UNITED STATES PATENT OFFICE.
ALBERT IIABTENSTIN, OF INDIANAPOLIS, INDIANA.
IMPROVEMENT IN UPRIGHT PIANO-FORTES.
Specilication forming part of Letters Patent No. 149,307, dated April 7, 1874; application filed June 28, 1873.
To all whom it may concern:
Be it known that I, ALBERT HARTENSTEIN, of Indianapolis, in the county of Marion and State of Indiana, have invented certain Improvements in Piano-Fortes, of which the following is a specitication:
My invention relates to that class of pianos known as upright square; and it consists in the construction and arrangement of the bridge over which the strings pass to the tuning-pins, the objectbeing to both cheapen the bridge, and at the same time to provide for overstringin g in such a manner as to bring the greatest practicable number of strings to the middle of the sounding-board, as well as securing a greater length ot' string, and thereby greatly increasin g the tone and power ot the instrument within a small space. v
Figure lis a front elevation of the frame and sounding-board of an upright piano embodying my invention. Fig. 2 is a top edge view of the saine.
A is the cast-iron frame now usually employed to sustain the strings. B is the bridge near the top of the frame, over which the strings pass to the tuning-pins C, the latter being arranged in the top edge ot' the frame, as shown, so as to allow the bridge B to be placed at the top edge of the trame, and thereby increase the length of the strings. The bridge B is cast with and made part of the frame A, though it may be made in a separate piece7 and is divided into three sections, O O' 0, constructed and arranged as clearly shown in the drawing, the sections O O having notches on the edges, as shown, through which the diagonal strings D E pass to the tuningpins C.
The advantages claimed for this construction and arrangement of the bridge B are cheapness, together with comparative freedom from fretting of the strings where they pass through the notches.
The arrangement of the pins C possesses an additional advantage in the facility and convenience with which they may be turned, by means of a suitable key, in tuning the instrument. The plain section O of the bridge is the part that the short strings pass over.
I claim as my invention- The bridge B, provided with the sections O O O, in combination with the frame A and tuning-pins C, all constructed and arranged substantially as and for the purpose set forth.
ALBERT HARTENS'IEIN.
