevents the crank of the engine throwing any oil or dirt into the pipe 4, since said flange 6 extends closely against the roof of the casing, the open space a forming a free passage way for the air.

In addition to the advantages gained as set forth above, a further advantage of passing the air through the crank case rior to its entrance to the cylinders is that in passing through the crank case, the suction of the air into the cylinders causes it to gather -or pick up a more or less quantity of lubricant and this passes to the cylinders thus aidmg in lubricating them.

From the foregoing description it will be readily seen that I have produced sucl" a means for disposing of the smoke and smell 'of a gas motor as substantially fulfils the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is t 1. A gas motor comprising an engine having an inclosed crank case, an open air inlet into said crank case, an open outlet pipe proj eating from said crank case to the cylinders of the engine, and an open flanged cap on said pipe.

2. A gas engine comprising an engine having an inclosed crank case, an air inlet into such crank case, a vertical pipe disposed from the top to the bottom of said crank case, the upper end of said pipe being open, and means communicating from the bottom of said pipe with the cylinders of saidengine. I

3. A gas engine comprising an engine having an inclosed crank case, an air inlet into said crank case,'a vertical pipe within said crank case extending from the top to the bottom thereof,an 0 en flanged cap on the top of said pipe an means communieating from the bottom of said pipe with the cylinders of said engine.

In testimony whereof I aflix my signature in presence oftwo Witnesses.
