Improvements in Stringing Pianos.
I, LOUIS ALBERT KINDLER, of 101 Bridge Street, Cleveland, in the County of
Cuyahoga and State of Ohio, United States of America, Piano Tuner, do hereby
eclare the nature of this invention and in what manner the same is to be
erformed, to be particularly described and ascertained in and by the following
tatement:-
This invention relates to the stringing of pianos and the means of regulating the

I, LOUIS ALBERT KINDLER, of 101 Bridge Street, Cleveland, in the County of
Cuyahoga and State of Ohio, United States of America, Piano Tuner, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to the stringing of pianos and the means of regulating the
tension of the strings for tuning; and it consists in the novel construction and
combinations, as hereinafter described, and pointed out in the claims.
In the accompanying drawings.
Figure 1 is a front elevation of a part of a frame having a few strings, showing
my improvement.
Fig. 2 is a longitudinal section of the same.
Fig. 3 is a view of one of the adjusting-screws.
A represents a metal frame, which may be of any of the well-known forms.
B B are the strings, which are looped and attached at both ends to hitch-
pins b b.
C is a metal bridge-frame firmly secured across one end of said frame A, in
which the hitch-pins for one end of the strings are placed. In the clevated portion
of said bridge-frame are arranged adjusting-screws D D, in staggered position to
admit of close arrangement of the strings.
The screws D D are provided on their lower ends with swiveled nuts d d, having
notches in their faces for catching and holding the strings, and the screws have
square or sexagon heads for convenience of turning them. Through said bridge C
are made holes or slots in conjunction with each screw-hole, through which the
strings are passed in stringing, so that the adjusting-screws may bear upon the
strings for regulating their tension. The bridge-frame is also provided with a
flange E, having perforations, through which the strings are also passed.
F is a sounding-board bridge.
From the foregoing it will be seen that the tension of the strings is readily
adjusted by the said screws D pressing upon and stretching them to any degree
desired.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a piano-stringing device, the combination, with bridge-frame C, having
agraffe E integral therewith, and having the staggered screw-holes, provided with
slots for the strings B, of the screws D, having swiveled nuts d, as and for the
purpose specified.

page_text: 2. The combination of frame A, strings B, bridge-frame C, having staggered
screw-holes and slots, adjusting-screws D, having swiveled nuts d for regulating the
tension of the strings, substantially as and for the purpose specified.
Dated this 11th day of August 1891.
