Abstract: 783,573. Reeling wire. STEIBER, S. I. July 18, 1955 [July 24, 1954], No. 20768/55. Class 120(2) A device for feeding and temporarily storing a reserve of wire in reeling wire on to or from a reel drum is characterized by the provision of a wire storage drum between the reel drum and the place from which the wire is drawn or to which it is being fed, the storage drum being adapted to receive or to deliver wire when the reel drum is stationary thus enabling the reeling operation to proceed unimpeded when the exchange of a wire bundle is necessary. A winding member may be provided between the storage drum and a reeling drum for the purpose of winding: wire on to or off the storage drum according to requirements so that a certain quantity of wire will be available in reserve on the storage drum. In the construction shown the device consists of a reel drum 1, a storage drum 2, a winding member in the form of an arm 3 and a roller 4 mounted thereon, and a differential gear 5, 6, 7, 8, all of these principle parts being arranged on a vertical shaft 9. The reel drum 1 may be locked to the shaft 9 or braked there against by means of a friction coupling 12, 14. The arm 3 of the winding member is secured to the gear wheel 5 of the differential gearing and this wheel may be locked to the shaft 9 by means of a claw coupling 16, 17 and the other bevel gear 6 of the differential gear is rotatably mounted on the shaft 9 and may be connected to the storage drum 2 through a claw coupling 18, 19. In reeling off a wire bundle from the reel drum as shown in Fig. 3 the wire 25 runs over the roller 4 on the arm 3 and thence to the storage drum 2 whereon a certain quantity of wire is assumed to be stored, the wire being then drawn off with the requisite force towards a reeling on plate. If, the arm 3 is locked on to the shaft 9 by couplings 16, 17 the wire will be reeled off the reel drum 1 to the same extent to which it is wound off and on to the storage drum 2. When the wire bundle on the drum 1 commences to run out and another bundle is to be connected to it the drum 1 is stopped and locked to the shaft 9 by means of coupling 12, 14 and the ends 21 of the old bundle and 23 of the new bundle are welded together. Whilst the drum 1 is stationary the pull in the wire will bring about a revolving movement of the arm 3 about the shaft 9 so that the roller 4 will wind off the lowermost turns from the drum 1 while winding wire on to storage drum 2 at the same time: The new wire bundle 24 is then laid on the reel drum 1 and the reeling operation continues. For laying wire on to the storage drum 2 coupling 16. 17 is disengaged and the coupling 18, 19 is engaged. When a pull is exerted on the wire running off the storage drum 2 this drum will rotate so as to entrain the gear wheel 6 through the coupling 18, 19 and the arm 3 will thus turn about the shaft 9 in a direction opposed to that of the storage drum 2. The reel drum 1 which now runs freely on the shaft 9 is compelled by the pull in the wire to rotate at a speed such as to deliver wire both for the storage on the drum and for a supply to the take up station. In a second embodiment the device is used as a take up device winding wire on to the drum 1 and in this embodiment the shaft 9 is driven through an electric motor.
