Spring scale with protective cover

Claim 1

A spring scale comprising a boxlike casing having spaced parallel flat sidewalls, a rear wall, a horizontal top wall, and a curved front wall having a longitudinal slot therein with index numbers thereon adjacent said slot for reading weights; a platform for supporting articles to be weighed movably disposed above the top wall of said casing; and axially movable vertical shank supporting said platform and extending downwardly into the the interior of the casing; linkage means pivotally attached to said sidewalls and to said shank for movably supporting the shank; adjustable spring means connected between said top wall and said shank for yieldably supporting the platform; a pointer extending from said linkage means outwardly through said slot and movable along said front wall for indicating weights when the platform is depressed; and a cover for said casing comprising a four sided structure formed with mutually perpendicular integral top, side and end walls, said sidewalls of the cover being formed with extensions pivotally joined to the sidewalls of said casing for pivoting the cover over the casing, stop means on the casing for limiting pivotal movement of the cover over the casing, the interior spacing of the sidewalls of the cover being slightly greater than the spacing of the sidewalls of the casing so that the sidewalls of the cover can be juxtaposed to the sidewalls of the casing for frictional engagement therewith, while the top and end walls of the cover overlay anD protect the top and front walls respectively of the casing, and while the platform bears against the top wall of the cover to hold the same in place on the casing when the cover is pivoted over the casing.
