Abstract: 613,271. Newspaper-stuffing machines. SHERIDAN CO., T. W. & C. B. June 14, 1946, 'No. 17932. Convention date. April 2, 1945. [Class 100(i)] A machine for stuffing newspapers by inserting inner sections into a folded jacket is constructed with a number of containers 20 arranged in a circular path, and the jacket sections A are arranged in the first container. and the inner sections B in the other containers. A rotary member 51 is rotated about the circular path, and this carries a large number of U-shaped pockets 89, Fig. 12, formed of sections 90. 91, which are pivoted about a suction tube 88 and which in Position 1, Figs. 1 and 12, are arranged with the movable section 91 in the open position ready to receive a cover section A which is separated in known manner from a magazine 20 by means of an Oscillating suction separator 24, a gripper cylinder 25, a forwarding roller 35 carried on an oscillating arm, and a sheet guide 39. The cover section is fed with its folded edge downwards, and as the packet 89 travels towards Position 2 a pivoted arm 104 in which it is mounted is moved by a cam 118 so as to swing the section 91 towards the section 90 and the inner section A<3>of the cover is caused to be held to the section 90 by contact with a sucker 124, Fig. 5, arranged in an aperture 96 in section 90, and an additional holding device consisting of a pivoted hook member 139 actuated by stops 141, 143 may also be used. The stop 143 releases the hook at the same time as the suction holding device is vented. A projection 100 on section 91 assists to press the cover against the suction device, and a brush 98 may insure the opening out of the cover as the section returns to Position 3. As the pocket 89 passes under the magazines containing the carrier paper sections B these are fed into the opened-out cover, and as many as seven sections B may be inserted into one cover. When Position 4,is reached the complete product is delivered to a delivery device such as a band 121, Fig. 1. by opening out the section 91 about a pivot 103, which connects it to its carrying arm 104, and the product falls by gravity upon the band 121. The rotor 51 is built up of twelve sectors secured together and each fitted with five pockets 89 arranged side by side. It rotates on ball bearings about a fixed upright 45 which supports an upper framework which together with uprights 30 support rods 28 in which the gripper r cylinders 25 are mounted. The rotor 51 is driven by a motor 85, gearing 84, 83 and an adjustable coupling, and a circular track 72 carried by the rotor drives gears 31 on the shafts 26 of the gripper cylinders. The suction-cups 128, Fig. 11, which hold the cover sections A<6> open are connected by tubes 132 to a suction manifold formed of a fixed ring 145 connected by a tube 144 to a source of suction, and a ring 146 which rotates with the rotor. The inward motion of suction cap 128 opens a valve 136 to connect the cup to the source of vacuum. This valve tends to close under action of a spring 138, but when the cup is moved inwards the valve is retained open by the air pressure until the suction cup is vented. The construction may be modified slightly in various ways such as: (a) the cam 118 may be replaced by a box cam; (b) the drums 26 may be driven by a relativelysmall gear; and the inner section B may be fed alternatively from a pair of adjacent hoppers 20, so that with an arrangement including six hoppers 20 for the inner sections each outer cover section would receive three inner sections.
