477,533. Type-bar-making machines. MERGENTHALER LINOTYPE CO. July 1, 1936, No. 18256. Convention date, Dec. 30, 1935. [Class 100 (iii)] Magazines.-Relates to machines of the kind having series of main and auxiliary magazines arranged side by side, each series being movable independently of the other to bring any magazine into operative position. Each series of magazines is, as heretofore, arranged in a movable shift-frame, which is, in turn, mounted in a supporting-frame, which can be rocked upwards to permit magazines selected for removal to clear the assembler devices. According to the invention, means are provided in each supporting-frame for adjusting the associated shift-frame, such means being operated by a single device on the main frame of the machine. The base frames of the main magazines A, Fig. 2, and of the auxiliary magazines A<1>, are secured to side-plates C, C<1>, so as to form shift-frames. The shift-frames are mounted in relatively fixed supporting-frames D, Fig. 1, which can turn about pivots D<1> at their upper ends, and can be raised by toggle-mechanism operated by hand-levers H<3>. The shift-frames are raised and lowered by pairs of cams K, K<1>, fixed on shafts K<2>, K<3> mounted in the supporting-frames. The two shift-mechanisms are operated by separate sets of connections, comprising bevel-gearing and two vertical shafts M<3>, N<8>, from a single crank-handle L, to which either set can be connected at will. The handle is connected to either shift-mechanism through a gear P<2>, Fig. 3, meshing with two gears P<3>, P<4>, which can both slide and rotate on shafts M<8>, N<9> connected to the shift-mechanisms. Either of the gears P<3>, P<4> can be locked to its shaft by means of keyways in the gears, which are adapted to engage short keys on the shafts. The gears are shifted by a lever P<7> operated by a knob P<9>. As the gears can only be shifted when their keyways are in alignment with the keys, the gears and the handle are normally locked in a suitable position. This is effected by a gear R<1>, Fig. 1, having a recess to receive a spring-pressed pin R<5>. The pin can be withdrawn, to permit a change of magazine, by a lever R<8>, operated by a vertical rod R" and a hand-lever S<3>, mounted on a shaft S<2>. The handle L has a frictional connection to its shaft, to prevent damage in the event of obstruction. Brakes are provided on the shafts M<8>, N<9> to take the weight of the magazines as they are lowered. The connections for operating the shift-frame of the main magazines are maintained during the movement of the supporting-frame, the shaft M<3> being made telescopic for this purpose. Those for the auxiliary magazines, however, include a pair of meshing gears N, N<1>, Fig. 2, one on the cam shaft and the other on the main frame, so that the connections are broken when the supporting-frame is raised. When disengaged, the gears N, N<1> are locked in proper relation by spring-pressed pins, which engage holes in the gears. The hand-lever S<3> is locked so that the magazines cannot be shifted if any matrices protrude from the lower end of a magazine in use, or remain on the distributer, by connections from the usual feeler devices to the shaft S<2>. When the handlever is operated, a half-round bar is rocked, so as to push back any escapement levers, which, being in the forward position, might cause damage. In case matrices stick between the conductor-channel E and a magazine and so prevent a shift-frame, when being lowered, from following its cams, banking-blocks V, V<1> are provided on each shift-frame, so as to co-operate with a retractable dog V<3> and support the frame when either the intermediate or the lower magazine is in operative position.
