    Tippett's Improvements in the Construction and Working of Engines, as mentioned, they will present but a comparatively small surface to the water, and thereby make but little resistance to the way of the vessel when they are retracted preparatory to another protrusion. To farther explain and make more perfectly clear the nature and intent of 5 my before-described improvements, I have annexed Drawings of one of the methods in which my improved engine worked by steam and air or atmospheric pressure is arranged, and also of one of the methods in which my improved boiler or steam generator is formed, according to the foregoing descriptions thereof; and of these Drawings the following is an explanation corresponding 10 to the letters and cyphers of reference added to the various parts. Figure A is a representation of one of my improved engines worked by steam and air, or atmospheric pressure, in which N° 1 denotes the beam of the engine; N° 2, the larger cylinder, open at its top to the atmosphere; N° 3, the smaller closed cylinder; N° 4, the pipe of communication between the top of 15 the smaller cylinder and the bottom of the larger cylinder ; N° 5, the valve box at the upper end of the smaller cylinder; N 6, the valve box at the bottom of the same cylinder; N° 7, the valve box at the bottom of the larger or air cylinder; N09 8, 8, the eduction pipes from both cylinders to the condenser; N° 9, the condenser; N° 10, a pipe leading from the condenser to the air 20 pump ; N° 11, a valve in said pipe opening towards the air pump; N° 12, the air pump; N° 13, the pump rod of the air pump; N° 14, the plug rod by which the gear or apparatus for working the valves is moved; N° 15, the orifice for the steam pipe that communicates with the boiler; N° 16, the head of the beam to which a connecting rod is to be attached for turning a fly wheel 25 to5work machinery, or for working pumps for raising water from mines or other depths and N0917, 17, the piston rods. Figure B represents the side of my improved boiler, in which N° 1 denotes the semi-cylindrical steam generator ; N° 3, the cylindrical boiler; Nos 4, 4, 4, 4, the vertical pipes which connect the cylindrical boiler with the semi-cylindrical 30 steam generator; N° 5, the preparatory or feeding boiler; N° 6, the pipe that connects the preparatory boiler with the cylindrical boiler; N 7, the feeding pipe of the preparatory boiler; N° 8, the man passage in the boiler, N° 9, the safety valve; N° 10, part of the pipe that leads to the engine. Figure C is a representation of the front end of the boiler, in which N 1 35 denotes the end of the semi-cylindrical steam generator; N° 2, the fire tube that contains the fire-place and ash receptacle; and Nos 4, 4, 4, the vertical tubes which connect the cylindrical boiler with the semi-cylindrical steam generator.
