Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
242 words
A belt tightening tool comprising: an elongated arcuate jaw element having a concave inner gripping face, a convex outer face and a pair of opposed, substantially parallel, flat side surfaces extending between said inner and outer faces; a lug-engaging to projecting from said jaw element at one end thereof; and elongated lever arm means having one end detachably and adjustably connected to said jaw element at a location intermediate the ends thereof, said elongated lever arm means comprising: an elongated lever arm; and a bifurcated connecting bracket which includes: a web portion secured to one end of said lever arm; and a pair of legs extending on opposite sides of said jaw element and adjustably connected to said jaw element; and further characterized in that said arcuate jaw element defines a plurality of pairs of spaced apertures extending therethrough from one of said side surfaces to the other; and each leg of said bifurcated connecting bracket defines a pair of spaced apertures, with the pairs of apertures in said legs aligned with each other, and the spacing of said apertures in said legs conforming to the spacing of said pairs of spaced apertures in said arcuate jaw element; and wherein said tightening tool further includes fastening means extending through aligned pairs of apertures in said legs and in said arcuate jaw element to secure said lever arm means to said arcuate jaw element at a selected angular relationship to said jaw element.
Claim 2
Dependent Claim
242 words
A belt tightening tool comprising: an elongated arcuate jaw element having a concave inner gripping face, a convex outer face and a pair of opposed, substantially parallel, flat side surfaces extending between said inner and outer faces; a lug-engaging to projecting from said jaw element at one end thereof; and elongated lever arm means having one end detachably and adjustably connected to said jaw element at a location intermediate the ends thereof, said elongated lever arm means comprising: an elongated lever arm; and a bifurcated connecting bracket which includes: a web portion secured to one end of said lever arm; and a pair of legs extending on opposite sides of said jaw element and adjustably connected to said jaw element; and further characterized in that said arcuate jaw element defines a plurality of pairs of spaced apertures extending therethrough from one of said side surfaces to the other; and each leg of said bifurcated connecting bracket defines a pair of spaced apertures, with the pairs of apertures in said legs aligned with each other, and the spacing of said apertures in said legs conforming to the spacing of said pairs of spaced apertures in said arcuate jaw element; and wherein said tightening tool further includes fastening means extending through aligned pairs of apertures in said legs and in said arcuate jaw element to secure said lever arm means to said arcuate jaw element at a selected angular relationship to said jaw element.
Claim 3
Dependent Claim
61 words
A belt tightening tool as defined in claim 1 wherein said toe is of substantially rectangular configuration and extends from said jaw element generally toward the center of curvature of said concave face from a location on said jaw element at one end of said concave face, said toe having a serrated side edge extending to, and intersecting, said concave face.
Claim 4
Dependent Claim
25 words
A belt tightening tool as defined in claim 2 wherein said concave face extends from said toe through an arc of at least about 90°.
Claim 5
Dependent Claim
142 words
A belt tightening tool comprising: an elongated arcuate jaw element having a concave inner gripping face, a convex outer face and a pair of opposed, substantially parallel, flat side surfaces extending between said inner and outer faces; a lug-engaging toe projecting from said jaw element at one end thereof; an elongated lever arm having a tapered end portion at one end thereof; a bifurcated connecting bracket which includes: a web portion secured to the end of said lever arm opposite said tapered end thereof; and a pair of legs extending on opposite sides of said jaw element and rigidly connected to said web portion; and means adjustably connecting said legs of said bifurcated connecting bracket to said jaw element for adjustably and selectively rigidly securing said lever arm to said jaw element at a selected angle with respect to said jaw element.
Claim 6
Dependent Claim
142 words
A belt tightening tool comprising: an elongated arcuate jaw element having a concave inner gripping face, a convex outer face and a pair of opposed, substantially parallel, flat side surfaces extending between said inner and outer faces; a lug-engaging toe projecting from said jaw element at one end thereof; an elongated lever arm having a tapered end portion at one end thereof; a bifurcated connecting bracket which includes: a web portion secured to the end of said lever arm opposite said tapered end thereof; and a pair of legs extending on opposite sides of said jaw element and rigidly connected to said web portion; and means adjustably connecting said legs of said bifurcated connecting bracket to said jaw element for adjustably and selectively rigidly securing said lever arm to said jaw element at a selected angle with respect to said jaw element.
Claim 7
Dependent Claim
168 words
A belt tightening tool comprising: an elongated arcuate jaw element having a concave inner gripping face, a convex outer face and a pair of opposed, substantially parallel, flat side surfaces extending between said inner and outer face facilitating the placement of said jaw element in a narrow space measured in a direction normal to said parallel flat side surfaces, said jaw element having a plurality of apertures extending therethrough between said side surfaces; a lug-engaging toe projecting from said jaw element at one end thereof; an elongated lever arm; and a bifurcated connecting bracket connecting said lever arm to said apertured arcuate jaw element and including: a web portion secured to one end of said lever arm; and a pair of apertured legs extending on opposite sides of said jaw element; and means extending through selected apertures in said legs and said jaw element for adjustably connecting said jaw element to said lever arm at a selected angle of extension of said lever arm from said jaw element.
Claim 8
Dependent Claim
168 words
A belt tightening tool comprising: an elongated arcuate jaw element having a concave inner gripping face, a convex outer face and a pair of opposed, substantially parallel, flat side surfaces extending between said inner and outer face facilitating the placement of said jaw element in a narrow space measured in a direction normal to said parallel flat side surfaces, said jaw element having a plurality of apertures extending therethrough between said side surfaces; a lug-engaging toe projecting from said jaw element at one end thereof; an elongated lever arm; and a bifurcated connecting bracket connecting said lever arm to said apertured arcuate jaw element and including: a web portion secured to one end of said lever arm; and a pair of apertured legs extending on opposite sides of said jaw element; and means extending through selected apertures in said legs and said jaw element for adjustably connecting said jaw element to said lever arm at a selected angle of extension of said lever arm from said jaw element.
