Abstract: 387,118. Type-bar-making machines. HART, H., 9, Kingsway, London.-(Mergenthaler Linotype Co. ; 29, Ryerson Street, Brooklyn, New York, U.S.A.) Jan. 25, 1932, No. 2223. [Class 100 (iii).] Assembling matrices.-Relates to means for handling lines of matrices which are composed in hand-sticks, and particularly lines containing either regular matrices having projecting ears or the larger special matrices X, Fig. 15, which are formed without projecting ears. A short composing-stick, having a single compartment, comprises a bottom wall J<2>, Fig. 19, a side wall J<3>, and two end walls J<5>, J<6>, which are pivoted in the side wall, so that they can be rocked out of line-retaining position. The end walls are of triangular form and are pivoted at their lower corners, their free ends being adapted to engage in slots in corner members J<7>, J8. The stick is formed with a recess j<11> to receive the upper ears of the regular matrices, and with a pair of grooves j<12> to engage their lower ears and support them at either of two levels. A scale J<12> facilitates the composition of the matrices, which are assembled between a pair of blank matrices X<1>, Fig. 4. The blank matrices are held in position by hook-shaped sliding detents j<8>, which engage in recesses therein. The line is clamped in the stick by a screw J<11>. A longer stick K, shown in plan in Fig. 20, is adapted to hold two lines of matrices, and is divided into two compartments by a partition K<10>. The left-hand compartment K<1> is open at one side, but the right-hand compartment K<2> is partially closed by a low wall K<11>. The end wall K<8> and the partition K<10> are pivoted, as in the case of the end walls of the stick J, but the other end wall K7 is fixed, and has an aperture to facilitate the transfer of the line to the left-hand compartment. The matrix lines are transferred from the sticks to the vertically movable transporter or elevator B, Fig. 3, of the machine by a reciprocable carriage F sliding on guides G. The carriage has depending line-engaging fingers F<5>, F<6>, and is operated by means of a handle F4. The sticks are located in position on a table H, shown in plan in Fig. 4, by a locating-device comprising a slide R<1> carrying a crossbar R<3>, which is adapted to fit between the end walls J<7>, J<8> of the stick J, and between the corresponding members K<8>, K<10> of the stick K. The stick is then pushed rearwards until arrested by banking-screws 0, O<1> with the matrices in line with the transporter. The end walls J7, J8 are tilted up by engagement with the fingers F5, F<6> of the transfer carriage, which then embrace the line between them. The blank matrices Xl are released by studs P, P<1>, which push back the detents j<8>. The matrix line can then be transferred through an intermediate channel L to the transporter B. The stick is held against the banking-screws during the transfer by a segmental rotatable wedge M, which projects through an aperture in the table H and is operated by means of a handle M<3>. After the casting, the line may be returned to the stick, or, when several sticks are employed, the first line may be ejected from the transporter into a receptacle on the other side by a finger F<9> on the transfer carriage, the succeeding line being by the same movement delivered to the transporter by the fingers F<5>, F<6>. In the case of a long stick K, the left-hand matrix line is first delivered to the transporter, and the transfer carriage is returned. The right-hand transfer finger F<6>, which is vertically movable, is then raised, and the righthand line is moved into the left-hand section of the stick for subsequent delivery to the transporter.
