Abstract
Abstract A means and method for treating trees, wherein a manually portable motor driven drill is utilized to drill holes in trees in a downwardly declining direction, and wherein fluid is injected into said holes after they are drilled, and may be partially filled with treating fluid by injecting the fluid through a passage in the drill used to drill the hole.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
166 words
A drill for drilling holes in trees and injecting liquid into said holes comprising: said drill having a cutting end; said drill having a central body portion; a helical auger structure projecting radially outward from said central body portion; said auger structure having a plurality of helical convolutions said convolutions having a first side generally facing said cutting end and a second side opposite to said first side; a liquid conducting tube secured to said drill adjacent said first side of said auger structure; said tube having a liquid delivery opening in the proximity of said cutting end of said drill; said cutting end having a cutting edge portion; said cutting edge portion disposed at said second side of said helical auger structure; an enlarged diameter stop collar is provided with a bore surrounding said helical auger structure; a set screw, threaded in said collar and engaging said body portion for fixing said collar on said body portion in various positions spaced from said cutting end.
Claim 2
Dependent Claim
166 words
A drill for drilling holes in trees and injecting liquid into said holes comprising: said drill having a cutting end; said drill having a central body portion; a helical auger structure projecting radially outward from said central body portion; said auger structure having a plurality of helical convolutions said convolutions having a first side generally facing said cutting end and a second side opposite to said first side; a liquid conducting tube secured to said drill adjacent said first side of said auger structure; said tube having a liquid delivery opening in the proximity of said cutting end of said drill; said cutting end having a cutting edge portion; said cutting edge portion disposed at said second side of said helical auger structure; an enlarged diameter stop collar is provided with a bore surrounding said helical auger structure; a set screw, threaded in said collar and engaging said body portion for fixing said collar on said body portion in various positions spaced from said cutting end.
Claim 3
Dependent Claim
46 words
The invention, as defined in claim 1, wherein: said stop collar is provided with a rounded peripheral portion adapted to abut the side of a tree trunk when said drill is rotatably projected thereinto in a downward incline relative to said side of said tree trunk.
Claim 4
Dependent Claim
204 words
A drill for drilling holes in trees and injecting liquid into said holes comprising: said drill having a cutting end; said drill having a central body portion; a helical auger structure projecting radially outward from said central body portion; said auger structure having a plurality of helical convolutions; said convolutions having a first side generally facing said cutting end and a second side opposite to said first side; a liquid conducting tube secured to said drill adjacent said first side of said auger structure; said tube having a liquid delivery opening in the proximity of said cutting end of said drill; said cutting end having a cutting edge portion; said cutting edge portion disposed at said second side of said helical auger structure; a stop collar is disposed on said body portion and spaced from said cutting end; said stop collar provided with a rounded peripheral portion adapted to abut the side of a tree trunk when said drill is rotatably projected thereinto at a downward incline relative to said side of said tree trunk; said collar having a chip relief opening therein; said opening communicating with a space between said tube and said second side of a respective convolution of said auger structure.
Claim 5
Dependent Claim
204 words
A drill for drilling holes in trees and injecting liquid into said holes comprising: said drill having a cutting end; said drill having a central body portion; a helical auger structure projecting radially outward from said central body portion; said auger structure having a plurality of helical convolutions; said convolutions having a first side generally facing said cutting end and a second side opposite to said first side; a liquid conducting tube secured to said drill adjacent said first side of said auger structure; said tube having a liquid delivery opening in the proximity of said cutting end of said drill; said cutting end having a cutting edge portion; said cutting edge portion disposed at said second side of said helical auger structure; a stop collar is disposed on said body portion and spaced from said cutting end; said stop collar provided with a rounded peripheral portion adapted to abut the side of a tree trunk when said drill is rotatably projected thereinto at a downward incline relative to said side of said tree trunk; said collar having a chip relief opening therein; said opening communicating with a space between said tube and said second side of a respective convolution of said auger structure.
Claim 6
Dependent Claim
57 words
The invention, as defined in claim 3, wherein: said collar is provided with a set screw and slidably mounted on said body portions so that said set screw may be used to fix said collar on various positions longitudinally of said body to vary the spaced relation of said collar with said cutting end of said drill.
