ADOLF SPIEL, OF BERLIN, GERMANY.

PETROLEUM-ENGINE.

SPECIFICATION forming part of Letters Patent No. 393,127, dated November 20, 1888.

Application filed May 13, 1887. Serial No. 238,152. (No model.)

To all whom it may concern.-

Be it known that I, ADOLF SPIEL, of Berlin, Germany, have invented a new and Improved Petroleum-Engine, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved petroleum-engine in which the explosion of a mixture of petroleum and air forms the motive power.

The invention consists in the construction and arrangement of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, 1n which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my improvement with parts in section. Fig. 2 is a plan view of the same with the cylinder and its connectlons in section. Fig. 3 is an enlarged end view of the cylinder end. Fig. 4 is a diagram illustrating the motion of the cylinder-piston and oil-pump piston. Fig. 5 is a longitudinal sectional elevation of the engine a governor.

Fig. 6 is an enlarged sectional plan view of the cylinder end on the line 3 y of Fig. 3. Fig. 7 1s a longitudinal sectional elevation of the cylinder; and Fig. 8 is a vertical cross-section ofthe same on the line am of Figs. 1 and 7.

My improvement is mounted on a suitablyconstructed frame supporting the cylinder A, which is open at its inner end, and is provided with the usual piston-head, driving-shaft, and intermediate connections. The outer end of the cylinder is closed by a head, B, provided with the inwardly-opening valve 9, which admits a mixture of air and petroleum into the cylinder from the channel 9, formed in the said cylinder-head B. The channel g is connected with the air-inlet pipe h, and into this channel 9 opens the end a of the oil-supply pipe (1, connected with an oscillating oil-chamber pivoted with its cylinder (1 at e to a bracket of the main frame.

The piston-rod d of the cylinder d is provided with the head 0, having a slot, 0, into which projects the crank-pin-f, secured to the disk m, secured to the shaft 12, carrying the bevel gear or friction wheel I), meshing into a similar wheel, 6 secured to the main drivingshaft. The gear-wheels b and I) have a proportion of one to two, so that each revolution of the main shaft imparts one half-revolution to the said shaft 6.

In the piston-rod head 0 screws the screw 1', extending with its lower end into the slot 0 and serving to regulate the stroke of the oilpump. The latter is connected by the pipe at with the oil-reservoir or, located in the hollow lower part of the frame carrying the engine.

The pipe a is provided with a valve, 17, operated from the governor Z, so as to regulate the supply of oil according to the speed of the engine, thus increasing or diminishing the speed of said engine. The valve t is provided with a valve-rod, k, pointed at its lower end and adapted to regulate the flow of oil in the pipe 66*, on being moved up or down, by the action of the governor Z, which may be of any approved construction. The rod It is held at its lower end in the pipe is, which is secured to the valve 2', and extends above the level of the oil-reservoir m, so that no stuffing boxes are required on the said valvei for the said rod 70.

The disk m, secured on the shaft b, is provided on its rim with a cam, m, adapted to operate the valve 1%, fitted in the head B, and serving to establish a communication between the outlet ofthe cylinder A and the ignitingchamber 1) by means of the channel 0, which is opened and closed by said valve n. The outward motion of said valve n is limited by the stop it, and a yielding connection is made with the cam m by the bolt it, held against said cam m by a spring, n held in said valve n. This spring also forces the valve 42 upon its seat in the channel 0. In the igniting-chamber 19 is held a light or lamp, of any suitable construction, for igniting the charge of gas and oil,in a manner hereinafter more fully eX- plained. In the outer end of the cylinder A is formed a sidewardly-extending channel, q, in which is held a valve, q, opening outward and serving as an exit for the products of combustion.

The operation is as follows: The piston in the cylinderAwhen traveling forward sucks in air through the air-pipe h, and at the same time the oilchamber forces a quantity of oil through the end a of the pipe a into the channel 9, so that a complete mixture of the air and the oil takes place, and this mixture passes into the cylinder through the valve g,which is opened by the suction of the forward movement of the piston. On the return-stroke of the piston the valve 9 is closed and the mixture in the cylinder is compressed, as this mixture cannot escape through the channel 0, which is held closed by the valve a, pressed inward by the action of the cam m of the disk m, secured to the shaft b. When the piston is near the end of its stroke, then the cam m releases the bolt it, thus freeing the valve 12, which is forced outward against the stop n by the pressure of the compressed mixture in the cylinder, part of which mixture now passes into the ignitingtube 19 and is ignited by the light or lamp therein, thus igniting the entire charge in the outer end of the cylinder, and thus causing an explosion, the force of which propels the piston forward and imparts motion to the main driving-shaft. On the return-stroke of the piston the valve n is again seated on the channel 0, and the products of combustion are forced outward into the channel q and through the valve q to the outside. The oil-pump draws oil from the reservoir x at the last return movement of the piston and again forces the oil into the channel g on the forward motion of the piston, as above described. Thus it will be seen that the piston makes two complete strokes to one movement of the oil-pump. .Vhen the engine exceeds its normal speed, then the balls of the governor Z cause the rod is to move downward, thereby either entirely closing the opening 1'' or closing it partly only, so as to admit no or little oil from the oil receptacle 00 into the pipe a The supply of oil will thus be diminished, and the mixture of air and oil will be weakened, thus producing an explosion of less force, and thereby reducing the speed of the engine to the normal condition, so that the governor again lifts therod 7a and admits a full supply of oil to the channel 9,

The throw of the pump is regulated by the screw 0 which is adjusted in the head a, so as to increase or diminish the upward and downward motion of said head 0 and the pistonrod (Z.

In my application, Serial No. 242,946, filed June 30, 1887, I show and describe the oilpump and an igniting device of a special construction, which I do not claim in this application.
