pump 1 rovide improved means whereby the peso one is drawn from s tank below mixed with an and introduced into the cyl- Imlcr by the suction of the engine-piston alone without the aid of a pump; end'I will now describe the devices eznpieyed'for this hegesolene tank or reservoir I preferably form within the en ine-hase a, as shown in Fig. 4, and to said base I'ettach a cesin hevinge mixing-chamber therein, which preferably provide with a. web, forming the some into portions t and h with 9211 opening I) between them. A gesolene-supply pipe 1) extends from a point near the bottom of the supply-tank through a, perforation in the base a and said casing through the portion 5 end opening is and terminates in the portion 1: above said opening. Said pipe is preferably, although not necessarily, provided at its lower end with any suitable'forrn of valve to retain the gesolcne that has been drawn into the pipe. The opening I) is of. greater said pi e is providod with perforations Z32, prefers )ly in that portion w IOIB it extends through the o )Blllllg b, as shown.

Any suitable valve may he used to cut oil the gssolene-sup iy; but I have shown a. rod b, with s, hand e b at its 11 per end and screw-threaded at its lower end to be screwed into the upper screw-threaded end of the pipe until it passes the perforations b, to cut off the gesolene-supply. I also referebl employ e disk 6?, screwthre ed on t escrow-threaded end of the 7 rod ti'se asto be adjustable in'its relation to thee 'enin'g t and the perforations 6*, said Fdisk sing preferably concave in form with thee'oncave side facing said opening.

I The sir-supply is introduced through an 1e chamber'b. I provide 9. valve for this inlet, and any 'suiteiie valve maybe em- 7 7 ey s that will resist the initial in: ulse of the piston-suction; but I have s own a. hinged" velve'llf. of suflicient weight, so that the first orifiitiii'ioipulse of the piston-suction will star-tend draw the esolene through the perforations B, the lifting of the valve and admission of sir immediately following.

' Instead of feeding the gesolene-snpplv by j The current passes through the contracted diameter than the diameter of the pipe, and

and adapted gravity or lifting it from a. lower level by a;

. let I) in an extension oi the casing forming at c to the engine-frame.

opening between the respective portions of said chamber, further lifting the gasolene and mixing with same, the disk spreading and aiding in thoroughly commingling the air and gasolene forming the explosive mixture, which is then drawn through a pipe b leading to the inlet a of the engine. A mixing-chamber without the central web and contracted opening will operate; but the construction shown is the priierred form.

A valve b, held in its closed position by a spring 1)", forms the inlet for the explosive mixture and is operated by piston-suction. A valve c, held in its closed osition by a spring 0, forms the exhaustva ve for the enme, and this valve is opened and controlled in the followin manner: A lever 0 pivoted intermediate 0 its ends to a post c, extending from the cylinder-head, contacts at one end with a head 0* on the exhaust valve spindle and at its other end is pivoted to the upper end of a lifting-bar 0 the lower end of w 'ch is pivoted to an arm 0 at a point intermediate of its ends. One end of said arm is pivoted at c to the engine-frame, and the other or free end is formed with a shoulder c, adapted to be engaged by a latch c", pivoted An arm 0, also pivbted at 0 has a transverse slot 0" in its upper end, through which a cap-screw 0 extendsinto the latch c to adjust the relative positions of said arm and latch, and a spring 0 holds said latch in contact-with said arm. The side plates a are securely bolted to the e inc-frame, and the crank-shaft d, which is riven in the usual manner, is journaled in the side lates. A short shaft (1 is journaled in the si e frames, as shown in Fig. 7, and at its inner end has a gear d fixed thereon ada ted to mesh with a pinion on the cranksha t, said pinion not being shown, and the outer end of said shaft has a disk (i rigidl attached thereto, said disk having a camon its outer side and a pin d projectin from its inner side. Said gears are prefersiil of the proportion of two to one, so that the disk d makes only one revolution to two revolutions of the crank-shaft. The cam d is adapted to contact with and raise the arm c, and thereby lift the bar a to open the exhaust-valve. The projection on the arm a, with which the cam contacts, is preferably in the form of a roller 0, journaled on said arm.

