ENGINE-GOVERNOR.

Specification of Letters Patent.

Application filed January 14, 1908.

Patented Nov. '7, 1911.

Serial No. 410,728.

To all whom it may concern:

Be it known that I, BAXTER M. AsLAKsoN, a citizen of the United States, and resident of Salem, in the county of Columbiana'and State of Ohio, have invented certain new and useful Improvements in Engine-Governors, of which the following is a specification.

My invention relates to governors for engines and the object of the same is to provide a governor of simple and durable construction in which the fly-weights will move in alinement with each other and exert their force against a single spring. Further features of novelty are clearly disclosed in the subsequent detailed description.

In the accompanying drawings,Figure 1, is a cross sectional view through the body of the governor casing, disclosing an end view of the fly-weights and supporting levers therefor. This view further illustrates the pedestal which supports the rotating parts and through which power is transmittedto drive the governor. Fig. 2, is a side view of the fly-weights mounted on their supporting levers within the governor casing, and a side view of the pedestal. Fig. 3, is a plan view of the fiy-weights and levers within the governor casing, the latter being shown in section. Fig. 4, is a perspective view of the casing base and the supporting levers with the fly-weights removed from the latter.

A, indicates a pedestal in the center of which is a shaft B vertically supported and carrying on its upper end the base 0, of the casing, the upper part or body C of which forms a cover for the fly-weights and levers which are mounted on the base 0.

Cast integral with the base G, are eight vertical brackets C G etc., spaced an equal distance on each side of a line drawn across the base C at its center, and disposed four on each side of said line respectively. In the upper end portion of each of said brackets is a hole which receives one end of a bolt D, extending across to the opposite bracket. Pivoted on the bolts are four U-shaped bracket-levers E, containing holes leading through their cylindrical base portions, through which the bolts D pass to support said levers in operating position.

The two end bracket levers E are each provided with a longitudinally extending lever E cast integral therewith and having a boss E located in nearly vertical alinement with a boss F of the vertical links F, which connect the ends of the levers E and the sleeve G. Locked in each boss E is a pin H, which is held in the boss by a set screw I, serving to connect the lever E to the link F.

Two fly-weights J, each of which are rec tangular in cross section, are held in pivotal relation to the bracket-levers E by cross pins N, N, etc., and are free to swing apart from each other when subjected to centrifugal force, but are limited in the distance they can so move,by a pair of longitudinally extending rods K, provided with enlarged ends forming shoulders adapted to abut against two bosses P, P, cast on the weights, supporting strips L which hold said rods in position being bolted to the fly-weights by bolts M, M, etc. The fly-weights each contain a cylindrical bore extending longitudinally therethrough in which a spiral spring 0 is located. A plate Q, closes one end of said bore and is connected to one of the flyweights by bolts Q. A threaded bolt Q passes through the plate Q, with the bolthead resting against the outside face of said plate and the thread of the bolt fitting into a nut held by one end of the spring, so that by turning the bolt Q the tension of said spring may be changed. The bolt Q is held in its adjusted position by a set screw S hearing within a hole in the plate Q, drilled at a right angle to the axis of the bolt Q3. The opposite end of the spring 0 is formed in a loop which extends into an opening formed in a plate R, which is a duplicate of the plate Q, and is held to the fly-weight in the manner before described, and one end of the set screw S in the plate R, projects through said loop, indicated at T, to hold same to said plate, as will be readily understood. The sleeve G contains an annular groove in which is fitted a ring indicated by V (shown in dotted lines) and adapted to remain stationary while the sleeve revolves, and fastened to this ring on opposite sides thereof is a bifurcated lever V, hinged at one end to an integral arm of the pedestal at W, and pivotally connected at its opposite end to a rod X, which carries at its lower end a piston somewhat less in diameter than the cylindrical bore in a chamber Y, the latter being pivoted to the pedestal at Y. The chamber Y is filled with liquid which is operated on by the piston to prevent undue shock in the governor by reason of sudden fluctuations of load on the engine.

Z indicates the gear wheel secured on the governor shaft 13, and in mesh with a similar wheel connected to a driven shaft of the engine and by means of which the governor is rotated.

In operation, the engine drives the gov ernor in the manner intimated, rotating the vertical shaft B, yoke G and easing base C, which supports the fly-weights J, and said fly-weights, being disposed on opposite sides of the center of the plate 0, are separated by centrifugal force to a predetermined degree according to the speed of the governor, against the resistance of the spring 0, the tension of which may be set to allow a certain relative movement of the fly-weights at a given speed of rotation of the plate C. The outward movements of the fly-weights are transmitted to the bracket levers E and E which are swung on their pivots D, causing their levers E to raise the links F and yoke G, and consequently, upwardly swinging the lever V and thereby turning the shaft V to which lever V is connected, a certain distance to control the valve or valves of the engine which are connected to said shaft TV, as will be easily understood.

The casing presented by the base C, and body C, may be made to be fairly air tight, the openings through which the links F pass being a close sliding lit, and the depressed character of said base adapting it to be filled with oil or grease to keep the parts thoroughly lubricated. The parallel position of the supporting bracket-levers causes the fly-weights to remain in relative alinement at all times and the position of the weights in the drawings is the position they would occupy when the governor is being rotated at the normal speed thereof and at the normal speed of the engine. The side rods K limit the distance the fly-weights can separate from each other, and in making very light governors for some purposes it is obvious that the two inner supporting brackets E could be dispensed with by allowing the side links K to act to hold the bores of the fly-weights in alinement and fitting them to the sides of the fiy-weights so as to secure a smooth sliding action between the parts, but in this case I should prefer to hinge the supporting brackets nearer the middle of the fly-weights.

The device is strong, simple and compact, is not easily deranged, and most of the parts are of duplicate construction which admits of low cost of construction and repairs.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
