Abstract: 13,062. Adam, M. A., [Standard Labeling Machine Co.]. June 9. Affixing labels.-In a bottle-labelling machine, the labels are lifted one at a time from a pile L, Figs. 1 and 2, and are at the same time pasted &c. at their ends by two hollow pickers 14 having finely-perforated faces through which the paste or glue is forced by a pump P. The pickers 14 are of various shapes, according to the shape of the labels, as shown in Figs. 14 and 15, and are secured to arms 13, which are pivoted to a support 12 projecting from a block 11. The labels are carried forwards by the pickers on to two flexible wipers 15 of leather, rubber, &c., and are drawn off the pickers and properly affixed as the bottles are forced downwards between the pickers and wipers. The arms 13 and the wipers 15 are adjustable on their supports to suit different sizes and shapes of bottle. The block 11 is movable vertically on guide-posts rising from a carriage which is reciprocated horizontally on the bed-plate B by a track-cam 40 on a sleeve 32 surrounding the shaft 33 of the driving- pulley W. The pump P is also carried by the sliding carriage, and is operated by a fixed incline on the bed-plate, against which an internal spring depresses the piston-rod, the stroke being regulated by a screw collar 21 which limits the downward motion of the piston. The rotary valve for opening the pump to the supply and outlet pipes s, o is operated by fixed pins 23 and a ledge 22 acting on a tappet T at its lower end. When a bottle is inserted into the machine, a vertically-reciprocating plunger 17 clamps it down on to a central support S, which is carried by a vertical sliding rod 16 constrained by spring toggle-levers 43. After the label is affixed, the toggle-levers pass their deadcentre, and depress the support S so that the bottle can be withdrawn. The machine, when in operation, stops with the parts in the position shown in Figs. 1 and 2 after the withdrawal of a labelled bottle, and is re-started by pressing another bottle into position against a spring trip-plate 41. Motion is transmitted from this plate to a cranked lever 24, Figs. 1, 2, and 4, on the block 11, so that a spring- pressed rod 25 is free to rise and to withdraw a stop pin from engagement with a tooth on a clutchcontrol collar 27. Fingers project axially from this collar between the rollers on the inner part of a roller clutch 29, and normally hold the rollers in the non-clutching position, but are drawn round by an internal spring within the collar 27 when the above action occurs, and then allow the parts to interlock. The sleeve 32, carrying on its end the inner part of the roller clutch, is thus driven from the shaft 33 carrying the outer part, but is again stopped after the completion of a revolution, as a hook cam 31 upon it then engages with a roller 30 and draws down the rod 25 into position to be again held by the lever 24 on the return of the block 11. A crank 34 on the sleeve 32 acts through a link 35 to operate the plunger 17, and also through the rod 25 and a link 36 to raise the rod 16 and support S. A cam 37 acts through a linkage 42 to raise the spring support 18 of the labels when the pickers 14 are above them, and another cam 38 at the same time engages with a roller and draws down the pickers. The paste &c. is supplied from a closed can &c. 44 through closed passages, and the machine can be kept for an indefinite time ready for immediate use by the application of a damp cloth to the perforated faces of the pickers.
