IPC: B23K1/00
Filed: 1953-09-04
Abstract: 779,144. Tinning metals. LIBBEYOWENS-FORD GLASS CO. Sept. 4. 1953, No. 24451/53. Class 82(2) [Also in Group XXII] Metal strip coating apparatus comprises cleaning, fluxing, tinning and imprinting means. The metal strip 10 contained an a reel B is cleaned by brushes 56, wet brushed in chamber D, dried by air blasts at E, and then passes into a fluxing, tinning and oiling bath F insulated by thermal insulation 93. The strip is then washed in compartment G and air dried at H. The strip is now imprinted at I (see Group XXII) and recoiled at reel C. The strip is fed through the apparatus by rollers comprising abrasive discs. As described the strip is lead and therefore liable to melt in the tinning bath. To thread the strip a leader strip of sufficient length to extend through the molten bath to the coiling reel is stapled on to the lead strip. To facilitate threading the strip through the bath an arcuate trough 124 (see Fig. 5) is provided in the tinning bath 92 on the surface of which flux 100 and palm oil 102 is provided. Wipers 114 of rubber, and air jets 120, remove the sulplus oil from the strip. The bath is heated by electric heaters 96 under control of the thermostat 98. Specification 537,912 is referred to.

Heading F2E. In an internal shoedrum brake the brake shoes 3 are adapted to be applied by means of a cable operated resilient expander member 4 which is adapted to be expanded by actuation of the cable 20. The resilient member takes the form of two arcuate spring strips 14 held together at their ends by means of intermediate thrust elements 23. The brake illustrated in the figures is a duo-servo brake and in operation, when the cable 20 is drawn into a tube 19 the arcuate backs of the spring strips approach one another, the strips expand and force the shoe ends 7 apart so that each shoe 3 engages the drum surface 6. When the brake is released, the resilience of the two spring strips 14 pulls the head 18 and the cable 20 out of the tube 19 and returns the shoe ends 7 by means of bands 16, 16<SP>1</SP>. Manual adjustment is provided by a screw-threaded adjuster 5 (Fig. 1, not shown).

Creel. arrangements; spindle-driving apparatus. -An electric device for controlling the rotation of bobbins when winding thereon or therefrom comprises a shaft 12, Fig. 1, to which is rigidly fixed a disc 14 of conducting material, a circular magnet-frame 17 provided with a coil 15 to produce a magnetic field intersecting the disc, and an armature-member 19. The parts 17, 19 are free to rotate on the shaft 12 and are held together by a member 20 of non-magnetic material, the securing screws 21 of which work in elongated slots to permit angular adjustment. The spool is mounted between members 28, 29 on the shaft 12 which, normally, is rotated while the parts 17, 19 are held stationary by stops 27. The members 17, 19 may be rotated by means of a belt over a pulley 23, and the shaft 12 dragged round in consequence. One application of the device is shown in Fig. 4, wherein a wire 30 is being wound on a bobbin 34 from a spool 33 mounted on the shaft 12. When the shaft 35 carrying the bobbin 34 is rotated, the material 30 is tensioned to an extent depending on-the speed of rotation and the current through the coil 15 which latter may be regulated by the resistance 31. If it be desired to wind on the spool 33, the parts 17, 19 are rotated by a motor 24. A magnetically-operated brake 36 is provided to act on breakage of the material being wound, a slackening of the material 30 permitting a roller 38 to rise and to result in separation of the contacts 37 which causes the brake to act.
