BUSHING FOR PIANO TUN ING-PIN S.

Speccaton of Letters Patent.

Patented Apr. 30, 1918.

Application filed May 19, 1915. Serial No. 29,122.

To all whom t may concern: l

Be it known that I, HARRY BAYER, a citizen of the United States, residing at Poughkeepsie, in the county of Dutchess and State of New York, have invented certain new and useful Improvements in Bushings for Piano Tuning-Pins, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvement-s in pianos, and more particularly has reference to means for securing the piano wires or strings in position.

Referring to the accompanying drawings, Figure 1 illustrates a broken section of a portion of a piano embodying an application of my invention. Fig. 2 is a cross section on the line 2 2 of Fig. 1. Fig. 3 is a perspective view of one of my metallic bushings, and Fig. 4 a perspective view of one of the usual form of wooden bushings.

5 indicates the usual iron frame or string plate over which the strings are secured, and 6 the tuning pins to which the strings are secured. 7 indicates the usual wrist plank to which the iron plate 5 is secured and into which the pins 6 penetrate, said pins being provided with the usual iine thread indicated by the reference character 8. 9 indicates the usual form of wooden bushing shown to better advantage in Fig. 4L which usually fits into the hole in the iron plate 5 and through which pins such as 6 are secured.

It has been found that by forming a metallic bushing such as 10 substantially as shown in Fig. 3 with an outer flange or rim such as ll, and by iitting the same within the hole in the iron plate 5 before applying the wooden bushing such as 9 that a better construction is obtained. These metallic bushings are preferably formed out of sheet brass of such a size that the wooden bushings snugly and tightly lit therein and so that the metallic bushings snugly and tightly engage the hole in the iron plate 5. When the pin 6 has been secured therein as shown in Fig. 2 the likelihood of the same coming loose is actually reduced to a minimum, and the wooden bushing 9 is better secured in place. The arrangement also contributes to a more finished appearance as Well asto the quality of the instrument and durability of the same. The strings 12 are of course passed through the pins 6 and wound thereupon in the usual manner.

Of course it will be understood that various modifications may be made without departing from the spirit of the invention as claimed.

I claim:

1. In combination with the string plate and tuning pins of a piano, a bushing through which each pin passes, and a bushing between said first mentioned bushing and the walls of the hole in said plate within which said bushing is seated.

2. In combination with the string plate and timing pins of a piano, a bushing through which each pin passes and a metallic bushing between said first mentioned bushing and the walls of the hole in said plate within which said metallic bushing is seated, said metallic bushing having a flange extending over the edge of the wall in said plate.

3. Bushings for the tuning pins of a piano comprising a straight walled tubular wooden member through'which the pin passes and an outer tubular metallic member within which said tubular wooden member is seated, said outer tubular member having an outwardly extending flange. y

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
