Title: Transportable machine for tying up boxes
IPC: B65B13/28
Filed: 1928-01-27
Abstract: 286,246. Sapin, M. March 1, 1927, [Convention date]. Wire strainers.-A wire-binding machine for boxes, bales and packages adapted for use either with reels of wire or with wire in cut lengths is provided with means for tensioning the wire, automatically limiting the tension to a predetermined amount declutching the tensioning means and clutching the twisting means, twisting the wire and severing the free end, by operation of a single lever. The end of the wire is gripped between a block 25, Fig. 4, and a wedge lever 24 operated by a spring 23 when an eccentrically mounted shaft 3 is lowered by the partial rotation of a handle 26, Fig. 2. The wire is then inserted laterally into the slotted pinion 10, Fig. 7, and cutting device 42 when it rests clear of the puncher 43 on the right hand side of the gap shown in Fig. 6. It is then passed round the box or package, between a grooved pulley 44, Fig. 4, and milled wheel 18, Fig. 2, and again into the slotted pinion and cutter when it lies alongside the fixed end of the wire but disposed immediately below the puncher 43. A further partial rotation of the handle 26 further lowers the shaft 3 and causes the milled wheel 18 to grip the wire. A crank handle 4 is now oscillated causing rotation of the milled wheel 18 through the intermediary of a clutch 28, chain drive 5, 17a, 16, Figs. 2 and 3, and Belleville washers 17 which assist in preventing excessive strain on the wire. As soon as the tension on the wire reaches the desired limit, the increased tension of the chain 17a forces a guide pinion 36 downwards against the action of a spring 37 to move the clutch 28 out of engagement with the chain drive into engagement with a set of gears 6, 8. During one complete revolution of the gear 6, the gear 8 effects the twisting together of the wires in the slotted pinion and at the same time the cam 7 first depresses the punch 43 sufficiently to grip the free end of the wire and finally depresses it further to sever it. During the tensioning of the wire, the gear 6 is held stationary by a latch device engaging a cavity 39 in the gear, while during the twisting and severing operation the milled wheel 18 is held stationary by a ratchet 20. The milled wheel 18 may carry characters such as a trade mark on the periphery. The Specification as open to inspection under Sect. 91 (3) (a) refers also to modifications in which the automatic means for coupling the gears 5, 6 may be replaced by a hand device if desired, and in which the hand operated crank handlo 4 may be replaced by an electric motor giving a continuous drive. This subject-matter does not appear in the Specification as accepted.
