GOVERNOR.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed August 15,1905. Serial No. 274,278.

To all whom it may concern.-

Be it known that I, ARTHUR ATWATER KENT, a citizen of the United States, residing in the city and county of Philadelphia, State 5 of Pennsylvania, have invented a new and useful Governor for Automobile-Engines, of which the following is a specification.

My invention consists of a novel construction of governor which is especially adapted to for use in connection with automobile or other engines and comprises novel means for manually and mechanically regulating the position of a friction-wheel with respect to a friction-cone, whereby any desired speed will 15 be caused to remain substantially constant and the flow of the explosive material to the engine will be controlled in the most positive manner, with an accurately-timed action and a delicate apportionment of quantity to load.

20 It further consists of a novel construction v of frictioncone and friction-wheel adapted to coact therewith, said friction-wheel being mounted upon a governorshaft having connections leading therefrom to the throttle de- 2 5 vice employed.

It further consists of novel features of construction, all as will be hereinafter fully set forth.

The figure represents a plan view of a govo ernor embodying my invention, the same being shown n assembled position.

Similar numerals of reference indicate corresponding parts in the figure.

Referring to the drawing, 1 designates the 5 frame or housing, in which is journaled a driving-shaft 2, having mounted thereon an engineer motor 3 of an suitable or conventional construction, an a fiy-wheel 4.

5 designates a gear fixed to the shaft 2 and gear 6, fixedly mounted on a shaft? which latter is journaled in suitable bearingsin the frame 1.

8 designates a friction-cone secured to the shaft 7 and with which the friction-wheel 9 5 is ada ted toengage.

1O esignates a shaft suitably supported and extending at an angle to. the shaft7, corresponding to the slope of the cone. 'One end of said shaft has a bearing in a standard 50 11 or its equivalent, the other end of-said shaft being also suitably supported in any desired manner and connected to other mechanism, (not shown,) if desired. Said shaft 10 has keyed or splined thereon the 5 5 friction-wheel 9.

12 designates a clutch adapted to engage the friction-wheel 9 and mounted on a suitable guide for the handle 13 of the shifting mechanism, which handle is adapted to be manually controlled.

- 14 designates a governor provided with a collar 15, fixed to the shaft 10 by means of as'et-screw 16 or similar device and also pro' vided with a sliding collar 17, having a groove 18 therein, with which the arm 19 of the bent rod 20 has engagement.

21 designates a bearing or journal in whichthe rod 20 is movably mounted. 20 has connected at its other end one end of a link 22,

the other end of said link being connected to a throttle mechanism 23.

The operation is as follows: The rotation of the engine-shaft 2 is imparted to the shaft face of the friction-cone, which will conse-- quently vary the speed with which the shaft 10 rotates and the position of the loose collar of the governor mounted on the shaft willbe correspondingly varied. As the speed of the governor varies the sliding collar 17 will ad-" vanceor retreat on the shaft 10, and as the rod 20 has engagement therewith and also with the throttle mechanism 28 it is apparent that any change in the position of the sliding collar 17 with respect to the shaft 10 will cause the throttle mechanism '23 to be opened or closed, as the case may be. In governors for automobiles as heretofore generally constructed there has been'considerable difficulty in regulating the speed of the engine vwhen the automobile is traveling downhill. In my present novel construction the position of the friction-wheel 9 with respect to the cone 8 may be manually or mechanically varied at will, so that any desired speed will be substantially constant.

If any variation occurs, the governor will cause the sliding rod 20 .to actuatethe throttle mechanism, so as to regulate the admission of the explosive mixtures to the engine. It will be ap arent that I obtain the same result if I fix t e cone 8 on the driving-shaft 2 as I do when I employ the intermeshin gears 5 and 6 and mount the cone 8 on the s aft7 and I'considerthis to be an equivalent construction to that shown and described.

' It will be apparent from the foregoing. that c by the nove combination of the frictionwheel 9, splined to the shaft and adapted to coact with the friction-cone 8, I am enabled to obtain the desired result, a simple construction and arrangement of the parts which are readily accessible for the purpose of inspection and repair at all times. It-will further be apparent that I am enabled by my novel construction to manually and mechanically set the friction-wheel 9 in substantially the desired'position or tovary the same mechanically with respect to the friction-cone, so that any desired speed will be substantially constant, since if any variation occurs the governor will cause the sliding rod to instantly actuate the throttle mechanism so as to regulate the admission of the explosive mixtures in the engine. It will also eapparent that the shaft 10 and the bearing 21' and its adjuncts may be supported from any fixed point in any suitable manner, according to requirements, and that various changes in the manner of assembling -the parts'may be made without departing from the spirit of my invention.

It will be evident that I have omitted form the drawing various details relating to the internal construction of the engine and governor and their adjuncts, since the same are .7 familiar to those skilled in the art'and form per se no art of the present invention.

It will e apparent that while I have shown as one embodiment'of my invention a cone and friction-wheel for changing the ratio of speed ofthe shafts 7 and 10 I do notdesire thereof any speed-changing device, such as to be limited in every instance thereto, since it will'be apparent that I may employ in lieu two cones and a belt or a friction disk and wheel or the like or any other equivalent 1 ing devices intermediate said throttle mechanism and frictionwheel.
