Abstract: 7884. Lock, W. H., Holbourns, J. G., and Longhurst, H. A. April 4. Linotype machines ; monotype and like machines. -Relates to means for assembling and distributing reversible matrices in the Mergenthaler machine, (Specification No. 14,582, A.D. 1890), or in a doubleletter machine such as that described in Specification No. 18,886, A.D. 1895, and applicable in a typecasting machine such as that described in Sptcification No. 1903, A.D. 1900, in which the formative cavity is in the face of the matrix instead of in the edge. (1) The matrix 1, Fig. 3, is provided in the foot with a rectangular notch 2 situated to one side of the vertical axis, so that when reversed and normal matrices are juxtaposed, the notches of the two matrices do not register or overlap. This notch serves as the means for separating the reversed matrices from the normal matrices preparatory to distribution. In the case of a matrix such as that described in Specification No, 1903, A.D. 1900, a formative cavity is provided in each face, centrally or non-centrally according to the thickness of the thinnest matrix of the fount, and in addition to the notch in one edge, for adjusting the mould, a similar notch is provided in the other edge. (2) The line of matrices 1, Figs. 1 and 3. is raised in the second elevator 5 above the distributing-mechanism 26 to an upper lift box 13, which is provided with an extra gate 65 in position corresponding to that of the notch 2 of a normal matrix. The corresponding lifter 14 is provided with a projection 15, which engages in the notch 2 of a normal matrix but against the edge of a reversed matrix, so that the latter is lifted into the path of a forked pusher 17 and ejected down inclined rails 34 into a special shoot 35 rifled or otherwise formed to turn the matrices, the normal matrices falling down a shoot 37. The pusher 17 is operated by levers 19, 20 from a cam 23 on the shaft 24 of the distributor screw 25, and the lifter 14 is pivoted to a bell-crank lever 29 pivoted on the frame at 30 and connected to the lever 20 by a flexible arm 32 at 31. In order to prevent the lifting of more than one matrix at a time from the box 13, a spring-projected forked rod 67 with inclined prongs 69 is provided in the path of the lifted mitrices. The shoots 35, 37 both deliver by a common channel 39 to a lower lift-box 16,which is provided with inclined rails 42, 43. the channel 39 may deliver in front of a star-wheel 40. (3) In one arrangement for turning the matrices for assembling, a shoot with a rifled or like channel and a plain channel is arranged between the assembler belt and the assembly box, and is conveniently pivoted on the axis of the ordinary star.wheel, and provided with a handle for adjustment and a catch or detent for retaining it in either of its two positions. In another arrangement, shown in Fig. 6, a short inclined shoot 58 is mounted in a bearing 59 and provided with gearing 60, 61 for effecting a ' half-revolution to turn the matrix. The gear 61 is on a shaft 62 provided with a handle 63, and the shaft 62 is cut away opposite the shoot, leaving a segment 64, so that in one position of the shaft there is a free passage for the matrix, and in the other position the segment 64 blocks the end of the shoot.
