Abstract (en)
[origin: ES8300634A1] A tackle block for a cord having a rotatable pulley mounted on a shaft between a pair of legs, there being first and second pulleys mounted on a part of the shaft which is exterior of said legs. A guide sheath formed of a pair of arms is associated with the first pulley and the space between each of the arms and the groove of the first pulley is a minimum necessary for a cord of a certain diameter. The second fixed pulley has its inner plate slidably mounted on the shaft and resiliently biased toward said inner plate, with the inner plate being formed of a material which presents a large amount of friction to the cord. A guide means in the form of a pair of arms, each having a notch is provided on the outer face of the movable plate of the second fixed pulley to lock the cord. A braking shoe is mounted in a movable manner below the rotatable pulley to engage the rotatable pulley.
