403,822. Guitars and c. RICHARDSON, E., 48, Portland Road, Nottingham.
Jan. 31, 1933, No. 2971. Drawings to Specification. [Class 88 (ii).] A
guitar having a tone-chamber with a single sound-hole is provided with
two
sets of strings which are arranged over separate fretted
fingerboards and necks connected to a single head and yield different
effects. One set is played as a Hawaiian guitar by means of a steel,
the strings being set at a greater height above the finger board to
prevent them being pressed into contact therewith, by making the
corresponding nut and bridge of increased height. The bridges of the
two sets may be made integral. Either set may be tuned to function as
a banjo.

PATENT SPECIFICA and TION I, EDWARD Ri CHARDSON, a British' Subject,
of 48, Portland Road, Nottingham, do hereby declare the nature of this
invention to be as follows:i This invention comprises improvements in
stringed
musical instruments and, has particular, although not
exclusive, reference to guitars; the main object of the invention
being so to construct an instruj 1 ment of this type as to enable one
and' the same instrument to be utilisea for obtaining different types
of music the production of which has hitherto necessitated the
employment
of a plurality of instruments; thereby considerably
increasing the utility and enhancing the value of the instrument.
Broadly, the present invention comprises a
guitar) embodying in a self-contained manner
sets
or
groups of strings, said sets
selectively operative at Will and each set
different class of music or different musical
stringed instrument (e g
a plurality of separated
being individually and
functioning to produce a
effects.
More particularly the invention comprises a guitar which embodies two
sets of strings so arranged or incorporated as to constitute in one
instrument two different types of guitar, e g a Spanish and Hawaiian
guitar.
In one method of carrying out the invention a guitar is provided with
a body of the customary design, but instead of said body having a
single finger-board extending therefrom same is provided with two
finger-boards laterally spaced apart and projecting parallel or
substantially parallel with each other Each 4 O finger-board is
provided with a set or group of strings, say for example six stringsi
each set; of strings being connected in the customary manner at the
head of the instrument, passed over a nut 403,822 at said head so as
to maintain the strings 45 raised over the finger-board, passed over a
bridge on the instrument body and con' nected to any suitable type of
tail piece at the lower part of said body The -nut and bridge pieces
appertaining to the 50 one set of strings are comparatively low so as
to-produce a guitar of the Spanish or Plectrum type in which the
strings are Ipressed down on to during the playing of same, The nut
and bridge pieces over 55 which the second set of strings extend are
comparatively high so as to maintain the stretched strings raised
above their fingerboard and enable the strings to be pressed by steel
or similar fret without moving 60 same into contact with the
finger-board thereby producing on said second set of strings musical
effects as produced on a Hawaiian guitar.
The head of the instrument, i e the 65 portion at the outer end of the
fingerboards advantageously constitutes a, single piece or member
conlnecting together said finger-boards, the strings appertaining'to
the two sets being adjust 70 ably connected to said head in the
customary manner The finger-boards are also provided with transverse
marks at intervals in their length to denote semitones 75 From the
above it will be appreciated that in one and the same instrument two
guitars are provided which can be operated upon selectively as
required, thereby obviating the necessity of em 80 ploying and
transporting two separate instruments for producing the two classes of
music.

I, EDWARD RICH:EARDSON, -a British is to be performed, to be
particularly 8 Subject, of 48, Portland Road, Notting described and
ascertained in and by the ham, do hereby declare -the nature of -this
following statement ' 90 invention and in what manner the same This
invention comprises improvements lPries 11-l P2 Application Date:

PROVISIONAL SPECIFICATION.
Improvements in Stringed Musical Instruments. in stringed musical
instruments particularly guitars wherein different musical effects may
be obtained from different groups of strings.
According to the present invention a stringed musical instrument (e g
a guitar) comprises a body with tone chamber, a plurality of
laterally-spaced necks with finger-boards extending from said 1 o body
and a separate set of strings extending over each neck, and wherein
the necks terminate in one common head and all of the strings
appertairing to the separate sets are connected to said head.
Advantageously two separately operable sets of strings are provided,
the said two sets of strings being raised to different heights clie
their respective fingerboards so Yat when playing the instrument the
strings of one set or group are adapted to be pressed on to the
associated finger-board while the strings of the second set or group
which are raised to a higher level above the finger-board are 2,
adapted to be played by movement of a steel fret over same without
pressing the strings into contact with the finger-board.
By this means musical effects obtained from one set or group of
strings are different from those obtained when playing on the other
set.
Although a dual stringed musical instrument such as a guitar with tone
chamber has previously been proposed having o 36 two necks, provided
with finger boards, extending from the same body and a separate set-of
separately operable strings extending over each neck, the two necks
are not; as is the case in the present invention connected to a common
head; neither has it been suggested in such instrument to locate the
two sets of strings at different heights above their respective necks
Also in a previously proposed instrument which combines a harp with a
guitar, two sets of strings extend from a common tone chamber with
single sound hole, but in such instrument there is only one finger
board over which one set of strings extend, the other set extending to
a frame projecting laterally from the top of said board.
Additionally in a guitar or the like it has been proposed to raise
either one or 5, two strings of a set of six strings above the level
of the remainder and carry same over an extension of the instrument
bridge; bbut in such arrangement there are not separate sets of
strings extending o over laterally spaced necks connected to a common
head as in the present invention.
For the purpose of more fully describing the nature of this invention
reference will now be made to the accompanying drawings, whereinFigure
1 illustrates in front elevation an instrument according to the
present invention.
Figure 2 illustrates the same instrument in side elevation.
In one method of carrying out the invention a guitar is provided with
a body 1 of the customary design, but instead of said body having a
single finger-board extending therefrom same is provided 75 with two
finger-boards 2 laterally spaced apart and projecting parallel or
substantially parallel with each other Each finger-board 2 is provided
with a complete set or group of strings 3 preferably 80 six strings,
each set of strings being connected in the customary manner at the
head 4 of the instrument, passed over a nut at said head so as to
maintain the strings raised over the finger-board, 85 passed over a
bridge on the instrument body 1 and connected to any suitable type of
hinged tail piece 5 at the lower part of said body The nut 6 and
bridge 7 appertaining to one set of strings are 90 comparatively low
so as to produce a guitar of the Spanish or Plectrum type in which the
strings are pressed down on to the finger-board during playing The nut
Qa and bridge 7 a over which the 95 second set of strings extend are
comparatively high so as to maintain the stretched strings raised
above their finger-board 2 and enable the strings to be pressed by a
steel or similar fret without bringing i 00 same into contact with the
finger-board, thereby producing on said second set of strings musical
effects as produced on a Hawaiian guitar Either set of strings can,
however, be tuned to function as a i 05 Banjo.
The head 4 ok the instrument, i e. the portion at the outer end of the
fingerboards
2,
constitutes a member connecting together said
finger-boards and the two lo neck portions 8 on which said boards are
mounted, the strings appertaining to the two sets being adjustably
connected to tuning elements 9 provided in said head in the customary
manner The finger 115 boards 2 are also provided with transverse marks
or raised lines 10 at intervals in their length to denote semi-tones.
Having now particularly described and ascertained the nature of my
said inven 120 tion and in what manner the same is to be performed, I
declare that what I
