Abstract
Abstract An elongated tubular arm of non-circular internal and external cross-sectional shape is provided and has a first elongated transverse jaw carried thereby and projecting outwardly of one side of the arm. The jaw defines a transverse non-circular opening in one end closely slidably receiving the arm therethrough for longitudinal shifting of the jaw along the arm. An elongated operator of non-circular cross-sectional shape is slidingly telescoped in the arm and a first end of the operator projects outwardly of the corresponding end of the arm. A second elongated transverse jaw has one end supported from the operator first end and projects outwardly of the side thereof corresponding to the aforementioned side of the arm in opposition to the first jaw. Actuator structure is operatively connected between the arm and the operator for shifting the operator toward a predetermined position relative to the arm in a direction retracting the first end of the operator relative to the corresponding arm end and the portions of the first jaw defining the transverse opening therein and the external surfaces of the arm along which the first jaw is slidable coact to frictionally lock the first jaw in shifted position along the arm in response to slight relative angular displacement of the first jaw and the arm about an axis transverse to the first jaw and arm.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
188 words
A log handle for engaging, supporting and lengthwise feeding log wood sections into a wood stove firebox, said handler including an elongated tubular arm, a first elongated transverse jaw carried by and projecting outwardly of one side of said arm and defining a transverse opening in one end closely slidably receiving said arm therethrough for longitudinal shifting of said jaw along said arm and frictional locking of said jaw in shifted position along said arm is response to slight relative angular displacement of said jaw and arm about an axis transverse to said arm and jaw, an elongated operator slidingly telescoped in said arm with one end thereof projecting outwardly of the corresponding end of said arm, a second elongated transverse jaw having one end supported from said operator and projecting outwardly of the side thereof corresponding to said one side of said arm in opposition to said first jaw, and actuator means operatively connected between said arm and operator for shifting said operator toward a predetermined position relative to said arm in a direction retracting said one end of said operator relative to said corresponding arm end.
Claim 2
Dependent Claim
188 words
A log handle for engaging, supporting and lengthwise feeding log wood sections into a wood stove firebox, said handler including an elongated tubular arm, a first elongated transverse jaw carried by and projecting outwardly of one side of said arm and defining a transverse opening in one end closely slidably receiving said arm therethrough for longitudinal shifting of said jaw along said arm and frictional locking of said jaw in shifted position along said arm is response to slight relative angular displacement of said jaw and arm about an axis transverse to said arm and jaw, an elongated operator slidingly telescoped in said arm with one end thereof projecting outwardly of the corresponding end of said arm, a second elongated transverse jaw having one end supported from said operator and projecting outwardly of the side thereof corresponding to said one side of said arm in opposition to said first jaw, and actuator means operatively connected between said arm and operator for shifting said operator toward a predetermined position relative to said arm in a direction retracting said one end of said operator relative to said corresponding arm end.
Claim 3
Dependent Claim
41 words
The combination of claim 1 wherein said actuator means includes a toggle link assembly including an over center position to which said toggle link assembly is shifted as a result of actuation thereof to shift said operator to said predetermined position.
Claim 4
Dependent Claim
31 words
The combination of claim 2 wherein said toggle link assembly includes an actuating lever disposed generally parallel to said arm when said toggle link assembly is in said over center position.
Claim 5
Dependent Claim
37 words
The combination of claim 1 wherein said tubular arm and actuator include complementary internal and cross-sectional shapes keying said operator to said arm against angular displacement of said operator about its longitudinal axis relative to said arm.
Claim 6
Dependent Claim
49 words
The combination of claim 1 wherein said arm includes a non-circular external cross-sectional shape and said opening in said first jaw is of a complementary cross-sectional shape whereby said first jaw is keyed to said arm against angular displacement relative thereto about an axis extending longitudinally of said arm.
Claim 7
Dependent Claim
37 words
The combination of claim 5 wherein said tubular arm and actuator include complementary internal and cross-sectional shapes keying said operator to said arm against angular displacement of said operator about its longitudinal axis relative to said arm.
Claim 8
Dependent Claim
17 words
The combination of claim 1 wherein said elongated jaws include outer ends which converge toward each other.
Claim 9
Dependent Claim
37 words
The combination of claim 7 wherein said tubular arm and actuator include complementary internal and cross-sectional shapes keying said operator to said arm against angular displacement of said operator about its longitudinal axis relative to said arm.
Claim 10
Dependent Claim
49 words
The combination of claim 8 wherein said arm includes a non-circular external cross-sectional shape and said opening in said first jaw is of a complementary cross-sectional shape whereby said first jaw is keyed to said arm against angular displacement relative thereto about an axis extending longitudinally of said arm.
Claim 11
Dependent Claim
41 words
The combination of claim 9 wherein said actuator means includes a toggle link assembly including an over center position to which said toggle link assembly is shifted as a result of actuation thereof to shift said operator to said predetermined position.
