Ratcheting driver with pivoting pawls and method of arranging same
View Patent ↗A ratcheting driver for rotationally driving a piece and having a handle and pivotal pawls engageable with a driven gear and being capable of ratcheting and driving in both rotational directions. A cap is rotatable relative to said handle and it has a web for pivoting the pawls out of engagement with the gear. Through the selective rotation of the cap, the setting of the pawls is established. A spring positions the pawls in driving positions, and the cap has surfaces which disengage the pawls from the gear upon rotation of the cap. A method of arranging the driver is included.
1. A method of arranging a ratcheting driver for rotationally driving a piece, comprising the steps of:
providing a handle with a hollow interior and a longitudinal axis and two pockets supported by said handle,
placing two pivotal pawls in said pockets for orbital motion about said axis,
attaching a cap relative to said handle for rotation of said cap relative to said handle and about said axis and with said cap having a web extending toward said axis and between said pawls for interference therewith to restrict the rotation of said cap and said cap having a hole extending through said cap and parallel to said axis and aligned with one of said pawls, and
having said one of said pawls spring-urged parallel to said axis and aligned with said hole through which there is access to said one pawl for depressing said one pawl and thereby releasing the interference and thereby the restricted rotation of said cap.
2. The method of arranging a ratcheting driver for rotationally driving a piece, as claimed in claim 1 , further comprising the step of:
initially positioning said web onto said one pawl for depressing said one pawl against said spring and then rotate and axially move said cap relative to said handle for consequent positioning said web between said pawls in assembling said cap relative to said handle.
3. A method of arranging a ratchet driver for rotationally driving a piece, comprising the steps of:
providing a combined handle and gear with a longitudinal axis and two pockets disposed by said handle,
placing two pawls in respective ones of said pockets for orbital motion about said axis,
attaching a cap relative to said handle for rotation of said cap relative to said handle and about said axis and with said cap having a web extending toward said axis and between said pawls for abutment with said pawls to restrict the rotation of said cap and said cap having a hole extending through said cap and providing access to one of said pawls, and
having said one of said pawls spring-urged parallel to said axis and aligned with said hole through which there is access to said one pawl for depressing said one pawl and thereby releasing the abutment and the restricted rotation of said cap.
4. The method of arranging a ratcheting driver for rotationally driving a piece, as claimed in claim 3 , further comprising the step of:
initially positioning said web onto said one pawl for depressing said one pawl against said spring and then rotate and axially move said cap relative to said handle for consequent positioning said web between said pawls in assembling said cap relative to said handle.
5. A method of arranging a ratchet driver for rotationally driving a piece, comprising the steps of:
providing a combined handle and a gear with a longitudinal axis and a hollow interior and with a cap rotationally disposed on said handle and having a projection thereon extending radially of said axis,
positioning two pawls to be pivotally supported by said handle adjacent said gear and being orbital about said axis upon and with rotation of said handle and with each of said pawls having teeth engageable with said gear for transmitting rotation from said handle to the piece and having one of said pawls axially movable relative to said handle,
positioning a spring operative on said one pawl for yieldingly axially urging said one pawl into rotational interference with said cap projection, and
arranging said cap for access to said one pawl for axially moving said one pawl out of rotational interference with said cap projection and thereby release said cap from said handle.
6. The method of arranging a ratchet driver for rotationally driving a piece, as claimed in claim 5 , further comprising the step of:
positioning said cap projection in axial contact with said one pawl for axially moving said one pawl and then subsequently rotating said cap to position said projection between said pawls and thereby arrange for the rotational interference.
7. In a method for arranging and operating a ratchet driver, the steps comprising:
providing a handle and a gear extending along a longitudinal axis for rotation about said axis and thereby driving a work piece,
disposing two pawls in said handle and having one of said pawls movable along said axis relative to said handle,
disposing a cap on said handle and being rotatable about said axis relative to said handle and with said cap having a portion in rotation interference with said one pawl for limiting rotation of said cap,
providing an opening on said cap for entry through said opening for axial contact with said one pawl, and
depressing said one pawl axially upon access through said opening for relieving the rotation interference and thereby provide for unrestricted rotation of said cap.
