Abstract:
The present invention provides a support for frame (10) for a rotary machine (12), particularly a Roots blower, capable of providing support for the machine (12) whilst submerged in a body of liquid. A suspension arm (18) depends downwardly from an upper transom (19) and bears a bracket (32) having mounts (36) by which the machine (12) is mountable to the frame (10) so as to be suspended therefrom.
