A NEW DOMESTIC STEAM ENGINE. M. Fontaine has recently received a prize of $200 from the French Societe d'Encouragement for the invention of the domestic steam motor represented in the annexed engrav ings. The boiler of the device contains enough vyater to furnish some 42 foot pounds during the continuous period of work of a woman—some four or five hours ; and the design The device is composed of a generator—an engine told a gas furnace with automatic register. The engraving shows the exterior of the invention and also a sectional view. A is the body of the boiler in the lower side of which are twenty. four copper tubes B the upper ends of which enter the smoke box C. D is a sleeve through which the gases of combus tion descend to the chimney and E is a superheating tube which is closed at the bottom and extends down through the smoke box as shown. F is the feed water. tube closed by a screw plug indicated by dotted lines. Water cannot be put into the boiler except when there is no pressure of steam. At G dotted lines is a cock which draws off the steam when water is to be supplied through a pipe H and thence into the chimney. I is the flue connect ing with the sleeve D. J is the furnace composed of twen ty five Bunsen burners. The gas on leaving the meter goes to the upper part of the machine and enters at L. Here it meets a flexible tube M which resembles a bellows and forms a pressure regulator. N is a counterweight suspended to the tube M maintaining it at a leneth corresponding to the desired pressure. When the limit fixed is exceeded the tube elongates and checks the flow of gas by closing smaller the orifice L. K is the tube conducting the gas from this apparatus to the burners. Steam is taken from the super heating pipe by the tube 0 and is led to the slide valve P which communicates with the cylinder Q. R is the slide eccentric S the crank T the belt wheel U the exhaust pipe leading to the chininey V the manometer and W the sup porting legs of the appara
