Abstract: 11,700. Armstrong, H. Y. June 7. Parcelling confectionery or sweetmeats &c.-Relates to machinery for cutting strips of candy caramel or similar plastic substances into blocks or cubes and then wrapping these up in paper. Referring to Figs. 1 and 5, the strip is passed between guides v to a pair of toothed feed-wheels e, the shafts of which gear by wheels i, one of which carries a ratchet-wheel j engaged by a pawl l pivoted on a lever k. The pawl is held in or out of operation by a spring m, and is set in either position by means of a handle o on its pivot pin. The lever k is vibrated from a main shaft p by means of a link s and a lever r carrying rolls straddling a camplate u. The position of the strip is limited by a stop on brackets x. The shafts of the feed-wheels are adjustably mounted in brackets, one of which has a lug with a threaded bore for a right and left hand screw 116 engaging the framing. A cutting- blade v is detachably secured to a bar z, which is linked to the angle-plate c and operated by the engagement of a roll on its end with a grooved cam 31 on the shaft p. A steadying-rod 111 is pivoted to the bar z and passes through a pivoted block 112, between which and the lower part of the rod a spring 113 is interposed. A stripper-bar is provided. The cut cube is brought to the proper size by forcing it by means of a plunger 52 between projections on levers 59, which are held inwards by a spring 60 and limited outwards by the brackets x. Paper is fed under the cube, and both are forced by the plunger 52 into one of several pockets 36, Figs. 5 and 6, of a head 34 mounted on a shaft 35. One side of each pocket 36 is formed of a spring 37. The shaft 35 receives a step-by-step motion from the shaft p by means of a gear plate 103, Fig. 1, provided with alternate slots 104 and concavities 105, and a disc 107 with a raw-hide gear tooth or roll 106 engaging the slots and a raw-hide stop disc 108 having a concavity adjacent to the tooth 106 and the remaining periphery convex or circular to engage in the concavities 105. The paper is fed from a roll mounted in a wheel and passes over a guide 39, Figs. 5 and 6. A pinching-finger is mounted on a bell-crank lever 40, in one position of which the finger grasps the paper and prevents its withdrawal, and in another position the finger is raised to allow forward feed of the paper. A feed-lever 42 supported on the shaft 35 carries a pinching-lever 43 with a pair of rolls arranged to grasp an arm 46 of the lever 40. A projecting arm of the lever 42 carries a pinching-finger on a rock-shaft 51. A spring is also provided on the guide 39 to hold the strip against the bed of the angle-plate c. The lever 42 is connected to the rod 100 of an eccentric 99 on the shaft p. The plunger 52 is reciprocated by an eccentric 56 on the shaft p. The paper strip is cut by a device comprising a fixed and a pivoted blade on a sliding block moving in a slotted bracket 62, Fig. 1. A pin on a dog 64 pivoted on the block engages a notch in the pivoted blade, and is released by contact with a stop 65 to permit a spring 66 to operate the blade. The sliding block is secured by a screw stud to the end of the lever r. The forcing of the cube and strip into the holder and cutting of the strip leaves the package with the first fold. The second fold is made by a roller 72, Fig. 6, on a flexible lever 71 on a rockshaft 70 operated by an arm 73 on the main shaft p. The third fold is made by a finger 75 on a lever 76 pivoted on the framing and held against movement by a link 78. The fourth fold is made by a pair of fingers 80, Figs. 5 and 6, pivoted on an L-shaped lever 81 operated by the eccentric 56. Cam portions on the fingers come in contact with a lug 83 on the lever 76 and force out the fingers against the tension of a spring. The fifth fold is made by a pair of fixed fingers 85 on the lever 81. The sixth fold is made by side plates 86. The last fold is made by a pair of horned fingers 87 pivoted to the framing, on which a receiving-channel 97 is mounted. A pair of L- shaped ejecting levers 91 are mounted on a rock-shaft 94 linked to the lever 42.
