PATENT IMPROVED INK DISTRIBUTOR.We have been much pleased with inspecting and witnessing the operation of Messrs. Sabbaton & Spence's Patent Ink Distribu tor, in book printing, at the office of Mr. Dean, Frankfort street, in this city. This machine, represented by the annexed plates, stands at the opposite side of the press to the workman, and receives its im, pulse from the rotary motion of the rounce, the shaft, A, of which is made long, passing to the end of the machine, where the pully, B, is fast; through the rim of this pully the end of the chord, C, is tied, and the other end, passing between a projection of iron, D, and a spring, is fastened to the loose pully, E, on the shaft of a wooden roller, as represented in figs. 1 and 2. This pully is attached by the same cord to pully G, on the end of the main shaft, that supports the pullies and weights in the centre of the frame, where a large loose pully, H, is connected by two catgut cords, II, passing in opposite directions to each end of the tail of the frame, K, that sup ports the composition roller, L. On the side of the loose pully, H, is a 236 Improved Rotary Steam-Engine.-Patent Machinery for making Window Sash, &c. that it can in truth represent objects, five Improved Rotary Steam Engine. By PHILO. LANCASTER, Pa. May 14, 1833. SIR,-The " Improved Rotary Steam Engine," of which drawings and a description are given in the third number of the American Mechanics' Magazine, is not the invention of " Mr. Mollery, of Oswego," to whom it is credited in that Journal, but of Phineas Davis, of York, in this state. An engine precisely similar in principle, and differing very little in construction, was made by Mr. Davis, and used as the moving power of the Steam Clover Mill, which was burnt in the borough of York thirteen or fourteen years ago. The inventor, in connection with other gentlemen, was subsequently engaged in constructing an engine on the same principle and plan, at the foundry of Rush and Muhlenburg, in Philadelphia. That en. gine was intended to be applied to propelling a boat in the Delaware; the enterprise however failed from some cause which is not distinctly remembered. There are many persons at York who would, from the draw. ings of Mr. Mollery's engine, at once recog. nise the identity of the machines. Two of Mr. M.'s engines, "of such dimensions that a man might easily carry one in each hand," are stated to propel a small vessel "of the size of a common canal boat," at the rate of "ten miles an hour," one engine being applied to each wheel. We will not question the correctness of this statement, but do not adopted by the New-Yorker, as seems suffi. cient to account for a more successful appli. cation, by him, of the principle to steamboat navigation, than was accomplished by the original inventor. I am, sir, yours, &c. PHILO. Description of Tichenor's Patent Machinery for making Window Sash, Pannel Doors, Window Blinds, and Pannel Work generally. Communicated by the Proprietors, for the American Mechanics' Magazine. Fig. 1 For making window sash, &c. the plank is sawed up into proper lengths and widths by the use of circular saws, which are set on proper frames, for that purpose, the opera tion and construction of which are too gene. rally known to need description. The planing is done on a wooden frame, fig. 1, made of timbers four by five inches square, six feet long, two feet wide, and three feet high; on the top of this frame, which is a smooth surface, made so by plank laid level with the top of the plates, stands a cir. cular cylinder, X, with cast steel knives or cutters, under which the stuff is passed to be planed while the cutters are in rapid motion. This cylinder may be raised or lowered at pleasure, to cut the thickness of the stuff to be planed. The small morticing is done in a small frame, fig. 2, two and a half feet perceive, from the drawings or description, high, and of sufficient strength to support any such variation, in the construction two upright standards or posts, b, in which Sub-Marine Boat. grooves are made for a slide to move; in the slide are two chisels, c, set for making the small mortice after boring. This is done by two treadles or levers, d, which are moved by the foot, one to press it down, and the other to raise it up, by means of a cord, e, passing over a pulley, which is attached to the slide, f, containing the chisels. The stuff to be morticed is kept in its place by the gages, gg, which are fastened by screws, hh. Fig. 3 represents a wooden frame of timber four inches by five inches square, eight feet long, six feet wide, and three feet high, to the top of the plates, with girts a sufficient height from the bottom to hang the drum. cranks, &c. on the frame. The following kind of work is done: the stuff, being planed, is taken to a small circular saw, i, set in motion on one end of the frame, and cut to an exact length by the aid of a wood slide gage, which can be set to any length, and can be screwed by set screws or keys. The next operation is tenoning: a small frame or gate, k, similar to a common saw gate, is fixed on the side of the large frame: in the top of the small frame