ELECTRICAL IGNITER FOR HYDROCARBON-ENGINES.

$PEGIFIGATION forming part of Letters Patent No. 654,693, dated July 31, 1900.,

' Application filed February 16, 1899. fierial No. 705,665. (No model.)

To all whom it may concern:

Be it known that I, HUGO WEGELIN, engineer, a subject of the Emperor of Germany, and a resident of Augsburg, in the Kingdom of Bavaria, in the Empire of Germany, have invented certain new and useful Improvements in and Relating to Hydrocarbon-Engines, (for which I have made application for Letters Patent in Great Britain, No. 15,927, bearing date July 21, 1898,) of which the following is a specification.

This invention relates to hydrocarbon-engines, and comprises means foreffecting ignition of the motive fluid in which a continuous current may be employed or in which an electromagnetic inductor is employed for the periodic generation of current to effect ignition as required.

The objects of the invention are to effectively provide for the adjustment of the time of ignition and for the regulation of the amount of compression, according to the quality of the explosive charge, the load, and other conditions.

The invention consists in one part in the provision of an operating tappet or cam for effecting periodic making and breaking of the circuit of a continuous electric current with an oblique rear edge which may break contact sooner or later, as may be required to effect early or late ignition, and in another part in the provision of an adjustable cam for operating the exhaust-valve operating-lever, such cam being provided with two projections to respectively operate the exhaustvalve, according to the amount of compression required or as the ignition is effected early or late.

The invention is illustrated in the accompanying drawings, in which Figures 1 and 2 are respectively part side elevation and plan of a motor applied with the improved means for effecting ignition, Fig. 3 is a part plan of a motor in which the ignition-gear is slightly modified and an ad justable cam is provided for operating the em haust-valvelever. Fig. 4is adetail plan view of the adjusting means. Fig. 5 is a detail end view of said means, parts being in section.

In carrying the invention into eifect a tappet or cam e is provided integral with or so cured to a spunwheel d, rotating upon a spin= of the contact early or late ignition may be effected, the early ignition being effected on the adjustment of the spring-contact 9 into ,the position indicated in full lines in Fig. 2,

while late ignition is effected upon its adjustment into the position indicated in dotted lines in that figure.

Integral with or secured to the tappet or cam e and spur-wheel d is a cam m, provided for the purpose of operating the exhaust-valve lever i by contact with the roller 1, provided at its extremity. When it is desired that the exhaust-valve should be opened on the compression-stroke, so as to reduce the amount of compression such, for instance, as when running at a reduced load or when starting the parts are arranged as shown in Fig. 3. The tappet c and spur-wheel d are provided adjustable, so as to slide on the spindle cl, the contact-spring 9 being accordingly fixed. The cam for operating the exhaust-valve lever is in this case provided with two projections m and n, the former of which operates the exhaust-valve on the exhaust-stroke no matter what the position of the tappet e, while the latter is arranged to open the exhaust-valve only when the tappet is in position for late ignition, the cam being shown in this position in Fig. 3. readily started without compression, while when running at a reduced load the com pression may be wholly or' partly prevented. When it is desired that the exhaust valve shall not be opened on the compression-stroke-'= namely,when the tappet c, Fig. 3, is to be ar-.- ranged for early ignition-the tappet e is moved along its spindle 01 until the projec tion 41 clears the roller Z, in which position,- however, the projection m will contact with the roller Z, as usuah'so as to open the ex. haust valve on the exhaust-stroke. The 0011- tact arm g is held in any of its adjusted posi tions by means of a screw 9 By such means the motor may be The electrodes are shown at a: in Fig. 2, and these are of ordinary form, forming no part of my invention.

The battery is indicated at 1 and the electrical connections at .2, the circuit being completed through the frame and the shaft (Z.

The adjusting means for the tappet and cam a is shown in Figs 4: and 5, such means consisting of a bell-erank 3, pivoted on a bracket 5 and operated by a rod l, the free end of the bell-crank. being provided with rollers 6, bearing one on each side of the wheel (Z, to which the cam n is secured. Operation of the rod 4 will cause the wheel, and therefore the cam n, to slide on its shaft (1.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is--- 1. In combination in an igniting device for gas-engines, a contact-piece, electric connections controlled thereby electrodes in said electrical connections and a tappet having an inclined edge adapted to effect early or late separation for early or late ignition according to the relative position of the contact and tappet, one of said parts being adjustable in relation to the other and means for operating the tappet as described.

2. In combination, in an igniting device, a rotary cam or tappet, an arm to engage the same, one of said parts being adjustable relative to the other, a shaft carrying the tap pet, said tappet having its edge inclined with respect to the plane of the axis of rotation, electrical connections controlled by the arm and tappet and electrodes in said electrical connections substantially as described.

In combination in an igniting device for hydrocarbon-engines, a rotary tappet having an inclined edge, a device to engage the same, one of said parts being adjustable in relation to the other longitudinally of the inclined edge, electrical connections controlled bysaid tappet and said device and electrodes in said connections substantially as described.

In combination in an igniting device for gas engines, a tappet having an inclined edge, the crankshaft, a pinion mounted on the crank-shaft, a spurnvheel connected to the tappct, said spur-wheel rotating at onehalf the speed of said pinion, a contact to engage the tappet electrical connections controlled by the tappet and contact, and elcctrodes in said electrical connections, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
