Claim 4

Apparatus as in claim 1, wherein said tool holding aperture has at least one flat side.

Claim 5

Apparatus as in claim 3 wherein said tool holding aperture and said passageway at said second portion correspond in shape, said flat sides lying in respectively a common plane.

Claim 6

A ratchet tool handle of the type having a rotatable ratchet gear means, pawl means for selectively and operatively engaging with and disengaging from said ratchet gear means, and control means within an aperture of said handle for moving said pawl means into and out of engagement with said ratchet gear means, the improvement wherein: a cover plate extending across said aperture and having a slot therein, a slider in said aperture on an outer side of said cover plate and having a post extending through said slot, a yieldable detent plate connected to said post for sliding movement in said handle, and spring means connected to said post and disposed in operative engagement with said pawl means for selectively engaging and disengaging said pawl means with said ratchet gear means.

Claim 7

A ratchet tool handle of the type having a rotatable ratchet gear means, pawl means for selectively and operatively engaging with and disengaging from said ratchet gear means, and control means within an aperture of said handle for moving said pawl means into and out of engagement with said ratchet gear means, the improvement wherein: a cover plate extending across said aperture and having a slot therein, a slider in said aperture on an outer side of said cover plate and having a post extending through said slot, a yieldable detent plate connected to said post for sliding movement in said handle, and spring means connected to said post and disposed in operative engagement with said pawl means for selectively engaging and disengaging said pawl means with said ratchet gear means.

Claim 8

Apparatus as in claim 5 including detent means on a lower side of said cover plate and in operative engagement with said detent plate.

Claim 9

Apparatus as in claim 6 wherein said detent means comprise a pair of ridges, each proximate a respective end of and disposed transverse to said slot.

Claim 10

Apparatus as in claim 7 wherein said detent plate includes transverse convolutions proximate respecting ends thereof, said convolutions being parallel to and selectively yieldably engaging said respective ridges.

Claim 11

Apparatus as in claim 8 wherein said slider is movable through three positions, one of which comprises a central position in which each of said convolutions engage a respective ridge and said pawl means engage said ratchet gear preventing rotation thereof, in any direction, with respect to said handle.

Claim 12

Apparatus as in claim 9 including two side positions located respectively on opposite sides of said central position, one of said convolutions of said detent plate engaging at an inner side one of said ridges when said slider is in one of said side positions and another of said convolutions engaging, at an inner side, another of said ridges when said slider is in another of said side positions.

Claim 13

Apparatus as in claim 10 wherein said pawl means comprises two pawls, both of said pawls engaging said ratchet gear means when said slider is in said central position, and wherein one of said pawls engages said ratchet gear means and the other of said pawls is disengaged therefrom, when said slider is in one of said side positions to permit rotation of said ratchet gear means in one direction with respect to said handle and to prevent rotation thereof in another direction with respect to said handle.

Claim 14

A ratched tool handle of the type having a rotatable ratchet gear means, pawl means for selectively and operatively engaging with and disengaging from said ratchet gear means, and control means for moving said pawl means into and out of engagement with said ratchet gear means, the improvement wherein: said ratchet gear means includes a gear ring having teeth on an exterior side thereof, a passageway through said gear ring, and an inner sleeve in said passageway in fixed relation with said gear ring and having a tool holding aperture therein, said inner sleeve extending rearwardly of said gear ring for supporting said ring for rotation within said handle.

Claim 15

A ratched tool handle of the type having a rotatable ratchet gear means, pawl means for selectively and operatively engaging with and disengaging from said ratchet gear means, and control means for moving said pawl means into and out of engagement with said ratchet gear means, the improvement wherein: said ratchet gear means includes a gear ring having teeth on an exterior side thereof, a passageway through said gear ring, and an inner sleeve in said passageway in fixed relation with said gear ring and having a tool holding aperture therein, said inner sleeve extending rearwardly of said gear ring for supporting said ring for rotation within said handle.

Claim 16

Apparatus as in claim 12 wherein said handle includes a housing portion for said ratchet gear means and said control means, said housing portion having a forward mouth of lesser diameter than at least portions of said gear ring, and a rearward bore for supporting a rearward end of said inner sleeve.

Claim 17

A ratchet tool handle of the type having a rotatable ratchet gear means, pawl means for selectively and operatively engaging with and disengaging from said ratchet gear means, and control means for moving said pawl means into and out of engagement with said ratchet gear means, the improvement wherein: said ratchet gear means includes a gear ring having teeth on an exterior side thereof, a passageway through said gear ring, said passageway having a first cylindrical portion and a second portion defined by at least one flat side, an inner sleeve in said cylindrical portion of said passageway in fixed relation with said gear ring and having a tool holding aperture of at least one flat side therein, and said at least one flat side of said tool holding aperture lying in a common plane with said at least one flat side of said second passage portion.

Claim 18

A ratchet tool handle of the type having a rotatable ratchet gear means, pawl means for selectively and operatively engaging with and disengaging from said ratchet gear means, and control means for moving said pawl means into and out of engagement with said ratchet gear means, the improvement wherein: said ratchet gear means includes a gear ring having teeth on an exterior side thereof, a passageway through said gear ring, said passageway having a first cylindrical portion and a second portion defined by at least one flat side, an inner sleeve in said cylindrical portion of said passageway in fixed relation with said gear ring and having a tool holding aperture of at least one flat side therein, and said at least one flat side of said tool holding aperture lying in a common plane with said at least one flat side of said second passage portion.
