The harp l0 may be made with from three to
This invention relates to improvements in
harps.
‘
An important object of this invention is to
provide a harp capable of producing chromatic
5' tones and on which music written in major or
minor scale can be played without dif?culty.
Another object of the invention is to provide
a harp which is simple in operation so that one
skilled in the piano-or organ can readily acquire
lol pro?ciency in playing this harp.
A further object of the invention is to provide
improved sounding means, tone control, and key
indicating means to simplify the playing of music
written in major or minor scale.
Additional objects and advantages of the in
vention will hereinafter become more readily ap
parent from the following speci?cation of which
the drawing forms a part, and wherein:
Figure 1 is a side elevational view of the inven
ro tion,
‘Figure 2 is a vertical sectional view on the
line 2—2 of Figure 1, and
Figure 3 is a horizontal sectional View on the
line 3-3 of Figure 1.
Referring more particularly to the drawing
wherein like reference characters indicate like
or corresponding parts throughout, l0 designates
generally the harp comprising the frame portion
composed of the pedestal ||, back l2, neck l3,
so and pillar l4.
‘
In the conventional harp the upper or front
part |5 of the back l2 forms the sound board. As
seen in Figures 2 and 3 the pedestal ||, pillar
l4, and back l2 are hollow to- form additional
resonant chambers. Harp H] is also provided
with a vertically disposed sound box IE having
its open side abutting the inner side of pillar M
as seen in Figure 3, and extending between neck
l3 and sound board |5 of the back l2 on the
40 right side of harp I0, looking in the direction
indicated by the arrows 2—2 in Figure 1.
Secured to the middle of the sound board por
tion I5 and extending one-half the length there
of is an angular member |'| having its upwardly
45 extending side |8 provided with uniformly ar
ranged apertures l9 comprising openings termi
nating in slots. The openings are adapted to
receive the knotted ends of the harp strings 20
which are held therein by the knotted ends en
.30 gaging the slotted portions. Strings 20 are
stretched across the open part 2| of harp l0
and across the left side of box Hi and are at
tached to- the wrest pins 22 which are mounted
in two rows on the neck |3 and by means of
or» which strings 20 are tuned.
eight octaves. It may be manufactured with as
many as eighty-eight strings, but preferably is
composed of ‘sixty-two strings, as illustrated
comprising slightly more than ?ve octaves.
Extending the length of opening 2| and at
tached {to the underside of neck l3 and to the
left side- of box I6, is the strip 23 which is marked
as indicated at 24 to correspond to the keyboard
of a piano._
A string 2| extends over each of 10
the key marks 24 and is tuned to correspond to
the key over which it is placed so that the mu
sician can more readily pick the strings with his
?ngers using strip 231as a guide, in order to make
possible ‘the ‘playing of music written in major 15
and minor scale. A damper head 25 is provided
which is pivotally mounted in car 26 on sound
board l5 and in an opening in pillar M to sup
port it transversely of the springs 20von the op
posite side'to box 15. Damper head 25 is pro
vided with an angular lug 21 as best seen in
Figure 2 which is connected to the vertically
disposed rod 28 which extends down into pedes
tal |.|. Pedestal H is provided with an inter
nally disposed depending partition 29 on which 25
is pivotally mounted a lever 30 having one end
connected to rod 28‘ and the opposite end con
nected to ‘pedal lever 3| which is pivoted at its
end 32 to the partition 29. Pedal 3| has its op
posite end projecting through a vertical slot 33 '
in the left side of pedestal | |, and mounted there
on is a roller 34 forming a foot pedal.
A leaf
type spring 35 has one end engaging pedal 3|
and the opposite end resting on the bottom of
pedestal II to hold pedal 3| in an elevated posi
tion as illustrated. When in this position rod
28 is in its lowered position holding damper head
25 out of engagement with strings 20. When
pedal 34 is pressed down lever 30 is rocked rais
ing rod» 28 and swinging‘damper head 25 into
engagement with strings 20. Damper head 25
r.

has a felt strip 36 secured to its inner side to
engage strings 20.
Mounted on the underside of pedestal H are
the rubber pads 31 on which harp I0 is partially
supported and which prevent the harp from slid
ing while being played. Mounted under the hori
zontal portion of back I2 is a'roller 38 which
cooperates with pads 31 to support the harp l0,
and on which harp I0 may be rolled by tilting it 50
to raise pads 31.
Attached to pillar l4, as seen in Figure 3, is a
bracket 39 to which is removably attached arm
40 which supports a music rack 4|.
Sound box I6 is provided with openings 42; 55

sound board [5 with openings 43; and pedestal
H with the elongated openings 44 by which the
tones produced by strings 20 are released.
The sound box i6 which connects with pillar l4
and sound board 15 produces the chromatic tones
necessary for music played in the major or minor
scale.
The harp I0 is played by picking the base
strings, which are the long strings and which ex
10 tend along the side of the box 16 with the left
hand only, while the ‘_‘G” string below middle
and the strings above it may be played with
therewith to produce chromatic tones, and a bar
arranged transversely of the strings and marked
adjacent each string to correspond with a piano
keyboard to permit said strings to be played by
chords corresponding to a piano.
3. In a harp, a sounding box adapted to be dis
posed along one side of certain of the strings,
said sounding box comprising spaced panels con
nected along one side, the opposite side, top and
bottom being open, said open side, top and bottom 10

neck and sound board, respectively, of the harp
both hands but preferably with the right hand on v ‘and to communicate with said parts in produc
the right side of the harp, or the side to which ing deep melodious tones, and the panel of said
box I 6 is secured.
Damper head 25 is operated by
the foot engaging pedal 34 to control the tone
vibrations of strings 2!), the roller 34 preventing
the harp from being pushed away from the artist
when the roller is depressed. The harp l0 due
to its construction will stay in tune inde?nitely,
and is adapted to be tuned to correspond to a
piano as heretofore explained. The artist pref
erably sits or stands behind the harp with the
right shoulder resting against the back l2 so that
the head is to the left of the harp and conven
iently positioned for watching the strip or guide
23, while playing. In this position, the left hand
is free to conveniently pickthe base, or long
strings, on the left side of the harp l0, while the
treble strings, or short strings, can be picked with
the right hand on the opposite or right side of
the harp.
The left hand will be usually disposed

.4. A harp provided with a pedestal, pillar, back
and neck, said pillar, back and neck forming an
opening, strings stretched vertically across said 20
opening and secured to the back and neck, and a
sounding box disposed between said back and
neck, and on one side of certain of said strings,
with one of its sides in engagement with said
pillar, said sounding box being provided with a 25
hollow resonant chamber and having a plurality
of openings opening outwardly thereof.
5. A harp having a hollow pedestal, pillar and
back forming resonant chambers, said back and
pedestal being provided with sound releasing
openings, and a sounding box having a vertically
disposed resonant chamber, said sounding box
beneath strip 25, but if necessary, where the treble
being positioned in the harp opening and con
strings alone are being played, the left hand may
be used to pick these strings above strip 25.
