Abstract: 2967. Lawes, G. W. Feb. 5. Labelling.-Relates to the general construction of machines for labelling tin receptacles &c. Labels are transferred by an adhesive separator 7 from a pile holder 44 to a carrier 13 on a rotating drum 6, which carries them under a pasting-device 24 and onward to meet tins which have been carried from a trough 10 by arms 4 rotating on a shaft 1. After a tin has received a label from the carrier 13, it is rotated to permit a wiping-roller 39 to affix the label around it. The pile holder 44 is pivoted at 48 and is raised to the separator 7 by a cam 38 on a shaft 49, Fig. 5, and a worm 51 on the shaft rotates a pinion 51<a> on the threaded stem 46 which carries the bottom 45 of the holder to feed the pile upwards as the labels are used. An intermittent rotation is imparted to the shaft 3 of the separator by a pawl 57, a connecting-rod 55, and a crank 54 on the shaft 49. The member 13 of the label separator is pivoted at 14 to the drum 6, and labels are gripped between its free end and hooks 23 pivoted at 14<a> to the drum, these parts being pressed together by the lever shown, acted upon by a spring 20 and bearing on a projection 21 of the member 13. The gripper is held open by a bolt 31 engaging beneath the head 6<a> of a bolt secured to the drum 6. When the separator 7 presses a label against the member 13, an arm 34 carried by the shaft 3 rocks a lever 35 which withdraws the bolt 31 from the catch 6<a> and allows the gripper to close on the label. Cam surfaces 31<a>, 31<b> carried by the bolt 31 and the drum 6 are then in contact and prevent the member 13 from being separated from the hooks 23. When the arms 4 are about to press a tin on to a pasted label carried by the grippers, a spring-controlled arm 36<a> knocks the lever 35 and frees the bolt 31 from the cam surface 31<b> to allow the member 13 of the grippers to be pressed in by contact with the tin, thus releasing the label. The bolt then drops beneath the catch 6<a> and holds the grippers open until another label is placed therein. The resilient arms 4 are adjustable in length and are adjustably mounted upon the shaft 1, and they are provided with swivelling jaws 8 between which the tins are gripped. As the arms 4 rise to meet a tin in the trough 10, they are forced apart by fixed cams 9, and finally pass these cams and spring together to grip the tin. Cams 8<a> on the jaws 8 engage with cams 9<a> to cause the jaws to grip the tins at the proper angle, the jaws conforming in shape to the tins. After a tin has taken a label from the grippers 13, 23, a toothed wheel 41 on one of the jaws 8 engages with racks 42, 43 which rotate the jaws and tin first in one direction and then in the other, to allow the wiping-roller 39 to affix the label around the tin, the roller being carried by a counterweighted arm 40. According to the Provisional Specification, when round tins are being labelled they are made to rotate immediately they contact with the pasted label, so as to cause a sufficient length of the label to adhere to the tin before it is released from the label carrier, and the pile holder may be carried by a weighted lever which presses the pile up to a fixed stop, the separator 7 being depressed and raised to pick up the top label.
