Abstract: A low profile platform scale having a rigid rectangular platform and a base assembly, supporting the platform, adapted to rest on an underlying foundation and having four independent corner pads, each with beam load cells mounted in cantilever fashion on the corner pads, with the load cell elements coupled to the platform in an arrangement where the load on the platform is transmitted to the load cell elements by means of a tension member. The tension member is connected by ball and socket means to both the platform and the load cell element. The corner pads are connected to each other by slightly flexible, inelastic rods arranged beneath and adjacent borders of the platform in a rectangular array, and fastened to adjacent corner pads for fixing the spacing between them. The underlying corner pads operate independently and accommodate locally irregular surfaces causing any one of the corner pads to be slightly tilted without affecting the accuracy of response of the load cell.

Abstract: A low-profile platform scale has a horizontal base, a lower primary U-shaped lever, an upper secondary U-shaped lever, a horizontal platform, and load cell means mounted on the base. The base has a unitary structure including a front pair and a rear pair of modified vertical angle irons connected to the ends of a horizontal shallow rectangular tubing and supporting short inverted channel irons each with one leg shorter than the other, to provide a pair of spaced upstanding portions of the base at the central part of the front and rear margins of the base with a portion of the short flanges and a portion of the long flanges of the pair of channel irons providing mounting means at upper and lower elevations as vertical flat surfaces facing the ends of the scale. These flat surfaces are at two transverse vertical planes.
