Abstract
606,459. Angle gauges. ZIMMERMANN, E. Jan. 15, 1946, No. 1327. Convention date, Jan. 15, 1945. [Class 97 (iii)] An instrument for testing the angles of a twist drill comprises a channel member of V- section 10 adapted to receive the drill 26, a graduated quadrant 13 upstanding from the ridge of the channel member 10, an arm 15 pivoted at the centre of the quadrant and provided with an extension 18 moving over the scale and with means for locking, and a second arm pivoted at one end in a slot in the arm 15. 23 is a lock-nut for fixing the second arm 22. The ends 12 of the channel member 10 and 25 of the arm 22 are formed at suitable angles for testing the shape of the drill.
