Abstract: 415,533. Packeting - machines. BUREN, J. VAN, 750, Grand Street, Brooklyn, New York, U.S.A. May 3, 1933, No. 12925. [Class 94 (i).] In a machine for stacking articles for boxing, a movable carrier is adapted, in one position, to be loaded with a plurality of series of articles, and, in another position, to be discharged, a single control element operable by the plurality of series of articles in a packet controlling the movement of the carrier and the discharge of the articles. The articles to be stacked are fed into the machine on two conveyers 21, 22, Fig. 1, and arrive in rows on plates 46 on each side of an open-sided pocket D, then in a horizontal position. When a predetermined number have been fed, they are pushed laterally into the pocket in succession from opposite sides. The right-hand packet X<1>, Fig. 16, forces a plate 95 to the right against the action of a spring 93<1>, carrying with it an abutment 86 which is taken out of alignment with a cam rail 85. Mounted on slide rods 65, Fig. 13, is a reciprocating block 64 having pivoted thereto a pusher plate 60 held in the raised position shown when the parts 85, 86 are in alignment. When the abutment 86 is displaced by the arrival of a correct load on the plate 46 the pusher plate drops into position to engage the row of packets, and, on the next reciprocation to the right of the block 64, the packets are fed into the pocket D, and, subsequently, another row is fed from the opposite side in a similar manner. Upon the block 64 being retracted a roller 71 associated with the plate 60 rides up a pivoted incline 88 to the cam rail 85. The incline 88 is resiliently mounted so as to yield when the plate 60 makes its working stroke. The pocket D is one of a series of four mounted for intermittent rotation on an axis 51, and, upon being fully charged, is turned up into the vertical position occupied by the previous pocket. The pocket cannot be turned until two complete rows of packets have been inserted. In order to ensure this, a block 140, Fig. 8, is pivoted at 139 on a slide 137 adjacent to the open end of the pocket in its loading position. When one row of packets X is inserted, as shown in Fig. 8, the block is turned about its pivot. Upon the other row being inserted, the part 141 of the block pivots about the part 142 to move the slide 137 to rock a shaft 126, thereby allowing a clutch lever 120 to connect shaft 110, Fig. 1, to the main drive and to rotate shaft 51 through 90‹ through Geneva-stop mechanism160-163. The stack of packets is pushed out of the topmost pocket by a plunger 165 on to a plate 166. A plunger 195, Figs.1 and 4, operating at right angles to the plunger 165, pushes the stack into a carton 219. A guide 217 with a recess 218 serves to accommodate the front lower edge of the carton and the corresponding flap 221 which has been turned up underneath, the front surface 215 sloping to assist the insertion of the packets. The plungers 165, 195 are operated in proper timed relationship from the shaft 110, and their movements are thus dependent upon the supply of series of packages.
