Abstract: 134,641. Lewison, L. Nov. 19, 1918. Pastry; waffle and like making and baking apparatus.-An entirely automatic machine for forming and cooking edible ice-cream cones consists of a frame 1 having a central standard 2 with an upward extension 3 on and around which a circular rotary carrier 4 is driven intermittingly from a main shaft 5, by a pinion 6, spur-wheel 7, worm cam 9, and a series of projections 10, Fig. 3, arranged in a circular path beneath the carrier. The inclined part 11 of the cam is about one-fourth of the whole circumference of the cam, and is thickened at the part 75 so as to fill the space between two of the projections 10, whereby the carrier is brought absolutely to rest after each forward movement. The cones are formed in two-part moulds 13 into which cores 20 are depressed. The two parts of each set of cones are carried on arms 14 provided at their ends with interengaging hinge-knuckles 15 embraced by a bracket 16 secured to the carrier by a screw. A hinge-pin 18 passes through the bracket, the knuckles, and the carrier, and is extended upwards, as shown in Fig. 2, passing through a longitudinal slot 23 in the core arm 21, which is hinged on lugs formed on the bracket 16. To the pin 18 are attached one end of one or more springs 24, the other ends of which are secured tc the arm 21. The pin 18 also supports the locking-means 25, having rollers or the like 26, 28 at either end. A cam 31 is fixed on the journal 3, and a roller 32 on the heel of each core arm 21 engages under it to raise the cores at the desired times. Another cam 65, also fixed to the journal, engages the roller 32 on its underside and presses the cone firmly down into the mould, where it is locked bv means of an arm 27 attached to the core arm, being engaged by the roller 26 on the lever 25, this lever having been moved over by means of a cam 29, Fig. 1. Another cam 30 acting on the roller 28 on the other end of the lever 25 releases the arm 27 and thereby unlocks the core. The two parts of the moulds are normally pressed together by bent springs 35 arranged between each set of moulds, and are opened by a cam 41, Fig. 3, beneath the carrier engaging a projection 40 on a vertical rod 38 passing between the two arms of each set of cores, and having a cross-bar 39 which, when the rod 38 is turned, forces the two arms apart, as shown in Fig. 1. When closed, the two parts of each mould are securely locked together by means of a fixed cam 45 engaging above a roller 46 on a hooked-shaped lock 43, Fig. 6, pivoted to one part of the mould, and forcing it over a pin 44 on the other part. If there is any obstruction, the cam 45 will pass below the rollers 46 and the lock will not be operated. The projection 47 on the lock actuates the batter-feeding device, by engaging dogs 61, Fig. 34, on the end of the rotary inner valve part 49, Fig. 29, thereof. This inner part is divided into sections 59, each having one opening 60, the outer fixed casing having two openings, one 57 under the batter hopper 58, the other 58 allowing the contents of a section to escape to the mould beneath. Each feeding-device is supported by means of flanges 50 adapted to be inserted in grooved guides carried by arms 52 from the frame. After filling the moulds, the cones are depressed and locked, and each set is carried between upper and lower gas burners 63, 64 for cooking. The moulds are subsequently unlocked by the engagement of the roller 46 with a fixed cam 67, and then opened to allow the cones to drop.
