200,658. Lock, T. J., and Sprenger, G. C. May 31, 1922. Stapling.-A stapling machine forms a staple and holds it while the curved and straight ends are bent at right angles to the body of the staple, which is then driven into a ticket, formed from printed web paper, with the pointed ends of the staple ready for attachment to any material, while the curved end of the staple is passed round the edge of the ticket and wiped underneath it. Wire is fed through a guide 1, Fig. 4, into grooves 3 in blocks 2, and also passing through a groove 6 in a plunger 5. The plunger is carried on a block 7 in a slide 8, and is operated by a bell crank 9, Fig. 2, engaging a cam on a main shaft 11. The wire is cut by a knife 12, Fig. 4, on the slide 7, and a staple is formed by the plunger 5 pressing the wire between the blocks 2. The complete staple is pressed into grooves 18, Fig. 5, between spring fingers 16 pivoted to a fixed frame 14. Within this frame a slide 19, Fig. 6, carries rams 24, 25, which engage opposite ends of the staple, the middle being supported in the groove 18. Thus the curved end of the staple and the two straight ends are bent downwards. The staple is now driven into work 31 by a ram 26 operated from an arm 27 off the printing platen, which is driven by a rod 30, Fig. 2, off the shaft 11. The rams 24, 25 are operated by a rod 21, Fig. 2, and bell crank 22 engaging a cam on the shaft 11. The staple ends penetrate the work 31, and the curved part of the staple passes down at the end of the work and is turned underneath it by a wiper 33, Fig. 6, which is pivoted at 34 and operated by a rod 35 connected to a crank 36 &c., Fig. 2.
