746,533. Linear-dimension gauges. MICROMATIC HONE CORPORATION. Jan. 27, 1954 [Feb. 6, 1953], No. 2494/54. Class 106 (2). [Also in Groups XXIII and XXX] A machine for honing the bore of cylindrical workpieces, utilizing an expanding honing tool 14, has a gauging device comprising a ring 51 of hard material which is engaged by the stones when they have been expanded to a predetermined diameter. The ring is secured to a flanged ring 52 mounted in an aperture 53 by a clamping plate 45 which is secured by screws 55 to the projecting plate 54 of a bracket 46 secured to the honing head about the honing tool 14. Flanged ring 52 is free to rotate within aperture 53 and has a slot 56 into which projects the downwardly turned end 57 of a spring wire 58. The opposite end of the wire extends into a block 59 mounted in the enlarged end of an aperture 61, the block and wire being secured by a screw 62. The degree of deflection of the wire is controlled by an adjustable block 63. An insulated wire 67 extends through a sleeve 68 mounted on arm 69 carried between flanges 71 of a screw 72; the sleeve 68 extends within an aperture 73 in plate 54 and the wire 67 has a conducting tip 74 extending forwardly from the end of the sleeve 68; the tip 74 is aligned with the deflectable wire 58, and when the wire and tip make contact, a circuit is completed which actuates mechanism in the honing head to collapse the honing tool and thus stop honing.
