- To all whom it may concern:

Be it known that I, HARRY M. CHAMBR, residing at Lansing, county of Ingham, State vof Michigan, have inventedcertain new and useful .Improvements in Governors -for Explosion- Eng1nes,

o f which the following is a specificatlon. l v

This invention relates to 4improvements 1n Agovernors for explosion engines.

The objects of this invention are, first, to provider an improved governor mechanism for explosion engines having a-plurality of cylinders by which, when the speed ofthe engine exceeds a redetermined rate, the chargingL ofthe engine is automatically prevented, thereby preventing anexplosion and thereby controlling the speed. Second, to provide an improved governor mechanism or explosion engines in which the sparking is properly timed'and one in Which the electrical connections forlthe igniter mechanism. are disconnected when the' speed of the engine exceeds a predetermined rate.

AFurther objects, and objects relating to de tails of construction, will definitely appear from the detailed description to follow.

I accomplish the objects Vof my invention by the devices and means described in the following specification.

The invention is clearly deiined and pointedput in theclaims.

' A structure embodying the features of my invention is clearly illustrated in the accomipanying drawing, forming a part of this specifica-tion, in which,

Figure 1 is a detail plan of a structure embodylng the features of my invention, proportions being broken away to better show the relation of the parts. F ig. 2 is a detail enlarged Vvertical section, taken on r a line corresponding to line 12-"2 of'Fig. l. Fi 3 A is an enlarged detail plan ofthe in ner en of one of ,the levers 14, parts being broken away to better show the arrangement oftheparts. Fig. 4 4is a detail side elevation thereof.

'Fig'. 5 is an 4enlarged detail 'side elevationof the support and a justing means for the contact members 28. Figol is' a detail view, partially in .longitudinal section, vtaken on av line corresponding to line 6--6 -of Fig.' 5. Fig. 7 is a detail section taken onaline corresponding to line 7 7 of Fig. 2, showin details of construction. Fig. 8 is a detai l section taken on a line corresponding to line 8-8 ofFig. A

`In the drawing, the sectional views are taken looking in the fdirection of the little arrows at theends of the section lines, and similar numerals of reference refer to sin1ilar parts throughout the several views.

Referring to the drawing, 1 represents the lengine base and the crank shaft casing thereof; 2 lthe engine cylinders; and 3 the crank shaft'.4 Arranged, one at each side of the crank shaft, is a pair of cam shafts 4, having valve-actuating cams thereon, the cams being provided with drops or depressions 5Y on each side thereof, the object of which'will definitely appear later. Exhaust -by the push rods o r plungers, Y, which are arranged to engage the valve stems 10. The plungers 7 are lprovided with rollers 6, adapted to travel on the cams'.. The plun gers Aare provided at their outer ends with laterally projecting arms 11 on which the valve stems rest. he cam shafts 4 are connected, to the crank shaft by gears 12 a'nd 13, the gears 13 being arranged on the cam shafts and the gear 12 on the crank shaft. These gears are preferably proportioned two to one so that thecam shafts are driven at half the speed of the crank shaftl I A pair of levers 14, having inner yielding pivoted Aat 15 and are provided with latch ...blocks 29 at their outer. ends, adapted'to engage the catches 9 on the valve-actuating plungers 7. The yielding sections are securedlto th'e pivoted sections by pivots 15. TheV bolts -17 are adjustably secured to the inner end of the pivoted sections and 'are loosely arranged through the lever sections ,16. i

-Th'e 'coiled springs-18, arrangedon the bolts 17, hold the section 16 yieldingly in position. The'inner ends of the levers are held normally outward by the springs 19.

adapted to be controlled' by the governor ufeights 2l, the governor weights being pivoted at 22 on suitable arms provided therefor on the {1y-Wheel hub. then the speed of the engine exceeds a predetermined rate, the collarA is drawn outwardly, thereby releasing the levers sot-hat their outer ends sections 16, is provided. The levers 14 are On the crankshaft is a collar 20, which is lesy 30 le`ased successively.

1 0- portions of the levers 14, and as soon as the.

valve-actuating plungers are shifted .to release the latch blocks 9, the levers 14 are thrown out of their engaging position. The levers 14 are adjusted so that the catch '15 blocks 29 may be engaged with the blocks 9 at. the same time.l The adjustment of the levers 14 is secured by means of the bolt 17 which is held in its adjusted position by suitable lock nuts, the collars V17 coacting 20 therewith. This adjustment is of advantage, as, for instance, if the inner end of one of the levers `should be worn morez than the other by the governor collar 20, the other the wear.- A

It is evident that as the plungers are actuated alternately both the levers are not freed at' the same time. The yielding portion of the levers, however, permits their being re- Were it not for this yielding feature of the lever, both would be forced out vof engagement with the valve-l lactuating plungers at the same time, thereby releasing one or the other of them prematurely.

In order' to properly time the sparking, I provide the valve-actuating plungers with contact members '8, which are adapted to -enga e the relatively fixed spring contact 40 mem ers 28 as the plungers reciprocate. The contact members 28 are carried by the blocks 2,4 slidably mounted in suitable ways provi-ded therefor in the bracket 23.v

'At the inner ends of the blocks 24 is a slide 27, having a V-shaped portion arranged between the ends of the `blocks and having converging` ribs 30 arranged in suitable grooves provided therefor in the ends of the blocks. By adjusting this slide the blocks are drawn in or pushed out, thereby changing the position of the spring contact vmembers 28, so that they are engaged earlier or later in the stroke of the plunger, as desired. This arrangement enables the exact timing of the sparking, the sparkin mechanism being of the jump-spark class, which is well lunderstoodl and not here illustrated.

The slide27 is operated by the lever 26, which is'provided with a suitable segment 25.' When the ,lever is raised to its highest' oint so as to draw the contact members 28 1n\vardlythey are engaged' by the Contact members' on the valve-actuating plungers vl,very late in the stroke, thus causing a very late sparking, so that there is practically no ping the engine.

chance for a kick back. When the engine is started, the lever is forced downwardly, thereby moving out the contact members 28 to the desired point. When the lever 26 is in its outer position, the switch member 26 70 carried thereby is thrown out ofcontact with the segment. 25 thereby breaking the elec-l Y trieal connections andas a consequence stop- The structure by which this is accomplished is clearly illustrated in Figs. 2, 7 and 8.

It will be apparent that, when the exhaust valves are locked or held open, the charging of the engine is prevented, so that no charge is taken into the engine when running above a predetermined rate. This, ofcourse, prevents waste of fuel, Another-advantage isf that, as the engine runs when the valve is held open, the cool air passing into. and out of the cylinders cools the svame,`and also effectively cools. the valve. By adjusting the t tension springs 30,'in the governor, the speed of the engine can be nicely regulated.

It is apparent that when the valve-actuy ating plungers are not operated the igniter mechanism is not operated, so that the elec-` trical supply isnot needlessly exhausted.

'l have illustrated and vdescribed my iniproved '.governor mechanismV for explosion engines indetail in the formpreferred by nie on account of structural simplicity and effectiveness in use.` I am, however, aware that it is capable of considerable variation in structural detail withoutdepar'ting from my invention, and I desire to be' understood as 10o claiming the same specifically, as illustrated, as well as broadly.
