Abstract: 359,093. Making wafer biscuits. ANTONELLI, D., Progress Works, Ayres Road, Old Trafford, Manchester. Aug. 7, 1930, No. 23632. Addition to 306,644, [Class 28 (i), Bread-making &c.]. [Class 28 (i).] Relates to a number of improvements in the machine for making ice-cream cone biscuits described in the parent Specification. The outer rails 1 of the run-way for supporting the mould units 2, instead of extending as in the parent case in a semicircle around each vertical shaft 3, extend only to points slightly beyond the shafts. The inner rails 4 abut against stationary curved flanges 5 partly encircling the shafts 3, thereby forming an endless track. The outer semicircular run-ways for supporting the outer ends of the cross-bars 6 of the core bars 7 during the transfer movement are also dispensed with, the outer ends of the bars 6 being supported by a hook connection 10, 11 with an oscillating radial arm 9. The inner ends of the mould units 2 are supported during the transfer, by the engagement of the rollers 2a with the track 5, whilst the outer ends are supported by a lower oscillating radial arm 12. To ensure that the bars 6 and the mould units 2 are engaged by the arms 9, 12, each arm carries jaws 13, 14 having bevelled faces which ride over and grip the bar 6 'and the flue cavity wall of the mould 2 and positively move the members. At the end of the swing the jaws are released for the return movements of the arms by the bevelled faces engaging the previously transferred bar 6 and mould 2. The bars 6 and the mould units 2 are prevented from moving backwards by pivoted hooks which engage the guide rods 25 of the bars 6 and the rollers 2a of the moulds 2. The mould units 2 are locked together by spring- pressed forked levers 27 which clip together contacting bevelled lugs 26 on the units 2, the levers 27 being disengaged from the lugs 26, to permit the transfer, by a cam 30a on the track 5, at the inner ends, and, at the outer ends, by a sliding spring- returned bar, actuated by the arm 12. The core bars 7 are connected to the cross bars 6 by compression springs 37 and are secured to the moulds 2 by pendant hooks 36b pivoted to the cross bars and engage - able with lugs on the moulds. The cross-bars are raised at both delivery points of the machine by vertically sliding bars 38 having flat heads 43, the bars 38 being operated by a roller 40 engaging an inclined cam-wav in a reciprocating block 41. The rollers 6a of the bars 6 first engage inclined brackets 39 which start the movement of the cores away from the moulds 2. The rollers 6a are then engaged by the heads 43 and the bars 6 are raised to the tracks 8 where they are secured to the arm 9 by the hook connection 10, 11 and the jaws 14. The cores are tilted during the raising motion, e.g. by the engagement of rollers 7a with a cam face, to facilitate the discharge of the cones. The vertically reciprocating rods 45 lower the cores on the bars 6 into the moulds at the end of the transfer, a lever system 47, 50 secured to each rod 45 cooperating with a fixed cam-slotted plate 44 whereby the supports 46 for the rollers 6a are positioned thereunder to support them, and withdrawn therefrom to release'them at appropriate times in the rising and falling movement of the rod 45. The rollers 6a are pressed down to compress the springs 37 and to seat the cores properly in the moulds preparatory to locking by the hooks 36b, by presser bars 53 pivoted to levers 54 on a cross shaft 55 which also carries a lever 56 having a roller 57 engaging a cam 58 on the shaft 3, the lever 56 being held against the arm by a compression spring. The hooks 36b are released, preparatory to raising the cores, by spring-pressed levers adjacent to the inclined brackets 39, the core bars being pressed down, to facilitate this, by pushers 61 connected to lever arms 62 on a cross shaft 63 having an arm 64 which is displaced by a roller or boss 65 on the radial arm 9. The moulds and cores may be heated as in the parent case, and the core bars may be fitted with gilled copper rods to increase the heating effect. As shown in Fig. 2, the batter is supplied at each end of the machine by a pivoted pipe 72 having nozzles 73, the pipes being oscillated by a slotted arm on one of the pipes engaging a pin 74 on a slide bar 75. The motion is communicated to the other pipe by an adjustable link 76.
