No. 24793.—13th August, 1908.—JOHN POMEROY, of Invercargill, New Zealand, Inventor. Improvements in steam-boiler furnaces.*

Extract from Specification.—These objects are accomplished by forming at the back of the furnace an air-chamber which communicates with the ash-pit, and is formed by a series of curved spaced bars which constitute a hollow fire-bridge located between the inner ends of the ordinary fire-bars and the furnace-bridge. Heated air and steam are introduced into said chamber, and delivered through the hollow bridge into the flames of the furnace for the purpose of effecting complete combustion, and keeping the interstices of the fire-bridge clear. The bars of the hollow bridge are independently secured in position so that when any particular one is burnt or worn it is unnecessary to do more than replace such damaged one.

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

(Specification, 5s. ; drawing, 1s.)

No. 24859.—31st August, 1908.—JAMES MOTTERSHEAD COLLINS, Accountant, and JOHN LOW, Wheelwright, both of Palmerston North, New Zealand. Improvements in appliances for use in treating flax and like fibres.*

Claim.—Means for the purpose described, consisting of the combination with a travelling chain, band, or the like of a pair of bars arranged parallel to each other below such chain, and so adjusted that the edges of the chain will engage with and rest upon the adjacent edges of the bars, substantially as specified.

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

No. 24861.—28th August, 1908.—FREDERICK CAPEL BROWN, of Waihi, New Zealand, Engineer. Improvements in ore-treatment.*

Claims.—(1.) In ore-treatment, the method of returning the concentrates from the concentrating-machines to the grinding-machines again and again until reduced to the required degree of fineness. (2.) In ore-treatment, the arrangement by which the concentrates are returned to the grinding-machines from the concentrators until they are reduced fine enough to pass away from the concentrating-machines along with the lighter portions of the ore.

No. 24961.—23rd September, 1908.—ALFRED FERRIS, of 2 Annand Street, North Fitzroy, near Melbourne, Victoria, Australia, Teacher ; and JOSEPH JAMES POYNTON, of 114 Hambleton Street, Middle Park, Victoria aforesaid, Clerk. An improved post-hole digger.*

Claims.—(1.) In an implement of the class described, a helically curved blade making one complete turn around a central shaft, provided at its lower end with a leading point, and at its upper end with a tang or handle, a vertical cutting-member formed circumferentially on either end of the said blade, substantially as described and illustrated, and for the purposes set forth.

No. 25020.—6th October, 1908.—HAROLD SHEEN MARTIN, of 16 Cumberland Street, Liverpool, Lancaster, England, Electrical Engineer. A composition applicable for use for the purpose of damping, transmitting, or reproducing mechanical vibrations, and, if desired, translating them into electrical variations.*

Claims.—(1.) A composition applicable for use for the purpose of damping, transmitting, or reproducing mechanical vibrations or impulses, which consists of a mixture of granular material with a material in the form of small springy scales or flakes, the damping action being obtained by the resistance to distortion offered by the scales or flakes, substantially as described.

No. 25030.—7th October, 1908.—JAMES HENRY GRANT, of Wodonga, Victoria, Australia, Metallurgist. An improved method and apparatus for destroying rabbits and other like animals.

Extract from Specification.—I accomplish this object by applying to the burrows, warrens, or other like places a gas or fumes consisting of hydrocyanic acid or prussic acid in conjunction with a carrying-gas to mix with the said prussic acid and assist in its conveyance into the burrows or warrens. The hydrocyanic acid is generated by the action of the acid (say, nitric acid) upon the cyanide of [an alkaline earth (say, potassium acid). This carrying-gas preferably consists of sulphuretted hydrogen with or without sulphurous acid. As an apparatus I provide a portable generator for the formation of hydrocyanic acid and sulphuretted hydrogen, with or without a furnace for the formation of sulphurous acid, in combination with a blower or fan for forcing the fumes into the burrows, warrens, or other like places.

No. 25103.—21st October, 1908.—UNITED SHOE MACHINERY COMPANY, of Paterson, in the State of New Jersey, United States of America, a corporation duly organized under the laws of said State of New Jersey, carrying on business as Shoemachinery Manufacturers, and having a place of business at 205 Lincoln Street, Boston, Massachusetts, United States of America (assignees of Orrell Ashton, of Lawrence, Essex, Massachusetts aforesaid, Machinist). Improvements in or relating to machines for use in conforming uppers to lasts.*

Claims.—(1.) For a machine for conforming uppers to lasts, a rotary pounding-device having beating-members retained thereon by supports between which and the members there is slack whereby the said members will be held outward by centrifugal force, but will swing and move inward on contact with the work, with or without smoothing-means reciprocated lengthwise of the edge of the shoe. (2.) A constructional form of the pounding-device claimed in preceding claiming-clause No. 1, in which the beating-members are constituted by rings or rolls having openings of larger dimensions than their supports.

[NOTE.—Here follow five other claims.]
