Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
189 words
A motor housing comprised of a pair of identical rigid cupshaped housing frames, each having a relatively closed end and a plurality of walls members extending from the periphery of said closed end, said wall members terminating in a generally continuous rim defining an open end, said rim having a plurality of rabbets formed by flanges having a thickness less than the thickness of said wall members, alternate ones of said flanges extending up from said rim along the inner surface of said wall members and forming a substantially continuous smooth extension thereof to define rabbets formed along the outer surface of said wall members, the remaining flanges extending up from said rim along the outer surface of said wall members and forming a substantially continuous smooth extension thereof to define rabbets formed along the inner surface of said wall members; said housing being formed by the abutment of the rims of said pair of identical cup-shaped housing frames by which a plurality of rabbets joints are formed, said housing having a generally smooth continuous surface extending the length of its wall members between the opposed closed ends thereof.
Claim 2
Dependent Claim
