ABSTRACT:
A weighing apparatus is provided with a wind shielding arrangement for protectively enclosing a load-receiving scale member. A plurality of symmetrical curvilinear concave transparent shell-like wind shield sections of unequal diameters of generation are concentrically mounted on the scale housing above the load-receiving pan for relative rotational movement about a common axis between a closed protective condition, and an open condition affording access to the scale pan. In one embodiment, a pair of shield sections have generally coplanar edge portions mounted in a pair of concentric circular grooves, respectively, contained in a support on the upper surface of the housing adjacent the load receiving member. The inner shield section is retained in its associated groove by a resilient annular retainer ring that extends radially outwardly above a radially inwardly extending lip portion on the lower edge of the inner shield section.
