THROTTLE AND SPARK GDVERNOR.

Application filed June 24, 1909. Serial No. 504,168.

To (ill whom. it may concern Be it known that- I, Vmcmvr LINK, a. citizen of the United States, and resident of of Michigan, have invented certain new and useful Improvements in Thrott eand Spark Governors. rf which the following is a specification. i

This invention relates. to hydro-carbon engines and in particular to agovernor which controls the s'peedthereof and also controls the ignition system.

Inhydro-carbon eng nes it is desirable that thespark be advanced as the engine s 'ieeds up and athigh speed the'ig'nition must occur before the piston starts on the power stroke. It is therefore desirable to connect the ignite!" with the governor ofthe engine so that when the speed rises "the spark will be automatically advanced. In engines ofthe above type. especially when used for driving motor vehicles, as now con- StIllCtCfl. the governor or its connections are exposed; The result is that it may easily be tampered with. This is undesirable where the driver of the vehicle inexperienced and perhaps irresponsible.

The objects of this ii'iveution are therefore to provide a governor which will. by a simultaneous n'ioverncnt. advance the spark and control the speed of the engine by throttling or otherwise, to house the governor and its connections. and to arrange the mechanism so that it may not be tampered with without breaking" a seal and disconnecting. the mechanism or both.

This invention therefore provides means for obtaining the above results. The govcrner shaft has m unted upon it a suitable centrifugal device which rotates therewith. A s eeve is mounted uppn this shaft. and directly connected to arms extending from the centrifugal device. The lower end of the sleeve is connected by means of an arm to the shaft which supports the mixture throttle valve. I The commutator shaft is located in a'linemcnt with the governor shaft and slidablv'connected with thesleeve so as to turn therewith. the engine speeds up. the centrifugal device ygill simultanecusly move the sleeve axially and angularly on the governorshaft. thereby simultaneously throttling the mivture and, advancing the spark by ad vancing the commutator shaft with resncrl to the governor shaft.

(The mixture pipe is preferably located adjacent the governor, and the governor and its connections are housed and protected by a cover whichtmay be. sealed in place by a suitable seal band or wire. Theconnnutator shaft is mounted for rotation in the cover plate and is removable therewith, so that when the cover is removed the commutator is disconnected and the motor rendered inoperative. Thearm which connects the governor to the throttle shaft is preferably so arranged that when the governor is discon nected this arm will close the throttle. It will thus be seen that when the governor is tampered with the entire motor is rendered inoperative,- and it will require a skilled worlnnan to connect the parts pro rly. The entire housing with its parts may ii: removed frcm the motor as a unit.

ln the drawings: Figure 1 is a longitudinal sectional view through the governor and commutator shafts on the line 1-l. Fig. 3; Fig; 2 is a plan view of the commutator with its cover removed: Fig. 3 is a section on the line 3--,--fl Fioj. 1: Fig.4 is a section on the line 4- -4 Fig. 1: Fig. 5 is a section on the line 7: Fig. i: Fig. 6 is a detail view of the governor in elevation: Fig. 7 is a detail nlan view of the governor with the commutator shaft disconnected; Fig. 8 is a detail of the sleeve and commutator shaft showing the slidable connections.

Referring to the drawings. 20 represents a portion of the crank case. 21 one of the cylinders bolted thereto. as'shown at 22. 23 the cam shaft. which is driven from the crank shaft by the usual, two-tmoiie gears, represents a portion of the carbureter, and 2.3 the intake pipe; the intake pipe being connected by suitable connections to the cylinders. 'ln the intake pipe are mounted a pair of butterflv throttle valves 27. 28. the thrott e valve 27 being manually controlled from the steering wheel. while the valve 28 is automatically controlled by the governor 99 in a manner hereinafter to be described. From the. above arrangement it'will be seen th. at the mixture may be controlled manually from the streringr wheel. and this control is independent of the operation of the governor controlled valve 99. This valve 28 being connected to th governor is out of the operators control. and it is the purpose. of this invention to suitably house the governor so that this throttle valve cannot be tampered Patented Aug. 25, 1914.

with and therefore will absolutely control the maximum speed of the engine.

