The rod 76 is made of convenient shape and length to reach from the arm 51 to the lever 81 to which it is properly jointed'at 81. lThe lever 81 fulcrumed at 82'may be of the Well known type of controlling levers mounted in a sector frame 83 provided With notches 84 in -Which fit the end of the locking-bolt 85. The locking-bolt 85 is controlled by the rod 86 and lever 87. See Figs. 1 and 2.

While the drawings indicate threaded ends, 2 and 7, it is not to be understood that this is to be the Xed form, as in some types of engines, or in larger units, other forms of joining may be required, as, for instance, flanges, gaskets, and bolts, necessitating a correspcnding changein the form of the ends 2 and 7.

The operation ofthe mechanism whenapplied to an explosion engine is as follows: The engine beingl in motion draws in air through the inlet pipes and discharges it through the exhaust pipe. This current of air passing through the carbureter takes up the vapor of the hydro-carbon and so passes into the cylinder Where it is exploded, thus accelerating the motion of the engine and also increasing the velocity of the air .passing through the inlet pipes. This air passing through the carbureter 12, the nipple 10, and the spaces between the arms 14 of the guide 3, impinges against the valve 15. By reason of the enlarged chamber 4, the carbonized air passes over the edge of the valve 15 and through the passage 16, impinging against the plate 40, passes through the openings 44, into the rear of the openings 44, and tending to move limpinging -against the valve 15 and plate 40 tends to move the valveend plate in the direction of theflow of air, when moved a sufcient distance in this direction the valve 15 moves up to and closes the passage 16. As

the inertia of the engine causes it t0 continue to rotate, `a partial vacuum is formed in the inlet pipe 46, the reducer 18 and the chamber 6. The partial vacuum causes the air in the carbureter to press against the valve 15 moving it still farther into the pas-l sage 16, carrying with it the stem 36, the

plate 40 and the fork 65 and lengthening the retractile spring 6.2.` The plate 40 may be so spaced with regard y20 to the valve 15, that when the valve 15 just enters the passage 16 the cylindrical rim 43 is about touncover the openings 17. Then when'the valve 15 moves into the passage 16 the rim 43 will uncover the openings 17 allowing .uncarbonized air to iow through the'ope'nings into the chamber .6, impinging against the plate 40, as it passes through the the plate ,in the direction of the flow of air. Passing 301through-'the openings 44 in the plate 40 into therear of, the chamber 6, 1t continues through `the openings between the arms 33 of the guide' 20,' through .the reducer 18l and the inlet pipe or pipes 46 to the cylinder 35 or cylinders-88.` As the air is'uncarbonized -it will pass through the cylinder without exploding and, consequently, there will be the retardation due to compression, friction and Whatever". work' the engine may be doing..- 4o This will' overcome the inertia of rotation, which-rin trn will diminish 'the ow .of air through-the inlet pipes, lessen the impact yof vthe incoming air againstthe plate 40 and perm-it theretractile spring 62 to return thefork 65 to its normal position. The fork 65 having the ends of the tines bearing against the shoulder 37 will move the shoulder 37, the stern 36, the valve 15, and the plate 40. to their normal positions. This will bring the cylindrical rim 43 forward, closing the openings 17 and carry the valve 15 out` ofthe passage 16, allowing the carbonized air to How through the carbureter 12, the

nip-ple 10, the openings in the guide 3, the 55 -chamber 4, impingingagainst the valve 15,

owing around the valve 15,through the passage 1 6, into the chamber 6, v'impinging against the plate `40, passing jthrough the openings 44, through the remainder of the chamber 6,"through theopeningsin the guide 20, through the reducer 18,A and through the inlet pipe or pipes 4 6', to Athe cylinder or. vcylinders 88, vwhere it is compressed and exploded,- accelerating the rotation of the engine, and so repeating the operation.

