forced longitudinally by means of a shifter S 32 through the knife-box and past the knife contained therein, which trims the other side of the linotype close to the printing-edge throughout its entire length. The linotype is then dropped into position to be engaged by a vibrating finger S 49, which assembles it with the linotypes previously cast in a galley S 48 in suitable order to be printed from. During this operation of the ejection and trimming of the linotype the elevator N has ascended to the upper portion of the machine, carrying with it the line of matrices and space-bars until they register exactly with the distributing-box. The line-shifter W then moves in to the right, carrying the line of matrices and space-bars into the distributing-box W 9, where the space bars are separated from the matrices by means hereafter to be described and returned to the space-bar magazine. The shifter W continues to move the matrices towards the distributor X, where they are engaged one by one and returned to their proper channels in their magazine B. In the meantime, the elevator N has descended to its original position, and the operation of the cam-shaft and parts connected therewith has been stopped automatically by means hereinafter to be described. It will be seen that the matrices and space-bars are returned to their proper magazines by a path different from that which they pursued during the course of assemblage, or, in other words, that the present invention retains what is termed in the art the circulating system. This feature enables the operator to begin the composition of a second line immediately after he has transferred the first line to the elevator, and to release the elevator so that it may descend to its operative position, because the further operation of justifying, ejecting, trimming, and distributing are entirely automatic.

[NOTE.—The number and length of the claims in this case preclude them from being printed, and the foregoing extract from the specification is inserted instead.]

No. 13879.—1st August, 1901.—JOHN FRANCIS O’ROURKE, of 53, West Eighty-fifth Street, Manhattan, New York, United States of America, Engineer. Improvements in subterranean or subaqueous dam or foundation construction.

Claims.—(1.) A plurality of caissons having removable and registering doors or wall-sections in adjacent walls, substantially as described. (2.) A plurality of caissons, having removable and registering doors or wall-sections in adjacent walls, and having their adjacent walls secured together close to said removable doors or wall-sections, substantially as described. (3.) A plurality of caissons, having each a roof, and having removable and registering doors or wall-sections in their adjacent walls below the roof-line, substantially as described. (4.) A plurality of caissons, having registering openings in adjacent walls, and a body of concrete or other material filling said caissons, and extending from one to the other through said registering openings, substantially as described. (5.) The combination, with a caisson formed of vertical timbers and horizontal beams, and having its uppermost horizontal beam set below the upper ends of the timbers, of a coffer-dam formed of vertical timbers and horizontal beams, and having its lowermost horizontal beam extended below the lower ends of the vertical timbers, whereby a male-and-female joint is formed between said caisson and coffer-dam, substantially as described. (6.) A plurality of caissons, having bevelled ends, with registering openings in the abutting ends, and a body of concrete or other material filling said caissons, and extending from one to the other through said registering openings, whereby the completed wall is self-supporting against external pressure, substantially as described. (7.) The method of building subterranean or subaqueous walls which consists in sinking successively to the desired depth a number of caissons abutting one against another, filling each caisson in succession with concrete or other material, leaving a space or well in such caisson adjacent to the next caisson, making an opening through the abutting walls from each caisson into the space or well left in the previously filled caisson, and filling such space or well from the next succeeding caisson, and such succeeding caisson in like manner, substantially as described. (8.) A subaqueous or subterranean foundation, comprising a series of sectional dams united to form a continuous dam about the space to be covered, and a filling of concrete or other material within such dam forming a solid foundation, substantially as described. (9.) The method of building foundations for piers in water or water-bearing strata which consists in sinking to the desired depth about the space to be covered by the pier a number of caissons, filling each caisson with concrete or other material to form a dam, and making the dam continuous from each caisson to the next, and filling in with concrete and other material the space enclosed by such continuous dam, substantially as described.

No. 13880.—1st August, 1901.—JOHN WARREN, of the Broken Hill Proprietary Block 10 Mine, New South Wales, Mining Manager. Improvements in electro-magnetic ore-separators.

Claims.—(1.) The described method of feeding comminuted ore or other material into a magnetic field consisting in the employment of a plain horizontally rotating disc, whereby regulated quantities of material are by the rotation of said disc gradually carried within the influence of a magnetic field constituted and adapted by the aid of another rotating separator disc and an electro-magnet to draw off a regular and continuous strip consisting of the more magnetic particles of the material to and over the edge of the lower or feed disc, substantially as described. (2.) In a magnetic ore-separator, the combination and arrangement of—(a) a plain horizontally rotating feed disc; (b) an electro-magnet whose pole-pieces are arranged and fixed so as to constitute a field of high magnetic influence across the portion of the feed disc covered by the ore or material under treatment; (c) a saucer-shaped separator disc rotating at preferably a higher speed than the feed disc between the magnet-poles and the feed disc; (d) means of adjusting vertically the proximity of the magnets, the separator disc, and the feed disc in relation to each other, substantially as described, and as illustrated by the drawings. (3.) In a magnetic ore-separator, the combination and arrangement of—(a) a plain horizontally rotating feed disc; (b) several electro-magnets, the poles of each of which are arranged and fixed so as to constitute a field of high magnetic influence across the portion of the feed disc covered by the ore or material under treatment; (c) several saucer-shaped discs rotating one under each magnet preferably at a higher speed than the feed disc; (d) means of adjusting vertically the proximity of the magnets, the separator discs, and the feed disc in relation to each other, substantially as described, and as illustrated by the drawings. (4.) The combination and arrangement of parts forming the improved electro-magnetic ore-separator substantially as described, and as illustrated in the drawings. (5.) The combination and arrangement of magnets and mechanism for securing a field of high magnetic influence of the kind described, and for the purposes set forth, and illustrated by the drawings.
