INTERNAL-COMBUSTION ENGINE.

Specification of Letters Patent.

Patented June 9, 1914.

Application led April 10, 1913. Serial No. 760,131.

T0 all whom t maj/,Concern Be it known that I, CHARLES SYxoRA, citizen of the United States, residin at Storden, in the county of Cottonwoo and State of Minnesota, have invented new and useful Improvements in Internal-Combustion Engines, of which the following is a specification.

My present invention pertains to internal combustion engines, and contemplates the provision of improved means for heating the explosive mixture employed precedent to the passage of such mixture into the explosion chamber of the engine.

The invention will be fully understood from the following description and claim when the same are read in connection with the drawings, accompanying and forming part of this specification, in which the tigure is a View, partly in side elevation and partly in section. of so much of an internal combustion engine and its appertenances as is necessary to illustrate the preferred embodiment of my invention.

Referring by numeral to the said drawing: 1 is the explosion chamber of an interna-l combustion engine. 2- is the exhaust pipe for products of explosion, and 3 is a carbureter, connected through a manifold 4 with the interior of the combustion cham'- ber. All of these elements are preferably of the conventional type, though they may be of any other construction compatible with the purpose of my invention without involving departure from the scope of the same as claimed.

In furtherance of my invention, I rovide a jacket 5 around the manifold 4. T e said jacket is provided with adischarge pipe 6, and is connected at 7 with the interior of the exhaust pipe 2, whereby when the engine is in operation a part of the products of combustion will pass to and through `the jacket and will circulate about the manifold 4 so as to heat the explosive mixture while the same is en route to the explosion chamber. From this it follows that during the coldest weather the explosive mixture suplied to the explosion chamber will be preheated, and hence the engine will operate to the best advantage.

In the conduit 7 intermediate the exhaust pipe 2 and the jacket 5 is arranged a valve 8, preferably of damper form as shown,

through the medium of which an operator can regulate the supply of the heated products of Ycombustion to the jacket 5, as occasion demands.

For the purpose of initially heating thev manifold 4 and assuring prompt starting of the engine in cold Weather, I dish or make the lower end of the jacket 5 cup-shaped, as indicated by 9, and I also provide the jacket 5 with an opening 10, normally closed by a door 1l. Through the said opening 10 gasolene or other suitable hydrocarbon is introduced to the cup 9, and when said hydrocarbon is ignited, the manifold will be adequately heated until the operation of the engine is established and the manifold is maintained in a heated state by the heated products of combustion from the exhaust pipe 2. It will be noticed in this connection that the discharge pipe 6 is located above the cup 9. and that therefore there is no liability of the exhaust displacing the hydrocarbon during the burning of the latter in the cup.

It will be gathered from the foregoing that my improvement is compact, simple and inexpensive, and yet are calculated to contribute materially to the efficiency of an internal combustion engine. I would also have it understood that because of my improvements kerosene as well as gasolenc may be employed as fuel in the engine.

Having described my invention, what l claim and desire to secure by Letters-Patent, is:

The combination in an internal combustion engine, of an explosion chamber, a carbureter, an upright pipe connected with the explosion chamber and thecarbureter, an upright jacket surrounding said upright pipe and having a dished or cup-,shaped bottom and a lateral discharge pipe arranged above the same and also having a door-controlled opening in its side and above said bottom, and a conduit intermediate the exhaust port of the explosion chamber and the jacket.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
