Lette/rs Patent No. 93,473, dated August 10, 1869.
IMPROVEMENT IN PIANO-PORTES:
The Schedule. referred to in these Letters Patent and making part of the same.
To all whmn it may concern Be it known that I, CHARLES A. PETERSON, of the city of New York, lin the county vand State vof- New York, have invented a new and improved- Piano-Forte; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the ar'. to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which my invention relates to piano-fortes; and- Itlconsists in an improved construction and armngement of the agrades, and a novel substitut-ion for the ordinary bridge, as will be hereinafter set forth.
In place of the ordinary bridge, I use a single plate, I
or a series of plates, I I, having two agraffes, J, and a block, K, for each chord, 'each block K being between a pair of agiaes, as shown.
These plates I arelfastenedY to the sounding-board by means of bolts or screws, c, or in other suitable manner.
By this arrangement the bridge, so to say,- can be shifted, to lengthen or shorten the vibrating poition of each chord, in order to produce the requisite sound.
Better harmony and clearness of sound can thus be obtained. By having both ends of the vibrating p0rtiou of each chord supported in equal manner, the chords will not be apt to vwear more at one end, and the strain will be equalized. Furthermore, if any one pmt of the apparatus shouldget out of order, it can be repaired without disturbing the other parts. The sounding-board will be less obstructed, and will be alle to vibrate more freely.
Having thus described my invention,
What I claim as new, and desire to secure by Letters Patent, is-
lhe' plates I, having the supporting-studs c, formed on their under sides, and provided on their upper surface with the agraiies J and central block or wire-rest K, all constructed and arranged as herein shown and,
described, and for the purpose set forth.
CHARLES A. PETERSON;
NVitnesses:
FRANK BLoonLnv, C. L. formi-1a.
