Abstract: 9602. Newton, H. E., [Hoe, R.]. April 26. Delivery apparatus; rotary machines.-Relates to stapling and delivery apparatus for printing-machines by which one or more printed webs are cut, folded, stapled, and delivered in the form of pamphlets or products having pages differing in number and size. Fig. 9 shows a section through the cutting and stapling cylinders of one form of machine, the mechanism being set or adjusted for producing papers or products from halfsheets, of various numbers of pages. The printed web or webs is passed from the printing-machine over a longitudinal folder, and, if desired, through web slitting and associating mechanism, to the cylinders A, B by which it is cut into sheets by the cutting- blades C on the cylinder B co-operating with cutting-grooves on the cylinder A. The leading end of each sheet is engaged by pins 2 projected from the cylinder by cam &c. mechanism, and withdrawn to release the sheets for folding along the stapled line by the folding-blades F into the rollers 20, 30. From the rollers 20, 30 the sheets may be passed to delivery flys and tapes, or to further folding-apparatus. The wire staples are formed and inserted by the arms 15 projected from and withdrawn into the cylinder B by cams 10 and springs &c. There may be several sets of stapling-mechanism, placed longitudinally, some of which may be rendered inoperative so that wide or narrow webs may be stapled as required. The projecting end 12 of each stapling-arm 15 is in the form of a fork into the recess of which the wire is pressed to form the staple by a stationary anvil 34. There are grooves in the recess of the arm 12 to receive the legs of the staple. Wire is fed to the shoulder or recess 19 in the anvil from a reel by a pair of feed-discs operated by gearing &c., and the length of wire is cut off at the time that it is gripped against the recess 19 by an abutment or shoulder 18 on the arm or fork 12. The wire is cut by a pivoted blade operated by the arm 12 as it passes. The folding and cutting &c. mechanisms are specially arranged so as to be adjustable for cutting, collecting, stapling, folding, &c. to produce papers or pamphlets having various numbers and sizes of pages. The stapling-mechanism may be rendered inoperative, at alternate revolutions &c., as is required when collecting sheets on the cylinder A, either by varying the amount of wire fed to such mechanism, in which case it would make an ineffective movement when no wire is fed, or by withdrawing or rendering the staple-forming arm inoperative at the required intervals. Another arrangement of machine is described in which the sheets are collected upon a separate cylinder instead of upon the cylinder carrying the folding-blades; and in which means are provided for feeding cover sheets which are associated and stapled with the other sheets so as to form covers to the papers. A third form of machine is described, in connection with which an improved stapling-mechanism is employed and is described in detail. Fig. 68 shows an end view of the delivery and stapling cylinders C<2>, D<2>, and Fig. 74 a section through one of the stapling- mechanisms. The staple-bending fork or arms 330 are upon a disc 331 sliding in a socket 436 in the cylinder C' and pressed outwardly by a spring 333. Between the arms 330 is a sliding clincher which presses the staples into the sheets and clinches them. On the clincher is a stem 335 surrounded by a spring 336 by which it is pressed outwardly. Across the bending-arms and clincher is formed the recess or shoulder 18, which co-operates with the shoulder 19 on the anvil 350 to hold the wire during cutting &c. The recess 19 is formed upon a yielding pivoted piece 385 in the anvil 350, and a rib 384 on the anvil forms a continuation of the projecting part of the piece 385. The end of the clincher is recessed to clear this rib. The ends of the legs of the staple are bent further inwards by means of inclined plates 314 which press them into grooves 304 in the sides of the anvil 350. The staple is clinched against a grooved clinching-block 346 mounted in a piece 345 adjustable on the cylinder D<2> by screws 393, 394, 395. The bending-arms are withdrawn gradually into the socket 436 as they move over the anvil with the staple, by means of a rock arm 341 on a shaft 372 operated by an arm 373 engaging a fixed cam 375. The delivery arrangements and their adjustments and operation for the production of various products are fully described in the Specification. Specification No. 3394, A.D. 1893, is referred to.
