View pageUS Patent:
54170931, May 23, 1995
Filed:
Nov 4, 1993
Appl. No.:
8/145564
Inventors:
Martin D. Heiberg - Glendale AZ
International Classification:
F16B 4100
US Classification:
70232
Abstract:
A lock to prevent theft of a marine propeller assembly having a cylindrical shaped housing on which are exteriorly mounted a series of propeller blades, with the open end of the propeller housing being flared outwardly, the assembly further being mountable to a propeller shaft by means of a retaining nut. The propeller lock substantially covers the open end of the propeller assembly and effectively prevents access to the retaining nut and therefore prevents theft of the assembly. The lock has a flat, generally circular shaped face section, with a relatively short wall depending from the perimeter of the face section. The circular shaped face section is formed of two semi-circular sections with the two semi-circular sections being hinged at an edge so they can be closed to form the circular section or opened to form the two semi-circular sections. The depending relatively short wall is angled at an acute inwardly toward the center of the generally circular shaped face section. Means are provided to lock the two semi-circular sections together.
