(2.) The process of mechanically soldering vessels such as cans or receptacles, which consists in applying melted solder to one or both of the parts to be soldered together, placing the parts separately in a holder whereby they are held firmly in proper relation to each other, forcing said parts together by yielding pressure, and then subjecting one or both of said parts adjacent to the joint to the action of heat until the solder has been evenly distributed along the joint, and continuing the pressure until the solder has set or hardened, substantially as described. (3.) An apparatus for the soldering of vessels such as cans or receptacles, comprising a holder having a rigid bottom and rigid sides to receive separately the parts to be soldered together after one or both of said parts have been dipped in solder, and to hold same firmly in proper relation to each other, said holder being provided with means for yieldingly forcing said parts together until the solder has been distributed along the joint, substantially as described. (4.) An apparatus for the soldering of vessels such as cans or receptacles, comprising a holder for the parts to be soldered together, a cover for said holder movably mounted upon a bar pivoted to the holder, a spring interposed between the bar and cover whereby the cover is yieldingly forced into engagement with one of the parts contained in the holder, and the solder evenly distributed along the joint, substantially as described. (5.) An apparatus for the soldering of vessels such as cans or receptacles, comprising a holder for the parts to be soldered together, a cover for the holder, means for yieldingly pressing said cover in engagement with one of said parts, said holder being provided with openings in its bottom adjacent to the joint between the parts to be soldered, substantially as described. (6.) An apparatus for the soldering of vessels such as cans or receptacles, comprising an endless carrier, a holder secured to said carrier, said holder corresponding in shape with a wall or body of the vessel and adapted to receive separately the parts to be soldered together and to hold said parts in contact with each other, and means for heating or cooling the parts to be soldered when the carrier is moved, substantially as described.

No. 14218.—13th November, 1901.—CHARLES ANKETELL, of Greytown North, New Zealand, Farmer. Improved bag-gripping apparatus for use in filling bags with chaff or other matters.

Claims.—(1.) The improved bag-gripping apparatus consisting of the parts arranged, combined, and operating substantially as specified and illustrated. (2.) In apparatus for the purpose indicated, a gripping-band partially surrounding a filling-cylinder over which the mouth of a bag is passed, and means whereby, when a lever is operated, said band is caused to clamp the bag upon said cylinder, substantially as described and illustrated. (3.) Apparatus for the purpose indicated, consisting of a gripping-band partially surrounding a cylinder over which the mouth of a bag is passed, the ends of said band being supported by lever-arms which are arranged to be operated by a pivoted bifurcated lever whereby the gripping-band is brought down and clamped upon the mouth of the bag, substantially as specified and illustrated. (4.) In apparatus for the purpose indicated, the combination of a screw compressor-cylinder, a bell-mouthed ring upon it, a gripping-band partially surrounding said ring, lever-arms carrying the ends of said levers and journaled in a bracket fixed upon the ring, a bifurcated lever pivoted upon a pin carried in said bracket and receiving said lever between its arms,

and a lever fixed at one end in the rocking-shaft, and having one end of a tension-spring secured upon it, the other end of said spring being secured to said bracket. (5.) In apparatus for the purpose indicated, the combination of a screw compressor-cylinder, a bell-mouthed ring upon it, a gripping-band partially surrounding said ring, lever-arms carrying the ends of said band, journaled in sleeves upon a hinged plate pivoted upon a bracket carried upon said ring, a stud-pin passing through a slot in the hinged plate and screwed into the bracket, a spring upon said stud bearing against an adjusting nut thereon at one end and against the bracket at the other, and a pivoted bifurcated lever designed to operate upon said lever-arms and cause the band to grip a bag upon the ring. (6.) In apparatus for the purpose indicated, the construction and mode of applying the pivoted bifurcated lever for operating the lever-arms carrying the gripping-band whereby said lever-arms are drawn together and the gripping-band closed. (7.) The combination in apparatus for the purpose indicated of a gripping-band carried by lever-arms pivotally supported at their upper ends in such manner that, when suitable means for operating them is actuated, a backward, upward, and outward movement is imparted to said gripping-band, substantially as specified and illustrated.

No. 14220.—14th November, 1901.—EVAN HENRY HOPKINS, of 32, Redcliffe Square, South Kensington, Middlesex, England, Clerk in Holy Orders. Improved process for obtaining zinc.

Claims.—(1.) The process of obtaining zinc free from lead, from mixtures of the oxides of zinc and lead, such as are obtained by roasting lead-zinc sulphide ores, by heating the oxides mixed with carbonaceous material in a closed retort, and passing the products of distillation through carbon heated to incandescence. (2.) The process for obtaining zinc substantially as described.
