Abstract: 392,019. Type-bar-making machines. HART, H., 9, Kingsway, London.-(Mergenthaler Linotype Co. ; 29, Ryerson Street, Brooklyn, New York, U.S.A.) July 25, 1932, No. 20890. [Class 100 (iii).] Magazines.-In a typographical composing and distributing machine, in combination with a main frame designed to support a magazine unit in a given forwardly inclined position between matrix assembling and distributing mechanisms so as to enable the unit to be moved rearwardly about a pivotal axis x located below and approximately centrally of said unit to a reversely inclined position to present a magazine for removal at the rear of the machine, there is provided a magazine unit adapted to occupy the same position in the machine but movable upwardly about an axis located at the upper end of the unit from one to another forwardly inclined position to enable an operator at the front of the machine to remove a magazine from and reinstate a magazine in operative position. The main frame comprises, as usual, a front assembler bracket A, and a rear distributer bracket A<1> ; to the latter is attached by screws J<1> a pair of plates J in which is mounted a pivot rod K for the upper end of the magazine base frame H, while to the former is attached a pair of supporting plates L, each having two arms L2, L3, and of which the arms L2 have adjusting screws L<4> upon which the frame H normally rests. The magazine entrance E is of the usual type, and is swung rearwardly into its inoperative position by a hand-lever G and a link G<2>, this rearward movement also serving to arrest the operation of the matrix distributer by releasing a stop-arm which 'moves under spring action to disengage a clutch operating the distributer. The stoparm is depressed and the clutch re-engaged on the return of the entrance to its operative position. The magazine frame H is secured to the rod K by the customary pivotal mounting, comprising adjusting-screws H<7>, plates H<8>, and pins H<9>. Lateral adjustments of the magazine are effected by means of screws carried by the plates J and bearing against opposite edges of the base frame. The magazine A is held on the frame H by a longitudinal tongue on the magazine which engages in a slot in the frame and by a cross-bar D<1> which co-operates with two sustaining plates H<1> arranged at opposite sides of the frame. The plates H<1> are bevelled at the front to facilitate replacement of the magazine. The lower end of the base-frame H is provided with the usual rotary cams H<4> fast to a shaft H<5> journalled in the frame, and the outer sides of the cams carry hook-shaped arms H<6> which serve to rotate the cams and also to support the magazine during its removal &c. The cams H<4> co-operate with rollers L<5> mounted in the arms L<3> of the plates L and in the normal position these rollers rest in notches H<10>. When the arms H<6> are moved forwardly, the cams H<4> bear upon the rollers L<5> and in rotating raise the frame H ; the magazine crossbar D<1> is then disengaged from the plates H<1> and the magazine slides forward until the ends of the cross-bar, which project laterally for this purpose, engage the hook-shaped ends of the arms H<6>. In order to ensure that the magazine entrance is first swung out of the way and that the distributer is stopped before the magazine is removed, a locking hook M is carried by the link G<2> which is so arranged that, when the entrance is in its operative position, the hook overlies the arms H<6> and prevents their operation.
