Some years ago a patent was taken out for making needles of this kind, by Mr. William Bell, of Walsall; and as the manufacture of them has ever since been continued with success, we shall close the present subject by subjoining that gentleman's brief specification verbatim. "The method by which I make needles, bodkins, fish-hooks, knitting-pins, netting-needles, and sail-needles, is by casting them with steel, or common fusible iron, called pig or cast-iron, into moulds, or flasks, made with fine sand; or, otherwise, I make stocks or moulds, of iron or steel, or any other composition capable of being made into moulds; on which stocks or moulds I sink, engrave, or stamp, impressions of the said articles. Into these I pour my melted iron or steel (I prefer for my purpose sand casting), and prepare my iron or steel as follows: - I melt it in a pot, or crucible, in small quantities about the veight of twelve pounds (and upwards to twenty pounds), the more con veniently to divest it of its heterogenous particles, and to purify it from its earthy or sulphureous qualities.
When the iron has attained a proper heat, I take charcoal-dust, mixed with lime or common salt, which I throw into the pot of melted iron; and, by frequently stirring it with an iron rod, I bring to the surface of the iron a scoria, which I frequently skim off, and thus bring my iron into a refined state; I then pour it into the mould before described. The articles being thus formed, are capable of being softened, hardened, or tempered, in the usual way, by which needles, bodkins, fish-hooks, knitting-pins, netting-needles, and sail-needles, have, heretofore, been manufactured; therefore, the principal merit of my Invention is in casting them instead of making them in the usual way."
