Abstract: 342,313. Printing-machines. QUICK, C. G. and DIGBY, C. B., 109, Borough Road, London. Oct. 30, 1929, No. 33031. [Class 100 (ii).] Fudge-boxes.- In a late-news cylinder a locking member movable into and out of locking position is provided for engagement with the usual fudgebox retaining- members. A locking - ring 14, Fig. 1, having for each dog 9 an inwardly projecting lug 15, is adapted so that one end face of each lug abuts against a shoulder 16 formed on the cylinder 1, and the other end face can be moved by partly rotating the locking-ring 14, either to abut against the outer faces of the dogs 9 when these are in clamping position, or to be clear of the faces of the dogs, which are thus free to be moved out of clamping position. The locking-ring 14 is provided with pins 17 which enter a circumferential recess formed in the cylinder 1 so that it is positioned axially; the ring, which is provided with finger grips 19, is located in either position by a spring-pressed ball located in a recess in the cylinder, the ball being adapted to enter recesses formed in the ring. In a modification the lugs 15, instead of projecting inwardly, are formed by cutting away portions of the ring itself so that they consist of axial projections from the ring which engage ribs extending from the upper surfaces of the dogs. Movement of the locking-ring is limited by providing in the ring a covered slot into which extends a screw from the cylinder. In another modification, shown in Fig. 8, the locking-ring is mounted at the end of the cylinder, and is formed with arcuate slots 24 through which extend large-headed screws 25 which retain the ring in position. When it is desired to lock the dogs, abutments 26 in the ring 14 are moved into position under the heads of screws 27 screwed into one of a pair of rods 28 which are under spring action and secured to each dog, while when it is desired to free the dogs, the cut-away parts of the ring are moved into line with the heads of the screws 27. Attachments may be provided on the cylinder for the reception of seal-printing devices. In all cases the slidably mounted dogs are urged under spring action into clamping engagement with bevels on the fudge feed-boxes, and actuating hand-grips are provided for moving the dogs out of clamping position. The cylinder is provided with driving feathers for the fudge feedboxes, and is secured on its shaft by set screws.
