Abstract

Abstract Method and apparatus for treating trees includes at least one cutting element having a fluid passageway therethrough, facilities for positioning the cutting element around the periphery of a tree, and facilities for driving said cutting element through the bark of a tree to expose the sapwood therein and for ejecting a predetermined quantity of fluid through the passageway in the cutting element onto the sapwood of a tree. In addition, the invention includes a method for the chemical treatment of trees.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 78 words
Apparatus for injecting liquid into a tree comprising: a plurality of cutting elements having fluid passageways therethrough; means, in communication with said passageways, for supplying a liquid; means for positioning said cutting elements around the periphery of a tree; means for driving certain of said cutting elements through the bark of the tree substantially to expose the sapwood simultaneously thereof and for ejecting a predetermined quantity of liquid through said passageways in said cutting element onto the sapwood.
Claim 2
Dependent Claim 78 words
Apparatus for injecting liquid into a tree comprising: a plurality of cutting elements having fluid passageways therethrough; means, in communication with said passageways, for supplying a liquid; means for positioning said cutting elements around the periphery of a tree; means for driving certain of said cutting elements through the bark of the tree substantially to expose the sapwood simultaneously thereof and for ejecting a predetermined quantity of liquid through said passageways in said cutting element onto the sapwood.
Claim 3
Dependent Claim 25 words
The apparatus of claim 1, wherein said mans for positioning said cutting element includes at least one member which engages the trunk of said tree.
Claim 4
Dependent Claim 34 words
The apparatus of claim 2, wherein said engaging member is a clamp, pivotally mounted on a mounting plate, and actuated by means for forcing said clamp against said tree to position said cutting element.
Claim 5
Dependent Claim 49 words
The apparatus of claim 3 wherein means for driving said cutting elements and ejecting a predetermined amount of liquid includes means for withdrawing said cutting elements and wherein said cutting elements are mounted on a plate which extends around at least a portion of the trunk of said tree.
Claim 6
Dependent Claim 49 words
The apparatus of claim 4, wherein said plate is substantially semi-circular, having a semi-circular opening therein for positioning around the trunk of said tree, having a plurality of said cutting elements mounted thereon with said blade of each of said cutting elements disposed toward the trunk of said tree.
Claim 7
Dependent Claim 49 words
The apparatus of claim 5 including: mobile means for moving said apparatus from tree to tree, wherein said mobile means includes a vehicle having rotatably attached thereto an hydraulic boom for adjustment of the position of said cutting elements; and means for adjusting the force of said driving means.
Claim 8
Dependent Claim 26 words
The apparatus of claim 1 wherein means for driving said cutting elements and ejecting a predetermined quantity of liquid includes means for withdrawing said cutting element.
Claim 9
Dependent Claim 29 words
The apparatus of claim 1 wherein a plurality of cutting elements is mounted on a plate which extends around at least a portion of the trunk of said tree.
Claim 10
Dependent Claim 18 words
The apparatus of claim 1, including means for alternately activating adjacent cutting elements to form a continuous frill.
Claim 11
Dependent Claim 37 words
The apparatus of claim 1, including mobile means for moving said apparatus from tree to tree and for adjusting the position of said apparatus in relation to the size and position of the trunk of said trees.
Claim 12
Dependent Claim 28 words
The apparatus of claim 10 wherein said mobile means includes a vehicle having rotatably attached thereto an hydraulic boom for adjustment of the position of said cutting elements.
Claim 13
Dependent Claim 21 words
The apparatus of claim 1 wherein said driving and ejecting means includes means for adjusting the force of said driving means.
Claim 14
Independent Claim 113 words
A method of applying a treating chemical to a growing tree comprising: positioning an apparatus having a plurality of cutting elements around a tree, each of said cutting elements having a fluid passageway therethrough, wherein said apparatus includes means for positioning said cutting elements around said tree, means for driving certain of said cutting elements through the bark of said tree substantially to expose the sapwood simultaneously thereof and for ejecting a predetermined quantity of liquid through said passageways in each of said cutting elements onto the sapwood; opening frills along the surface of said tree with said cutting elements; and substantially simultaneously injecting said liquid onto the upper surface of said frills.
Claim 15
Independent Claim 113 words
A method of applying a treating chemical to a growing tree comprising: positioning an apparatus having a plurality of cutting elements around a tree, each of said cutting elements having a fluid passageway therethrough, wherein said apparatus includes means for positioning said cutting elements around said tree, means for driving certain of said cutting elements through the bark of said tree substantially to expose the sapwood simultaneously thereof and for ejecting a predetermined quantity of liquid through said passageways in each of said cutting elements onto the sapwood; opening frills along the surface of said tree with said cutting elements; and substantially simultaneously injecting said liquid onto the upper surface of said frills.
Claim 16
Dependent Claim 17 words
The method of claim 13 wherein the injected liquid is an aqueous solution of substituted bipyridylium salt.
Claim 17
Dependent Claim 35 words
The method of claim 13 wherein the frills made along the surface of the tree are made around the periphery of said tree, in a plane substantially normal to the vertical axis of said tree.
Claim 18
Dependent Claim 23 words
The method of claim 15 wherein the circumferential frills made along the surface of the tree constitute approximately 50% of the circumference thereof.
