VARIABLE sPEEI GOVERNORM" Filed March 21, 1944 2 Sheets-She e t 2 Patented Feb. 13, 1945 UNITED STATES PATENT ()FFICE 2,369,397 V VARIABLE- SPEED GOVERNOR Paul G. Kostenick, Scobey, Mont. Application March 21, 1944, Serial No. 527,433 Claims. (61. 123-103) This invention relates to a novel and improved variable speed governor for use in connection with gasoline orDiesel motors wherein the 80vernor means proper is operated by and through the medium of oil pressure supplied by an appropriate lubricating pump connected with the crankcase or fuel transfer pump on Diesel motors, whichever the conditions may be, and my primary aim is to provide a new type of governor to replace the conventional mechanical ball-type centrifugal governor ordinarily used on presentday internal combustion engines and motors.

Briefly, the improved governor construction is characterized by an oil pressure actuated diaphragm embodied in a special oil cylinder or receptacle therefor, this being a spring-returned type having direct mechanical connection with the engine throttle, oil being delivered to said cylinder by a conduit leading from the sourceof oil supply and said conduit including a circulatory p pin elevation, bringing out the construction and arrangement of individual details to a degree of greater clarity and sufficiently, it is believed, to reveal all essential parts of the governor and its associated adjuncts.

Referring now to the drawings by distinguishing reference numerals it will be observed that More specifically, the diaphragm-equipped oil cylinder has a return line connected thereto, the 'return line also connecting with the crankcase,

and there being handeregulated valve means associated with the return line adjacent the cylinder for thus enabling the user to predetermine and obtain the desired nicety of regulating control.

In carrying out the preferred embodiment of the invention I have devised a unique structural arrangement characterized by a minimum of parts thus insuring efliciency in simplicity, the parts chosen being so coordinated to cooperate in insuring full throttle control over the full speed range of an engine, whereby to provide for-more effective and selective speed control results.

Other features and advantages will become more readily apparent from" the following description and the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the same: i I

Figure 1 is a side elevational view of a conventional internal combustion engine, with certain parts omitted for clearness of illustration, this showing the variable speed governor as conceptacle 'or cylinder.

the numeral 3 designates the aforementioned re- This is of appropriate material and dimensions and suitably mounted on the cylinder block as brought out in Figure 1. At the right hand flanged end 4 I provide a suitable closure plate 5whose outer marginal portion is bolted or otherwise secured to the flange 4. The central portion of the plate is somewhat concaved and provided with a bearing having a suit able packing gland 6 through which a control rod 1 reciprocates. This rod is secured at its inner end to a concave-convex diaphragm 8. More specifically, the rod I is bolted or otherwise connected with the central portion of the diaphragm and a coiled spring 9 surrounds the rod, bears at one end against the bearing in and at its opposite end against the diaphragm connection. The outer perimeter of marginal edge of the diaphragm is clamped between the flange 4 and the closure plate 5. This spacing of parts 5 and 8 provides a chamber between the'two.

While considering this end of the governor structure it will be noted, in Figure 2 that the conventional throttle II is actuated by a crank a'rm I2 and intervening link l3, the latter being pivotally connected to the crank arm and likestructed in accordance with the principles of the instant invention and illustrating its preferred association with conventional parts and including, further, auxiliary devices acting as corn-v ponents of the governorstructure as a unitary arrangement.

Figure 2 is a view partly in section, and partly wise pivotally connected to the push-pull control rod 1. Oil is introduced into the left-hand end of the cylinder 3 by way of an inlet or feed neck I4. The oil delivery line or ,conduit I5 is connected, suitably, to this neck M. The intake end of the line l5, as indicated at the point I6, is connected to the crankcase A (in case of a Diesel motor hook-up this pipe end "5 would be connected to the fuel oil tank not shown). An appropriately driven circulating pump I1 is mounted in the conduit to pick-up th oil from the crank case A and to deliver it into the cylinder? by way of the line IS. A Y-shaped valve casing I8 is embodied in the conduit and is provided with a ballcheck valve l9. There is also a branch pipe 20 which leads off from this coupling or connection to deliver lubricating oil to the engine and other parts thereof, (or as in the case of a Diesel 611-," gine, fuel oil to th fuel injection system).

