Tripping-arrangements. - In sheet-feeding mechanism for printing, folding, and like machines, of the kind in which a feed-member, such as a friction wheel, is alternately raised and lowered by cam mechanism, and can be tripped by a subsidiary cam and feeler mechanism, the subsidiary cam is arranged for actuation through toothed gear to render the tripping lift gradual. The friction wheel 8, Fig. 1, is normally raised from the pile of sheets 2, against the action of a spring, by means of a cam 20 on a driven shaft 19. through a roller 17 on an arm 15 on a shaft 12, another arm 13 on the shaft being linked to a bell-crank lever 7, 6 carrying the wheel 8. A third arm 16 on the shaft 12 carries a roller 18 riding on a cam 60 provided with a gear wheel 61 engaging a rack 57, which can be advanced bv a spring 58 to rotate the cam but is normally held retracted by means of a detent 55 on a shaft 53 connected by links 52. 54 to a bell-crank lever 25 carrying a pivoted feeler 26. When an advancing sheet meets the feeler 26, a pawl 22 associated therewith is swung into engagement with a ratchet disc 21 on the shaft 19, and thereby the lever 25 is rocked to withdraw the detent 55, so that the rack 57 is released and imparts to the cam 60 sufficient movement to trip the wheel 8. The forward movement of the rack is braked by a ball 63 held by a spring in a recess in the frame and engaging a wedge surface on the rack. In the forward movement of the rack a cam 68 on the detent 55 is engaged by a. roller 69 on the rack so that the link 54 is given a further lift to disengage the feeler pawl 22 from the ratchet disc 21. A finger 66 on the shaft 19 engages a pin 67 on the rack 57 to restore it into engagement with the detent 55. The feeler and its associated parts are returned to normal position by a spring 29. In a modification, the lever 25 is provided with a toothed sector in mesh with a pinion on the shaft of the subsidiary cam, and the shaft 19 is provided with a cam for returning these parts to normal position. In the modification shown in Fig. 7, the lever 25 is provided with a toothed sector 31 meshing with a gear wheel 42 on a shaft 41. on which is a loose arm 40 carrying a shaft 39 provided with a planet pinion 43 meshing with the wheel 42, and a cam 44 riding on a roller 46. The shaft 39 is connected by links 38 to an arm 37 carrying a roller 47 engaged by a cam 20 to give the normal lift to the friction wheel 8. The subsidiary cam 44 gives an upward roll to the planet pinion 43 so that the shaft 39 is raised and lifts the arm 37 to trip the wheel 8. Specification 159,154 is referred to.