are set two chisels, y, of sufficient length for tenoning small stuff; there are two saws, 1, hung in the same gate or frame, for tenoning larger stuff for doors, &c. one of which can be used for dove-tailing, with proper gages. In the same gate or frame is hung an instrument, called a coper, m, which is constructed of a flat piece of steel, secured on just far enough forward to serve as a gage for cutting the coping sufficient deep to form a correct fit to the moulding of the sash. The gate, or small frame, is hung within two perpendicular posts, nn, screwed on the side of the main frame, on which posts are fastened two bars of round iron, polished, and fitted for the gate to slide on; immediately under this gate, and 237 on the lower girts of the main frame, hangs an eccentric wheel, o, to which a pitman, p, is attached, which connects with the gate or frame in which the saws, chisels and coper, hang, and when put in quick motion by a strap or gearing is a very expeditious mode of making tenons, &c. This is done by passing the stuff along by the wooden gage, q, under the chisels, y, or up to the saws, 1, as fast as they cut clear; a screw gage is fixed to regulate the length of the tenons; when large tenons are made by the saws, the shoulders are cut by a small circular saw, i, hung for that purpose at one end of the main frame, over which the stuff is passed by a wooden gage, so as to gage it just deep enough, and moveable at pleasure. The boring is done by a spoon-bill bit fitted in a small arbor, r, set in motion at either side of the main frame, and is kept in its place by slide gages. The morticing is done on the opposite side of the main frame from the tenoning, by chisels, s, set in a similar frame and driven by a crank; the chisels are set transversely or crosswise, in order to leave a relish as in a mortice made by hand; one or more holes are bored to start from. The stuff is kept true to its place by slides or gages. The morticing is completed by passing the stuff along under the chisels, the same as in tenoning; a gage, t, is hung out at each end to govern the exact length of the mortice. One of these machines has been in successful operation for upwards of six months at Ithaca, Tompkins county. One man and two boys make, on an average, twelve hundred lights, seven by nine and eight by ten window sash, per week with ease, making the cost of the labor, allowing liberal wages to the hands employed, less than one cent per light. The proprietors, Messrs. W. & J. Woodward, of Ithaca, will give any information on the subject, and offer to sell rights for large or small districts of country. These machines are about to be erected in the following counties: Courtlandt, Tioga, Steuben, Cayuga, Oneida, Jefferson, Genesee, and Orleans, SUB-MARINE BOAT.-In the course of last autumn, M. Villeroi, of Nantes, made a successful experiment at sea, off the island of Noirmoutier, with a locomotive sub-marine boat of an entirely novel construction. It is ten feet six inches in length, and three feet seven inches diameter in its greatest width. The machinery by which it is impelled is said to be a mechanical application of the forms and means with which nature has en tected and concealed him, and showed himself to the spectators amidst hearty cheers. It is obvious, from the success which attended this essay, that with the aid of M. Villeroi's ingenious machine, an individual may tra verse a considerable distance under water with the same velocity as a common boat, and after calculating the depth to which he should plunge according to the density of the water, post himself under a ship's side for a hostile or other purpose, cut their cables asunder without being liable to detection, or descend for the recovery of wrecked stores, &c. The inventor was accompanied by two assistants, neither of whom suffered any inconvenience during their hour's submersion. The boat is constructed of iron. RUTT'S PRINTING MACHINE, MADE BY NAPIER, (Hoe's Improvement.)-This machine is put in motion by hand labor; the engra. ving represents the carriage at the back part of the machine, with the form of type just after a sheet has been printed, and the lad at the back in the act of taking it away: the table or carriage then returns to the front of the machine, to receive the ink for the next impression, which is communicated from the ink receiver by several rollers, distributing the ink one from the other until it finally reaches the form upon the carriage by means of an elastic composition roller; in the mean time, another sheet is brought from the heap, sufficiently over the edge of the board (and not on the cylinder, as shown in the above cut,) to enable a range of grippers, that are fastened with springs upon the cylinder, to seize and convey it on the form as the carriage again passes under, when it receives the impression; and it is then delivered at the back of the machine as above. The carriage and cylinder are propelled by cogged wheels, as will be seen on reference to the cut-the former having a fly-wheel attached beneath it; and the inking apparatus is kept in motion by a cogged rail fastened on the carriage.
