Abstract: 11,628. Bertram, W. E. May 13, 1910, [Convention date]. Magazines for type-bar making machines. - In machines of the kind described in Specification 17,135/93, provision is made for two or more founts of matrices. In the form described, the magazine has two sets of channels, each set consisting, for example, of seven channels, those of the two sets preferably alternating. Two sets of distributing - chambers 13, 14, Fig. 2, containing inclined rails 15, return the matrices to the magazine. Escapements and matrix-ejecting apparatus. - (1) Each magazine channel has a delivery gate or pawl 16, Fig. 2, provided with a follower arm 17 and a lug 18 which is engaged by a detent 19, the pawl being thereby held in operative position against the pull of a spring 20. (2) The descent of the matrices is assisted by spring-pressed plungers 119, Fig. 16, which bear upon the tops of the leading matrix-bars. After each release of a matrix, the corresponding plunger is raised by a common bar 122 mounted on a rock-shaft 120. Keyboards and driving-mechanism.-The keys operate a single set of actuating-bars 44, Fig. 2, of which the rear ends are movable laterally to enable matrices of either fount to be released. The bars 44 engage by means of notches with the detents 19 of the magazine pawls 16. The bars 44 are reset by a reciprocating bar connected to a rocking frame 55, which is operated by the oscillator cam shaft 29. The magazine pawls 16 are reset by an oscillator 24 pivoted on the main frame 9 and having at its upper end pawls 26 which engage the lugs 18. A roller on the oscillator is engaged by a cam on an intermittently-rotated shaft 29. The shaft 29 is driven through a clutch, which is engaged by the backward movement of the pawls 16, and is automatically disengaged after one revolution. Matrices. - The matrix-bars 1, Fig. 28, are all of the same length, and are provided with suspending-hooks 4 and with one or more distinguishing - lugs 5 at the top, by means of which distribution is effected. Spacers.-The supporting-hooks of the spacers are at a different level from the hooks of the matrices when the spacers are supported by the alining-bar. Assembling matrices.-The composing-box is movable, and is automatically positioned beneath the magazine channel from which a matrix is to be released. It then moves on and delivers the matrix to the assembling point. The box is mounted on a carriage 63, Fig. 11, which slides in a recess in the front plate 64 of the machine. The front of the box is formed by a pivoted wing 74, shown in plan in Fig. 10, having a blade 75 which guides the matrix into the box. A guard 76 supports the matrix when the wing 74 is retracted for the ejection of the matrix. The right-hand side of the box is formed by a plate 80 carried by a slide 77, which is movable in the carriage 63, a spring 79, Fig. 10, being interposed between the slide and the carriage. When a key is depressed, the carriage is released and is moved by a spring until a stop on the slide 77 meets the projecting end of the actuating-bar 44 corresponding to the depressed key, and is thereby arrested with the composing-box beneath the required magazine channel. A supplementary stop adjusted by hand serves to arrest the box beneath the magazine channels containing matrices of the other fount. After the reception of the matrix, the carriage 63 continues its movement until arrested by the wall 111 of the opening in the plate 64. The slide 77 then moves in the carriage, compressing the spring 79. The wing 74 is thereby retracted, and a spring-pressed wing 85 is pushed back, and the matrix is ejected between detents 89 on to an assembling-bar 65. The carriage is then returned to normal position by a cam on the shaft 29. Distributing matrices. - The matrices and spacers are raised prior to distribution by an elevator movable vertically on a standard 133, Fig. 25. The elevator is in two sections, one, 137, of which has a rail 147 to receive the spacers, the other 148 being moved laterally on the section 137 as it ascends, and having a rail 150 to support the matrices. Two pushers, one of which is actuated through a spring by the other, remove the matrices and spacers from the elevator on to stationary rails, one of which conducts the spacers to the space - box. The matrices, while under the influence of the spring-pressed pusher, are detached one by one from the line, and are moved edgeways by a reciprocating member along a rail 186, Fig. 24, past the ends of the distributing-chambers of the magazine. The matrices are raised by lifters 192 and, if the lugs 5 on their upper ends correspond with notches 185 in a transverse bar 184, they enter the chambers and are supported by their hooks on the rail 15.
