Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
222 words
Apparatus for the measurement of mechanical work and performance transmitted by means of a flexible transmission element between two guide wheels, including: (a) a first roller, said first roller being placed under a load, acting on one side of said transmission element and deflecting said transmission element in accordance with said load and with the traction in the transmission element; (b) a second roller acting on the other side of said transmission element; (c) a first device for measuring the deflection of said first roller and for producing a corresponding first signal; (d) a second device for measuring the distance covered by said transmission member and its speed of travel, and for producing a corresponding second signal; (e) one of the group of elements comprising said guide wheels and rollers comprising a sensor; (f) a third device controlled by said first and second signals for producing a third signal corresponding to the said mechanical work and performance; (g) said first and second rollers being supported on a structure which is swingably supported on the axis of one of said guide wheels and wherein said structure includes a holder swingably positioned on the axis of one of the guide wheels joined by the transmission element, and a lever swingably positioned on the holder, at least one said roller being positioned on said lever.
