IPC: B65C9/08
Filed: 1919-08-08
Abstract: 139,108. Powley & Sons, R., and Powley, M. Aug. 8, 1919. Labelling. - Relates to bottle-labelling machines of the type having a pneumatic carrier adapted to convey the labels from a holder to a gumming- device and thence to the bottles. A suction tube 38 is slid ably mounted in a cross-head 37 adapted to reciprocate on guide-bars 36 carried by a bracket 35, which is adapted to reciprocate on vertical guides 34. A roller 52 mounted in an adjustable gum-bath 51 is rotated by a belt 54 weighted at one end and connected at the other to an oscillating lever 44, in such manner that, 'in the passage of the carrier from the pile of labels 100 to the bottle A, the roller rotates in the direction of travel of the label, which passes over and in contact with the roller. At the moment the tube 38 descends to place the label on the bottle, wiper-arms 66, Fig. 5, carried by the cross-head continue their descent with the latter and press the flaps 66b upon the label. Projections 66d on the arms then meet cam-surfaces 67 on the tube 38, and the arms are forced apart. In the course of the descent of the cross-head, a spring-pressed lever 69 is moved to insert a shoulder 69<b> between a stop-collar 38<a> on the suction tube and the cross-head, so that when the bars 36 rise and the tube is moved towards the labels, the tube clears the gumming-device. When this has been passed, the lever 69 strikes a projection 80, the shoulder is withdrawn, and the suction tube falls. The labels are held between two pairs of uprights 50b, the distance between which is adjustable to accommodate different sizes of label. The bottles are conveyed in trough-shaped pieces 32 in an intermittentlymoving conveyer 7.

Abstract: 1,159,754. Rolling tubes. ELEKTROSTALSKY ORDENA LENINA ZAVOD TYAZHELOGO MASHINOSTROENIA. 28 April, 1967, No. 19747/67. Heading B3M. A mill for cold rolling tubes includes a reciprocating roll cage C carrying a pair of grooved rolls, and mechanism for feeding a billet E forwardly, in its delivery direction, and for turning the billet at both the forward and rearward positions of the roll cage. The cage C is reciprocated by crank mechanisms J driven from a motor G, while cam clamps M serve to turn the billet upon rotation of a first output shaft 9. Feeding of the billet is performed by a holder 0 which is moved forwardly by a screw and nut mechanism 22, 21. Levers 3 and 4 interact with a cam 2 to control the billet indexing, the cam being rotated by a shaft 1 of a motor driven gearbox D. In the rear position of the cage C, the lever 4 is moved by the cam such that a second intermediate shaft 10 is turned, thereby resulting in turning of the output shaft 9 via a clutch 23 and gears 24, 25, 7 and 8. Additionally the shaft 10 transmits its movement through linkwork 11 to a third intermediate shaft 12 which causes feeding of the billet via a clutch 14 gears 15, 16, 18-20 and the screw and nut 22 and 21. The lever 3 moved simultaneously with the lever 4 but its motion is not transmitted to the shaft 9 due to overrunning of a clutch 6. In the forward position of the cage the motion of the lever 3 is transmitted by the clutch to turn the billet, while the motion of lever 4 is prevented from being transmitted by overrunning of the clutches 23 and 14.
