Device for adjusting a retrograde clock display.

摘要

The invention relates to a retrograde display mechanism comprising a plate and a rake (1) pivoting at the level of a first shaft around a first axis centering its teeth (2). A probe (3) of the rake (1) follows a cam (4) pivoting at a second shaft around a second axis. The position of the first axis and / or the second pivot axis is adjustable in position relative to the plate by means of an adjustment plate (30) carrying the first and / or respectively the second shaft, and movable with at least a degree of freedom with respect to the plate. The position of the adjustment plate (30) relative to the plate is adjustable by an adjustment control means (50) such as an eccentric screw (51) fixed on the plate and cooperating with a notch (52) of the adjustment plate (30), or vice versa. The invention is used to adjust the travel of a retrograde display driven by the display gear (21).
