494,872. Type-bar-making machines. MERGENTHALER LINOTYPE CO. Jan. 25, 1938, No. 2359. Convention date, April 28, 1937. [Class 100 (iii)] Distributing matrices.-Machines having a column of magazines, which is movable to bring different pairs thereof into operative position, are provided with a fount-selector having automatic means for adjusting it as different pairs of magazines are moved into operative position, such automatic means being themselves adjustable, so as to vary the position to which they will move the fount-selector in accordance with variation in the founts carried by the magazines. Fountrejecting means are also provided for preventing the passage of any matrices not appropriate to either magazine of the pair in use. The matrices to be distributed are fed to an upper distributer U, Fig. 1, which is provided with an adjustable bridge U<6>, Fig. 6, to co-operate with notches in the feet of the matrices. Matrices unprovided with a notch that registers with the bridge are supported at a higher level, and engage the bar of the upper distributer, by which they are delivered to the lower magazine of the pair. Matrices having a notch that registers with the bridge fail to engage the upper distributer-bar, and fall down a shoot U<9> leading to the distributer U<1> of the upper magazine. A fount-distinguisher, for rejecting matrices not appropriate to either magazine, comprises a rib U<11>, Fig. 5, located in the upper distributer-box just in advance of the matrix-lifter. Fountdistinguishing notches are located in the same position on matrices of a pair of founts, and matrices having notches which do not register with the rib are arrested thereby, and the distributer is stopped. The fountselecting bridge U<6> is carried by a slide U<12>, and is adjusted against spring pressure by a lever U<14>. The fount-distinguishing rib U<11> is similarly adjusted by a second lever U<24>. The levers are operated, as the magazines move, by either of two pairs of stepped discs V, V<1> and V<2>, V<3>, which are associated with the upper and lower pairs of magazines respectively. The discs are angularly adjusted by hand into such positions that, when they come into action, they locate both the fountselecting bridge and the fount-distinguishing rib in positions appropriate to the founts contained in the magazines. Each disc has two sets of steps designed for use with existing matrices, which have either a fount-distinguishing notch located in one of twelve different positions, or a fount-selecting notch located in one of eight different positions. A second notch is cut in the matrices, where required, to enable them to co-operate with both the fount-selecting bridge and the fount-distinguishing rib. Specification 445,899 is referred to.
