Claim 1 of letters patent No, 81,241, granted February 23d 1869,
to Riley Burden, as inventor, for 17 years from August 24, 1868,
for an "improvement in reed organs," namely,
"The arrangement, in a reed musical instrument, of the reed
board A, having the diapason set
a and its octave set
b and the additional set L, extending from about at tenor
F upward through the scale, substantially as and to the effect set
forth,"
defined and construed.
A reed board with two sets of reeds and a third partial set was
made and put into an organ by one Dayton prior to the invention of
Burden, and, such organ being put in evidence, it was held that the
alleged infringing organs contained nothing which, so far as said
claim 1 was concerned, was not found in such prior organ.
As to claim 2, namely,
"The reed board A, and foundation board G, constructed with the
contracted valve openings D F F, and the reeds arranged in relation
thereto, all in the manner described,"
it was held that, in view of the state of the art, there was no
invention in making the length and size of the valve opening
greater or less in a reed board of a given width, or where the reed
board was made wider or narrower, or had more or less sets of reeds
in it, either full or partial, and that the vibrating ends of the
lowest and longest reeds in such prior organ were as near together
as they were in the reed boards of the alleged infringing organs.
On these views, a decree was entered in favor of the
defendants.
Bill in equity for infringement of a patent for reed celeste
organs
MR. JUSTICE BLATCHFORD delivered the opinion of the Court.
This is a suit in equity brought for the infringement of letters
patent No. 87,241, granted February 23, 1869, to Riley Burdett, the
plaintiff, for 17 years from August 24, 1868, for an "improvement
in reed organs." The specification of the patent is in these
words:

"Figure 1 is a perspective view of one of my reed celeste
organs. Figure 2 is a diagram plan, showing the relative
arrangement of the needs. Figure 3 is a vertical transverse section
of my reed board, etc. This invention consists first in the
arrangement of the reed board; second in a method of tuning by
which a peculiar quality of tone is produced and by which the power
of the instrument is greatly increased without an increased
resistance in the action and without an increase of power being
necessary to operate the bellows. The advantages gained by my
peculiar arrangement are a greatly in creased power and variety of
tone. This is effected by the use of an additional set of reeds,
commencing at tenor F or thereabouts and running upward through the
scale of the instrument and tuning the same in the peculiar manner
hereinafter described. No other reed
Page 109 U. S. 635
musical instrument containing the same number of reeds, so far
as I know, has ever possessed so great a variety or pleasing
quality of tone, while simplicity of construction, compactness of
form, and ease of operation are other exellencies of this
arrangement not found in others. I will now describe particularly
the construction of that part of my instrument which forms the
subject of this patent. The case, bellows, pedals, etc., may be, in
general construction and arrangement, like those in common use, and
therefore no special description is required. The foundation of the
reed board is also constructed in the usual manner, but the reed
board proper, in itself, differs from the ordinary reed board in
the following particulars,
viz., the main board A contains
two sets of reeds running through the entire scale, the back set of
which is marked
a and is tuned as a unison or diapason,
while the front or octave set, marked
b, is tuned an
octave above the diapason. In the arrangement of these reeds, it
will be seen that the lowest and longest reeds in the diapason and
the octave sets are placed with their vibrating ends as near
together as they can be, with room only for the tracker pin which
communicates the motion of the key to the valve beneath the reeds.
But as the reeds continually shorten as they advance upward in the
scale, there is necessarily a vacant space left between the
diapason set
a and the octave set
b which
constantly enlarges itself, and has heretofore been regarded as
useless. Within this space, commencing on tenor F and running
upward through the scale, I have introduced a third set of reeds,
L, which forms the distinguishing feature of this instrument. These
are placed in the reed board over the octave set
b, and
run obliquely to the foundation board G, as shown in Figure 3, the
vibrating ends resting on the same base as the other sets of reeds,
a and
b. These reeds are of the same size as the
corresponding ones in the diapason
a, and are tuned either
a trifle above or below the diapason, but only sufficiently so to
produce a slightly waving and undulating quality or effect, without
producing any discord. A few trials will enable any tuner of reed
instruments to tune these reeds so as to realize the best effect.
