Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
165 words
A serviceable, releasable socket retaining ratchet, comprising: drive lug means for transmitting torque to said socket; ratchet means for reversibly ratchetably rotating said drive lug means; totally removable retaining means for selectively coupling said socket to said drive lug means; said retaining means comprising latch means for biasing a nose against the interior of said socket; said retaining means further comprising button means for releasing the bias upon said latch member; said latch means including said drive means having a longitudinal internal aperture provided with a cam surface at an end proximal to said socket; said latch means having a shank member passing through said internal aperture; said shank member having a pivotal coupling to said button means; and said shank member further having a head provided with said nose disposed to selectively contact said socket and also having a cam follower surface disposed to contact said cam follower surface when said button means is released so that said nose is biased toward said socket.
Claim 2
Dependent Claim
165 words
A serviceable, releasable socket retaining ratchet, comprising: drive lug means for transmitting torque to said socket; ratchet means for reversibly ratchetably rotating said drive lug means; totally removable retaining means for selectively coupling said socket to said drive lug means; said retaining means comprising latch means for biasing a nose against the interior of said socket; said retaining means further comprising button means for releasing the bias upon said latch member; said latch means including said drive means having a longitudinal internal aperture provided with a cam surface at an end proximal to said socket; said latch means having a shank member passing through said internal aperture; said shank member having a pivotal coupling to said button means; and said shank member further having a head provided with said nose disposed to selectively contact said socket and also having a cam follower surface disposed to contact said cam follower surface when said button means is released so that said nose is biased toward said socket.
Claim 3
Dependent Claim
54 words
A ratchet in accordance with claim 1 wherein said button means comprising: a button lying within said longitudinal internal aperture; said button having said pivotal coupling to said shank member; and spring means for biasing said button away from said socket so that said cam follower surface is thereby biased toward said cam surface.
Claim 4
Dependent Claim
36 words
A ratchet in accordance with claim 2 wherein said button further having a portion protruding from said ratchet so that said button can be manually depressed to separate said cam follower surface from said cam surface.
Claim 5
Dependent Claim
24 words
A ratchet in accordance with claim 3 wherein said spring means comprising a compression spring located between said button and said drive lug means.
Claim 6
Dependent Claim
75 words
A ratchet in accordance with claim 4 wherein said pivotal coupling comprising: said button having a lateral aperture in said protruding region; said shank member having an aperture in an end remote from said cam follower surface; and a pin passing through both said button aperture and said shank aperture so that the removal of said pin permits said button, said spring and said shank member to each be removed from said longitudinal internal aperture.
Claim 7
Independent Claim
92 words
A method of releasably retaining a socket mounted on a drive lug of a socket-type ratchet wrench, comprising the steps of: pivotally suspending a shank member centrally disposed within said drive lug of said wrench from a button member; providing said shank member with a nose portion disposed to contact the interior of said socket; and biasing said button member to contact a cam follower surface of said shank member against a cam surface of said drive lug so that said nose portion is thereby biased against the interior of said socket.
Claim 8
Independent Claim
92 words
A method of releasably retaining a socket mounted on a drive lug of a socket-type ratchet wrench, comprising the steps of: pivotally suspending a shank member centrally disposed within said drive lug of said wrench from a button member; providing said shank member with a nose portion disposed to contact the interior of said socket; and biasing said button member to contact a cam follower surface of said shank member against a cam surface of said drive lug so that said nose portion is thereby biased against the interior of said socket.
Claim 9
Dependent Claim
51 words
A method of releasably retaining a socket in accord with claim 6, further comprising the step of depressing said button member to space said cam follower surface from said cam surface to release the bias on said nose portion against the interior of said socket so that said socket is released.
