INDICATING-GOVERNOR.

Specification of Letters Patent.

Patented Oct. 17, 1916.

Application filed March 23, 1915. Serial No. 16,490.

This invention relates to devices for controlling the flow of a fluid through a conduit, and more specifically to governing devices for internal combustion engines.

In accordance with my invention, the speed of the engine is controlled by automatically controlling the flow of mixture from the carbureter to the engine so that when the engine speed exceeds the predetermined normal the supply of' mixture or motive fluid will be reduced, thereby reducing the speed of the engine.

The objects of the invention are to provide a' governor of this class, in which a controlling valve is actuated by a part of the motive fluid,to control the flow of all of the fluid and also to provide. an indicating mechanism which will show the positions of the control valve and indirectly show the power of the engine and loss of fuel through leakage of pistons, valves, etc.

The invention is illustrated in the accom panying drawings in which Figure 1 is a side elevation of a conduit connecting a carburetor with the intake pipe of an internal combustion engine; Fig. 2 is a longitudinal section of the same; Fig. 3 is a transverse section on the line 33 of Fig. 2 and Fig. 4 is a-section on the line 44 of Fig.3. Y

Referring to the drawings, 10 indicates the section of the conduit which is connected with the carburetor, and 11 the section which is connected with the intake pipe of the engine. The section 10 of. the conduit is provided with the usual throttle valve 12 whereby the supply of motive fluid maybe manually controlled. Between the sections 10 and '11 is a section 13 in which a balanced butterfly valve 14 is arran ed. Extending upwardly from the butter y valve 14 is a partition 15, which may be secured in the section 13 in any suitable manner, and the upper part'of which is corrugated, as shown at 16, and curved substantially about the axis of a-shaft 17 on which a grid valve 18 is secured. The partition 15 divides the current of motive fluid into two streams, and the corrugations at 16. have a tendency to create a whirlpool in the stream of fluid at the outer edge of the valve 18, this whirlpool reacting on the edge of the valve and tending to makethe flow more uniform and also prevent surging motion of valve.

Mounted on the valve 18 is a grid 19 having lugs 20 to which a link 21 is pivotally connected. The link 21 has a fixed fulcrum at 22, and is provided with a laterally projecting lug or toe 23 which is adapted to engage the end of an adjustable screw 24 for the purpose of limiting the swinging movement of the valve 18 and thus limit the speed of the engine. It will be seen that as the valve 18 swings upwardly from the position' shown in. Fig. 2, the grid 19 will be moved toward the partition 15, and the ports through the valve and grid will be thrown out of register and thus restrict the opening through the valve. The valve 18 is connected with the valve 14 by means of a link 25, so that the valve 14 is swung from the position indicated in Fig. 2; as the valve 18 rises.

The valve 14 has an opening 26 which, perthe valve 18, and the tension of the spring may be adjusted by rotating the cap 29, the cap being held in any position to which it is adjusted by means of a detent 31 which is adapted to engage the notches 32 in the outer surface of the cap. The detent 31 is held in engagement with the notches 32 by rBneans of a spring 33, as clearly shown in (%n the exterior of the section 13 of the conduit there is secured a dial 34 having scales 35 thereon for indicating the position of the valve 18 and, indirectly, the power of the engine. A hand 36 is pivotedat 37 and has connected therewith a pinion 38 which meshes with a gear segment 39 on the .shaft 17, so that as the shaft 17 rotates in accordance with the movements of the valve 18, the hand 36 will be moved over the scales 35.

A casing 40 is arranged to cover the screw 24 and also the cap 29 in order to prevent unauthorized adjustment of these parts.

he. casing 40 is pivotally connected with he section 13 of the conduit, at 4:1, and is se cured by means of a padlock or other suit- 5 able device 42.

Inthe operation of the device the motive fluid passing through the conduit is divided into two streams, one passing on, the left 7 hand side of the partition and-the other 0 on the right hand side thereof, as seen in go of'flow of motive fluid will be in propor- 3 Fig. 2. The flow on the right hand side of the partition 15 causes the valve 18 to-be lifted, and the movement of the grid 19 on' the valve restricts the opening through the 15 valve and thus regulates the flow of the motive fluid. The valve 14 is also swung toward the closed position, as the valve 18 rises, so that the valve 14 controls the flo-w on both sides of the partition 15. The rate tion to the speed of the engine, and when the engine speed becomes excessive, the velocity of the motive fluid will be so, great end of the screw 24. The opening 26 permits the motive fluid to flow on the right hand side of the partition 15 when the valve 14 reaches the closed or nearly closed position. I

The power developed by the engine will ordinarily be'in proportion to the amount of motive fluid supplied thereto, and the. po- I sition of the valve 18 will, indirectly, indi- 85 cate the rate at which the motive fluid is being supplied-to the engine, andtherefore, the position-of the hand 36, which at all times corresponds'with the position of the valve 18,.will also indicate the power developed by the engine. The s ring 27 may be adjusted so thatthe fuel wi 1 be supplied to the en ine at the required rates to produce desire speeds under given condition of load and the graduations 35 made to indicate the 4 normal speeds for diflerent positions of the through the other branch of the conduit.
