Abstract: 837,489. Heat treating coils. UNITED ENGINEERING & FOUNDRY CO. May 17, 1957, No. 15769/57. Class 72 [Also in Group XXX] In apparatus for handling and cooling coils of rod the coils, which are wound on one or the other of two sets of reels 17, 18 from a rod mill 11 or 12, are pushed from the coiling positions on to tables 19, and thence in sets of four on to an intermittently driven conveyer consisting of an endless train of articulated carriages 26 each adapted to receive a coil. This conveyer transports the coils through a cooling tunnel 27 through which air is blown by fans 28, the conveyer being driven in one or the other direction according to whether reels 17 or 18 are in use. Beyond the cooling tunnel the conveyer extends through a further cooling zone where portable covers 31 may be placed over the coils to provide slow cooling as an alternative to the rapid cooling produced by the tunnel 27. After passing through this further cooling zone the coils are transferred in sets of four by a reciprocating pusher mechanism 32 on to another endless conveyer consisting of a train of articulated tiltable platforms 42 mounted on carriages 38 and are thence transferred to hooks 53 of an endless overhead conveyer 51. The coils are pushed individually from the reels 17 or 18 on to the tables 19 by reciprocating pushers 22 or 24, and are then transferred in sets of four from the tables 19 to the carriages 26 either by separate pushers 23 in the case of reels 17, or by a longer simultaneous pushing stroke of four of the pushers 24 in the case of reels 18. The pusher mechanism 32 for transferring sets of coils from the carriages 26 to the platforms 42 consists of a bar 34 extending alongside the path of carriages 26 and carrying four pivoted pusher heads 33 pivotally interconnected by a link 35. One end of the link 35 is pivoted to a pair of toggle links 36, 56 connected between the bar 34 and a stationary part 64 so that as the bar 34 is reciprocated across the path of the carriages the heads 33 are rocked to impart a part forward, part transverse pushing movement to the coils. The platforms 42 are pivoted at 49 to the carriages 38 and each includes an upstanding portion 44 and a rearwardly extending portion 45, the latter being equipped with a follower roller 46 engaging a stationary cam track 47 which is shaped to cause the platforms to tilt progressively to the Fig. 7 position and then return to level position as they pass along the portion of their path lying opposite the path of the hooks 53. In order that the hooks 53 may enter and receive the coils they are pivoted to the conveyer 51 and each hook is equipped with a follower roller 54 engaging a cam track 55, Fig. 9, which causes the hooks to swing away from the path of the platforms 42, Fig. 3, and then return to enter the coils as the platforms 42 are tilted, Fig. 7. The path of the conveyer 51 is arranged such that as the hooks 53 enter the coils they rise slightly and lift the coils from the platforms 42 as the latter return to horizontal position.
