IMPROVEMENTS IN PIANO'S AND APPLIANCES CONNECTED THEREWITH
Year: 1885

page_text: I HENRY MORRIS of 3 The Grove, Hackney, Middlesex, Machinist, do hereby
declare the nature of my said invention for "IMPROVEMENTS IN PIANO'S AND
APPLIANCES CONNECTED THEREWITH" to be as follows :-
According to the first part of my invention, I make the back, or frame of a piano
of metal, with a chamber, or chambers, or pockets, in the upper part, with an
opening, or openings, through which the. strings can be passed and secured or
strained.
According to the second part of my invention, I construct detachable bridges,
(and preferably in sections) and affix them in a chamber, or chambers, formed in
the upper part of the back or frame, this being open to receive said bridge, or
sectional bridges, over which the strings or wires can be strained in any suitable
manner.
According to the third part of my invention I make the bridge or sectional
bridges of a series of partition plates, connected by a rod, or bar, provided or not,
with rollers between the partition plates. The strings or wires are guided over
the rod, bar, or the rollers thereon to any appliance by which they can be strained.
According to the fourth part of my invention I form on, or affix, a series of
projections on the lower portion of a back or frame and arrange on each projection,.
(which take the place of the ordinary hitch pins) a kind of parbuckle, with
a screw, by which the strings or wires in single, double, or triple order can be
secured and strained if desired.
According to the fifth part of my invention I attach the wires to pins, top and
bottom, of the metal frame, said wires passing over rollers, carried by the pins to:
constitute a trichord..
For a bichord the roller on the upper pin is dispensed with and the two ends of
the wire are attached to the two wrest pins the wire passing round the roller on
the bottom pin.
. According to the sixth part of my invention I bush the wrest pin holes and the
hitch pin holes of iron frames with wood or other equivalent material to enable
the pins to obtain a fair grip and to prevent a loosening or running back, such as
the pins are liable to, when inserted directly into iron frames in the usual manner.

page_text: 1 HENRY MORRIS of 3 The Grove,. Hackney, Middlesex, Machinist, 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 certain improvements in pianos and in the tuning pins
and appliances connected therewith, which will be understood by reference to the
annexed drawings.
According to the first part of my invention, I make the metal frame A of a
piano, with a chamber, or chambers, or pockets B, B, in the upper part with an
opening, or opening CC through which the strings D can be passed and secured
or strained as represented at Figures 1 and 2 which are a perspective view and
section respectively of part of the frame.
According to the second part of my invention, I construct detachable bridges EE
in sections, or consisting of a single steel bar and affix them in a chamber or
chambers B B formed in the upper part of the frame A, this being open to receive
said steel bar, bridge, or sectional bridges E E over which the strings or wires D D
can be strained in any suitable manner.
According to the third part of my invention, (shown in Figure 3 of the annexed
drawings) I make the bridge or sectional bridges EE of a series of partition
plates F F F connected by, a rod or bar E provided or not with rollers G, G, between
the partition plates F FF. The strings or wires D D are guided over the rod,
bar E or the rollers G thereon to any appliance by which they can be strained.
According to the fourth part of my invention, (see Figure 1) I form on, or affix
a series of projections H H on the lower portion of a frame A and arrange on each
projection, (which take the place of the ordinary hitch pins) a kind of parbuckle I
with a screw J by which the strings or wires D D in single, double, or triple order
can be secured and strained to pitch.
Figures 4 and 5 show two forms of the parbuckle I, that represented by Figure 4
being suitable for unichord, bichord, or trichord. In Figure 5 the parbuckle I is
rounded at the upper part and carries a roller K on a pin L. The string or wire D
passes round the roller K to constitute a bichord or trichord.
According to the fifth part of my invention, I attach the wires D. D. to, pins M M
top and bottom of the metal frame A said wires D D passing over rollers KK
carried by the pins M M to constitute a trichord as shown at Figure 6.
For a bichord, the roller on the upper pin is dispensed with and the two ends of
the wire are attached to the two wrest pins M.M the wire passing round the
roller K on the bottom pin M in the manner represented at. Figure 7.
According to the sixth part of my invention, I bush the wrest pin holes and
the hitch pin holes of iron frames with wood or other equivalent material to enable
the pins to obtain a fair grip and to prevent a loosening or running back.
Figure 8 represents the frame of a piano with all the holes for the wrest pins M M
having wooden bushes N N therein. The diameter of the wrest pin is larger than
that of the hole P through the wooden bush N so that the bush is compressed by
inserting the wrest pin which is thereby held firmly in position. Figures 9 and 10

page_text: are views of the wooden bush and wrest pin respectively. The wrest pin is
roughened in any suitable manner at one end Q the other end being shaped to
receive a key or instrument by which it may be turned for the purpose of tuning
or tightening the string or wire. Figures 11 and 12 show one of the wrest pins in
position in the wooden bush with and without the roller K respectively.
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. The improvements in Pianos and appliances connected therewith all as herein-
before described and shown in the annexed drawings.
2. Making the upper part of the metal frame of a piano with chambers or
pockets with an opening or openings through which the strings can be passed in
the manner described with reference to the first part of my invention and shown
in the annexed drawings at Figures 1, 2, and 3.
3. Arranging detachable bridges or steel bar in pianos in the manner described
and shown at Figures 1, 2, and 3.
4. Forming the bridge or sectional bridges of a series of partition plates con-
nected by a bar or rod and with or without guide rollers as herein before described
and shown in the drawings.
5. The arrangement of projections (in the place of bitch pins) each carrying
a parbuckle with or without a roller, the springs or wires being strained from the
bottom of the instrument by means of a tuning pin acting against said projection
in the manner herein described and shown in the annexed drawings.
6. Attaching the wires to pins and passing them over rollers to constitute an
improved bichord and trichord in the manner described and shown in the drawings
at Figures 6 and 7.
7. The employment in metal piano frames in connection with wrest pins hitch
pins or tuning pins or their equivalent substantially as described for the purpose
set forth.
8. The employment of the before mentioned improvements in any suitable com-
bination for the purposes set forth.
