Improvements in Electrical Ceiling Roses.
CHARLES LEIGH CLARKE 7 South Parade, Manchester Electrician WILLIAM
PAUL THURMANN 11 Great Ducie Street, Manchester, Electrician both in the
County of Lancaster do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to ensure a greater safety against short circuiting
of the different connections to provide means for suspending the flexible cord, so
as to take the strain off the connected ends of the flexible wire, and to prevent the
flexible cord coming in contact with the fuse wire. To do this we provide the said
ceiling rose with a short tube or hollow bridge formed longitudinally at about the
centre on the connecting surface or face inside the said ceiling rose. The said
surface or face is in the middle slightly hollowed out, so as to form a groove or
slot and across which the tube or hollow bridge is placed. The fuse wire passes
through the said tube or hollow bridge and the flexible cord is twisted round
the outside of the said tube and passes through the said groove or hollow space
below the said small tube or hollow bridge.
Dated this 21st day of January 1895.
