Abstract: 329,362. Wootton, E., and Jones, W. F. Jan. 18, 1929. Waffle and like baking- apparatus; hot plates; baking-trays and like, greasing. -A machine for making crumpets, cakes, and confections comprises a revolv. ing hot plate on which mould rings are deposited, a hopper which deposits batter or the like into the moulds, means for removing the moulds from the partially cooked contents and for turning over the solid contents, and means for removing the cooked articles from the hot plate. The moulds, when removed from the hot plate, are passed to a greaser and are then returned to the hot plate to receive another charge. As shown, the hot plate 1 is rotated intermittently by a cam-operated ratcnet 130 and is heated by gas or electric heaters 6. The batter hopper 5 is removably supported in memoers 8 and has an outlet 10 controlled by a valve 11 discharging into a spreading member 12, which is funnel-shaped and is revoluble by gearing 19 - - 23 and cam mechanism. The spreader 12 discharges its contents, during its rotation, in ribbon form around the walls of the mould rings, the ribbon being formed by an elongated orifice 14 closed, at times, by a spring-actuated cutter 15, which is opened during the rotation of the spreader by a stop 16 thereon contacting with a stop on the machine frame. The cutter 15 has screw-adjusted means which determines the amount of batter deposited. The mould rings slide down a shoot 26 from the greaser and are positioned and held temporarily on the hot plate by a stop 27, having fingers for holding the ring, formed on a rod 28, which is actuated by a cam to withdraw the stop from the rings when the deposition of batter has been effected. When a charged mould ring has made about four-fifths of a revolution with the hot plate, an arm 32 with gripping fingers 47 at its end, is swung down on to the. ring 67 and then lilts it from the hot plate leaving the crumpet to be turned on the hot plate as described below. The fingers 47 are shaped so that on being moved downwards on to the ring they are moved outwards to grip the flanged upper edge of the ring, springs 48 maintaining the gripping pressure. The arm is mounted on a knuckle joint 34 and is swung up and down by a rod 35 actuated by a cam 38, spring 39, rod 37, and bell crank 36. The lever is swung transversely, to deposit the rings in the greaser 50, by a member 42 which is bifurcated to engage the arm 32, and is carried on a shalt 40 which is oscillated by a rod 44, cam 38, and spring 45. When the ring 67 is positioned over the greaser, the arm 32 is swung downwards and the fingers 47 are released from the ring by engaging the head 52, Fig. 6, the ring being deposited on a hinged plate or flipper 69 having a central opening 70. The head 52 is carried on a rotating shaft 53, which is reciprocated axially by a rocker arm 59 actuated by the cam 38. The ring is gripped by spring-secured fingers 61 which are projected inwardly by the upward movement of the shaft 53 actuating members 62, 64 through a wedge-shaped cam 66 carried by the shaft. The brush 51 which is greased in the tank 50 rises with the shaft 53 and greases the ring. The shaft 53 then descends and the flipper plate 69 is swung, by a link 71 operated by the shaft 53, to deposit the rings on the shoot. The crumpet is turned by a flipper 80, Fig. 12, comprising a thin metal plate lying close to the hot plate and pivoted in a bracket on the machine frame. The plate is actuated by a rod 82, cam 83, bell-crank 84, 86, rod 87, quadrant 89, and a pinion 90 on the pivot. The crumpet is pushed up on to the plate 80 and is swung thereby, in the reverse position, into an inner circle on the hot plate. The cooked crumpets are removed from the hot plate to a receptacle by a conveyer 102, the part of which adjacent to the hot plate is trained over a small roller, the articles passing over an inclined guide plate, in front of the roller, on to the conveyer 102.
