Abstract
316,347. fierpont, r. H., and Lanston Monotype Corporation, Ltd. April 28, 1928. Type-casting machines.-Means is provided for positioning a matrix relatively to the mould with a variable travel, according to the product to be obtained, so that either a matrix may be pressed on to the mould, or a matrix or cone may be projected into the mould cavity, as in the casting of hollow quotations. The matrix is positioned by a reciprocating plunger A, which is depressed by a spring H, and is raised by a bell-crank lever B, operated by a sliding bar E. The pivot of the lever B is carried by an eccentric C, which can be rotated by means of a handle C<2>, so that an extra lift is given to the matrix. The matrix is clamped on the mould by an inclined surface E<5> on the bar E, which is driven over a similar surface A<2> on the plunger A.
