[Class 100 (iii).] Galley mechanism.-A galley mechanism for typographical line-casting machines comprises a chute through which cast slugs are delivered to a slug carrier formed with a plurality of containers each adapted to accommodate one slug, and having means adapted to move the carrier to bring the containers successively into register with the delivery end of the chute. The mechanism relates more particularly to T-shaped slugs which are supported in the galley on the vertical web of the T with their type characters on the horizontal web uppermost, and the chute is provided with guide rails forming a channel to guide the vertical webs of the slugs, these rails being brought into register with the side walls of the successive containers. The usual galley shelf 3, Fig. 2, is formed with an extension 5 on which is mounted the slug carrier, in the form of a chain conveyor, each link 6 of which is open at its rear end and closed at its front end by a plate 7. Each link is formed on its underside with a recess 9 engaged by spring-pressed detents 12 and the movement of successive links to the slugreceiving position is effected by a reciprocating block 14 which carries a spring latch 15, having two spring-pressed projections 15a which engage the groove 9 in the link 6 immediately to the right of that engaged by the detents 12. The block 14 is reciprocated through the link 17 and rocking shaft 18 by a cam 24 on the first elevator 2 or other suitable member operated in the intervals between the delivery of successive slugs, so that on the descent of the first elevator, after a slug has been delivered to that link 6 which is then opposite the chute, the carrier is fed leftward to bring the next link into slugreceiving position, where it is retained by the spring detents 12, the latch 15 being returned to its normal position on the ascent of the first elevator by a spring 23. The detents 12 and latch members 15a are bevelled to permit these movements, and when the carrier is full it may be removed by handles 8, and an empty carrier substituted therefor. In the modification shown in Fig. 6, the slug carrier is in the form of a disc 30, rotatable in the plane of the inclined floor of the delivery chute 27, and formed with radial or tangential channels 31 within which the vertical webs of the slugs are received. The disc 30 is supported on a platform, attached to the vice frame and having an upstanding rim 34 with a gap 35 in line with the chute 27, and the disc is attached to a spindle 36 which carries at its lower end a ratchet wheel 39. The latter is rotated step-by-step as before from the first elevator through a pawl 48 carried by a pivoted arm 46 connected through linkage to an arm 41 which carries a roller 42 adapted to be engaged by a cam on the elevator.
