Abstract

678,227. Reciprocating machines. TRAININ, F. B. Nov. 28, 1950 [Nov. 28, 1949], No. 30473/49. Class 35. A vibrator for dental moulds comprises a portable casing adapted to stand on a table &c. and to enclose an electromagnet comprising a fixed part and a vibratory armature resiliently mounted relatively to the casing and a transmission rod connected to the armature and freely passing through a hole in the casing, the said rod carrying a tray or plate, as shown, the casing 18 encloses a core 5 and an armature 3 resiliently supported by a spring 4 fixed to a base-plate 7. The armature 3 carries a rod 2 which projects upwardly through a hole 21 in the casing. A tray 1 is carried by the rod 2. The armature vibrations can be relatively weak or strong according to whether the whole or half of electromagnet coil is energized.
