[No. 68

Extract from Specification.—A liner is made with an outside casing from which it is separated by flanges, thus leaving an annular space for the introduction of water, which is frozen in a freezing-chamber prior to the introduction of the milk into the liner. The milk is agitated by means of a hollow pendulum suspended by a hook from the top of the can. This pendulum is hollow, and provided with a screw cap for the introduction of water which is frozen in a freezing-chamber, and introduced into the can after the milk has been placed therein.

No. 21150.—16th May, 1906.—ROBERT WILLIAM JEFFREY, of Eaglehawk, Victoria, Australia, Merchant (assignee of Joseph Henry Pickles, of Victoria Street, Eaglehawk aforesaid, Miner). An improved safety bucket-hauling device for use in shaft-sinking and similar work.

Claims.—(1.) A safety bucket-hauling device for use in shaft-sinking and similar work, comprising a framework fitted with safety dogs or grippers in combination with means for automatically releasing the haulage rope and bucket therefrom when the bucket reaches the lower end of the timbered portion of the shaft, substantially as and for the purposes specified. (2.) In a safety bucket-hauling device for use in shaft-sinking and similar work, a framework fitted with safety dogs or grippers in combination with a catch (14) normally engaging a shoe on the haulage rope, and adapted to be released when the cage reaches a certain depth in the shaft, substantially as and for the purposes specified. (3.) In a safety bucket-hauling device for use in shaft-sinking and similar work, a shoe upon the haulage rope in combination with a sliding catch (as 14) together with a connecting-rod and bell crank lever actuated by a stop near the lower end of the shaft, substantially as and for the purposes specified. (4.) The combination and arrangement of parts constituting the improved safety bucket-hauling device, said parts being constructed, arranged, and operating substantially as and for the purposes specified, and as illustrated in the drawings.

(Specification, 3s. 6d. ; drawing, 1s.)

No. 21165.—17th May, 1906.—INTERNATIONAL HARVESTER COMPANY OF AMERICA, a corporation registered under the Companies Act of New Zealand, and having a place of business at Christchurch, New Zealand (assignees of John David Bywater, of Christchurch aforesaid, Attorney and Manager for the said company). An improved finger-attachment for mowing and reaping machines.

Claim.—(1.) An attachment for the fingers of mowers or reapers, the same consisting of a plate pointed at its forward end, and formed with a rearwardly extending member upon its upper edge, and with a rearwardly extending member upon its lower edge, such lower member being curved upwardly and downwardly so as to form a recess in its bottom edge, and being formed with a boss at its rear end adapted to rest and be bolted upon the finger-bar of the machine, a bore in the forward end of such recess adapted to receive the point of a finger, and a set-screw passing upwards through the lower member, and the head of which is adapted to rest and bear upon the top of the finger when the attachment is placed thereon, substantially as specified.

No. 21167.—17th May, 1906.—NEHEMIAH GUTHRIDGE, of 486 Collins Street, Melbourne, Victoria, Australia, Merchant (assignee of William Legrand Card and Frank Smith Card, both of Denver, Colorado, United States of America, Mechanical Engineers). Multiplane deck for ore-concentrator.

Extract from Specification.—I preferably construct the table or deck of a plurality of planes or surfaces of constant area, said planes being inclined with respect to each other, and one or more of said surfaces being inclined downwardly from the rear end towards the front end and having a decreased transverse inclination, whereby the side flow of the pulp is sufficiently retarded to induce proper stratification, and at the same time a longitudinally forward travel of the values is established, and such a construction embodies a further feature of my invention. In order to adapt the gradient of such of said planes or surfaces of the deck or table as are inclined forwardly downward towards the front end of the table to the varying character of the pulp or other material to be operated upon and to the varying volume of dressing-water required therefor, I preferably render said planes adjustable, or, in other words, I preferably construct the multiplane deck with its planes relatively adjustable, and such a construction embodies a further feature of my invention.

No. 21168.—17th May, 1906.—NEHEMIAH GUTHRIDGE, of 486 Collins Street, Melbourne, Victoria, Australia, Merchant (assignee of William Legrand Card and Frank Smith Card, both of Denver, Colorado, United States of America, Mechanical Engineers). Self-lubricating dust-proof head-motion for ore-concentrator.

Extract from Specification.—One feature of my invention, generally stated, resides in a mechanism for actuating concentrator-tables, wherein the co-acting elements are comprised of vibrating members having rolling contact, the point of contact receding from one centre of motion and simultaneously approaching the other centre of motion, so that a gradual acceleration and gradual retardation of the concentrator-table is alternately effected, and the power applied with greatest advantage. A further feature of my invention resides in the provision of an oil-well and protective cover for the operative mechanism, and means for automatically lubricating the pivots and bearings thereof, whereby labour and oil are saved and the life of the mechanism prolonged.

No. 21169.—17th May, 1906.—NEHEMIAH GUTHRIDGE, of 486 Collins Street, Melbourne, Victoria, Australia, Merchant (assignee of William Legrand Card and Frank Smith Card, both of Denver, Colorado, United States of America, Mechanical Engineers). Improved concentrator-feeder.

Extract from Specification.—In carrying out my invention, I construct a pulp-feeder for concentrators with a series of transverse riffles extending from the rear towards the front of the feeder for substantially two-thirds or three-fourths the length thereof, more or less, whereby the coarser particles of the pulp are arrested and directed towards the discharge-orifices at a distance from the rear of the feeder proportionate to the size of the particles, while the finer particles and slimes are carried to the front or plane portion of the feeder and discharged upon the table well forward and near the feed side thereof, and such a construction embodies one feature of my invention. In order that the fine metallic particles and slimes shall be discharged from the front end of the feeder upon the upper forward portion of the table, and to prevent their escape from the feeder at or near its rear end, I form the feeder-bottom with a transverse inclination downward towards the discharge side of the feeder, and adjacent to said side render the inclination abrupt so as to form a narrow channel contiguous to the discharge-orifices of the feeder, adapted to induce an accumulation of the coarser pulp and enable the fine metallics and slimes to be driven back from the discharge-orifices by a suitable flow of water introduced into the feed-box adjacent to the discharge-orifices thereof, and such a construction embodies a second feature of my invention. In order to arrest and guide the pulp-particles towards the discharge side of the feed-box at gradually increasing distances from the rear end of the box proportional to the relative size and specific gravity of the particles, I preferably arrange the riffles at an acute angle to the discharge side of the feed-box and reduce the height of the riffles gradually from the rear to the front of the box, whereby the advance of the fine metallics and slimes toward the front end and plane portion of the box is facilitated, and such a construction embodies a third feature of my invention.
