Abstract: 422,524. Type-barmaking machines. INTERTYPE, Ltd., Farnham Road, Slough, Buckinghamshire.- (Assignees of Freund, H. R. ; 360, Furman Street, Brooklyn, New York, U.S.A.) April 11, 1934, No. 10929. Convention date, Feb. 17. [Class 100 (iii)] In a matrix-composing and type-line casting- machine having a magazine stack comprising several magazines arranged one over the other and held at a distance apart by inclined supporting frames on which they are slidable towards the front, the magazines, or when applied to split magazines, the upper magazine halves 1, 2, 3 and the lower halves 4, 5, 6, are carried by the supporting frames 7, 8, 9, which are connected together by side parts 10, 11, and to enable the magazines or the lower magazine halves 4, 5, 6, to be easily removed, there are provided in each supporting frame 7, 8, 9, for each magazine half two sliding bars 21, which are arranged at each side and extend the full length of the frames and are kept in the working position by a stop 23 on the underside of each bar engaging behind a stop 24 on the particular supporting frame. The bars 21 move in grooves formed by the underside of the frames and by plates 25 let into the upper surface, and normally rest on the frames without touching the magazine to which they belong; as shown in Fig. 5, the magazine 4 is supported by bars 26, 27, 28 which rest on the frame 6 and are maintained in position by pins 32 on the sliding bars 21. The pins 32 and further pins 31 are provided on a thickened part 30 of the sliding bars which is level with the surface of the plates 25, and further projections 33 are provided on the ends of the bars. To release a lower magazine half 5, the appropriate bars 21 are lifted, pivoting about points 35 until the thickened part 30 comes against the transverse bar 28. This movement releases the stops 23 from the recesses 24, permitting the sliding bars and the magazine half to slide forward out of the frame 8, until the stops 34 engage the plates 25 ; in this position the magazine can be easily raised and removed. The bars 21 are connected together by a transverse bar which is provided with a recess fitting over a groove on the frame, and this and the pins 31 facilitate placing a new magazine on the bars. The lowermost frame 9 is provided with rollers running on tracks along which the magazine frames can be adjusted by operating a spur-wheel 16, meshing with a fixed rack 14, Fig. 2, to bring any required magazine opposite the assembler entrance 19. To lift the magazine stack far enough to enable the lowermost magazine to clear the entrance 19, the spur wheel 16 is reduced for a :part of its width with the exception of one tooth. A stop 39 fitting the reduced diameter is provided in the path of the spur-wheel, which extends further than normal, so that the operating shaft 40 can rotate the crank 41 until the long tooth on the wheel 16 engages the stop 39. As the shaft 40 is rotated, the lower end of the magazine stack is moved in a cycloidal path by an eccentric cam surface bearing against a projection on the frame 9, and the arrangement of the stop 39 and wheel 16 determines that, at the end of the traverse, the magazine stack is in an elevated position, with the lower end of the bottom magazine clear of the entrance 19.
