Said shaft 1115 has a bevelled pinion 146 thereon which meshes with a pinion 11T on a shaft 1/"8 journalled in boxes 14) mounted on 'trame member 35 (see Figs. 2 and 5),
said shaft 148 carrying a bevelled gear 150v meshing with a bevelled gear 151 on they vertical shaft 66 (see Figs. 1 and The movement of .shaft with cam roller 14st thereon oseillates lever 135 and thereby moves plates 127 and 128 out of the Way the upper carton when the same is being elevated by the suction mechanism, and moves said plates in engagement With said upper carton toY hold and guide the same during the dis-- clmrge-thereof, when the suction mechanism is beingl elevated and removed from said upper carton. The@ plates 12T and 128 with the levers 135 and associated mechanism are made and arranged to be adjustable so that they will be adapted to fit various Widths of cartons to be operated on and fed by the machine.
Means is provided for carrying away the upper carton when it is supported by plates 127 and 128, and this means` comprises a shoe 152 (see Figs. 1 and 13) provided en one of the links of a discharge chain 153 tJavelliun` over an idler sprocket 1511 which is rotatably mounted on shaft 1115, and said chain is driven by a sproeket 155 pinned to 156 journalled in the lower part ofv bearing.. 157 mounted on upright members 31 and 32. The shaft 156 carries a pinion 158 operating a gear 159 on a stud shaft 1GO journalled in the upper part of bearings 15.7 (see Figs. 1, 2 and 5). Shaft 1GO also carries a pini-on 161 meshing with a gear 162 mounted-on a stud shaft 163 journalled in fame member and carrying a bevelled gear 164i which meshes with the bevelled gear 165 fastened on vertical drive shaft 66. Said gears 165 to 158 step up or increase the speed of shaft 156 four times to the speed of vertical drive shaft 66, in order to provide a complete revolution or the proper length of travel to the chain 153 with its shoe 152 for dischargilig the top carton from the machine onto the track means 166 or any similar suitable means for receiving the discl'iarged carton.
T he main frame construction comprises four similar sections (see Figs, 6 and 8) including four supporting plates or platforms 63, each for supporting a stack of cartons thereon, as explained heretofore, and n'ieans for swinging this frame, when one stack of cartons has been fed, so as to bring the next stack of cartons and platform into feeding position. As shown in the drawings the present construction comprises four sections with supporting platforms 63, and the fran'ie is swung one-fourth turn when the platform which is in :feeding position, has been emptied and moved to its elevated position. The construction for rotating the 'frame coniprises the main shaft (see Figs. 3 and 8) which has a cam member 167 keyed to its lower end and provided with cam teeth on the upper surface which engage cani teeth on the lower surface of a gear 168 mounted to rotate with and to slide on said main shaft 56. The gear 168 meshes with and is actuated by a rack bar 169 which has a plate 170 Yfastened thereunder and being slidably supported on frame 30, said plate being held in position by guide slices 171. A link 172 (see Figs. 1, 6 and 7) is pivoted to said plate 17e and is driven by a crank arm 173 of a bell crank fastened on a shaft 17a joui-nailed in a bearing 175 mounted on vertical post 32, said shaft 174 being driven by a sprocket 176 and a chain 177 operating thereon and driven by a sprocket 178 fas'- ened on the outer flange 179 of a bushing 179 which is loosely mounted on the main drive shaft 445 at the upper part of the machine (see Figs. 1 and 18).
'lhe means provided for rotating the main 'frame with the carton platforms, includes a lug 18() on plate 170 fastened on rack bar 169 Fig. 7), said lug engaging a roller 181 at the end of lever 92 and operates said lever during the movement of the crank arm 173, to disconnect the bevelied gear 91 from gear 58, in'unediately before the swinging or rotating of the fran'ie, and holds said gears disconnected during the quarter turn Athereof. The rear part of rack 16S) operates a gear 182 see Figs. 3 and 7) mounted on a shaft 183 jonrnalled with its lower end in base 30 and with its upper end in a bearing bracket 184 extending up from the base.
The rearward n'ioveinent of rack bar 169, or its moven'ient to the left-hand side as seen in Fig. 7, turns the cams on the lower end of gear 168 (see Figs. 3 and 8) idly over the cams on the upper face of member 167 and does not turnthe vertical shaft 50 or the iframe, but upon the forward movement of ic rack bar, or the movement toward the ght as indicated by arrow a in Fig. 7,
he cams on the lower face of gear 168 ,bitches and operates the cams on member 167 and therewith rotates the attached main supportinn` shaft 5() and the frame sections and platforms 63 supported thereon, 'for one quarter revolution in clock-wise direction, thus bringing the next platform into discharging position toward the forward part the machine, or the right-hand part as seen in Figs. 3 and 7; during which time gear 182 has moved lever 188 (see Figs. 3 and 7) by means of the lug 186 on disc 185, and thereby has withdrawn the brake shoe '193 from its holding or locking position between the triangular frame members 53; and at the same time the lug 180 on plate 170 or rack bar y169 has actuated lever 92 and has thereby withdrawn bevelled gear 91 from gear 58, thus freely permitting the turning of the 'frame with the carton supporting platforms.
'1` he means 'for automatically actuating the above frame turning mechanism comprises lugs 196 (see Figs. 1, 6, 8 and 13) at'the sides of plates or platforms 63, and these lugs, when the platforms are in their extreme upper position engage and operate a roller 197 mounted in the lower end of a bent rod 198 which is made adjustable by means of a screw-sleeve 199 and which has its upper end attached to a lever 206 (see especially l*l 1 and 18) :fulcrumed on a pivot stud 201. provided on bracket member k12. Each triangular 'frame 52 is notched at the upper corner edges 197 to permit the roller 197 to pass freely above the same during the rotation of the frame and carton supporting mechanism. By elevating the rod 198 the lever 200 is swung so as to re-
