Filed:

Mar 30, 2000

Appl. No.:

09/539299

Inventors:

Joseph R. Hoepfl - Greenfield WI
Christopher D. Thompson - Milwaukee WI

Assignee:

Snap-on Technologies, Inc. - Lincolnshire IL

International Classification:

B29C 4514

US Classification:

264250, 264255, 264274, 264267

Abstract:

A driving tool, such as a screwdriver, has a handle with an injection-molded, relatively hard and rigid inner body, molded around a tool shank, the inner body having an elongated central portion with two end flanges extending laterally outwardly of the central portion around the entire periphery thereof, with the central portion having a peripheral groove formed therein adjacent to an end flange. An outer gripping body of a relatively soft and resilient material is injection molded around the inner body, by supporting the inner body by its ends in a mold cavity and injecting the mold charge adjacent to the groove so that it first fills the groove and then flows in a circumferential front longitudinally to the other end flange, surrounding said central portion of said inner body.

Appl. No.:

08/692711

Inventors:

Christopher D. Thompson - Milwaukee WI
Joseph R. Hoepfl - Greenfield WI

Assignee:

Snap-on Technologies, Inc. - Lincolnshire IL

International Classification:

B25B 1346

US Classification:

81 631, 192 432

Abstract:

A ratcheting driver handle has a ratchet body press-fitted axially in one end thereof, the body defining a socket which receives a gear for rotation coaxially with the handle. The socket also receives two pawls respectively disposed above and at opposite sides of the axis and spring-biased into engagement with the gear. A selector cap rotates on the housing and carries a first pin for driving the pawls respectively out of engagement with the gear, depending upon the direction of rotation, to control the ratchet direction. A second pin on the cap engages an over-center leaf spring mounted in the socket below the gear for resiliently retaining the mechanism in either of the forward or reverse conditions. A driver bit has a flattened end which is received through an axial bore in the cap and into a complementarily shaped bore through the gear for rotation therewith, being frictionally retained in place by a retaining ring.

International Classification:

B25B023/16

US Classification:

8117785, 811772, 81438, 279 38

Abstract:

A method and apparatus for coupling an attachable tool to a handle comprising a coupler device fixedly attached to the handle and having a locking structure moveable between locking and release conditions and being carried by a coupler body having an inner wall defining a cavity that is accessible via a cavity dimensioned and shaped to receive the attachable tool and having a first locking member for cooperative abutting engagement with the attachable tool to temporarily move the locking structure to its release condition when the attachment shaft is inserted into the cavity and a second locking member for cooperative engagement with the locking structure when the attachment shaft is inserted substantially into the cavity and the locking structure is moved to the locking position to inhibit removal of the attachment shaft from the cavity.

International Classification:

B25B 13/00
B25B 13/46

US Classification:

81 583, 81 62, 81 63

Abstract:

A ratcheting tool having an axial pawl ratcheting mechanism is provided that may be used for a screwdriver or wrench and comprises a first gear including axial gear teeth on a first side providing for ratcheting in a first direction. A second bidirectional gear has axial teeth on both sides. The second gear is mounted to the first side of the first gear so that the first gear axial gear teeth engage the second gear axial gear teeth and provide an axial pawl ratchet assembly. A ratchet head is provided having an opening for receiving the axial pawl ratchet assembly therein in order to transfer torque between the ratchet head and the axial pawl ratchet assembly. An actuator is provided for adjusting the positioning of the axial pawl ratchet assembly between a first position and a second position.
