PROVISIONAL SPECIFICATION.
Improvements in the Bass Bars or Sounding Bars of Violins and
the like.
I, LOUIS LÖWENTHAL, of Reichenbergerstrasse, Berlin, Germany, Manufac-
turer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to bass bars or sounding bars for augmenting
the tone of bow played string instruments and which consist of a bar or rib
arranged on the sounding board or belly inside and lengthways of the instrument.
Such bars have hitherto been made solid, but in this invention with the object
of producing a finer and fuller tone than is practicable with solid bars, such bars
are provided with holes in which are fixed hollow cross pieces of any con-
venient cross section such as cylindrical, triangular, etcetera, thus forming a
branched system which vibrates with the sound waves.

Improvements in the Bass Bars or Sounding Bars of Violins and
the like.
I, LOUIS LÖWENTHAL, of Reichenbergerstrasse, Berlin, Germany, Manufac-
turer, 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 has reference to bass bars or sounding bars for augmenting
the tone of bow played string instruments and which consist of a bar or rib
arranged on the sounding board or belly inside and lengthways of the instru-
ment. Such bars have hitherto been made solid, but in this invention with the
object of producing a finer and fuller tone than is obtainable with solid bars,
such bars are provided with holes in which are fixed hollow cross pieces of
any convenient cross section such as cylindrical, triangular, etcetera, thus forming
a branched system which vibrates with the sound waves.
In order that the invention may be fully understood it will now be described
with reference to the accompanying drawings in which:

of the sounding-tubes.
Figure 4 is a vertical section through a violin representing the arrangement
of the sounding bar on the sounding board or belly inside and lengthways of
the instrument.
d Figure 4 represents a violin and e the sounding board or belly of the same.
a is a sounding bar attached in any convenient manner lengthways on the inside
of the sounding-board or belly c. The mentioned sounding-bar is provided with
a number of holes b in which are fixed as sound-catchers, hollow cross pieces of
any convenient cross-section, preferably cylindrical or conical, thus forming a
branched system which vibrates with the sound waves. These cross-pieces can
be arranged in all or only part of the holes according to the tone desired, and
be hollow or solid.
By means of this new sounding-bar, the sounding-waves of the bar are aug-
mented to such an extent that not only the tone of the instrument becomes
much louder and fuller but also the harsh quality of the sound is moderated.
Besides this the three open sound-catchers arranged in the holes are of great
benefit to the sound waves because they augment the vibration of the sounding-
bar and transfer the timbre, of the sound upon all 4 strings.
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:-
Improvements in bass bars or sounding bars of violins and the like as well as
other bow played string instruments, consisting of a bar or rib arranged on the
sounding-board or belly inside and lengthways of the instrument and provided
with holes in which can be fixed hollow cross-pieces of any convenient cross-
section such as cylindrical, triangular etcetera, thus forming a branched system
which vibrates with the sound-waves for the purpose of producing a finer and
fuller tone than is obtainable with solid bars hitherto in use.
