Abstract

1,271,215. Jointing by stamping. C. C. WHITE. 19 Jan., 1970 [5 Feb., 1969], No. 2492/70. Heading B3Q. [Also in Divisions E1 and F2] In an embodiment for connecting two tie rods 126 together the rods extend through a sleeve 138 which is crimped about the rods after they have been tensioned by an hydraulic or pneumatic cylinder and piston unit which together with the crimping head is mounted on a mobile unit 142. A wedge box gripping unit 159 connected to the cylinder grips one rod end while the piston-rod engages the sleeve which is in contact with an enlargement on the other rod.
