US 4,649,665 A · Tree branch spreader

Abstract

A tree branch spreader is used for structural training and orienting the position of growing branches to shape the tree for its intended purpose, such as maximizing the fruit yield for orchardists. The branch spreader is preferably trapezoidal in shape and comprises an elongated spacer portion and opposite ends, each of which further comprising a plurality of intercommunicating notches within which the branches are protectively and removably secured during growth. In the preferred embodiment, smaller primary notches at each end of the spreader are longitudinally positioned at an interiormost location along the spreader, opening into and communicating with a larger secondary notch which in turn opens to communicate with a largest tertiary notch at the exteriormost location of the opposite ends of the spreader. The primary notches each comprise a transversely positioned resting surface and oppositely spaced apart sidewalls displaced perpendiculary therefrom. Adjacent larger secondary and tertiary notches comprise a pair of resting surfaces, extending perpendicularly from the outer edges of the adjacent smaller notch and communicating with a pair of sidewalls, each depending perpendicularly from its respective resting surface. The resting surfaces of the opposite ends are positioned in coplanar alignment, forming an acute angle with respect to the top surface of the spreader. Additionally, the resting surfaces are curved inwardly in a concave manner.

A tree branch spreader for structural training and supportive orientation of growing limbs and branches, comprising an elongated spacer portion having a top surface and bottom surface and further having opposite ends which each further comprise a plurality of notches including a first primary notch at a relative interior position along the spacer portion, opening into and communicating with at least one wider secondary notch, the notches each further comprising at least one growing surface, curved inwardly in a concave manner with respect to the opposite ends of the spreader, and oppositely spaced apart sidewalls to provide protective surfaces of travel for the branches in an upward and outward direction.

A tree branch spreader for structural training and supportive orientation of growing limbs and branches comprising an elongated spacer portion, trapezoidal in shape and having a top surface and bottom surface wherein the top surface is greater in length than the bottom surface and having opposite ends which each further comprise a plurality of integrally formed intercommunicating notches, successively increasing in width to define partial openings to receive the branches or limbs of varying diameter, and in respect to the growth of the branches, to provide a means to protectively guide the branches, and a means to establish a path of travel for branches, said notches further comprising:

(a) a first primary notch at a relative interior position along the spacer portion from its respective opposite end, the primary notch further comprising:
a primary resting surface, curved inwardly in a concave manner with respect to the opposite ends of the spreader and transversely positioned to the longitudinal axis of the spreader;
and opposite spaced apart side walls, substantially parallel to each other and angularly displaced from the primary resting surface toward their respective opposite end, and;
(b) at least one larger secondary notch extending from and openly communicating with the primary notch and positioned at a relative exterior position along the spacer portion and openly communicating with its respective opposite end of the spreader, each of the secondary notches further comprising at least one secondary resting surface, curved inwardly in a concave manner with respect to the opposite ends of the spreader and angularly displaced outwardly from the sidewalls of the primary notch, and oppositely spaced apart sidewalls, in substantial parallel alignment and angularly depending from their respective secondary resting surface and depending toward a respective opposite end, said resting surfaces of each larger secondary notch depending from and forming a continuous edge with the smaller adjacent relatively interior positioned notch, said ends of a tree branch spreader terminating in oppositely spaced apart resting surfaces, coplaner in alignment and parallel with the other resting surfaces, further depending from the sidewalls of the adjacent smaller relatively interior located notch.
