Abstract: 2897. SavarÞse, A. Feb. 17, 1906, [date applied for under Patents Act, 1901]. Type, setting; type; formes, securing in machines.-Relates to machines of the kind in which the types are bifurcated and slide upon rails or rods. The types are assembled, justified by hand with the aid of a scale, and collected in lines upon supporting- rods which may be secured to the cylinder of a printing-machine. The magazine consists of vertical rails 7, Fig. 1, which are inclined at their lower ends and which engage the slots in the types, Fig. 14. The lowest type is ejected by means of a rocking pusher 15, Fig. 7, and falls on to one of a number of rods 24 arranged radially on an inclined cylinder 25. The type slides down the cylinder, which is then rotated to bring the next rod 24 into position to receive a second type. The pushers 15 are actuated by rods 22, Fig. 3, connected to levers 26 which are urged upwards by springs 31, but are normally held down by latches 33 controlled by key-levers 35. Depression of a key-lever releases the lever 26 which rises and brings an eccentric 29 into contact with a rotating shaft 40. The eccentric is thereby rotated, the lever 26 is depressed, and the pusher is actuated A finger 38 on the keylever prevents more than one revolution of the eccentric. The cylinder 25 is rotated by bevelgearing at its upper end connected with a driving- shaft 5. An endless chain 72 passing over sprocketwheels, one 71 of which is carried by a weighted lever 69, takes up the motion of the driving-shaft when the cylinder 25 is stationary. A worm-wheel on the lower end of the cylinder gears with a wormshaft which is frictionally connected with a constantly-rotating shaft. The rotation of the wormshaft and that of the cylinder is controlled by an escapement comprising a toothed-wheel and fixed and movable pawls carried by a shaft 46, Fig. 3, which is rocked by the key-levers. The cylinder 25 is driven from the shaft 5 through a belt and fast and loose pulleys on an intermediate shaft. The belt is provided with a shifting-lever which is connected with a rod 85, Fig. 1, carrying stops 86, 87. A collar on the lever 69 slides on the rod 85 between the stops and moves the belt on and off the fast pulley. Ratchet-wheels and pawls prevent backward rotation of the cylinder 25. Means are provided for adjusting the angular position of the cylinder with respect to type-pushers 15. On reaching the bottom of the cylinder 25, the types are turned through an angle and pass on to a rail 96. Thence they are delivered to vertical rails 101 which are brought successively in line with the end of the rail 96. They are then transferred to an horizontal rail 107, shown in plan in Fig. 15. The line is measured by a fixed finger 108, carried by a rocking shaft 110, and a movable finger 109 which is connected with a pointer 115 moving over a scale 116. The line is justified by hand, and is pushed on to a supporting-rail 119 having a claw at one end to retain the line. The rails are pressed by a spring plunger 120 against a flange 123. The composed lines are placed upon an inclined plate 121 which is detachably held in position by a spring-pressed flange. The rails bearing the composed types may be placed on the cylinder of a press and secured thereto by suitable means such as a frame 126, Fig. 19, a dovetail piece, or concentric wires or cylinders. The types may be of the form shown in Fig. 14 in which the slot is formed by two planes 128 inclined to one another and united by a circular groove 129.
