No. 19663.—3rd July, 1905.—TOM SCOTT ANDERSON, of Royal Insurance Buildings, Sheffield, England, Consulting Engineer. Improvements in the method of and apparatus for the smelting of ores, ironsand, and the like, and its subsequent conversion into steel or other metals or alloys.

Claims.—(1.) The improved process of and apparatus for electrically smelting ores, ironsand, and the like, constructed, arranged, and operating as described. (2.) An electrical smelting-furnace provided with electrodes I¹ and I² acting in combination with electro-magnets K¹ and K², constructed and operating as described and substantially as shown. (3.) In an electrical smelting-furnace having the electrodes and electro-magnets claimed in claim 2, the use of a central electrode L, as described and shown. (4.) The general arrangement and construction of an electrical smelting-furnace for reducing ironsand, pulverised ores, and the like, characterized by the use of vertically adjustable electrodes which enter the furnace, and electro-magnets located in vertical line with the said electrodes below the floor of the furnace, as described and substantially as shown.

No. 19665.—3rd July, 1905.—SALO WOHLE, of 22, Great Russell Street, London, England, Chemist. An improved detergent for scouring wool.

Claims.—(1.) A detergent for scouring wool made from a decoction of a vegetable material yielding mucilage and saponin or an extract containing saponin, substantially as described. (2.) A detergent for scouring wool made substantially as described.

(Specification, 2s.)

No. 19666.—3rd July, 1905.—ROBERT CHARLES LOWRY, of General Delivery, Seattle, Washington, United States of America, Gentleman. Improvements in devices for magnetically increasing the adhesion between truck-wheels and the rails upon which they roll.

Extract from Specification.—Whatever construction is used it is desirable that the wheels and pole-pieces be held close together but not in actual contact, so that the magnetic lines of force induced by the passage of the electric current through the coil may meet with the least possible reluctance in completing the magnetic circuit. By maintaining a slight air-gap I prevent the friction which would be produced by actual contact between pole-piece and wheel. I am thus enabled to secure efficiency and simplicity in the device and avoid constructions which are liable to get out of order. For the efficient use of my invention a magnetizable axle is unnecessary, as the axle does not form a part of the magnetic circuit, and I aim at preventing the magnetic flux from reaching the axle and thereby being dissipated to any extent; and, further, I endeavour to pass the magnetic flux into the wheel as near as practicable to the tread of the latter, and thus insure its entry to the rail at the point of contact of the latter with the wheel. In my invention the magnet-core does not embrace the axle at any point, and thus I altogether avoid the disadvantage due to cutting-action of malleable iron or steel moving in contact with similar metal.

No. 19668.—3rd July, 1905.—MERGENTHALER LINOTYPE COMPANY, a corporation having their principal place of business at Tribune Building, 154, Nassau Street, New York, United States of America (assignees of Fred Eugene Bright, of 1814, Spring Garden Street, Philadelphia Pennsylvania, United States of America, Engineer). Improvement in linotype machines.

Extract from Specification.—The general operation of the machine is substantially as follows: The matrices A are released from the machine C through the operation of the escapement E, which are suitably connected to the finger-keys F. Similarly, the spacers B are released from the spacer-magazine G by an escapement connected to the spacer-key H. The matrices A pass through the delivery-chute D to the channel I, where they are assembled with

the spacers B in proper order to form the words of a line. The starting-lever U is then manipulated, and the matrices and spacers are transferred to the casting-position within the spacer-device J, where they are aligned, justified, and locked in position. The mold-frame K and pot L advance, and the slug Z is cast. The matrices are then unlocked, and the device J removes the spacers from the line and they are restored to the magazine G. The matrices are transferred to the elevator, which is moved along the bar N by the chain M, and carried to the top of the machine. The matrix-shifter moves them into position to engage the distributor-bar Q, along which they are carried by the chain P and restored to their proper channels in the magazine C. During these latter operations the mold-frame K turns outwardly, and the base of the slug is trimmed by the knife R. The ejector-blade S then moves the slug Z so that it projects slightly from the mold-slot, in which position it is trimmed on its upper and lower front edges by the knives T, T. The blade S then ejects the slug Z, which is received by the slug-assembling devices and delivered in proper position in the galley Y.

No. 19682.—5th July, 1905.—JOHN CHISHOLM, of Kalgoorlie, Western Australia, Metallurgist. Sluice-discharge construction of filter-presses.

Extract from Specification.—The improvements essentially consist in forming the underside of each hollow frame of the filter-press with an opening or port—for the downward discharge of the residue, such port being opened or closed by a hinged door, which latter is controlled by locking-lever. The invention further consists in the water-supply pipe being adapted to be raised, rotated, and lowered so as to effect the sluicing process.

No. 19683.—6th July, 1905.—THOMAS EDWARDS, of Ballarat, Victoria, Australia, Metallurgist. Improvements in tilting ore-roasting furnaces.

Extract from Specification.—I combine with the tilting-furnace multiple rows of rabbles, and this permits of short armed rabbles being used, a matter of importance, for the reasons aforesaid, and for others notable in tilting-furnace practice. The invention comprises other features novel in the “Edwards” tilting-furnace, having the effect of economizing much heat hitherto wasted, the result being greater output on less consumption of fuel. This furnace may now be of any width and capacity; it will be set to work horizontally or at an incline, being adjusted to accommodate all classes and grades of ores; and a rapid and a more perfect roast is promoted than formerly.

No. 19684.—6th July, 1905.—RICHARD HENRY COOKE, a member of the firm of Bedgood and Company, of Nos. 172–174, Flinders Lane, Melbourne, Victoria, Australia, Boot and Shoe Warehousemen. An improved boot-upper.

Claims.—(1.) An improved boot-upper having a comparatively long narrow tongue or strap cut in the back thereof and used as a reinforcing piece, substantially as described. (2.) An improved boot-upper having a comparatively long narrow tongue or strap cut in the back thereof, with slightly convex sides, and used as a reinforcing piece, substantially as described. (3.) An improved boot-upper having a comparatively long narrow tongue or strap cut in the back thereof, with sides converging towards their lower ends, and used as a reinforcing piece, substantially as described.
