Cartons folded by the folding means within the housing 12 are conveyed between the guide plates This invention relates to paper carton folding appara 16 and 13 toward the aperture 14 by frictional engage tus, and more particularly, to an apparatus for automatical ment between the bottom wall on the carton and the ly manipulating a partition wall in a carton prior to the 10 chain 24. step of ?lling the carton with material. A means 26 is provided for manipulating a partition wall on the carton just prior to the discharge of the carton Heretofore, it has been conventional in the art to man ually place a partition wall in a carton designed to have through the outlet aperture 14. As shown more clearly a plurality of goods separated from one another by a parti in FIGURE 2, such means includes a O-shaped bearing tion. The manual positioning of such a partition wall 15 block ?xedly secured to the upper surface of the ?oor plate 19. The bearing block 28 is provided with aligned is time consuming, expensive, and affects the production apertures 39 and 32. in its horizontally disposed arms. rate of ?lling cartons which material. I have discovered An upright shaft 34 is rotatably supported within the that the use of separate partitions can be eliminated by apertures 31} and 32. making a partition integral at one end with a side wall A ?nger 36 is adjustably secured to the shaft 34 at a of the carton. The present invention is directed to an 20 point intermediate the arms on the C-shaped bearing apparatus which automatically manipulates the partition block As shown more clearly in FIGURES 3-5, the wall out of the plane of the side wall of the carton and end of the ?nger 36 remote from the shaft 34 is semi locates the same in a position extending between the side circular in plan view. The ?nger 36 extends through an walls of the carton. It is an object of the present invention to provide a 25 aperture 38 in the guide plate 16. The uppermost end of the ‘shaft 34» is provided with e" novel apparatus which eliminates the necessity for man ternal threads 49. A lock nut 42 is threadingly engaged ually placing partition walls in a carton. with the threads 1513. A torsion spring 44 extends be tween the bearing block 23 and the lock nut 42. As shown more clearly in FiGURE 2, one end of the spring 12-4 is ?xedly secured to the lock nut 42 and the other end of the spring 44 is ?xedly secured to the bearing block 28. The carton with which the ?nger 36 is adapted to co operate is shown more clearly in FIGURE 6 and is designated generally as 45. A side Wall of the carton 46 It is another object of the present invention to provide a novel apparatus for manipulating a partition wall out of the plane of a side wall of a carton and disposing the same in a position extending between the side walls of the carton. t is another object of the present invention to provide a novel apparatus which is capable of cooperating with car tons as they proceed along a conveyor belt so as to auto matically provide the cartons with a partition wall. It is still another object of the present invention to pro vide an apparatus which is simple and economical while capable of materially reducing the cost of a partition wall for a carton and materially increasing the rate at which such cartons may be ?lled with material. Other objects will appear hereinafter. For the purpose of illustrating the invention there is ‘shown in the drawings a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown. is provided with a >U-shaped slit. A score line 59 extends across the free ends of the U-shaped slit at a point equi distant from the ends of the carton 46. The remaining elements not yet speci?cally described are more conveniently explained in conjunction with the manner in which the present invention is utilized. As the cartons 46 are folded by a folding means with in the housing 1.12, such cartons are conveyed to the out let aperture 14 between the guide plates 16 and T.“ by the chain 24. Suitable positioning means (not shown) may be provided to assure that the cartons 46 are juxtaposed to the guide plate 18 as shown more clearly in FIGURE ,0’ FIGURE 1 is a partial perspective view of a box fold 3. ing apparatus containing the present invention. As the carton 46 approaches the end of the guide FiGURE 2 is an elevational view of the rotatable shaft 50 plates 16 and 18, the ?nger 36 is in the position shown in FIGURE 3. and ?nger of the present invention. As the carton 46 passes by the ?nger 36, the rounded end of the ?nger 35 presses against the side wall 51 of the carton 46. Since the side wall 51 is provided with FIGURE 3 is a partial plan view showing the struc tural interrelationship between the manipulating ?nger of the present invention and one position of a carton being conveyed past the ?nger. 55 FIGURE 4 is a partial plan view similar to FIGURE 3 showing another position of the carton and the manner in which the ?nger cooperates therewith. FIGURE 5 is a partial plan view similar to FIGURES 3 and 4 showing another position of the carton and the manner in which the ?nger cooperates therewith. FIGURE 6 is a perspective view of the carton adapted to cooperate with the ?nger as shown in FIGURES 3-5. Referring to the drawing in detail, wherein like nu merals indicate like elements, there is shown in FIGURE 1 a carton folding apparatus designated generally as 10. The apparatus 10 includes a housing 12 within which is disposed means for folding blanks into a carton of the type shown in FIGURE 6. Such means forms no part of the present invention and therefore need not be shown or described in detail. The housing 12 is provided with an outlet aperture 14 a uashaped slit, the ?nger 36 readily pushes the partition wall 48 inwardly as shown more clearly in FIGURE 4. As the partition wall 48 is moved to the position shown in FIGURE 4, the partition wall 43 pivots about the score line 59. As the carton 46 continues in its movement past the ?nger 36, the portion of the wall 51 adjacent the score line 50 contacts the ?nger and rotates the same against the bias of the spring 4-4. That is, the ?nger 36 rotates in a clockwise direction in FiGURES 4 and 5 until the ?nger assumes the position shown in FIGURE 5. It will be understood that the spring 44 is weak enough so that the wall 51 adjacent the score line St} is not torn by con tact with the ?nger 36. As the carton 46 continues to move under the influence of the chain 24, the rounded end of the ?nger 36 presses against the side wall 51 until the ?nger 36 clears the end 52 of the carton 46. Thereafter, the ?nger 36 rotates in 3,083,819 4 3 as the partition w=all48r As shown more clearly in FIG ‘a counter clockwise direction to the position shown in FIGURE 3 due to the bias of the torsion spring 44. As shown more clearly in FIGURES 4 and 5, the move ment of the partition" wall 48 out of‘the planeof'th'e'side wall‘ 51 results in the provision of a rectangular aperture 541having dimensions corresponding with the dimensions of, the partition wall 48. It‘will be noted that the length of the partition wall 48 ‘corresponds to the distance be tween the side walls of the carton 46. Su?cient details of URE 2, the vertical disposition of the ?nger 36 may be adjusted so as to accommodate di?erent sized cartons and/or locations of the partition wall 48. The present invention may be embodied in other spe ci?c forms Without departing-from'the spirit or essential attributes thereof and, accordingly, reference should be i made to the appended claims, rather than to the foregoing speci?cation as indicating the scope of the invention. th'ebox 46 havebeen disclosed so as to understandthe 10 I claim: ‘ ' 1.
