Abstract: 6617. Dacheux, R. March 16. Setting type; keyboards. - (1) The type channels 25, Fig. 1, receive types from the distributing-apparatus -shown above and to the left. This distributing-apparatus is of the kind described in Specification 3325/10. A longitudinally movable rail 22 is provided in each channel, the rounded lower end 23 of the rail effecting the erection of the types sliding down it, as shown in Fig. 9. To lock the various type channels to the framework of the machine, each channel is provided with heels or dovetailed pieces 38, which engage mortises 41, 42, 43 in the framework 4. A spring-controlled bar 39, extending the whole breadth of the magazine, and pressed by a cam 40, forces all the heel-pieces 38 against a fixed bar 44. The lowermost type escapes between two inclined lugs 45, 46, Figs. 6 and 7, when pushed into a slanting position by a spring-controlled ejectorfinger 50. An ejector finger is provided for each channel, the spindles 55, Fig. 1, carrying the fingers being all mounted in a rigid frame which is adjustable by screws and milled heads 61 to withdraw all the fingers from the openings of the magazine. The key-levers 76 are connected up to the ejector fingers by bell-crank levers 73 and horizontal connecting-links. (2) The types fall from the magazine on to a belt or apron 90, and are guided to an assembly point by converging side belts, which travel at a greater speed to secure equal time of descent. To prevent the types from turning over when dropping on to the collector belt 90, a transverse bar 112 with an inclined face 114, Fig. 13, is provided so that, as the type escapes, its upper part contacts with this inclined face while its lower part contacts with the belt. (3) An indented wheel 115, Fig. 14, receives the types sliding down the channel 101 from the collector belt 90, and delivers them in an upright position to the composing-stick 116. The wheel 115 is split perpendicularly to its axis so as to admit therethrough a thin strip forming an extension of the composing-stick. The latter is provided with a side recess containing a number of blade springs to press against the sides of the types. Justifying type. - Compressible spaces are used such as those described in Specification 23,808/08. When a sufficient length of line has been formed, a line-separating needle 126 is adapted, by the operation of a key 131, to drop into the composing-stick behind the type last set. The needle is carried by a sliding piece 125 which is operated by an arm from a one-revolution cam-shaft released after a few types have been assembled behind the separating-needle. This movement carries the line of types up to a counter slide 144 acted on by a lever 146 operated from the cam - shaft to compress the spaces in the line to the proper size for justification. An abutment bolt 142 is inserted behind the needle to support it against the pressure. To gauge the length of the composed line, a fixed index finger 121 and a movable one 154 are provided. The movable one is connected with a rack 156 fed forward, by a pawl 162 connected with the space key 157, to the extent of the compressibility of a space. The rack is returned to its initial position by a spring 170, whereupon a retaining-pawl 166 is released by the line-limiting key 131. The onerevolution cam shaft is started by a stud 129" on the needle-piece 126 acting on a bell-crank lever 138, 140 to unlatch an arm 141 connecting up the clutch-engaging device of the cam shaft. The needle is raised clear of the types by travelling up a switch-piece 161 in the backward movement of the slide 125. This slide is operated by a cam-operated lever provided with two lugs each engaging in turn a stud on the slide and spaced apart so as to allow the needle slide to be moved by the pressure of the few types introduced to begin the next line as above referred to. Galley mechanism. - The justified line is pushed sideways into a galley, a gate forming an extension of the composing-stick being raised and lowered for the passage of the line. Driving-mechanism. - The cam-shaft 181 is operated by worm gearing 179 through a onerevolution clutch, the movable member 183, Figs. 20 and 21, of which is spring-controlled, and is released to engage the other clutch member 182 when a catch 188 is disengaged from the part 187 by the dropping of a lever 189 connected with the arm 141, Fig. 14. The clutch is opened after one revolution by a rocking arm 197 acting on a projection 195 on a pivoted piece 192, Fig. 23, carried by the clutch member 183. To allow the re-engagement of the clutch members, the pivoted piece 192 is moved out of the way by a cam-actuated lever 181.
