Abstract
308,091. Hughes, V. A. B., (Cincinnati Grinders, Inc.). March 29, 1928. Centreless grinding; guides and rests.-In a centreless grinding machine the work, in its axial passage through the grinding throat, is ground from end to end to a frusto conical shape but is reduced to a cylinder of the same size as the smaller end of the frustum as it leaves the throat. The machine comprises a cylindrical grinding wheel 10 and a cylindrical regulating wheel 23, the former being mounted in bearings on a bracket 11 angularly adjustable about a vertical axis through a boss 14 on a slide 12 and the latter being mounted in bearings on a slide 24 vertically adjustable on a bracket 27 which is horizontally adjustable on a turntable 29. The table 29 is angularly adjustable about a vertical axis through a boss 30 on the machine frame. Locking screws 15, 31 are provided for the rotary adjustments and the sliding adjustments are made by handoperated screws 17, 25, 28. The work 50 is pushed through the conical throat by a plunger 32, Fig. 3, sliding in a sleeve 33 on the machine frame and actuated against a spring 38 by a beltdriven cam 35 acting on a roller 34 projecting from the plunger through a slot in the sleeve. The work support 21 has two cylindrical surfaces 44, 45, corresponding to the diameters of the rough and finished work respectively, a central surface which may be frusto-conical or of V- shaped section with tapered sides or having a flat upper surface inclined to the horizontal to suit the conicity of the work.
