Abstract
282,072. Miller, W. J. Dec. 7, 1926. [Convention date]. Feeding; cutting-machines. - Moulds for the manufacture of pottery are charged with plastic material by feeding the material intermittingly from a container on to a former, severing the charge on the former, performing the charge on the former and lifting the charge therefrom and depositing it in a mould. As shown, a container 6, supplied with plastic material through a shoot 13, is fitted with a feed screw 12 co-operating with reversely-inclined ribs 14 to feed material through an interchangeable die 9<a> on to a former 28, the charge being severed by a reciprocating cutter 34. After charging, the former 28 moves into alignment with a member 41 which first descends to preform the charge, then rises with the charge and finally, after the return of the former 28, again descends and by impact with a stop 51 forcibly deposits the charge in a mould 52. A main shaft 27 operates the screw 12 through a cam groove 25<a>, roller 25, lever 23, rack bar 22, ratchet 21 and bevel gear 78, 17 ; the former 28 through a cam 33, lever 30 and rod 29; the cutter 34 through a cam 39, lever 37 and rod 36; and the member 41, which is carried by a. lever 43 pivoted at 43a, through a cam 50, lever 46 and link 45. Springs 30<b>, 40 and 49 co-operate with the cams 33, 39 and 50 respectively. To clear the cutter 34 on its return movement, a slight reverse movement is imparted to the screw 12 by a block 57 secured to the bar 22 and engaging a screw 56. The member 41 carries a plate 42 furnished with tapered openings 42<b> to engage the charge on the former 28 and ensure its removal therefrom. Adjustable shims 28<b>, 35<a> support the member 28 and cutter at the required heights. The moulds 52 are cleared by an air jet 53. A modified form of machine and cutter are illustrated but not described. Specifications 279,503 and 280,882, [both in Class 87 (i), Bricks &c.], are referred to.
