Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
115 words
A reversing ratcheting wrench comprising: a wrench body having a handle portion at one end and a socket receiving portion at the other end; a ratchet gear rotatably mounted in said socket receiving portion; a pawl pivotally mounted in said body for oscillatory movement relative to said ratchet gear; a first spring means pivotally connected to said pawl for forcing the pawl into engagement with the ratchet gear; a push rod pivotally connected to said first spring means; a second spring means operatively connected to said push rod forcing said rod outward toward the end of said handle portion; a reciprocating operating piece operatively connected to said push rod for selective engagement of said pawl.
Claim 2
Dependent Claim
115 words
A reversing ratcheting wrench comprising: a wrench body having a handle portion at one end and a socket receiving portion at the other end; a ratchet gear rotatably mounted in said socket receiving portion; a pawl pivotally mounted in said body for oscillatory movement relative to said ratchet gear; a first spring means pivotally connected to said pawl for forcing the pawl into engagement with the ratchet gear; a push rod pivotally connected to said first spring means; a second spring means operatively connected to said push rod forcing said rod outward toward the end of said handle portion; a reciprocating operating piece operatively connected to said push rod for selective engagement of said pawl.
Claim 3
Dependent Claim
147 words
A reversing ratcheting wrench comprising: a wrench body having a handle portion at one end and a socket receiving portion at the other end; a ratchet gear rotatably mounted in said socket receiving portion; a pawl pivotally mounted in said body for oscillatory movement relative to said ratchet gear; a shaft pivotally connected to said pawl; a first spring biasing means operatively connected to said shaft urging said shaft toward the pawl for forcing the pawl into engagement with the ratchet gear; a push rod pivotally connected to said first spring biasing means; a second spring biasing means operatively connected to said push rod for forcing said rod toward the end of said handle portion; a reciprocating operating piece having a finger piece at one end and a locking hook at the other end, pivotally connected to the push rod; locking means for engaging such locking hook.
Claim 4
Dependent Claim
147 words
A reversing ratcheting wrench comprising: a wrench body having a handle portion at one end and a socket receiving portion at the other end; a ratchet gear rotatably mounted in said socket receiving portion; a pawl pivotally mounted in said body for oscillatory movement relative to said ratchet gear; a shaft pivotally connected to said pawl; a first spring biasing means operatively connected to said shaft urging said shaft toward the pawl for forcing the pawl into engagement with the ratchet gear; a push rod pivotally connected to said first spring biasing means; a second spring biasing means operatively connected to said push rod for forcing said rod toward the end of said handle portion; a reciprocating operating piece having a finger piece at one end and a locking hook at the other end, pivotally connected to the push rod; locking means for engaging such locking hook.
Claim 5
Dependent Claim
151 words
A reversible ratching wrench having a handle portion at one end and a socket receiving portion at the other end said socket receiving portion having a ratchet gear rotatably mounted therein and a pawl pivotally mounted therein for oscillatory motion with respect to said ratchet for selectively engaging said ratchet gear; wherein the improvement comprises: a shaft pivotally connected to said pawl; a first spring biasing means operatively connected to said shaft urging said pawl into engagement with the ratchet gear; a push rod pivotally connected to said first spring biasing means; a second spring biasing means operatively connected to said push rod urging said push rod toward the end of the handle portion; a reciprocating operating piece having a finger piece at one end and a locking hook at the other end, such operating piece being pivotally connected to the push rod and locking means for engaging such locking hook.
Claim 6
Dependent Claim
151 words
A reversible ratching wrench having a handle portion at one end and a socket receiving portion at the other end said socket receiving portion having a ratchet gear rotatably mounted therein and a pawl pivotally mounted therein for oscillatory motion with respect to said ratchet for selectively engaging said ratchet gear; wherein the improvement comprises: a shaft pivotally connected to said pawl; a first spring biasing means operatively connected to said shaft urging said pawl into engagement with the ratchet gear; a push rod pivotally connected to said first spring biasing means; a second spring biasing means operatively connected to said push rod urging said push rod toward the end of the handle portion; a reciprocating operating piece having a finger piece at one end and a locking hook at the other end, such operating piece being pivotally connected to the push rod and locking means for engaging such locking hook.
