Abstract: 8998. Look, W. H., and Lawless, P. C. April 21. Linotype machines.-Relates to the Mergenthaler linotype machine, (Specification No. 14,582, A.D. 1890), provided with two stationary magazines for different founts. (1) Means for opening the mouth of one magazine and closing that of the other, and an arrangement of intermediate matrix guides, as shown in Figs. 1, 2, and 3. The magazines 1, 2 are superposed and secured together by screws a or the like, and their mouths 3, 4 lie in the same oblique plane. The escapement pawls 7, 8 control the release of the matrices 14 in the magazine 2. Plates 9 on the pawls 7, 8 slide in guides in the magazine ribs 10 and carry pawls 11, 12, which act in unison respectively with the pawls 7, 8, and control the release of the matrices 13 in the magazine 1. A bar 17, disposed in a recess 16 in the part 15 of the magazines between the mouths, and guided by screw-and-slot connections 18, 19, is adapted to obstruct the mouths alternately. Cam surfaces 21, 22 on the bar 17 respectively engage with the matrix lugs 23, 24, and relieve the corresponding pawls 11, 7 of the weight of the matrices. The intermediate matrix guides 25 for the magazine 2 are provided on a bar 27 attached to the magazine 3. The corresponding matrix guides 28 for the magazine 1 are provided on a bar 29 secured to the bar 17 by dowel pins 20 and recesses 30, and connect with the guides 25, and with the channels of the assembler plate 26, just below the front edge of the bar 29. The bar 29 is rigidly attached to sliding plates 32, 33, which are operated by fingers or blades 42 on a shaft 41 actuated by means of a lever 40 and a two-part connecting-rod 38, 39. The lower end of the part 38 is forked and provided with abutments 51, 52, for engagement by a blade or finger 48 on a constantly-rotating shaft 47, according to the movement of a push-rod 37 pivoted on the part 38. Cams 57, 58 and antifriction rollers 50, 60, respectively, serve to release the abutments 51, 52 from the finger 48. The part 38 is, normally, supported out of engagement with the finger 48 by a spring detent 63. The lever 40 is mounted loosely on the shaft 41, and is yieldingly or flexibly connected to the shaft, by a buffer device 44, 46. Instead of, or in addition to, the buffer device 44, 46, a buffer device may be provided in the connecting-rod 38, 39. The part 39 is adjustably secured in a fork of the part 38 by nuts 67, bolts or screws 66, and springs 68, and each part carries an index 69. (2) Distributing-mechanism between the distributer bar and the magazine throats is shown in Fig. 6. The corresponding channels in the throats 74, 75 of the magazines 1, 2 are separated by adjustably-pivoted doors 77 maintained closed by weights 100 or by springs, or the like. Each door 77 can be locked by means of a corresponding adjustably pivoted rod 79, which carries a finger 86 normally maintained across the entrance to the channels by a weight 87 or a spring, and is provided with an abutment 103 for interposition in the path of an abutment 102 on the door 77. The axes of the corresponding doors 77 and rods 79 intersect, one or the other being cranked. The matrices for the magazine 2 are formed with a gap 78 for clearing the fingers 86, and automatically open the doors 77 and fall diagonally across the throat 74 into the throat 75. The matrices for the magazine 1 are not gapped, and strike the fingers 86 so that the doors are locked. The back-plate 88 of the throat 74 is formed with deflecting-inclines, and deflecting-ridges are provided on the channel partitions 92, 76. Lugs 107 on the partitions 76 are inserted through slots in the throats 74, 75, and are aligned and bound by wires 108. The throat 75 is provided with a back-plate 75<a> for directing the matrices feet foremost into the magazine 2. A modification is shown in Fig. 24. The throat 74 is guarded by doors 109<a>, each provided with arms 121, 110". The arms 121 project into the path of the bases of the matrices on the distributer bar 70. The arms 110<a> project into the paths of bent levers 116, which are mounted on screws 119 fixed in a bent plate 120 supported in front of the distributer screw 73, and project into the path of the front edges of the matrices on the bar 70. The matrices 13 for the magazine 1 are gapped in the base, to clear the arms 121, but are not gapped in the front edge, for contact with the levers 116 to open the doors 109<a>. The matrices for the magazine 2 are gapped in the front edge, to clear the levers 116, but are not gapped in the base, for contact with the arms 121 to close the doors 103<a>. The levers 116 are maintained in the two positions by means of a weight or spring, or by inclining the axis formed by the screws 119. In a second modification, the doors 109<a>, Fig. 24, are maintained, normally, open by replacing the arms 110<a> by weights, the levers 116 are dispensed with, and the matrices for the magazine 2 are not gapped. In a third modification, shown in Fig. 34, normally-open doors 109<a> have pin-and-slot connections 128 with counterbalanced levers 125 pivoted in a bracket or brackets below the level of the doors.
