277,271. Sadler, E. June 21, 1927. Pottery, throwing and turning.-A horizontallydivided two-part plaster mould 7, 9 is encased in a vertically-divided metal container 4 which is shaped externally to fit the jigger head 3 and internally to fit the outer surface of the mould. A shoulder 4 limits the downward movement of the container. When the container and mould are lifted bodily from the jigger head after the jolleying operation is completed the container is at once removed to be used again.
