ABSTRACT:
A recorder-indicator which mechanically magnifies strain or movement using special flex pivots. The lever system is activated by the motions being recorded or observed. A pointer indicates the strain or movement. It also marks or scribes a record of maximum movement on a recording medium having a scale. The recording media may be placed in a slide for projecting the recorded data and scale on a screen for enlargement.
The recording media may be moved in the "Y" direction by one of several means to separate events recorded in the "X" direction.
One of the features of the invention is the type of flex pivots that are suitable for small angular motion with minimum distorsion under high load. These pivots may be placed close to each other without interference. Other species of flex pivots are inexpensive to manufacture and still other flex pivots are suitable for relatively large loads and angular movements.
The amplified motion is also used to activate limit switches.
