SILENCING STOP FOR THE HAND OR FOOT FOR SUBDUEING THE SOUNDS

"
OF
At the right or left hand side of the keys of a pianoforte placed a small knob
which on being drawn forward acts upon certain mechanism within the piano so
as to introduce a slip of silk, velvet felt or other woolen material across the strings
thereof in front of the hammers and immediately the sound or tone is subdued
producing the most agreeable sensation possible.
Parallel with the knob is a sliding bar and spring terminated at the back of the
keys with a quadrant or crank at right angles with which is an upright connecting
rod attached to a semicircular brass plate which at each end is connected first with
a fixed block and then with a bar of metal or wood, holding silk, velvet, felt or any
other woolen material before the strings and in front of the hammers terminated
by another semicircular brass plate upon a fixed block the whole of which said
machinery I claim as my invention.
I do not limit myself to the above minute details, as many different pianos may
require different treatment to produce the same effect and some may require it as a
foot stop or both hand and foot combined but at the same time being quite
independent of and not interfering with any other parts of pianoforte actions or
pedals whatsoever.

page_text: I ABRAHAM DIMOLINE Pianoforte Maker No 41 Leigh Road South Clifton,
Bristol, do hereby declare the nature of my said invention for "A PIANOFORTE
SILENCING STOP FOR THE HAND OR FOOT FOR SUBDUING THE SOUNDS OF
PIANOFORTES WHILST PLAYING THEREON," 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 certain means and apparatus for subduing and
modifying the sound of pianofortes as will be clearly understood by the annexed
drawings.
At the right or left band side of the keys.A (see Figures 1 and 2) of a piano- i
forto B is placed a small knob C. which on being drawn forward acts upon certain
mechanism within the piano so as to introduce a slip D of silk, velvet, felt or
other woollen material across the strings thereof in front of the bammers E and
immediately the sound or tone is subdued producing the most agreeable quality
possible.
In a line with and connected to the knob C is a sliding bar F and spring G
terminated at the back of the keys with a quadrant or elbow crank H at right
angles with which is an upright connecting rod I attached to a semicircular or
other shaped brass plate J of which there are two, one at each end connected first
'with a fixed block K and then with a bar L of metal or wood holding the silk,
velvet, felt or any other woollen material D before the strings M and in
front of the hammers E when the knob C is pulled out as shown in Figure 2.
On pushing in the knob the slip of silk, or other material is lowered to the position
shown in dotted lines in Figure 1.
I do not limit myself to the above minute details, as many different pianos may
require different treatment to produce the same effect and some may require it as a
foot stop or both hand and foot combined but at the same time being quite independent
of and not interfering with any other parts of pianoforte action or pedals whatsoever.
In Figures 1 and 2 the foot stop or pedal N which could be arranged in any
suitable position would have its rod P attached to the upright connecting rod I
(the knob C and its connections being dispensed with) if it were desired to have a
foot stop only.
If hand and foot stops combined were required, the rod P would be loosely
connected with the crank H.
Figure 3 shows a side elevation and Figure 4 a front elevation of the mechanism 3
to a larger scale.
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:
-
The improved silencing stop for pianos arranged in the manner set forth and as 4
shown in the annexed drawings.
