Abstract

1381215 Threading tools COLLINS MACHINERY CORP 2 July 1973 [9 April 1973] 31354/73 Heading B3N A work threading tool comprises annular members 28 and 22 disposed coaxially for relative rotation, thread chaser means carried by a member to be advanced toward and retracted away from work received axially of said members in response to rotation of the members in opposite directions, operating means including a manually operable lever 41, and trip mechanism responsive to relative travel of the threaded work and the tool to predetermined relative positions to effect automatic displacement of the lever from its operating to its release position and consequent retraction of the chaser means. Chasers 25 engage in slots 26 in bosses 27 on member 22. The slots are forwardly open so that pins 38 on the chasers can engage in spiral slots 34 in member 22. Ring 30 holds the two members together. The trip mechanism is a lever 42 that when moved disengages shaft 47 from a spring-loaded plunger 50. The plunger moves lever extension 41a about its pivotal connection on a boss 74 integral with member 22. Setting of the chasers can be controlled by the positioning of a pin 66 in one of holes 67a-67d. Pin 66 is pivoted to lever 41. Fine adjustment is achieved by having the pivotal connection in lug 74 from the lever 41 as eccentric. Thus turning of head 78 controls fine movement of member 28 relative to member 22.
