Abstract: 6346. Brougham, F. J., [administrator of Friedmann, H.]. March 15, 1909, [Convention date]. Setting type; keyboards and driving-mechanism.-Relates to multiple-magazine machines. (1) The type-pushers 17, Fig. 1, are mounted in an adjustable carrier 35 for shift to the various magazines A, B, C, D, which are normally held out of the way by bell-crank levers 45<a>, Figs. 1 and 6. The carrier 35 is connected to an arm 39 of a hand-lever 37, on which is a second handle 45 pivoted for engagement in a series of notches 47 in a fixed segment. A pin 45<c> on the handle 45 effects the actuation of the bellcrank levers 45<a> through connexions 45h, 45<g>, 45<f>, 45e, 45<d>. (2) The key-levers 4, Fig. 1, operate striker-bars 5 of relay mechanism, comprising a ratchet-wheel 7 and a compound pawl 11 which is tripped into the path of an arm on the driving-shaft 13 and advances the spring- retracted type-pusher 17 by engagement of a nose 15 in a recess 16. (3) The magazines are formed of a metal plate 100, Fig. 6, grooved to receive channel-bars 101, and strengthened by lateral bars 102. The magazines rest on rollers 99, Fig. 1, in a receptacle 98, above separate mouthpieces 20, Fig. 6. To facilitate ejection of the types, the magazines are inclined slightly, and the floor of the mouthpieces 20 is inclined somewhat steeply. The magazines are normally closed by strips 103 provided with projecting pins 106 engaging notched levers 108 pivoted on the mouthpieces 20; when a magazine is lowered into operative position, the corresponding levers 108 drop into engagement with links 110 operated by a handle 112 to open the magazine. (4) Frequently - used types are repeated in adjacent channels, and used serially from these channels. For this purpose, the corresponding ratchet-wheels for each group of channels are mutilated and connected together to operate the compound pawl 11 serially. Justifying and trimming type; galley mechanism.-(1) The assembled line is transferred for wedge justification as usual between grippers 67, Fig. 5, on a carriage pivoted so that it can be depressed to engage the line and be coupled by means of a half-nut 75 to a traversing- screw 76. The left-hand gripper is adjustable on the gripper-bar 68; this is pivoted to facilitate the proper entry of the grippers into the linechannel. (2) The projecting ends of the stepped justifying-wedges are planed off, for which purpose the line passes in the line-channel between two plane-irons on a continuously-reciprocating carriage. (3) At the end of the line-channel the line is received on a slide 79, Fig. 5, on a member 77 adapted to be rotated to the galley 78 into the position shown in dotted lines, the slide 79 being simultaneously depressed by means of a stop 93 to leave the line free for transfer by a pusher 91. These parts are actuated by cams 81, 82 driven through a onerevolution clutch thrown in by the nut 75 at the end of its travel; a nose on the cam 81 engages the member 77, and a nose on the cam 82 engages a roller 88 on a lever 87 bearing against the pusher 91.
