摘要： An augmented bass hammer striking distance is provided in both upright and grand pianos. At least those strings in the bass section having an optimum striking distance (d) to speaking length (L) ratio (d/L) of a value greater than 1/7 have their hammers located at a striking distance (d) along their lengths as determined by their optimum d/L value. The hammers of all of the bass section strings can be so located. Alternatively, the hammers of those bass section strings having an optimum value of d/L of 1/7 or less can be conventionally located at the same striking distance (d) determined from a preselected d/L value falling within the range of 1/7 to 1/9, or can be incrementally varied. When the lowest few strings of the bass section appear to have subjectively less apparent fullness of tone, the striking distance of the lowest few strings can be shortened string-by-string toward the low end of the bass section by amounts which will modify their subjective d/L - dependent pitch in 100-cent increments. When it is desired to have a rapid and smooth transition from a first group of strings in the bass region having d/L values greater than 1/7 to a second group of strings in the bass section having d/L values of 1/7 or less, the highest few strings of the first group can have their striking distances (d) shortened string-by-string toward the high end of the bass section by amounts which will modify their subjective d/L - dependent pitch in 100-cent increments.
摘要翻译： 直立和三角钢琴都提供了一个增强的低音锤撞击距离。 至少那些具有大于1/7的值的最佳打击距离（d）至说话长度（L）比（d / L））的低音部分的琴弦的锤子沿其长度位于打击距离（d） 由其最佳d / L值确定。 所有低音部分琴弦的锤子都可以如此定位。 或者，具有最佳值d / L为1/7以下的那些低音部分弦的锤可以通常位于从预选的d / L值确定的相同的击打距离（d） 7到1/9，或可以逐渐变化。 当低音部分的最低几弦似乎具有主观上不太明显的音调时，最低几弦的击打距离可以逐个缩小到低音部分的低端，数量将修改其主观 d / L依赖音高，以100分为单位。 当希望从具有d / L值大于1/7的低音区域中的第一组弦的快速平滑过渡到具有d / L值为1/7的低音部分中的第二组弦 或更少，第一组中最高的几个弦可以有其惊人的距离（d）逐字串缩小到低音部分的高端，这将以将以主观的d / L依赖音调修改为100分 增量。

摘要： A plastic damper for attachment to a vibrating piano wire, the damper consisting of a single piece part having an end slot for turning by a screwdriver, and communicating peripheral slits for receiving the piano wire. One end of each peripheral slit has a slightly greater width than the rest of the slit, so that the piano wire can be inserted through this end of the slit, and locked against the damper by rotating it with a screwdriver, so that the relatively narrow major part of the slit "twist-locks" against the wire; the slight resiliency of the plastic facilitating the "twist-lock" action.

摘要： A keyboard musical instrument is provided which comprises a main body which has a playing position and an upright position and first and second legs which are positioned on the front and rear of the main body for supporting the main body in the playing position. A hinge device connects the main body and the first legs such that the main body is pivoted about the hinge means for moving the main body between the playing position and the upright position.

摘要： Pedal actuator and connection assemblies for electronic vorsetzer player piano units incorporating universal connection members between the electronic assemblies and foot pedals for converting a conventional piano to an electronic player piano are disclosed. The connection assemblies include a foot member, one for each foot pedal, which are adapted to transmit actuating forces transmitted from the player piano unit downwardly and on the rear portion of the pedal member pivoting the foot member in the second ball joint to cause an upward force on a lower pedal-engaging surface to thereby engage the lower side of the pedal therewith and thereby permit upward and downward movement of the foot without it slipping off the pedal. At the same time, since there is no positive securement of the connection assembly to the foot pedal, the vorsetzer may be easily and quickly positioned on the piano for converting a standard piano to an electronic player piano.
