The improved housing coupling mechanism includes a first housing such as a motor housing having a first end in abutting relationship to a second housing such as a pump housing. The first housing includes a plurality of slots arranged about the housing perimeter and in a spaced relationship one to another and from the first end of the housing. The second housing includes a plurality of bosses, each boss being configured for coupling an attachment means thereto. Each attachment means includes a fastener (such as a bolt or threaded shaft) and an accompanying plate positionable to be in engagement with one of the slots in the first housing. Each fastener is positionally adjustable in a continuum, thereby providing a force to couple the first housing to the second housing. Coupling is accomplished when each attachment means is adjusted to provide a clamping force between its plate and the slot engaged by the plate. The improved mechanism simplifies and cost-reduces certain components and permits quick and easy assembly and disassembly of the housings.

An improved housing coupling mechanism including: a non-pressurized, thin walled first housing having a non-flared first end and a plurality of perforate slots arranged in a spaced relationship about the perimeter of the first housing, each slot being disposed in a spaced relationship from the first end; a second housing having a rabbet for aligning the first housing with respect to the second housing, such second housing being attached to the first housing in abutting contact to the first end, the second housing including a plurality of bosses integrally formed thereon, each boss being in overlapping relationship to the first end of the first housing, each boss being configured for coupling an attachment means thereto; a plurality of attachment means, each being coupled to a single boss and including a plate extending to engage a slot; each attachment means being positionally adjustable in a continuum for providing a force to couple the first housing to the second housing; the second housing and the first housing being securely coupled to one another when each attachment means is adjusted to provide a clamping force between its plate and the slot engaged thereby; the first housing being securely attached to and aligned on the second housing notwithstanding that the spaces between each slot and the first end of the first housing may be unequal to one another.
