The machine in question con« sists of a frame mounted upon four wheels; this frame supports at each end two semicircular cylinders, similar to a (Q) retort. Between the cylinders there is a rod. having a piston at each end. made to fit the cylinders; this rod is actuated by a lever and ratchet wheels, so as to force the piston alternately into one or other of the cylinders, the motion of the lever being similar to that of pumping or working a fire engine. I'hc cylinders arc mounted upon an axis, or trunions, so as to be capable of being moved from a horizontal to a Tcriical position. The object of this is that, during tlie operation of forcing or expressing the clay from one cylinder, >vhich through dies, and which cylinder is in a horizontal position. The other cylinder may be placed in a vertical position, for the purpose of beinjj re-filled wiih clay ; and in this manner the cylinders are alternately filletl with clay, which is forced, in the manner described, though suitably formed for the purpose i>f making bricks, tiles, or pipes. ^RIC RAILWAYS. William Prosser, jun. of Pimlieo, and BRrrrr, of Hanover-square, for '• Improvements in railways, and propelling railway carriages^—Granted December 18,18M; Enrolled June 18, 1815. We have giien two drawings of this invention, which, with the following descriptiun, will be sufTicieni for must of our readers to judge of its ori- gmalily. Figs. I and 2 show sections of the valves and portions of the upper part of the tubes. The mode of propelling is the same as that pro- posed by Mr. Pinktis, in the specification of his last patent, as will be here- after described. In fig. 1,
