Abstract

946,332. Depth gauges. S. NAKATA. April 28, 1961, No. 15527/61. Heading G1M. A depth gauge comprises a body 1, having an aperture 2, for a measuring rod 3, and a threaded spindle 4 for rotation within the body. The spindle 4 has ball means 7 serving as an abutment for rod 3 and spring means comprising a split ring 9 in a spring bushing, to grip rod 3. Spindle 4 is rotated by a micrometer thimble 16 and rod 3 is rotated with the spindle by means of split ring 9 until the rod 3 engages the measuring surface. When the friction between the measuring surface and end 13 of rod 3, due to pressure of ball 7 on end 14 of rod 3, is greater than that between the ring 9 and rod 3 the rod stops rotating with thimble 16. At this point the reading is taken.
