Toall whom it may concern; t

Be it knownthat I, EDWARD L. Sunny, a

citizen of the United States, and a resident of Wa r ry, n hecounty of ew av n and State of Connecticut, have invented a new and Improved Engine, of which the fol- My invention relates more especially to. the class of engines known as explosive, or gas engines, in which gas is admitted to they cylinder and then expanded as by exploding with an electric spark, the force of the ex: plosion r ng e piston- Tlie object of my invention is toprovide a device of this class-in, which the full benefits of -,the force of the explosion may be obtained; and a further object of the invention istO; Provide a device in which th QITCe generated by the explosion shall be gradually communipated to the driven mechanism. One form -of device in the use of which these objects may be attained is illustrated in the accompanying drawings, in Which-7'" @Figure 1 isa view in central longitudinal section through the left hand cylinder of an en n e o y ng my n t n; the t asfseen in Fig. 5. 2 is a bottom view otthe engine, the pistons beingshown in a position reversed troin that shown in Fig. 1.

Inlets doommunicate with one end of each of the cyllnd'ers, these inletsextending from. a carbureter, common to this type. of engine, by means of gas and air. is supplied. to the chamber 6, ineach of the cylinders. Thecarbureter hasnot been shown in. thedlrawin s as its. locai tion and function will be readi y understood by those skilled in the art. nals 7, connected with any suitable source of electric energy, are located in each of the ;cyl;J;nders as a means for exploding the charge, the spark tonobtaining this result be.- ing obtained in any well known manner com mon to devices oii this. class. An air inlet 7 communicates with each of the cylinders on that side of, the piston in which the explo- {sion takes place, and this air inlet may be the cylinder. These valves are preferably located on the same valve shaft and occupy the relative P sitions illustrated in Figs. 3

,cylinder during the moveinent of, its piston. {under the force. of explosion. The valve Eshaft '12, to which the

valves

10 and 11 are connected, is of cylindrical form and has its. gpeater part practically of the same size as t e valves, as shown, indotted outlines in 5 Figs. 1 and 2 of the drawing, that portion of Ethe shaft forming the. valves having ports }10" and 11, ascl early shown in Figs. 3 and 4 of the drawing."

Itwill be. no erstood, of course, that the control the supply of airand of gas may a be. regulated'byasingle valve having pas :sages for the flow of air and gas. These vnueans tor controll ng said flow are so arranged that after the explosive charge is delivered from the carbureter through the. inlet 5 into the gcylinder, and before the spark is created tocause explosion. in that .i h ed ro s ex en menitcylinder, the' valve shaft rotates sufliciently ably. packed and each,- df the pistons maybe and 4, that is, bothvalvesare'OPBned to. each- W1res or termi-.

. connected with any suitable source 013 air.

located preferably ber a to close the inlet 5, which inlet is closed at the time the explosion takes place.

The admission of air from the tank 8 to the cylinder after the explosion takes place, and the opening of the port 29, hereinafter referred to, causes matter extraneous to the explosive charge to be driven out at the end of the inward stroke of each piston.

The valve shaft 12 extends through the end of the valve casing and bears a bevel gear 13 in mesh with a bevel gear 14 suitably mounted on an extension from the cylinder head. A gas valve lever 15 is secured to the shaft of the car 14;, and each end of the lever extends into the path of movement of the piston rods 3. It will be understood, of course, that these piston rods move in opposition to each other, and the lever 15 is therefore timed in its operations to admit the explosive charge from the carbureter and air from the tank 8 at the proper time into each of the cylinders.

At the opposite end of each of the cylinders from that in which the explosive charge is admitted and exploded is located a motor, as herein shown, this including a turbine casing 16 in which a turbine 17 is mounted. A passage 18 leads from the chamber 19 in each of the cylinders to the interior of the turbine casing, preferably at the upper side thereof and in position to conduct a liquid against thebuckets 20 of the turbine.

A reservoir 21 is located underneath each of the turbine casings, and a pipe 22 extends its from each of the reservoirs to the chamber 19. A valve 23 controls the passages from each of the pipes 22 into the chambers 19, and these valves are operated as by means of a driving fluid valve lever 24 suitably connected to each of the valves. Small rotary pumps 25 are located appurtenant to the pipes 22, these pumps 25 being operated as by means of a' shaft 26 connected as by a belt 27 with a pulley on the shaft 28 of the turbine.

ln theoperation of the device thereservoirs 21 are filled with'a driving fluid, as oil, and this is introduced by the action of the pumps 25 into the chambers 19 of the cylinders. g 1

The operation of the device is as follows: The parts being. in the position shown in Figs. 2, 3 and 4 of the drawing, and the piston in the left handcylinder (the upper cylinder shown in 2) .having juststarted its inward movement, the valve 23 is im-' mediately closed as shown in Fig. 3, and before the piston in the left hand cylinder has 0 scarcely moved. The

valves

10 and 11 are in position to close the openings into the left hand cylinder. As the piston in the left hand cylinder travels inward the

valves

10 and 11. are rotated in a clockwise direction'as viewed from the right hand of Fig.

2. this causing the upper edge of the valve morass as seen-in Fig. 3 to move to theleft. This movement opens the passages 5 and 7 to the left hand cylinder permitting the explo-- sive charge to efiter, and as the piston reaches the extreme forward limit of its movement the air from thetank 8 is permitted to enter and blow out the extraneous matter ahead of the explosive charge. When the piston in the left hand cylinder has reached this limit of its inward movement the explosion take place in the right hand. cylinder efiecting the same operation of the parts with respect to that cylinder as above described e v It will be understood that the explosive mixture is treated in the carbureter in a manner well known to devices of this class. It will be obvious that the lever 24: may, if desired, be operated by-mechanism differently constructed from that herein shown, and I do not desireto limit myself to the details of construction in this respect;
