Abstract: 22,994. Boult, A. J., [Bellows, B. F.]. Oct. 25. Linotype and like machines.-Relates to matrixdistributing mechanism of the kind described in Specification No. 18,033, A.D. 1897, in which there is a system of distributing-channels forking successivelyfrom a single channel or throat and controlled by switches. Fig. 6 represents a front elevation of the mechanism, Fig. 9 a sectional plan, Fig. 3 a rear elevation showing the switch mechanism, and Fig. 10 the type of matrix. The line of matrices 1, Fig. 6, is advanced on the distributing-rail 3, immediately on the return of the transfer slide 64, by means of a spring-actuated presser-bar 91 on a slide 87, which may be actuated by the weight of a vertical rack-bar engaging a pinion meshing with teeth 88 on the slide 87. The switches 9 are mounted on rock-shafts 12, Fig. 3, provided at one end with a crank-arm 13 and crank-pin 14, and are arranged and connected in rows or groups. The top switch is directly connected to a link 19 by its crank-pin 14. The crank-arms of the two switches in the next row are connected by a bar 18, and another link 19 is connected to a crank-pin on one of the arms. The other rows of switches are operated by engagement of the crank-pins in notches in swinging frames 16 actuated by rockers 40 and links 19. The links 19 are connected with armature frames of pairs of electromagnets 25, 26. Each matrix, Fig. 10, is a metal block having a character recess 45 on one vertical edge, a vertical groove 43 in one side, and two vertical rows of selective holes 49 and opposite contact-surfaces 51 in the groove 43. The groove 43 is of such depth that the grooved portions of all the matrices are of the same thickness. A guide-rib 50, Fig. 6, fits in the groove 43. The matrix is forced down by the transfer slide 64 into a vertical recess 62, Figs. 6 and 9, in a horizontally-reciprocating slide 60 on a transfer rail 66. In the end of the slide 60 are holes corresponding in alignment to the matrix holes and also to horizontal rods 54, 55 movable endwise in a fixed block 53. Each pair of rods 54, 55 is associated with a metal rocker 70 and a switch arm 71, and each rocker 70 with its switch arm 71 is associated with contact-devices 75, 76 and determines the energizing of one pair of electromagnets. When the slide 60 carrying a matrix is advanced, the rods 54, 55 are correspondingly displaced by means of the contact-surfaces 51, Fig. 10, and holes 49. Then the slide 60 is returned snfficiently to free the matrix and to bring it over the throat 5, a slide 56 is actuated to eject the matrix, and the slide 60 is completely returned. The switches in the distributing-channels do not return to an initial position after each matrix has passed, but remain in position until reversed by the action of another matrix. The slide 60 is actuated by levers 57, 58 and cams 77, 78 on a shaft 88. The slide 64 is linked to a lever 59 and is lifted against the downward action of a spring 81 by a cam 79 on the shaft 88. The slide 56 is engaged by a lever 83 bearing on a cam 84 on the shaft 88 and attached to a compression spring 82, whereby a quick downward impulse is obtained.
