PIANO.
Specification hof Letters Patent.
Patented April 3, 1906.
Application filed December 26, 1905. Serial No. 293,174..
T0 all whom it may concern:
Be it known that I, WILLIAM D. CALLOW, a citizen of the United States, residing at Newark, Essex county, State of New Jersey, have invented new and useful Improvements in Pianos, of which the following is a specification.
This invention relates to an improved piano or similar instrument, and more particularly to means for increasing the volume of sound emitted and means for controlling said volume of sound.
In the accompanying drawings, Figure 1 is a front view of an upright piano embodying my invention. Figs. 2 and 3 are cross-sections through the upper part of the piano, showing the sound-reflector in different positions; Fig. 4,' a detail front view, partly broken away, of the upper part of the pianocase; Fig. 5, a detail of the latch, and Figs. and 7 are details of the stop-hinge.
The piano-case is provided with a front a, aback a', and a top a2. Below the top 0.2 there is formed in the front a, an open panel a3, adapted for the emission of sound. b represents .the usual iron frame, carrying the sound-board and arranged parallel to back a In order to deflect the sound and carry it forward through panel a3, there is provided below top a2 a curved plate or reflector c, havingarms c c2, fulcrumed to the pianocasing at c3. To the front of plate c there is secured by a hinge d a lid or fall e, which when swung down is adapted to close opening a3. The hinge d has a spring d', which by engaging a knuckle cl2 holds the fall e in its raised position, Figs. 2 and 6. The reflector c is maintained in its forward position by a catch f, engaging arm c2, Figs. 3 and 5.
Between frame l) and back a there is formed an upright chamber' g, which communicates with the open panel a3 by means of an upper sound-passage a4, formed below reflector c. When the reflector is in its normal position, Fig. 2, it projects over chamber g, so that the sound-waves flow from said chamber below the reflector and along sound-passage a4 out through open panel a3. When the plate c is swung forward and the lid e is drawn down to close panel a", the volume of sound emitted will be considerably reduced, so that in this way the volume of tone is readily controlled by the operator. The reflector may be operated by a lifter h from a pedal or by a pushbutton.
What I claim is- 1. A piano provided with a top, an open front, and a curved pivoted reflector below the top, substantially as specified.
2. A piano provided with a top, an open front, a pivoted reflector below the top, and a fall hinged to the reflector, substantially as specified.
Signed by me at New York city, (Manhattan,) New York, this 22d day of December,
WILLIAM D. CALLOW.
