Abstract

27,794. Bradley, W. M., and Geddes, J. Dec. 11. Outline gauges; gauging relative positions of pipes at joints.-Apparatus for setting or fitting the flanges or threaded ends of pipe connexions comprises adjustable flanges or threaded ends 16, Fig. 1, mounted on movable carriages 15 arranged at each end of a vertically adjustable table 8, upon which is first placed a wire templet 1 for setting the flanges or threaded ends 16 and subsequently the pipe, the flanges or ends of which are to be shaped to the templet. The templet 1 is bent or shaped to the contour of the required pipe, and the loose flange 2 at each end is brought to the proper inclination and rotated until the bolt holes set fair to the connexion at the work. The lock-nut 7, Fig. 8, is then tightened to jam the split cone 6 into the hub 4 to grip the templet. The templet may consist of a wooden batten made up of a number of slotted slats 10, Fig. 1, coupled together by bolts 11, and the flanges may be carried by wires 14 connected to each end of the batten, by universal joints or the like. The legs of the table are adjustable as to height and are jointed at their upper and lower ends. The carriages each comprise a bed-plate 20 carried by castors 21, which may be raised to allow the bed-plate to rest on the floor after the carriage is in a suitable position. Means are provided on the carriage to allow the flanges or threaded ends to be travelled horizontally and vertically and to be swivelled on to the bed-plate, and the flange is carried. by a pivoted arm 29, the inclination of which is adjusted by worm gearing 32. In the modification of the templet shown in Fig. 9, the threaded end 34, corresponding to the threaded end of the pipe, is connected to the wire in the same way as the flange shown in Fig. 8.
