Method of making a torque tool handle
View Patent ↗A torque tool handle for releasably holding a driven shank, such as a screwdriver bit. The handle is elongated and has an opening with a sleeve therein carrying a detent and an actuator which is slidable on the sleeve for alternate locking and release of the detent relative to the shank disposed in the sleeve. There can be two handle openings at right angles to each other and with each having a sleeve and an actuator and a detent, so the handle is both an axial and a T-handle driver.
1. A method of making a tool which replaceably receives the shank of a driven tool, the steps comprising:
providing a handle with an opening having a longitudinal axis and a terminal open end,
providing parts for a first sub-assembly of a sleeve, an actuator, and a ball and with said sleeve having a longitudinal axis and an interior opening extending along said sleeve axis and a radially disposed opening extending through said sleeve and into said interior opening,
assembling said parts by placing said ball into said sleeve radial opening and placing said actuator onto said sleeve to be slidable thereon along said sleeve axis and having a surface on said actuator in contact with said ball for radially inward movement of said ball into said interior opening, for the driven tool locked mode, and said actuator arranged with a relief axially spaced from said surface on said actuator for radially outward movement of said ball, for the driven tool unlocked position, and
inserting said sub-assembly into said handle opening through said open end and have said actuator against a spring in said handle opening and positioning said sleeve in said handle opening in a fixed position for movement of said actuator along said sleeve axis to thereby radially move said ball and to have said actuator in contact with said spring for urging said actuator in a direction toward said terminal end.
2. The method of making a tool, as claimed in claim 1 , wherein:
said fixed positioning of said sleeve is aided by the application of knurling on the exterior of said sleeve and then pressing of said sleeve into said opening.
3. The method of making a tool, as claimed in claim 1 , wherein:
forming said handle opening and said sleeve is in a cylindrical shape with an exterior circular surface on said sleeve,
forming a groove on said sleeve surface and having said groove extend thereon in the longitudinal direction, and
forming said actuator with a portion placeable in and extendable along said groove and free of extending beyond said exterior circular surface and with said portion including said actuator surface and said actuator relief.
4. The method of making a tool, as claimed in claim 1 , including:
providing said handle with a second opening which extends transverse to said longitudinal axis, and
inserting a second sub-assembly similar to said first sub-assembly into said handle second opening and against a second spring in said handle and having the sleeve of said second sub-assembly in a fixed position on said handle and having said actuator of said second sub-assembly against said second spring and being movable to control the ball of said second sub-assembly.
