PIANO SDUNDlNG-BOARD ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 252,146, dated January 10, 1882.

To all whom it may concern Be it known that I, JOHN G. SEEBOLD, of

vMontreal, Province of Quebec, Dominion t Canada, have invented a new and useful Improvement in Sounding-Board Attachments, of whichthe following is a specification.

The object of my invention is to provide a certain new and useful improvement in sounding-board attachments, whereby the quantity and quality of the tones will be augmented and equalized. I

The invention consists in the combination, with a sounding-board, of an upright stript'urnished with an aperture for each string between the bridge and the hitch-pin block, the strings resting against the upper edge of the apertures.

In the accompanying drawings, Figure l is a plan view of a sounding-board provided with my improvement. Fig. 2 is a longitudinal elevation of the same on the linem 00, Fig. 1; and Fig. 3 is a longitudinal elevation of the apertured metal plate constituting my improve ment in sounding boards.

Similar letters of reference indicate corresponding parts.

An upright strip of metal provided with an aperture, B, for each string is attached to the sounding-board 0 between the bridge D, and the hitch-pin block E, the strings M passing from the tuning-pins F F in the tuningpin block Gr, over the bridge D, through the aperture B of the plate or strip A, to the hitch-pins H on the hitch-pin block E. The upper edge of the apertures B is slightly lower than the bearing-surfaces of the bridge D and the hitch- Application filed April 26, [881. (ModeL) pin block E, so that the strings Will be inclined from the bearing-surfaces of the bridge and the hitch-pin block to the plate or strip A, and will rest against the upper edge ofthe apertures and will press upward, whereas the strings press downward on the ordinary soundingboard bridge.

The strip A may be made in one continual piece extending across the entire soundingboard, or may be made in sections in order to suit theparticular scale.

The strip A may be'fastened in any suitable manner, but I prefer to provide it with clips or lugs J J at the ends, (also in the middle,) which clips are passed through slots in the sounding-board and are bent over on the under side of the same, as shown in Fig. 2. This strip A is applicable to any stringed musical instrument. The sounding-board cannot sag between the bridge, and there is a continual tension on the strip which vibrates with the sounding-board and muitiplies the vibrations, thus augmenting the quantity and quality of the tones, giving them richness and fullness.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent of the strings M, the bridge D, the hitch-pin block, and the apertured strip A, provided with clips, all arranged substantially as and for the purpose specified.
