When were ceiling rose junction boxes invented?

Arran Cameron
When were ceiling rose junction boxes invented? They appear to be post WW2 as I have been unable to find any that are older. The ceiling roses I have from the 1920s and 30s are either purely mechanical or have terminals just for live and neutral for the light fitting. Were ceiling rose junction boxes intended as a cost saving feature when constructing houses?

    Paul,

    Following on from your comments I have had a look at the BSI website myself and have found the two editions of the standard you mention:
    BS 67:1987. Specification for ceiling roses.
    BS 67:1969. Specification for ceiling roses.

    However the BSI website also has the following earlier editions of the standard:
    BS 67:1938. Specification for two and three-terminal ceiling roses.
    BS 67:1929. Specification for two and three-plate ceiling roses.
    BS 67:1914. Specification for two and three-plate ceiling roses.

    I think this means we can conclude ceiling rose junction boxes were invented prior to 1914 (the invention would need to predate the production of the first standard) though it does not help in identifying the time the loop arrangement was introduced.

    (By the way, if anyone is really interested you can still buy the 1914 edition of the standard from BSI......)
