OIIRISTIAN LUDWIG OSKAR ALTENBURG, OF NEW YORK, N. Y.
TREBLE-BRIDGE FOR PBANOS.
SPECIFICATION forming part of Letters Patent No. 529,994, dated November 2'7, 1894.
Application filed September 25, 1894- Serial No. 524| (N0 modem To aZZ whom it may concern.-
Be it known that I, CHRISTIAN LUDWIG Os- KAR ALTENBURG, of New York city, in the county and State of New York, have invented a new and Improved Treble-Bridge for Pianos, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved treble bridge for pianos and similar stringed musical instruments, and arranged in such a manner that when the short treble strings are struck by the hammer, they give a full and sweet sound.
The invention consists of a bridge supported at one end, and over the free end of which pass the treble strings.
The invention also consists in certain parts and details, and combinations of the same, as will be hereinafter fully described and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the views.
Figure 1 isaplan view of the improvement as applied. Fig. 2 is a sectional side elevation of the same, on the line 2-2 of Fig.1; and Fig. 3 is a transverse section of the same, on the line 3-3 of Fig. 1.
The piano or other similar musical instrument is provided with the usual string frame A, carrying besides theother strings, the treble strings B, attached at one end to the pins 0, and at their other ends to the wrest pins D, adapted to be turned in the usual manner for tuning the strings. The treble strings B after leaving the fixed pins 0, pass over the sounding board bridge E, and then extend to and over the free end of a bridge F, secured at its rear end F in the frame A, the said free end extending in the opening A of the frame, and over which pass the strings. This treble bridge F is removable from the frame A, and is for that purpose provided at the bottom of its rear end F with a foot F extending under a projection A of the frame A, as plainly shown in Fig. 2, the said rear end F of the bridge extending into a recess Lugs F on opposite sides of the bridge F, and a short distance from the rear end, rest in recesses A formed in the top of the frame A, so that the bridge F is properly supported in the recess and extends with its outer end freely into the opening A, to carry the treble strings as previously mentioned. By this arrangement, the lugs F really form a fulcrum for the free end of the bridge to swing on, so that when the treble strings B are struck by the hammers the said strings can vibrate fully to produce a full and sweet sound, instead of the harsh sound now obtained in pianos of ordinary construction.
The top of the bridge F is preferably concave, as indicated in Fig. 3, and a longitudinally-extending bar G is secured in this top, to press the strings B in contact with the edges F, F of the bridge F, as plainly indicated in Fig. 3. The treble strings B after leaving the edge F pass over the usual bridge H, and under the bar I, to then wind on the wrest pins D, the said bridge II and bar I being held in the frame A. Now it will be seen that by the construction described, the free end of the bridge F on account of vibrating with the strings when the latter are struck by the hammers permits the strings to fully sound so as to produce a sweet tone. By reference to Fig. 1, it will be seen that the distance between the sounding board bridge E and the bridge H is very small, and only sufiicient room is had forthe hammers to strike the treble strings at about the line 2-2 marked in Fig. 1. The strings of ordinary pianos when struck by the hammers, have a harsh sound, while with my improved and free swinging bridge F, the strings will produce a clear and full sound.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A stringed musical instrument, provided with a treble bridge supported at one end, and having the treble strings passing over its free vibratile end, substantially as shown and described.
2. A stringed musical instrument, provided with a string frame for carrying the strings, and a treble bridge adapted to be fastened at one end on the said frame and extending with its free end into a recess in the frame, the said free end forming a resting place for the treble strings as the latter pass from the sounding board bridge to the frame bridge, substantially as shown and described.
