Abstract

432,285. Trueing rotating tools. HEARD, F. G., 4, Oakington Avenue, Harrow Garden Village, Middlesex. Jan. 26, 1934, No. 2782. [Class 60] The operative surfaces of the grinding and control wheels of a centreless grinding-machine are trued in succession by a single cutter under the control of a single cam or former. The former A is of circular cross-section and is supported by the rest E, and adjusted and secured by screws A<1>, A<2> and distance-pieces A<3> passing through the heads of bolts A<4>, the screws being mounted in arms D<2> secured to the rest, and carrying a bar D<3>. On this bar is slidable, by means of a screw H, a housing D, in which is slidable transversely a carrier C having downwardly projecting parts C<3>, C<4> provided with coaxial rectangular openings to receive a block B<2>, held in position by a screw B<4>. The block receives a tapered holder B carrying a diamond or other cutting-point B and on the rear end of the block is a steel rod or wire tracer B<3>, which engages with the former A, being held there against by a spring plate F secured to the housing D by a screw F<1> ; cooling liquid is supplied by a nozzle G projecting through the plate F, and a similar plate F is provided on the opposite face of the housing. In operation, the housing is moved parallel to the axis of the grinding-wheel X, by the screw H, the block B<2> lying in the opening C<5> and being moved in the housing towards and from the axis of the wheel by the cam. The block is then moved to the opening C<6>, and the control wheel Y is similarly shaped. In a modification, the housing D is carried by a slide located above the wheels X, Y.
