Title: Improvements in or relating to apparatus for removing yarn remnants from bobbins
IPC: B65H73/00
Filed: 1955-05-31
Abstract: 769,290. Stripping waste from bobbins. FISCHER AKT.-GES., G. May 31, 1955 [May 31, 1954], No. 15672/55. Class 120 (3). A machine for stripping waste from bobbins and provided with radially displaceable stripping tools has the tools mounted so as to be pivotable in a plane parallel to the axis of a bobbin being stripped and has means for bringing the tools into resilient engagement. As the bobbin 4 is introduced by tongs 5, Fig. 1, the stripping tools are held retracted. Six tools may be employed, each comprising a stripping tooth 7 and holder 6 mounted in a slide block 8 by a pivot 6a. The blocks 8 are displaceable in grooves 8a and, when the upward movement of the bobbin 4 begins, the blocks 8 are moved inwards through the action of a cam 23 that rocks a lever 24 to lift a sleeve 20 thereby allowing rods 12 to rise under the influence of springs 16 to turn levers 11 associated with pins 18 on holders 6. A cam 33 co-axial with the cam 23 actuates a lever 35 to reciprocate a sleeve 31 connected through links 29 and pins 18 with holders 6 in order to pivot teeth 7 to follow the configuration of the bobbin 4. Co-axial with cam 33 are other cams suited to the contours of bobbins of different shapes; by means of handle 52 any of the other cams may be brought into operation after disengagement of a cam and follower by pressure on a handle 56. Another form of apparatus, Fig. 5, has stripping teeth 65 carried in housings 63 pivotable to the contours of a bobbin 4 under the influence of a cam 72. The teeth 65 are held against the bobbin 4 by springs 66 until the housings 63 are moved away from the bobbin by projections on a cam 71.

[Classes 83 (ii) and 83 (iv).] Making rods and tubes; piling.-In a process for producing an integral mass of metal from an aggregate of smaller pieces, the pieces are pickled to reduce impurities which prevent crystal grain growth, transferred in a non- injurious atmosphere to a furnace and heated to between the melting-point and the recrystallization point, and subjected, in a non- injurious atmosphere, to pressure to cause crystal grain growth across the boundaries of the particles to cause them to coalesce. Brass, bronze, tin, zinc, aluminium, steel or iron are pickled in a bath of copper sulphate to remove impurities and to coat the pieces with a covering of copper. The pieces are then coalesced in a steam-hydrogen atmosphere as described in Specifications 271,853 and 317,400, [both in Class 83 (iv), Metals, Working]. Squirting.-The mass may be extruded from the coalescing press in the form of rods, bars, angles, tubes, &c., the coalescing and the extrusion resulting from a single movement of the press. Scrap, consolidating.-If the pieces are composed of scrap they are formed into briquettes, preferably after pickling. If the metal is extruded in the form of a tube the briquette is formed with a central hole. Working at specified temperatures.-The coalescing is performed at a temperature between the melting-point and the recrystallization point. When coalescing metals with melting-point below 1100‹ F. a temperature near the melting-point is used to allow of the use of reduced pressure in the apparatus.
