Abstract

422,092. Making keys for locks. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Automatic Musical Instrument Co. ; 1500, Union Avenue, Grand Rapids, Michigan, U.S.A.) March 22, 1934, No. 8975. [Class 83 (ii)] [See also Group XXV] In making a key, for the lock described in Specification 422,093, [Group XXV], in which the sides of the grooves 20 have neither a fixed relation to one another, nor to the centre line of the groove, surfaces are located instead of centre lines. The surfaces in one side are determined and a cut is milled to include these surfaces. Then the opposing surfaces for example 23 are found and a second cut is made to provide them.
