MEANS FOR OPERATING OIL-ENGINES.

Specification of Letters Patent.

Patented Jan. 16,1912.

Application filed August 19, 1910. Serial No. 577,965.

To all whom itmag concern:

-- Be it known that I, LEON WYoonsKY, a

subject of the Czar of Russia. and a resident of New'York city, borough of Bronx,

ing power engines and particularly to means employed to automatically control the amount of oil delivered to the cylinder of oil engines.

The object of my invention is to provide a governor by means of which the proper amount of oil can be injected to form a combustible charge. I

\..'t'urther object or" my invention is to provide a governor which will start to injcctthe oil at the same point of rotation, that is to say when the main crank is in a certain position regardless of the load, the governor will act to start. the injection of oil, and to govern the volume of oil'delivered by the distance which the the pump piston.

A turtheuobject is to provide a governor which will autonnitically stop the action of the pump in case theengine should accidently back-fire and run backward.

A further object is to providea governor free from the reaction of the governed Inecha nism.

Referring to the drawings which form a part of this specification Figure l is a view of the governor and pump shown partly in seccionand embodying my invention. Fig. 2 is an end view of the governor-with the cap removed and disclosing the fly-weights pivoted therein. Fig. 3 is a cross sectional view on line a2':c of F igLfZ. I

A indicates the oil pump which is shown governor cam projects the piston and the caniQ on the governor acts to causethe delivery stroke of the piston as will be more fully explained hereinafter.

I indicates a governor casing within which are pivotally connected two fly-weights indicated by J and J respectively, one end of the fly-weight J being hinged to a pivot J 2 H which is connected to the casing and the flyweight J hinges on a pivot J which is also connected to the casing at a point opposite the pivot J 1 The fly-weight J is provided at its pivoted end with a projecting, link J 4 which is formed integral therewith and its projecting end is provided with ahole J 5 in which is fitted a pivot'pin J on which is hinged a coupling rod K which extends downward and is connected to the fly-weight J by a pivot K. I

Fastened near the upper-end'ofthe fiy- 'weight J by means of a screw .L is a spring L which extends to near the periphery of the casing I and is held to said casing by a screw the spring being connected under a predetermined tension and in a proper position well understood in the art.

' The casing is mounted on a governor shaftf M which is provided with a screw threaded recess M to receive the end of a screw N which passes through ahole N in the casing adjacent to the shaft. The screw N is provided with a central hole which extends through the same longitudinally and serves to hold the shank O of a radial lever O which extends at right. angles to the shank O, and carries at its extreme end a finger P which slides in contact with" the top Q of cam-lever Q, which cam-lever is pivoted to the casing at Q, and is forced into its outer position by means of a coilspring Q one end of which is attached to an extension of the cam-lever Q and the other end of which is connected by means of a screw Q to the casing.

A link R is pivoted at one end to-the flyweight J hy-a'pivot R and its opposite end is pivoted to the radial lever O by a pivot I. The dotted lines indicate the of the link and radial lever O w ien the cam is in a more depressed position into 'which position it is thrown by the action of the governor when the governor is worked at higher speed.

The casing I is provided with an opening osition I located in its lesser periphery and one end of the cam-lever Q projects through this opening beyond the outer periphery thereof and is formed so thatits periphery presents an arc of a circle having its center at Q So that in moving on its pivot it presents a camsurface Q to the roller (Land the height of the cam is reduced as the cam-lever Q travels toward its lower position, thereby reducing the throw of the cam and consequently reducing the stroke of the pump while starting the action of the cam at the same point of its revolution. This-cam-lever beside the curve Q- described above, has two morecurves Q and Q. Curve Q is underthe action of the finger P, which may occupy different positions, according'to the opening of the governor weights, and is guided by the inner periphery IQof the circular rim of easing I, besides being, pivoted at the center of this periphery at :Q. This curve Q is so constructed as to change the height of the cam Q", in proportion to the angle described by the radial lever O. I

When/the governor rotates in a counter-' clockwise manner, the roller C striking the cam Q tries to turn same in a clockwise manner, which motion is resisted by the finger P; this finger being thus jammed and held by the force of friction between the in ner periphery of casing I and cam-curve Q In the case shown in the accompanying drawings, the governor is fixed at the free end: of a shaft, and the radial link is pivoted in the center of this shaft, utilizing at the same time the turned inner part ofthe casing I as a guiding surface. Of course the governor may be fixed at any part of the shaft and the radial lever may be pivoted in any other point of the casing and a special guiding surface I, concentric with the pivot may beprovided for. Another alternative would be to connect the finger P, by means of a connecting link to a pivot It,

properly attached on the fly-weight; without any radial lever whatever, provided space permits. This link is introduced to obtain the necessary leverage for the transmission of motion from the fly-weight J to the finger P. N o matter what is the position of the cam-lever Q, the beginning of the action of the cam-surface Q", owing to its circular shape is always the same. The cam-surface Q is used when the engine reverses,,owing a to back-firin which often occurs when starting. The governor supposing is running in a closkwise direction, the roller C is striking first the surface Q and compels the cam-lever Q to collapse entirely, thus stopping the action of the pump and cutting off the fuel supply until the engine is running in the right direction, (in the case illustrated the'governor is supposed to run in counter-clockwise direction.)

movement, thereby multiplying the power of.

It will be readily understood that the roller C rolls in contact with the outerrsur- -face of the casing I as illustrated, being held in contact by the spring H. In operation, the casing is driven through the instrumentality of the shaft M which is usually driven from the main crank-shaft.

As the cam-surface Q contacts with the pump roller C, the roller and piston A is forced inward a certain distance depending on the position of the cam Q.

For illustration, if the speed of the governor is above normal, which is usually the case when the load on the engine is suddenly reduced, the fly-weights are forced apart by centrifugal action, thereby forcingthe lever 0 toward its right hand position indicated in dotted lines, thereby depressing the camface Q correspondingly, and since the cam Q is pivoted at such a point to the casing as to bring its cam-surface Q within the casing when the governor is working at its highest speed, thereby withdrawing the cam from cooperative contact with the roller C under this condition, no'action would be imparted to the oil pump and therefore the engine would slow down, and as the engine speed is reduced, the cam-lever Q would gradually raise and project the cam-surface Q beyond the periphery of the casing and causing it to contact with roller 0 and give a definite stroke to the piston, depending on the exact position of the lever Q. 'It is therethe fly-weights when the finger P is jammed between I and Q It is obvious that the fly-weight J= might be dispensed with together with the coupling r'od K, but ,where the governor is made small in dimensions and weight, for operating a pump working at a high pressure, I prefer to use a plurality of fly-weights in coupled relation as shown.

Having thus described my invention what- I claim as new:
