3. The apparatus according to claim 1 , wherein the angle bracket has at least one elongated second slot, and wherein a second fastener is disposed in the second slot in connection with the mounting plate to permit angular adjustment of the mounting plate in a second direction.
4. The apparatus according to claim 2 , wherein the angle bracket has at least one elongated second slot therein, and wherein a second fastener is disposed in the second slot in connection with the mounting plate to permit angular adjustment of the mounting plate in a second direction.
5. The apparatus according to claim 2 , wherein the first fastener is a screw or bolt.
6. The apparatus according to claim 3 , wherein the second fastener is a screw or bolt.
7. An apparatus for adjustably supporting a fan motor on a cooling tower, comprising:
supporting means slideably mounted to the cooling tower;
pivoting mounting means pivotally mounted to the supporting means; and
pivoting connecting means pivotally mounted to the supporting means, wherein the pivoting mounting means has a slideable connection to the pivoting connecting means, and wherein the mounting means, the connecting means, and the supporting means generally form a triangle.
8. The apparatus according of claim 7 , wherein the supporting means has at least one elongated first slot, and a first fastener is disposed through the first slot in connection with the cooling tower, to provide linear adjustment in a first direction.
9. The apparatus according to claim 7 , wherein the connecting means has at least one elongated second slot, and wherein a second fastener is disposed in the second slot in connection with the mounting means to permit angular adjustment of the mounting means in a second direction.
10. The apparatus according to claim 8 , wherein the connecting means has at least one elongated slot therein, and wherein a second fastener is disposed in the second slot in connection with the mounting means to permit angular adjustment of the mounting means in a second direction.
11. The apparatus according to claim 8 , wherein the first fastener is a screw or bolt.
12. The apparatus according to claim 9 , wherein the second fastener is a screw or bolt.
13. A method for adjustably supporting a fan motor on a cooling tower, comprising;
linearly adjusting a bracket slideably mounted to the cooling tower;
adjusting a pivoting mounting plate pivotally mounted to the bracket; and
adjusting a pivoting angle bracket pivotally mounted to the bracket, wherein the mounting plate has a slideable connection to the angle bracket, and wherein the bracket, the mounting plate, and the angle bracket generally form a triangle.
14. The method according of claim 13 , wherein the angle bracket has at least one elongated first slot, and a fastener is disposed through the first slot in connection with the cooling tower, to provide linear adjustment in a first direction.
15. The method according to claim 13 , wherein the angle bracket has at least one elongated second slot, and wherein a second fastener is disposed in the second slot in connection with the mounting plate to permit angular adjustment of the mounting plate in a second direction.
16. The method according to claim 14 , wherein the angle bracket has at least one elongated second slot therein, and wherein a second fastener is disposed in the second slot in connection with the mounting plate to permit angular adjustment of the mounting plate in a second direction.
17. The method according to claim 14 , wherein the first fastener is a screw or bolt.
18. The method according to claim 15 , wherein the second fastener is a screw or bolt.
19. An apparatus for adjustably supporting a fan motor on a cooling tower, comprising:
