Abstract
An improved indicating thread gage for gaging the functional fit and individual thread parameters of threaded products, especially taper threaded products. Thread form elements engage the threaded product and are capable of longitudinally traversing the threaded product while an indicator transduces radial displacement of the thread form element.
Claims18
An indicating thread gage for tapered threads comprising:
- an active block slidably engaged to a guide rail passing therethrough;
- a biasing means for biasing the active block to a neutral position;
- a fixed block engaged to the guide rail passing therethrough;
- an indicator for transducing movement of the active block along the guide rail;
- an active arm with one end secured to the active block;
- a fixed arm with one end secured to the fixed block;
- and
- a thread form element engaged with a section of the active arm not fixed in the active block;
- a second thread form element engaged with a section of the fixed arm not fixed in the fixed block;
- each thread form element biased to a neutral position, but capable of sliding movement along the active arm and fixed arm, respectively.

An indicating thread gage for gaging tapered threads comprising:
- an active block slidably engaged with a guide rail passing through the active block, said active block biased to a neutral position along the guide rail, said active block having a wear pad for contacting with a threaded product;
- a fixed block engaged to the guide rail passing through the fixed block, said fixed block also having a wear pad for contacting with the threaded product;
- an active arm with one end secured to the active block;
- an indicator for transducing movement of the active block and active arm in response to variations in the tapered thread;
- a fixed arm with one end secured to the fixed block;
- a thread form element capable of mating with the tapered thread and engaged with a section of the active arm not fixed in the active block;
- a second thread form element capable of mating with the tapered thread and engaged with a section of the fixed arm not fixed in the fixed block;
- each thread form element biased to a neutral position, but capable of movement along the active arm and fixed arm, respectively.
