Abstract

903,385. Jigs. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 12, 1959 [March 24, 1958], No. 9370/58. Class 83 (3). Apparatus for positioning a tool-holder centrally with respect to an existing hole in a workpiece comprises a head 1 which is connected to the tool-holder by a stem 5 and may be of the form described in Specification 769,978 for producing electrical signals in response to misalignment of the head, and a member 11 therein, and a spindle 3 connected to the member 11 by a universal joint 4 and carrying a gauge 2 to enter the hole a in the work b. A rod 12 carries a housing 5<SP>1</SP> having pins 8 for engaging the hole a, the pins being spring-urged at 10 against a conical-end 6 of the rod 12. In operation, the tool-holder (not shown) is moved up to the hole, the rod 12 is lifted into the spindle 3, thus freeing the pins 8, and the housing 5<SP>1</SP> is lowered into the hole. The pins 8 centralize the rod 12 in the hole, and if there is any misalignment between the hole and the head 1, the signal produced in the head will allow the tool-holder to be aligned manually, or the signal may be used in a system such as the one described in Specification 764,588, or any other servo-system for automatic adjustment of the tool-holder.
