To all whomit maycamem:
Be it known that I,.-EUeizNnonnAN, a citi- -zen of the Republic of France, :residingat Paris, France, have .invented certain new 6 and useful Improvemen'tsin Generators of Electric Current; and I .do hereby declare the followingto be a full,-clear, and exact description of'the invention-such as will enable others skilled in the art to which it 10 appertains to make and nsethe same.
- ,l'wThis' invention relates to generators of electric current and particularly rto a -reci1')- rec'ating engine in which current fis gener- F-ated directly by "the reciprocationfief a mOVv.

:The inventionis particularly us I ngthe .expansionof gases with external workas-in liquefaction systems,;although it is not,
ited to such use. In liquefaction systems wherein refrigeration is developed by expansion of gases in engines, it has been usual to employ reciprocating engines connected to rotary current generators which supply .25 the load and cause the expanding gas to do work. This arrangement involves a coinplication of apparatus and losses incidental to the multiplicity of moving parts.
It is the object of the present invention to avoid the disadvantages of apparatus heretofore used and to provide a 'simple and selfcontained generator in which the load is applied directl to the moving piston.
Further o jects and advantages of the invention will be apparent asit is better understood by reference to the following speci- ---fication and accompanyingdra g which illustrates diagrammatlcally; a form of expension engine which is adapted to accom- 40 plish the desired result. 7
In the application of the invention an expansion cylinder is employed with .suitable inlets and outlets forthe gas which may be controlled by valves which permit adjust- 4 ment of the cut-ofl. The cylinder and valve mechanism may be such as are employed on ordinary expansion engines. The details of the valve mechanism orm no part of the present invention and can be supplied 30 readily by anyone who is familiar with the structure and operation of expansion engines. The engine hereinafter described difi'ers from others in that the piston is not connected extern y of the engine and i Qiinerely floats in the cylinder, being moved :to and fro by the expansion of the gas as it is admitted and exhausted under control of the valve mechanism. The inner wall of the piston, which is hollow, consists of soft -irongin which a flux is set up under the excitation ,of an electric current. The piston is; therefore an armature. A stationary .plunger is supported at one end on the cylinderihead and projects into the hollow piston. plunger h as a non-magnetic core and a suracelayer ofsoft'iron. it also carries the *field windingsi whereby the flux is set up in f; the armature and the windings in which ouris generated-as the piston or armature Linpves'grelatiyeflyj tothe plunger. Suitable f-currentlleads areprov'ided to supply the exciting-current andto deliver the current generated-by the engine.
The-.:excitin g current may be obtained froiii' any suitable source such as line, storage batteries, etc., or even through a current rectifier shunted across the circuit in which current i's induced by the operation of the engine. The current induced is alternating with a .period which is a function of the number of poles and-the velocity of piston displacement. current may be utilized, or it may be caused to pass through a suit- --ablere'sistance where the only purpose is to provide. a loadg for the engine.
Referring td'ithe drawing, A indicates the expansion engine which may be of usual construction, having passages X through which the gas is admitted and exhausted under control of the valves (not shown). A piston H is adapted to move to and fro in the cylinder. The piston has a coaxial recess extending substantially throughout its length, and in the recess lamellae B of soft iron are supported, the inner surface of the piston being thus provided with notches and annular poles. These poles project radially into the central space of the piston.
A plunger P is securely mounted on the headof the cylinder and substantially fills the central space in the piston when the latter is at one end of its stroke. The
' plunger consists of .a non-magnetic core C upon which soft iron lamellae D are mounted, the lamellae forming notches and poles corresponding to those on the interior surface of the piston.
An insulated conductor E, of copper, for
example, is *WOllIld in thmgreeves; the -direction of wimlingalternatesliinthe adjacent grooves so as to produce consecutive poles of oppositesign when, the conductor is ener- Alternating current in the conductor: F formmg the router coils ot the plunger, and this current may be utilized as desired. By the application of the invention the difficulties met. in maintaining the operating parts =0f :engines and rotary generators, particularly when these are relatively sin-alhis avoided --'by' the elimination of the major portion of 'rhe apparatus heretofore considered to be necessary in such installations. The efii- -ciency of the apparatus .isxgaeatly increased because losses'fromidriction are reduced to a min mum.
Marous changes mayhermade in the form and. details Eiofaarrlmgement: of the parts without departing from the invention or sacrificing the adyantages.
