440,658. Packeting-machines. NAYLOR, W. H., 20, The Drive, Adel, and DAY & SONS, Ltd., J., Beeston Royds Works, both in Leeds. July 3, 1934, No. 19597. [Class 94 (i)] Filling-machines, of the kind comprising travelling hoppers arranged to rotate about a vertical axis and to receive vertical movement, co-operating with holders for bags &c. travelling in a concentric path, are arranged with the hoppers closed at the lower ends by swing doors normally closed by counterweights or springs, and opened by cam action at the appropriate times. A number of hoppers 21, 23 are rotated by arms 24, 25 about a spindle 12, and are mounted for vertical displacement by means of slide rods 31 and collars 30. On arrival beneath the funnel 37 of an automatic weighing-machine, the funnel 37 is moved by a cam 45 and the hoppers are maintained in contact therewith by a cam 34, a felt ring 38 affording a tight joint. A predetermined charge is delivered from a funnel 36 and passes into the hopper 21. The funnel 37 is raised and the hopper resumes its rotation and falls to the level indicated at 22 owing to the slope of the cam 34. At this position, the mouth of the hopper enters a bag &c. in a receptacle 16 on a bracket 14 rotated in synchronism with the hoppers about the axis 12. The lower end of the hopper is formed with a tapered lower edge 46, Fig. 3, to fit the top of the bag, and has two flaps 47, 48 adapted to be opened about their hinges 50, 51 by the action of a cam 57 on a roller 56 on an arm 55, to allow the charge to enter the bag. Parts of the cams 34, 57 are serrated to vibrate the hoppers and associated parts, and a semicircular plate 60 is vibrated by cams 64 to shake down the charges in the bags. The containers or holders 16, 19 may be four-sided or may be open-sided to allow the horizontal entry and exit of the bag. In another form, the containers may be curved round an elongated track with circular ends. The apparatus may be used in connection with the machine described in Specification 410,557. Specification 2097/01, [Class 143], also is referred to.
