[Class 83 (iii).] An extensible die-head has means for locking a die plate assembly to a body part comprising a spring-pressed trigger pivoted to a ring freely rotatable on the barrel of a guide chuck carried by the die-head, the trigger passing through a guideway of the body and adapted to be set in a locking position slidably between faces on the body and the die assembly for locking the latter to the body. The die-head is in two main parts ; the body part a, Fig. 2, and the guide part n having self-centring chuck means o, p, these two parts being screw-connected ; the former carries the dies i radially adjustable by slot engaging cam-pieces k on a ring f. The ring f is adapted to be adjustably connected to the ring d by a screw-clamp 12, Fig. 1, the latter ring having a hollow lug 14 for one end of a compression spring 13, the other end engaging a lug on the body a, the spring serving to retract the dies as soon as the locking means release.

Abstract: 288,537. Barnum, T. E. April 11, 1927, [Convention date]. Automatic starters.-A starter of the kind used in conjunction with a compensator or autotransformer for starting an alternating current motor consists of two electromagnetically actuated switches mutually controlling each other's action. When the first switch is closed to connect the motor to the supply through reduced voltage taps it sets in motion a retarded relay which after a certain time energizes the electromagnet for closing the full-voltage switch. After this switch has made part of its closing movement it brings about the opening of the first switch and thus removes a mechanical interlock, allowing the closing movement of the full-voltage switch to be completed.
