Device for indicating slope of green on golf course

Claim 1

A portable device for measuring the slope of a sloped surface comprising, in combination: a. a level mount structure having a horizontally disposed elongated central body portion providing a laterally extending upper surface and rotatable wheel means mounted therein enabling said upper surface to be moved over and in immediate proximity to said sloped surface; b. an elongated tubular handle having one end centrally secured to and extending upwardly from said body portion and being of length sufficient to enable a user to hold an opposite unsecured end thereof and move said level mount structure on said wheel means in immediate proximity to said sloped surface and while walking in an upright position over said sloped surface; c. an elongated bubble type level secured to said upper sureface of said level mount structure with the axis thereof oriented generally lengthwise of said body portion and perpendicular to the axis of said handle and having a bubble normally centered along a line coinciding with the axis of said handle when said level mount structure is supporting said bubble level in a substantially level position; and d. indicia marks inscribed on said level mount upper surface proximate said bubble level enabling the relative position of said bubble when said mount structure is tilted to be determined in reference to the slope of the portion of said sloped surface immediately below said bubble level. eA device as claimed in claim 1 wherein said body portion provides vertical end surfaces, said wheel means comprises a pair of wheels with one wheel being mounted adjacent each said end surrace, said upper surface and said bubble level are of corresponding downward curvature and said bubble level is recessed in said uppeR surface.
