Abstract: 824,924. Apparatus for assembling flanged drums. BRITISH INSULATED CALLENDER'S CABLES Ltd. March 19, 1956 [March 18, 1955], No. 8001/55. Class 99(2). Apparatus for use in the assembly of a drum comprising a barrel and a pair of flanges, comprises two pairs of spaced rollers 2 one for each flange 8 of the drum, each pair consisting of front and rear rollers having their axes parallel with each other and with those of the rollers of the other pair and pairs of guides 9, one pair for each pair of rollers, the guides of each pair being mounted to engage one on each side of a flange near the periphery of the flange and at a height sufficing to maintain the flange with its axis parallel or substantially parallel with the axes of the rollers supporting it. The flange can be rolled into engagement with the guides. Provision may be made for vertical adjustment of the cross-bar 7. For example a number of bott holes may be drilled in one of the uprights with corresponding holes in the other upright. The cross-bar may then be bolted to the uprights at any desired height, alternatively, or in addition, the height of the guides on the crossbar may be adjustable. The guides may be horizontally adjustable along the cross-bar. In an alternative form of construction (not shown) each pair of guides may be adjustably mounted on a comparatively short arm projecting inwards from each upright. In this arrangement the guide of each pair for engaging the inner side of the drum flange may be mounted on the end of the arm the arm being horizontally adjustable relative to the upright to a position appropriate to the drum width and the guide for the outer side of the flange being movable on the arm to vary the gap between the guides. If desired, the rollers of one or both pairs may be mounted to be movable in the direction of their axes to accommodate different drum widths and the guides associated with the movable rollers may be mounted on supports which are movable with the rollers so that the rollers and guides can be adjusted simultaneously. The cross-bar may be positioned to one side of the drum axis in which case the guides will engage the flanges at positions somewhat lower than in the other arrangement. Fig. 4 illustrates an alternative form of stand. The cross-bar 14 is adjustable along the slots in the arms 10 and it is preferable for the guides 15 to be mounted for pivoting about a horizontal axis. The guides may be set to engage flanges of any diameter within a given range by setting the arms at the appropriate angle adjusting the position of the cross-bar along the arms loosening the nuts 16 holding the cross-bar to the arms turning the cross-bar so that the guides project approximately towards the drum axis and tightening the nuts 16. The roller bed may be mounted for tilting as a whole or the rear roller may be mounted for lifting through the appropriate distance. The stand is suitable for use in assembly of wooden drums or of drums in which the flanges and/or barrel are of metal. There may be a clutch to connect together at least two of the rollers to prevent relative rotation of the flanges after they have been aligned. There may also be provided a brake to restrain the flanges against rotation.
