Abstract
Abstract An implement tool bar has working tools connected to it and the tool bar is connected to the implement frame by a tool bar clamp including a pair of saddle members embracing the tool bar with a pair of spaced apart clamping plates rigidly connected at adjacent inner ends to one of the saddle members while a pair of bolts extend from the other saddle member on opposite sides of the tool bar to between the pair of clamping plates for rigid engagement therewith. A vertically disposed tool shank is clamped between the outer ends of the clamping plates which diverge outwardly from a spacing substantially equal to the thickness of the shank. Upon the outer ends of the clamping plates being drawn together uniform pressure is applied along the opposite sides of the shank to rigidly hold it in place.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
177 words
A tool bar clamp comprising, a pair of horizontally disposed L-shaped saddle members adapted to be disposed on opposite sides of a tool bar, a pair of vertically disposed spaced apart clamping plates having L-shaped notches formed in vertical edges of one end thereof and one of said L-shaped saddle members extending between said clamping plates and being matingly received in said L-shaped notches, weldment means rigidly connecting abutting edges of said pair of clamping plates to the exterior surface of said one L-shaped saddle member, a pair of bolts vertically spaced apart having ends positioned between said pair of clamping plates and rigidly connected thereto by weldments and extending from said clamping plates on opposite sides of said one saddle member with free ends of said bolts adapted to extend through openings in said other saddle member, and bolt means adapted to extend through the outer free ends of said clamping plates for drawing them tightly together against a vertically disposed tool shank adapted to be positioned between said outer free ends of said clamping plates.
Claim 2
Dependent Claim
177 words
A tool bar clamp comprising, a pair of horizontally disposed L-shaped saddle members adapted to be disposed on opposite sides of a tool bar, a pair of vertically disposed spaced apart clamping plates having L-shaped notches formed in vertical edges of one end thereof and one of said L-shaped saddle members extending between said clamping plates and being matingly received in said L-shaped notches, weldment means rigidly connecting abutting edges of said pair of clamping plates to the exterior surface of said one L-shaped saddle member, a pair of bolts vertically spaced apart having ends positioned between said pair of clamping plates and rigidly connected thereto by weldments and extending from said clamping plates on opposite sides of said one saddle member with free ends of said bolts adapted to extend through openings in said other saddle member, and bolt means adapted to extend through the outer free ends of said clamping plates for drawing them tightly together against a vertically disposed tool shank adapted to be positioned between said outer free ends of said clamping plates.
Claim 3
Dependent Claim
33 words
The structure of claim 1 wherein said free ends of said clamping plates flare outwardly and are adapted to be drawn together by said bolt means against spring action in said claMping plates.
Claim 4
Dependent Claim
49 words
The structure of claim 2 wherein the inner ends of said flared outer ends of said clamping plates are spaced apart the approximate width of a tool shank such that substantially uniform clamping pressure along said shank will be applied upon said bolt means drawing said clamping plates together.
Claim 5
Dependent Claim
31 words
The structure of claim 3 wherein the diameter of each of said bolts is equal to the spacing between the inner ends of the flared outer ends of said clamping plates.
Claim 6
Dependent Claim
55 words
The structure of claim 3 wherein the diameter of each of said bolts is larger than the spacing between the inner ends of the flared outer ends of said clamping plates and said clamping plates include inwardly converging portions between said bolts and the inner ends of said outer free ends of said clamping plates.
