FREDERICK GEORGE BILLINGS, OF MILWAUKEE, WISCONSIN.

PIANO-FLANGE ATTACI-IING-IBAR.

To all whom it may concern:

Be it known that I, FREDERICK BIL- LINGS, citizen of the United States, and resident of Milwaukee, Wisconsin, have invented certain new and useful Improvements in Piano-Flange-Attaching Bars, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to piano flange attaching bars, the object of my invention being to construct a simple, inexpensive and continuous metal bar which is readily attached to the main rail of a piano action, and in which metal bar is provided a slot which receives portions of the hammer butt flanges, which latter are detachably secured to the wood rail. By such arrangement, the main wood rail of the action is greatly strengthened and the flanges are kept in perfect alineinent by reason of their engagement with the continuous metal rail and the hammers and butts can readily be removed and replaced without destroying the perfect lineup of said parts.

To the above purposes, my invention consists in certain novel features of construction and arrangement of parts, which will be hereinafter more fully set forth, pointed out in the claims, and illustrated in the accompanying drawings, in which:

Figure l is a perspective view of a portion of the main rail of a piano action and showing my improved continuous metal bar positioned in said rail, and also showing a pair of flanges attached to the rail and bar; and Fig. 2 is a perspective view of a portion of the continuous metal bar.

Referring by numerals to the accompany ing drawings :1 designates the ordinary wood rail, which is in general use in upright piano actions, and formed in the front face thereof, adjacent the top, is a continuous longitudinally extendlng groove 2, of such size as to readily receive the continuous metal bar 3. This continuous bar 8, which occupies the groove 2, is preferably constructed of brass, or analogous metal, is rectangular in cross section, and extends from one end of the rail 1 to the other, and the outer face of said bar lies flush with the bar 3 and at suitable distances apart, are

apertures 4%., through which pass screws 5, which rigidly fix the bar on the rail 1, and formed in the front face of the bar between these apertures and the top of said bar is a continuous groove or slot 6, which is for the reception of lugs formed on the lower ends of the hammer butt flanges. These hammer butt flanges A, a pair of which is shown in Fig. 1, are arranged on the front face of the upper portion of the rail 1 with their laterally bent lower ends seated in the groove 6, and said flanges are detachably held on the rail by means of screws B, which pass through the butts of said flanges and enter apertures C formed in the rail 1 above the continuous groove 2 therein.

By my improved construction of rail, the flanges are held in absolute alinement while the screws B are being seated and tightened, and while the hammers and butts are re moved, replaced, or spaced; and the work incident to the removal and replacing of the hammers and butts can be readily and quickly accomplished by means of a screw driver. The metal bar stifiens and strengthens the wood rail and effectually prevents any material shrinkage and distortion of the central portion of said wood rail.

I claim:

1. The combination with a piano action rail, in the face of which is formed a continuous groove, of a continuous metal bar seated in said groove, there being a continuous groove formed in the face of said bar adjacent the upper edge thereof, and there being apertures formed through the body of the bar below the groove, which apertures receive the screws which fasten the bar to the rail.

2. The combination with the paino action rail, in the face of which is formed a continuous groove and there being a series of apertures formed in the rail above the groove, of a continuous metal bar seated in the groove in the rail, there being a continuous groove formed in the face of the metal bar adjacent the upper edge thereof, and there being apertures formed through the bar below the groove, which apertures receive the screws which fasten the bar to the rail.

3. The combination with the piano action rail, in the face of which is formed a continuous groove and there being a series of apertures formed in the rail above the which apertures receive the screws which 10 groove, of a continuous metal bar seated in fasten the bar to the rail.

the groove in the rail, the front face of In testimony whereof, I have signed my which metal bar lies flush with the face of name to this specification, in presence of the rail in which the apertures are formed, two subscribing witnesses.

there being a continuous groove formed in FREDERICK GEORGE BILLINGS. the face of the metal bar adjacent the upper lvltnessesz edge thereof, and there being apertures W. S. SMALLwooD,

formed through the bar below the groove, HENRY I. BLACK.
