JARED V. BROWN, JRN, 0F VJAXMACI-IIE, TEXAS.

INTERNAL-GOMBUSTIGN MOTOR.

To all whom it may concern Be it known that I, JARED V. BROWN, Jr., a citizen of the United States, residing at Waxahachie, in the county of Ellis, State of Texas, have invented certain new and useful Improvements in Internal-Combustion Motors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to internal combustion motors.

The object of the invention resides in the provision of an internal combustion motor which may be composed of any number of cylinders and in which an explosion is effected at one or the other end of each piston at the termination of each stroke of the piston.

A further object of the invention resides in the provision of an internal combustion motor which embodies an improved construction of cylinders and connections between the pistons and the crank shaft.

A still further object of the invention resides in the provision. of an internal combustion motor of the character specified which will be simple, light, composed of comparatively few parts and capable of generating great power.

lVith the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in which Figure 1 is a side elevation of a two-cylinder internal combustion motor constructed in accordance with the invention and showing certain parts in section, and Fig. 2, a vertical longitudinal section of the motor.

Referring to the drawings the motor is shown as comprising a base A which embodies a central dished portion 10 and terminal bearing portions 11 and 12, said central dished portion 10 serving to allow the proper movement of the crank shaft which is indicated at 13. The body of the motor comprises cylinders B and C which are cast integral with a connecting web 14 and also Specification of Letters Patent.

Application filed August 8, 1913.

Patented May 26, 1914.

Serial No. 783,743.

with hearing portions 15 and 16 which cooperate respectively with the bearing portions 11 and 12of the base A to form suitable journal bearings for the crank shaft 18. Journaled on the cylinders B and C is a cam shaft 17 which is operated through the medium of suitable connections 18 with the crank shaft 13. The rotation of this cam shaft 17 operates valves 18 to control the supply and exhaust to and from the cylinders B and C in the usual and well known manner. Each of the cylinders B and C embodies a removable crown or top portion 19 whereby access to the interior of the cylinder may be readily had and such structure also being convenient in effecting the boring of the cylinders in the first instance. The cylinder B is provided on its inner side with a vertical slot 20, while the cylinder C is provided on its inner side with a corresponding vertical slot 21.

Slidably mounted in the cylinder B is a piston 22 provided with the usual packing rings 23. Secured to this piston 22 is a transverse pin 24 one end of which projects through the slot 20 and has pivoted thereto one end of a connecting rod 25 while the other end of said rod is connected to the crank shaft 13 in the usual manner. The pin 24 is extended beyond the connecting rod 25 and provided with a squared portion 26 which is guided in a vertical guide way 27 formed in the web 14. Slidably mounted in the cylinder C is a piston 28 which has mounted therein a transverse pin 29 corresponding to the pin 24, said pin 29 extend ing through the slot 21 and having pivoted thereto the upper end of a connecting rod 30, the lower end of said connecting rod 30 being secured to the crank shaft 13 in the usual manner. The pin 29 is extended be yond the connecting rod 30 and provided with a squared portion 31 which is movable in a guide way 32 formed in the web 14, said guide way 32 being similar to the guide way 27.

Any suitable ignition system may be employed in connection with the motor previously described but as same forms no part of the invention illustration and description thereof is omitted in this instance.

While the motor has been illustrated and described as of the two-cylinder type it will be obvious that any number of cylinders may be employed in its construction without departing from the scope of the invention.
