No. 22669.—10th April, 1907.—ALWIN FISCHER, of O'Connell Street, North Adelaide, South Australia, Plumber. Improved atmospheric gas-burner.

Claims.—(1.) In atmospheric gas-burners, a hollow shaft for the passage of gas and air, attached to a gallery and having an enlarged top as illustrated. (2.) In atmospheric gas-burners having a hollow shaft fixed on a gallery and having an enlarged top, a cover or spreader, similar in shape to the enlarged top of the shaft, for the purpose of evenly distributing the gas and air. (3.) In atmospheric gas-burners having a shaft with an enlarged top, and having a spreader or cover, one or more rims with grooves to form outlet-passages for the gas and air, such grooved rims being either separate or attached to the enlarged top of the shaft and the under-side of the cover or spreader. (4.) An atmospheric gas-burner consisting of a gallery on which is fixed a shaft enlarged on the top,

and a cover or spreader similar in shape to the enlarged top of the shaft, together with a rim or rims having grooved passages for the escape of gas and air, all substantially as described and shown, forming a combination of parts.

No. 22673.—11th April, 1907.—RICHARD SYLVESTER, of 25 Victoria Avenue, Lindsay, Victoria, Ontario, Canada, Manufacturer of Agricultural Implements. Improvements in or relating to agricultural machines.

Extract from Specification.—This invention relates to certain new and useful improvements in agricultural machines having a traction-truck to which can be detachably connected the separator of a threshing-machine, or which can be employed to draw a gang of ploughs, drag a series of cultivators or seeding-machines, carry a harvester-binder, or perform any other power work ordinarily required in farming operations, the traction-truck being provided with a motive mechanism which can be employed to propel the traction-truck and actuate the operating parts of the machine propelled thereby. The invention further relates to the peculiar construction and arrangement of the main and fore carriages constituting the essential parts of the traction-truck, and to the peculiar manner in which the steering-wheels are connected to the fore-carriage to compensate for any variation in the level of the path over which the traction-truck is travelling, and to the controlling-mechanism for the steering-wheels whereby they will be quickly sensitive to any desired change of direction. The invention further relates to a grain-carrier for the separator, consisting of a grain table extending from the front end of the separator at a place below the concave and grates of the cylinder to the vicinity of the sieves, and located below the plane of the straw-decks but above the plane of the sieves, and a grain-belt travelling above the top surface of the grain-table, to drag or convey the grain and chaff from the cylinder to the sieves and thus maintain a regular and continuous delivery of the grain and chaff thereto, irrespective of the inclination of the apparatus from a horizontal plane. This invention further relates to the peculiar construction of the feeder, and its location on the top of the separator, whereby the entire weight of the separator will be evenly balanced on both sides of the axle of the traction-wheels, and to a sheaf-carrier and elevator positioned at the sides of the feeder to receive the sheaves and evenly and continuously deliver them to the feeder-carrier. The invention further relates to the water-cooling means for the motor, which consists of a fan carried by the traction-truck and forming an inseparable part of the motor employed to propel the traction-truck and actuate the driven parts of the apparatus, and a water-casing also carried by the traction-truck enclosing or partially enclosing the fan-casing, and suitably connected with the water-space of the water-jacket of the motor, whereby a circulation of water may be maintained from the water-jacket to the water-casing, from which the heat units or calories are extracted by the circulation of the air caused during the revolution of the fan.

No. 22676.—11th April, 1907.—THOMAS IGNATIUS YOURELLE, of Harcourt's Building, Lambton Quay, Wellington, New Zealand, Architect, and JOHN BELLINGHAM, of Featherston Street, Wellington aforesaid, Importer. Improvements in ferro-concrete and fireproof construction.

Claims.—(1.) The improvements in ferro-concrete and fireproof construction set forth, and illustrated in the drawings. (2.) For the purpose indicated, the employment of a framing composed of metal tubes, said tubes carrying clips for the purpose of supporting facing-material, substantially as set forth. (3.) For the purpose indicated, a framing composed of metal tubes, in combination with strips secured to said clips to form stanchions or studs, and facing-material secured to said strips, substantially as set forth. (4.) For the purpose indicated, a framing of metal tubes, in combination with clips upon said tubes, strips secured to the clips, and facing secured to the strips, substantially as set forth. (5.) For the purpose indicated, a framing of metal tubes, in combination with clips upon said tubes, strips secured to the clips, facing secured to the strips, and wires connecting the clips, substantially as set forth. (6.) For the purpose indicated, a framing of metal tubes, in combination with clips upon said tubes, strips secured to the clips, facing secured to the strips, and concrete or other material filling the spaces between the frame and the facing, substantially as set forth.
