Abstract

A flexible earth-working tine is releasably fastened to a transverse tool bar by use of a pair of identical clamping parts, a keeper element and releasable fastening means. The clamping parts are disposed on vertically opposite sides of the tool bar and have corresponding front ends with aligned vertical openings to receive a bolt extending downwardly therethrough, the bolt also connecting with the mounting end of the flexible tine. Corresponding rear ends of the clamping parts are maintained in assembled relationship by a keeper element and the flexible tine extends from its mounting end in encircling relation to the tool bar with an upwardly extending portion passing between transversely spaced fingers extending rearwardly from the upper and lower clamping parts. The upwardly extending portion of the earth-working tine disposed between the fingers serves to maintain the keeper element in its operative position on the fingers. The rearwardly extending fingers of the clamping parts prevent transverse movement of the tine and a single fastening bolt, with its cooperating nut, maintains the earth-workig tine and clamping parts in rigid clamped relation on the tool bar.

Clamping arrangement for releasably connecting a flexible earth-working tine to a transverse tool bar of quadrangular cross section with a first pair of sloping side walls converging upwardly and a second pair of sloping side walls converging downwardly, said clamping arrangement comprising:

a first clamping part having
a first segment at its front end presenting a vertical opening,
a second segment extending upwardly and rearwardly from said first segment in thrust transmitting engagement with one of said first pair of side walls,
a third segment extending downwardly and rearwardly from said second segment in thrust transmitting engagement with the other of said first pair of side walls, and
a rear segment having a pair of transversely spaced fingers defining a rearwardly opening notch;
a second clamping part having
a first portion at its front end presenting a vertical opening in alignment with said vertical opening in said first clamping member,
a second portion extending downwardly and rearwardly from said first portion in thrust transmitting engagement with one of said second pair of said walls,
a third portion extending upwardly and rearwardly from said second portion in thrust transmitting engagement with the other of said second pair of side walls, and
a rear portion having a pair of transversely spaced fingers defining a rearwardly opening notch in vertically aligned relation with said notch on said rear segment of said first clamping part;
a keeper element having a downwardly facing surface in thrust transmitting engagement with the top side of said rear segment of said first clamping part and an upwardly facing surface in thrust transmitting engagement with the bottom side of said rear portion of said second clamping part;
a mounting end of said tine presenting a vertical opening in alignment with said vertical openings in said clamping parts;
a curved sector on said tine extending from said mounting end rearwardly beneath said second clamping part thence upwardly through said notches and between said pairs of fingers thence forwardly in upwardly spaced relation over the top of said first clamping part thence downwardly in forwardly spaced relation in front of said clamping parts;
and,
releasable fastening means rigidly securing said mounting end of said tine to said clamping parts including a tension element extending through said openings.
