` `Applicationfiled March 9, 189,4. Serial N o. 502,882.l (No model.)

To! all whom t-` may concern:

. -Bc it known that I, CHnRLEsQUAsT, a citizen of the United States,',residing 'at Marion, in the county of Marion and'State ofOhio, have invented certain newl and usefullIm' provements in Gas-Engines, of which the folf lowing is a specification, reference being had therein to the accompanying drawings. My engineis designed to operate under the Otto cycle, and it includes valvemechanism,

igniterlmechanism, a pumping mechanism, a'

governor, and a carbureter,the features of invention lyingin the special arrangement and combination of parts, as will be'hereinafter pointed out. Y

yIn the-.accompanying drawings, Figure 1 is lt side' view of the engine, partly in section, through suctionlvalve and vaporizer. Fig. 2 is an end View of engine, partly in section, through both the inlet and 4exhaust valves.' Fig. .3 is a sectional plan through valve-cham ber, showing water and Waste-heat jacket and Avtlso the igniter.` Fig. 4 is a section through the pump mechanism; Fig. 5 shows water connection for valve chest. Fig. 6 shows water-jacketof valve-chest. y

Bed-plate 96 carries in bearings 111 crankshaft 110, which carries on one end pulley 112 ind on the otherl liy-Wheel 116 and governoroulley 117. Said'bed-plate carries on posts 55 the cylinder, 'and this carries explosion- Bhest 4, which latter carries valve-chest 86. Crank-shaft 110 carries spur-gear 108, meshtng with spur-gear 94, journaled in the post 35, and these gears are of a relation as one to Lwo to each other in diameter. Gear 94 is keyed on shaft 118 in bearing 107 and carries n the end valve-cam 41 and igniter-cam 43. Valve-cam 41 engages with its periphery the roller 26 of lever 27 which is pivoted on oraeket 49 of pedestal 55. Said lever 27 carries above roller 2.6 valve-rod 20, which is guided in bearing 24 and screws in governorratch and combined-valve-.stem coupling 17, laving lock-nut 19.' Governor-catch carries n line with rod 2O valve-stem 15 and latter exhaust-valve 87.. On the valve-stem and netween governor-catch and valve-chest 86 s spring 101. Igniter-cam 43 has a high point l2 .to engage poin't 44 on igniter-'lever 40. lhe lever isconnected by. pivot 46 to igiiterfrod 13, vscrewed in spring-bushing 12 screw 36 to slide on a segment 37 to secure early'or. late explosion. The lever 27 carries, bya fulcrum 28, the lever 29, having aslot to receive a bolt 32, connected to a pump-rod 33 and to the lever by a thumb-screw 93, as

-i'n Fig. 4.v The lever 29 carries on one enda latch-lever 5l in hinge 52 with a handpiece 5 3. The latch-piece 51 carries a pin 50, which fits ,into a socket 51X'inl the -fulcrum-pin 92. The lever 29 has ahandle 54, which carries a spring 91, pressing against the handpiece 53 of the latch 5].. The pump-rod 33 is connected with the pump-piston 57`by the pivot 56, whchfiits in pump-cylinder 58, the latter being provided with suction and discharge valves. In the suction-pipe 61 is the shut-off valve 59. The pipe admits the oil or gas to the mixing o r vaporizing chamber 7l. The governor-frame 103 carries a spindle 22, balls 104, and pulley 105. The spindle 22 connects on one side by 81 with the valve-dog 18 and by the nger 23 with igniter-rod 3, the latter being guided in 23 by the eye 119. The rod 3 carries the collar 7, and between this and the guide 5 the spring 6 is located. The rod 3 is pivoted to the lever 2, which is fulcrumed at l and has an extension, 76 with peint 98. The Fulcrum 1 reaches through stuliing-box 83 into chamber 77, and there carries the said extension 76 to contact with the electrode 85, to which the circuit-Wire 84 is connected.

The engine workson the four-cyele systemthat is, it makes one explosion every two revolutions or every four strokes. As the crankshaft makesone revolution the valve, pump, andv igniter mechanism make a half-revolution and make an entire revolution during each two revolutions of the crank-shaft or to each four strokes of the piston.

