To ell 201mm it'may m 1 Be It known hat. I DA'nor Ainsnioa'rr-t W N 7 n4. w, a'sub ect 0L the lung of tzreat Britai rand lrelandpresiding at "iayniouth Engineeriii Works, Garnousti'e, in the county Of-" .Qra. r, Scotland, have invented new and usefulImprovements in 'i-Xpparatus. for Governing Operating Valves of which" the followingis 1a; specification.
This irivention'relates to a type of apparatus for governing and operating admission valvcsin suehh manner that the opening of a valve' wil l heinversely in propor- (ion to the speed of the engine of which the valve isa part.
Theinvention is applicable to the gas and air admission valves of an internal combus tlonen ine'or to any other valve of that type w ere it is desired to regulate the 'o'lume of fluid admitted to the cylinder.
In gas'en iines'zt-he rate of rotation of the crank slia-ft" determined by the quantity of explosive nurture admitted to the cyliuderiu a stated period,b y th erichhess of. the luixturc'and' by the amount, of compression of suc hnurture hefoiie ignition. 'lhe quan tity of miziture admitted is determined either by the hit; and rniss method, or by var in the amount re" uired for each ex- 39 plosion.
i apparatus; is applicable to the two methods "of. liegl'llating the supply of explosive mixture .fOlll'littIlZl'l combustion engil es, that is to say the quantity of explosive mixture can be varied tor each explosion, or the supply-Can entirely cut off for one or more reeiproeations of the piston.
In order that my invention and the rnai rnerflof utting the same into practice you bc .propel'ly llllgel'StQ Od I have hereunto appended aii explanatory sheet of drawing, in which the same reference n'u' merals 'are used to "indicate corresponding p te i j 'th' figur s ow v Figure-.1 is zi'part sectional elevationshowins th en a a r ngeme o t pperatus as applied toa gas engine. igl 2 is detail view of theearn roller lever'and Fi a view loo.l ing in the direction of the arrow AfFig. 2. i i In carrying out my invention I use a r0- tatory ball governor 1 which can cause a lever 2 to rise or fall, this lever being 'pivot ed at 21 to .the frame. Suspended at the free end of this lever is a rod 3 and on its lower end is adjustably fixed a setter block Specification of Letters Patent. Application filed Marc'n 29, 1912 Serial No. 686,984.

At the free end ofthis leve Y o is an adjustable spring plunger 11' whose adjustment can be effected by means oftlie nuts 12 and lil. In practice I find ihadvis able to use a second spring plunger 14 si'rni I lar in design to that first mentioned for. the mason that if only one. plunger heused I the spring 15 has to he so stiff thatit' may fracture whereas it two spring plun er s he i used the springs will be subjected to ess ini dividual. stress. Inffrontof the lever 9 -isa similar lever 16 pivoted to the eng-ine'at 23' its free end having on it a push knob .17 '75 which can he made to come against-the stem of the valve 18 and thus open 'thevalv e- 0n the faceof this lever 10 and" opposite the li of (he presser block 4 is air-inclined? he. 19, This plane may be iuclin'esl opposite the \\'l\0lt. path of the presse riblockas is.- shown in the drawings, "or for a part it upper end it may-he parallel to the .presser f guide 5 as-sh'ewn by the dotted linesl ig-a 8 5 The apparatus operates asfol-ldwsffl'lhe cam 7 when rotating movesforward the finger lever 9 next. it which ,znovernent is transmitted throughthe spring plungers ll and 1 1- to the finger lever 1.6 in front, 99 this lever in turn moving iorward and lift-1 ing the adrnission valve 18 ofi' -its seat.

tono load the hit and misssystem. Thiscombination is accomplished by the leverv 16 having a parallel face for a shortdistance down the inclined plane.
The action is as follows: At half load the setter block t is about the position Z. Im-
'mediately the setter block passes up beyond the point Z it is impossible for the lever 16 to move forward, thus shutting olf the from the engine. As the speed of the engine decreases the setter block falls below Z which allows the lever l6 to move sufiiciently forward as to open the valve18 wide enough to admit gas equal to approximately half engine power. 1
