Improvements in and relating to Facia for Electrical Instruments.
We, MAX BYNG, of 71, Queen Victoria Street, in the City and County of
London, Electrical Engineer, and RICHARD PENTNEY EIDSFORTH, of Peel Works,
Adelphi, Salford, in the County of Lancaster, Electrical Engineer, do hereby de-
clare the nature of this invention to be as follows:-
Our invention relates to certain improvements in facia for electrical instru-
ments, such for instance as indicators, volt and ampère meters, and the like,
and has for its object the employment of metal plates especially treated to serve
the purpose.
In carrying our invention into effect we use a metal plate of suitable thickness
and coat it with ink or colouring matter in the ordinary process of colour print-
ing, the indicating letters, figures, or numerals being included in the printing
operation which may be performed by a prepared stone or series of stones, or
any method in use for printing in two or more colours.
We print the indicating figures, numerals or the like directly upon the plate
forming the facia of the instrument, but we prefer to attach such figures or
numerals to a prepared plate by screwing, rivetting or any equivalent means for
such attachment. These figures or numbers may be printed upon metal strips
of any suitable shape, to conform to the holes of indicators, or to the scale of any
electrical instrument or appliance.
The essential feature of our said invention is in the employment of metal plates
which have been subjected to a printing process, as herein before described.
