Abstract
Abstract A dimensional measuring machine is provided and has a pair of parallel ways arranged on opposite sides of the machine and a pair of supports supported for reciprocating movements on the ways, with an elongated bridge construction extending substantially perpendicular and being carried by the supports. A gage head is provided and carried on a carrier which is supported for reciprocating movements along the bridge construction. The machine has means measuring the positions of the supports along the ways and providing electrical output signals and means measuring the position of the carrier along the bridge construction and providing another electrical output signal. The machine also has an electrical system for receiving and comparing the electrical signals and providing a signal representing the actual position of the carrier and gage head from a reference location.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
178 words
A machine comprising, a first way arranged on one side thereof, a second way arranged on the opposite side thereof parallel to said first way, a first support supported for reciprocating movements along said first way, a second support supported for reciprocating movements along said second way, a bridge construction extending perpendicular to said ways and being supported by said supports, a carrier supported for rectilinear reciprocating movement along said bridge construction, first means measuring the position of said first support from a reference location and along said first way and generating corresponding electrical signals, second means measuring the position of said second support from said reference location and along said second way and generating corresponding electrical signals, third means measuring the position of said carrier along said bridge construction and generating corresponding electrical signals, and an electrical computation system receiving said electrical signals corresponding to the position of said first and second supports and said carrier and generating from said corresponding electrical signals a signal which represents the actual position of said carrier from said reference location.
Claim 2
Dependent Claim
178 words
A machine comprising, a first way arranged on one side thereof, a second way arranged on the opposite side thereof parallel to said first way, a first support supported for reciprocating movements along said first way, a second support supported for reciprocating movements along said second way, a bridge construction extending perpendicular to said ways and being supported by said supports, a carrier supported for rectilinear reciprocating movement along said bridge construction, first means measuring the position of said first support from a reference location and along said first way and generating corresponding electrical signals, second means measuring the position of said second support from said reference location and along said second way and generating corresponding electrical signals, third means measuring the position of said carrier along said bridge construction and generating corresponding electrical signals, and an electrical computation system receiving said electrical signals corresponding to the position of said first and second supports and said carrier and generating from said corresponding electrical signals a signal which represents the actual position of said carrier from said reference location.
