  • Patent number: 3962953
    Abstract: A rotary tool holder of the type in which the tool has threaded engagement with a member projecting from a rotary body and the latter affords a forwardly directed radially extending locating face which engages a complementary face of the tool to locate the latter axially in use. In order to relieve the frictional engagement at such locating surface after the tool has been used, the member which is threadedly engaged with the tool is slidably received in a recessin the body and held initially in an axially retracted position, in which the tool engages the locating face, by means of a pair of grub screws engaging inclined faces afforded by a head portion of the member within said recess. When the grub screws are slackened, the member is allowed to move outwardly of the recess by an extent sufficient to relieve the frictional contact between the tool and the locating face so as to enable the tool threadedly to be unscrewed from a threaded member.
