Claim 8

A holder for an electric light bulb, said bulb having a base with a center contact and a side contact, said holder comprising a socket at one end into which said bulb is pressed, two terminals for connection of electric conductors at the opposite end of said holder, said terminals being carried by a transverse plate at said opposite end, and a transverse, fixed wall intermediate said ends, one of said terminals being located in the center of said holder and the other at one side, a first, central contact element in the form of a contact pin mounted for movement through said fixed wall into contact with said center terminal by said bulb when pressed into said socket with said center contact in engagement with said first, central contact element, a spring resiliently holding said central contact element out of engagement with said center terminal unless engaged by a bulb, a fixed, lateral spring contact with one end on one side of said wall for engaging said side contact and extending toward said opposite end of said holder, with its other end on the other side of said wall, a second contact element carried by a transverse insulating carrier member mounted on said first contact element so as to be tiltable and restrictedly displaceable with respect thereto along the axis of the lamp holder, said second contact element being movable into engagement with the other end of said lateral spring contact and said side terminal by movement of said first contact element into engagement with said center terminal, said transverse plate together with said wall and side walls extending therebetween forming an enclosed housing for said carrier member and said second contact element, said enclosed housing being removable from the holder as a unit together with the lateral contact spring and said first contact element, said side walls being fixed to said wall and depending skirt-like therefrom.

Claim 9

A holder for an electric light bulb, said bulb having a base with a center contact and a side contact, said holder comprising a socket at One end into which said bulb is pressed, two terminals for connection of electric conductors at the opposite end of said holder, said two terminals carried by a transverse plate at said opposite end, and a transverse fixed wall intermediate said ends, one of said terminals being located in the center of said holder and the other at one side, a first, central contact element mounted for movement through said fixed wall into contact with said center terminal by said bulb when pressed into said socket with said center contact in engagement with said first, central contact element, a spring resiliently holding said central contact element out of engagement with said center terminal unless engaged by a bulb, a fixed, lateral spring contact with one end on one side of said wall for engaging said side contact and extending toward said opposite end of said holder, with its other end on the other side of said wall, a second contact element mounted on and movable by said first contact element and insulated therefrom, said second contact element being movable into engagement with the other end of said lateral spring contact and said side terminal by movement of said first contact element into engagement with said center terminal, said transverse plate together with said wall and side walls extending therebetween forming an enclosed dustproof housing for said carrier member and said second contact element, said enclosed housing being removable from the holder as a unit together with the lateral contact spring and said first contact element.
