Title: A new or improved tool for tying articles or bundles with metal wire
IPC: B65B13/28
Filed: 1921-07-25
Abstract: 187,717. Kelsey, L. A. July 25, 1921. Twisting wires together; breaking; shearing- adjuncts.-A tool for twisting wires together for binding bundles of'cloth or wood, boxes, metal bars, girders, pipes, carpets, linoleum &c., consists of a hollow handle through which the wire is fed and a head to which the wire is secured and which is rotated by a reciprocating nut engaging a screw thread on the handle and so arranged either that the stress caused by the accumulating coils of wire severs the wire adjacent the head at the termination of the coiling operation, or that the wire is severed by cutters on the head. In the form shown in Fig. 1, the wire x is passed through a hollow handle a provided with an Archimedean screw thread a', and thence over a notch g, Fig. 2, in a head c, which is connected by links d to the handle. After passing round the bundle the wire is secured in the serrated slot g<1> in the head. The head is separated from the end of the handle by a spring e adjusted by a washer j. The head is first given a half turn so as to cross the wires and cause them to lie in the groove f in the head and is them rotated by a reciprocating nut b provided with spring pressed balls i, and the head is pressed up by the accumulating coils until the resistance of the spring exceeds the strength of the wire, whereupon the wire lying in the groove f across the head c is sheared off. The head may be held rigid during the initial crossing of the wires by arms u extending from the nut. A hand-operated spring catch may be provided to secure the handle to the nut. In a modification, Fig. 5, the wire may be severed after twisting by a pair of spring-opened cutter levers v', v<2> which are operated by a coned coller w' carried by a sleeve w<3> which is forced down by the engagement of the nut b with the levers w<1>, w<2> at the termination of its stroke. In the form shown in Fig. 3, the handle is pivoted at r in the bifurcated end of the head c, on which is mounted by a ball bearing l, a shield c<1>. The wire is passed through a pair of spring-closed conical jaws m, which in the position shown are held open by pins thereon engaging cam surfaces m<2> on the bifurcated end of the head. The wire then passes through rollers n, n<1> in a, cavity p in the handle, then through a perforation q<1> in the head, round the bundle and the end is passed through a slot s and secured by a clamp t to the head. A cam gripper q, mounted on a manually-operated spindle is out of action during this operation. The handle is then moved on its pivots so as to tighten the wire round the bundle, the motion of the handle causing the pins on the jaws m to be freed from the cam surfaces and to be closed on the wire by a spring, and the roller n<1> being carried by a spring-controlled arm so that it can fold back into a recess in the handle. The cam q is then operated to grip the wire and the handle returned to the position shown, prior to twisting the wires together by rotation of the head.

Filed: 1929-06-28
Abstract: 315,703. Buxton, W. R. July 16, 1928, [Convention date]. Card and like cases.- A case for cheques, bills, cards, &c. comprises an outer wall 20 and an inner wall consisting of two longitudinally-spaced end sections 25, 27 attached to the wall 20 along the folding line 24 and side edges 22, 221, and an intermediate section 30 which is free to move relatively to the outer wall and inner wall end sections and bridges the space between said sections. As shown the case is made from a pair of blanks, the section 30 being formed with a partition section 31 and slot 35 through which tabs 28 on the sections 27 are passed before being adhesively attached to the sections 25 when the section 27 are folded on to the sections 25 to form the tubular end sections of the inner wall. The partition 31 provides two cheque or bill compartments 36, 37 and pockets for cards &c. are formed between the sections 25, 30. When the case is folded along the transverse line 21 the intermediate section can move relatively to the other sections and prevent any buckling of the inner wall. The edges 22, 22<1> are connected by adhesive and are preferably skived as shown to give smooth thin edges to the case; the edges 22 may be formed with tongues to engage slits in the sections 25. The tabs 28 may be simply bent through the slot 35 and remain unattached to the sections 25. The sections 25 may be formed with ears 42 which, when the case is made up, hide and protect the corners of the partition 31. The partition section may be dispensed with and in this case the intermediate section is made long enough to ensure that it cannot be displaced sufficiently to permit either end to be pulled out of the corresponding tubular inner wall section: in this case the intermediate wall is provided with a pronounced transverse crease which as the case is closed works itself into the crease 21 upon which the case is folded.

Abstract: 186,760. Vivian, A. C. Aug. 5, 1921. Treating ores to facilitate concentration.-Ores containing the more valuable metals as oxygenccntaining compounds, for instance oxides or carbonates, are concentrated by a flotation process which consists in adding to the ore organic compounds, which are generally considered weakly acid but are amphoteric or display acipseudo forms, contain nitrogen and oxygen, and act upon the metals or metal compounds it is desired to concentrate forming tarry or resinous complexes or decomposition products under the conditions which commonlv occur in flotation processes, with or without the use of known oiling or frothing agents. In some cases this action is assisted by the presence of an oxidising agent, which may be the oxygen of the air used for frothing. Examples of these organic compounds, which may be added to or formed in the presence of the ore to be concentrated, are cupferron, oximes, iso-nitroso bodies, amido acids such as taurocholic acid, phenyl glyoxime, dinitroso resorcinol. The organic compound may also be formed by the reaction between ketones or aldehydes and hydroxylamine, nitrous oxide, or ammonia.
