(5.) A velocipede comprising a driving-wheel having ordinary bearings in frame, a steering-wheel set with its axle free to rotate and slide in bearing-slots in the frame, uprights supported by frame, foot-plates having sleeves with internal rollers encircling the uprights, spiral springs encircling uprights and sleeves and supporting foot-plate, rod articulated to foot-plate and connected to crank, spindle carrying crank and sprocket-wheel, sprocket-wheel on driving-wheel axle, endless chain between the two sprocket-wheels, and means connected with the velocipede for holding same securely in position against shoe of operator, substantially as set forth. (6.) A velocipede comprising two wheels, a frame forming bearings for said wheel, the axle of back or steering-wheel being provided with boxes with curved discs, said axle being set with the boxes free to slide in bearing-slots formed in the frame and with the discs forming limiting stops, upright rods mounted on the frame, foot-plate carrying sleeves encircling the upright rods, spiral springs encircling the rods and sleeves and supporting the foot-plate, and means of communicating motion from the foot-plate to the driving-wheel of velocipede, substantially as set forth. (7.) A velocipede comprising a driving-wheel having ordinary bearings in frame, a steering-wheel having an axle provided with boxes with curved discs, said axle being set with the boxes free to slide in bearing-slots formed in the frame and with the discs forming limitation stops, uprights supported by frame, foot-plates having sleeves with internal rollers encircling the uprights, spiral springs encircling uprights and sleeves and supporting foot-plate, said sleeves and springs being enclosed in flexible protecting material, rod articulated to foot-plate and connected to cushion crank, spindle carrying crank and sprocket-wheel, sprocket-wheel on driving-wheel axle, endless chain between the two sprocket-wheels, and adjustable toe- and heel-clips and leg-strap connected with the velocipede for holding same securely in position against shoe and leg of operator, substantially as set forth. (8.) The combination and arrangement of the several parts for the purposes described, and as illustrated on the drawings.

No. 13422.—21st February, 1901.—GOLDEN LINK CONSOLIDATED GOLD-MINES (LIMITED), of 20 and 21, Lawrence Lane, Cheapside, London, England (assignees of Henry Joshua Phillips, of 123, Palace Chambers, Westminster, England, Fellow of the Institute of Chemistry). Improvements in or relating to the extraction of precious metals from certain of their ores.

Claims.—(1.) The described method of extracting precious metals from refractory or rebellious ores of the character specified, which consists in subjecting the powdered ore to the action of a weak (say 0·5 to 3 per cent.) solution of alkaline polysulphides, the amount of polysulphide employed being insufficient to dissolve the gold itself, but proportioned as described so that it will dissolve the elements combined with the gold without dissolving the gold, whereby the latter is dissociated, and can then be recovered by the well-known cyaniding or other suitable process for recovering free gold. (2.) The described method of extracting precious metals from refractory or rebellious ores of the character specified, which consists in subjecting the powdered ore, under heat and pressure, to the action of a weak (say 0·5 to 3 per cent.) solution of alkaline polysulphides, the amount of polysulphides employed being insufficient to dissolve the gold itself, but proportioned as described, so that it will dissolve the elements combined with the gold without dissolving the gold, whereby the latter is dissociated, and can then be recovered by the well-known cyaniding or other suitable process for recovering free gold. (3.) The described method of extracting precious metals from refractory sulphide or telluride ores without roasting, which consists in subjecting the ore in the form of a powder, and without roasting, to the action of alkaline polysulphides in solution of such weakness and so proportioned that same will have a selective action — namely, will dissolve the elements which are combined with the gold and for which the polysulphides have a greater affinity than for gold, without dissolving the gold itself, which latter is thus dissociated, and can then be recovered by any known suitable process for recovering free gold, substantially as set forth. (4.) The described method of extracting precious metals from refractory sulphide or telluride ores without roasting, which consists in subjecting the ore without roasting and in the form of a powder, under heat and pressure, to the action of alkaline polysulphides in solution of such weakness and so proportioned that same will have a selective action — namely, will dissolve the elements which are combined with the gold and for which the polysulphides have a greater affinity than for gold, without dissolving the gold itself, which latter is thus dissociated, and can then be recovered by any known suitable process for recovering free gold, substantially as set forth.

No. 13435.—1st March, 1901.—JOHN ANSCHAU, of Glen Innes, New South Wales, Postmaster. An improved sealed buckle.

Claims.—(1.)

(2.) In a buckle-seal, the combination of a strip of cardboard or other similar material with a metal strip adapted to engage a corresponding catch on the frame of the buckle, substantially as described, and as illustrated in the drawings. (3.) A sealing-buckle internally slotted and provided with a suitable catch to receive and retain a cardboard seal provided with metal-spring attachment to engage the said catch, substantially as described, and as illustrated in the drawings. (4.) The combination of a sealing-buckle internally slotted and provided with a suitable catch, with a seal made of cardboard or other suitable material provided with a metal strip adapted to engage the aforesaid catch, substantially as described and as illustrated.
