Seed confining attachment for a wheat drill
First Claim
1. An attachment for a tubular seed delivery boot of the type having a shovel with sides and a forward apex and a rearwardly directed bracket at the boot lower end and carried by a shovel drill machine for the continuous planting of seeds, said attachment comprising,a support structure for attachment to the boot bracket,side plates carried by the support structure and extending forwardly therefrom and interconnected at their forward ends by a cross pin located below the open end of the seed delivery boot,a deflector supported by said cross pin and disposed within the lower end of the boot, said deflector having a forwardly facing inclined surface so as to deflect seeds forwardly in the direction of travel of said boot, andmultiple plates and interconnecting links carried by said cross pin so as to dispose an uppermost plate below the deflector so as to act on gravitating seed to cause same to be forwardly deflected toward the lowermost surface of the furrough bottom substantially intermediate the shovel sides with seed deposit prior to return of displaced soil to the furrough.

Abstract
An attachment is disclosed for securement to the boot of an agricultural shovel drill machine. Support structure of the attachment is affixed to the back side of the boot and serves to position a seed deflecting body proximate the discharge end of the boot which body serves to deflect the gravitating seeds forwardly. Plates also carried by the support structure act on the gravitating seed to expedite deposit of the seed in the lowermost portion of the furrow to enchance seed germination. The plates are loosely joined so as to automatically compensate for wear of the boot carried shovel and also to prevent clogging by soil. A handle is associated with the deflector body to permit positioning of same relative to the upright boot axis to enable desired seed deflection.
