Abstract
Abstract In order to attain a defined braking action, a measuring band brake device has a brake band which surrounds the brake drum through more than one turn of the same, one end of the band being free and having applied at said end a measuring force which alone decides the braking force.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
156 words
In a measuring band brake device intended for attaining a defined braking action, a frame, a braking drum mounted on said frame, a braking band having two ends and surrounding said drum at an encircling angle φ, the improvment comprising: means for applying an outmeasuring force at one end of the braking band, the other end of the band being affixed to said frame, means allowing movement of at least one end of the braking band, and means to drive the braking drum by a human being in order to out-measure the force exerted by said human being, the braking band surrounding the brake drum through more than one turn of the drum at an encircling angle φ at which the force at the affixed end of the band is negligible thus enabling the force exerted by the human being to be defined solely by the outmeasuring force applied at one end of the braking band.
Claim 2
Dependent Claim
156 words
In a measuring band brake device intended for attaining a defined braking action, a frame, a braking drum mounted on said frame, a braking band having two ends and surrounding said drum at an encircling angle φ, the improvment comprising: means for applying an outmeasuring force at one end of the braking band, the other end of the band being affixed to said frame, means allowing movement of at least one end of the braking band, and means to drive the braking drum by a human being in order to out-measure the force exerted by said human being, the braking band surrounding the brake drum through more than one turn of the drum at an encircling angle φ at which the force at the affixed end of the band is negligible thus enabling the force exerted by the human being to be defined solely by the outmeasuring force applied at one end of the braking band.
Claim 3
Dependent Claim
34 words
A device according to claim 1, in which the force at said affixed band end, by choice of the angle φ, is adjustable to compensate for transmission losses by movement of point of affixation.
