Abstract A linear displacement amplification device having fulcrum means rockably engaging opposite sides of a lever in a common plane normal to the longitudinal axis of the lever and restrained against sliding movement along the lever, and means supporting one fulcrum, means for movement lengthwise of the lever relative to the other fulcrum means in response to a linear input displacement. This relative movement of the fulcrum means causes lateral displacement of one end of the lever proportional to but substantially greater than the input displacement. A deflection transducer embodying the linear displacement amplification device for producing an electrical output representing the amplified input displacement.
A linear displacement amplification device comprising: a lever; first and second fulcrum means rockably engaging opposite sides of said lever in a common plane normal to the longitudinal axis of said lever; means restraining each fulcrum means against sliding movement along said lever; and means supporting said fulcrum means for relative movement in the endwise direction of said lever to cause lateral displacement of one end of said lever.

Claim 6
Dependent Claim
50 words
The device according to claim 1 wherein: said first fulcrum means comprises a pair of conical tapered fulcrum points engaging one side of said lever and said second fulcrum means comprises a single conical tapered fulcrum point engaging the opposite side of said lever between said pair of fulcrum points.
