Abstract

1440339 Binding metal J PALLISER 31 July 1974 [15 May 1973] 23090/73 Heading B3E Apparatus for bending pipes or other elongated articles of the kind comprising a former over which the article is bent and means for clamping the article at one side of the former in opposition to the bending force, includes means for locating in the bending plate of the apparatus a part of the article lying remote from an existing bend in it. In the embodiment shown in Fig. 1, the locating means has a frame 11 mounted to be pivotable about the former axis. A square rod 25 bearing locating indicia is slidable in block 19 and can be secured by screw 29, and supports channels 23, 24 suitable for two different size pipes. The selected channel is changed by dropping a round part 26 of rod 25 into block 19 so that the rod can be rotated. In Fig. 1 the device is inoperative, leg 21 resting on the bending machine, for a first bend to be made in a pipe. In Fig. 4c, the bent pipe has been located in the appropriate channel, the frame 11 tilted and locked by screw 34, Fig. 1, and rod 25 located in block 19 so that the pipe is correctly positioned for a second bend bringing the remainder of the pipe parallel with the portion lying in the channel to produce a double bend having an offset C-C as measured on rod 25. Alternative bending stops 18, 18<SP>1</SP>, Fig. 1, for the alternative pipe sizes may be used. The channels 23, 24 may be so positioned on rod 25 that one side of block 19 indicates the offset on rod 25 for one pipe size, and the other side for the other pipe size.
