Abstract: 9957. Collon, E. L. May 8, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Folding paper; feeding sheets.-In machines for folding serviettes, paper, fabrics, and the like, more especially of the type described in Specifications No. 2711, A.D. 1900, No. 1218, A.D. 1901, and Nos. 17,608 and 24,098, A.D. 1904, [Abridgment Class Washing &c.], the cams 9, 10, which control the movements of the folding- blades 3, 4, a r e automatically adjusted upon the shaft 11 according to the length of article to be folded, thus obviating the re-keying of the c a m s when treating articles of different dimensions. The serviette is fed along a table 1 and, while pasaing over a gap 44 therein, supports a tube 43 carried by means of a lever 27 in a hook 42 formed at the end of a two-armed lever 19 pivoted at 22. The other arm 20 of this lever carries a roller in contact with the edge of a cam-plate 21 secured to the main shaft 11. A lever 23, also pivoted at 22 and having a screw 24 bearing on the arm 20, terminates in a pawl 25 adapted to engage with a ratchet-wheel 26 loose upon the shaft 11 and fixed to a pinion 30 connected to the shaft through a spring 30<b>. The pinion 30 meshes with a gear-wheel 31, secured to the shaft 32, which is free to rotate and is carried by the cam-plate 21. Spur-wheels 51, 53 fixed to the shaft 32 engage with spur-wheels 50, 52 secured to the cam-plates 9, 10, which are loosely mounted on the shaft 11. The cam-plate 21 has pivoted to it a pawl 34 for engagement with a second ratchet-wheel 33 secured to, or as shown, forming part of, the ratchet-wheel 26. The action is as follows : The arm 19 first occupies the position 45 to permit the serviette to be fed along the table 1. The cam 21 then allows the arm to fall to the position 46 so that the serviette is held between and drawn onwards by the rollers 17, 18. By virtue of the depression 48 on the cam 21, the levers 19, 27 next occupy the positions shown, with the tube 43 resting upon the serviette. The pawl 25 is now in engagement with the ratchetwheel 26, the stoppage of which and therefore of the pinion 30 causes the gear-wheel 31 to roll upon the pinion 30 and consequently the shaft 32 to rotate upon its own axis, and the rotations of the cams 9, 10 to be retarded against the action of the spring 30b. The retardation is terminated by the fall of the tube 43, which is then nipped between a roller 41 and a roller 40 on the end of a lever 38 connected to an arm 39. The resulting lateral movement of the roller 40 actuates the arm 39, which thereupon pushes against the hook 42 and raises the arm 19 into the position 46. The pawl 25 is thus disengaged, but the cams are retained in their new positions by the pawl 34 until this pawl is operated by contact with a fixed stop 37, whereupon the cams return to their original positions under the action of the spring. After being folded transversely, the article travels in a direction at right-angles to its first path and over a grille where it receives the longitudinal folds.
