AN IMPROVEMENT CONNECTED WITH STRINGING MUSICAL INSTRUMENTS to be as follows:
Year: 1884

page_text: I THOMAS JAMES BRINSMEAD of the firm John Brinsmead and Sons, 18 Wigmore
Street, in the county of Middlesex Pianoforte Manufacturers do hereby declare the
nature of my said invention for "AN IMPROVEMENT CONNECTED WITH STRINGING
MUSICAL INSTRUMENTS to be as follows:-
"
The object of this invention is, to secure the ends of wires or strings of stringed
musical instruments to the outer or more distant ends of screw pins by lodging
such wires or strings within the body or within a channel formed in the outer
portion of the whole or of a part of the length of the screw pin and in such
a manner that the nut by which the necessary tension can be put upon the wire or
string does not rub or bear against it. In connection with said recessed, grooved,
channelled or other shape of screw pin I use a collet provided on its inner surface
with a feather which engages in a groove of the pin to prevent the pin turning
round and twisting the wire or string when the nut is operated upon, a stud boing
also formed on the underside of the collet to engage in a hole or notch in the wrost
plank to hold it secure thereto.
For the purpose of my invention I form a hole longitudinally through the centre
or a groove along the outside of a screw pin and a short slot on the side diametri-
cally opposite to said groove or channel or I form a flat or other shaped surface on
or to such a pin and I drill another hole at right angles near the outer end of said
screw pin into which the wire or string can be laced or inserted after being bent
preferably over the outer end of the pin to secure the wire in position I purpose
fitting a cap over the outer end of the pin and the bent over portion of the wire
or string to lock the same in place, the wire or string being enclosed and covered
by the cap.
I also use a collet of washer shape with a feather on its inner face to engage in
the groove or channel or otherwise formed longitudinal slot or groove, the feather
being so shaped that it does not chafe the wire or string. Tho outer diameter of
the collet may be shaped to fit a recess or some obstruction on the wrest plank
(if my invention be used in a Piano) or a stud can be formed on the collet and be
made to fit a hole in the wrest plank to prevent it turning with the nut and to
ensure that the screw pin only has an end on motion.
I have mentioned that the wire or string can be secured in a transverse hole in
the head or outer end of the screw pin but other means may be adopted such for
instance when a "gut" is used, a knot can rest upon the head.

page_text: I THOMAS JAMES BRINSMEAD of the firm John Brinsmead and Sons 18 Wigmore
Street in the county of Middlesex, Pianoforte Manufacturers, do hereby declare the
nature of my said invention for "AN IMPROVEMENT CONNECTED WITH STRINGING
MUSICAL INSTRUMENTS," and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
The object of this invention is to secure the ends of wires or strings of stringed
musical instruments to the outer or more distant ends of screw pins by lodging
such wires or strings within the body or within a channel formed in the outer
portion of the whole or of a part of the length of the screw pin and in such
a manner that the wire or string is held by the screw pin at some part of the pin
beyond the screw nut by which the necessary tension can be put upon the wire or
string, the channel or groove in which the wire lodges being of sufficient depth
that the nut does not rub or bear against it. In connection with said recessed,
grooved, channelled or other shape of screw pin I use a collar provided on its inner
periphery and under surface with a-stud or feather which engages in a groove of
the pin and a corresponding hole or notch in the wrest plank to prevent the pin
turning round and twisting the wire or string when the nut is operated upon.
I have mentioned that the wire or string can be secured in a transverse hole in
the head or outer end of the screw pin but other means may be adopted such for
instance as twisting the end of the wire around a cross bar lodged on the outer
end of the screw pin or when a "gut" is used a knot can rest upon the head.
On the annexed sheet of drawings I show a few examples of my system of
attaching musical strings or wires at and from the outer ends of screw pins
(tuning pins).
In one example (Figures 1 and 2) the wire A is within a longitudinal groove
or channel B of the screw pin C the upper end of the wire being bent to go over
the end of the pin C into a short groove D formed in the pin C (see Figure 3) and
then again bent as at Figure 4 so that its extreme end can be lodged in a hole at E
to lock the wire firmly in position. The bent over wire is further secured and
prevented getting loose by the cap F (Figures 1 and 2) for which a ring or ferrule
may be substituted if desired as at Figure 5.
G is a washer or collar also shown detached at Figure 6 with a stud or feather
projecting from its under side and on its inner periphery. This stud fits in a
corresponding hole or notch in the wrest plank or bar L as in Figure 2 and whilst
preventing the pin C from turning round when the nut is operated upon to strain
the wire A for tuning purposes allows it to move with perfect freedom
longitudinally.
If the washer or collar G be square as at Figure 7 or of other equivalent shape
the stud H can be dispensed with.
Figures 8 and 9 are another example and are made in the form of a tube the
hole running through length of pin C and with the wire A bent over the outer
end of the pin C and fastened in the manner first explained.
Figure 10 shows the screw pin in form of a tube with wire A looped with a
wedge K introduced to fix it in position.
Figure 11 shows the wire A wrapped round a cross bar M to take the strain
through and along the hollow of the screw pin C.
At Figures 12 and 13 I show a flat sided screw pin C with a longitudinal groove
in which the wire A can lodge and be clear of the wrest plank or bar L whose holo
otherwise corresponds with the sectional configuration of the pin C. In this case
the washer or collar can be dispensed with as shown.

page_text: Figure 14 represents a screw pin C having an outside longitudinal groove for
early its length and then with a hole at an angle therefrom to lead the wire A to
the centre.
In several of the foregoing Figures I have shown a nut K which would require
the use of a spanner or key to turn it and such as would be necessary where great
strain of the wire is essential as in a piano but for musical instruments in which
gut strings are used ordinary thumb nuts as at Figure 15 will be sufficient and in
that case I prefer to carry the gut cord through the centre hole and put a knot at
its end to take the strain.
Other means of fastening the ends of wires after passing out of longitudinal
grooves or holes of screw pins could be used.
Figures 16 and 17 show a solid iron main frame of a piano with a projecting
wrest plank or bar L as part of the same casting to which my present system of
stringing is specially suitable. The projecting wrest plank or bar L as part of the
same casting of a main frame of a Piano, is part subject of prior Letters Patent
granted to me on the 21st day of May N° 2232 in the year 1881.
As shown, the projecting solid cast iron bar L has sufficient breadth to admit of
the tricord method of stringing being adopted.
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
[ claim is :-
1. Attaching wires or strings of musical instruments to the outer ends of screw
pins or at a point beyond or above the tension nuts said wires or strings
being within grooves or channels formed longitudinally in said screw pins
as described and substantially as shown in the drawings.
2. The plan of passing the strings or wires through a hole in the centre of
tuning pins or along a slot at the side or partially through a portion of each
such holes or slots being parallel with length of tuning pins as set forth.
3. The system of fixing steel wiro to tuning pins by bending it over quick
(angles) points inserting the end in a hole in tuning pin and then covering
said point by a metal ring or cap.
