Abstract
8655. Dunbar, A., and Dunbar's Process, Ltd. May 13. R i v e t i n g.-In a machine f o r riveting metal hoops for casks, barrels, &c., the tool head is reciprocated by a slide through a weighted lever which is lifted by a crank or other device. The head G is carried by a plunger B and is reciprocated over anvils H secured to the frame A, by a rod K, which is connected at N to a lever L pivoted at M and weighted at 0 preferably by loose weights. The lever is raised by a roller R on a lever P, which is oscillated by a link T and crank U on a shaft V driven by worm gear from t h e driving shaft. The lever P is weighted at S to reduce the shock and strain of lifting t h e lever L. On one of the anvils is a slide h, Fig. 5, which is recessed at j and perforated to contain the rivet u which has been previously passed through holes in the hoop. The slide is then pressed by a foot-lever i into a position underneath the head G, which is then brought down to force the head of the rivet flush with the inner surface of the hoop, as shown in Fig. 4. The riveting operation is then performed on a snap q, Fig. 4, attached to the head or anvil which has a pointed cone-shaped centre r for spreading out the end of the rivet. The rivet end is centred under the die by a pair of notched scissor-like levers toothed at s which are normally closed by a weight c but are released before riveting commences by the head through levers l2, l1 and catch lever l4. The catch lever rests on a pin l5 on one of the levers l. In a modification, the levers s, s1 are pivoted on concentric shafts t1, t2, which are oscillated by bevel gear v1, v2, v3 from a shaft v4 which carries a weighted lever w2 operated by a cam-wheel w, which is intermittently rotated by the head through a link x3 and lever x1. The lever carries a pivoted catch x7 held in the position shown in Fig. 12 by a weight x6 having a pin x8 engaging the lever. The catch engages pins x on the wheel and slips past them on the return movement of the lever.
