The steam-engine represented in our illustration is of an entirely novel form and possesses the peculiarity of a cylinder which revolves with the flywheel. It is claimed that the device is both efficient and desirable, while it is clearly compact and simple in construction.
A is the steam-cylinder, and B the fly-wheel. The steam chest is at C, and the exhaust extends through to D. E is the reversing lever, and F a cock for discharging condensation. The invention is so clearly shown that further detailed reference is deemed unnecessary.
The piston-rod, it will be noticed, is attached directly to the wrist pin, consequently all the friction of slides, crossheads, and connecting rods is done away with. The motion of the cylinder is produced by placing it at half-stroke on one side of the flywheel centre. The journals are cast solid upon the cylinder, and both the latter and the fly-wheel revolve upon their own axes. The valve is stationary and placed upon the exhaust pipe. The steam passes under the face of the valve, and then out of the pipe. The valve seat is movable, and, if necessary, both it and the valve can be removed for repairs by simply taking off the cap over the end of the chest. Within the latter the steam port is always exposed to the steam. The crank pin has an oscillating motion or about of an inch to a six inch stroke, and, it is claimed, is thus prevented from heating.
The lever is situated upon the exhaust pipe, and is attached to semi-circular leaves answering for a link. By turning it in one or the other direction, the engine can be reversed or started ahead; or by moving it up or down to the proper places, the lap of the valve can be altered while the engine is in motion.
The inventors, Messrs. Peter Black and Son, manufacturers, Hamilton, Ohio, state that they have had one of these machines in constant use for six years. Its cylinder is 3 x 6 in., and it makes 100 revolutions per minute, driving three printing presses. It has been ascertained by experiment that an engine with a cylinder 6 x 8 in. gives, by dynamometrical test, 14 horsepower, 55 lbs. of steam, and 120 revolutions. Attached to a 24 in. burr millstone, and a corn sheller grinding corn, a machine of the above dimensions under 55 lbs, of steam made 250 revolutions per minute, with 430 revolutions of the stone. The detailed results given are very satisfactory, indicating large economy of fuel, although the boiler employed was of a disadvantageous form.
