The following inventions have been patented this week, as will be found by referring to our List of Claims : Machine FOR Cutting the Heads of Casks.A. D. Stewart, of Bennington, Vt., has invented an improvement in that class of machines for cutting cask heads in which circular concave saws are used. The inventilm consists in using in connection with a circular concave saw, and on the same mandrel, a cutter formed of two or more saws, arranged in a novel way, whereby the heaus are cut out from the stuff, imd a bevel cut on both sides of the heads at one operation, the work being performed in a vary perfect manner. Sole Cutter.By an arrangement of a cutting knifc in a proper frame, this inventor causes it to follow a pattern ; and with its aid any number of boot and shoe soles can be cut from leather or other ,material exactly according to a given pattern, by the mere turning of a crank. John Crawshaw, of Rochester, N. Y., is the inventor. Apparatus FOR Hanging up and Carry. ing off Paper-Hangings.Wall paper being printed in snch great lengths requires some system of laths over which the paper can be loosely thrown to dry. This invention comists in a certain arrangement of belts for carrying the laths, whereby, as the paper is formed into festoons, the sides of the festoons are prevented striking each other, and smearing, or otherwisc injuring, the wet impression or coating. It further consists in the application of !prings to the lath-feeding box, to allow laths of varying thicknesses to be used, and to permit laths that may be warped to pass through, and yet never to allow more than one lath at a time to pass out. The inventor is Theodore Vandeventer, of New Brunswick, N. J. Mode oF Casting Hingbs.This is an improvement in casting that kind of hinge in which a central pin is dispensed with, and a jointed connection formed between the two parts or leaves of the hinge by means of seats or projections at the ends of the knuckles of one leaf, a part of which fits in a corresponding recess in the ends of the knuckles of the other leaf, the joint being formed by casting one part in a mold partly formed by the other part, or in other words. casting one part with the other. The invention is designed to obviate the difficulty hitherto attending the free movement of the joint, and to dispense with the labor or finishing now requisite, in order to perfect the hinge when cast in the usual way. This is effected by casting the knuckles of such form that their inner halves will be portions of cylinders of less diameter than their outer halves, and thereby allow a space between the face side of each knuckle, and the edge of its adjoining leaf, so that a perfectly free moving joint is obtained when the hinge is cast, no extra labor or finishing be- J ing required. Conrad M. Lane, of Cincinnati, J: Ohio, is the inventor.
