permitting. the

stem'38 from which rojects an arm 39, and this arm is connected to a rod 40 by means of a link 41. The rod 40 is. connected to a plunger 42 arranged within a cylinder '43 that communicates withthe storage reservoir 15, and the end of the plun er is constantly exposed to the pressure of uid in the reservoir. Around the rod 40 is coiled a spring 48 that tends normally to force the p unger or piston inward against the ressure of the gases. Projectin from the p unger is a pointer 49 that extends through a suitable slot formed in the cylinder 43 and may move over graduations for the purpose of indicatingthe pressure in the reservoir. 7 hen the pressure is abnormallyhigh, the plunger 42 is moved-outward, and this movement is transmitted through the previously described connections to the valve 36, turning the latter to present a port of smaller area into feed position, and the greater the pressure, the smaller .the port, or if the pressure is exceedingly high, the valve may be moved to closed position. In this manner the quality of the explosive compound is governed in accordance with the degree of pressure contained within the reservoir.

Projecting from one end of the valve 24 is a stem 40 carryin an arm 41 which may be connected by am 42 to the stem of plun er 26, and mounted also on the stem 40 is a c etent disk 48 havin a tooth 49 that is arranged to be engage by a pawl 50 pivoted on the'frame and moved by a spring 51 in the direction of the disk, so that the pawl will moveinto engagement with the tooth 49. When, therefore, the plunger 26 is moved outward, the movement is transmitted through the connections to the valve 24, and the latter will be turned until its )Oll) is in vertical position in alinement wit the oil feed pipe 33 and the ort will be filled with oil, asolene or the li e. Connected to the paw 50 is an arm 53 that is arranged in the path of movement of a lug 54 rojectin from the face of the rod 42, and w en the p unger has nearly completed its stroke, the lug 42" will engage the arm 53 and will move the pawl from engagement with the tooth 49' inorder to permit the return of the valve 23 to such position as to place its port in communication with the pump cylinder, and the passage Way 22. To accomplish this latter movement the stem of the valve is connect-ed at one end to a spring 58, said spring being suitably set-ured to a fixed point and being placed under stress during the outwardmovement. of the plunger, so that as soon as the pawl 50 is released, the spring is free to contract and move the valve 23 to a position to effect discharge of the contents of the port into the ex losion chamber.

Duringt e in stroke of the plun er 26 the air previously drawn into the cylin er is compressed, and during the latter portion of the stroke, the valve is moved to the. 0 en position, so that the compressed air striki the hydro-carbon will force the latter through into the explosion chamber and form an explosive compound which is ignited after passmg into said chamber. The ignition is accomplished at the proper time by theengagement of theend of arm 60 of the rod 42 with the movable arm 61 of a sparking plug 62 so that the circuit will be broken for-the purpose of creating a spark and firing the cha e. a

This charge instantly passes beyond t e valve 21 into ,the storage reservoir. At suitable points onthe frame are bearingsfor the support of a shaft that is provided with a crank 81 connected by rod 28 to the lunger26.

The exhaust gases pass throng the pipe 90 to a vertically disposed flue 104 that extends upward from a casing 105 surrounding the explosion chamber, and as this flue is heated by the exhaust gases, an upward draft is created which wil draw in the cool outer air, so that a circulation may be main-' working space of the engine, owing to the fact that in the latter case the operation is 'intermittent and exerts considerable strain on the working parts, while the use of a continuous volume of' gas of practically uniform pressure permits smooth runningof the engine at uniform speed.
