Abstract: 1,269,717. Loading and unloading stranding machines. M. MARTINEZ. 18 May, 1970 [23 May, 1969], No. 26489/69. Heading D1T. Full bobbins of wire are loaded onto, and empty bobbins unloaded from, a stranding machine by placing the full bobbins onto carriages movable along an endless track located above the machine whilst it is operating, and locating the bobbins at predetermined positions on the track, stopping the machine, unloading a plurality of empty bobbins from the machine, lowering a part of the track towards the machine to deposit full bobbins into bobbin support means in the machine, releasing the full bobbins from the lowered carriages, and raising the track part to re-form the track, bringing further carriages onto the track part and repeating the procedure until all spools have been changed.  The machine shown in Figs. 8 and 9 has a stranding unit 99 comprising 24 spools arranged in parallel pairs. Above each spool lies a run 118 of an endless track, a portion of which can be raised or lowered by means of screw jacks 127, motor 129, and yokes 126. A second, fixed, track 117 runs above the first and carries trolleys 122 driven by an endless chain 123. Trains of trolleys 130 run on the lower track, the leading trolley of each train having a drive member 133 engageable with the chain 123, and disengageable therefrom by a stop 134, to stop the train vertically above the stranding unit. These trolleys 130 support spool carriers 131 having forks 132 which are engageable with the flanges of the spools. In operation, trains of empty spool carriers are aligned with the machine, which is stopped with the exhausted spools uppermost. The carriers are lowered by lowering the track 118, releasing spool retaining latches 114, and actuated to grasp the spools, which are lifted from their supports by raising of the track. The train of carriers holding empty spools is advanced, and a train bearing full spools takes its place, the full spools being lowered onto pintles 107 by lowering of track 118. The stranding unit is then rotated through 180‹ for replacement of the other set of exhausted spools. Instead of being withdrawn by a train of empty spool carriers, in another embodiment the exhausted spools are released whilst in the bottom position to fall onto a conveyor. Loading the Spool Carrier Fig. 10 shows apparatus comprising a pair of chains 137 carrying spool support members by means of which spools are lifted and oriented with their axes vertical. A ram 141 then lifts the spools into engagement with the forks 132 of a bobbin carrier 131.

In a cylinder grinding machine comprising a wheelhead carrying a rotatable grinding wheel, and two spaced supports between which a workpiece to be ground is mounted for presentation to the grinding wheel, one of the workpiece supports 1 is carried by a mounting 2 through the medium of a resiliently flexible hinge 10 so that the support is movable relative to the mounting to shift one end of a mounted workpiece relative to its other end and so apply a taper adjustment, and means are provided for moving the workpiece support relatively to its mounting in controlled fashion. In the machine described, the support is a tailstock 1 mounted on the mounting 2 via a cross-strap hinge 10. The hinge comprises two parts each consisting of an elongate strip 11a or 12a bolted to the mounting 2 and tailstock 1 respectively and a series of regularly spaced lugs 11b, 12b projecting from one edge of the respective strip and bolted to the corresponding other member, the lugs being interfitted. A plunger 17 screw-threaded in the tailstock 1 bears at its lower end against the mounting 2 so that rotation of the plunger in the appropriate direction causes the tailstock to pivot anti-clockwise about the axis of hinge 10 and so move the workpiece horizontally towards the grinding wheel. Rotation of the plunger in the opposite direction allows the tailstock to return under its own weight and the action of the resilience of the hinge. The plunger 17 carries a component 19 having a pair of radial arms one of which is engaged by an adjusting screw threaded into the tailstock 1 and rotatable to rotate the plunger in one direction, and the other of which is engaged by a compression spring to return the plunger. Instead of the above arrangement the tailstock may be moved hydraulically. The tailstock supports a centre by means of a spring-loaded sleeve 5 which can be moved axially be means of a rack-and-pinion, 7, under control of a handle 9. The mounting 2 is slidable on a table 3 which is itself slidable on the machine bed to move the workpiece axially relative to the grinding wheel.
