Abstract: 10,646. Baker, G. S. May 5. Depositing - machines; endless - chain machines; shaking - machines. - In machines for filling chocolate moulds &c., means are provided for positively transferring the filled moulds transversely across the table of the filling - machine to t h e tapping-tables. Trays of moulds &c. filled from a depositing-machine 1, pass along a table 2, and are transferred by transverse chains to a single or multiple series of conveyer chains 10, 11 passing over tapping - tables 8, 9 and under rotary stamping- dies 13. The trays are then transferred by hand to conveyers 15, passing through a cooling-chamber 16, after traversing which the moulds are removed and placed upon conveyers 19 and carried to operatives who discharge them. The empty moulds are placed upon an upper return conveyer 20 which delivers them to a conveyer 20<a>, from which they pass to a conveyer 20<b>, traversing a drying- chamber 21 and terminating in a shoot 22 near the depositing-machine. The depositing-machine 2 and tapping-tables 8 are preferably arranged in a room 16<b> isolated from the room 16<a> in which the cooling-chamber 15 is situated. Material contained in the hopper 1<a>, Fig. 3, of the depositing-machine is fed forward by intermittently-operated rollers 23, and is discharged in regulated quantities by a pump 29 operated from the main shaft 24 by means of an eccentric 30 and connecting-rods 31, 32 coupled by an adjusting-link 33. Trays of moulds are fed forward by a chain 3 operated intermittently by ratchets 42, 47 arranged about a shaft 53 and adapted to impart to the chain an intermittent forward, and a periodic skip movement. The table 2 over which the chain 3 passes is rocked by means of a rod operated by a cranked lever actuated by a cam 36<a>. The filled trays pass along the table 2 to the chains 4 which pass round chain wheels 54 mounted upon a shaft 50, Fig. 6, driven intermittently through bevel-gearing 52, Fig. 8. One gear 52 is mounted loosely upon the shaft 53 and is provided with a chain wheel 92, connected by a chain 91 to a chain-wheel 90 mounted loosely upon the main shaft 24 and intermittently coupled thereto through the medium of a disk 92<a> and clutch bolt 88 carried by a disk 87, operated by a forked member 86, 85 carried by a abaft 84 which is rocked by a cam 70 engaging an arm 83. A cam 93 on the disk 92<a> acts upon the arm 86 to disengage the clutch. As the trays pass along the table 2, the end one is engaged by a roller 57, Fig. 6 driven by bevel-gearing from the shaft 50, and is fed rapidly forward. In a modification the shaft 50 is driven intermittently through Geneva-stop gearing. The trays pass from the table 2 directly to the tapping-tables or on to an intermediate table 5, Fig. 10. An auxiliary chain 4<a> is provided in case the trays are not properly engaged by the chains 4, and an inclined abutment 7 positions the trays correctly on the table 5. Chains 6 feed the trays across the table 5, and a transverse chain. 12 arranged above the trays feeds them alternately to the second series of tapping-tables 9. The chains 6, and chains 10, 11 passing over the tapping-tables 8, 9, are driven continuously from a shaft 103 through bevel and other gearing, and the chain 12 is driven intermittently from a secondary shaft 109 through intermittent gearing 111, 112.
