Abstract: 6927. Savarese, A., and Chateau, J. D. March 30. Type, setting.-Relates to a composing-machine manipulated from a keyboard, the types &c. piled in a magazine sliding according to the principle described in Specification No. 10,349, A.D. 1894, but along a series of rules spaced round an inclined rotary cylinder, or on an advancing carriage or an endless band &c., all of which move intermittently, instead of along a single rule. The magazine is composed of bars 1 of U-section, forming a series of channels closed by a plate 2, which may be partly of glass ; or these tubes may be replaced by rails. When a key of the keyboard b is pressed, a type falls on the particular spring plate or rule x of the cylinder c w h i c h happens to be opposite all the openings of the magazine. The arrangement for releasing the type consists of levers 3 having teeth &c. 4, 5 and connected by shafts 6 to plates 7 arranged in pairs with lateral forks 8 opposite one another. This grouping allows the depression of one key to release either a small or a capital letter &c. The draw-wires 12, w h i c h operate on the forks 8, are preferably made in two parts fastened by ring nuts &c. 18, and are connected to a plate fixed at an angle to the typelever of the key 15. The plates 7 and the draw-wires 12 are fitted with recall springs 10, 16 respectively. When the escapement lever is operated, the tooth 4 engages in the slot of the last type but one, and the tooth 5 releases the last type, the return oscillation of the lever releasing the tooth 4 and engaging the tooth 5. In the modification shown in Fig. 17, for use with rails, the lever 3 terminates in a foot 2 provided with a portion of a rail 7, a shoulder and projection 4 forming one escapement hook, and a shoulder on the rail 1 forming the other hook. The recall spring 16 is attached to any angle piece 17 supported on arms 19 jointed to the frame a of the machine. A lug 21 on the bar 17 is connected by a wire 22 to one arm of a bell-crank lever 23, the other arm of which is attached to a draw-wire 25 connected to a special key 26. This bar 17 is provided with a recall spring 27, and can move between adjustable stops 20, the extreme positions allowing engagement of the fork 8 for the small or capital letters respectively. The type levers of the keys 15 are kept apart by pegs on cross-pieces, and are pivoted on a common axis and rest freely on a cross-piece 31, supported by rods 32 jointed on the axis of the levers and connected by wires 33 to arms 34 on an axis 35. One of the arms 34 is connected by a wire 37 to a lever 38 integral with a shaft u, which carries a known form of double pawl escapement v, engaging a ratchet-tooth crown-wheel on the bottom of the cylinder c, and allowing rotation of the cylinder through a rule space at each depression of a key. Another pawl and ratchet-wheel at the bottom of the cylinder prevent backward motion. Motion is communicated to the cylinder c through the pinion i from a bevel-wheel j on a shaft k geared to a drum supporting a falling weight l &c. When the cylinder rotates, the type last received is released and slides down its rule to a screen h, faced with lead to prevent rebound. This screen extends across the space between the magazine and a fixed rule X, which collects the type for the lines. Intermediate screens may be placed along the cylinder to make the descent of the type gradual. The first type on the rule X is a special " line- " cutter " type 69 having a corresponding key 29. Horns on this type engage a hook 47 on a lever 46. The length of the line of type is determined by the position of an index finger 60 on a shaft 58, pegs spaced variably on a lantern-wheel 61 on the shaft k intermittently raising the finger 60 and operating the hook 47 so that the types slide past it to a second hook 48. When the finger 60 falls back, the hook 48 is operated, and the types, divided into lines, are led on to rails 77 on a carriage 71, which advances through a rail space at each movement of the lever 46 under the action of a counterweight 81, a double pawl escapement 80, and a rack. The second movement of the lever 46 also moves a bell-crank lever 51, and a rod 64, causing a hammer to strike a gong 67 and give the signal for another line-cutter' type. Separate keys may operate the small and capital letters, and certain magazines may contain multiple-letter types. The magazines may be refilled at their top ends from tubes carried in a framework and advanced intermittently.
