UNITED STATES HENRY BRIGGS, OF HASBROUCK HEIGHTS, NEW JERSEY.

MPLOSIVE MOTOR.

Application led February 13, 1922. Serial No. 536,080.

To all whom it may concern:

Be it known that I, HENRY Barcos, a citizen of the United States, and a resident of Hasbrouck Heights, in the county of Bergen I and State of New Jersey, have invented a new and Improved Explosive Motor, of which the following is a full, clear, and exact description.

The present invention relates to new and useful improvements in motors, and it pertains more articularly to motors of the internal com ustion type.

It is one of the primary objects of the present invention to construct a motor in such a manner that the piston of the motor will hold its position at top dead center until the crank of the crank shaft has passed over the top dead center point.

It is a further object of the invention to so construct the motor that the cylinder will be offset with respect to the crank in order that the force of the explosion will be transmitted to the crank in a true perpendicular line.

It is a further object of the invention to so construct the motor that during the last stages of compression of the charge within the cylinder, the resistance offered to the crank shaft instead of gradually increasing $0 will gradually decrease, thus requiring less power to compress the charge than is necessary in internal combustion motors of the common type.

With the above and other objects in view,

' reference is had to the accompanying drawings, in whichA Figure 1 is a vertical sectional view of a motor constructed inv accordance with lthe present invention;

Fig. 2 is a diagrammatic view showing the position of the several parts at. the beginning of the compression stroke of the motor;

`Fig. 3 is a similar view showing the piston of the motor approaching top dead center;

Fig. i is a similar view showing the piston and crank of the motor at top dead center;

Fig. 5 is a similar view showing the piston at top dead center, the crank having passed over top dead center, said figure showing the position of the. several parts at the time the charge under compression is tired and the piston starts its power stroke.

Referring to the drawings and more particularly to Fig. 1, the reference character designates the motor cylinder, and said motor cylinder is divided into an upper chamber 11 and a lower chamber 12. The upper chamber 11 is provided with an exhaust port 13 and an intake port 14, said intake port communicating with the lower chamber 12 by means of a by-pass 15 in which is mounted a check valve 16 of any desired type. Leading into the by-pass is a fuel supply pipe 17, and mounted in said fuel supply pipe 17 is a check valve 18.

The reference character 19 designates the piston and connected thereto as at 20, is a piston rod 21. The piston rod has rigidly secured to its lower end a block 22 and said block 22 is provided with a. cam slot 23. To provide for slidably mounting the block Q2 the crank case 24 of the motor is provided with guideways 25 in which the block 22 is slidably mounted as indicated by the reference character 26.

The reference character 27 designates the crank shaft and 28 designates the crank thereof. This crank Q8 carries a pin 29 and pivotally mounted on said pin Q9 is a block 30. The block 30 is substantially elliptical in shape and is adapted to travel through the cam slot 23 oi the block 22. The cam slot 23 in the block 22 is provided with a curved portion 31 running into a curved portion 32 which terminates in a shoulder 32 from which the wall 33 extends downwardly in approximately a straight line to the end 34 of the slot. This curved portion 32 is concentric with the path of travel of the crank of the crank shaft, which permits of travel of the crank without aiiecting movement of the piston. Opposite to the wall 33 the wall 35 ot the cam slot is straight in parallelism to the wall 33 thereof, and from a point 36 approximately opposite the shoulder 32 the wall is curved as indicated by the reference character 37 to the opposite end 38 of the slot Q3.

The device functions in the following manner: e.

uring the operation of the motor when the several parts are in the position shown in Fig. 2, the explosive charge enters the cylinder 11 by means oit the port 1l and the bypass l5, said charge having been forced from the lower chamber 12 or" the cylinder lO upon the down stroke ot the piston 19. is the crank travels in the direction of the arrow A in Fig. 2, the piston will be moved in the direction of the arrow B or inwardly of the cylinder 10 to the position shown in Fig. 3. In this position the piston 19 has approximately reached the height of the compression stroke and the block 30 is beginning to ride the curved surface 31 of the cam slot 23. Owing to the curve of the portion 31 of the cam slot 23, the minimum resistance is offered to the crank shaft 27 during the last stages of the compression stroke. Upon this up stroke of the piston a fresh charge isdrawn in through the fuel supply pipe 17 and the by-pass 15 to the lower chamber 12 of the cylinder in order that said charge may be passed through the by-pass 15 upon the next power stroke of the piston to the chamber 11.

After the piston 19 reaches the height of compression stroke, in which position it is shown in Fig. et, the crank 28 is at top dead center and the block 30 is riding the curved wall 32 of the cam slot 23. With the parts in this position the block 30 rides through the cam slot 23 maintaining the piston 19 in the compression position until suchv time as the block 30 passes over the shoulder 32 of the cam slot 23, which shoulder may be any desired degree of the downward stroke of the crank on the right ascension and in which position the several parts are shown in Fig. 5. As the parts reach this position the charge in the cylinder is tired by a suitable ignition device 40 'and the force of said explosion is transmitted by means of the piston rod 21 to the crank shaft 27 through the medium of the -pin 29 and the, sliding block 30. Since this explosion takes place at the time the block 30 leaves the concentric portion 32 and yenters the straight portion 33 of the cam slot, the force of energy is received by the block riding from the thin edge of the wedge to the thick end of the Wedge, thus increasing the speed of the crank over the speed of the piiston on the pistons downward strokes.

y such a construction it is apparent that the crank travels faster than the piston and this gives greater impetus to said crank.

As the piston travels downwardly on the power stroke, the charge previously taken in to the lower chamber 12 of cylinder 10 is forced by way of the by-pass to the upper chamber 11 ofthe cylinder 10 and the products of combustion are exhausted through the pipe 13, the incoming fresh charge serving to aid in the exhaust of the products of combustion by a displacement thereof common to this type of motor.

From the foregoing construction it is apparent that the present invention provides a new and iiiipioved i'oiin of internal coinvbustion engine in which the explosive charge power at a position when greater leverage of the crank is had, thus increasing the power of the motor due to the leverage position of the crank at the time of tiring of the explosive charge. Furthermore, by the construction shown which permits of a dwelling of the piston at the point of top dead center or full compression osition, the compression of the explosive c arge is maintained at full compression during the time of tiring.

It will also be apparent that owing to the curvature of the wall 31 of the cam slot 23 at that time when the greatestl resistance is offered by the compression of the explosive charge within the cylinder, i. e., n-ear the end of the compression stroke, the resistance transmitted to the crank shaft will be materially reduced owing to the fact that the block 36 is riding this curve in such a manneras to produce a relatively slow movement of the piston in the compression direction, said block riding lfrom the thick edge of the wedge cam to the thin edge thereof. Furthermore, by'arranging the cylinder offset with respect to the crank case, it will be seen that at the time of firing the explosive charge, the crank will be directly over the longitudinal center of the piston and will thus remove side thrusts due to the angular disposition of the piston and crank in the common type of motor.
