Abstract

The escapement is for an upright piano, having a second tappet (14) fixed to the arrester (9) and extending in the direction of the hammer sleeve. The distance between the end of this tappet (15) and the sleeve is such that the latter comes to bear against it roughly at the same time as the mating member (10) strikes the arrester. The second tappet can be fixed to the arrester by a spindle (16) allowing it to tilt so that its end lifts. The angle formed by the hammer sleeve, the straight line through the spindle and the point of contact between the tappet end and the spindle is approximately a right angle.
