Abstract

632,389. Spring drums. McCAFFREYRUDDOCK TAGLINE CORPORATION. May 5. 1947. No. 12118. Convention date, March 18, 1941. [Class 78 (ii)] In crane mechanisms and the like a tagline device for maintaining under tension a line fastened to the load to prevent its turning is of the kind having a spring operated reel wherein the spring is interposed between the reel and a support and is characterised by the provision of connecting means for one or both ends of the spring operative to release the spring upon rotation of the reel ahead of the spring and to reconnect the spring upon reverse rotation. The spring 20 is thereby prevented from breaking when the tagline parts or becomes detached. Tho device also provides for supporting the cable of an electromagnet so that, as the tagline T, Fig. 2, is wound in on a reel 10, the cable C is wound in on a reel 11 of slightly smaller diameter. The two reels are bolted together and to a plate 13<SP>1</SP>, Fig. 3, having a hub bolted to a short shaft 13 at 13<SP>11</SP>. Shaft 13 is journalled in a bearing 14 bolted to a tubular housing 16 which may be secured to the boom of a crane &c. by U-bolts 18 and clamps 19, Fig. 2. Within the housing the end of shaft 13 is provided with a collar 15 on which a tube 21 is mounted to rotate with it, the other end of which is mounted on a collar 24 rotating on a stub shaft 22. Around tube 21 is coiled a spring 20 whose ends are provided with hooks 25, 26 normally engaging projections 27, 28 on collar 24 and fixed bearing 13 respectively. The projections have slanting portions 27b, 28b (not shown) at the opposite ends to those engaging hooks 25, 26 so that if collar 24 rotates ahead of the spring the hooks will ride over the projections preventing further uncoiling of the spring. The space between tube 21 and housing 16 is filled with lubricant. Enclosed in a housing 40 bolted to housing 16 are a pair of collector rings 30, 31 to collect current from brushes 38 and pass it to insulated bolts 33, 34 to which the ends of cables C are attached. A spring 42 coiled on shaft 13 within an insulating tube 41 bears against felt packing washers 43 to prevent lubricant from entering the collector housing.