Within a plug e, adapted to fit in the perforation a of the cylinder-head and secured to said head, I journal a shaft e, havin an arm with a contacting him 6, and I a so fix to said plug a stud e aving a contactin point e. A crank-lever e is ri idly attac ed to the outer end of the shaft e and said shaft is further provided with a spring e to hold it from rocking. A rod e, spring-pressed by a spring e, is pivoted intermediate of its ends at e to the lifting-bar a, one end of said rod engaging the crank-lever e? and the other end being in the path of the pin d of the disk. When the cam d operates to lift the bar 0 to open the exhaust-valve, said bar carries the spring-pressed rod 6 out of the path of the pin C1 and when the bar 0 drops the exhaust closes and the spring-rod is in the path of the pin d The spring e being stronger than the spring e", the contact-points of the igniter are held apart; but when the pin (1 moves the spring-rod e to release its pressure .on the crank-lever e the s ring e brings the contacting points toget er, and just as they contact the pin (1 passes and releases the sprin rod, and the contacting points are quickFy thrown a art. Any suitable wiring may be employe for the current to the igniter.

To an arm of the fly-wheel f I pivot at f,

intermediate of its ends, an arm one end of which is hook-shaped and has a rojection (not shown) to contact with the ub of the wheel to limit the movement of said arm in one direction. The other end of said arm isprovided with a weight f 8 and a tensionspring f having a screw-threaded connection with another arm of said fly-wheel, a thumb-nut f being provided to adjust the tension of said sprin The adjustment is such that the hook-s aped end of the arm will normally engage and move the arm c against the tension of the spring 0, and the latch 0 being attached thereto will also move and release the arm 0", which will drop and bring the operating connections to the ex haust-valve and igniter into operative position; but when the supply is greater than the work re uired the hook-shaped end of the arm will e thrown inward, so that it will not contact with the arm a", and the latch a will hold theoperating connections for the exhaust-valve and igmter out of operative position until their operation is again required. The arm a is preferably rovided with a roller, with which the hoo -shaped end of the arm f 2 contacts.

It will be seen that I control the operation of the sup ly-valve b providing means to control and regulate t e exhaust-valve and that the valves and igniter remain in ino erative position until the demand u on t e engine requires their operation, an I further 1provide means for lifting the gasolenesup by the suction-stroke of the engine, an t at I also provide an improved construction for assembling the arts and radiating the heat from the cylin er.

Having thus described my invention, I claim- 1. In an explosive-engine, the combination with a supply-valve adapted to be operated by the piston-suction, of an exhaust'valve spring-pressed in its closed position, and an upon theot er, a pivoted arm having conneetions, including a lifting-bar; to said exhaust-valve, a rod pivoted intermediate of its ends on seid her, one end of which is adapted to engage and move said igniter and the other end extending in the path of said pin, a latch adapted to hold said urmout of the path of said cam, means adapted normaliy to release said latch and )ermit said arm to move into the path of said cam, said meens being furthered apted by the increased s eed of the engine to pass free of said hitch, su stentielly as specified.

2. In an explosiveengine, the combination with a supply-valve adapted to be'opemted by the piston-suction, of an exhaust-veive and an igniter, a pivoted arm having connections to said exhaust-valve end igniter, a disk hav ing a com to engage and move said arm to opemte the exhaust-valve, and a, pin to engage the connection to said igni ter, a latch adapted to hold said arm out of the path of said cam and n fly-wheel having an arm pivoted thereto adapted nornmliy to move said hitch to permit said iirst-nmned arm and connections to move into the path of some cam and in, said fly-wheel arm being Further adapted iiy the increased speed of the engine to pass free of said latch, substantially as specified.

3. In an expiosi\-'e-eng'ine, an exhaustvelve, a bar connected to said iveh e deyiees for operating said bar to open and lose'ss-id valve, on eieotrie igniter, the wontevting points of which iife "adapted to he swingpi'essed together, e spring'pressod rod piv otally connected to said exlmust-veive her adapted normally to hold said contesting points apart, means for operating said igniterrod independentlg of said exlmi'lst-vaive rod to permit said contacting mints to come together to produce a sparic, and means for hoiding said exlumst-vnlve liar, together with the connected igniter-rod, in inoperotive position, suhstmltieliy as and for the purpose specified. i

In testimony whereof I have hereunto set my hand this 23d day of March, A. i). 1903.
