B001, 01' HINSDALE, ILLINOIS, ASSIGNOR TO THE CONTINENTAL ILLINOIS BANK AND TRUST COMPANY, OF CHICAGO, ILLINOIS, CORPORATION OF ILLINOIS GOVERNOR Application filed April 11, 1930. Serial No. 443,265.

This invention relates to a governor and has for oneobject to provide a governor adapted particularly for use in connection withinternal combustion engines in which the governor is located somewhere in the intake line, so that the governor is afiected in its operation by the air which is drawn into the engine.

One object is to provide .a device. in which a member is used which is moved by the movement of air into the engine and in which a resistance is provided against movement of the member, this resistance being progressively increased as the movement increases. Another object is to provide in connection with a governor of this general type a locking mechanism. A further object is to provide an adjusting means whereby the original resistance to motion of the governor may be adjusted. Other objects will appear from'time to time in the specification.

. and claims.

My invention is illustrated more or less diagrammatically in the accompanying drawing, wherein:

Figure 1 is a sideelevation of a portion of the intake passage of an internal combustion engine showmgmy governor in position;

' Figure 2 is a transverse cross section taken 'on line 2-2 of Figural;

Figure 3 is a cross section taken on line 3-3 of Figure 2;

Figure 4 is a cross section taken at line 4-4 of Figure 2.

Fig. 5 is a diagram showing a modified initial position of the gears.

Like parts are designated ters-throughout the specification and drawng A is a portion of the intake passage of an internal combustion engine. The carbure- ,tor A maybe situated so as todischarge into' this passage. The governor is located in the intake line of the engine and preferably between the carburetor and the combustion chamber.

The governor includes a housing B which is provided with a more or less rectan ular bore or passage B. 'B is a cylindrical arby like charac-.

ing cavity formed in the chamber B. B B are holes formed in the member B by means of which it may be attached in any suitable manner in connection with the intake passage A.

Ash it C is journaled in the cavity. B and it has fastened to it a valve member C whichapproximates the shape and size of the passage B Fastened to the casting B is agovernor housing D, which may be lrreg'ularly shaped as shown. At one end, as at D, it is preferably of reduced size. In the inside of the reduced portion D is formed an enlargement D On either side of the enlargement D which takes the form of a groove, there remain members D D, which are rovided with bores D D respectively.

7 is a rojection extending into the interior of t e housing D. It is rovided with vided with a lug E which may fit into the notch D. At its opposite end it is provided with a projection E which is perforatedas at E. This projection fits into the enlargement D when the cover plate is in osition.

F is an adjusting screw provide with. a reduced portion F at one end, which portion is adapted to be inserted into the perforation D in the member D. At its opposite end the screw is provided with an enlarged head F which is notched as at F. The screw may'have in the' sides of the is providedwith a downof which the lock may be locked and unlocked and rotation effected. The details of the locking mechanism are not shown as they form no particular art of the present invention This su cient that a locking I I provided and. that the v adjusting projecting member G "which,when

. head F a groove F, within which a lockin a screw can be locked against movement and can be unlocked to permit movement.

H is an adjusting screw nut. It is provided with a flat side H adapted to bear against the interior of the wall of the housin in the reduced portion D. It is provi ed with a threaded perforation H within which the shaft of the screw F is threaded. Rotation of the screw causes longitudinal movement of the nut. Extending from one side of the nut is a projection H provided with a perforation H. v

A spring I is fastened at one end in the perforation H of the projection H.

The shaft C .projects at'one end into the housing D. At that end and within the housing, it has eccentrically mounted upon it an elliptical gear J.

Mounted in the'boss D which is provided with a perforation, is a short shaft K. Eccentrically supported on this shaft is a second elliptical gear K which is in mesh with the first mentioned elliptical gear J. The gear K' may have a plurality of perforations or other positions of attachment K formed in it. In one of these a pin K is positioned. One end of the spring I is fastened on the pin K It will be realized that while I have shown and described a practical operative device, nevertheless many changes might be made in the size, shape, number and disposition of parts without departing materially from the spirit of my invention and I wish, therefore, that my showing be taken as in a sense diagrammatic. In particular, the initial position of the gears before movement of the butterfly valve takes place might be altered. As here shown, the longest radius of the gear K is opposite the shortest radius of the gear J. This might be -the arrangement but is not necessarily the arrangement. The gears might in their initial position be arranged in almost any other manner, as for example, the position indicated in Figure 5. The initial position of the gears might thus be almost infinitely varied to suit the varying requirements of a very wide range of engines. The gears might be of different sizes and for some purposes it would be satisfactory to have the attachment of the spring on the gear carried by an extension which might project radially or axially beyond the gear.

The use and operation of my invention are as follows:

The invention may be embodied in any mechanism in which the movement of a fluid through a passage is to be controlled. In the form illustrated it is applied to control an internal combustion engine. It thus acts as a speed governor for the engine. The spring tension being adjustable is originally set or adjusted so that the force acting upon the butterfly valve as the result of the movement of the fluid past it will be balanced by the resistance to movement caused by the spring and thus the governor acts to control the size of the passageway through which fuel may move into the engine and by reason.

shaft carries rotates with it, thus rotating the second elliptical gear with which it meshes. One end of the tension spring is'attached to this second elliptical gear. As the gears move in the direction indicated by the arrows in Figure 3, the tension spring is constantly stretched further and as the gear to which it is mounted continues to move, the

radius of motion is increased and thus the power required to stretch the spring further increases in proportion as the movement of the butterfly valve continues and thus with each added increment of movement of the valve, the resistance to further movement increases in an increasing proportion.
