Navigation light for boats

Claim 1

A navigation light for boats comprising a post, illuminating means carried by said post, a mounting bracket adapted to be mounted on a boat and having an opening of tapered cross-section defined by tapered side walls extending therethrough, said mounting bracket having an upstanding neck through which the opening in said bracket extends, a bushing mounted in the opening in said bracket and slidable therein to a limited extent in one direction parallel to the longitudinal axis of the opening in said bracket, said bushing having an outer surface, a part of said outer surface being tapered to conform generally to said tapered side walls and engaging said tapered side walls, said bushing having a threaded neck, said threaded neck projecting beyond said neck pf saod bracket, said bushing also having an opening of cross-section complementary to the cross-section of said post, and said opening extending through said bushing and through said threaded neck thereof in the same general direction as the opening in said bracket, said post being mounted in the opening in said bushing, said bushing having a slot therein extending from said outer surface into the opening in said bushing anD extending from one end of said bushing to the other end thereof, and a cap member having an opening therethrough which said post extends, said cap member being threadably engageable with said threaded neck of said bushing and adapted to draw said part of said outer surface of said bushing into tight engagement with said tapered side walls defining the opening in said bracket by moving said bushing in said one direction, whereby the width of at least a part of said slot is decreased and said bushing is drawn into tight gripping engagement with said post, said cap member having a skirt portion extending over said neck of said bracket and spaced apart from said neck of said bracket, a first electrical element, said first electrical element being positioned in the lower end of said post comprising openings therein and spaced contacts in said openings, a second electrical element having spaced prongs, means for mounting and circumferentially locating said second electrical element on said bracket with said second electrical element substantially closing the lower end of said opening in said bushing and with said prongs extending upwardly into the opening in said bushing, the prongs on said second electrical element extending into said openings in said first electrical elements to provide an electrical connection therebetween when said post is supported on said base, and electric lead means extending between said first electrical element and said illuminating means for completing a circuit thereto.
