Abstract: 14,326. Linotype and Machinery, Ltd., Pearce, H., and Billington, J. E. June 20. Magazines and escapements for type-bar making machines. Several magazines are arranged in pairs so that different pairs can be brought into operative relation to two fixed distributors and assembler - plate entrances. The column of magazines is supported on a frame 2, Fig. 1, which can be raised and lowered in known manner by means of two rockshafts 5, 6 which are connected to the frame 2 by arms 7 and links 8. The shaft 5 is operated by a hand-lever 13, and the two shafts are connected by arms 9 and an adjustable link 12 by means of which the inclination of the magazines can be adjusted. The escapements 16 of the upper magazine of each pair are on the upper side, and those of the lower magazine on the lower side. The escapements are operated by two sets of strikers or levers 18, 19 to which are connected links 22, 24. The lower ends of the links are engaged by the hooked ends of two sets of escapement-rods 27, 28 which are operated by a single set of key-rods in the manner described in Specification 19,375/11. The striker-levers and the links 22, 24 are carried by the pivoted assembler-plate entrance 37, and the escapement-rods must therefore be disengaged from them at the instant of opening of the assembler-plate. A comb-plate 32 operated by springs tends to retract the escapement-rods but is prevented by a stud 39 on the assembler-plate from doing so until the plate is opened. The assembler-plate is pivoted to an arm which is pivoted to the machine frame to enable the plate to be swung back against the right-hand side of the machine. An additional pivoted arm may be introduced' to permit of a linear movement of the plate during opening and closing. A track may be provided for supporting the weight of the plate. The plate is guided into position during closing and is locked by latches. The pi-stacker or pimagazine is carried by the assembler-plate and is connected with the distributors by flexible shoots. The entrance 10<a>, Fig. 10, of the lower magazine is provided with guide-grooves for the matrices instead of the usual partitions in order to prevent the obstruction of the entrance by a matrix having bent or distorted lugs. The upper end of the entrance is provided with the usual laterally-movable partitions 64 whereby a distorted matrix which enters the entrance effects the stoppage of the distributor. The two magazine entrances are pivoted so that they can both be turned rearwardly to permit both the magazines in use to be inspected and cleaned. Hinged flaps 65, 66 are provided at the upper ends of the entrances to enable obstructing matrices to be removed, or for other purposes. Distributing matrices. - Of the two distributors, that for the upper magazine is lower and more forward than that for the lower magazine. All the matrices are raised to the lift-box of the upper distributor, but the matrices for the lower distributor have notches in their feet which co-operate with a supporting rail 60 so that they are supported at too low a level to engage the screws of the upper distributor. The notched matrices therefore fall down a shoot 61 leading to the lower distributor. To facilitate removal of the separator-box, the separator-box cam is rotatably attached to and removable with the box. The cam is loose on its shaft, from which it is driven by a clutch. The upper distributor is driven from the lower through a clutch so that the upper distributor may be stopped without affecting the lower, but stoppage of the lower also stops the upper distributor.
