Abstract: 23,000. Lock, W. H., Pearce, H., and Billington, J. E. Oct. 18. Linotype machines.-Relates to means for facilitating the changing of the magazines. The magazine frame 2 is supported at the front by set-screws 16, Fig. 1, and at the rear by a shaft 17 which is engaged by hooks 18 fitted with set-screws 19 which bear against the shaft. The frame is retracted in order to disengage the escapement levers 5 from the links 7 prior to the removal of a magazine by means of a hand-lever 20 on the shaft 17 and arms 21 on the shaft engaging stud's 22 on the frame 2. The bottom magazine is held in position on the frame 2 by means of bars on the underside of the magazine extending from front to rear and from side to side and engaging grooves in the frame. Each magazine has along the rear and side edges of its upper face strips 28 upon which the magazine above rests, and the bottom plate of each upper magazine is stiffened by tranverse bars short enough to fit between the strips 28 of the magazine beneath. Each upper magazine is adjusted laterally by means of setscrews 30 working in the side plates of the magazine near the rear corners and bearing against brackets 32 fixed to the frame 2. Hooks 35 fast to and depending from the magazine near the front are engaged by set-screws 33 carried by the magazine below. The hooks 35 also engage inclined lugs 36 on the lower magazine. The magazine entrances 13, 15 are pivoted on the magazine frame 2 and are automatically rocked, when the frame is moved to the rear, to prevent them from fouling the distributor. The entrances are separated by a plate 39 pivoted to brackets 40, which are pivoted on the frame 2 and are held in normal position by springs 42. An arm 49 on the magazine entrance 15 is connected by a slotted link 45 with a quadrant 44 on the shaft 17, so that when the frame 2 is moved to the rear by means of the hand-lever 20, the entrance 15 is rocked away from the magazine. The pivot 81 of the entrance 13 is engaged by a slot 55 in a plate 53 having a rounded end 54 around which passes a flexible band 58 attached to the quadrant 44. A pin 56 on the entrance projects through the slot 55, so that the plate 53 and entrance 13 are rocked by the hand-lever 20. The slot 55 permits the plate 53, when it has reached a vertical position, to move downwards a short distance against the pull of a spring 60. The band 58 may be replaced by a rigid connexion, such as a rack and pinion. The magazine frame 2 is tilted to permit of the removal of the magazines from the front by means of levers 63 connected by links 68 to a hand-lever 65. The top magazine is removed by moving it to the rear by means of grips 71 until the hooks 35 are disengaged from the lugs 36. The magazine is then raised and drawn forwards until lugs 76 engage and rook forward a pair of arms 72 on a shaft 73. The magazine is then suspended by means of the lugs 76 from hooks 75 on the arms 72 and is lifted off the machine. When the magazine is replaced, the grips 71 move back the arms 72 into their normal position. In a modification, the arms 72 are replaced by sliding arms. Specification No. 15,058, A.D. 1904, is referred to.
