Abstract
567,149. Clamping flasks and moulds. DARWINS, Ltd., and LINLEY, A. Nov. 23, 1943, No. 19555. [Class 83 (i)] A foundry core- or mould-box 6 has a ferromagnetic core-plate 5 covering one end thereof, to receive the core &c. when detached from the box, and the box has magnetic devices to hold the plate detachably. The magnetic devices are preferably embedded in two sides of the box 6 and may consist of a double electromagnet 23, Fig. 3, controlled by a switch which may pass a momentary current in the reverse direction when being switched off. In a modification, each device consists of three permanent magnets 8, 9, 10, Fig. 2, are arranged between polepieces 12, 13 which extend to the end of the box 6. The magnet 9 is mounted on a spindle 15 so that it can be turned through 180 degrees and thus neutralize the magneism of the magnets 8, 10 and release the plate 5.
