Abstract
Abstract A round-counter for heavy artillery guns comprises a small block secured ween stationary and recoiling gun parts. A surface of a recoiling part makes frictional surface contact with the stationary block so that erosion of the block through frictional wear is equitable to number of rounds fired. The device can also be used to count revolutions of a journaled shaft or the like.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
112 words
A cycle counter for counting the number of repetitive movements of a first element relative to a second element, comprising: a. a wear member, said wear member adapted to erode at a predetermined rate correlatable with the number of said repetitive movements, b. a first element having means for receiving said wear member and a spring biasing means for urging said wear member towards a second element, c. a second element mounted for repetitive moving relationship to said first element and having a surface in contact with a surface of said wear member, whereby the number of said repetitive movements can be determined by the amount of wear of said wear member.
Claim 2
Dependent Claim
112 words
A cycle counter for counting the number of repetitive movements of a first element relative to a second element, comprising: a. a wear member, said wear member adapted to erode at a predetermined rate correlatable with the number of said repetitive movements, b. a first element having means for receiving said wear member and a spring biasing means for urging said wear member towards a second element, c. a second element mounted for repetitive moving relationship to said first element and having a surface in contact with a surface of said wear member, whereby the number of said repetitive movements can be determined by the amount of wear of said wear member.
Claim 3
Dependent Claim
29 words
The cycle counter of claim 1, wherein; said spring biasing means applies a continuous force to said wear member during the entire period of erosion of said wear member.
Claim 4
Dependent Claim
30 words
The cycle counter of claim 1, further comprising; indicia formed on said wear member for indicating the number of repetitive movements of said first element relative to said second element.
Claim 5
Dependent Claim
20 words
The structure set forth in claim 3, wherein; said indicia comprises striated layers of various colors adapted to erode sequentially.
Claim 6
Dependent Claim
85 words
The cycle counter of claim 1, wherein; said means for receiving said wear member and said spring biasing means is a passage through said first element, the wear member being positioned at a first end of said passage in contact with a surface of said second element, a passage closure means is positioned at the second end of said passage and said spring biasing means is positioned between said passage closure means and said wear member for urging said wear member toward said second element.
Claim 7
Dependent Claim
15 words
The cycle counter of claim 5, wherein; said passage closure means threadedly engages said passage.
Claim 8
Dependent Claim
27 words
The cycle counter of claim 1, further comprising; a sleeve member mounted in said first element, and wherein said cycle counter is mounted in said sleeve member.
