Abstract

156,350. Druitt, P. W., and Gilpin, W. H. Oct. 17, 1919. Single-type composing and casting machines ; matrices.-In machines such as described in Specifications 1903/00 and 11870/13 in which the matrices of a justified line are separated and presented singly to the mould, means is provided for casting from matrices having more than one character. The presentation-plunger a, which clamps the matrices against the mould, has a vertically sliding head a<1> which may engage a fixed aligning-stopc<0> on the mould or may be supported at a higher level, when the lower characters of the matrices are to be used, by means of an aligning-bar b mounted to slide on the plunger. When the upper character of a matrix is to be cast from, the bar b is retracted and the head a<1> is depressed on to the stop c‹ by a lever f and a spring-pressed plunger f<2> carried by a vertically moving slide i. The head a' is raised, as the plunger a retires, by a stop g which engages an incline f<1> on the lever f. The change in position of the bar b is effected by a cam h carried by the plunger a and adapted to be rotated by a ratchet wheel h<1> and a pawl i<o> carried bv the slide i. When the slide i reciprocates the plunger is normally in the advanced position so that the ratchet-wheel is not engaged by the pawl. When a change of fount is required, a special controller-matrix is inserted in the matrix line whereby the plunger a is prevented from advancing and the bar b is shifted by the ratchetmechanism.
