Pole base providing adjustability for angular axial alignment of the pole

Claim 1

An arrangement for adjusting vertical alignment of a lamp post or the like comprising the combination of: a foundation block having a vertically disposed opening formed therein for receiving an end of said post, said opening being of a larger diameter than the diameter of the portion of the post which is received within said block, a guiding retaining means mounted at the upper end of said block, said guiding retaining means being in the form of an annular wedge block capable of being driven in between the post and the block when the end of the post is received into the block, said annular wedge block having an inner circumferential surface which is generally convex in axial section so that said annular wedge block bears against the post in substantially a line contact, thereby permitting an angular adjustment of the vertical axis of said post relative to said foundation block, and a plurality of jaw means for adjusting the lateral positioning of the lower end of said post to effect a change in vertical alignment of the post, said jaw means being positioned within the opening formed in said foundation block so as to bear against the outside surface of said lower end of the post, and including separate rod means actuatable from the top of said foundation block to vertically adjust the positions of each of said jaw means within the foundation block, said jaw means being guided at their radially outer sides by a guide surface formed in said foundation block on an incline which is directed obliquely downwardly and outwardly to thereby cause a lateral movement of a jaw means when said jaw means is vertically adjusted by its associated rod means.
