Abstract: An electrical outlet box having improved mounting means for enabling the box to be mounted in an opening of a wall with the open front of the box being essentially flush with the front face of the wall. The mounting means includes a pair of mounting elements extending outwardly from the open front of the box for engaging the front face of the wall together with a U-shaped resilient clamping member which is mounted exteriorly of the box so as to span the box with a connecting or base portion and two depending legs which extend therefrom toward the open front of the box with the legs adapted to engage the rear face of the wall surrounding the opening therein. A connection device, such as a screw, interconnects the floor of the box with the leg connecting portion of the clamp and it serves to vary the distance between the floor of the box and the connecting portion of the clamp to cause the leg portions to move toward the front thereof and engage the rear side of the wall.

Abstract: A piano construction providing significantly improved tonal quality and balance by utilizing a soundboard which is tightly coupled to the string frame along the top edge and the two side edges of the soundboard except for a loose coupling adjacent the end of the bridge in the treble section along one of the side edges and which soundboard is loosely coupled along the lower edge as the latter is normally positioned in an upright piano. Additionally, a massive support rib on the string frame adjacently extends along the top edge of the soundboard to improve tone, and the strings at their upper ends are held in V-notches at tangential points about the string circumference to avoid lateral vibration. The string frame and soundboard are designed to produce a partially free diaphragmatic-type operation free of soundboard dead spots which maximizes tonal qualities for the dimensional restrictions of small pianos.
