[Class 100 (iii).] Cleaning matrices.-In apparatus for cleaning matrices by means of rotary brushes supplied with benzine &c., the matrices are fed past the brushes by parallel feedscrews, are reversed during their travel, and are then led between travelling drying- bands to an assembler. The matrices are contained in a magazine 6, Fig. 5, having a vertical ribbed guide-member 7 to fit the V-shaped notches, and are ejected one by one by a pawl 12 operated by a reciprocating slide 14. The pawl is pivoted to the slide, and is guided by surfaces 17, so as to engage only the lowest matrix. A detent 8 holds back the upper matrices. The matrices are ejected on to a guideway 39, on which they are held down by a pivoted member 29. The matrices are fed along the guideway by a pair of screws 31, which engage their ears, and their faces are cleaned by rotary brushes 47, 48. The matrices are reversed during their travel by a pivoted hookmember 44, which engages their leading ends. The edges of the matrices are cleaned by rotary brushes as they descend in the magazine. The matrices are dried by endless bands 55, 56, Fig. 7, to which they are delivered by a shoot 45, the bands being driven at different speeds, to give a rubbing action. The bands are pressed against a supporting surface 57 by a spring-pressed plate 58, which may have an electric heating-element. The cleaned matrices are delivered into an assembler 65, which has a number of compartments, and is supported on inclined rails 72. The matrices are pushed into the compartment in use by a star-wheel 64, and are supported by a sliding follower 67, which, when the compartment is full, trips a catch 69 and causes the assembler to descend a step.
