Abstract
Abstract In an electric lamp, the lamp bulb has a flat pinch, on the minor faces of which there are recesses into which projections on the cap are locked. The lamp bulb is thus secured against rotation and translation in the cap, and the power leads are not under mechanical stress.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
120 words
An electric lamp having a glass bulb, a unitary sleeve shaped cap and integral means for preventing relative radial and axial movement of said cap with respect to said bulb, said means consisting of said sleeve shaped cap having inwardly-directed projections and said glass bulb having a flat pinch with two opposing major faces, two opposing minor faces, and an end face from which power leads protrude, said leads extending through said pinch to an electrical element inside said lamp bulb, said pinch being situtated inside said sleeve-shaped cap and fixed between said inwardly-directed projections in the cap, said minor faces of said pinch each have at least one recess dimensioned and configured for locking engagement with respective inwardly-directed projections.
Claim 2
Dependent Claim
120 words
An electric lamp having a glass bulb, a unitary sleeve shaped cap and integral means for preventing relative radial and axial movement of said cap with respect to said bulb, said means consisting of said sleeve shaped cap having inwardly-directed projections and said glass bulb having a flat pinch with two opposing major faces, two opposing minor faces, and an end face from which power leads protrude, said leads extending through said pinch to an electrical element inside said lamp bulb, said pinch being situtated inside said sleeve-shaped cap and fixed between said inwardly-directed projections in the cap, said minor faces of said pinch each have at least one recess dimensioned and configured for locking engagement with respective inwardly-directed projections.
Claim 3
Dependent Claim
21 words
An electric lamp as claimed in claim 1, characterized in that a peripheral edge of the sleeve-shaped cap abuts the bulb.
Claim 4
Dependent Claim
26 words
An electric lamp as claimed in claim 1, characterized in that the major faces of the pinch become narrower towards the end face of the pinch.
Claim 5
Dependent Claim
144 words
The electric lamp having a glass bulb, a sleeve shaped cap and means for preventing relative radial and axial movement of said cap with respect to said bulb, said means consisting of said sleeve shaped cap having inwardly-directed projections and said glass bulb having a flat pinch with two opposing major faces, two opposing minor faces, and an end face from which power leads protrude, said leads extending through said pinch to an electrical element inside said lamp bulb, said pinch being situtated inside said sleeve-shaped cap and fixed between said inwardly-directed projections in the cap, said minor faces of said pinch each have at least one recess dimensioned and configured for locking engagement with respective inwardly-directed projections, at least one of the minor faces of the pinch having bevelled edges where it joints the major faces, said recesses being provided in said edges.
Claim 6
Dependent Claim
144 words
The electric lamp having a glass bulb, a sleeve shaped cap and means for preventing relative radial and axial movement of said cap with respect to said bulb, said means consisting of said sleeve shaped cap having inwardly-directed projections and said glass bulb having a flat pinch with two opposing major faces, two opposing minor faces, and an end face from which power leads protrude, said leads extending through said pinch to an electrical element inside said lamp bulb, said pinch being situtated inside said sleeve-shaped cap and fixed between said inwardly-directed projections in the cap, said minor faces of said pinch each have at least one recess dimensioned and configured for locking engagement with respective inwardly-directed projections, at least one of the minor faces of the pinch having bevelled edges where it joints the major faces, said recesses being provided in said edges.
Claim 7
Dependent Claim
128 words
An electric lamp having a glass bulb, a sleeve shaped cap and means for preventing relative radial and axial movement of said cap with respect to said bulb, said means consisting of said sleeve shaped cap having inwardly-directed projections and said glass bulb having a flat pinch with two opposing major faces, two opposing minor faces, and an end face from which power leads protrude, said lead extending through said pinch to an electrical element inside said lamp bulb, said pinch being situated inside said sleeve-shaped cap and fixed between said inwardly-directed projections in the cap, said minor faces of said pinch each have at least one recess dimensioned and configured for locking engagement with respective inwardly-directed projections, a peripheral edge of the sleeve-shaped cap abuts the bulb.
Claim 8
Dependent Claim
128 words
An electric lamp having a glass bulb, a sleeve shaped cap and means for preventing relative radial and axial movement of said cap with respect to said bulb, said means consisting of said sleeve shaped cap having inwardly-directed projections and said glass bulb having a flat pinch with two opposing major faces, two opposing minor faces, and an end face from which power leads protrude, said lead extending through said pinch to an electrical element inside said lamp bulb, said pinch being situated inside said sleeve-shaped cap and fixed between said inwardly-directed projections in the cap, said minor faces of said pinch each have at least one recess dimensioned and configured for locking engagement with respective inwardly-directed projections, a peripheral edge of the sleeve-shaped cap abuts the bulb.
Claim 9
Dependent Claim
133 words
An electric lamp having a glass bulb, a sleeve shaped cap and means for preventing relative radial and axial movement of said cap with respect to said bulb, said means consisting of said sleeve shaped cap having inwardly-directed projections and said glass bulb having a flat pinch with two opposing major faces, two opposing minor faces, and an end face from which power leads protrude, said leads extending through said pinch to an electrical element inside said lamp bulb, said pinch being situtated inside said sleeve-shaped cap and fixed between said inwardly-directed projections in the cap, said minor faces of said pinch each have at least one recess dimensioned and configured for locking engagement with respective inwardly-directed projections, the major faces of the pinch being narrower towards the end face of the pinch.
Claim 10
Dependent Claim
133 words
