ABSTRACT:
RELATED APPLICATIONS
The present invention was first described in Disclosure Document Number 459,003 filed on Jun. 24, 1999. There are no previously filed, nor currently any co-pending applications, anywhere in the world.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to extendible tree-pruning devices and, more particularly, to an adjustable aerosol can holder attachment for attachment to a conventional tree pruner.
2. Description of the Related Art
Within the related art, numerous patents exist for tree-pruning pole devices, and power saw pruning devices. These include U.S. Pat. No. 5,241,752 issued in the name of Lutzke et al., U.S. Pat. No. 5,084,975 issued in the name of Melter, U.S. Pat. No. 4,096,630 issued in the name of Honick, U.S. Pat. No. 4,033,036 issued in the name of Morris, and U.S. Pat. No. 3,835,535 issued in the name of Robinson et al.
U.S. Pat. No. 5,787,536 issued in the name of Pate describes a remote saw system comprising a radio transmitter, receiver, and a servomechanism.
U.S. Pat. No. 5,756,542 issued in the name of Kojima et al. discloses an ointment-like preparation of a tree and removal of parts of the tree.
U.S. Pat. No. 5,143,131 issued in the name of Seigneur describes a selectable fluid spraying chain saw bar system.
U.S. Pat. No. 4,566,188 issued in the name of Wilson discloses a power saw pruning device including an elongated pole handle.
U.S. Pat. No. 3,949,440 issued in the name of Guerra describes a combined tree saw, pruner, and paint sprayer. However, the Guerra invention has the paint sprayer holder and spray mechanism integrally built into the tree pruner and has no application to existing tree pruners. Accordingly, there is a need for an aftermarket aerosol sealant attachment kit for a conventional tree pruner.
While tree-pruning devices are incorporated into this invention in combination, other elements are different enough as to make the combination distinguished over the related art.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an improved aftermarket aerosol attachment kit for conventional tree pruners.
It is a feature of the present invention to seal pruned ends of trees against bug infestation and rot without the use of a ladder.
It is another feature of the present invention to provide an actuation lever which attaches to a lever arm and is easily actuated by a pull rope.
Briefly described according to the preferred embodiment of the present invention, an adjustable aerosol can holder attachment for a tree pruner is disclosed comprising a receiving sleeve demountably and adjacently positioned midway along the lateral external surface of a cutting head of a conventional tree pruner. The receiving sleeve is made from a shear resistant fabric material of high-tensile strength formed into an elongated cylindrical configuration wherein an upper and lower buckle clamp are attached to its outer surface for securing an aerosol can within the interior of the receiving sleeve. The upper and lower buckle clamp adjustably accommodate aerosol sealants of various sizes. A wedge-shaped plate having a slot formed in its front edge clamps to the cutting head of the tree pruner. An L-shaped actuation lever is pivotally connected to the outer surface of the wedge-shaped plate via a pivot pin for depressing a plunger which presses the spray head of the aerosol can whenever the lever arm of the tree pruner is pulled down via a rope and pulley system on the tree pruner.
An advantage of the present invention is that it can be easily attached to a conventional tree pruner.
Another advantage of the present invention is that it alleviates the need for ladders and can be used at any angle.
