Application file'rl August 13. 1900. Serial 110.26.714. (No model.)

To all whom it may concern:

Be it known that I, CARL W. \VEIss,a citizeuof the United States, residing in the borough of Manhattan, in the city, county, and

State of New York, have invented certain new and useful Improvements in Governors for 'llydrocarbon-Engines, of which the following isa specification, reference being had to the accompanying drawings, forming a part hereof.

This invention relates lac-governors for hydrocarbon-engines whereby the speed ofthe engine controls the delivery of oil to form the basis of the explosive charge. In common with other governing devicesof this type an 1 5 eccentric or cam is operatively connected with the plunger of the pump which supplies the charge of oil to the cylinder, the position of such eccentric or cam being shifted with variations in the speed of the rotating part; but,

unlike the previous devices, the transmission mechanism between the eccentric and the plunger isso arranged as to give aquick hammer-like blow to the plunger. Heretoforethe eccentric-strap has been connected positively with the plunger, giving to the latter a gradual movement. In the present invention the plunger is operated with a. hammer-like blow, which causes the oil to be' injected quickly and forcibly; so that it is completely and instantly vaporized in the cylinder, to the great improvement of the action of the engine. g

The invention will be more fully described hereinafterwith reference to the accompanying drawings, in which- Figure l is a plan view of a'hydrocarbouengine equipped with the improved governor, some parts being broken out and shown in section to illustrate details of construction.

40 Fig. 2 is a detail view in section on the ,plane indicated by the broken line 2 2 of Fig. 1, on aslightly larger scale; and Fig. 3 is a detail plan view of the parts shown in Fig. 2.

In the engine chosen for illustration of the application of the invention the cylinder A is represented as provided with an extension or crankchamber-A in the walls of which the crank-shaft C has its bearings.

crank-shaft or upon the hub of one of the flywheels 0 is pivotally mounted a weight (J to Upon the swing toward or from the axis of the crankshaft, being held normally toward the axis by a spring C. The pi voted weight or weighted arm- C is provided with-a short' arm or link c for the purpose of connecting the same operatively with an eccentric D. The latterhas an elongated opening (1 to receive the shaft 0 to permit the eccentric to he moved transversely with respect to the shaft to decrease or increase its eccentricity as the 6: weight or weighted arm (l moves farther away from or toward the axisof the shaft with the increase or decrease in the speed of rotation, the eccentric being compelled to retate with the shaft through its connection with the weight or weighted arm 0 and the connection of the latter with the shaft or with the liy-whee'tsecured thereon. An eccentricstrap E embraces the eccentric and is connectedbya rod E in the construction shown in the drawings with one arm "F of a bellcrank lever, which issuitably supported on' the engine, the other arm F carrying a roller f to strike against the end of a reciprocating rod Fflwhich in turn operates the plunger of a pump G, which supplies oil to the working cylinder to form the basis of the explosive charge, the plunger being returned bythe action of a spring.

- It will be seen that with every change in the speed of rotation of the shaft 0, no matter how'slight, the throw oi the eccentric, and consequently the edective movement of the pump-plunger, will vary accordingly, so that the quantity of oil fed to the cylinder will be varied in exact accordance with the requiremen ts of the varying conditions of load under which the engine is operated, and, furthermore, the throw of the eccentric being greater than the stroke of the plunger, which is operated by contact only, the plunger will not follow the gradual movement of the eccentric, but will be operatedwith a quick ham mer-like blow and will inject the oil forcibly and at the proper instant.

As a detail of construction which may be employed to advantage in connection with the governor mechanism already described for convenience in starting and in stoppingv engines of the type referred to the contact- 100 red F which slides freely in its support on the engine and is held against the arm F by the action of tlie spring g, surrounding the plunger of the pump, which bears against said rod, has seemed thereto a pin or projection It in the path of a pin or projection h on a lever H, which is pivoted on theengine. In starting the engine the lever II is manipulated. to throw'forward the rod F and consequently the plunger of the pump, thereby forcing into the cylinder of the engine a sufficient quantity of oil .to form the basis of the first explosive charge. For the purpose of stopping the engine a sliding latch I is mon nted in the support of the rod F to be pushed into engagement with a notch i in the rod F when it is pump is held in its forward position against the action ofthe spring g.

I claim as my invention- The combination with a hydrocarbon-cugine having a pump to deliver oil directly to the cylinder or explosion-chamber, of an eccentric mounted to move transversely with respect to the axis of the engine-shaft,a weightpivotally mounted upon said shaft and connected to said eccentric to shift the same as the speed of the engine varies, and operative connections between said eccentric and the plunger of said pump, said connections ineluding a part moved by the eccentric with a throw greater than the stroke of the plunger and operating the plunger, by contact, with a hammer-like blow to inject the oil forcibly and instantly, substantially as shown and described.

This speci fication signed and witnessed this 9th day of August, A. D. 1900.

CARL W. \VEISS.
