Abstract

A quality-control device comprises a housing, a biasing member disposed within the housing, and a reciprocating puncturing member that is configured and oriented to selectively move inwardly of the housing in opposition to the biasing member. A maximum-compression indicator is configured to move inwardly of the housing in tandem with the puncturing member and a gauge serves to correlate a particular location of the maximum-compression indicator to a corresponding measure of compression as corresponds to a material being tested for quality. By one approach the indicator moves in response to inward movement of the puncturing member but is also configured to not move when the puncturing member moves outwardly of the housing. So configured the maximum-compression indicator will remain located at a point that corresponds to the furthest inward incursion of the puncturing member in opposition to the biasing member when the user presses the puncturing member against the material.

First claim

What is claimed is:

1. A quality-control device to test material quality of corrugated board, the quality-control device comprising:
a housing;
a reciprocating puncturing member;
a biasing member configured to oppose inward movement of the reciprocating puncturing member with respect to the housing;
a maximum-compression indicator configured to move inwardly of the housing with the reciprocating puncturing member;
a gauge configured to correlate a particular location of the maximum-compression indicator to a corresponding measure of compression as corresponds to the corrugated board.

2. The quality-control device of claim 1 wherein the biasing member is co-axially aligned with the reciprocating puncturing member.

3. The quality-control device of claim 1 wherein the maximum-compression indicator comprises a hand-resettable maximum-compression indicator.

4. The quality-control device of claim 3 wherein the maximum-compression indicator is further configured to not move when the reciprocating puncturing member moves outwardly of the housing.

5. The quality-control device of claim 1 wherein the biasing member comprises a spring.

6. The quality-control device of claim 5 wherein the spring comprises a calibrated compression spring having a rated tolerance of no more than plus/minus ten percent.

7. The quality-control device of claim 1 and further comprising:
a hand-graspable handle operably coupled to the housing to permit a user to apply the reciprocating puncturing member to the corrugated board to test the material quality of the corrugated board.

8. A method comprising:
providing a housing;
providing a reciprocating puncturing member;
disposing a biasing member to oppose inward movement of the reciprocating puncturing member with respect to the housing;
disposing a maximum-compression indicator to move inwardly of the housing with the reciprocating puncturing member;
disposing a gauge to correlate a particular location of the maximum-compression indicator to a corresponding measure of compression as corresponds to a sample of corrugated board.

9. The method of claim 8 wherein the biasing member is co-axially aligned with the reciprocating puncturing member.

10. The method of claim 8 wherein the maximum-compression indicator comprises a hand-resettable maximum-compression indicator.

11. The method of claim 8 wherein the maximum-compression indicator is further configured to not move when the reciprocating puncturing member moves outwardly of the housing.

12. The method of claim 8 wherein the biasing member comprises a spring.

13. The method of claim 12 wherein the spring comprises a calibrated compression spring having a rated tolerance of no more than ten percent.

14. The method of claim 8 and further comprising:
operably coupling a hand-graspable handle to the housing.
