Abstract

666,058. Testing physical qualities of moulding sand. FIFE, J. G. (Meehanite Metal Corporation). Sept. 21, 1949, No. 24312/49. Class 106 (ii). Apparatus for determining the toughness of moulding sand comprises a holder 23 for the test specimen 13 and a pendulum 26 provided with a striker 21 shaped and adjusted in height as shown in Fig. 3 to break the specimen in shear. The residual energy of the pendulum after breaking the test specimen causes it to contact the striker 31 of a non-return pointer 25 moving it over a scale 24 which may be calibrated in arbitrary toughness units. For example, units comparable with those normally obtained by multiplying the compression strength of the sand by the deformation of the sand under a compression load. In order to preheat the test specimen a portable furnace may be placed over the holder 23 and removed immediately prior to the test. In a modified form of apparatus shown in Fig. 4 a furnace 30 provided with heating elements 15 and insulating material 19 is positioned beneath the base 10. A movable member 33 raises the holder 23 and specimen 13, from the interior of the furnace, as shown in Fig. 5, to the testing position shown in Fig. 4, when the test may be made as before, without cooling the test specimen appreciably. Tests may be made at various temperatures and the curves shown in Fig. 10 obtained in order to determine the characteristics of the moulding sand at various distances from the surface of the mould or core.
