"A Journeyman Mechanic's" Device

The gentleman, whose real name is unknown, but who styled himself "A Journeyman Mechanic," made an invention, an account of which appeared in "Mechanics' Magazine," in 1831. It was an attempted adaptation of the wellknown principles of Barker's Mill.

The inventor undoubtedly thought he had successfully solved the long sought problem of Self-Motive Power, and he benevolently and graciously offered to contribute his valuable invention to the world, having "no wish to profit by monopoly."

We cannot but contrast the plenary benevolence of his heart with the mechanical paucity of his head. He describes his invention with the following language and figure:

The inventor offers the accompanying sketch, with description of an Hydraulic Mover, for communicating power to machinery, and recently invented by him:—

A is a hollow cylinder or pipe, forming the upright shaft of a mill on Barker's well-known and effective centrifugal principle.

B B, the lateral pipes from ditto; a a, the jets of water, whose centrifugal force gives the motion.

C, beam to support the machinery, built at each end into the wall D D.

E E, two cog-wheels to communicate the motion to

P, the rod of a pump (on Shalder's principle), which derives its supply from the well into which the water from the pipes is conducted, which it raises to


H, a cistern into which one end of a syphon, I I, is introduced, the other end of which is soldered with an air-tight joint into the top of pipe A, to which it thus supplies the water which is continually running from the pipes B B, producing a constant motion which may be given by carrying the horizontal rod F through the wall D, to machinery for any purpose. And, if the statement in the pamphlet on Hydrostatics, by the Society for the Diffusion of Useful Knowledge, as to the effect of Barker's Centrifugal Mill, be correct, the power gained must be very great.

The advantages of the invention are obvious. The whole of the machinery for a large factory may be contained underground, which, indeed, will be the most desirable situation for it, and valuable room will thus be saved; the expense of erection will not be great; and the saving in coals, &c., necessary for a steam-engine of the like powers, will be immense. I might, perhaps, have secured much benefit to myself by taking out a patent for the discovery, but I have no wish to profit by monopoly. All I desire is, that it may be recollected that the machine was invented by one who is

A Journeyman Mechanic.
