Abstract: 134,836. Macomic, C. A. Nov. 2, 1918, [Convention date]. Setting and distributing type; keyboards; prooftaking apparatus. - A machine for setting type, dies, &c. into line-holders to form an entire page or column of matter, which may be used for printing or for making a matrix and is subsequently distributed by a single operation, comprises two alined stacks 5, 6, Fig. 5, of typesupporting plates or the like, one pair of alined plates being provided for each line of matter. The plates are preferably grooved or slotted to support the type, and each groove in the plates of the stack 5 contains a complete fount of type. Type-holders, each adapted to contain a line of type, are located between the stacks of plates, and the founts of type are pushed by the action of keys through varying distances from the plates 5 into the plates 6; so that the required types come to rest in the type-holders. Typewriting mechanism is provided for making a proof of the composed matter. Type-holders of the form shown in Fig. 16 are placed one above another in a slot 8 between the plates 5, 6 with their ends resting in vertical slots in guide-plates. The stack 6 is movable towards the stack 5 by means of a screwed rod 15 and crank-handle 14 to cause alining-pins on the plates to enter holes 12 in the type-holders. Pins 30 are passed through the holders and through holes in the types to secure the types to the holders, the pins being advanced and retracted by a hand-operated slide. When loaded, the type-holders are raised by a pusher 47 into a pivoted guide-member 45 and delivered to a printing-drum 46. The holders are received in the part 54 of the drum and are held against displacement by a sector 55, which remains stationary while the drum receives a step-by-step motion. The type-setting mechanism consists of differentially adjustable racks or pushers 68, Fig. 6, equal in number to the grooves in a magazine plate 5 and operated by toothed dogs 69 which are controlled by the typewriter keys. The key-levers 88, Fig. 4, impart varying degrees of motion to a yoke 84 connected by arms 85 to an horizontally sliding frame 79, which is thereby retracted against the action of a coil spring into contact with stop-pins 75, which are interposed in its path by the keys. A driver 89, Fig. 6, sliding on a rod 90 carried by the frame 79, positions the dogs 69, and is traversed along the rod 90 by the typewriter escapement-mechanism so as to engage the dogs in succession. To effect the selection of capital letters, an increased movement is given to the driver 89 by the action of a shift-key. After all the dogs have been set, they are moved rearwardly to operate the pushers 68 and position the type, by a frame 110 having handles at each end to be grasped by the operator. After a line has been composed, the setting- mechanism is lowered a step equal to the distance between the magazine plates 5 by means of screwed rods and a crank-handle into position for composing the next line. The filled type-holders may be set in the printing-drum or utilized for casting a duplicate forme for printing the column or page. After the types have been used, the holders are restored to their original positions between the plates 5, 6, and the types are pushed back from the plates 6 and the holders into the plates 5 by a series of comb-plates 61, Fig. 5, operated by a screw 65 and crank-handle 66.
