King Street Birmingham Lamp Manufacturers, do hereby declare the nature of
this invention to be as follows:-
Our invention relates to the sockets of velocipede lamps by which these lamps
are fitted on to the lamp brackets of velocipedes and our object is to make a simple
form of socket which is self adjusting to brackets of various sizes or thicknesses.
We use the ordinary flat socket which is preferably lined with india rubber, leather
or other suitable non-metallic material and we fix a bowed spring made of flat steel,
hard brass, German silver or other suitable metal through the socket so that it
forms a flexible false side to the socket and when the socket is put on to a bracket
the latter is gripped between the flexible or springy false side of the socket and the
fixed side.
