Publisher's Synopsis
Excerpt from The London Journal of Arts, Sciences, and Manufactures, and Repertory of Patent Inventions, Vol. 30
These improvements in manufacturing types and other similar raised surfaces for printing, consist in a novel ar rangement of machinery, by which matrices and moulds, of the like kind to those commonly used in casting types, may be worked through the agency of mechanism, instead of the ordinary mode of casting types by the hands Of a workman. In this novel arrangement Of machinery, a pan or vessel, con taining molten type-metal, is placed over a furnace contiguous to which the mould with the matrix is mounted with certain appendages; whereby the melted metal is forced into the mould, for the purpose of casting a type; and when such type has been cast, the mould is thrown open for the discharge Of the type, and closed again ready for a second operation.
In Plate II., fig. 1, is a front elevation Of the machine, complete and in working condition; fig. 2, is a side elevation Of the same, taken at the left-hand Of fig. 1. A horizontal view Of the machine as it would appear from above, is represented at fig. 3; the mould and its frame and appendages being in this figure removed, to shew the parts below more clearly. A vertical section of the machine, taken through the middle Of the mould, the furnace, and the pot of melted type-metal, is shewn at fig. 4; this section being taken in the dotted lines 2, z, Of figs. 2, and 3 -and a similar section Of the machine, taken in the dotted lines Y, Y, Of figs. 2, and 3, is repre sented at fig. 5.
