Abstract

632,933. Magnetic work-holders. CARSON, G. J. Aug. 23, 1946, No. 25247. [Class 60] A swivelled magnetic work-holder of the type which can be positioned angularly with respect to a base or tool comprises a support, aligned journals therein, a permanent magnet holding device having a boss at each end mounted in the journals for rotation. about an axis on the support, means for rendering the holding device operative and inoperative, said means being rotatable bodily as the holding device is rotated, and a handle to operate said means for its intended purpose independently of the rotative position of the holding device. The work-holder comprises bottom and top plates 10, 12, within which is mounted a permanent magnet assembly 16 rotatable within the plates 10, 12, so that the effective flux of the magnet may be turned on or off. The plates 10, 12, which are held together by screws, are secured to bosses 30, 34 which are journalled in supports 28, 32. Independent rotation of the magnet 16 with respect to the plates 10, 12, and of the work-holder with respect to the supports is thus possible.
