Abstract
An adjustable hold down clip for use on apparatus using a reciprocating sickle, for maintaining the sickle in a stabilized, efficient shearing position relative to an underlying cutting surface by pivoting around a pivot member in response to the tightening or loosening of an adjustment nut which counteracts a lifting force imparted onto the clip by a tension member. The tension member is located between the pivot member and sickle, to provide lifting action away from the sickle and minimize drag on the reciprocating blade.
Claims8
In combination:
- a sickle bar mower having an elongated frame member and a sickle blade mounted thereon for reciprocating movement, said sickle blade projecting forwardly from said frame member and reciprocating transversely with respect thereto;
- an elongated base plate mounted to said frame member rearwardly of said sickle blade, said base plate having an upper surface and forward and rearward edges;
- means for adjustably and pivotably mounting a hold down clip to said base plate;
- a hold down clip having forward and rearward ends, said forward and rearward ends having bottom surfaces, said clip adjustably and pivotably connected to said frame member;
- said hold down clip forward end projecting forwardly over said sickle blade and having a wear pad on the bottom surface thereof for contact with said sickle blade;
- said means for adjustably and pivotably mounting said clip including:
- an adjustment bolt extending upwardly from said base and through said rearward portion of said clip and having one end projecting upwardly from said clip;
- an adjustment nut operably engaged on the projecting end of said bolt for selective upward and downward movement thereon;
- tensioning means interposed between said base plate and said clip for biasing said clip upwardly on said bolt against said adjustment nut;
- and
- a pivot member located rearwardly of said adjustment bolt about which said clip pivots upon selective movement of the adjustment nut;
- said pivot member including a depending portion depending from the rearward end bottom surface, having a pivot edge oriented transversely to a longitudinal axis of the clip about which the clip will pivot, said pivot edge in pivotal contact with said base plate.
