Abstract: 24,777. Terrell, E. Nov. 8. Type, setting; type; rotary machines.-In a type-setting m a c h i n e, L-shaped types are discharged from a magazine on to a rotating table which moves them to an assembling-device, where they are retained until a line has been assembled, means being provided for transferring the line to a carrier-ring adapted to be used on a printing- machine. Fig. 1 shows a top view of the machine, Fig. 4 a section through the magazine, Fig. 6 a section on the line A-A looking upwards, Fig. 11 a section of the assembling-device, F i g. 7 a perspective view of one of the types, Fig. 10 a diagram showing the path of one of the types from the magazine to the table, and Fig. 15 a vertical section of one of the carrier-rings. The magazine 2 consists of rectangular tubes 15 secured between rings 11, 13, and arranged over an annular table 19 formed on a ring 10, which is secured by brackets 12 to the ring 11 and is supported by arms 9. Types 16 of L-sbape are piled in the tubes 15 and rest on the table 19. Cylinders 21, one for each tube 15, are connected by tubes 23 to a keyboard 3 and are each provided with a piston 22 having a rod 25. When a key is operated, the corresponding type is pushed from the tube and falls on to a rotating table 8 carried by a shaft 5. The ring 11 is formed with a groove eccentric to the rounded edge of the table 19, and the ends of the rods 25 are bevelled so that the long leg of the type is pushed into the space between the table 19 and the ring 11, and the type then moves through the positions shown in Fig. 10 and falls on the table 8 with the type surface in contact with the table. The types revolve with the table and fly outwards by centrifugal force until their short legs engage a circular guide shoulder 36 by which they are guided into a spiral groove 37, wherein the types move until they enter a spiral groove 39 in the assembling-device 4. The groove 39 is formed in the underside of a fixed plate 54 arranged over a disk 42, which is supported by spring bolts 44 on a table 40 mounted on a vertical shaft 41, a forked lever 45 being provided whereby the table may be raised. The type are discharged from the groove 37 with sufficient velocity to carry them round the groove 39. Stops 56 are provided any one of which may be pushed out to arrest the first type discharged. In some cases an impelling-device, consisting of a toothed disk 63 mounted on a shaft 60 driven by a worm gearing 62, may be provided to drive forward the type as they leave the groove 37. The table 40 is adapted to be rotated when in a raised position, and for this purpose is provided with round-ended pins or studs 47 which, when the table is raised, engage teeth on a wheel 48 mounted on a shaft 49 having a crank 50. The shafts 41, 49 do not intersect. When a sufficient number of types have accumulated, the operation of the keyboard is discontinued, and the table 40 is raised and then rotated so as to carry the types to the bevelled discharge opening 55 of the plate 54 which is open in one quadrant. As the types emerge, their short legs are pressed by the spring plate 42 into the jaw of a carrier ring 52 mounted on the hub 51 of the shaft 49. The carrier ring consists of a rigid plate 52 and a flexible plate 57 having a slight space 58 between. When the carrier-ring is slipped on to the hub 51, the space 58 comes over the discharge passage 55 of the groove 39 so that the short legs are forced into the space and the long legs lie on the ring with the type surfaces exposed. When all the type have entered the ring, it is removed and replaced by another. The carrierrings so filled with type are assembled on the mandrel of a suitable printing-press.
