UNITED STATES PATENT FFICE.
HENRY BEHNING AND {JUS'IUS DIEHL, OF NEW YORK, N. Y.
IMPROVEMENT IN PIANO-FORTE AGRAFFES.
Specification forming part of Letters Patent No. 154,116, dated August 18, 1874; application filed July 17, 1874.
To all Vwhom t may concern:
Beit known that we, HENRY BEHNING and JUsTUs DIEHL, both of New York city, county and State of New York, have invented certain Improvements in Piano-Fortes, of which the following is a specification:
The object of our improvement is to provide for an improved agrai'e in the construction of piano-fortes, by aid of which a clearer and fuller tone is obtained, and which also greatly facilitates the tuning ofthe instrument, keeping it longer in tune and preventing the breaking or snapping of the strings. Our invention consists in forming an elevated rest on the shoulder of the agral'e nearest to the stringf keys, and on the top of this rest notches or indentures are cut, in which the strings lie. The agrail'es are placed in the wood or metal in the ordinary manner, and the strings are passed through a hole or holes cut in the head of the agrai'c according to the number of strings. It is evident that the agratfes by this arrangement are held down to the sounding-board instead of being in danger of being forced out by the tightening of the strings.
In order to describe oui` invention more fully, we refer to the accompanying drawing forming a part of this specification.
Figure I is a plan view of a sounding-board, showing the improvedagraife attach ed thereto. Fig. II is a side view ofthe same. Fig. III is a detached side view of our improved agraie. Fig. IV is a plan view of the same.
A is the sounding-board, and into which, or into the wrest-plank, is screwed, at a, the a-gratfe B. b is the shoulder. b1 is the head, with holes b2. C is the elevated rest on the shoulder b, with indentures c. D is the string, and E the string-key; g, the threads on the lower part of the agrafe.
Having thus described our invention, we desire to claim- The agratle for piano-fortes herein described,
consisting of the body B, screw-threaded portion g, perforated head b1, and elevated rest C, all constructed and arranged as and for the purpose specified.
This specification signed this 7th day of July, 1874.
HENRY BEHNING.
JUSTUS DIEHL.
