Abstract
A gauge for the measurement of the shoulder bone angles of horses with respect to gravity, as an aid in the proper shoeing of the fore feet. The gauge has a gravity reference pointer which swings about a pivot axis so that it points downward under the influence of gravity, and protractor means to indicate the relative angle between the gravity pointer and the horse's shoulder bone angle. The protractor means include an angle scale, a concave locating cup adapted for positioning over the horse's shoulder point, an opposite bone angle pointer integral therewith and optional clamp means for controllably securing the gravity reference pointer with respect to the scale.
Claims12
A gauge for determining the shoulder bone angle of a horse with respect to gravity including:
- a body having integral therewith, a protractor scale about an apex, a bone pointer on a first end thereof, and at least one joint cup on an opposite end thereof;
- a pivot at said apex;
- and
- a pointer pivoted for rotation about said pivot, said pointer having a pointer end and a back end, said pointer end being configured so that said pointer end has a larger moment about said pivot than said back end and having a pointer tip that is positioned adjacent said protractor scale for indicating the relative angle between said body and said pointer.
