[No. 102

Extract from Specification.—The purpose of this invention is to work and treat tow, whereby it will be cleaned of dust and short fibres, and the good fibres be prepared for use. This result is accomplished by teeth or spikes being set into the periphery of a drum or cylinder at an angle, which teeth catch or take up the tow as it is fed on to them, and the drum or cylinder being made to revolve in the direction of the trend of the teeth or spikes, whereby the short fibre and dust are thrown off from the drum or cylinder, and the good and longer fibre is gathered in close on the periphery of the drum and cylinder, from which it is taken off in swaths.

No. 18731.—10th November, 1904.—HARRY SHOEMAKER, of 51, Astor Place, Jersey City, Hudson, New Jersey, United States of America, Electrical Engineer. Wireless-telegraph system.

Extract from Specification.—My improvements relate to transmitting and receiving apparatus for use in sending messages through space by the agency of electro-radiant energy, and without the employment of conductors extending between the transmitting and receiving stations. My transmitting apparatus comprises a freely oscillating circuit having a condenser, spark-gap, and an inductance winding connected in series with each other, the radiating conductor being connected in shunt with the condenser of the freely oscillating circuit. My improvements in receiving apparatus reside in the wave-responsive device or detector, by means of which the arrival of electric radiations may be recorded or manifested.

No. 18740.—8th November, 1904.—WILLIAM WALKER BRUCE, of 8, Park Street, Thorndon, Wellington, New Zealand, Commercial Traveller (nominee of John Russell Little, of 20, Royal Crescent, Edinburgh, Scotland, Iron and Steel Girder). Improvements in and relating to fireproof floors, roofs, and like structures.

Extract from Specification.—This invention has reference to improvements in and relating to fireproof floors, roofs, and like structures, and refers more especially to the floors design, and material of the composition tubes or perforated blocks used, which will be easily placed in position, and will also serve as conduits or reservoirs for water to supply fire-extinguishing sprinklers or the like. Said tubes or blocks are fixed in position by a self-locking device attached to and forming part of the tubes or blocks, whereby it is impossible for them to fall out or get displaced when inserted between steel joists.

No. 18754.—16th November, 1904.—LUCY ADAMSON, of Waimate, Canterbury, New Zealand, Domestic Duties. An improvement in apparatus for the collection of rain-water.

Claim.—In apparatus for the purpose indicated, in combination, a closed receptacle, the end of a downpipe fitting therein, a float within the receptacle, vertical guide-rods therefor, a ball carried upon said float adapted to close the lower end of the downpipe when water rises to near the top of the receptacle, substantially as specified and illustrated.

No. 18769.—17th November, 1904.—JOHN THOMAS DAWES, of The Lilacs, Prestatyn, Flint, England, Mining Engineer. Improvements in magnetic separators for ores or the like.

Extract from Specification.—The invention relates to machines having a moving surface upon which the material is fed, and another moving surface above the first surface, to which second moving surface the magnetizable particles are attracted by a magnet arranged above the second surface. The objects of my invention are to provide means whereby the particles attracted to the second moving surface may be more certainly led away from the first moving surface and prevented from being carried along therewith by friction; and whereby the distance of the magnet and second moving surface from the first moving surface may be readily adjusted.

No. 18775.—21st November, 1904.—GEORGE ARMSTRONG, of Roslyn, Dunedin, New Zealand, Engineer and Draughtsman. Improved elevating apparatus for delivering material from one place to another.

Extract from Specification.—This invention provides apparatus for throwing coal, gravel, clay, and the like from one place to another, and is particularly applicable to gold-dredges for stacking tailings, including silt from the tables. According hereto, material to be conveyed is intermittently delivered to a bucket which is fixed to a slide-block working upon inclined guides. Rapid motion is imparted to the bucket with the material within it in the manner hereinafter to be described, and when the bucket’s velocity is decreased the material leaves it on account of the momentum which has been imparted to it, and is thrown to a distance depending upon the velocity of the bucket and the specific gravity of the material. Intermittent motion is imparted to the bucket from a constantly revolving shaft in the following manner: The slide-block referred to is connected by a rod with the end of a rocking-beam, which is pivoted at its other end in a fixed support. A disc upon the revolving shaft referred to carries a crank-pin, upon which is pivotally connected one end of a lever, the opposite end of which is knuckle-jointed to the outer end of another lever pivoted upon the rocking-beam referred to. The parts are so arranged that the knuckle-jointed levers only straighten out when required, the knuckle-joint being upon the outside of a line drawn between the crank-pin and the point of connection on the rocking-beam. The revolution of the crank-shaft, therefore, has no effect upon the rocking-beam. When, however, the rocking-beam is caused to rise upwardly upon its pivot for a short distance, room is given for the knuckle-jointed levers to straighten out, whereby rapid movement is transferred to the rocking-beam and the bucket operated.

No. 18783.—24th November, 1904.—WILLIAM JAMES JOHNSTON, of Rock Springs, Sweetwater, Wyoming, United States of America, Photographer. Panoramic camera.

Extract from Specification.—In operation the film is placed on the roll 3, one end thereof is then carried past the exposure-slot and secured to the feed-roll 11, which must be placed in relation to the exposing-slot so that the film will be drawn in the same direction as the lens travels in covering the view desired to be taken. The feed-roll draws the film past the exposing-slot at a uniform rate of speed, and proportionate to the focal distance of the lens. It also provides a means of disposing of the film after exposure. By releasing the lock and starting the fan the entire mechanism is placed in motion. The principle upon which panoramic cameras are constructed in order to accomplish the desired results is deduced from the fact that, as the diameter of the pinion 19, or spool, is to the diameter of the stationary rack, or disc, so is the diameter of the feed-roll to twice the focal distance of lens desired to be used.

No. 18795.—28th November, 1904.—GEORGE FINN, of 11, McFarlane Street, Wellington, New Zealand, Company-manager, and ARTHUR SELDON PIKE, of 168, Tinakori Road, Wellington aforesaid, Engineer. Improvements relating to egg-carriers.

Claims.—(1.) For the purpose indicated, a carrier of flat spring metal constructed to form a clip for the egg and a spring support for said clip, substantially as specified and illustrated. (2.) For the purpose indicated, a single piece of wire bent to form three independent loops, each loop curved to fit a portion of the periphery of an egg, the wire being continued downwardly from two of said loops to form legs, and battens spaced apart to which said legs are secured, one leg to each batten, substantially as set forth. (3.) For the purpose indicated, in combination, a clip to receive an egg, a spring support for said clip, and a tray the bottom of which is constructed of
