ALEXANDER WINTON, OF CLEVELAND, OHIO.

EXPLOSIVE-ENGINE.

SPECIFICATION forming part of Letters Patent N o. 600,819, dated March 15, 1898.

Application filed .Tune 26, 1896. Renewed February 12, 1898. Serial No. 670,146. (No model.)

To all whom it may concern.-

Be it known that I, ALEXANDER WINTON, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Explosive-Engines; 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 pertains to make and use it, :reference being had to the accompanying drawings, which form part of this specification.

My invention relates to improvements in explosive-engines, and pertains to certain improvements in a governor therefor and an electric sparker or igniting device, which will be fully described hereinafter and particularly pointed out in the claims.

One object of my invention is to provide a simple and reliable sparker or igniting device for the explosive-chamber of the engine.

Another object of my invention is to provide' an improved form of valve regulated through the medium `of a governor for controlling devices which control the feeding of a hydrocarbon liquid to be vaporized and conveyed to the explosion-chamber.

In the accompanying drawings, Figure l is a view, partly in section and side elevation, of an engine with my improvements attached. Fig. 2 is a top plan view of the same. Fig. 3 is an enlarged sectional view showing the particular form of the valve for regulating the admission of pressure to a huid-feed regulator. Fig. 4 is an end view of my improved igniter. Fig. 5 is a perspective view of the same. Fig. 6 is a detail view of thelower end of the rod for actuating the igniter and the reciprocating pitman for actuating said rod. Fig. 7 is a side elevation of the same.

Referring now to the drawings, A indicates the engine-bed; B, the cylinder; C, the driving-wheels; E and F, the gearings, and D a pitman connected with a reciprocating rod G. The outer end of this rod G is reduced, as clearly shown in Figs. 6 and 7, and has its free end turned upward, as shown at a.' The gearings E and F are so timed that the igniter is only ignited at every other stroke of the engine, as is necessary in explosive-engines of this character, and need not be further described, the same being well understood by those skilled in the art.

In the head of the cylinder is arranged an oscillating shaft c, carrying at its inner end, Within the cylinder, a laterally-extending contact or sparking wiref. Attached to the outer end of the shaft or rod e is a crank h, the same Ybeing attached to the shaft c through the medium of aset-screw e. Connected to the opposite end of the crank h is a spring-actuated rod H, the lower end of the said rod being guided in a slot Q of a bracket P, which is suitably attached to the head of the cylinder of the engine. The lower end of this springactuated rod H is turned laterally, as shown, to form a bearing-head I. This head I has a rib or flanged, serving to form practically a groove or shoulder, as clearly shown in Fig. 6, with which the upturned end a of the endwise-moving rod G engages. connected with the crank h or may be connected with' the rod H itself, the opposite end of the spring being shown as connected to the bracket P, the function of which is to normally hold the rod H down, with its top R in contact with the bracket,as will be readily understood. The slot Q in the bracket P,

through which the lower end of the lever or rod H passes, is elongated to permit the rod A spring T is a lateral movement, and a spring U is provided for normally holding the lever or rod H in the position shown in dotted lines in Fig. 4L. A stud or projection ralso extends through the head of the cylinder and is provided with the sparking-army, operating with the laterally-extending arm f of the shaft e, and the shaft c and the stud z' are provided with wires K, which electrically connect these studs with a suitable battery or other electrical source.

The operation of this device is as follows: The rod G being reciprocated through the mediuln of the pitman B and wheel E and F from the main shaft of the engine, its upturned end a engages the shoulder formed by the rib d and in its outward movement forces the rod or lever H up, owing to the fact that the engaging edge I of the rod extends downward at an inclination to the line of travel of the rod G. This upward movement is against IOO the tension of the spring T, as before stated,

and the rod or lever H causes the arm f to engage the contact point or wire j, thus closing the circuit to the electrical source. The movement of the rod G is suflicient to carry its upturned end a beyond the end of the rib d, and immediately the arm or lever H is released and instantly drawn downward by the spring T, thus separating the contacts 7' and f, which causes a spark, as will be readily understood. These parts are so timed that the sparking is made at the proper time in the explosion-chamber, as will be readily understood. The crank h being adjustable upon the rod e, it can be set to cause the contacts f andj to properly cooperate.

From this description it will be seen that the sparker is oi' such a construction as to make it of absolute and positive movement and make positive and certain the creating of the spark at exactly the right time.

The admission of the explosive mixture is regulated through the medium of diaphragms f', situated within the cylinders J, the diaphragms being connected with the valves r, which control the inlet-openings for mixture, the diaphragms being subjected to pressure from a pump Z9, connected with the cylinders by pipes c c at points below the diaphragms,

whereby the valves r are allowed to open more or less or be entirely closed, according to the pressure beneath the diaphragms. Connected with the diaphragms f are bellcrank levers t', which in turn are connected with the huid-controlling valves n through the medium of the stems m. By means of this construction when the valves are opening for admitting the explosive mixture the fluidcontrolling valves 'n are moved away froml their fluid-opening to admit the fluid, and close the fluid-openings when the valves are closed, as will be readily understood.,

Situated in the pipe a above the Huid-controlling valve n are air-controlling valves s, connected with the upper ends of the bellcrank levers In operation when the inlet-Valves r are drawn inward for admitting the explosive mixture the diaphragms f connected therewith are correspondingly moved, which actuates the bell-crank levers t" and consequently moves the fluid and air controlling valves n and s for admitting air and hydrocarbon fluid, which produces an explosive compound.

A ball-governor L is situated at a point between the pump b and the cylinders J and serves to regulate an escape-opening b by means of a valve 2, connected with the stem of the governor. My present improvement in this valve 2 consists in extending the valve portion out and forming on its outer end a valve 3 in addition to the valve 2, whereby should the governor-belt become broken or otherwise accidentally injured the spring of the ball-governor L will draw its stem M outward, causing the valve 3 to close firmly the escape-opening Z9. The air then being forced into the cylinders J operates upon the pistons f therein and holds the inlet-valves r closed, thus shutting oft' both the ilow of fluid and air and causing the engine to automatically stop, as will be readily understood.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. An electric sparker comprising contactpoints, a rod as H connected with and adapted to move one of the contacts, the lower end of the rod having its end turned laterally to form an inclined plane, and a groove upon its inclined surface, and an endwise-moving rod adapted to engage said groove, the parts adapted to cooperate as described.
