1 Claim. 1

Thi invention relates to wire tightening devices, and more particularly to the provision of a device for tightening the wire strings of a piano.

It is an object of the invention to provide a tool for tightening a knot for joining parts of of a wire when the Wire breaks between a piano bridge and a tuning pin.

A further object is to provide a wire tightening device which is simple in structure and easily applied, the device being of a nature that enables it to be conveniently carried.

These and other objects are attained by the novel arrangement and construction hereinafter described and illustrated by the accompanying drawings, forming a part hereof, and in which:

Fig. 1 is an elevational view of a sounding board with the wire tightening device embodying the invention.

Fig. 2 is a plan view of the wire tightening de vice.

Fig. 3 is a side elevational view of the tightening device.

Referring to the drawings, in Fig. 1 are shown horses I, upon which are supported a piano back frame 2, a back 3, and a sounding board 4, and. a tuning block 5. A string 6 which has been broken and rejoined by tying the broken ends together by a knot (in is attached at one free end to the tuning back frame 2.

The wire tightening device is shown to comprise a tubular member 8 having one side out out to fit over a tuning pin 1. The tubular member 8 is integral with or connected to a bar 9 having projecting up therefrom a staff ID with a handle I I, the staff being provided with a hole 12 adapted to receive the other free end of the wire 6.

Initially, the latter end of the wire is tightened about the staff In with the portion l3 of the bar at the left of the tuning pin 1 as shown in Fig. 3. The final tightening of the Wire is accomplished by rotating the handle portion l3 to the right as shown in Fig. 1, thus enabling fine adjustment.

The tightening device is obviously simple in structure and readili applicable to a tuning pin and easily removed so that it can be quickly applied to different wires of a piano.

The above description is to be considered as illustrative and not limitative of the invention, of which modifications can be made without departing from the spirit and scope of the invention as set forth in the appended claim.

The invention having been described, what is claimed is:

In a wire tightening device, a bar having a handle portion and a mounting portion, said portions lying in parallel planes in offset relation to each other and extending in opposite directions from each other and an inclined portion joining said first mentioned portions at their inner ends, a tube connected to the outer end of the mounting portion of the bar, in depending relation thereto, said tube having one side thereof cut out to fit over a tuning pin of a piano so that said bar can be rotated on the pin, a staff projecting from the mounting portion of the bar in vertical relation thereto adjacent to the inclined portion in offset relation to the vertical axis of the tube, said staff having a hole therein above the mounting portion of the bar to receive an end of a wire and a handle for rotating the staff until the preliminary tightenin of the wire is accomplished and final tightening of the wire may be accomplished upon movement of the handle portion of the bar in the same direction as the handle has been rotated.
