To all whom it may concern:

Be it known that I, ALFRED E. REMICK a citizen of the United States of Amerioa,'residing at Providence, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in EXi plosive-Gas Engines, of which the following is a specification.

Th'i "invention relates to explosive gas engines, and one of the principal objects of the ;same is to provide an oscillatory piston engine of simple construction which will operate efliciently as a portable motor or as a stationary engine.

plify the construction of engines of this character, render them more compact and to provide means whereby all the parts are readily accessible for repairs and renewals.

Still another object of the invention is to provide simple and efhcient means for lubricating the piston and the inner wall of the cylinder.

These and other objects can be attained by 5 means of the construction illustrated in the accompanying drawin in which: I

Figure 1 is a side e evation of a portable oscillating piston gas engine made in accord- L ance with my invention. Fig. 2 is a similar view looking at the opposite side or end of the cylinder, parts being omitted to better illustrate the valve operating mechanism. Fi 3 is a side elevation looking-into the cylin er,

one of the cylinder heads bein removed.

Fig. 4 is an elevation and partia section of the engine. Fig. 5 is a side elevation of one of the valve operating levers. Fig. 6 is a similar view ta en at right angles to Fig. 5. Fig. 7 is a detail view showing the relative arrangement of the two valve operating levers. Fig. 8- is a side elevation of the engine arranged as a stationary engine. a

Referringto'the drawings for a more particiilar description of my invention, the nu- 145- meral 1 designates the cylinder, 2 is oneof "the cylinder heads and 3 is the other cylinder head, said heads being secured to the cylin- 1 (161' by means of bolts 4, and the cylinder beinghollow to provide a water jacket or air 0 space 5 provided with a screw cap 6 for filling thephamber 5' with water or other cooling We -f Tliecylinder'l is mounted upon a suitable use 1. Secured to the inner wall of the y'jnder 1 at diametrically opposite points Another object of the invention is to simare the V-shaped abutments 7, 8, said abutment-s having a central partition 9, and inclined side walls, as shown more particularly in Fig. 3., An oscillatory piston comprising a tubularsleeve 10 is mounted to oscillate co between the cylinder heads 2 and 3, and is provided with suitable packing 11 to-form a tight joint in said cy inder heads. Connected to the sleeve 10 are the oppositely disposed pistons 11, 12, said pistons bein 5 provided with suitable packing 13, and oi ducts 14 extending through the istons 11 and 12 and communicating with t e bore of the sleeve 10, said bore forming an oil chamber 15. A suitable oil cup 16 is mounted on the sleeve 10 and communicates with the chamber 15 for feeding oil thereto. Oil ducts 17 extend across the ends'of the pistons 11 and 12 to carry oil from the duct-s 14 to the packing. The sleeve 10 is covered at one end by a suitable cap or head 18, and at the opposite end is provided with a cap carrying a lever 19 which is slotted at 20 for the attachment of a connecting rod 21, the lower end of which is pivotally connected at 22 to a crank 23 mounted on a shaft 24 carrying a pinion 25 which engages a gear wheel 26. mounted on a shaft 27. The shafts 24 and 27 are journaled in a bracket 28 formed on or secured to the base 1'. A fly wheel 29 is mounted onthe shaft 24. In the walls of the abutments 7 and 8 flaring valve seats 30,

31, 32, and 33 are provided and similar shaped valve heads 34 provided with valve stems 35 are operated to open and close by means of crank levers 36 pivoted at 37 in the cylinder head 3 and connected to the crank levers 36. On the outer side of the cylinder head 3 are links 38. For operatin the valves through the links 38 bars or lin ks 39 are provided, said bars or links, as shown in Fig. 5, being provided with lugs 40 and 41 designed to engage the links 38 and to move ,them in position -to open the valves 34. Springs 42 are connected at one end to the links 38 and at their 0 posite ends to the bars or links 39. The Ears or links 39 are provided with inwardly extending arms 43 carrying rollers 44 at their ends. On the shaft 27 a pair of cams 45 are fixed, said cams being adapted to engage the rollers 44-on the arms 43 to alternately lift and depress the bars 39 for opening and closing the ports or valve seats 30, 31, 32, 33 in the abutments.

The abutments 7 and 8 are provided with packing 46 to form a gastight joint between said abutments and the outer surface of the.

. Intake ports 47 a and 48* are provided in the cylinder head 2, said intake ports each having a spring seated check valve 47*, as shown more particularly in Fig. .4. Sparking plugs of any suitable construction are secured in toward the valve 31.

the openings 49 in the cylinder head 2.

The operation of my invention may be briefly described as follows: Gas is taken in through the intake opening 47 and is ignited between the'valve 30 and the piston 11 which forces the piston 11 downward toward the valve 34 and the piston 12 upward This movement of the piston draws in a charge of gas through intake valve 48 a} which serves to compress the charge taken in through intake opening 47 this charge being ignited as piston 12 is mov ing downward. This movement of the piston opens exhaust valve 30 letting out the spent gases and taking in a charge through.

intake valve 48, and so on alternately dur- 1 ing the operation of the engine.

From-the foregoing it will be obvious that 8 my invention is of simple construction; is compact; ready access may be had to all the to said cylinder and openings, V-shaped a utments within-said parts, and the engine may be used either as a portable or a stationary engine.

- Having, thus described the invention, what Iclaimis:- v

1.v In a gas engine, a cylinder, heads fitted rovided with central cylinder, a sleeve mounted in'said heads, pistons carried by said sleeve, valves in the walls I of the abutments, a pair of bars connected together and provided with lugs, links connected to said valves and to said bars, and cams for operating said bars.

2.-In a gas engine, the combination of a cylinder, hollow V-sha ed abutments therein having inclined wa ls, a sleeve mounted to oscillate in the cylinder heads, pistons carried by the sleeve, the walls of the abutments being provided with inlet and outlet ports, valves for opening and closing said inlet and outlet ports, links connected to said valves, bars for operating said links, said bars having lugs to engage said links, a shaft,

cams on said shaft for lifting said bars, and springs connected to said links and bars for returning said valves after each operation. In testimony whereof, I affix my signature in presence of two witnesses.
