VOLATILE LIQUID KNIFE APPLICATOR
First Claim
1. A volatile liquid, knife applicator for applying volatile liquids to the soil comprising:
- a shank of rigid construction normally disposed in an upright manner;
a leading knife of rigid construction formed on the lower end of said shank and extending forwardly of said shank at an oblique angle;
side shields having a leading edge and a trailing edge secured to each side of said leading knife at said leading edge and extending rearwardly thereof;
said side shields being of substantially the same length as said leading knife;
a hose support member affixed between said side sHields, said hose support member being spaced above the lowermost ends of said side shields and proximate said trailing edges of said side shields; and
a flexible hose for carrying the volatile liquid extending downwardly between said side shields and forwardly of said hose support member, the end of said hose trailing said side shields a sufficient distance to prevent freezing temperatures at said side shields.

Abstract
A knife applicator for applying volatile liquids to the soil is provided herein. The knife applicator is comprised of a shank securable to a tool bar and a leading knife formed on the shank for opening a slit in the ground. Side shields extend rearwardly of the knife and a flexible hose extends downwardly between these shields. A hose support member is affixed between opposite side shields and maintains the hose in the ground. The hose extends rearwardly of the side shields a sufficient distance to prevent icing of the side shields. In a preferred embodiment, a link chain is secured above the hose and extends rearwardly of the hose to facilitate sealing the volatile liquids in the ground.
