(10.) In a furnace for chloridizing or for drying or roasting ores or other metalliferous materials, and (or) volatilising and separating their constituents, a rotating hearth having air- or gas-supply perforations or passages so arranged that they are approximately horizontal at that part upon which the material under treatment usually rests, in combination with a series of air- or gas-supply chambers or compartments, as d, arranged segmentally around the hearth, substantially as and for the purposes specified, and as illustrated in Fig. 8 of the drawings. (11.) In a furnace for chloridizing or for drying or roasting ores or other metalliferous materials, and (or) volatilising and separating their constituents, a series of adjustable hearths provided with chambers and perforations, each hearth capable of independent adjustment and motion, including that of a vibratory or shaking character, and projecting alternately from opposite sides of the interior of a tower, so that the ore or other material being fed from the top falls upon and passes over in succession each hearth, through which it is subjected to the action aforesaid of a current or currents of air and (or) gas, substantially as and for the purposes specified, and as illustrated in Fig. 9 of the drawings.

No. 13116.—30th October, 1900.—HARRY SHAW, of the Torpedo Corps, Wellington, New Zealand, Engineer. An improved knife-cleaning machine.*

Claims.—(1.) An endless oblong box, the bottom of which is provided with longitudinal slats or runners, and the side of which is pierced with a number of holes, in combination with a pair of boards fitting within the box and capable of sliding upon the slats or runners, the adjacent surfaces of such boards being covered with layers of felt or other suitable material, as and for the purposes set forth. (2.) In knife-cleaning machines, a pair of boards placed one above the other, the bottom one of which is provided with upwardly projecting ends between which the top board fits, and the adjacent surfaces of which are covered with layers of felt or other suitable material, such boards fitting and capable of sliding within an oblong endless box, as specified. (3.) The general arrangement, construction, and combination of parts in my improved knife-cleaning machine as described and explained, as illustrated in the drawings, and for the purposes set forth.

No. 13263.—20th December, 1900.—EDWARD WATERS, Jun., a member of the firm of Edward Waters and Son, Patent Agents, of 131, William Street, Melbourne, Victoria (nominee of the Linotype Company, Limited, of 188, Fleet Street, London, England, assignees of William Henry Lock and Philip Charles Lawless, both of 188, Fleet Street, London, aforesaid, Frank Cuttriss Dolby, of the Premier Cycle Works, Coventry, England, Richard Cornelius Elliott and Charles Holliwell, both of the Linotype Works, Broadheath, Chester, England). Improvements in linotype machines.

Extract from Specification.—The present invention relates to improvements in linotype machines, in late-news linotypes, and in means for holding the latter in working position in the respective printing-machine. The above-mentioned improvements in linotype machines have been invented for use in the Mergenthaler linotype machine described in the specification of Letters Patent No. 7001, although several of the parts thereof may be applied to other linotype machines.

[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. 13264.—20th December, 1900.—EDWARD WATERS, Jun., a member of the firm of Edward Waters and Son, Patent Agents, of 131, William Street, Melbourne, Victoria (nominee of the Linotype Company, Limited, of 188, Fleet Street, London, England, assignees of Isaiah Hall, formerly of 84, Manchester Road, Preston, Lancaster, England, but presently of the Mergenthaler Setz-Maschinen Fabrik, 17 and 18, Chaussee Strasse, Berlin, Germany). Improvements in the mould of linotype machines.

Extract from Specification.—The present invention relates to improvements in moulds for casting lines of types, or linotypes, as they are generally called, and which term is hereinafter used as including printing-bars for borders and the like. It also includes the improved linotypes made by the above-mentioned improvements, and the object of it is to do away with the necessity which at present exists in the case of any linotype machine of changing the mould or of altering the thickness of the mould-cavity in the mould for each change of fount. Thus, up to the present time, the thickness of a body of a linotype has always been in proportion to the height of the type, a nonpariel linotype being thicker than a ruby one, a brevier linotype thicker than a nonpariel, and so on. Further, a machine that has been working on brevier has a mould for a brevier body, and if the same machine is to be put on pica the brevier mould must be taken off, and a pica mould substituted for it; or, if the mould is in itself capable of adjustment for changes of fount, that dimension of it that corresponds with thickness of linotype must be set larger. Each change of fount, resulting, as just explained, in a thicker or a thinner linotype, has hitherto necessitated the substitution of a correspondingly thicker or thinner ejector-blade. A linotype mould stands in a horizontal position at the moment that a linotype is cast, with the matrices that constitute the mould for its printing-edge fitting up to the front of it, and the metal-pot and pump that supply the necessary molten metal fitting up to the back of it, they having been moved up to it for that purpose. After a linotype has been cast, the pot and pump are moved back again, and to prevent this rearward motion tending to draw the newly cast linotype out of the mould the latter has hitherto been tapered in the direction of its width, being narrower behind than in front. According to the present invention, no change of mould is necessitated by any change of fount, the improved mould being capable of having linotypes of any fount cast in it; no change of ejector-blade is necessary, because all the bodies are of the same thickness across their feet; and there is a special provision for preventing the linotypes being drawn backwards, that will allow of the sides of the mould being exactly parallel with each other.

Claims.—(1.) The described combination of mould-cavity and series of grooves. (2.) The described combination of mould-cavity, single groove communicating with the said cavity, and series of grooves. (3.) The described combination of mould-cavity, series of grooves, and ejector-blade. (4.) The described combination of mould-cavity, single groove communicating with the said cavity, series of grooves, and ejector-blade. (5.) The described combination of mould-cavity, series of grooves, ejector-blade, and adjustable trimming-knife. (6.) The described combination of mould-cavity, single groove communicating with the said cavity, series of grooves, ejector-blade, and adjustable trimming-knife. (7.) The described improved linotype capable of being trimmed down to the desired thickness.

Claims.—(1.) The described combination of a series of magazines, magazine-carriage, and bearing-surfaces for it to move on. (2.)
