Abstract: 479,801. Type-making machines. KINGSBURY ENGINEERING CO., Ltd., MYERS, S., and CAMP, A. F. March 2, 1937, No. 6244. [Class 100 (iii)] Galleys and galley-mechanism.-In typecasting machines which are adapted to produce in succession a number of characters of like kind, means are provided for delivering each set of like characters to an appropriate compartment of a compositor's tray. (1) Means, such as an auxiliary line-hook, are provided for shifting a set of characters assembled in the line-channel clear of the channel. The straight line-channel, formed by ribs 22, Fig. 1, into which the cast type are normally drawn by the line-hook 24, has a curved extension 34, formed between a curved guide 32 and a plate 33. The types are drawn into this channel by the line-hook 24, and are removed therefrom by an auxiliary hook 30, so as to fall through an opening 43 into deliveryshoot 45. The hook 30 is moved in an arcuate path by an arm 26 on a shaft 25, which is operated by pneumatic means brought into action by a cam. The normal line-hook may be modified, so as to effect this movement of the type. (2) A carriage for a compositor's tray is moved each time that the matrix of the casting-machine is changed, to bring a corresponding compartment of the tray into register with the lower end of the shoot 45. The tray is supported on a carriage 55, Fig. 4, which rests on a frame 53, which, in turn, rests on a second frame 54, the frames being movable step by step in directions at rightangles to one another. The frame 53 is moved forwards or backwards, as required, by two pairs of pneumatic cylinders 56, one pair on each side, and the frame 54 is moved by a single pair of cylinders 57. The piston of each cylinder 56 acts on a bell-crank lever 64, Fig. 5, the free end of which is thereby moved into engagement with a rack 58 on the frame 53. The lever 64 is pivoted on a block 67, which can slide between abutments 68, 69. Further movement of the piston moves the block 67, and also the frame, through the distance permitted by the abutment 69. The rack 58 is normally engaged by a locking- plunger 59, which is withdrawn, to permit movement of the frame, by one or other of two levers 70, which can be rocked by pneumatic cylinders 74. Movement of a lever 70 to withdraw the locking-plunger opens a valve 76, by which compressed air is admitted to one or other of the cylinders 56, according to the direction of movement required. The frame 54 is moved by similar means. The operation of the mechanism is effected by the existing automatic control of the machine, which may be in the form of a perforated record-strip. Certain of the air-pipes, the admission of air to which is controlled by the record-strip, have branches leading to a valve-chest, the valves within which are operated by appropriate signals in the recordstrip, and serve to admit air to the cylinders that withdraw the locking-plungers of the frames 53, 54. (3) Instead of the compositor's tray being movable, an outlet for the type may be moved over the tray by similar mechanism, or the type may be fed to a branched delivery-shoot 129, Fig. 13, the branches of which are controlled by pivoted shutters 133. The automatic control means effects the operation of the shutters and also a pivotal movement of the shoot to bring the outlets over different rows of compartments of the tray 132. The shoot terminates some distance above the tray to provide clearance for the usual upstanding wall 154, Fig. 15 of the tray, and the gap is filled by a partitioned frame 155, which rests on top of the tray. Some of the partitions of the frame extend to the bottom of the tray to divide the compartments temporarily into smaller compartments.
