Abstract
Extension standards are provided for outside micrometers and calipers. Sleeves engage the extension standards and the micrometer anvil and/or spindle, or the measuring surfaces of calipers, to selectably position the measuring gap and also to provide different sizes of such measuring gaps at those positions.
Claims28
An accessory for outside micrometer calipers, comprising:
- a measuring standard having first and second spaced faces, said first and second spaced faces being spaced from each other a known distance, said measuring standard having a uniform external surface in a direction at right angles to said spaced faces;
- and
- a sleeve, said sleeve having a surface sized to engage upon said external surface of said measuring standard so that said measuring standard is slidable with respect to said sleeve in a direction at a right angle to said faces so that said measuring standard can engage against a measuring surface of a micrometer or caliper by sliding of said measuring standard in said sleeve to reduce the measuring gap by a distance equal to the length of the measuring standard and position the measuring gap that distance away from the measuring surface whereby said measuring standard can be inserted in said sleeve at the location where the measurement is to be made without adjustment so that accurate adjustments can be made at remote locations away from measuring references.
An outside micrometer caliper with accessories, comprising:
- a micrometer having a C-shaped frame, an anvil fixedly mounted on said frame and a spindle movably mounted on said frame, said anvil and said spindle being cylindrical and lying on the same axis, said anvil and said spindle each having a measuring face facing each other so that measurement may be made therebetween by movement of said spindle;
- a sleeve sized to engage upon said anvil;
- a measuring standard of known length slidably held by said sleeve in face-to-face contact with said anvil measuring surface so that said measuring standard can slide in said sleeve to firmly engage said measuring face on said anvil so as to reduce the measuring gap and position the measuring gap away from said anvil by said known length of said measuring standard that said measuring standard can be inserted in said sleeve so against said measuring face of said anvil at a measuring location without need for adjustment and provide accurate measurement.
An outside caliper with accessories, comprising:
- a caliper having a first measuring surface in a fixed position and a second measuring surface which is movable with respect to said first measuring surface and means connected thereto for indicating the distance between said first and second measuring surfaces;
- a first measuring standard having opposite faces thereon of known distance therebetween;
- and
- mounting means for slidably retaining one surface of said measuring standard so that said measuring standard can slide inside said mounting means so that it can be placed in said mounting means at the measuring location and lie against one of said measuring surfaces so as to create a measuring gap between said measuring standard and the other measuring surface so that the measuring gap can be selected in both size and position at the measuring location without further adjustment.

An accessory for outside micrometers and calipers, comprising:
- first and second measuring standards, each of a length selected from a group of measuring standards having a plurality of lengths;
- and
- first and second sleeves, said sleeves each having a surface sized to engage upon and retain said measuring standard so that each said measuring standard can engage against a measuring surface of a bow micrometer or caliper to reduce the measuring gap between said measuring surfaces by a distance equal to the total length of the measuring standards and position the measuring gap a distance away from both the measuring surfaces.
An accessory for outside micrometers and calipers, comprising:
- a measuring standard in the form of a right circular cylinder;
- and
- a sleeve having a concave surface sized to engage on the outside of said measuring standard, said sleeve being a half cylindrical tube made of magnetic material, so that said measuring standard can engage against a measuring surface of a bow micrometer or caliper to reduce the measuring gap by a distance equal to the length of the measuring standard and position the measuring gap that distance away from the measuring surface.
An outside micrometer caliper with accessories, comprising:
- a micrometer having a C-shaped frame, an anvil fixedly mounted on said frame and a spindle movably mounted on said frame, said anvil and said spindle being cylindrical and lying on the same axis, said anvil and said spindle each having a measuring face facing each other so that measurement may be made therebetween by movement of said spindle;
- a first sleeve sized to engage upon said anvil;
- a second sleeve sized to fit on said spindle;
- a first measuring standard of known length held by said first sleeve in face-to-face contact with said anvil measuring surface so as to reduce the measuring gap and position the measuring gap away from said anvil by said known length of said first measuring standard;
- and
- a second measuring standard of known length held by said second sleeve in face-to-face contact with said spindle measuring surface so as to reduce the measuring gap and position the measuring gap away from said spindle by said known length of said second measuring standard.

An outside caliper with accessories, comprising:
- a caliper having a first measuring surface in a fixed position and a second measuring surface which is movable with respect to said first measuring surface and means connected thereto for indicating the distance between said first and second measuring surfaces;
- a first cylindrical measuring standard having opposite faces thereon of known distance therebetween;
- a first clamp for mountably retaining one face of said first cylindrical measuring standard against said first measuring surface;
- a second cylindrical measuring standard having opposite faces thereon of known distance therebetween;
- a second clamp for mountably retaining one face of said second cylindrical measuring standard against said second measuring surface so as to create a measuring gap between said measuring standard and the other measuring surface so that the measuring gap can be selected in both size and position, said first and second cylindrical measuring standards being selected from a group of cylindrical measuring standards having different lengths between their faces.
