A drive shaft and coupling adapter assembly for connecting multiple rotary machines to be driven in tandem in a predetermined direction by a single source of power having a rotating power take-off, each rotary machine having a housing with shaft receiving openings in the housing aligned with shaft receiving bearing means, the assembly comprising: (a) common support means having a surface portion upon which said rotary machines are disposed adjacent said power take-off; (b) a coupling adapter having an annular body with a bore extending therethrough, one end of the bore having female screw threads therein and the other end of the bore being shaped to cooperatively engage said power take-off; (c) a drive shaft for each of said rotary machines, each drive shaft being mounted within the shaft receiving opening of each of said rotary machines and having first and second ends, said first ends extending outwardly of said rotary machines, said first ends having male threads capable of cooperatively engaging the female threads of said coupling adapter, said second ends having female threads capable of cooperatively receiving said male threads of an adjacent one of said drive shafts, said drive shafts of the multiple rotary machines being disposed in axial alignment and screwed together and to said coupling adapter, and said male and female threads being so directed as to be tightened when the power take-off is rotated in the predetermined direction; (d) the multiple rotary machines being supported on said common support means with their drive shaft ends mutually screwed together, said common support means including adjustable bracket means for adjustably aligning said surface portion of said support means with respect to the power take-off so that said drive shafts are in axial alignment with the power take-off and with said one end of said coupling adapter screwed on said first end of one of said machine drive shafts nearest the power take-off and having said other end thereof secured to the power take-off, whereby to couple the multiple rotary machines in tandem for rotation therewith.
