Abstract: 11,975. Brown, J. M. June 2. Feeding sheets in labelling-machines. Relates to improvements in bottle-labelling machines of the type-described in Specification No.7889, A.D. 1904, [Abridgment Class Labels &c.], to ensure the removal of only one label at a time, and to allow easy adjustment of the label bed-plate and the hopper pins. The label bed-plate 29, Fig. 8, has two series of parallel slots to accommodate the hopper pins 30, each separately adjustable by means of a screw rod 34 or by disengaging rack teeth 34<a>, Fig. 25, from a fixed engaging-plate 34<b>. The plate 29 is carried by two vertical rods 35, passing through tubular castings 36 and held up against stops by springs 37. Each rod 35 has a rack with which engage pinions on a shaft 41 fitted loosely in bearings 42 held in position by springs 43, which allow the label bedplate to be forced down-' wards without injury to the racks or pinions. Paste is applied to the labels from a receptacle 10 on a reciprocating carriage by a roller 20, the axle of which travels on rails 21 pivoted at 28. At the limit of the forward movement of the roller 20, the rails tilt and allow the roller to descend on to the top label. The rails are automatically returned to the raised position as the pasting-roller passes the pivots 28 on returning, thus raising the top label to permit a separating-finger 96 to enter thereunder. The label bed-plate 29 is fixedly held in its raised position while paste is being applied, and is then lowered against the springs 37 by cam action, leaving the topmost label adhering to the underside of pickers 46. An arm 97 actuates a lever 92, whereby a hooked retaining-rod 90, which normally engages the pile at one end, is moved out ofthe way, while the separating-finger 96 is projected over the pile. At this point the pickers 46 are raised out of engagement with the label pile, and the cam 46<a>, Fig. 2, allows the rod 44 to start moving downwards, releasing the arm 97 from engagement with the lever 92 to allow the label-retaining hook 90 to be moved forwards again above the label pile; and, when the rod 44 is freed from the cam, the label bed-plate is raised-by springs 37. The pickers 46 place the pasted label above a band 60, and a bottle placed above'and between the pickers is forced downwards upon the label by a presser 69. The pickers 46 are horizontal plates, with upwardly extending portions journaled on the two arms 47 of a rock-shaft 48, and are yieldingly held against ' stops 50 by coil springs 49 on the arms 47, allowing the pickers to move laterally out of the way of the bottle when the bottle descends. The rock-shaft 48 has at one end a crank 51 carrying a roller 52, which travels on a track 53 with a cut-out portion 54, into which the roller 52 enters as the pickers are lowered on to the top label, and from which the roller 52 is lifted by a cam-actuated triangular plate 55 to cause the pickers to rise with a pasted label adhering to them. The presser 69, by means of a trip arm 73 mounted on the rock-shaft 74, which is connected by a crank to a vertical rod 76, actuates a shifter 6 and clutch 4, whereby the banddriven pulley 3 drives the shaft 2. By means of the cam 87 on the countershaft 17, engaging with a link 88, the shifter 6 is held in position until the label has been caused to adhere to the bottle, the presser elevated, and the picker arms carried back and dropped upon the pile of labels.
