ABSTRACT:
A measuring scale casing or housing and spar therefor. The spar comprises integral top and back walls. The back wall is provided proximate its lower end, with a lip extending in the same direction as the top wall. The internal surface of the lip has a groove.
The casing is provided with top, back and front walls and is provided with a downward protrusion proximate the bottom of the back wall. The protrusion is sized to fit within the groove of the lip of the spar in dovetail fashion when the exterior surface of the top wall of the casing is proximate the internal surface of the top wall of the spar and when the exterior surface of the back wall of the casing is flush against the internal surface of the back wall of the spar.
The top wall of the casing is provided with a V-shaped groove and the spar is provided with set screws in the top wall. The set screws can be screwed into the top wall to contact the surface of the side of the V-shaped groove which is closest to the back wall of the bracket to force the protrusion of the casing into the groove in the lip and to force the exterior surface of the back wall of the casing against the internal surface of the back wall of the spar.
