Abstract: 10,677. White, G., Baker, G. S., and Baker, G. R. July 22. Coating confectioners' goods.-Relates to chocolatecoating machines of the kind in which the centres are automatically fed to a cord or wire conveyer, on which they are automatically given bottom and top coatings. The centres slide down an adjustably inclined table 1, which receives an adjustable shaking movement laterally or transversely, to an endless travelling band 13 passing over a roller 14 at the rear or receiving end and a knife-edge 15 at the forward end. At the rear end, the centres pass first between wire spring loops 19, and later on between longer wire loops 20 to be alined, the loops being carried by an adjustable and removable frame 18 which receives a small transverse sliding movement. At the delivery end of the band, the centres are allowed to pass intermittently by means of fingers 28 and a rocking shaft 29, to a second band 31, travelling faster than the band 13 and passing around a roller 32 and an adjustable knifeedge 33 ; this band also receives a reciprocating motion. The centres, after passing other alining wire loops 34, are swept on to a plate 36 by brushes mounted on a transverse rod 46 and carried by a frame, to which a parallel motion is given alternately forwards in a lowered position and rearwards in a raised position. This motion is obtained by means of two cams 50, 51 acting upon arms 49, 52 connected as shown in Fig. 1 The plate 36 receives a longitudinally reciprocating motion by side rods 37 operated by cam mechanism from the shaft 29. The centres are swept off the plate by a fixed rod 44 as the plate 36 recedes, on to rollers 55 arranged in a jacketed tank 45 containing chocolate, whereby the centres receive a bottom coating. The centres are then passed on to a conveyer 57 formed of a continuous cord or wire passing over grooved rollers 56, 58, the arrangement being such that the cord passes in parallel relationship over each alternate groove, and is then returned around two other rollers 59, 60, the former of which is grooved and the latter takes up the slack, to the alternate grooves in the upper rollers, and then to the intermediate grooves so that the wires are parallel above but crossed below. The roller 59 is close to the cords above, so that the cords passing over it rub the cords.above for the purpose of removing excess chocolate from the centres. The driving-roller 58 is intermittently driven by interrupted gearing of known form. The centres are moved forwards by brushes connected. by a link 47 on a rod 48, which has two arms 49, 53, the former acted upon by a cam 50, and the latter connected to an arm 52 acted upon by another cam 51, the cams being so devised that the brushes receive a movement alternately horizontal close to the conveyer and in a parallel direction above it. A second similar conveyer 64 passes over the roller 58 and an adjustable slightly-grooved knife-edge 65, and beneath a vessel which delivers fluid chocolate to the tops of the centres. The chocolate is contained in a jacketed mixing-vessel 66, from which it is raised by a bucket pump to an upper reservoir 73, mounted so that it can be swung out of the way, and thence it is delivered through adjustable slots 91 in its base on the centres, which are still maintained in alinement by pins 92, 94 on transverse plates 93, 95. These plates are carried by rods 96 which receive both longitudinal and vertical movements. The cords of the conveyer receive a slight adjustable tapping movement. The coated goods may subsequently be given a decorative device on the top surface.