As cam 41 i rotates with gear 94. the high part 47 .Win

raise the roller 26, lever 27, pump-lever 29, pump-rod 33, pumpspiston 57, also valve-rod 20, governor-catch 17, valve-stem 15, and exhaustvalve 87. This rising occurs every other revolution of the engine if not up to speed, thes'elaetions allowing the Waste products of combustion to escape and pumping a Ioo y sucks inthe explosive mixture p umped into4 the vaporizer, while the exhaust-valve closes;

' The exhaust takes placel when the piston moves toward the combustion-chamber and the exhaust-'valve4 is open, and the suction takes place as soon as the piston commencesto leave the combustion-chamber, and at thev same time the suction will .raise the suction-g Valve' 75. After the piston has reached the point farthest from the.combustion-chamber" vand returns, the suction-valve will fall and the compression begins, vas the gases cannot escape.` A s soon vas the piston has reacheda thenearestfpoint to thel combustion-chamber izo againcam 43 has turned and brought point 42 in contact with 44 of igniter-lever40 and raised same, also rod. 13, rod 3, compressed spring 6, and brought spark-lever .7 6 in con- 4 As lever 40 rises and points8`andr9 of igniter-rods touch, the-'n rod'will ,follow the motion of. rod 13, and as soon as spark-,lever 7 6' touches electric rod 85 the rod'3 will s top moving upward, and as i f 13 stillproceeds the spring 11 in bushing 12 `will compress-,

The moment of the sepaation of spark-lever 76 from velectric rod 85 fis regulated by moving lever 35 of eccentricv 38 onv segment 37, this releasing the highv points 42 and 44 sooner or later, which causes an earlier or later explosion. These explosions will continuev until the engine has reached the speed to which the governor is set. As soon as that speed is reached dog 18 will be shoved by governor-spindle 22 toward the valve-rod 20, and dog 18, engaging governor-catch 17, will prevent the exhaustvalve 87 from closing, this preventing the suction of new gases. At the same time igniter-rod 3 will be brought out of line with rod 9lthrough the governor moving 23 and guide 119. This prevents rod 9 from striking rod 8, and also the sparker will not operate or go through its mot-ions. Also lever 27 is held in a high lposition through governorcatch 17, and cam 41 will only raise it a little, just enough to allow the governor to withdraw the dog 18, this preventing the 'engine from sucking gases in improper time, as the suction only takes place right after the exhaust-valve closes. The governor-dog is fulide in bushing to allow the By the time ,piston 99 has st point of the combustionl chamber then the poi-nts 42l and 44` have 1 `55 crumedvright near valve-rod 20, taking alli strain away from the governor, so as not te interfere with the sensitiveness of same.

piston 57. This shows that the entire mech; -anisms are in rest as soon as the engine 1s up to speed and can 'only commence operation again at the proper time. In starting the engine 'a `fe w strokes of lever 29, carried by valve-lever 40, will send a charge of explosive into vaporizer 71. In handling lever 29 the hand Yof the operator will take hold of handpiece 54 and pressing 53 toward 54, thus' drawing pin 50 out of hole in fulcrum 92 and making lever 29 free, pivoted on fulcrum 28.,y Then a few strokes can be made. By releas ing. the handpieces 54 and 53 the pin 50 will be forced back again in fulcrum 92 and locks'y the lever 29 with lever 27 and couples same to make the motions as the latter does, this transmitting all motions of lever 27 through: rod- 33k upon pump-piston 57. The explosive.

pumped into chamber 71 runs over overflow- 95 65 upon-spreader 6G, having holes, and allow the explosiveif a liquid, to run through and over samey upon lower screens 64. As the engine sucks the air passes through openings 123 of hull 69 and passes along outside the Walls 0f chamber 70 and through the bottom of vaporizer 71 into screens 64 and 63, mixing with the explosive and passing through mixing-chamber 71, between screens 63 horizontally and screens 63 vertically, through. valve-seat 75 into chamber 77, where it is ignited at-the proper time. After exploding andexpanding the exhaust takes place. The waste products are expelled through chamber 70, passing past the walls of chamber 77 and the entire vaporizer 71, this heating the explosive as it is charged into the vaporizer and also the entire passage of same. As the exhaust passes on it reaches the larger part of 'chamber 70, right below the muffler 72, this allowing the gases to expand, giving off heat to the walls 86 and condensing. In passing through muffler 72 still more condensation takes place, and the expansion at the same time brings the waste products at an atmospheric pressure and temperature, this making a quiet exhaust. As the air enters openings 123, passes along the walls of muffler 72, absorbing heat from the same, and by passing along walls of 8G the air gets quite hot, this air passing through the bottom opening of the vaporizer and uniting with the heated explosive, vaporizesthe same quickly and perfectly. Passing on through the screens and chambers 71 and 121, the mixed gases are still heated, and by the time they reach the exploding-chamber they are very het and make an easy and high explosion. the weather, wind, rain, and snor-r from. af-

It will be noticed from Fig..1 that the igniter mechanism has two predetermined positions-one for later and the other for an earlier explosion-and that the adjustment by means of the cam, the lever, and segment is positive and accurate, it being only neces'- S-.ary to shift the lever from one position to lie otherin orderto adj ust the point of explo- :sion accurately. This adjustment is entirely independent of the adjustment in taking up 1the Wear, Which is done by the parts 12, 13, and 14.
