SIDNEY ZALESKI HALL, OF LONDON, ENGLAND.

INTERNAL-COMBUSTION ENGINE.

Specification of Letters Patent.

Patented Mar. 25, 1919.

Application filed January 29, 1918. Serial No. 214,403.

To all whom it may concern Be it known that I, SIDNEY ZALESKI HALL, a subject of the King of Great Britain and Ireland, residing at 76 Victoria street, London, S. W., England, have invented certain new and useful Improvements in and Relating to Internal-Combustion Engines, of which the following is a specification.

This invention relates to an improved governor, and more particularly a shaft governor, for controlling the quantity of fuel delivered to the cylinder of an internal combustion engine using liquid fuel, and more especially by the method in which the stroke of the plunger of the fuel pump used for delivering the fuel to the engine is automatically regulated to suit the variation of load.

The main object of the present invention is to provide a simplified construction of shaft governor.

The present invention consists in a governor, and more particularly a shaft governor for varyingthe supply of'liquid fuel to the cylinder of the engine in accordance with the load, which governor comprises a block secured to the shaft, one part of which is made of circular cross-section, its-outer peripherybeing concentric with the shaft, while another part thereof is formed vwith two fiat surfaces, a ring mounted on the part of circular cross-section so as to be capable of angular displacement thereon, its

outer periphery being concentric with the by way of example one mode of carrying the invention into effect Figure 1 is a sectional elevation of the ed thereon, while another part thereof, viz.,

[) is formed with two flat surfaces b b and carries an eccentric (Z which imparts the necessary motion to the plunger of the fuel pump delivering fuel to the cylinder of the'engine and is free to slide along the flat surfaces 6 b on the block. This sliding movement of the eccentric causes its eccentricity to be changed for the purpose of regulating the amount of fuel delivered to the engine. The ring 0 and the eccentric d are interconnected, preferably by means of a die e and stud f, in such a manner that when the ring is rotated relatively to the crankshaft, the eccentric is caused to slide along the flat surfaces 6 b on the block at right angles to the axis of the crankshaft. The eccentric is mounted in such a manner that it is restrained from any other relative movement except the radial sliding movement at right angles to the axis of the crankshaft.

Two centrifugally operated weights 9 and h are pivoted to the fly-wheel 2' at g and h respectively, or other carrier secured to the crankshaft a, their outward movement under the action of centrifugal force, in a direction at right angles to the axis of the crankshaft and around their pivots, being under the control of helical or other springs g and b respectively. The weights 9 and h are adapted to rotate the ring 0 during their outward movement, and this may be effected by connecting the weights to the rotatable ring 0 by means of studs and dies 7:, or by links, or any other suitable means.

The operation of the governor hereinbe fore described is as follows When the crankshaft is stationary, the springs 7 h hold the weights 7 and it against the boss of the carrier 2', the eccentric being then in such a position that it allows the maximum amount of fuel being delivered to the engine. Upon the engine starting to run, the weights 9 and it move outward around their pivots h, under the action of centrifugal force, and in overcoming the pull of their respective springs g and if, the latter become extended. This motion causes the ring to be angularly and maximumthrow '(see Fig. 3) to the end position: marked 13, correspondingto the minimum throw (see Fig. l), thereby effecting a gradual reduction in theeccentricity of the eccentric. In the same way,

whenthe weights 9 h move inward toward 7 V the center 10f the crankshaft, the operation 7 center of the eccentric will take a position 7 between the two positions marked A and V B so that the eccentricity will always --cor-' hereinbefore described is reversed. The

respond to-the loadon the engine at the par- "ticular moment, andthesupply of liquid fuel to the cylinder will be proportional to the load. a

- I wish ltitO be understood thatthe details for carryingthe invention into effect may be" modified in various respects without d6? 7 V partingfrom the spirit of'the' invention.
