No. 25086.—16th October, 1908.—FREDERICK CAPEL BROWN, of Waihi, Auckland, New Zealand, Mining Engineer. Improvements in apparatus for heating metal tools, such as mining-drills, boring-bits, and the like.

Claims.—(1.) The method of heating metal tools, such as mining-drills and the like, by introducing the ends to be heated into a narrow channel raised to a suitable temperature by the combustion of the liquid or gaseous fuel projected longitudinally along said channel in the manner specified, as described and illustrated. (2.) The apparatus consisting of the furnace arranged with a narrow channel longitudinally through it, a burner adapted to project liquid or gaseous fuel mixed with air along said channel, and openings into said channel for introducing the ends of the tools to be heated, for the purpose set forth, as described and illustrated. (3.) The apparatus consisting of a furnace as specified, a burner adapted to project liquid or gaseous fuel mixed with air longitudinally through said furnace, and a device for heating the air that is used in said burner in the manner specified, as for the purpose set forth, as described and illustrated. (4.) The apparatus consisting of a furnace as specified, with openings for introducing the tools to be heated, and means for closing the openings when required, a burner adapted to project liquid or gaseous fuel mixed with air longitudinally through said furnace, with or without means for heating the air supplied to said burner, in the manner and for the purpose set forth as described and illustrated.

No. 25092.—16th October, 1908.—WILLIAM MURRAY, of Mokoreta, Wyndham, New Zealand, Inventor. An improved quick-acting shifting-spanner.

Claims.—(1.) In shifting-spanners, the combination of the usual fixed head and the usual movable one worked with a worm, but with means to put the said worm out of gear with the rack, and so quickly slide the movable head to approximately its desired position, all substantially as shown on the drawing, and as described and explained. (2.) In shifting-spanners, in combination, a fixed head and a head composed of a saddle-like piece free to move on the handle of the spanner, with a sliding inner saddle-like piece carrying the worm, but provided with a spring and means of pressing the said worm out of gear with the teeth of the usual rack, for rapid movements of the movable head, when the worm will automatically and normally engage the said teeth, and can be used for the finer adjustments, all substantially as set forth. (3.) In the movable head of a shifting-spanner, a worm so fixed to slide on a frame within the head that it normally engages its rack, and can be pushed closer to the fixed head, but if desired to be placed farther from it, pressure on the parts of the movable head disengages the worm from gear, allowing the head to slide freely in either direction, and release of the pressure allows a spring to re-engage the worm in gear, all substantially as set forth.
