Abstract: 23,559. Walker, A. H., [Mergenthaler Linotype Co.]. Dec. 4. Magazines, escapements, and keyboards for typebar-making machines. Relates more particularly to machines of the kind described in Specification 24,831/13 having a number of stationary magazines, any one of which may be brought into use by means of fount-keys. (1) The escapements of all the magazines are operated by projections E<2>, Fig. 6, on a single set of reeds E<3>, which are actuated from the keys through projections E<5>, levers E<6>, and reeds E<7>. The fount-keys act on rock-shafts C which lock the escapements, and on flaps D which close the mouths of the magazines, as heretofore. According to the invention, the fount-keys and their connexions, the flaps D and the reeds E' are carried by the pivoted front plate or frame G through which the released matrices pass to the assembler. As the frame G begins to move, the reeds E<3> are depressed to disengage them from the escapements and from the levers E<6> by a fixed bar E<30>, which engages curved arms E<20> on the reeds. When the frame G closes, bevelled projections thereon engage in notches in the magazines to effect proper registration of the parts. The rock-shafts Care connected with their actuating-means by tongues and grooves so that they are automatically disengaged when the frame G is opened. The fount-keys B, Fig. 18, are held down, when depressed, by hooks G<10> on a sliding plate G<9> so arranged that depression of a second key releases the previous one, as heretofore. According to the invention, the outward movement of the frame G also acts upon the plate G<9> so as to release any key which may be depressed. The plate may also be operated by means of a finger-piece. Depression of more than one key at a time is prevented by a series of members G<8>, Fig. 20, pivoted at their upper ends so as to have a limited lateral movement which accommodates only one key-lever. The frame G is held in closed position by a bolt, the movement of which may be caused to depress the reeds E<3> and operate the plate G'. (2) The escapements are arranged in banks F, Fig. 11, which are readily detachable from the respective magazine and are secured by hooks F<1> and pins F<2> on plates F<3> which have a limited sliding movement on the magazines. When in position, each bank is held by a pin F<7>. Removal of a bank is prevented until the matrices are locked in the magazine by the usual bar, which is passed transversely through it and depresses a spring pin, which normally prevents movement of the plate F<3>. The rock-shafts C are carried by the banks F and are locked against rotation when the magazine on the bank is removed by a spring plunger F<13>. (3) Each magazine is held in position on the machine by a slide H, Fig. 9, which normally lies in front of a rib H<2> on the bottom of the magazine, as heretofore. A movable stop arrests the slide in an intermediate position, in which it is engaged by a stop H<3> on the magazine, so that the magazine is arrested after a limited forward movement. (4) When sorts or extra matrices are employed, they are distributed according to fount and delivered through separate tubes to stacking-devices or receptacles.
