Abstract: 127,442. Imray, O., (Intertype Corporation). July 10, 1918. Type-bar-making machines. - The machine is equipped with a number of interchangeable magazine-units, provided with one, two, three, or more magazines respectively, and means are provided for readily adjusting, from the front of the machine, the mould, ejector, trimming knives, and fount-distinguisher for change of fount. Magazines.-(1) The magazine units are each provided with a base a<2>, Fig. 5<a>, or a<3>, Fig. 6, which is detachably pivoted on lugs X on the main frame 7 and is tilted into a position at the rear of the machine for removal of a magazine. The positions are determined by the engagement of projections d<2>, c<2> or d<3>, c<3> on the bases with parts 8, 9 of the frame. The pivots consist of pins x which are passed through the lugs X. The bases a<2>, a<3> support two and three or more magazines M respectively, and a base supporting only one magazine is also provided. The base a<2> is provided with the following quick-change mechanism. A frame 28 supporting the two magazines M is carried at each side by bell-cranks 30, 31 secured to rock-shafts 29 on the base. The bellcranks are connected by a link 34 and are pivoted to the frame 28 at 32, 33. On rocking a handlever 35 on the bell-crank 30, the frame is raised and lowered in an arcuate path to the front or rear, and the bottom or top magazine is brought into register with the escapement reeds 3 and the assembler entrance. The base a<3> is provided with the following quick-change mechanism. A frame 36 supporting the three or more magazines M is provided at the front and rear with shafts 37 carried by cranks 38 on stub-shafts 39 which are connected by links 44 and pass through slots 41 in the base a'. The shafts 39 are provided with hubs 40 fitting the slots, and with pinions engaging racks 43 at the sides of the slots. On operating a hand-lever 45 on one of the shafts 39, the frame 36 is raised and lowered successively in a series of arcuate paths. (2) The magazine entrance 6, Fig. 11, is mounted on rocking arms 12 and can be moved backward by means of a hand-lever connected to a link 10. To render the entrance self-adjustable to the operative magazine, the entrance is secured to a frame 16 which is pivoted at 15 to the arms 12; further, the entrance is provided with fingers 6<c> for resting en the top of the magazine. (3) The magazines are each provided with a shutter m<1>, Fig. 11, for closing the rear end. The shutters are mounted on the magazines by spring blades m<3> operated by levers m<2>, which are pivoted to the magazines and are formed with projections m<4> for engaging stationary cams 7a. When any magazine is moved out of the operative position, the levers m<2> permit the springs m<3> to close the associated shutter. Escapements.-The escapements m, Fig. 9, consist of arcuate members 20 which are mounted in grooves in the magazine and are moved in one direction by the reeds 3 and returned by springs 21. To compensate for irregular fitting of the escapements, each reed is formed with an upper part 25 which is yieldingly connected by a spring 27 to the lower part 26. Distributing matrices.-The fount-distinguishing device is arranged at the entrance of the distributor box, and is adjusted by a handle which can be readily reached from the front of the machine. The handle passes through a slot in an index plate. Moulds.-The mould-wheel, Fig. 13, carries a number of moulds having different slot-dimensions, and is rotated manually to bring the selected mould into position. The moulds each consists of a body 48, liners 48<a>, and a cap 49, the body fitting between blocks 47 and having ears 50 which rest on the blocks. The liners and the cap are detachably secured by pivoted bolts 48<a> which enter slots. One of the moulds is adapted to cast slugs having overhanging types, by providing a cap 49a having a number of recesses 54 which receive the overhanging parts and are separated by grooves 53 for forming ribs on the type-bar. Ejecting type-bars.-Mechanism similar to that described in Specification 28386/13 is provided for bringing one of a set of ejector blades 70, Fig. 14<a>, of different widths into engagement with the ejector slide 74. The blades are mounted in a case 67 which is shifted laterally by a hand-lever 66 connected by a rod 65 to slides 61 having oblique ribs 69 which engage ribs at the top and bottom of the case. The selected blade is engaged by a T-projection on the slide 74 and is then moved forward by the slide, a T-projection 72 on cross-bar 71 holding back the other blades. An interlccking-device is provided for preventing the case 67 from being shifted before the slide 74 is withdrawn. The device consists of a handlever carrying pawls adapted to engage alternately with teeth on the rod 65 and a notch in the slide 74 respectively. Trimming type-bars. - The movable knife 85, Fig. 15, is adjusted by turning a threaded sleeve 92 provided with an ,annular dial 94 having graduated grooves 95 which engage a detent. The sleeve 92 is threaded into a ring 93 on the vice frame and is rotatable on a thimble 89 formed on a slide 88 which carries the knife, the face 92a of the sleeve engaging the slide. A spring 90 is arranged between the end of the sleeve and a stationary plate 91.
