Abstract: 666,634. Machines for cutting candy. MARS, Inc. May 10, 1948 [July 21, 1947], No. 12773/48. Class 87 (ii) A machine for cutting into bars strips of candy travelling in the direction of their length comprises a knife arranged across the strips and oscillated in the direction of its length while being reciprocated vertically to make the cutting strokes and being moved forward with the strips during cutting, the oscillation of the knife being produced by power means independent of the power means producing the other motions of the knife. As described, two knives are arranged one above the other to cut sets of parallel strips of candy on two different levels. Each knife 96, Fig. 2, is pivotally mounted at its ends on the lower ends of a two-armed lever 99 and a three-armed lever 94 which are in turn pivoted at 98, 100 to plates 34 sliding in guides 33, Fig. 1, on the vertical legs 30 of an inverted U frame 29 spanning the base of the machine. The upper ends of the levers 94, 99 are pivotally connected to tie rods 97 which are adjustable in length to adjust the tension in the knives. The third arms of the levers 94 are connected to bell-crank lever 91 which embraces an eccentric on a shaft. running in bearings 80 and rotated through a flexible drive 82 by a motor 89. The knives are thus oscillated in their length to give a slicing action. The frame 29 has four feet 31 with slides 32 working in guides 28 in the bed frame 25 of the machine. The plates 34 at their lower ends have bosses 35 engaged in slots in levers 38 and levers 49, the other ends of the levers being secured to shafts 37, 48 mounted in brackets 36 at each side of the machine, Fig. 7. The shafts 37, 48 also have keyed to them levers 55, 52, Fig. 8, the other ends of these levers carrying rollers 54, 51 working in cam grooves 47, 46 on a shaft cam 45 fixed to a shaft 39. The shaft is driven from a motor driven chain 41 and sprocket 40 through a slipping clutch 57, 59 the driven member 59 of which (fast on the shaft 39) can be stopped by a catch 61 on the member 59 engaging with a nose 64 on a lever 62. The nose 64 can be withdrawn from the catch by a hand lever 71. Vertical and longitudinal reciprocations, the latter in the line of the candy strips, can thus be given to the knives 96, the cam grooves 46, 47 being designed to give the desired motions. The candy strips 134 are fed to the knives bv a plurality of narrow conveyer belts 117, Fig. 5, guided by idle rollers 111, 114, 115, 116 mounted on the side members 108 of a fixed frame 105, Fig. 1, and idle rollers 112, 113 mounted on the legs 30 of the sliding frame 29. The belts are driven by a friction roller 118 on a shaft 119 mounted on the plates 108. The cut bars are removed by similar belts on the far side of the knives, guided and driven similarly, a guide bar 112a however replacing roller 112. The rollers 118 in shafts 119 are driven by chains 121, 123, Fig. 2, passing over chain wheels 122, 120 on the shafts 119 from a sprocket 125, Figs. 1 and 7, mounted on the brackets 36 and driven from a suitable motor. The chain wheels 122 on the delivery side of the knives are smaller than those on the feeding side to remove the cut bars at a faster rate with a gap between each. Guide bars 136 may be provided for the candy strips on the upper rim. The strips are held down on the feeding belts 117 by a roller 153 pivoted at 155 to members secured to the frame 29, and the cut bars are held down on the delivery belts by shoes 147 freely pivoted to levers 145 and raised about axis 146, which is fixed to the fixed frame 105, as the frame 29 is retracted, by a cammed block 148 engaging a cam follower 152 fixed with respect to the levers 145, the cammed block 148 being fixed to a guard bar 140. A guard bar 140 is fixed in either side of each cavity 96 and includes a plurality of downwardly projecting spacer members 141, Fig. 2, which maintain the candy strips in their proper locations.
