Abstract: 15,653. Woosnam, A., [American Dairy Supply Co.]. July 5. Stapling.-Relates to apparatus for making cover or closure disks having handles or tabs exposed on or at the tops thereof, and comprises mechanisms for feeding a ribbon or band of disk material and imprinting it at regular intervals, for feeding a narrow band of paper or other tab material and forming tabs therefrom, for stapling or clipping the tabs to the disk ribbon at regular intervals, and for cutting disks from the ribbon, each disk having a handle or tab. In the machine illustrated, strips of material a, c, Fig. 1, to form disks and tabs respectively, are fed transversely to each other. Suitable lengths of material care cut off to form tabs, and these are secured to the disk stock at regular intervals by staples or clips formed from wire b, after which the disks are cut from the strip a. The disk stock may be imprinted at intervals with advertising or other matter. All the motions in the machine are derived from a cam-shaft 105, which operates (1) the disk stock, mutilated feedrollers 10, and printing-rolls 17, 18 through a shaft 71 and train of gearing; (2) the tab stock feed-rollers (not shown) through a shaft 50 and train of gearing; (3) the wire-feed slide 83 by a lever 89 through linkwork and a cam 112; (4) a staple-forming and tab-stock cutting slide 41, and staple-driving hammer 52, through links 121, 125 and cams 120, 124; (5) a staple clinching-hammer 66 through linkwork 65, 67 and a cam 70; and (6) the plunger 76 of the disk cutter through a link 117 and cam 116. The finished disks are discharged through a pipe 74. The disk stock passes through a tension device consisting of spring plates 7, Fig. 1, and the tab stock through a similar device. The staples are formed on an anvil 54, Fig. 6, by the slide 41, which has a lower cutting-edge 42 adapted in its forward stroke to cut the tab stock against a fixed knife 43, and also a vertical cutting-edge 62 which shears the wire. The anvil 54 is carried by a spring- controlled lever 55 having a roller 58 bearing on a cam surface on the slide 41, so that, as the slide advances, it raises the anvil clear of the path of the staple-driving hammer 52. The ends of the driven-staple, Fig. 12, are deflected towards each other by the walls of a die 64, ready to be clinched by the plunger 66. A presser foot 80, Fig. 12, holds the disk stock against a die 72 while the disks are cut by a die 75. The presser foot is spring-controlled, and is moved into operative position by a roller 82, Figs. 1 and 12, carried by the wire-feed slide 83. The wire-feed slide carries a fixed jaw 85 and a pivoted jaw 86, which is adapted to be engaged by a toe 91 formed on the lever 89. The point of engagement of the pivoted jaw with the wire and the movement of the slide are regulated by altering the limits of movement of the lever 89 by a fixed stop 94 and a thumb-screw 93. The wire tension device, Figs. 1 and 14, consists of a block 97 provided with fixed and movable jaws 98, 99. The movement of the upper jaw is controlled by a spring 104, anti-friction balls being placed between the jaw and the wall of the recess in which the jaws are situated. The stapling and tab-stock feed devices can be thrown out of action and the machine used for producing disks only.
