Abstract: 437,879. Type - making machines. SCHNEIDER, J., 8a, Briennerstrasse, Munich, Germany. May 23, 1935, No. 15087. [Class 100 (iii)] Single-type composing and casting machines; moulds.-In a machine for casting justified lines of type, which is operated directly by means of keys without preliminary representation of the line or the use of dummies, the successive words constituting the line are retained separate, and spaces which will justify the line are cast subsequently, and are placed one at the end of each word, the words being then transferred one after another to a galley to form a complete line. An axially adjustable matrix-wheel 2, Fig. 1, bearing two rows of radially slidable matrices is continually rotated through a friction device, and is arrested with the required matrix over the mould by the depression of one of a series of keys 43 which raise stops 41 into the path of an arm 40 on a shaft 39 which is geared to the matrix - wheel shaft 1. The mould-cavity 10, Fig. 1<a>, is bounded by four walls 22, 23, 24, 25. The walls 23, 24 are fixed, and the wall 25 is movable by means of a rod 30, in order to adjust the mould to the size of type to be cast. The wall 22 is movable away from the walls 23, 24, in order to open the mould, and has connected to it a blade 26 which pushes out the cast type. The outward movement of the wall 22 releases an ejector 27, which is driven forwards by a spring to deliver the type into an assembly channel. The arrest of the shaft 39 causes the starting of a cam shaft 62, by which the casting is effected. A cam 71 permits a feeler 9 carried by a slide 32 to be advanced by a spring into engagement with one of a series of notches in a pair of toothed wheels 6, 7 secured to the matrix-wheel, whereby the matrix-wheel is locked in position. The depths of the notches in the wheels 6, 7 are proportional to the sizes of the different characters, and the movement of the feeler 9 is transmitted through the rod 30 to the wall 25 of the mould, which is adjusted accordingly. A cam 64 operates a hammer 68, which depresses the matrix on to the mould, and a cam 69 operates the plunger 72 of the metal-pot. A cam 70 then acts through a lever 73 to open the mould, so that the type is carried away by the ejector 27. Justifying type; galley-mechanism.-(1) The cast type is pushed by the ejector 27 into one of the channels of a slotted drum 14, at the opposite side of which is a bridge 21 leading to a galley 13. The bridge is normally out of alignment with the drum channel, to prevent the type from passing out of the drum. After the types forming a word have been assembled in the drum, it is advanced a step against the action of a spring by depression of a key 17, to bring another channel into position. (2) The return movement of the feeler 9 away from the matrix-wheel is imparted to a spring- tensioned measuring-slide 89, which is prevented by free-wheel rollers from moving in the reverse direction, so that its movement corresponds to the length of the composed line. For each word-space in the line, one of a series of wedges 109 is released by the key 17 that rotates the drum 14, and slides down an inclined rod 115 into contact with the end of the measuring- slide. When the line has been completed, an abutment 104 is raised behind the released wedges by a key 103, and is held by a latch 106. The wedges are then raised by a beam 99 operated by a key 100 until they fill out the space between the measuring-slide and the abutment 104. The rise of the beam 99 is thus proportional to the size of the spaces required to justify the line, and is imparted through inclines 96, 97 and the feeler-slide 32 to the adjustable wall 25 of the mould. (3) After the words of a line have been cast, the type-carrying drum 14 is released by depression of a key 20 and is returned to initial position by its spring. The justifying-spaces are then cast by successive depressions of a blank-matrix key, and are placed one at the end of each word, the drum 14 being stepped on for this purpose by depressions of the key 17. The bridge 21 is moved into alignment with the operative channel of the drum, so that each word is driven by the ejector 27 out of the drum and into the galley 13. The machine may be controlled electrically, pneumatically, or hydraulically, instead of mechanically.
