Level indicating golf putter
First Claim
1. A golf club putter head comprising:
- a body member having and definingan elongate flat planar face,a sole that lies in a curved surface everywhere perpendicular to the plane of the face, andtwo spaced-parallel equal-length frustaconical projections each having a central axis and extending perpendicularly oppositely to the planar face at maximum separation along the elongation of the face;
a spirit level affixed to the body member along an imaginary first axis that is spaced-parallel to both an imaginary line between apexes of the frustrums of the two frustaconical projections and to the planar face, the spirit label extending for substantially the entire length of the body member;
an attachment means for releasibly affixing the spirit level to the body member; and
a hostel affixed to the body member in a position substantially midway between the maximally-separated spaced-parallel frustaconical projections;
wherein at such times as the body member is tilted so that only the apexes of the frustrums of its two frustaconical projections contact a surface of the earth, then the spirit level indicates the inclination of the imaginary line between these apexes of the two frustrums, and thus the slope of the earth'"'"'s surface along this imaginary line.

Abstract
A golf club putter head affixing an elongate spirit level may be tilted relative to earth and rested on its two frustaconical projections so as to accurately measure earth inclination nonetheless that, inter alia, the sole of the putter head is curved, and thus unsuitable to serve to reference the putter head to the earth'"'"'s surface. The two frustaconical projections are preferably spaced parallel, equal length, maximally separated and axially weighted. The spirit level is preferably both removably affixed--permitting use of the putter in regulation play--and of maximum elongate extent. A preferably offset hostel is affixed in a position preferably substantially midway between maximally-separated spaced-parallel frustaconical projections.
