Portable low profile mechanical scales

A portable low profile mechanical scale comprising a carriage having a pair of spaced apart side frame members, each having wheel means at one end and ground support means adjacent the other end, spacer means extending between said side frame members substantially at ground level holding said side frame members in spaced apart parallel relation, wheeled lift means at said other ends of the side frame member for lifting said other ends to raise the ground support means, a pair of torsion bars above said side members at two different parallel levels, one adjacent each side frame and supported theron by triangular link means fixed to the torsion bars at one end and supported on the side members at the other, weigh bed means movable vertically between said side frame members and pivoted to said link members between the torsion bar and support on the side frame members, lever means on each torsion bar adjacent said wheel lift means extending transversely toward each other, one above the other, link means connecting said lever means midway between said side frame members and connector means on the end of the lever above the other for connection to a weight indicating mechanism.
