B. Verity and Sons
1819 Business started[1]
1825 Company established as B. Verity and Sons at 31 King Street, Covent Garden.
1890 Provided the electrical installation for the new D'Oyly Carte theatre. There were three 140 psi locomotive-type boilers and three Willans 135 ihp compound engines running at 350 rpm, driving Siemens generators giving an
output of 650 amps at 110V. Each engine had a steam separator fixed on its own bedplate. The engine foundations were completely isolated from the walls to prevent transmission of vibration. Three Berryman heaters were installed, one for heating feedwater, the others for house heating. These were served by grease-separating apparatus. Batteries were installed for use during the daytime.
In the ventilation of the theatre three Verity silent
air propellers were used, each driven by an independent
electric motor, two of them exhausting foul air from
the auditorium and one for forcing fresh air into the
building. After leaving the fan the air passed over a
coil of pipes and along conduits in the basement, and
entered the auditorium at suitable places. The coil could
be used either for heating or cooling the air.
The whole of the work was carried out from the designs and
under the superintendence of B. Verity and
Sons, of King-street, Covent Garden, who also erected the plant.[2]
1891 The works were transferred to Aston, Birmingham
1896 The works were considerably enlarged
1896 Incorporated under the name of Veritys Ltd. The company was registered on 21 October, to take over the business of electrical manufacturers, engineers and contractors of Verity of London and Manchester. [3]
