Title: Improvements in and relating to a method of and apparatus for the surface treatment of wire or like continuous stock
Inventor: DAVIDSON THOMAS WILLIAM
IPC: C23G3/02
Filed: 1957-10-24
Abstract: 898,746. Cleaning metals. ENGLISH ELECTRIC CO. Ltd. Oct. 24, 1958 [Oct. 24, 1957], No. 33295/57. Class 82(2). [Also in Groups VIII and XXXVI] An apparatus for treating e.g. cleaning the surface of a wire or like continuous stock by passing it through a liquid bath comprises a vessel and means for passing the wire or stock through a liquid contained in the vessel, said vessel having a pneumatic gland which is located below the normal surface level of liquid in the vessel and is adapted to permit the passage of the wire or stock from or into the vessel whilst gas supplied to the gland under a positive pressure flows from the gland to the vessel and so restrains liquid in the vessel from leaking through the gland. As shown, wire 10 is drawn vertically from spool 12 through pneumatic gland 13 which conducts it into treating liquid 11 contained in vessel 15, and is then wound-up on spool 14. Gland 13 consists of hollow tube 13a which is supplied with gas via pipe 13b. The ends of tube 13a are nozzleshaped so that the rim of each nozzle is a close yet loose fit to wire 10. Sealing ring 16 forms a connection between gland 13 and the base of vessel 15. In modifications, (a) the gland is movably attached to the vessel so that it may be caused to project into the vessel to different extents, (b) a number of wires are treated simultaneously by using a multi-headed gland, and (c) the apparatus comprises a number of vessels disposed one above the other or in a horizontal row, a series of glands being provided so that the wire may pass through each vessel without deflection. The apparatus may be used for the cleaning of wires, bars, strings and strips. The gas supplied to the gland may be inert (e.g. nitrogen) to prevent oxidation; alternatively, the gas may be heated to dry the wire surface, or the gas may be rendered humid to prevent such drying.

Belts, placing on and throwing off pulleys.-Relates to mechanism of the kind comprising a wheel such as 3 operated by a hand chain and carrying rollers for supporting the belt when idle and an arm for placing the belt on the pulley. There are two such rollers 5, Figs. 1, 2 and 3, close to the pulley rim and a. middle one 5<1> close to the centre, all carried on arms 4 secured to the wheel 3. From the rollers 5 5<1> arms 6, 8 extend radially to keep the idle belt from fouling the pulley. The wheel 3 rides on three fixed trunnions 2. The placing-on arm 9, which carries an inclined hand 10, Figs. 3 and 9, normally lies between two spring bolts 16, 17, Fig. 5, and is locked by them. The belt is moved off the pulley by a shifter comprising a rectangular sliding-rod 23 with roller-covered arms 25, 27 operated by'cords 30, 31. To place the belt on the pulley, a cord 32 is pulled which turns a lever 18, Fig. 5, so withdrawing the bolts 16, 17 and setting the arm 9 free. A pull on the chain 12 turns the wheel 3 bringing the hand 10 to the position shown in Fig. 9, the action being helped by moving the shifter 23 by a cord 30. When the wheel 3 has turned right round, the arm 9 strikes an incline on the bolt 16, Fig. 5, so that the bolt is thrust out of the way and snaps back behind the arm 9, locking it as at first. The wheel 3 carries a second socket 11, Fig. 1, for an additional placing-on arm, to meet the case of heavy belts.

A bobbin orientation device comprises a sequence of orientating elements as follows: 1. The tapered bobbins B fed in mass into a hopper 11 are delivered therefrom at 13 on to endless belt 15, the side frames 15a of which converge so as to position the bobbins in single file as shown. 2. Belt 15 feeds the bobbins slightly upwards on to endless belt 17, a guard 18 being provided so that any pair of bobbins jammed as at 18s are thrown upwards by belt 15 and, in striking guard 18, tip and fall over the side of belt 17. 3. The bobbins from belt 17 fall singly into the pockets 19a of endless belt 19. As the bobbins are conveyed upwards they encounter cam plate 21 which pushes over any vertical bobbins Bt so that they fall into a pocket. Next they encounter hold-down plate 23 pivoted at 23a which positions the bobbins relative to air nozzle 27. Any bobbins which are being conveyed with their thick ends on the right side of belt 19 will be engaged by the jet from nozzle 27 and will be hurled on to shoot 31 so that they slide theredown and fall back on to belt 15. The trajectory is made such that when fed forward again to belt 19 they will have the thick ends on the left side of belt 19. The latter belt thus discharges the bobbins orientated uniformly.
