CARBONIO-ACID OR OTHER GAS ENGINE.

SPECIFICATION forming part of Letters Patent No. 502,430, dated August 1, 1893.

Application tied February i4, "1893. serial no. 462.268. or@ modem y To all whom it may concern:

Be it known that we, ADAM BANNER, a subject of the German Emperor, and GEORGE ROTHENBCHER, acitizen of theUnited States, both residing in the city, county, and Stateof New York, have invented certain new and useful Improvements `in Carbonio-Acid or other Gas Engines; and we do hereby 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 accompanyingdrawings, andA to letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in carbonio acid and other gas engines and it consists in the construction and arrangement of inlet and outlet valves to the piston of the engine and inthe governor, whereby carbonio acid gas and similar gases may be utilized to actuate the engine.

1t consists also in the arrangement and combination of parts hereinafter described and claimed.

In the drawings Figure `1,` is a side elevation of the improved engine; Fig. 2 a plan View thereof; Fig. 3 a transverse section enlarged of the inlet and outlet valves and the piston of the engine. Fig. 4 is a vertical section of the valve. Fig. 5 is an enlarged plan view of the governor, and Fig. 6 an enlarged detail transverse section partly broken away, of the same.

In the drawings a represents the fiy wheel of the engine; b the steam cylinder and c the connecting rods between the crank of the ily wheel and the piston CZ which works in said cylinder b. The connection between the flywheel a and piston cZ and the construction of the parts do not differ from the arrangement and construction in ordinary engines.

Entering the head of cylinder Z9 are two pipes: the inlet pipe e and outlet or exhaust pipe j'. The inlet pipe e is provided with a rotary or oscillating spindle valve g operated by the handle h and the outlet pipe is also provided with a similar valve t' operated by the handle j. These valves are preferably arranged alongside each other so that they may readily be operated by the governor 7c in the manner hereinafter described.

The governor 7c consists of the shaft Z connected by suitable mechanism 'nt to the crank of the fly wheel a. In the drawings this mechanism consists of aseries of shafts and cranks so geared that therotary motion of the flywheel is communicated to the crank Z of the shaft Z of the governor, but it is manifest that any other suitable means of communication between. the iiy-wheel and the shaft Z may be used without departing from the spirit of our invention.

Between the ends of'shaft Z is keyed the drum n. Loosely sliding on said shaft Z is also placed the sleeve o carrying the arm p designed in its revolution to normally strike upon and operate the handle Zt of the inlet valve g. This sleeve o is provided at its opposite end with the collar q. Extending from the drum n and pivoted thereto are two elbow levers r r the free armss s of which are provided with adjustable weights s s' connected by a spiral spring t, all as shown in Figs. 5 and 6.

The short arms u of the elbow levers r r engage in suitable recesses n in the collar q of sleeve o keyed to the shaft Z. Near'one end thereof is the projecting cam arm o, designed, when said shaft is rotating to periodically strike Vagainst and operate the' handle j of outlet valve t'. c.

The operation is as follows: A drop of liquefied carbonio acid gas ora suitable volume of other gas passes through the inlet pipe e when the valve g is opened into the cylinder ZJ actuating the piston CZ which in turn through the connecting `rods c rotates the iiy-wheel. The fly-wheel in rotating actuates the shaft Z of the governor la through the connecting mechanism m. The shaftZ in rotating carries the arms p and 'v which arms are so placed on said shaft that they will alternately come in contact with and push over the handles 7L and j of the inlet and outlet valves g and t' respectively. When the shaft Zof the governor is rotated by the outward movement or expansion of the piston rZ through the fly wheel and connecting mechanism, the arm uwill, when the piston has traveled the entire length of the cylinder or the entire length of its stroke, strike against and throw over the handle j of the outlet valve 't' and thus open the outlet. Again at the inward stroke of the IOO Y theengine exceed a certainprescribed` speed piston, the arm p of the shaft Z of the governor will strike against and throw over the handle h of valve g and thus open the inlet to the cylinder. It is to be understood that normally the handles h and j of the valves are thrown by springs h into such a position that the valves are closed and the opening of these valves is controlled by the governor la through the arms p and fu. As already eX- plained the arm p operating the inlet valve is not carried by the shaft I of the governor but by the sliding sleeve o thereon. Should the governor 7c through the rapid revolution of its shaft l will either refuse to open the inlet valve g or will only open the same to a slight extent (by the contact of the curved ends of the handle h, and arm 29) thus reducing instantly the excess of speed. This is accomplished by the drum 0 and elbow levers r r which latter, 'when rotated rapidly by said drum tend to throw off at a'tangent the spring controlled weight arms s s', when the arms u operating in the recesses u of the sleeve 0 will slide the sleeve outward and thus throw the armp out of alignment or contact with the handle h of the inlet valve to a greater or less extent. When the speed slackens the springs tend to return the arms o" r and thereby the sleeve o and its armp to the normal position when the outlet valve willl be opened to its normal extent. It is obvious that any valve may be adapted to be controlled by the governor 7a although the form shown in the drawings -will suffice to illustrate the spirit of ourinvention.

Having thus described our invention, what we claim as new, and desire to secure byLetters Patent, is-

1. The combination of the cylinder, the piston, connecting rod and fly-wheel of an engine, with the inlet and outlet pipes arranged parallel to each other and entering the end of the cylinder, the inlet and outlet valves arranged alongside each other and provided with extending handles, and with the governor consisting of a shaft operated directly by the iy-wheel `and sleeve splined to said shaft and weighted elbow levers pivoted to said shaft and adapted to slide said sleeve on said shaft, said shaft and sleeve being adapted to operate respectively the outlet and inlet valves, substantially as described.

2. The combination of the cylinder b, pisV ton d, connecting rods c and fly-wheel a, with the shaft l, mechanism whereby the Iiy-wheel rotates said shaft, the drum fn., keyed to said shaft, elbow levers r r controlled by spring and pivoted to said drum, a sliding sleeve o splined to said shaft Z and adaptedv to be operated by said levers fr r, and aims o and p carried respectively by the shaft land sleeve o, and with the inlet pipe e, outlet pipe f, arranged parallel with each other and entering the ends of the cylinder, inlet valve g, outlet valve t', said inlet and outlet valves being provided with projecting spring controlled handles 7L and j respectively, all arranged so that when said sleeve oand shaft Z are rotated they will alternately operate said valves g and 't' by the arms v and p alternately engaging land throwing over the` handlesj and 7L respectively, substantially as described.

In testimony that we claim the foregoing we have hereunto set our hands this 13th day of December, 1892.
