Abstract
Abstract A vibratory material handler including a material handling surface, a mechanism for vibrating the same and a housing sealing the vibrating mechanism from particulate material in the surrounding environment. The housing includes an apertured wall through which the motor shaft may extend and which is held in substantial abutment with the motor casing. The remainder of the housing holds a weighted member eccentrically mounted on the shaft and shields the same from particulate material while the substantial abutment of the wall at the motor casing effects a substantial seal between the two to preclude entry of particulate material into the motor itself.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
175 words
A vibratory handling apparatus comprising: means defining a material handling surface adapted to perform work on material when vibrated; and means secured to said surface for vibrating the same, said vibrating means defining a box-like frame including a pair of spaced, generally parallel plate-like frame members, means for securing said plate-like frame members to said surface, a motor having a sealed casing with rotary output shafts extending from both ends thereof, said motor casing having opposed, generally planar ends sandwiched between said plates and in abutment therewith, said plates including aligned apertures through which said output shafts pass, a pair of weights, each eccentrically secured to a corresponding one of said output shafts, the ends of said casing being in substantial sealing engagement with corresponding ones of said plates, and means including said plates defining a closed housing for each of said weights, said housings being of sufficient size to accommodate the rotation of the respective weight therein by said motor, at least a portion of said frame being open and exposing said motor casing.
