Abstract
699,826. Pianofortes. GUICHARD & CIE. (MAISON ERARD). Jan. 18, 1951 [Jan. 18, 1950], No. 1411/51. Class 88 (ii). In a repetition action for an upright pianoforte, the pivotal axis of each hammer passes through that part of the hammer butt 10 which is furthest from the associated string and the jack 8 is arranged to engage the butt at a point above this axis, the hammer return spring 18 being in engagement with that part of the butt which is nearest the string. Various arrangements of the repetition spring 14 are shown in Figs. 1, 3, and 4. The back check 23 may be pivoted to the wippen 5 and acted upon by one arm of the repetition spring, Fig. 3. Each key 1 has a depending tail which acts on the wippen 5 either vertically, Fig. 1, or horizontally, Fig. 5. The keys may be pivoted on a common horizontal rod 49, Fig. 5. The action and keyboard are mounted on a common frame which is slidable sideways under the control of the soft pedal.
