Fire-Irons, are those instruments which are employed in the management of a fire, namely, poker, shovel,and the different kinds of tongs. As the manufacture of these articles is acknowledged to be very unwieldy, Mr. Samuel Ben-tham, of Queen-square Place, in Middlesex, obtained a patent in the month of April 1793, for a new method of making fire-irons. His invention consists in forming those instruments tubular ; the cylinders being closed at the ends, as well for strength as for keeping out dust: hence they acquire a degree of lightness, which the patentee affirms cannot be given them by any other means, with the same degree of strength. The joint of the tongs may be made in a manner similar to common ones, or with a spring-joint resembling that of sugar-tongs. The two legs are joined together by a flat, broad, semicircular plate, hardened so as to acquire a proper degree of elasticity. The ends of the tongs may be either flat, as is usual, or hollow like a spoon. The materials may be either entirely iron, or those parts which are not intended to come in contact with the fire, may be of silver, plated work, or any other metal. With respect to the poker and shovel, the ends may, for the same reason, be in separate pieces from the stems ; but as that of the poker is frequently exposed to the fire, it becomes necessary to make it, if tubular, much thicker than the stem. - The chief object of this contrivance is simplicity and lightness; but we doubt whether it is calculated for general use.
Firing-Iron, in farriery, is an instrument resembling the blade of a knife; which, being made red-hot, is applied to the hams, or to such other parts of a horse as may require it, for the purpose of cauterizing and discussing preternatural swellings, such as farcy, knots, etc. - This operation is called firing,
