Abstract: 29,422. Walker, A. H., [International Typograph Co.]. Dec. 20. Type-bar making machines; magazines; matrices; assembling and distributing matrices.-Relates to machines in which the matrices are suspended from continuous guides, and consists in the provision of a number of magazines any one of which may be brought into register with the guides ; in an improved construction and arrangement of the guides ; and in improved means for assembling the matrices at different levels. The ends of the guides B, Fig. 2, are separated by a gap which is filled by the magazine in use. The magazines A<1>, A<2>, A<3>, Fig. 3, are superposed and are connected together by a frame which slides on vertical guides A". Any magazine may be brought into use by means of a chain and pulley system operated by a crank handle. The guides B are preferably flanged or L-shape in cross-section, and for the greater part of their length are arranged in two vertical tiers, the upper guides serving to hold the matrices in position upon the guides below. In connexion with the uppermost guides and where the guides diverge, supplemental holding-means, such as vertical plates engaging notches in the tops of the matrices, may be employed. In order that the magazines may have an inclination of about 20 degrees, the converging parts of the guides, which lead to the assembling position, are nearly vertical and have overlying plates B<50>, Fig. 9, to hold the matrices in position. The casting-mechanism is located at the horizontal position of the guides. Each magazine is semicircular in form and comprises a series of matrix-supporting hangers D, Fig. 9, arranged in groups of six, each group corresponding to one of the guides B. The matrices are retained on the hangers by escapements and, when released, fall upon discharging-plates D<1> which register with the guides. In advance of the assembling point, the guides are offset vertically, as shown in Fig. 16, and are reduced in height and flared so as to permit of vertical movement of the matrices. At this point, the matrices fall upon a vertically - adjustable switch G<2>, by means of which they can be caused to engage an alining- rail G at either of two levels. The switch G<2> and a guiding-plate G<1> in alinement with it engage notches in the feet of the matrices. The matrices are of eight different lengths and are all provided with a suspending-hook Y<3>, which is offset rearwardly to permit of greater freedom of movement of a matrix on its guide. Matrices that travel on the same guide are delivered to the different hangers of a group by means of a separating-hook Y<4>, Fig. 22, which is absent in one group of matrices and occupies different positions in the other groups. The hooks Y<4> co-operate with bars F, Fig. 9, of varying length which conduct the matrices to the proper hanger. Escapements.-Each magazine carries its own set of escapements which are of ordinary form and are operated by push-rods which, when a magazine is in position, register with a set of rods operated by the keys.
