Abstract

1340546 Bar stock feeds MERCER PNEUMATIC TOOLS Ltd 16 June 1972 [3 Aug 1971] 36471/71 Heading B3B [Also in Divisions B8 and F2] A bar feed mechanism comprises a feed tube 100 and a length of link chain, said chain being adapted to substantially fill the cross-section of the feed tube so that when in the tube it is constrained by the tube to prevent relative pivoting of the links and the chain becomes effective as a rigid rod usable for pushing the bar stock along the tube, and the mechanism includes feed means for feeding the chain into the feed tube. The mechanism further includes a storage tube 120 below and parallel to the feed tube 100 with the chain passing round a sprocket 102. The storage tube may include a further tube section below and parallel to the storage tube 120 with an idler sprocket passing the chain therebetween. The chain connects with a pusher bar 108 and pusher 110 in the feed tube 100. The end of the feed tube 100 is pivotable about the axis of the storage tube 120, relative to a fixed forward part 100A of the feed tube, to allow loading a bar into the said part 100A. The sprocket 102 may be manual and/or power driven. In one embodiment (Figs. 1-6, not shown) the chain is constructed of drum shaped links having annular part spherical parts for guiding in the tube, the said links being connected by link bars. In the second embodiment each link is formed from two halves each having a leading boss portion which extends between spaced apart sections at the rear of the adjacent link. The link halves are made from nylon or polypropylene to reduce noise and friction. The feed tube may be round or of other suitable cross-section depending on the section of the bar stock and the chain links are shaped accordingly. The sprocket 102 has particular form of teeth to push each link into the feed tube without a tendency to pivot. The tooth form comprises a dedendum defined by a circular arc having its centre on the pitch circle and an addendum defined by a circular arc of opposite curvature having its centre coincident with the centre of the dedendum of the next adjacent tooth.