sleeve 58 sliding freely on the .rod 63 and held in 'place by the trunnions 57 worlfifng in the holes 56 formed in the slippers53,

fitted to the sliding-ways 52, will be moved-v toward the vforli 65 when the arm 50- is moved toward the fork 65, and will be moved toward the eye 64 when the arm 5.0 is .moved..}i.,. z.' i

toward the eye 64. Because the fulcruin' 25 of the lever 49 is at a distance from the fulcrum 68 o f the rod 63thc distance from the center of the trunnions 57 to the center of the ,fulcrum 25will vary as the arm 50 is moved toward the fork 65 or toward the eye 64. And, consequently, the slippers 53 will be moved toward the fulcrum 25 when the .arm 50 is moved toward the fork 65, and the slippers 53 will be moved toward the head 54 when the arm 50`is moved toward the eye 64. The moving of the slippers 53 toward the `fulcrum 25 increases the tension of the retractile spring 62, while. the moving of the slippers 53 .toward the head 54 diminishes the tension of the retractile spring 62. Also,

the placing of the fulcrum 25 -toward the fork'65 permits the greatest tension of the retractile spring 62 to be delivered with almostits full force to the shoulder 37 when the arm 50 is moved to its nearestI position tothe fork 65, and decreases the force of the spring on the shoulder 37 whenzthe, arm '50 is moved toward the fulcrum 68, both'by reasonof the diminished tension of the retractile spring 62 and the leverage ofthe rod 63 from the ends of the tines of the fork 65 to the fulcrum 68, over the distance from center .of trunnion 57 Vto vfulcru'm 68. The lever 49, ,being connected by means of the arm 51, the rod 7 6, and the proper joints, to,v the lever 81; may be moved so as to bring the arm 50 toward the `fork 65 or toward the eye 64, by moving thelever 81 in the proper v direction thus increasing or diminishing the tension of the spring 62, and, consequently the resistance of the valve 15 and'plate 40 to being moved from their normal positions.

Hence, by properly moving the lever 81, the

resistance of the valve 15' and plate 40 may beso altered that they will be moved from: ,their-normal positions whenever the rotation of the engine, or engines, having the cylinder or cylinders 88, exceeds the desired velocity. v The'lever '81 having the notched sector 83 and bolt 85 can be set to .any desired position and so hold the rotation vof the engine at any predeterminedvelocity.

As the velocity of the engine may be changed* at thev will of the operator, the necessity for speed gears, especiallyfor mobile machines, -as, for instance, automobiles, will be greatly lessened, or may be entirely done away with, placing themachine under can be accomplished by stepped gearing.

4more perfect control of the operator than,-

It will beseen-from the-.above description that when van engine exceeds thel desired le it is, therefore,

velocity it Will pump cool air through the cylinder, thus cooling its Walls and relieving the radiators. l

lAs the governor is intended to be applied to all forms of engines and vary according to their use and malte, it is impossible to sliov.' in one drawing all the variations the governor with its frame, levers and rods would have to undergo to fit each engine,

understood that I do not intend to conne myself to the form shown but to adapt it to the various makes of engines, and that I do not intend to confine myself to joining the lever to the stem by 'i havin@ the fork 65 bear aOainst the shoulder end of the stem, the rear end of the stem; viz.,

. 37, as in thevarious adaptations it may be found more expedient to connect the lever 63 in front of the valve l5, at the forward or, to have it bear against the en'd to the left of the plate 4:0.

It will also be seen that it is immaterial Whether the chambers 4 and 6 are formed ,integrally or are separated, or, Whether the valve l5 and plate il() are mounted on the same stem or on separate stems properly connected; or, Whether plate all), or its equivalent, is placed in and operated by the eX- haust instead of the intake, so long as the valve and plate l0 are operated by the passage of a liuid Whose velocity is coni C' it Works,

. and desire to secure trolled by the engine.

It will also be seen that Where an engine is desired to be run at a given velocity the be made to operate the valve and plate Without the medium of the frame and levers.

It will also be seen' that it is not necessary that the plate lit the chamber in Which nor that it be perforated, for, the holes may be provided at the area of the periphery of the plate in any manner sired.
