Abstract: 264,839. Bates, J. H. Jan. 22. 1926, [Convention date]. Wafer biscuits, making.- In a machine for making wafer cups, cones, and the like, the cooked articles are automatically removed from the cooking-moulds or plates by means adapted to engage the articles when the plates are open, and to remove them to a point of discharge. As shown in Fig. 1, the removing-means comprises resilient fingers 43 arranged in sets of three pivotally mounted on transfer mechanism, described below, whereby the fingers are inserted into the baked cones and are removed, with the cones thereon, to the discharge point. The socket moulds 17 comprise pivoted half mould members, Fig. 7, carried in a box 16 the top plate of which has tapered recesses to receive the upper rims of the moulds 17 when in the closed position as shown in Fig. 1. The mould halves are separated, after the removal of the plug moulds, by raising them relatively to the box 16 when pins 68 engage tapered openings in the side walls of the socket moulds, the halves being caused to pivot on axes 19 which are carried by aT-shaped member 20 actuated, as described below, by a. lever 60 and rod 62. Eight mould sets are arranged around a drum, formed by spaced side walls 8, Fig. 2, which is rotated intermittently by a roller 25 on a worm wheel 3 carried by a shaft 4, the roller 25 engaging slots 26 in a disc 24 secured to the drum axle 11. The drum is moved through oneeighth of a revolution whilst the roller 25 enters a slot 26, moves the disc 24 and leaves the slot. The plug moulds are carried on a member 27 pivoted at 28 on brackets 10 projecting from one of the plates 8, the member 28 being raised by a member 30 also pivoted at 28 and connected by a rod 36 to a crank 34 on a shaft carrying a toothed quadrant 35<x> engaging a vertically sliding rack 37 operated through levers by a cam 6. A fitting 32 on the member 27 engages a groove in the member 30 thereby coupling the members 27, 30 simultaneously with the disengagement of the locking trip 33 by the usual means. The removing-fingers 43 are fixed on a plate 44 carried by two Levers 45 having quadrants 47 which are engaged by a common quadrant 48 on a shaft 49 rocked by a cam 5 on the shaft 4 by levers, links &c. 50, 52, 55, 57. The carrier plate 44 is thus alternately positioned over the socket moulds and over the discharge point, and an arm 63 on a shaft 64 rocked by a crank 67, rods 65, 66 and a cam on the shaft 4, depresses the rod 62 and raises the cross-head 20 with the mould halves thereon which latter are thus separated for the removal of the cones. The cones are freed from the fingers 43 by a relieving-plate 70 which is pressed down by a lever 73 which is pivoted to the carrier plate 44 and has a stop bolt 76 which engages a stop 75. The depression of the plate 70 closes the fingers together and frees the cones. The return of the plate 70 is effected by springs 71. The batter charger 80, which is itself of known kind, is carried on pivoted arms 81 having quadrants 83 engaging with a common quadrant 84 on a shaft 85, an arm 88, adjustable on the quadrant, being oscillated by a rod 87, lever 86 and a cam 7 on the shaft 4. The interior of the mould frame is heated by a burner or burners 90, the gas being supplied through the journal 13 The plates 8 have vent holes for the combustion products. Vents for the escape of vapour or steam are provided in the top of the mould box 16 and in the member 27. The box is provided with internal ribs to form elongated spaces within which the moulds 17 are disposed.
