"vante-cuan mn covnasmc Meenemen son nxrnolsronnxemns,
To all vwhom 'it may concern:
Be it know-n that I, NO RMAN T. EARRING- Ton, `a citizen of the United States of America, residing at Lansing',` in the county of Ingham and State of Michigan, "have incentrifugal governor cooperating therewith.
' vTo this' end the invention consists in the construction of mechanism for simultaneously operating separate air and gas admission va, ves; further in the means by which the relative. movement of'said valves may be adjusted lto vary the ratio of air to gas, and further in the means whereby the amplitude of movement of both val'vesmaybe corres ondingly varied by an automatic governor, al as hereinafter set forth.
Y In the drawings-Fi re 1 is a side elevation. Fig. 2 is a top p an view.
A and B are valves for respectively controlling the admission of air and gas to the mixingchamber of an explosion e ine.
C/is the exhaust valve, and D a ever for operating said exhaust valve -through vthe medium of any-suitable mechanism, such as the rod E and cam F upon the constantly driven shaft G. j
In the operation of explosion engines the amount of air that is mixed with a given vol- -ume of gas to produce the proper explosive mixture depends upon the quality or richness ofthe gas, while the power depends upon the quantity of any given explosive mixture which isadmitted and compressed in the explosion chamber. One of the features ofmy invention is the construction by which adjustment foreither quality (that is, the proportion of air tov gas) or quantity may be readily effected independently of and Without interfering with each other. For ythis purpose, the air andgasadmission valves A and' B are operated through a' duplex mech- Speeication of Letters Patent. I Application mea January 2o, 190s. serial Nb. amas.
Y which operates'the exhaust valverand as shown, is of the following construction:
G is a segmental arm or arms projecting laterally from the lever, and H are radius rods adjustably connected to said segments at one end, and at their opposite ends connected to levers I at a point concentric. with.
the segments'in the neutraf position of the lever D. Each of the levers I is connected to lparallel the rock arms J which are arranged to a rock arm K extending o posite yfrom its fulcrum. vThe rock arms. are arranged to engage with the stems of the valves A and B respectively.
L is a bearing intermediate the rock arms Pateteaajprii 1e, l
J and K through which the movement of the former is -transmitted'to the ,latterf This bearing, whichl is preferably in the form of a v roll, is longitudinally adjustable in relation to therock arms, and the leverage exerted by the one arm upont-he other depends upon the position of this bearing L. The bea L are adjusted b links M attached `to roc arms N on a roc shaft O, the latterbeing preferably controlled by acentriug'al governor P connected to the, rock shaft 0 through the medium of the rock shaft Q and lever R. v
- In operation the cam-l1` will impart a rocking movement 4to the lever D, which will o perate the exhaust .valve C, and through t e medium. of segments G, radius' rods 'I-I, and
rock arms I will im arta rocking movement L rods H in the normal positionof the parts ar'ev concentric with the segments G andV adjustable thereon, they lmay be set in any positlon from a point in line with v'the fulcrum with the lever D, and where no movement will beim- ;parted't'o the rod to a oint at the extreme end of the radius arm Each of the rods II may be adjusted upon its segment independently of the other, and thus the amplitude of movement of each of the rock arms J ma be adjusted independently of the other,
' an to be in any-desired ratio thereto. The
'amplitude ofmovement ofthe valves A and B is," however, dependentnot onl upon vthe adjustment of the radius rods# but also 'I'pon the adjustment of the bearings L. einem, preferably directly from the lever liese bearings may be adjusted' into any polos sitioli Within iixed limits, but as they are simultaneously operated from a common rock shaft O the ratio of movement of the valves Will be the same as that o the rock arms J.
Thus the operation of the governor' which.
controls the rock shaft OA will merely vary the quantity of the explosive mixture admitted by the valves `into the engine, but will not change its proportions. On the other hand, an adjustment of the radius rods Iii will change the relative proportionA of air.
taneously seating and unseating said valves,-
means intermedlate said actuating mechanism and said valves for automatically and correspondingly varying the amplitude of movement of said valves and independent means for adjusting the relative degree of movement thereof.
2. In an explosion engine, the combinal tion with separate. air .and gas admission valves, of a valve operating mechanism for simultaneously seating and -unseating said valves, a lgovernor controlling said valve operating mechanism for correspondingly varying 'the amplitudefo'f movement of, said valves, and independent means of adjustment for varying the relative amplitudes of movement of sald valves. l j i.
