It is very beneficial to regulate the pressure at which gas reaches the burners, and many complaints of impurity of the air of a room, caused by gas, arise from this want of regulation of pressure. It can be attained by the use of a governor, placed either at the meter or in proximity to the light itself. These are of many forms. Those adapted for placing near the meter are Stott’s, Fig. 49 (174 Fleet Street, E.C.), Parkinson’s, Fig. 50 (Cottage Lane Works, City Road), Strode’s, Fig. 51 (67 St. Paul’s Churchyard), Hargreaves and Bardsley’s (Hobson Street, Oldham), Hulett’s, Fig. 52 (55 High Holborn), Peebles’ (Tay Works, Edinburgh), and Smith’s (130 Fleet Street). Self-regulating burners are the “Christianson,” made by Sugg (Grand Hotel Buildings, Charing Cross), and those made by Bolding—Heran’s patent—(South Molton Street, Oxford Street), Milne, Sons, and Macfie (2 King Edward Street, E.C.), Parkinson (Fig. 53), Peebles, and Kinnear (91 Finsbury Pavement). A little steel blade, costing only a penny, is made by W. H. Howorth, Cleckheaton, Yorkshire, for use on 2-holed burners, which has the effect of silencing a roaring flame and increasing the luminosity. Another contrivance having some of the effects of a regulator, augmenting the light and consuming the smoke (therefore lessening the contamination of the air), is the Spencer Corona, Fig. 54 (3 Hyde Street, New Oxford Street), fitting closely on the top of ordinary gas globes.
