Abstract: 110,200. Linotype & Machinery, Ltd., (Mergenthaler Setzmaschinen - Fabrik Ges.). Oct. 14, 1916. Distributing matrices; magazines; escapements.-In machines in which the distributor bar alone or in conjunction with an adjacent device effects the distribution of matrices, dies, &c. according to fount and character, the distributor bar is moved laterally over the magazine entrances and the tooth combinations are arranged so that the matrices are released when the distributor bar is over the corresponding magazine; or the distributor bar may deliver to intermediate magazines having fount-separating devices. In the machine shown in Fig. 1, the distributor bar 8 is secured to arms 9 which are pivoted at 10 and are rocked by a cam 12 and a spring 30 or by a grooved cam to bring the distributor bar over the channelled entrances to tne magazines 2, 3. The tooth combinations occur at intervals equal to half the width of a channel and alternate combinations release matrices for different magazines. The channels in the entrance to the magazines 2 are half the width of a channel in advance of those for the magazine 3, and the feed-screws for the matrices are timed so that the matrices are fed through half the width of a channel as the distributor bar swings from one entrance to the other. The feed-screws and the cam 12 may be geared by chains to a sprocket-wheel co-axial with the pivots 10. The matrices pass to the distributor bar through a shoot 17 which rocks with the arms 9. In modifications, a single distributor bar is arranged to deliver matrices to more than two magazines, for example six; or the matrices may be divided by a fount-separating device arranged in the entrance to shoots leading to two distributor bars which are mounted to move together and each deliver matrices to three magazines. In these modifications, the distributor bar or bars may be mounted on a parallel linkage and the rocking-cam may be formed with dwells for arresting the distributor bar or bars over the magazine entrances. In the machine shown in Fig. 8, a distributor bar delivers matrices to three intermediate magazines 20, 21. 22 each associated with two magazines of the set of magazines 2 - - 7 and each provided with fount-separating devices for delivering matrices to either of the two associated magazines. The distributor bar is mounted on a parallel linkage 23, 25, and the. rocking-cam 12 is formed with dwells. A fount-separating device consisting of a rocker 33 is arranged under each channel of the intermediate magazines 20, 21, 22, and the matrices are formed with inclines 32 for engagement with rollers 38 on the rockers, the matrices for the magazines 2, 4, and 6 having the inclines sloping in the opposite direction to the inclines on the matrices for the magazines 3. 5, and 7. The rockers are each pivoted at 34 and are held in neutral position by springs 35. The rollers 38 are preferably grooved and formed of yielding material. The matrices are positively propelled against the rockers by means of continuously-driven bands 36 which engage the edges of the matrices. The fount-separating devices may consist of blades adapted to tilt the matrices to the right or left by engaging foot recesses. In the machine shown in Fig. 13, the rocking distributor bar 8 delivers matrices to three intermediate magazines 20, 22, 24 which are pivoted at 39 and are each rocked by a crank 40 and links 41, 41<a>, 41<b> over the entrances of two magazines of the set of magazines 2 - - 7. The channels of the intermediate magazines are each provided with the fount-separating device shown in Fig. 14 and comprising feelers 44, 44<a> escapement-levers 51, 51<a>, and escapement-locking levers 50, 50<b>. The feelers co-operate with recesses 43 in the matrices 42 of one fount, the matrices 42<a> of the other fount not being provided with recesses. Levers 46, 46<a> pivoted on the intermediate magazine are provided with springs 45, 45a engaging the feelers and with rollers adapted to enter fixed cam-grooves 47, 47<a>. The levers 50, 50<b> are operated by levers 48, 48<a> which are pivoted on the intermediate magazine and are provided with rollers adapted to enter fixed cam-grooves 49, 49<a>. The escapement-levers are operated by fixed springs 52, 52<a>. When the intermediate magazine swings to the left, the lever 48 lifts the lever 50 into engagement with the escapement-lever 51 and the lever 46 is rocked and causes the spring 45 to press on the feeler 44. If a matrix 42 is presented, the feeler enters the recess 43 and returns the lever 50 to the normal position shown, and on further movement of the intermediate magazine, the feeler is withdrawn and the escapement-levers are operated by the spring 52 and release the matrix 42. If a matrix 42<a> is presented, the feeler 44 is blocked by the plain edge of the matrix and the lever 50 remains in locking position and prevents operation of the escapement-levers. When the intermediate magazine moves to the right, the locking-lever 50b cooperates with the feeler 44<a> and the escapementlever 51<a> permits or prevents the release of a matrix according to whether a matrix 42<a> or a matrix 42 is presented. The arrangement shown in Fig. 14 may be applied to distributing matrices to two magazines from a single fixed distributor bar. In a modification, the mechanism is arranged at one side only of the intermediate magazines and each fount-separating device comprises only one escapement-lever, one locking-lever and one feeler, an arm mounted on the feeler controlling the engagement of the locking-lever with the escapement-lever.
