The present invention relates to an engine governor for controlling the speed of an internal combustion engine'especially in auto mobiles, trucks,.tractors and the like and the prime object of the invention resides in the provision of a governor'structure of'this nature which is controlled by the air current 7 set up by the fan and the movement of the vehicle. I

A still further very important object of the invention resides in the provision of an engine governor of this nature which is exceedingly simple in its construction, easy to install, strong and durable, not likely to easily become out oforder, easy. to adjust, thoroughly efiicient and reliable in use and operation, and otherwise well adapted to the purpose for which it is designed. a a

With the above and numerous other ob jects in view as will appear as the descrip-. tion proceeds, theinvention resides in certain novel features ofvconstruction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing: t Figure l is a side elevation of an engine showing our governor structure mounted thereon,

Figure 2 is a top plan view of thegovernor, Figure 3 is a rear elevation thereof, Figure 4 is a sectional view taken substantially on the line H of Figure 2, and

Figure 5 is an elevation of the vane plate and its attached bar.

Referring to the drawing in detail it will be seen that the engine'disclosed herein is of the conventional type including the block structure 5, cooling fan 6, and carburetor 7 among the usual other well known elements.

The letter A denotes a U-shaped bracket, the bight 8 of which is disposed vertically merging at its upperend into a'relatively n long horizontal leg 9 and at its lower end in a relatively short horizontal leg 10. The leg 9 is adapted to be fixed to the motor block 5 by means of one of the usual stud bolts asso ciated therewith. r r

A shaft 11 is journaled through the legs 9 and 10 and has a crank 12 on the upper end thereof and a crank .14 on the lower end there of. A link 15 connects the crank 14 with the throttle valve of the carb'uretor 7. An L- shaped bracket. 17 is mounted on'the front of the engine block and has another L-shaped bracket 18 fixed thereto to provide spaced parallel arms a bolted together as at PA EN OFFICE 19 and having a member 20 rock'able therebetween with an opening 21 formed therein through which is extended a bar 22 on one end of which is a vane plate 23 to be affected by the current of air set up by the fan 6;

The other end of the bar 22 has a link25- engaged therewith and this link'25 is engaged with the crank 12. A bracket 26 is fixed to the bracket A and a bolt 27 is engaged there with by means of a thumb nut 28. A spring 29 is-fix'ed tolthe-bolt 27 and to the lever 22 and the tensionof the spring29 may be adjusted by turning the nut 28 as willbeap parent.

From the above detailed description it will be seenthat as the motor picks up speed the air current'created by the fan- 6 will be increased forcing the vane plate 23 rearward- 1y and rocking the bar 22 thereby pulling forwardly on the link 25 to' swing forwardly on the cr'ank'12 thus rocking the shaft 11 and swinging thecrank 14; forwardly topull on the link 15 which tends to-close'the throttle valve of the carburetor 7. r

- The tension bathe-spring 29, of course, controls this governor and can be regulated to regulate the speed'of the engine.

I It is'thought that the construction, operation, utility and advantages of-this invention will n'ow be quite apparent'to those skilled in this art without a more detailed description thereof; 1 I v The present embodiment of the invention has been disclosed in detail merely for the purposes of exemplification' since in actual practice it attains'the-features of advantage enumerated as desirable in. the statement of the invention and the above description.

It will be apparentthat chan es in the details of construction, and in t e combination and arrangement of parts may be resorted to without departing from the spirit or scopeof the invention as hereinafter ing claimed or sacrificing any of its advantages. Having thus described our invention, what we claim as new is: a

1. A governor structure of the class described comprising a bracket adapted to be mounted on the front of an engine block, a

bar, means for r-ockably mounting the bar in the bracket, and a vane on one end of the bar, a link engageable with the other end of the bar, a second bracket on the side of the engine block,:a shaft rockable in the second bracket and having a crank at the upper end with which said link is engaged, a crank at the lower end of the shaft, means for operatively connecting the lower crank with the throttle valve of thecarbureter.

2. A governor structure of the class described comprislng a bracket adapted tobe mounted on the front of an engine block, a

bar, means for rockably mounting the bar in vthe bracket, and a vane on one end of the bracket, a link engageable with theother end of the bar, a second bracket on the side of p the engine block, a shaft rockable in the sec- ,ond bracket and having a crank at the upper end with which said link is engaged, a crank at the lower end of the shaft, means for operatively connecting the lower crank with the throttle valve of the carbureter, spring means associated with the bar, and adjustable means associated with the spring.

A governor structure of the class described comprising a bar, means for rock ably mounting the bar forwardly of the engine block of aninternal combustion engine,

a vane on one end of said bar, a shaft, means for rockably and vertically supporting said shaft to one side of the engine block, an operatingfconnection between said bar and one end of said shaft, and means for operatively connecting the other end of said shaft with the throttle valve of a carbureter.

l. A' governor structureof the class described comprising a bar, means for mountthe bar for rockable movement on a horizontal plane at the forward end of an engine block of an internal combustion engine,

a rock shaft, means for mounting said rock shaft vertically on one-side of the engine block, cranks on the upper and lower ends of said rock shaft, a vane on one end of said bar, end of said bar with the crank on the upper end of said rock shaft, and means for operatively connecting the crank on the lower end ofsaid rock shaft with thevthrottle valve of the carbureter and adjustable, spring means operatively connected with said bar adjacent the last referred end of said bar.
