v INTERNAL COMBUSTION ENGINE GOVERNOR Filed Dec. 5, 1955 Patented Feb. 2 1937 UNITED STATES PATENT OFFICE INTERNAL COMBUSTION ENGINE GOVERNOR Application December 5, 1935, Serial No. 53,044

1 Claim.

This invention relates to an automatic governor for the throttlevalve of the carburetor of an internal combustion engine and primarily a stationary internal combustion engine.

It is particularly aimed to provide a novel construction which may be readily applied to existing engines as well as be built into engines initially.

The invention resides in the combinations and details of the novel, fool-proof construction more specifically hereinafter described and shown in accompanying drawing.

In said drawing:

Figure 1 is a side elevation of an engine equipped with my improvement;

Figure 2 is a plan view of the parts of Figure 1;

Figure 3 is a vertical sectional view taken on the line 33 of Figure 2;

Figure 4 is a detail section taken on the line 44 of Figure 2.

Referring specifically to the drawing, wherein like reference characters designate like or similar parts, Hi designates a conventional internal combustion engine, for instance, of the stationary type, having among other parts, a carburetor H, equipped with a throttle valve [2 mounted by a rotatable spindle l3, and also having a detachable cylinder head I 4 secured in place by bolts l5.

In carrying out the invention, a bracket I6 is detachably connected to the engine as by means of two of the bolts l5 as shown. Such bracket It has an upstanding portion I6 equipped with an inwardly turned lug IT, to which a bearing member I8 is fastened. A Vertical post l9 having tapered ends pivoting it in recesses in bracket l6 and the end of bearing member I8 is pivoted to mount an L-shaped rod 20, the post l9 having a shoulder [9 to support a loop on the end of the rod 2|]. Rod 20 has a main portion 2| and a lateral portion 22. The main portion 2| is riveted or otherwise fastened to a governor plate 23, while the portion 22 has a horizontally directed end 22 that is connected by means of a link 26 to a rod 2'! pivoted at 28 to a crank 29 in turn rigidly connected to the spindle l3 of the throttle valve. The connection between link 26 and rod 2'! is provided by passing an angular portion 21a of rod 2'! through an opening in an enlargement 26' on the link 26, and. then upsetting the free end of the rod 21 as at 211).

The governor plate 23 has secured thereto an arm 3! which extends rearwardly from the post I9. Such arm is preferably arcuate as shown, and has an eyelet 32 of a contractile coil spring 33 adjustably connected thereto by engagement with teeth 35 thereof. Said contractile spring 33, in turn, is connected to a plate 35, fastened as by means of another of the bolts I 5 to the cylinder head M or other suitable parts. 5

The governor plate 23 is preferably slotted as at 37 to fit around the mounting 33 for the shaft 33 which mounts and drives the fan 46, all forming part of the internal combustion engine l0, and designed in operation to cool such engine.

In the operation of the engine, and starting from an idle position, wherein the throttle valve I2 is open and urged to open position through the contractile action of the spring 33, the starting of the motor I0 by operating the fan 40 causes the 15 air from the latter to impinge the governor plate 23 to rock on the axis of the post l9, counter to the tension of the spring 33, thus moving the end 22 rearwardly and accordingly actuating the rod 21 in the same direction, and accordingly turning the crank 29 and closing the throttle valve partially or wholly in accordance with the speed of the engine. Such parts move toward normal position under the urgency of the spring 33 in proportion to the diminution of the speed of the engine.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

We claim as our invention:-

In combination with an internal combustion engine, its throttle valve, the cooling fan and operating shaft for the latter; a governor plate for the throttle valve, said governor plate being disposed between the front of the engine and said fan and having a slot through which said shaft passes, a bracket having a horizontal portion fastened to the engine, said bracket having an upwardly extending portion and an inwardly extending lug, a rod fastened transversely across the governor plate, a post extending through one end of said rod, said post having a conical end provided with a shoulder in contact with the rod, a set-screw carried by the lug engaging the other end of the post, said rod having a downwardly extending portion, a connection from said portion to the throttle, an arm extending inwardly from said rod above the horizontal portion of the bracket, and a contractive spring connected to the said arm and to the engine urging the parts to a position corresponding to the open position of the throttle valve.
