TUNING-PIN SOCKET FGR STRINGED lNSTRUMENTS.
SPECIFICATION forming part of Letters Patent No. 533,492, dated February 5, 18945.
Application filed October 5, 1894. Serial No. 525,031. (No model.)
T0 aZZ whom it may concern:
Be it known that I, OLARANOE \V. PEOK, a citizen of the United States, residing at Elmira, in the county of Ohemung and State of New York, have invented a new and useful Tuning-Pin Socket for Stringed Instruments, of which the following is a specification.
My invention relates to tuning-pin sockets for pianos and similar instruments, and it has for its object to provide means whereby a pin may be used in connection with a metallic frame and whereby said pin will be free from a sounding vibration and will be held from slipping or loosening.
Further objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims. 7
In the drawings: Figure l is a perspective view of a section of a metallic frame, for a piano, provided with tuning-pin sockets embodying my invention. Fig. 2 is a plan view, showing some of the tuning pins and some of the friction pins displaced. Fig. 3 is a vertical section of a portion of the frame. Fig. 4 is a view of a socket in which the convex friction pins are formed integral with the plate.
Similar numerals of reference indicate corresponding parts in all the figures of the draw- 1ngs.
1 designates a metallic frame provided with main pin openings 2, and communicating with each of said openings are the twin juxtaposed friction-pin perforations 3, arranged at one side of the main opening and breaking thereinto. In the said perforations are fitted the small friction-pins 4, the sides of which project slightly into the main or tuning-pin opening, whereby when the tuning-pin 5 is arranged in said opening it bears at one side against the twin friction pins and at the opposite side against the side of the main opening. The strain of the wire 6 is in a direction approximately parallel with a line connecting the axes of the friction-pins, but is deflected from such line sufficiently to cause a somewhat greater pressure against the near or forward friction-pin. By this arrangement the tuning pin has three points of bearing, in the socket or opening provided for its reception, the remaining portion of the surface of the pin being out of contact with the adjacent metal, and therefore the vibration which may be imparted to the pin from the wire is not communicated to the frame with sufficient intensity to produce an audible sound. Furthermore, the effect of the peculiar arrangement of the points of contact is to wedge or crowd the tuning-pin between two of such points, namely, between one of the friction-pins and the opposite side of the main opening, and thus lock it against accidental rotation and displacement.
The means, as above described,forproviding the three points of contact, may be varied by forming the convex friction points, or friction-pins, integral with the frame, but it is obvious that with the arrangement described the process of construction is simplified, from the fact that the main openings and the auxiliary openings or perforations maybe drilled, successively, and the friction pins driven or fitted in said perforations subsequently, and therefore the described construction is preferred.
The essential feature of the construction is the provision of a socket for a tuning-pin, such socket having a concave bearing point and a plurality of convex bearing points arranged approximately opposite to the concave bearing point. It will be understood, moreover, that various other changes in the form, proportion, and minor details of construction may be resorted to without depart-- ing from the spirit or sacrificing any of the advantages of the invention.
It should be noted in connection with the above description, that the convex bearing points are arranged at that side of the tuning-pin from which the main portion of the wire extends, whereby the draft of the wire hasa tendency to turn the tuning-pin toward said convex bearing points.
Having thus described my invention, I claim 1. In a device of the class described, a frame having tuning-pin sockets or openings provided with convex bearing points, substantially as specified.
2. A frame having tuning-pin sockets properforations and projecting slightly into the main opening to form convex bearing points, substantially as specified.
In testimony that I claim the foregoing as 15 my own I have hereto affixed my signature in the presence of two witnesses.
CLARANCE W. PEOK.
