Abstract

792,869. Squares. BLAKEMORE, W. March 16, 1956 [March 14, 1955], No. 7322/55. Class 97(3) A right angle is defined between a cylindrical or partcylindrical surface and the base of the cylinder which is, or incorporates, a magnet for securing to a workpiece. As shown, a hollow cylinder 11 is closed at the ends by a plate 11 and a magnet 12 with pole pieces 13, 14 and a central brass plug 15. The plug 15 and the plate 11 are drilled to provide centres from which the cylindrical surface and the magnet face are ground. The body of the device may be part cylindrical e.g. square with cylindrically ground corners or cruciform. A keeper 22 is supplied for the magnet.
