Abstract: 10,704. Pollen, A. H., [Mergenthaler Setzmaschinen-Fabrik Ges.]. May 16. Type-bar making machines.-Relates to machines of the kind n which the magazine is vertical. The magazine 1, Fig. 2, is carried by a frame 2, which is supported on a rod 4 by means of adjusting-screws 5. The lower end of the magazine rests against pins projecting from the machine frame N, and the upper end is pressed by springs against a rail 7 carried by the frame N. The magazine can be tilted about the rod 4 and locked in an inclined position to facilitate cleaning &c. The escapementlevers n are rocked by arms 11 on key-levers 10. Assembly-mechanism. In order to reduce the height of the machine, the assembler-belt 17, Fig. 1<a>, is only slightly inclined. The guide-ribs 18 are shorter than usual and are bent more or less at their lower ends to ensure the assembly of the matrices in the proper order. The assemblychannel is formed by two rails t, Fig. 6, between which projects a resistant v carried by an arm 21 on a rod 23 which is drawn to the right by a spring. To prevent the composed line from moving to the right when a tooth-space of the star-wheel 22 is presented to it, a pinching-lever 25 is pivoted to the arm 21 and has an oval eye through which passes a rod 41. When the arm 21 commences to move to the right, a spring 44 causes the lever 25 to grip the rod 41. A signal bell 28 and a hammer 27 having an arm 26 are carried by a bracket 31 adjustably mounted on a rod 30. On the top of the resistant v is pivoted a three-armed lever 37, shown in plan in Fig. 9, on which is pivoted a lever 24. As the resistant advances, the end of the lever 24 meets the arm 26 and causes the hammer 27 to strike the bell. Further advance of the resistant is prevented d by the contact of the lever 24 with the bracket 31. On the arm 21 is pivoted a line-transferring lever 33 having a handle 35 and an arm 34. When the line is completed, the operator moves the lever 33 from the position shown in Fig. 1<a> to the position shown in Fig. 6 in which the arm 34 passes behind the last matrix of the line. A segment 45 on the lever 33 rocks the three-armed lever 37, so that the lever 24 is withdrawn from the bracket 31 and the pinching-lever 25 is released. The operator then moves the line to the left by means of the lever 33 into the yoke 32. Upon the return of the resistant to the right, the lever 37 is re-set by a projection 147, and the lever 33 is moved back to the position shown in Fig. 1<a> either by hand or by automatic means. The yoke 32, which supports the line in front of the mould, is suspended from a rope 99 passing over two pairs of pulleys one pair of which is carried by a lever controlled by a cam. The yoke is supported in position to receive the line by a latch 48 which is tripped by the transferring-lever 33 at the end of its movement to the left, whereupon the yoke falls to a position in front of the mould. Casting, trimming, and ejecting mechanism. The mould 82 slides from casting to ejecting position and back again upon a rail 84 which rocks about a vertical pin 84<a>. The melting-pot is moved to and from the mould by a cam, and is provided with a piston which is raised by a cam and depressed by a spring. The mould is reciprocated by a lever and a cam 78, which also serve to withdraw the mould frum the matrices by rocking the slide 84 about its pivot. The foot of the slug is trimmed by a fixed knife during the movement of the mould into ejecting-position. The slug is partly ejected and the mould moves back towards the casting- position, during which movement the " burrs" are removed by a pair of fixed knives. The mould then returns to ejecting-position and the slug is completely ejected. The shaft 71, which drives the casting and ejecting mechanism, is set in motion by the descent of the yoke as in known machines. The shaft is driven by gears 55, 56 from a shaft 61 on which is a loose driving-pulley 68. The inside of the rim of the pulley is engaged by a radiallysliding friction clutch-member 69 which rotates with the shaft. The clutch-member is moved outwards against the pull of a. spring 70 by a lever 64 which is rocked by a weighted lever 60. The lever 60 is supported by a rod 57 pivoted to a lever 54, one end of which rests on a lug on the gear 55. The descent of the yoke withdraws the lever 54 and operates the clutch, which is disengaged again after one revolution of the shaft 71. Distributing-mechanism: The line of matrices is raised by the yoke to the level of the distributor and is pushed on to a pair of rails 117, Fig. 18, by a spring-actuated pusher controlled by a lever and cam. The matrices are lifted one by one by a reciprocating lifter 116, and are pushed over shoulders 114, 115 by a reciprocating plate 124 into engagement with the usual feeding-screws. The space-bars fall into guides 128 in known manner. Beneath the feeding-screws is a longitudinally movable plate 129, Fig. 2, provided with guide-ribs 133. Should a matrix become wedged between two ribs 133, it is carried on by the feeding-screws, the plate 129 is moved, and the frictionally - driven feeding - screws are arrested by mechanism connected with the plate.
