Abstract: 11,285. M³llendorff, E. June 21. Type, setting &c. ; linotype and like machines.- Relates to the justification of lines of type or matrices. Fig. 4 shows, in part sectional elevation, a machine for justifying lines of type 1 having separators 2 between the words, Fig. 6, a transverse section and Fig. 2 an arrangement of contacts for selecting spaces. The line of types 1 is placed in a carriage 3 between a stop 4 and a piece 5 sliding in the carriage 3 and drawn by a spring 7 so as to press the line against the stop 4. The sliding piece 5 carries a pin 9, which moves over contacts or steps &c. on a plate 12 carried by the carriage 3. The position of this pin 9 is determined by the length of the line, and a space is selected in accordance with the contact or step &c. on the plate 12 with which the pin 9 contacts or engages. Fig. 2 shows an arrangement of electric contacts in which the outer ones b, g represent and operate to select the largest and smallest space for insertion in the line in place of the separators 2, and the narrow parts of the contacts c, d, e, f operate to select spaces of different sizes between the smallest and largest space. In the arrangement shown in Fig. 4, the plate 12 is provided with a series of steps a<1>, b<1>, c<1>, d<1>, e<1>, f <1>, g<1>, h<1> with which the pin 9 operates mechanically to select the spaces, the steps corresponding with the spaces in the cases or reservoirs a", b<11>, c<11> &c., Fig. 6. The slide 5 moves the pin 9 over contact-pieces, Fig. 2, or over the series of steps, Fig. 4, and, as the spaces are successively substituted for the separators 2, the line is re-measured. The steps in Fig. 4 are shown of inclined or triangular form, and the plate 12 is movable vertically into different positions according to the number of separators in the line, so that the pin 9 operates with the wider parts of the steps as the number of separators in the line increases. The plate 12 is moved downwardly by gearing operated by a star-wheel 66 engaged by the separators 2 when the carrier 3 is moved to the left, Fig. 4. On the pin 9, which is mounted to slide towards and from the plate 12, is a lateral pin engaging a slotted arm 20 on a shaft 24 journalled on an extension 23 of the slide piece 5. An arm 25 on the shaft 24 engages a rod 26 throughout the justifying movement of the carriage 3, which may be effected by a cord and weight &c. The rod 26 is carried by arms 28 of a rock shaft 29, having an arm 30 bearing against a cam 31 on an intermittently-rotating shaft 32. On the shaft 29 is an arm 33 pivoted to a rod 34, connected at its other end by a rod 35 to an arm of a lever 37, 38 pivoted at 36 and bearing against a cam 39 on the shaft 32. The rods 34, 35 carry an ejecting-pin 41 by which the space is ejected from the appropriate channel and falls down the guide 42 on to a space lifter 43. As the carriage 3 moves to the left, the first separator engages the end of a bar 55, which it moves endways and operates a ratchet clutch by which the shaft 32 is driven through one revolution, and the cams 31, 39 permit the ejector pin 41 to move over the proper channel and eject the space therefrom. A semicircular disc 62, of wedge form, ejects the separator 2 from the line, and opens it out to receive the space which is moved up into the line by the lifter 43 after the wedge 62 has passed through it. The disc 62 is on a shaft driven by the clutch wheel which drives the shaft 32. The lifter 43 is pivoted at 36, and is controlled by an arm 44 and cam 45. The operation is repeated as each separator 2 in the line contacts with the clutch-operating bar 55, the line being thus re-measured by the pin 9 after each insertion of a space, and the pin 41 moved by the arm 33 &c. over the corresponding space channel. Other arrangements of stepped selecting and contact devices are described, a pivoted plate or cylinder being substituted for the sliding plate 12. Arrangements are also described by which the movement of the pin 9 is increased by gearing &c. connecting it with the slide 5, and the widths of the selecting-steps are correspondingly increased.
