Abstract
Abstract A device for expanding elastic rings so that they can be transferred to an appendage of an animal for ultimate removal of the appendage. The device consists of an originally cylindrical tube which is adapted to fit over the appendage. The forward portion of the tube is cut away to define a tapered front point and side walls having upwardly and rearwardly inclined upwardly concave top edges leading to the cylindrical rear end portion of the tube to facilitate the mounting of the elastic rings on the rear end of the tube, from which they can be rolled off to embrace the appendage to be removed.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
150 words
An animal docking tool comprising a one-piece, hollow, rigid, cylindrical tube open at both ends having a short rear end portion and a tapered forward end portion of substantial length integral with and merging with said ring portion, said rear end portion having cross-sections which are complete circles for receiving an expanded elastic docking ring, said tapered forward portion being formed by omission of part of the wall of said tube so that successive cross-sections in the rearward direction are gradually increasing segments of a circle and the wall of the tube presents upper edges which are inclined upwardly and rearwardly from a forward tip toward said rear end ring portion for receiving non-expanded elastic docking rings for movement therealong to expand the same, said upper edges defining curves which are upwardly concave for the major portions of their lengths and becoming upwardly convex adjacent said rear end ring portion.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
28 words
The docking tool of claim 1, wherein said tip of the tapered forward end portion is rounded, and said upper edges of the forward portion are smoothly curved.
