An improvement in wrapping-machines.

Claims.—(1.) In a machine of the character set forth, the combination with a wrapper-folding chute and a reciprocatory package-pusher therein, of a wrapper-support above said chute with means enabling the package to be lowered into the chute, and a reciprocating gate adapted to serve as a guide in the lowering operation. . . . (10.) The improved wrapper-feeding mechanism comprising a wrapper-pile holder having a cut-away bottom, a transversely disposed shaft equipped with spaced suction nipples adapted to bend the rear portion of the lower sheet downwardly, and a separator and wrapper-pile elevator comprising a plunger and a rock-member mounted thereon and equipped with a separator-plate, whereby the separation and elevation of the wrapper-pile from the lower wrapper is effected by a compound movement.
(Specification, 18s. 6d.)

[NOTE.—Here follows one other claim.]

No. 30799.—30th January, 1912.—ROBERT THOMSON, of 164 Nithsdale Road, Pollokshields, Glasgow, Scotland, Architect. Improvements in piles, piers, wharves, and like structures.

Claims.—(1.) A pile or pier having a lateral inverted bowl-like projection above its entering-end, and with or without a cutting-edge, as set forth.
(Specification, 3s. 6d.)

[NOTE.—Here follow four other claims.]

No. 30800.—30th January, 1912.—ROBERT THOMSON, of 164 Nithsdale Road, Pollokshields, Glasgow, Scotland, Architect. Improvements in column and floor or beam connections.

Extract from Specification.—According to the invention, there is provided a single rigid interconnecting metallic diaphragm member of a hub-like form, which is seated directly upon and carried primarily by the vertically disposed members of the columnar structure, and is adapted to receive and support the laterally disposed metallic members which carry the floors, roofs, or other substantially horizontal structures, and to transmit the load-stresses thereof to the columnar member to which it is affixed and on which it is carried.
(Specification, 7s. 6d.)

No. 30801.—30th January, 1912.—ALFRED SMALLWOOD, of 42 Hargrave Park, Highgate, London N., Middlesex, England, Metallurgist. A new or improved rotary furnace or firebox.

Extract from Specification.—According to this invention, I provide a firebox comprised essentially of a substantially imperforate rotating metal cylinder, combined with a longitudinally grooved refractory lining, a stationary injector or injectors is or are adapted to inject air, steam, fuel, or the like in a direction longitudinally of the firebox into the groovings, and at their extremities nearest the injector the groovings are enlarged or gradually widened so that the stationary injector injects successively into the various grooves or channels in a particularly satisfactory and efficient manner.

Hollows provided in addition to the groovings may be formed in the bricks, and in said hollows radiators may be provided to extract and radiate heat from the lining. Other metal parts may be provided in the form of plates disposed one on each side of each of the groovings or channels.
(Specification, 14s.)

[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 30802.—30th January, 1912.—HUEBNER-BLEISTEIN PATENTS COMPANY, a corporation organized under the laws of the State of New York, and carrying on business as a manufacturing and selling company, at No. 180 Kensington Avenue, in the City of Buffalo, New York, United States of America (assignees of William Carl Huebner, of No. 180 Kensington Avenue aforesaid, Manufacturer). Improvements in adjustment-controllers.

Extract from Specification.—The adjustment-controller comprises two sets of wheels or members, one set which is stationary during the adjusting movement, but adjustable, and is set to correspond with the desired adjustment of the adjustable part, and another set of which the wheels or members are driven in unison with the adjustable part so that the adjusting movement of such part is reproduced or represented by the movement of these driven wheels or members. Each set comprises a unit wheel or member and a fraction wheel or member. The divisions, whether inches or centimeters, are marked on appropriate scales. The driven wheels or members are so connected with the adjusting-mechanism that the unit wheel or member is driven a distance equal to one of the unit-divisions of the unit-scale for each unit of travel of the adjustable part, and the fraction member or wheel is driven the full length of a fraction-scale which represents one unit of the unit-scale. When the adjustable wheels or members of the controller have been set for a desired adjustment and the adjusting-mechanism has been started by closing the switch, the movement of the adjusting-mechanism will continue until the driven members of the controller reach positions which coincide with the positions of the stationary adjustable members. When the two sets of wheels or members so coincide, electrical contacts are automatically connected, and the clutch is thrown out of action, thereby stopping the movement of the adjusting-mechanism.

No. 30804.—31st January, 1912.—HUGH MACKENZIE LESLIE, of 53 Waterloo Street, Glasgow, Scotland, Metallurgical Engineer. Improvements in the treatment of ores by the cyanide process.

Claims.—(1.) The improvement in the cyanide process for treating ores consisting in collecting or drawing off the cyanogen containing gases liberated during the treatment and bringing these gases again into contact with ore so as to act thereon. (2.) In the treatment of ores by the cyanide process, covering the vessels or places where the cyanogen compounds in gas or solution are found, contained, or are used, in or for the process of extraction, and carrying off the gases from these covered vessels or places, and thereafter returning these gases directly or indirectly back again to the agitators (or other vessels in which the ore is being treated) so as to again come in contact with the ore and act thereon.
(Specification, 10s. 6d.)

[NOTE.—Here follow two other claims.]

No. 30805.—31st January, 1912.—HUGH MACKENZIE LESLIE, of 53 Waterloo Street, Glasgow, Scotland, Metallurgical Engineer. Improvements in the extraction of metals from their ores.

Claims.—(1.) In the treatment of ores by the cyanide process, covering the vessels or places where the cyanogen compounds in gas or solution are found, contained, or are used, in or for the process of extraction, and carrying off the gases from these covered vessels or places and conducting them to one or more regenerating-vessels, where they are subjected to the action of an alkaline hydrate or carbonate so as to fix the hydrocyanic acid in the gases, the solution from the regenerating vessel or vessels being drawn off as required and added to the sump so as to strengthen the solution therein, the solution from the sump being pumped or conducted, either directly or indirectly, to the vessel or vessels in which the ore is undergoing treatment, the arrangement constituting a circulatory system whereby the hydrocyanic-acid gas, which is continuously evolving during the treatment, is continuously being regenerated into a simple cyanide-solution and continuously being reused again in the treatment, substantially as described. (2.) A plant for carrying out the cyanide process for treating ores comprising, in combination, a combined pulp-collector, agitator, and dewatering-device, a filter, an extractor, and a regenerator, the same being connected with the sump and either directly or
