Abstract
305,839. Hughes, V. A. B., (Cincinnati Grinders, Inc.). Feb. 25, 1928. Centreless grinding; guides and rests. - In a machine for cleaning up or finishing thin hollow or solid bodies of substantially cylindrical shape but which are slightly conical or non-circular, the work is freely supported in contact with a grinding wheel so as to be capable of angular and lateral movement. The machine comprises a grinding wheel 12 rotated at high speed by a belt 13 and a regulating wheel 15 rotated at a low speed by a belt 74, gearing 80, 81, and a flexible shaft 72, 16. The bearings for the regulating wheel are carried on a frame 18 pivotally supported by a shaft 19 on a base 21 which may oscillate freely about a trunnion 31 on a slide 30 movable to and from the grinding wheel by a hand wheel 37. The base 21 is provided with rollers 32 to assist the freedom of oscillation about the trunnion 31 and the frame is supported at the rear by plungers 45 urged by springs 51 against studs 47 on the base, the pressure of the springs being adjustable by nuts 49, 50. The regulating wheel 15 is moved to and from its operative position by a pedal 60 and a link 25 attached to the frame 18. In operation, when the regulating wheel has been withdrawn by the pedal, the work W is placed upon a roller 40 rotatable on a bracket 43 attached to the slide 30 and is kept in position by a fixed blade 65 on the base. The regulating wheel is then allowed to come in contact with the work and pressed it, by means oE the springs 51 and a weight 22, against the grinding wheel in such a manner that the latter is able to grind it uniformly all over without removing an undue amount of material at any point. The work may subsequently be preserved by lacquering &c. Grinding fluid is supplied to the work by a pump 78.
