Abstract
Abstract A gauge which is constructed to measure a thread of varying pitch, and which includes a threaded gauge element adapted to be screwed into engagement with the thread of varying pitch and to a point at which the threads have a light binding relationship resisting further advancement of the threads together, in combination with a dial indicator adapted to indicate the position at which the binding of the threads occurs as a measurement of the thread of varying pitch. The device may include a second element which is shiftable axially relative to the threaded gauge element to a position limited by engagement with the part containing the thread of varying pitch, with the dial indicator being responsive to and adapted to indicate the relative positioning of the two elements.

Claim 1
Independent Claim
82 words
A gauge for measuring a thread of varying pitch formed on a work part, said gauge comprising: an element having a thread adapted to be screwed along an axis into engagement with said thread of varying pitch and to a position at which binding of the threads offers resistance to further advancement of the threads together; and a dial indicator operable to indicate the position at which said binding of the threads occurs as a measurement of said thread of varying pitch.
Claim 2

Claim 4
Dependent Claim
24 words
A gauge as recited in claim 2, including means yieldingly urging said second element in a predetermined axial direction relative to said first element.
Claim 5
Dependent Claim
19 words
A gauge as recited in claim 2, including means for manually actuating said elements axially relative to one another.
Claim 6
Dependent Claim
25 words
A gauge as recited in claim 3, including means for manually actuating said second element in an opposite axial direction relative to said first element.
Claim 7
Dependent Claim
42 words
A gauge as recited in claim 3, including a flange on one of said elements and a projection on the other element adapted to be manually pressed together to manually actuate said elements in an opposite axial direction relative to one another.
Claim 8
Dependent Claim
53 words
A gauge as recited in claim 2, in which said dial indicator includes a body connected to one of said elements and a sensing member actuable by the other element to produce a display indicating the position at which binding of the threads occurs as a measurement of said thread of varying pitch.
Claim 9
Dependent Claim
115 words
A gauge for measuring a thread of varying pitch formed on a work part, said gauge comprising: an element having a thread adapted to be screwed along an axis into engagement with said thread of varying pitch and to a position at which binding of the threads offers resistance to further advancement of the threads together; a second element which is movable slidably relative to said first mentioned element and said thread thereof to a position limited by said work part when said threads are in binding engagement, and means for then indicating the position of said second element relative to said first mentioned element as a measurement of said thread of the work part.
Claim 10
Dependent Claim
115 words
A gauge for measuring a thread of varying pitch formed on a work part, said gauge comprising: an element having a thread adapted to be screwed along an axis into engagement with said thread of varying pitch and to a position at which binding of the threads offers resistance to further advancement of the threads together; a second element which is movable slidably relative to said first mentioned element and said thread thereof to a position limited by said work part when said threads are in binding engagement, and means for then indicating the position of said second element relative to said first mentioned element as a measurement of said thread of the work part.
Claim 11
Dependent Claim
23 words
A gauge as recited in claim 8, including means yieldingly urging said second element in one axial direction relative to the first element.
Claim 12
Dependent Claim
23 words
A gauge as recited in claim 8, including a spring yieldingly urging said second element in an axial direction toward said work part.
Claim 13
Dependent Claim
25 words
A gauge as recited in claim 8, including means for manually actuating said second element in a predetermined axial direction relative to said first element.
Claim 14
Dependent Claim
50 words
A gauge as recited in claim 8, including a spring yieldingly urging said second element in a first direction relative to said first element axially toward said work part, and means for manually actuating said second element in an opposite direction relative to said first element to a retracted position.
Claim 15
Dependent Claim
46 words
A gauge as recited in claim 8, including a coil spring contained within an internal recess in said second element and about said first element and yieldingly urging said second element in a predetermined axial direction relative to said first element and toward said work part.
