Volatile liquid knife applicator

Claim 2

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.

Claim 3

The volatile liquid, knife applicator of claim 1 wherein a flexible pulverizing means is secured to said hose support member.

Claim 4

The volatile liquid, knife applicator of claim 2 wherein said flexible pulverizing means is a link chain, said link chain extending rearwardly of said flexible hose.

Claim 5

The volatile liquid, knife applicator of claim 3 wherein said side shields are joined together at the lowermost ends thereof.

Claim 6

The volatile liquid, knife applicator of claim 4 wherein means for securing said shank to a tool bar are formed on said shank; and said leading knife is of substantially planar configuration.

Claim 7

The volatile liquid, knife applicator of claim 5 wherein said flexible hose trails said side shields by at least 5 inches.

Claim 8

In a device for applying volatile liquids to the soil comprising a support means, a tool bar, a volatile liquid storage tank, and volatile liquid regulating valves communicating with the tank, the improvement consisting of volatile liquid, knife applicators, each of said applicators comprising: a rigid, normally upright shank secured to said tool bar; a rigid leading knife formed on the lower end of said shank and extending forwardly of said shank at an oblique angle; side shields secured to each side of said leading knife 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 the trailing edges of said side shields; and a flexible hose for carrying the volatile liquid extending from the regulating valves 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, and a flexible pulverizing means secured to said hose support member and extending rearwardly of said flexible hose.

Claim 9

In a device for applying volatile liquids to the soil comprising a support means, a tool bar, a volatile liquid storage tank, and volatile liquid regulating valves communicating with the tank, the improvement consisting of volatile liquid, knife applicators, each of said applicators comprising: a rigid, normally upright shank secured to said tool bar; a rigid leading knife formed on the lower end of said shank and extending forwardly of said shank at an oblique angle; side shields secured to each side of said leading knife 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 the trailing edges of said side shields; and a flexible hose for carrying the volatile liquid extending from the regulating valves 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, and a flexible pulverizing means secured to said hose support member and extending rearwardly of said flexible hose.