Upon the governor shaft 30 is mounted a bevel-gear 31, which meshes with the bevel gear 32 mounted upon the cam shaft 23. Rigidly secured to the shaft 30 are a pair of radial arms 33, upon which are pivotally mounted the governor links 34 provided with the usual balls 35. A sleevenilt is loosely mounted upon the "shaft 30 and provided with a pair of annular flanges 37, which receive a shoe 38 pivotally connected to an arm 39, secured to the operating shaft 40 for the throttle valve 28. The sleeve, as shown in detail in Fig. 8, is provided. with a pair of bearing lugs or trunnions 41, upon which are slidingly and pivotally mounted the blocks 42, connecting the trunnions with the arms 43 secured to the governor links 34. By means of the above arrangement the governor links will simultaneously move the sleeve 36 axially'andangularly on the shaft 30. i

The shaft 3Ov is provided with ca nib 44", andaxially arranged withrespect to the shaft 30' is the commutator shaft 45,"which is separated from shaft 30 --by means of a sleeve 46,.the arrangement being such that shaft *6 ma move an ularly with respect to the shaft 30. Suite moun'tedwithina casing is a commutator 47 provided with segments 48 mounted in a ring of insulating material, preferably fiber.. Upon the shaft 49 is mounted "a rotatingarm 50 carrying a. contact roller 51, which is constructed to successively contact with the commutator segments 48.. The segment-s48 are connected by means of a metal st'rip.,52 which forms one of the terminals of the circuit, the other terminal being grounded on the motor frame. The lower end of the commutator shaft'is provided with feet 53 which slide between standards 54 upon the sleeve 36, the arrangement being such that sleeve 36 may move axially with respect to shaft 45 and still be connected with it so as to rotate it.

Upon the shaft 30 is mounted a governor spring 55, bearing-against the lower flange 37 on the sleeve 36 and against a roller thrust bearing 56. From the above arrange- *ment it will be seen that the connections beto'the shaft 30, and thus advances the spark. It will be noted that the intake ipe '25 is located adjacent the governor. he governor is housed by a suitable housing 57, which preferably is integral with the intake pipe. This housing is provided with a tubuvided with an opening 59 through which the bevel-gear 31 may be inserted into engagement with the bevel-gear 32. The tubular portion 58 is provided with a flange 60, whereby the housing may be secured to the crank case 20 by bolts, as shown in Fig. 1 A suitable bearing sleeve 61 is provided for the governor shaft 30.

The housing 57 is closed b a cover 62 provided with an extension 62 A tube 63 connects this extension with an extension 63' on the comm'utatorcasing 64. This tube 63 forms a casing for thecommutator shaft and. is provided with hearing sleeves 65. The cover 62 is secured to the housing 57 by means of bolts 66, provided with eyes or rings 67 for receiving a seal band or wire (58, the ends of which may be sealed together by .aseal or lock 69. The bevel-gear 31 projects from the housing 57, and the opening 59 is of larger diameter than this bevelgear so that it may be inserted into position in mesh with bevel-gear 32. The housing 57 which supports and incloses all of the working parts may be removed as a unit.

From the above it will be seen that the governor absolutely controls the throttle 28 and simultaneously controls the position of the spark, the entire mechanism being housedlso that it cannot be tampered with. without detection. In order to tamper with the governor it is necessary that the seal be broken and the cover plate 62 removed. Since this cover plate supports the commutator shaft, the commutator will be disconnected and therefore the engine rendered inoperative. If the governor is disconnected from its throttle valve the arm 39, weighted by the shoe 38, will automatically operate to additional means for rendering the motor ihoperative. Even if this throttle valve arm 3:3 be tied down there is alwaysthe possibility of making an inaccurate connection between the sleeve 36 and the commutator shaft 45. It will thus be seen that even if this governor is tampered with it requires a skilled Workman to again adjust the parts so that the motor will be operative.

governor which cannot be tampered with, and especially a governor which is inclosed. in a' sealed housing, is advantageous where inexperienced and irresponsible operators are employed for operating the engine, when used in connection with a motor veh-icle, and also where the municipal laws require that vehicles operate below a given speed limit.

It is obvious that variouschanges may be made in the details of construction Without departing from the spirit of this invention.
