Abstract

704,128. Pianofortes. VEGA, E. F., and CEJAS, E. E. Feb. 27, 1952, No. 5123/52. Class 88 (2). Spiral steel strings 23 are stretched between two bars 2 and 3 of brass or copper which are connected to an electricity supply. A magnetized bar 4 crosses the strings and has projections extending between them. Each string 23 has tuning devices 25 and 26 and is sounded by means of an associated hammer 12, which is thrown against the string by depression of a key 1 and rebounds to rest on a stub 15. The usual pedals 30 and damping mechanism are provided, but there is no soundboard or bridge.
