Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
174 words
For use in a portable electric appliance cord-connected to internal terminals by a portion of the cord having separated conductors connected thereto, the improvement in a strain relief connection between the cord and appliance comprising, a housing chamber in the appliance at the entrance of the cord to the appliance and containing the conductors loosely therein, said chamber having a generally U-shap with a central fastening hole and a step portion spanning the chamber completely around the sides of the U adjacent the hole, a chamber cover having tongue means extending therefrom toward and coextensive with the step portion, a protected recess in said cover having means therein engaging said hole to secure the cover to the housing, whereby the separate loosely disposed conductors straddle the securing means anywhere in said U-shaped chamber and said tongue extends into said chamber and automatically positions the conductors in strain relief against the step portion anywhere along its length and also blocks the external cord from entering the chamber when the cover is tightened to said housing.
Claim 2
Dependent Claim

For use in a portable electric appliance cord-connected to internal terminals by a portion of the cord having separated conductors connected thereto, the improvement in a strain relief connection between the cord and appliance comprising, a housing chamber in the appliance at the entrance of the cord to the appliance and containing the conductors loosely therein, said chamber having a generally U-shap with a central fastening hole and a step portion spanning the chamber completely around the sides of the U adjacent the hole, a chamber cover having tongue means extending therefrom toward and coextensive with the step portion, a protected recess in said cover having means therein engaging said hole to secure the cover to the housing, whereby the separate loosely disposed conductors straddle the securing means anywhere in said U-shaped chamber and said tongue extends into said chamber and automatically positions the conductors in strain relief against the step portion anywhere along its length and also blocks the external cord from entering the chamber when the cover is tightened to said housing.
Claim 3
Dependent Claim
28 words
Apparatus as described in claim 1 wherein the means in said cover engaging said fastening hole extends through said tongue for maximum force between the tongue and step.
Claim 4
Dependent Claim
33 words
Apparatus as described in claim 2 wheren the sides of said chamber and tongue are formed with a curvature to nest in tightened position and place said cOnductors for distortion on the step.
Claim 5
Dependent Claim
37 words
Apparatus as described in claim 3 wherein the step in said chamber extends through the fastening hole and said tongue for aligned force on said housing, and guide means on said cover limiting movement in one direction.
Claim 6
Dependent Claim
35 words
Apparatus as described in claim 4 wherein said cover is secured to the housing by a screw and said recess is at least as deep as one-half the diameter of the head of said screw.
Claim 7
Dependent Claim
29 words
Apparatus as described in claim 5 wherein said step is formed to create substantially a right angle bend in said conductors when the cover is tightened to said housing.
Claim 8
Dependent Claim
41 words
Apparatus as described in claim 6 wherein said cord has an elongated flexible sleeve bushing surrounding said cord and anchored to the appliance, said cover having a second extending tongue cooperating with said bushing to complement the anchor to said appliance.
