Abstract
Abstract Apparatus and method for vibrating a specimen in multiple directions. Exciters for vibration in the X and Y orthogonal directions are coupled to shafts extending through orifices in the hollow vibrator to X and Y control plates on the inside of the vibrator in contact with the interior walls thereof to move the vibrator in X and Y directions. A Z-axis exciter is coupled to the base of the vibrator for moving it in the Z-axis direction. The orifices for the X and Y-axis exciter shafts are sufficiently large to allow Z-axis movement of the vibrator without affecting the motions of the X and Y shafts.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
245 words
An apparatus for vibrating specimens simultaneously in multiple directions, said apparatus comprising: a. a hollow vibration shaft for supporting a vibration table to which specimens may be fixed; b. a first pair of parallel, spaced plates connected to each other and located on the interior of and in contact with said vibration shaft; c. a second pair of parallel, spaced plates connected to each other and located on the interior of and in contact with said vibration shaft in a direction perpendicular to the direction faced by said first parallel spaced plates, d. a first pair of connecting shafts inserted through first openings formed in said vibration shaft with a clearance of at least the width of vibration, said first pair of shafts being respectively connected to said first pair of parallel spaced plates for movement thereof; e. a second pair of connecting shafts inserted through second openings formed in said vibration shaft with a clearance of at least the width of vibration; said second pair of shafts being connected to said second pair of parallel spaced plates for movement thereof, f. a first exciter coupled to at least one of the first pair of connecting shafts for applying a vibration through said first connecting shaft in a first direction; and g. a second exciter coupled to at least one of the second pair of connecting shafts for applying a vibration through said second connecting shaft in a second direction perpendicular to said first direction.
Claim 2
Independent Claim
245 words
An apparatus for vibrating specimens simultaneously in multiple directions, said apparatus comprising: a. a hollow vibration shaft for supporting a vibration table to which specimens may be fixed; b. a first pair of parallel, spaced plates connected to each other and located on the interior of and in contact with said vibration shaft; c. a second pair of parallel, spaced plates connected to each other and located on the interior of and in contact with said vibration shaft in a direction perpendicular to the direction faced by said first parallel spaced plates, d. a first pair of connecting shafts inserted through first openings formed in said vibration shaft with a clearance of at least the width of vibration, said first pair of shafts being respectively connected to said first pair of parallel spaced plates for movement thereof; e. a second pair of connecting shafts inserted through second openings formed in said vibration shaft with a clearance of at least the width of vibration; said second pair of shafts being connected to said second pair of parallel spaced plates for movement thereof, f. a first exciter coupled to at least one of the first pair of connecting shafts for applying a vibration through said first connecting shaft in a first direction; and g. a second exciter coupled to at least one of the second pair of connecting shafts for applying a vibration through said second connecting shaft in a second direction perpendicular to said first direction.
