Abstract: 18,383. Bellows, B. F. Aug. 16, 1906, [date applied for under Patents Act, 1901]. Linotype and like machines.-Relates to (1) mould mechanism, (2) trimming - mechanism, (3) ejecting - mechanism and means for delivering the linotypes into a galley or other receptacle, and (4) means for wiping the mould, trimming - knives, and metal-pot nozzle. (1) The mould block 1, Fig. 7, is detachably secured in a slide 3 by means of spring - projected tapered pins 50, Fig. 4, entering tapered holes in opposite ends of the block. Means such as a rocker 52 may be provided for retracting the pins 50 simultaneously. The slide 3 is reciprocated in ways 11, 12 in a frame 10 by connexion 61 with an arm 60 on a rock-shaft 62, which is actuated from a cam 69 on a shaft 68 to more the slide to ejecting position, and by means of a spring to move the slide to casting position, determined by a stop 18 on the frame 10. The frame 10 may be provided with passages 13, 14 for circulation of cold water. The matrix line 5 and the metal-pot nozzle 6 are moved against the mould by mechanism such as that described in Specification No. 21,467,- A.D. 1904. (2) The linotype is trimmed on the foot by a knife 100, Fig. 4, as the mould moves to ejecting position, and on the sides by knives 20, 21, Fig. 7, during ejection. The knives 20,21 are adjustably mounted in a frame 30, Figs. 5 and 7, removably secured on the frame 10. The frame 30 is formed with inclines 31, 32, 33, 34 for engagement with inclines 22, 23, 24, 25 (which may be the ends of adjustable screws 28) on the knives 20, 21, and adjustment is effected by means of a set-screw 37 bearing against one end of both knives and provided with a gauge 67. The knives are pressed apart by springs 9. The inclines 33, 34 are made steeper than the inclines 31, 32 so that the upper knife has a greater movement corresponding to the different positions of the slots in the different mould blocks. The knives are retained in the frame 30 by plates 38, 39. (3) The ejector 75, Figs. 4 and 7, is clamped to a slide 77 supported on guide-rails 19 and, preferably, additionally guided by means of a depending arm 78 sliding on a shaft 79. The ejected linotype is received in a transferring-device 80 which is rotated to deliver the linotype. The device 80 is provided with a slot 81, the front wall of which is rounded off as shown in Fig. 7, and the linotype is first ejected across the top of the slot 81 and then tilts down into the slot when the ejector is withdrawn. The bottom of the slot 81 is inclined for discharge of the linotype by gravity, but the linotype is held in the slot by a pivoted spring catch 8 until the latter is released during the rotation of the device 80 by striking a fixed pin 90. The device 80 is carried by a sleeve 84 on a verticallymovable shaft 93 shifted by means of a cam 96 on the shaft 68, and this shifting of the shaft 93 effects rotation of the sleeve 84 by means of a pin 91 and spiral groove 85. (4) Two mould wipers 40, 45, Fig. 4, are pivoted on the frames 10, 30, and wipers 70, 97, respectively for the trimming-knives and metal pot nozzle, are pivoted on the slide 3. Each wiper is provided with a spring-actuated friction pin engaging against the slide 3 or the frame 10 so that the wiper is moved to and from the part to be wiped during the movement of the slide 3.
