Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 219 words
In a socket assembly for a plug-in electrical heating element for a stove, comprising a socket member of rigid dielectric material defining horizontal sockets configured to receive contact members on the heating element and containing conductor elements resiliently engageable with said contact members, and a guide and carrier member which loosely and interlockingly embraces said socket member so as to support the latter whilst permitting a limited degree of pivotal and translational movement relative to the guide and carrier member, said latter member also defining the walls of a generally horizontally extending guide passage through which said contact members must be passed to reach the sockets in said socket member, the walls of said guide passage receiving and being engageable with a grounding and locating member on the heating element from which member the contact members project, the improvement in which inwardly projecting shelves are formed on the side walls of said guide passage having an inward and rearward extent such as to engage the bottom of the grounding and locating member and prevent it from approaching the bottom wall of the passage and the heating element from being lowered to a horizontal position until the contact members are fully engaged in the sockets and the grounding and locating member has passed beyond the rear ends of the shelves.
Claim 2
Dependent Claim 219 words

Claim 3
Dependent Claim 41 words
A socket assembly according to claim 1, wherein the guide and carrier member is a one piece sheet metal pressing, and the shelves are formed by integral inturned flanges at the bottom edges of the side walls of the guide passage.
