DANIEL C. JENKINS, OF CLARKSBURG, WEST VIRGINIA.

Encina-REGULATOR.

Specicaton of Ltters Patent.

Application led March 6, 1916. Serial No. 82,478.

To all whom t may concern:

Be it known that, I, DANIEL C. JENKINS, a citizen of the United States, residing at Clarksburg-in the county of Harrison and u State of lV est Virginia, have invented certain new and useful Improvements in En gine-Regulators; 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 appeitains to make and use the same.

This invention relates to engine regulators, and has for anobject to provide a construe.- tion especially adapted for use in conjunction with internal combustion engines 4to prevent the introduction of the full charge of gas at starting and thereby eliminate the intense wasteful and damaging explosions at starting, and also facilitating starting by 4reason of the compression in the cylinder being less than the normal running compression. A further object of the invention is to provide a governor in conjunction with an internal combustion engine for controlling the action of the valves as an ordinary speed regulator, with improved means interposed between the governor and the valves for temporarily partially closing the valves at starting, with means for gradually returning the parts to normal after the engine has started.

lVith these and otherobjects in' view .the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

` In the drawings Figure 1 is a diagrammatic view showing theconnection of the improved device with an internal Ycombustion engine.

Fig. 2 is an enlarged detail sectional view of the regulator.

Like characters of reference designate corresponding parts throughout the several views.

The. improved device which forms' the subject-matter of this application isadapted to be connected and operated in conjunction with any usual and ordinary type of eXplo-v sive engines, here shown conventionally only as valve housing 10 with a valve 11 mount-- ed therein. The valve 11 is actuated by a bell-crank lever 12 which in turn` is actuated from a bell'crank lever 13 through connec/ting devices including a link composed of the two parts or sections 14 and 15. The

lin any usual and ordinarv .the length thereof,

bell-crank lever is controlled by. a governor 16 of any usual and ordinary. type, driven manner as by the Interposed in the run of the lilik 14-15 is mechanism for varying its length. This is here shown as a cylinder 18 rigidly connected with one of the sections, as the section 1 4, with a piston 19 slidably mounted within the cylinder 18 and rigidly connected with the other section, as 15, o f the link.-

Within the cylinder 18 is a spring 20 normally tending to hold the piston at the eX;

treme of its movement and the link 14-15 at lits greatest length. Means is provided, however, as the flexible pipe 21 for actuating said mechanism pneumatically by admitting air to the cylinder 1.8 against the piston 19 to move the piston within the cylindenagainst the tension of the spring 20. The air from the flexible pipe 21 passes through the valvehousing 22 check valve 23. It is well known, of course, that compressed air is used in starting large internal combustion engines, and at the vtime the compressed air is employed for this purpose it is by my invention also admitted through the pipe 21. As soon as the engine starts the compressed air is shut oif, and the air is trapped by the valve 23 in the cylinder 18, holding the piston with the combined link 14515 shortened and the adjustable stop 24 against the gland 25. llVhen, however, the air is shut off the trapped air leaks through the bleederQG under the pres- Sure of the spring 20, permitting the piston lifting the 'Y 19 to 'return slowly to normal and the composition.

Throughout the specification referencelias been made to admitting air to the cylinder 18. It is to be understood that the air is used only as illustrative of any Huid under pressure conveniently at hand for `actuating the piston within the cylinder.

I claim i 1. The combination with an engine valve, a centrifugal governor, devices connecting .said valve and governor; of mechanism interposed insaid devices to temporarily vary and means receiving fluid pressure simultaneously with a starter and connected tosaid mechanism.

'2. 'Ihe combination with av valve, a governor, and a connection between them; of

ofmechanism to vary the length ofsaiddevices, pneumatic means for actuating said mechanism, and'means to automatically restore the devices to normal.

4. The combination with an engine valve anda governor therefor; of a link composed Vof alined sections connected respectively to the; valve and governor, members connected with, the sections and telescopic on each other, and means receiving air pressure simultaneously With a starter, operative to slide said members by said pressure to reduce the'length ofthe link, and means to gradually restore the parts to normal after starting has been accomplished.

5. The combination with an engine valve and a' governor therefor; of alink connecting the valve and the governor composed of sections slidable relative to each other, means, receiving air pressure as utilized for startingthe engine, to vary the length of the link, and means to gradually restore the parts to normal after starting has been accomplished.

' 6;l The combination of a valve and a governor therefor, a link connecting the valve and governor 'composed of sections, a cylinder carried by one section, a piston carried by th other section slidable Within the cylinder, a spring tending to hold the piston at one end of the cylinder, means to admit air to the .cylinder to move the piston against the tension of the spring, means to trap the air Within the cylinder, and means to permit the air to gradually bleed out of the cylinder under the expansion of the spring.

Y

8. The combination with an engine valve,

.9. Thel 'combination of a valve and a governor therefor, a link connecting the valve and governor and composed of sections, a cylinder carried Vby one section, a piston carried by the other section and slidable Within the cylinder, means to admit air to the cylinder to move the piston in one direction, means to trap. the air vwithin the cylinder, and means to permit the air to gradually bleed out of the vcylinder and the piston to move in the other direction.
