182,863. Antonelli, D. March 12, 1921. Wafer biscuits, a cone wafer moulding and baking machine a charge of batter is confined in a closed mould which is of greater volume than the charge, but is reduced during the baking operation to the final capacity and form desired. The apparatus embodying this method of operation comprises special means for heating, for ejecting the baked product and other features. A number of moulds are used the male and female parts 62, 35, Fig. 2, being mounted on interconnected members 18, 24 which are simultaneously moved towards or away from one another, the lower member 24 being tilted into a substantially vertical position, Fig. 5, after separation of the mould parts, to facilitate removal of the cones. The bottoms of the parts 35 are formed in sliding members 36, Figs. 2, 5, which are actuated to rise after closing of the moulds thereby reducing the mould space during baking, and are retracted and again pushed forward partially to eject the'cones during the withdrawal and tilting of the member 24. The batter supply is effected by pivotally-mounted valve chambers 92, Figs. 4 and 8, which are positioned over the moulds when they are open and retracted prior to closing. The parts 18, 24, which are pivoted at 19, 25 to gear-connected, cranked levers 16, 17 and 22, 23 respectively, balance one another in any position and are operated by a handle 28. The levers 16, 17 are secured to a shaft 15 and the levers 22, 23 revolve on a shaft 26. The position of the point of suspension 25 ensures the member 24 keeping horizontal during the first stage of the opening of the moulds, the member 24 then being tilted by rods 29, pivoted to the member 24, passing through bosses 30 on the member 18 and provided with nuts 31 and springs 32. On the descent of the member 24 the nuts 31 compress the springs 32 and throw the member 24 into the position shown in Fig. 5, the member 18 being also slightly tilted. Stops 33 contact with the rods 29 when the member 24 is horizontal. The members 36, Fig. 2, are secured to a plate 38 having burner orifices 39, the plate 38 forming, with a plate 41, a chamber 40 to which gas and air are supplied by a flexible pipe 43 connected to a mixer. The chamber 4C is carried by sliding side members 49 supported by rollers 50 which engage cam surfaces 51 on levers 52 pivoted to the levers 22, 23 and actuated by cams 55 secured to the shaft 26. The shaft 26 carries a weighted arm 66 and is oper. ated by levers 69, 70, 71, the lever 71 being pivoted at 15 and having adjusting-bolts 74, 75 which contact with stops 72, 73 on the lever 17. On opening the mould the weighted arm 66 is raised, and the members 36 are actuated as stated above. The descent of the arm 66 is controlled by a rod 76 which projects through the plunger 78 of a dash pot 77, a cone 79 forming the valve and free upward movement of the rod being limited by a nut 80. A vent may be pro. vided in the plunger body or the side of the cone 79 may be grooved. The combustion products pass through vents 56 to a chamber 58 and from thence through regulable vents 60 to a hood 102 connected with a flue. The parts 62 are provided with shanks 64 having heat-absorbing flanges, Fig. 2, and with cylindrical heads 63 situated below the bottom plate of the chamber 59 and adapted to enter the recessed upper portions of the parts 35. The shanks 64 pass though the plate 59 and are slightly movable laterally to ensure engagement of the mould parts 62, 35 which is facilitated by slight chamfers on the parts 35. The batter supplying device is carried by brackets 81 having curved tracks 82 on which are carried rollers 88 on levers 85. The levers 85 together with levers 86 are pivoted to cross-heads 84 slidable on rods 83 and are connected at their upper ends with a bracket 87 carrying the valve chambers 92. The tracks 82 are shaped so that a straight-line motion is imparted to the chambers 92 during advancing to and withdrawal from the operative position. and indentations 82<1> are provided to retain the rollers in the extreme positions. The chambers 92 are connected to a header 89, connected to the batter mixer by a pipe 90, and contain rotary members 93, Fig. 8, having pockets 94 which register with ports 95, 96. The pockets 94 are filled when in the position shown in Fig. 8; the batter being deposited into the parts 35 when the chambers 92 are positioned and the member 93 rotated. The members 93 are interconnected by gear wheels 98 and a sliding rack 99, and the capacities of the pockets 94 may be varied by screws 97.
