Abstract

315,692. Camco (Machinery), Ltd., (Assignees of Tufts, L. R., and Olson, A.). July 16, 1928, [Convention date]. Delivery apparatus.- Paper sheets being delivered from a machine such as a folding-machine 10 are deflected by means of a member 43 to different delivery points, and each sheet after leaving the deflector 43 engages a detector device associated with its own delivery mechanism so as to set the deflector for directing the succeeding sheet to another delivery mechanism. A sheet A passing over the upper side of the deflector 43 is forwarded by a steel roll 36 and rubber wheels 35 to an endless stacker-band 71 moving parallel to the direction of delivery. Pivotally-mounted on an arm 58 adjustable by a set-screw 54 and spring 53 is a swinging-shoe 45 the end of which normally projects between the roll 36 and wheels 35 so that the front edge of the sheet A forces it backwardly. A similar arrangement of steel roll 38, rubber wheels 40, adjustable arm 61, and swinging shoe 46 is arranged below the rolls 38, 40 so as to forward a sheet which passes below the deflector 43 on to an endless stacker band 74 moving at right-angles to the direction of delivery from the machine 10. The shoes 45, 46 are coupled together by cranks 58, 66 and a connecting-link 67, and an extension 68 of the crank 66 is connected by a link 69 to a crank 70 on the spindle 44 of the deflector 43. The backward movement of the shoe 45 caused by the sheet A therefore causes the deflector 43 to be rotated into position for deflecting the succeeding sheet on to the band 74, and so as to reset the shoe 46 for engagement by this sheet. In a modified construction, the, cranks 68, 70 and link 69 are dispensed with, and electric contacts on the link 67 are adapted to connect up electric circuits containing electromagnets which operate the deflector 43, such operation in this case being independent of the force excited by the sheet on the shoe 45 or 46. The delivery mechanism is arranged as a separate entity in a frame 22 and is geared to the delivery rolls 14 of the folding machine by means of an idler gearwheel coupling the rolls 14 to the rolls 27 feeding the sheet into the delivery mechanism. Specification 308,352 is referred to.
