Abstract

An apparatus for a wheeled vehicle for slashing pine trees to enhance the production by natural means of terpenoid materials, and comprising a tree slashing device pivotally mounted at the end of an arm extending from the vehicle, and irritant applicator also carried on said tree slashing device for applying an irritant material to the freshly slashed wound in the stem of the tree.

Claims

1. A tree slashing and treating apparatus carried by a wheeled vehicle and adapted to move continuously between parallel rows of trees and comprising a pair of oppositely laterally extending telescoping arms secured at their respective proximal extremities to said vehicle, means coacting with each of said telescoping arms for extending and retracting said arms, each of said arms having pivotally secured at its distal extremity chain saw tree slashing means for slashing a tree to remove a strip of bark and exposed an under bark portion of the tree, said chain saw means including an endless saw chain and spaced sprockets mounted respectively on vertical shafts and disposed for movement of the chain around said sprockets in a horizontal plane, means coacting between each of said arms and the respective chain saw means pivotally mounted thereon for restoring said chain saw means from a tree-deflected position to a normal tree-intercepting position after said vehicle has passed a deflecting tree, actuator means and liquid delivery means, respectively carried by each said chain saw tree slashing means said actuator means being vertically displaced from said tree slashing means and adapted to contact the trunk of the tree for causing a liquid treating agent to be applied through said liquid delivery means to said exposed under bark portion.

2. A tree slashing and treating apparatus as defined in claim 1 wherein said chain is carried in a chain guide bar.

3. A tree slashing and treating apparatus as defined in claim 1 wherein said tree slashing means includes means for driving said movable chain.

4. A tree slashing and treating apparatus as defined in claim 3 wherein said driving means is a hydraulic motor.

5. A tree slashing and treating apparatus as defined in claim 1 wherein said liquid delivery means includes a supply line, a treating agent supply, and a valve in said supply line to control the movement of treating agent therethrough, and means responsive to contact with a tree for actuating said valve from a normally closed position to an open position.

6. A tree slashing and treating apparatus as defined in claim 5 wherein the tree contacting means is a wheel fixedly mounted on a cam, a cam follower coacting between said cam and said valve, said cam being freely rotatable about the outermost sprocket shaft, and yieldable means for returning said cam to position said wheel in a tree trunk intercepting position.
