Title: Improvements relating to the manufacture of pottery
IPC: B28B1/02
Filed: 1928-01-23
Abstract: 285,871. Miller, W. J. Feb. 24, 1927, [Convention date]. Pottery, throwing and turning.-In the manufacture of pottery ware positive association between the chuck C and the mould A is produced intermittently by such means as magnetic attraction or fluid pressure. The chuck C which is surrounded by an electromagnetic ring 6, provided with a magnetizing coil 9 adapted to be energized 'through which is commutator rings 10, 10a and brushes 11, 11<a>. The metal base A of the mould, which may be of the kind described in Specification 283,894, is thus caused to adhere to, and rotate with, the chuck. When the chuck is rotated, resiliently mounted pins 26 on a resiliently but non-rotatably mounted stud 19 on the chuck engage helical grooves in the underneath of the base A of the mould. To disengage the mould from the chuck the latter may be stopped by a brake-band round the lower edge thereof, a lug near 10<a> on the band engaging a fixed stop near 6. Fluid-pressure is applied to the mould through a passage 39 passing through the spindle, chuck, stud 19, and base A and communicating with recesses 17 and 32 of the chuck. A rubber sealing-ring 40 engages the base A when the chuck is raised. Suction can thus be applied through holes 70 in the base A to holes 70a, 70b in the porous plasterbody B, thereby extracting air from between the clay charge and the mould, drying the charge, and causing the body B to adhere to the base A. Air under pressure may also be applied to eject the shaped article. The outer surface of the mould body B may be coated to increase the fluid-pressure effect. During the application of fluid-pressure the base A is firmly held to the chuck by the stud 19 and electromagnet 6. The fluid pressure and energizing electric current are controlled by a plunger 44 operated in synchronization with the movements of the chuck by a cam 62. Ports 42, 43 in the plunger register alternately with the passage 39, the port 42 registering simultaneously with a pipe 47 to which suction is applied, and the port 43 opening into a tube 46 open to atmosphere or subject to pressure. To prevent drag of the electromagnet the current is reversed while the brushes 11, 11<a> are in contact with the rings 10, 10<a> by a switch Fig. 6 carried by the plunger 44. The mechanism for reciprocating and rotating the moulds comprises a fork 54. rod 55, lever 59, cam 62, and friction gears 63, 64 as described for example in Specification 284,692. When suction alone is employed the mould may be entirely of plaster. Specifications 283,151 and 308,836 also are referred to.
