Abstract: 182,789. Meier, N. July 9, 1921, [Convention date]. Single-type composing and casting machines ; keyboards ; moulds ;metal-pumps ; trimming type.-The mould is provided with two movable jaws which are adapted to clamp the matrix between them, and to carry the cast type to a collecting-channel in which the line is composed with a limited number of provisional spacers, which are subsequently replaced by spacers cast to the proper size to justify the line. The keylevers 1, Fig. 6, act through rods 4 on levers 6 upon which rest rods 9 connected to pivoted matrix-levers 10. The levers 10 strike upon an elastic insertion 13, Fig. 1, in an operating-lever 14, which is pivoted on a slide 17 carrying one jaw 18 of the mould. The lever 14 is thereby disengaged from a support 16, and the jaw 18 clamps the matrix against a second mould-jaw 19 carried by a slide 45. The matrix is centered by a sliding rod 43, which enters a hole in the matrix-lever 10. The movement of the slide 17 permits an arm 21 to rock on its shaft 22, and to operate the pump-rod 29 through a lever 28. An arm 35 on the shaft 22 carries an eccentric toothed wheel 37 into gear with a continually rotating wheel 38, whereby the arm 21 is retracted, and the jaws 18, 19 are caused to remove the cast type from the mould. The burr formed in the jet-orifice 33, Fig. 6,'is cut off by a knife, and other knives 48, 49, Fig. 9, remove the burr formed between the matrix and the mould 34. The type is brought opposite to an ejecting-channel 51, Fig. 9, through which it is driven by an ejector 59 into a line-assembly channel 65. A reciprocating pusher 63 advances the type in the channel against a weight-controlled slide 119. The segment 135 in which the matrix-levers are mounted can be shifted for change of fount, and can be removed and exchanged. Justifying type; galley-mechanism.-Provisional spacers are inserted between the words of the line by depression of a space-key 66, Fig. 6, which acts through a rod 68 and a feed-slide 71 to eject a spacer 70 into the line-channel. After a certain number of provisional spacers have been inserted, the slide 71 causes the space-key to be connected to a blank-matrix lever 10 so that spacers of uniform size are cast to form the remaining word-spaces. The previously cast and justified line is transferred to a galley 80, Fig. 9, by depression of a hand-lever, which acts through a link 82 on a line-pusher 85, the front wall 91 of the line channel being previously lowered. A line-conveyer 100 provided with a hook 101 is at the same time retracted into a position near the ejecting-channel 51 ready to receive the following line, and a line-supporting abutment 102 is advanced by a weight. The link 82 operated by the hand-lever also acts through a lever 106 to shift a carriage 112 and bring the provisional spacer slide 71 into line with the ejecting-channel 51, the pusher 63 being at the same time withdrawn from the line-channel. The provisional spacers are now ejected from the line one by one by the ejector 59, the line being moved to the right by the slide 119 after each ejection until a projection on the following-spacer engages the end of a slot in the wall of the line-channel. The casting of justifying-spaces to replace the provisonal spacers is effected by depression of a justifying-key, which brings down an adjustable double-wedge matrix on the mould. The adjustment of the wedgematrix is effected by a slide 128, which is positioned by an adjustable stop on the line-supporting slide 119. When all the provisional spacers have been extracted from the line, the movement of the slide 119 restores the carriage 112 and the spacer-slide 71 to normal position, and releases the hook 101 by which the line is drawn in front of the galley.
