Abstract: 7889. Cassidy, P. F., and Doherty, N. F. April 5. Affixing labels.-Relates to machines, for affixing labels to bottles and other curved bodies. The paste receptacle 6 is constructed as described in Specification No. 14,521, A.D. 1901. The machine consists of a frame 1 supporting an open casing 2 having bearings 3 for two parallel guide-rods 4, upon which travels a carriage 5 carrying the paste receptacle. The carriage is moved forwards by a treadle 13, acting through a link 12, shaft 9, and links 8, 7, and is returned by a spring 14. The label hopper is carried on a frame 15, supported within the casing 2 by a spring 18 surrounding a rod 16, the lowered end of which, when the frame is in its raised position, is directly above a dog 19 extending from a hub 20 loose on the shaft 9. The dog has a side lug, normally held against a shoulder of a collar fixed on the shaft 9 by a weight 23 carried by the hub 20. When the treadle is depressed, the dog 19 is thrown forwards, and releases the lower end of the rod 16. Mounted upon the frame 15 is a plate 24 having removable vertical pins 25 which pass through holes in a plate 26 resting on the edges 27 of the casing and used to carry the packet of labels. At the front of the plate 26 is a slot 28, adjoining which is a support 29 to raise slightly that end of the pile of labels. The pins are removable and adjustable to accommodate labels of different sizes. Along each side of the frame 15 are the fixed tracks 30, to one of which a rack 31 is loosely held by screws 32 working in inclined slots 33. A pin 34 from the rack extends into a slot 35 in the casing, so that, when the frame is lowered, carrying the tracks 30 with it, the rack is forced slightly above the tracks. The axle of the paste roller carries two wheels 37, which run on the tracks 30, and one ratchet-wheel 37<a>, which gears with the rack bar 31 when the paste receptacle moves backwards. When the latter approaches the end of its backward travel, inclines 38 engage the wheels 37 and raise the receptacle from the frame 15, which then rises under the recoil of the spring 18. In the forward travel of the paste receptacle, its weight depresses the frame 15, and the pins 25 are lowered out of the way of the roller. When the frame rises, the dog 19 again takes up its position beneath the rod 16. To hold the labels while being pasted, a hook 41 is used. It is raised and lowered along with the frame 15, and is given a quarter turn, to grip or release the labels, by forming part of a rod 40, which has a sleeve 43 in which works a rod 44 operated from the shaft 9 by a lug 48, a link 47, and an arm 46. When the frame 15 is lowered, the hook grips the labels, and the paste roller on its return movement then pastes the top label, the roller having a central groove 49 to accommodate the hook. After the label has been pasted, the bottle is placed by hand in the position determined by the adjustable gauge 50 having an adjustable stop - plate 54. The bottle is then passed to an endless band 5, which is hung on crank shafts 58 carried by the stand 1, and is drawn tightly round the bottle in consequence of the weight of the latter. The shafts 58 have intermeshing gear segments 59, and are returned to their position, on the removal of the bottle, by a spring.