A substantially T-shaped valve fitting or casing 2| i mounted atop the central portion of the cylinder 3, having communication therewith through the branch indicated. A return line 22 leads from this valve casing 2| back to the crankcase A to serve a purpose to be hereinafter explained. A needle or equivalent valve 23 coacts with the seat 24, this valve being on an adjusting rod 25 operating through an adapter branch 26. A coil spring is located in this tubular branch 26 and surrounds the rod and exerts pressure on the shoulder, as indicated, to assist in opening or ,unseating said valve 23. The rod 25 is screw-threaded as at 21 and operates through a screw-threaded sleeve 28 on an attaching bracket 29, this being fixedl mounted on the dash as shown in Figure 1. For purposes of adjusting th screw-threads the rod is provided with an appropriate hand-grip 30. A branch pipe 3|, which serves as a by-pass, affords communicating. connection between the oil return line 22 and the chamber which is formed in the cylinder at a point between the diaphragm 8 and closing plate 5. Oil which accumulates in this chamber acts as a lubricant for the rod 1 and bearing Ill to promote movements of operation of the parts and such oil can be bled from the chainber'by way of the plug screw 32. A imilar drain plug 33 is provided in the bottomof the cylinder 3, this also for purposes of Qdepending portion 35 which connects with a con- .trol wire 36 which is, in turn, operable through a flexible shaft 31, said wire being pushed back and forth by a knob or finger-grip 38. This flexible shaft or wire 36 provides an auxiliary hand control for the governor control rod 1.

Explaining the operation of the invention, it can be seen that when the lubricating pump I1 is in operation, oil is drawn up from the crankcase A and forced up and by the ball check valve l9, then on up through the pipe and into the cylinder 3 by way of the inlet M. The oil in this cylinder exerts pressure against the diaphragm 8 forcing it against the spring 9 and causing the throttle H to close by means of the operating or connecting rod 1, thus causing the engine to slow down. When higher speed is de sired, the valve 23 is opened, this by means of the control rod 25, which relieves oil pressure in the cylinderagainst the diaphragm, thu allowing the pring 9to force the diaphragm back and to open the throttle I I. The overflow of oil escaping through this valve 23 is returned to the crankcase (or to the fuel tank in the case of a Diesel motor) by means of the return line 22. It can be seen that b properl setting the valve 23, that is, in a predetermined position, an equally predetermined pressure will be maintained in said cylinder 3 acting on the diaphragm and, therefore, holding the throttle in a fixed or one position. 'When, however, the motor load happens to vary, causing it to slowdown, the oil pump i1 will obviously decrease its output and lower the pressure in the cylinder 3. which causes the throttl to open. If the load becomes lighter, the engine would tend to speed up and cause the pump to increase the output and also increase the pressure in the cylinder, exerting pressure on the diaphragm, which would decrease the throttle opening by way of the control rod 1. The obvious purpose of the bracket or element 34 is that of an auxiliary control to manipulate the throttl when the governor is not Operating as in the case when the engine is to be started. As before stated, the auxiliary control element 34 is under the influence and action of the flexible shaft 36 and its operating finger-piece 38.

It can be seen that the valve 23 acts as a means of variable speed control due to the fact that the oil pressure in cylinder 3 is controlled by manual adjustment of this valve which, in turn, determines the actions of the diaphragm 8.

The purpose of the check valve [9 is to prevent oil from draining out of the governor control mechanism, whereby to keep said mechanism in readiness, at all times for sensitive functioning.

It is thought that persons skilled in the art to which the invention relateswill be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in the shape, size and arrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.
