EXPLOSIVEMENGlNE.

SPECIFICATION forming part of Letters Patent No. 662,718, dated November 27, 1900.

Application led August Z5, 1900.

T0 all whom it may concern:

Be itknown that I, OLIVER F. GOOD, a citizen of the United Statesresidingat Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Explosive-Engines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked l thereon, which form a part oli' this specification.

This invention relates to new and useful improvements in explosive-engines, and comprises a double-cylinder engine, the details of which will be hereinafter specified.

The object of the invention is to providea double-cylinder engine with as few valves as possible, thereby greatly simplifying the engine, making it less liable to be troubled with leakage, and providing altogether a more efficient and reliable engine.

In a detail description of my invention reference is made to the accompanying drawings, of which- Figure lis a side elevation of my improved engine. Fig. 2 is a top plan view. Fig. Sis a horizontal section through the cylinderhead, as shown in Fig. 4, the'section being taken on a line between the two leversL and L'. Fig. 4 is an elevation of the cylinderhead and valve-box. Fig. 5 is a section on the line az' of Fig. 4. Fig. 6 is a partial sectional elevation of the devices for regulating the admission of gas to the mixing-chamber. Fig. 7 is an end elevation of the gas-` valve box.

In a detail' description of my invention similar reference characters indicate` corresponding parts.

A A. designate the cylinder head or heads, with integral valve-box O and inclosed by water-jackets A'.

B B designate two parallel power-cylinders communicating with the compression-chambers in the head or heads, (see Fig. 3,) which chambers are divided by Walls B' B', which have a water-space B". The interior space within the valve-box O is separated into two chambers F and F', the former being the mixing-chamber and the latter being the ex- Semal No. 27,965. (No model.)

haust-chamber, said chambers being common to both cylinders. Walls O' provide seats for checkvalves D and D', valve D being the inlet-valve controlling the admission of the eX- plosive mixture, which consists of air and gas, from chamber F to the compressionchambers, and valve D' being an exhaustvalveA for both cylinders. The admission and exhaust take place through the inlet and eX- haust-port E.

R designates an escape-opening from the exhaust-chamber F'.

Gas is admitted to the mixing-chamber F through valve I-I, and air is admitted. to said chamber F through an opening I, having a pipe or other connection. (Not shown.) Ohamber F supplies both cylinders through valves .I and J', which open into the compression-chambers in the heads. One of said valves is held open during one revolution of the crank and the other is held open during the next revolution. These valves .I and J' allow an expulsion of the burned gases on every alternate instroke of the pistons and admit fresh air and gas on every alternate outstroke. The said valves control the communication between the port Eand the compression-chambers in the heads, port E being common to both valves, as shown. in Fig.

L and L', the former being fulcrumed at L" and lever L having its fulcrum at L"". Lever L is connected to an eccentric or cam rod M'. The lever L has a projection N, against which the lever L' makes contact when the throw of the eccentric is toward the crank. When the eccentric-rod M moves toward the crank-shaft, valve J' opens through the movement of lever L and valve .I opens when the lever L' is moved by the eccentric-rod M moving away from the crank-shaft. rPhe operation of the valves is reversed on each. operation of thelevers-that is to say, one valve opens while the other closes. The gas-valve H is operated by the levers L and L' through tappets O and O', which are rigidly attached to said levers. These tappets or plates O and O' have their contact edges provided with grooves a, which engage with tappets or plates q and q', the latter plates being attached to a slide t, which moves on a guide or post t', projected from a slide T. The slide T moves 3. These valves are operated through levers IOO in a dovetail groove l) in the side of the valvebox I-I ofthe gas-valve. The end of the slide T projects at right angles in a position to engage the stem of said gas-valve H. Movement is imparted to the slide F through the levers L and L and the tappet-plates O and O. The said tappet-plates O and O engage with the projections or plates q and q upon each stroke of the eccentric toward and away from the crank, depending, of course, upon the positions of the plates qand q', which are controlled by a governor S. The said plates q and q are subject to movement at right angles to the movements of the slide T, and movement is imparted to them through the slide 't by a bell-crank, one arm c of which has a slot c', which receives a stud e on a side of the slide t, and the other arm e of said bell-crank is connected to the governor-rod d. The arms c and e are connected by a shai'tf. When the speed of the engine reaches a certain point above the desired speed, the slide t will move to a position that shifts the tappet-plates q and q' out of a position to be engaged by the tappet-plates O and O', and no gas will be admitted through the valve I-I at that time. If the speed of the engine diminishes or the engine for any reason shouldstop, the governor will cause the slide 't to drop to a position lower than the plane of the tappets O and O', and thus the said plates Q and q' will not be within reach of the tappets O and 0. It will be thus seen that there is no danger of the gas-valve remaining open when the engine stops at any point of the stroke.

Having described my invention, I claiml. In an explosive-engine, the combination with two power-cylinders, of a head having two separate compression-chainbers, an integral valve-box on said head and occupying a position midway of said head, a mixing-chamber, exhaust-chamber, and a passage E between said mixing-chamber and exhaustchamber, two valves controlling the communication between said mixing-chamber, exhaust-chamber, and passage, an inwardlyopening valve for each compression-chamber in the cylinder-head and controlling the admission of explosive mixture from the passage E to said compression-chambers, and means for operating said valves.
