Abstract: A housing for dispensing material, particularly granular material, has a ramp shaped bottom surface inclined towards a front discharge chute. The chute is retained in a compartment which is integrally formed together with the housing. The housing is formed from two substantially identical half sections which are removably joined together, each of the housing half sections including a half section for the retaining compartment for the chute. In its assembled position, the chute has a plate-like gate element, pivotable between closed and opened positions, through actuation of an armature mechanically linked to the gate. The housing sections can be formed from known injection molding processes.

Abstract: A locking system for supporting legs removably mounted to a tray, table or other structure to be supported includes cooperating engagement elements for removably connecting a supporting element, such as a pole or leg, to a clamp. The connected pole and clamp are removably retained, as a unit, in a retaining element extending from the structure to be supported. A stop element is provided on the clamp, the retaining element, or both, so that the clamp and the pole are retained as a single unit in a desired position within the retaining element when the locking system is assembled. The system may be readily assembled and disassembled into its individual components without employing any special tools.
