Abstract: 24,228. Averay-Jones, H. T. Nov. 5. Moulding confectionery.-Fig. 1 shows a side elevation, Fig. 2 an end elevation, and Fig. 3 a partly - sectional elevation on a larger scale, of a machine for making confectionery, such as chocolate creams and the like, in which one plastic material is enveloped by another. The filling and enveloping materials are contained in receptacles b, c arranged one within the other and mounted over one end of a long table a. The receptacles are jacketed so that the materials may be heated or cooled, and outlet apertures are made in the bottom of each receptacle. Each outlet b<3> of the inner receptacle is fitted with a cylindrical valve d having a conical nozzle d' adapted to close the outlet c<5> in a valve seating c' fitted in the corresponding outlet c<3> of the outer receptacle. A valve rod e, arranged within the valve d, has a conical end adapted to close the valve outlet d<2>, through which the filling-material contained in the inner receptacle b passes. The valves d are carried by vertical members d' attached to a crosshead d<4>, and the rods e by a crosshead e<2>. The crossheads are connected at their ends to rods d', e<3> reciprocated in vertical guides f, the lower ends of each pair of rods being connected by links g to arms g<1> on a transverse shaft g', a crank-arm g<3> on which carries an adjustable roller g<4> bearing against a cam g<5>. The cam g<5> is carried by a rod h<2> adjustably connected to a rocking-arm h<1> actuate d by the main shaft h. Or the valves d may be stationary, and the valve seatings c<4> and valve-rods e reciprocated. The materials fall from the receptacles into moulds i, Fig. 12, which are formed with a spirally-arranged fold i<1>, at which the mould is severed. The moulds are formed with two flanges i<3>, i<4> and an intervening tapering part by which they are held in openings in mould plates j, which are traversed along the table by chains k provided with projections. The chains pass over wheels k', and are driven by a shaft receiving motion through ratchet gearing from the main shaft. The table a is vibrated on a hinge a', or it may be raised and lowered ; and, in order to keep the chain k taut, one of the wheels k<2> is mounted on a knee-joint m, the arms of which are pivoted to the table and machine frame. The plates and moulds, on reaching the end of the table, are guided by chains n into a setting or cooling chamber o, down which they are gradually lowered and subjected to an ascending current of cold air. The chains n are mounted on wheels n' carried by shafts n<2>, n<3>, the shaft n<2> being driven through bevel gearing from a shaft n<5> provided with a ratchet-wheel n<6> actuated by a pawl n<7> and rod n<8> from a cam h<5> on the main shatt. The lever n<8> is connected by a link n<9> to a pivoted lever n<10>. When a mould reaches the end of the table, the upper arm of the lever n<10> is forced outwards, and the lever n<8> is forced against the cam h<5> which then actuates the wheel n<6>, a spring n<12> returning the lever n<8> to its original position. The plates are guided out from the bottom of the chamber o by a chain p, and may then ascend another similar chamber o', after which they are conveye i by the chain k to the table a. The plates, before reaching the table, are inverted by guides q rotated by a pulley q<1>, a guard q<3> preventing the plates from falling out of the guides while being inverted. The moulds are tapped on their bases by an ejector a' attached to the underside of the table, so as to be loosened in their plates and to expand, owing to their folded severed formation, and so allow the moulded and set confection to fall out into any suitable receptacle, the moulds being retained in place by their flanges i<4> . The moulds and plates are then carried forwards by the chains and delivered into any suitable receptacle, from which they are re delivered on to the chain at the charging end of the machine. In another arrangement, the materials from the receptacles drop on to flat plates or boards which are traversed along the table by chains until they arrive at the point where the table is hinged, when they are inverted by means of guides. To prevent the confections from adhering to the plates and not falling off, the plates may be turned over on to a wire grid, which also serves to ornament the article. The plates with the confections on their undersides are then passed through the cooling chambers and delivered in their inverted position.
