Abstract
Abstract An improved housing for fractional horsepower AC motor in which the housing is made of two housing halves which can be fitted together, each of the housing halves having tabs bent perpendicular to the plane thereof with the tabs so arranged and designed that their latteral edges are pressed against each other when the housing halves are fitted together thereby making it possible for the housing to be compressed to the desired height during the fitting operation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
115 words
In a housing for a fractional horsepower A-C motor of the type comprising two housing halves of the same diameter which are fitted together with each housing half containing poles, forming a pole system for the A-C motor, an improved form of construction, comprising a plurality of tabs on each of the housing halves bent perpendicular to the plane of the housing halves with at least one tabe of each housing half assuming a predetermined position relative to the pole system of the repsective housing half and wherein when the housing halves are fitted together, the lateral edges of the tabs of one are pressed against the tabs of the other at least in part.
Claim 2
Dependent Claim
115 words
In a housing for a fractional horsepower A-C motor of the type comprising two housing halves of the same diameter which are fitted together with each housing half containing poles, forming a pole system for the A-C motor, an improved form of construction, comprising a plurality of tabs on each of the housing halves bent perpendicular to the plane of the housing halves with at least one tabe of each housing half assuming a predetermined position relative to the pole system of the repsective housing half and wherein when the housing halves are fitted together, the lateral edges of the tabs of one are pressed against the tabs of the other at least in part.
Claim 3
Dependent Claim
19 words
A housing according to claim 1 wherein the length of the tabs is shorter than the axial housing height.
Claim 4
Dependent Claim
13 words
A housing according to claim 1 wherein the two housing halves are identical.
Claim 5
Dependent Claim
120 words
In a housing for a fractional horsepower A-C motor of the type comprising two housing halves of the same diameter which are fitted together with each housing half containing poles forming a pole system for the A-C motor, an improved form of construction, comprising a plurality of tabs on each of the housing halves bent perpendicular to the plane of the housing halves with at least one tab of each housing half assuming a predetermined position relative to the pole system of the respective housing half and wherein alternative tabs on each half are wider and contain a slot with the remaining tabs being narrow and of a width corresponding to the width of said slots in said wider tab.
Claim 6
Dependent Claim
120 words
In a housing for a fractional horsepower A-C motor of the type comprising two housing halves of the same diameter which are fitted together with each housing half containing poles forming a pole system for the A-C motor, an improved form of construction, comprising a plurality of tabs on each of the housing halves bent perpendicular to the plane of the housing halves with at least one tab of each housing half assuming a predetermined position relative to the pole system of the respective housing half and wherein alternative tabs on each half are wider and contain a slot with the remaining tabs being narrow and of a width corresponding to the width of said slots in said wider tab.
Claim 7
Dependent Claim
17 words
A housing according to claim 4 wherein said slot is wider at the base of the tab.
Claim 8
Dependent Claim
18 words
A housing according to claim 4 wherein the length of tabs is shorter than the axial housing height.
Claim 9
Dependent Claim
13 words
A housing according to claim 4 wherein the two housing halves are identical.
