Total Claims: 9
Claim 1
Independent Claim
219 words
A gear case housing for encasing a plurality of moving parts included in a drive train, the combination comprising: a pair of substantially identical sections having corresponding and mating edges for joining in abutting engagement to constitute an enclosure about said moving parts and a selected one of said sections is provided with a double thickness of fiberglass at its bottom end as compared to the thickness of its end and sides; guide means cooperatively carried by said opposing section edges for aligning and retaining said section together to define said enclosure which includes a tongue-in-groove construction cooperatively disposed between selected opposite and opposing section edges, said guide and supporting means including strips of steel carried along a selected one of said section edges and projecting beyond said selected edge to engage with said other edge; each of said sections preformed with selected cut-out portions along said edges so as to align together to define passageways leading into the interior of said enclosure, said sections being composed of fiberglas material; and sealing and bearing means carried in each of said cut-outs to provide a continuous engagement with portions of said moving parts extending through said passageways, said sealing and bearing means comprising an inner flange composed of steel and another flange composed of fiberglas integral with said respective section.
