Abstract

Abstract A bell housing, for the assembly together of electric motors and driven items, e.g., pumps, comprises a tubular body with a first co-axial flange at one end for mounting a motor, and a second coaxial flange at the other end for mounting a driven item, the first flange including a plurality of sets of holes, the holes of each set being arranged at the same radius from the common central axis of the flange and the body, the radius of each set being different from the radius of each other set, whereby the same bell housing may be used for mounting motors having flanges of at least two different sizes.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 152 words
A bell housing, for securing between an electric motor and a structure, comprising an integrally formed one-piece body which includes: i. an intermediate tubular portion having first and second ends ii. a first coaxial mounting flange portion extending from said first end of said intermediate portion and including a plurality of sets of holes, the holes of each set being arranged at the same radius from the common central axis of the first coaxial mounting flange portion and the intermediate tubular portion, the radius of each set of holes being different from the radius of each other set of holes, thereby to permit the securing to said first coaxial mounting flange portion of electric motors having mounting holes of selectively different corresponding radius iii. a second coaxial mounting flange portion extending from said second end of said intermediate portion and including a set of holes for mounting said flange to a structure.
Claim 2
Dependent Claim 152 words
A bell housing, for securing between an electric motor and a structure, comprising an integrally formed one-piece body which includes: i. an intermediate tubular portion having first and second ends ii. a first coaxial mounting flange portion extending from said first end of said intermediate portion and including a plurality of sets of holes, the holes of each set being arranged at the same radius from the common central axis of the first coaxial mounting flange portion and the intermediate tubular portion, the radius of each set of holes being different from the radius of each other set of holes, thereby to permit the securing to said first coaxial mounting flange portion of electric motors having mounting holes of selectively different corresponding radius iii. a second coaxial mounting flange portion extending from said second end of said intermediate portion and including a set of holes for mounting said flange to a structure.
Claim 3
Dependent Claim 152 words
A bell housing, for securing between an electric motor and a structure, comprising an integrally formed one-piece body which includes: i. an intermediate tubular portion having first and second ends ii. a first coaxial mounting flange portion extending from said first end of said intermediate portion and including a plurality of sets of holes, the holes of each set being arranged at the same radius from the common central axis of the first coaxial mounting flange portion and the intermediate tubular portion, the radius of each set of holes being different from the radius of each other set of holes, thereby to permit the securing to said first coaxial mounting flange portion of electric motors having mounting holes of selectively different corresponding radius iii. a second coaxial mounting flange portion extending from said second end of said intermediate portion and including a set of holes for mounting said flange to a structure.
Claim 4
Dependent Claim 152 words
A bell housing, for securing between an electric motor and a structure, comprising an integrally formed one-piece body which includes: i. an intermediate tubular portion having first and second ends ii. a first coaxial mounting flange portion extending from said first end of said intermediate portion and including a plurality of sets of holes, the holes of each set being arranged at the same radius from the common central axis of the first coaxial mounting flange portion and the intermediate tubular portion, the radius of each set of holes being different from the radius of each other set of holes, thereby to permit the securing to said first coaxial mounting flange portion of electric motors having mounting holes of selectively different corresponding radius iii. a second coaxial mounting flange portion extending from said second end of said intermediate portion and including a set of holes for mounting said flange to a structure.
Claim 5
Dependent Claim 42 words
A bell housing, as claimed in claim 1, wherein said first coaxial mounting flange portion of said body has a major face remote from said intermediate portion of said body, said major face including coaxial axially-extending arcuate recesses to receive packing material.
