so that such lever will spring in and press the first lever out of contact with the mechanism, and means whereby such levers may be returned to their normal positions again, as specified. (4.) In apparatus for starting and timing races, spring-actuated mechanism adapted to operate a bell-hammer, a cam-disc secured to and adapted to revolve with such mechanism, a pair of spring levers of different tension springing towards each other and provided with anti-friction rollers adapted to revolve on the periphery of the cam-disc, such cam-disc being formed with a depression in its periphery that lies normally opposite the roller upon the stronger lever, and one edge of which is inclined to the periphery, so that, when such lever is released to spring in and push the other lever, by means of a cross-bar, away from contact with the mechanism so that the same will operate, the revolving cam-disc will press it back again into its normal position, to be retained by a catch on the armature of an electro-magnet, as set forth. (5.) In apparatus for starting and timing races, spring-actuated mechanism, one wheel of which is formed with projections on its face, a hammer-spindle mounted within the mechanism and provided with radial extensions adapted to be engaged and released by the projections on the wheel, as the same is rotated, so as to cause the hammer to strike a bell, as specified. (6.) In apparatus for starting and timing races, spring-actuated mechanism adapted to operate a bell-hammer, a drum mounted upon and adapted to be rotated with such mechanism and a drum mounted upon a spring-controlled spindle, such drums being connected and adapted to revolve together by means of an endless cord encircling them, an indicator pointed upon the end of the drum-spindle, and a dial across the face of which such indicator-pointer revolves, as set forth. (7.) In apparatus for starting and timing races, a clockwork mechanism provided with an insulated metallic dial formed with peg-holes therein, and with a seconds hand electrically connected with the clockwork provided with a spring engaging with metallic pegs placed in the holes on the dial, spring-actuated mechanism adapted to operate a bell-hammer, and provided with means for keeping such mechanism from actuating an electric battery, one pole of which is connected to the clock-dial, while the other is connected through an electro-magnet and make-and-break switch to the clockwork and seconds hand, so that as such seconds hand revolves and brushes against each peg in the dial a circuit will be completed and the electro-magnet energised to release the striking-mechanism and cause a bell to sound, as specified. (8.) The general arrangement, construction, and combination of parts in my improvements in apparatus for starting and timing races, as described and explained, as illustrated in the sheet of drawings, and for the several purposes set forth.

No. 14198.—6th November, 1901.—RICHARD KEYTE, of Whangarei, Auckland, New Zealand, Builder. Improved means for automatically indicating a change in temperature.*

Claims.—(1.) In means for indicating a change in temperature, a bell provided with a spring-actuated tongue, a collar upon a sliding spindle engaging with and holding the tongue from movement, and a capsule upon the end of the spindle composed of flexible walls and containing a fluid of a nature such that it will expand and contract when subjected to heat and cold, as specified, (2.) In means for indicating a change in temperature, a bell provided with a spring-actuated tongue and mounted upon a suitable base secured to a frame by means of which it may be fixed in any desired position, a collar upon a spring sliding spindle engaging with and holding the tongue, a capsule composed of flexible walls and containing a fluid susceptible to expansion and contraction by heat and cold, which is secured to the end of the sliding spindle, and a regulating screw within the frame, the end of which bears against the other side of the capsule, as set forth.

No. 14228.—14th November, 1901.—FRANK TOWNSEND MUMFORD, of Kalgoorlie, Western Australia, Metallurgist. Improvements in the electrolytical treatment of ores and slimes for the recovery of precious metals therefrom, and apparatus therefor.*

Claims.—(1.) In an electrolytical process of extracting precious metals from ores or slimes, the employment of a bath of mercury which continuously lies on the lowermost part of the amalgamated copper lining of a revolving cylinder, whereby such lining makes contact by submersion with same for the continuous replenishment or washing of such lining with a renewed film of mercury, so as to maintain the surface of such lining in a ceaseless state of efficiency and cleanness, substantially as and for the purposes described and explained. (2.) An electrolytical process of extracting precious metals from ores or slimes which consists in the ore being agitated within a cylinder revolving on its horizontal axis, said cylinder being provided with longitudinal bars as anodes, and with an amalgamated internal lining constituting the cathode, and on which the precious metals are deposited in an adherent form, said lining having a self-contained body of mercury lying on its lowermost part, the apparatus being in communication with electric energy, substantially as described and explained, and as illustrated in the drawings. (3.) In an electrolytical process for gold-recovery, a cylinder revolving on a horizontal axis, having longitudinal bars, which constitute the anodes, and with an amalgamated copper lining in combination with a bath of mercury lying at the bottom on such lining, which mercury forms the cathode for the deposition of the precious metals, substantially as described and explained, and as illustrated in the drawings. (4.) In an electrolytical process for gold-recovery, a cylinder revolving on a horizontal axis, and whose internal lining is continuously brought into contact by submersion with its own self-contained bath of mercury, so that such lining is maintained in a continuous state of efficiency for purpose of amalgamation, substantially as and for the purposes described and explained, and as illustrated in the drawings.

No. 14623.—14th March, 1902.—CHARLES WHITTINGHAM WYCHERLEY, of 74, Willis Street, Wellington, New Zealand, Saddler and Harness-maker. An improvement for securing horse-covers in position.*

Claim.—In means for securing horse-covers in position, a strap secured upon the inside of the cover on one side, and a similar strap secured upon the inside on the other side of the cover, in combination with loops attached to the back end of the cover through which the straps on the respective sides are passed, after passing round the horse’s legs, and are then secured together, as specified.

Claims.—(1.) In combination with a metal pan, a removable main lid fitting upon the top of the pan and provided with means for forming a close joint therewith, a seat-aperture formed in the main lid, and a secondary lid adapted to fit over such aperture and provided with means for forming a close joint with the edges thereof, as and for the purposes specified. (2.) In combination with a cover fitting over the top of a metal pan and provided with a seat-aperture therein, of a lid adapted to close and seal such aperture, and connected to the cover by means of a ring secured to the lid and passing over a horizontal bar secured to the cover, as and for the purposes set forth. (3.) The general arrangement, construction, and combination of parts in my improvements in or relating to closet-seats, as described and explained, as illustrated in the drawings, and for the several purposes set forth.
