SPARKING IGNITER FOR EXPLOSlVE-ENGINES.

SPECIFICATION forming part of Letters Patent No. 727,399, dated May 5, 1903.

Application filed November 23, 1901. Serial No. 83,418. (No model.)

To on whom it may concern:

Be it known that I, EMIL MAERKY, a citizen of the Republic of Switzerland, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Sparking Igniters for Explosive-Engines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in sparking igniters for gas or gasolene engines; and the object of my invention is the provision of a simple, inexpensive, durable, and practical device which will operate reliably and perfectly to ignite the charge of gas or gasolene.

With this object in view my invention consists of an electric igniter embodying novel features of construction and combination of parts, substantially as disclosed herein.

In order that the details of construction of my igniter may be fully understood and its numerous advantages be fully appreciated, I have illustrated in the accompanying drawings mechanism constructed in accordance with and embodying my invention.

Figure 1 represents an end View of my igniter mechanism. Fig. 2 represents a transverse sectional view of the end or head of a cylinder with mymechanism in position therein. Fig. 3 is an .end view of my invention, illustrating the position of the parts just before the spark is formed.

Referringby numerals to the drawings, the numeral 1 designates the head of a cylinder which is provided with a chamber 2, in which fits the plug 3, which has the wings 4 to receive the nuts 5 for securing the plug in the chamber of the cylinder head. Passing through the plug is the pin or shaft 6, which carries at its inner end the arm 7, provided with a contact-point 8, and t0 the outer or exposed end of the shaft is secured the oppositely-extending arm 9, which normally rests between the clamping or gripping device, which is composed of the lever 10 and the right-angled lever 11, both of which levers are mounted upon a stud 12, common to both levers, and the angle-lever has its vertical arm 11 provided with an opening 11 which fits upon the curvedguide-rod 13, which de pends from the inner end of the straight or horizontal lever, and around the guide-rod is placeda coiled spring 14, which bears upon the arm of the angle-lever and the inner end of the horizontal lever and brings the fingers of the two levers into close engagement with the arm 9 and at all times holds the said arm 9 between said fingers, and when the inner end of the horizontal lever is struck by the projection 15 on the shaft 16 the clampingfingers are elevated and turn the shaft which carries the contact-point. Passing through the plug and parallel with the shaft 6 is the pin 17, which carries at its inner end the con tact-point 18 and at its exterior or exposed end receives the electric connection 19 for making, with the electric connection 20, the circuit to produce the spark between the contact-points and the cylinder to ignite the charge, as will be evident.

From the foregoing description, taken in connection with the drawings, the operation of my invention will be readily understood, and I will state that the revolution of the shaft carrying the projection brings said proj ection at the proper time in contact with the end of the lever, which slightly lifts said 10- ver and also the clamping-fingers, which turn the arm on the outer end of the shaft, this turning of the shaft bringing the arm with the contact-point on the inner end of said the inner end of the rigid pin, making the circuit. When the projection 15 passes out of engagement with the lever 10, the spring 14 causes said lever to strike the arm 9, thereby separating the electrodes and cansing a spark which ignites thecharge in the cylinder, and this operation is repeated continuously With an even and reliable action, and the spring-controlled angle-lever insures the gripping of the clamp upon the arm on the outer end of the shaft, and a reliable op eration is certain.

It is evident that I provide an igniter which is of extremelyinexpensive, simple, and durable construction and can be easily applied to the cylinder-head of the engine and that is thoroughly efficient for the intended purpose.

shaft into contact with the contact-point on ing device to hold it in proper engagement with the rock-shaft, and means for operating the lever to rock the shaft to bring the points together.

In testimony whereof I affix my signature i in presence of two Witnesses.

EMIL MAERKY.
