Abstract
Abstract Apparatus and method for monitoring a condition of a textile machine including switch means mounted adjacent the machine having an open and closed position and means mounted on the textile machine for causing the switch means to alternately change status while the machine is in operation, the frequency of the status changes being a function of the condition being monitored. In the specific embodiment disclosed, a reed switch is mounted adjacent one of the dials on a hank counter which carries a portion of magnetic material within it so that the reed switch is periodically closed as the hank counter dial rotates to indicate the production of a given amount of material. The reed switch is attached to appropriate electrical circuitry so that a first electrical condition results when the switch is closed, and a second condition when the switch is open and the electrical conditions are periodically polled at a frequency greater than the frequency at which the switch condition changes so that all changes of status are detected and so that each change represents a specific quantity of output material produced.

Total Claims: 18
Claim 1
Independent Claim
189 words
Apparatus for sensing a condition of a textile machine comprising: a hank counter, switch means mounted in association with said textile machine including a switch having two contacts which contact when magnetic material is placed within a given distance of said contacts and separate after said material is removed from within said given distance, means mounted on said textile machine for causing said switch means to alternately change from said first to second position and from said second to said first position while said machine is in operation so that the frequency of said changing varies with said condition including a dial of said hank counter which rotates at a speed which is a function of a given machine condition and at least a single piece of magnetic material mounted on said dial so that said piece approaches within said given distance and is subsequently removed from said given distance at separated intervals of time, and means for checking the position of said switch means at a frequency greater than said frequency of said changing and for using the number of changes of said position to determine said condition.
