Abstract: 11,627. Bertram, W. E. May 13, 1910, [Convention date]. Magazines, escapements, and matrix-ejecti n g apparatus; keyboards; driving-mechanism. - In machines of the kind described in Specification 17,135/93, the magazine is arranged to hold two or more founts of matrices, and adjustable mechanism is provided for releasing and assembling matrices of any fount. (1) In the arrangement described, the magazine has two groups of channels G, H, Fig. 2, for two founts of matrices. The magazine pawls D, . Fig. 4, are provided with shoulders E for engagement by the oscillator F, and are, as heretofore, held in normal position by detents 10 against the pull of springs 9. (2) The detent-levers 18 are mounted on a shiftable carrier 12 sliding in guides and adjustable by means of a hand-lever to enable matrices to be released from either group of magazine channels. The bars 21 that actuate the detentlevers are also mounted on the carrier 12, and the bail-rods B are elongated so as to remain in engagement with the bars 21 in both positions of the carrier. The oscillator F, which returns the pawls D to normal position, comprises a frame 1 pivoted on an axis 2 supported by brackets 3 on the carrier 12, and is actuated by a cam-shaped gear 6, which is adapted to engage a constantly-rotating gear 7. (3) The space-box is in two sections, of which one R is fixed and the other L, Fig. 2, is movable with the carrier 12. The spacers are supported by their hooks on inclined rails 144, 67, which are continuous in one position of the carrier. When the two sections of the box are separated, a detent 145 holds back the spacers in the stationary section of the box. (4) The spacers are fed into the composing-box by an ejector blade through a slot 69 closed by a spring- pressed gate. The ejector, which is mounted on the carrier 12, is actuated by a spring when released by the depression of the space-key, and is retracted to normal position by the oscillator. (5) After the casting-operation, the spacers are delivered on to a rail 122, from which they are disengaged one at a time by mechanism connected with the space-key, whereupon they fall down an inclined shoot 126 into the space-box. Matrices. The alining-notches b, Fig. 25, of the matrix-bars are extended inwards and upwards to form rounded recesses c, which are engaged by a rib on the assembling - rail, whereby wear of the alining - surfaces of the notches is prevented. Each matrix-bar has in its lower end a recess d into which projects a hook e, which engages with the arresting-stop and prevents rebounding of the matrix - bar during assembling. Spacers are provided with a rounded recess g, Fig. 27, to engage the rib on the assembling- rail. Assembling and alining matrices. - The composing - box 32, Fig. 2, is mounted on the movable carrier 12 and has a guide 36 for the falling matrices. The box has two wings 37, Fig. 17, which turn on pivots 38 and may be opened by means of a handle 57 to permit removal of a matrix. The detent which supports the assembling line is simultaneously retracted. The matrix-arresting stops are in the form of blades 43, Fig. 14, mounted on a pivot 42 and operated by bars 39 connected with the key-board. To each blade is pivoted a spring- pressed pawl 48, which enters the recess d in the foot of the matrix-bar and engages the hook e to prevent rebounding. The actuating- bars 39 are reset by a yoke operated by a bailrod, which is connected by links 39<c>, 39<d>, Fig. 4, to the lower end of the oscillator. The plunger, which removes the matrices from the composing- box to the assembling-rail, reciprocates through a slot in the rear wall of the composing-box, and is connected bv a lever and a link 50<a>, Fig. 4, to the oscillator. The assembling-rail P, Fig. 23, is attached at one end to the composing-box and is mounted to slide lengthways. The rail has a rib 153 which fits the recesses c in the matrix-bars, and the part of the rail which enters the notches b is smaller than the notches so that wear of the upper and lower surfaces of the notches is prevented. The front end of the line is supported by a finger 164 carried by a ring Q which can slide without rotation on a tube 162. When the line reaches the proper length, a detent 173 is tripped by the ring Q, and the tube 162 is rotated by a spring so that the finger 164 is raised out of the line. When the line is transferred to the casting point, the finger 164 is returned to initial position by a spring. The alining-rail S, Fig. 25, forms a continuation of the assembling- rail, but is only movable to and from the matrices. The rail has for part of its length a rib similar to the rib 153, the remainder having a rectangular edge which closely fits the notches b in the matrix-bars.
