Wrench. Tow. Tap. Rimmer. Clamps. Pliers. Drill Stock.
The clamps are a sort of vice with grooved holes, for holding the taps and metal joints firmly while they are filed or otherwise prepared; the drill stock is used for boring small pipes in order to make a branch to some other direction, and the drill brace is intended for boring the main pipes, under which the large hooks are placed while a stock and bit attached to the upper screw makes the hole; the ordinary braces are fitted to a ratchet or cog wheel at one end, and are also used for making incisions by being worked backwards and forwards.
Drill Brace. Braces. Stocks and Dies.
The several kinds of burners are pierced or cut in such a way as to make the flame from the gas of different shapes, such as fish tail, cock spur, star, or argand, the names of which tell pretty well in what shape they appear. Small rooms are sometimes fitted with “telescopes” instead of chandeliers, the telescope being one tube sliding within another, and the space carefully filled with a properly adjusted cork or some other flexible and impervious substance. Bedrooms, and apartments where light is required at the walls or chimney pieces, are furnished with brackets, which either simply project from the wall, or are made with an arm moving on a ball and socket joint. The manufacture of the various portions of the apparatus used in gas fitting will be mostly found described under the trade of the Brassfounder.