This method of tuning will, when this set of reeds, which I have
named the Harmonic Celeste, is drawn and used in connection with
the diapason, produce a most wonderfully pleasing and captivating
effect, while the power and beauty of both sets of reeds are
greatly augmented and enriched in a
Page 109 U. S. 636
manner which cannot be realized without being heard. Figure 2
shows a top view of the reed board proper, wherein the location of
the reeds is shown with reference to the divergence of the reeds of
the diapason set
a and the octave set
b, and also
the space afforded for the introduction of the third set, L. Figure
3 exhibits a transverse section of my reed and foundation board,
showing the arrangement of my reeds and the valve connections. In
this figure, A is the reed board, G is the foundation board, D is
the valve opening, E is the valve, and FF are the throats over
which the reeds are located and placed. The valve E is retained in
its proper place by the pins
e e and spring H, and is
operated by the tracker pin I, which rests upon its upper surface
and passes upwards through the reed board to the under surface of
the key N. The swell boards J and K and stop dampers B and M are
raised whenever desired by the knee stop C, Figure 1, or by a hand
draw stop, or by some other convenient device. Another important
advantage arising from the introduction of the Harmonic Celeste is
that a greater power and variety are attained than can be by the
use of any of the octave coupling arrangements now in use. These,
while they augment the power, by drawing down octaves to the keys
actually played, are objectionable inasmuch as they offer more than
double the resistance to the key, and are thus often exceedingly
undesirable. In my instrument no such objection can ever arise, as
the pressure upon the keys is always the same, whether one or all
the sets of reeds are used. This is of prime importance to the
performer, as the required exertion becomes involuntary, and not a
matter of calculation, and thus the mind is not distracted from the
proper feeling and expression of the music performed."
The claims of the patent are as follows:
"1. The arrangement, in a reed musical instrument, of the reed
board A, having the diapason set
a and its octave set
b and the additional set L extending from about at tenor F
upward through the scale, substantially as and to the effect set
forth."
"2. The reed board A and foundation board G, constructed with
the contracted valve openings D, FF, and the reeds arranged in
relation thereto, all in the manner described."
"3. he diapason
a and its octave or principal
b, arranged over the same valve opening, as described, so
that the octave unison may be produced, when desired, without the
use of coupler and without any additional pressure upon the
keys."
"4. In connection with the reed board A,
Page 109 U. S. 637
having the sets
a, b, and L, as described, the
independent dampers B and M, as set forth."
The circuit court made an interlocutory decree declaring the
patent to be valid so far as claims 1 and 2 are concerned; that
those two claims had been infringed; that the plaintiff was not the
original and first inventor of what is set forth in claim 4 and did
not before the commencement of this suit file a disclaimer of what
is claimed in claim 4, and had not unreasonably neglected to file
such disclaimer, and had presented evidence of his having filed
such disclaimer; that no evidence had been offered to show any
infringement of claim 3, and that the plaintiff was entitled to
recover profits and damages because of such infringement. A
reference to a master to ascertain the same was ordered and a
perpetual injunction was awarded as to claims 1 and 2. On the
report of the master, a final decree was made for the plaintiff for
$161,011.79, without costs to either party. The decisions of the
circuit court in the case are reported in 15 Blatchford C.C. 349;
16 Blatchford C.C. 105, and 19 Blatchford C.C. 1. The defendants
have appealed.
An examination of the text of the specification shows that the
inventor purposed to cover by his patent two things: (1) a new
arrangement of the reed board; (2) a new method of tuning. In the
application for the patent, claim 1 read as it does now, while
claims 2, 3, and 4 had specific reference to the method of tuning
described. The Patent Office rejected all the claims. The plaintiff
then amended two of the claims relative to tuning, still retaining
the tuning feature in them, and added the claims which are now
claims 2, 3, and 4. The office then rejected all seven of the
claims. On appeal to the examiners in chief, the decision rejecting
the three tuning claims was affirmed and that rejecting the other
four claims was reversed, and the patent was issued accordingly.
There is nothing in claims 1 and 2 as granted which has any
reference to any new method of tuning, unless it is to be intended,
in accordance with the description, that the partial set is to be
capable of being tuned a trifle above or below the diapason set.
Except perhaps to that extent, all there is in the descriptive part
of
Page 109 U. S. 638
the specification in relation to a new method of tuning may be
dismissed from consideration, as it was introduced to lay a
foundation for the original claims 2, 3, and 4, in reference to
such new method of tuning. Claims 1 and 2, as they stand, relate
only to the arrangement of the reed board and the sets of reeds in
conjunction with the foundation board and the valve openings and
the valves.
The specification shows that the inventor takes a reed board
having two sets of reeds running through the entire scale, a
diapason set and an octave or principal set, and makes no change in
the foundation board or in the case, bellows, pedal, etc. The reed
board with the two sets was old. In its structure, as shown in
Figure 2 of the drawings and as described in the specification, the
lowest and longest reeds in the two sets are placed so near
together as to leave between them room only for the tracker pin
which communicates motion from the key to the valve; but as the
reeds shorten continually as the scale proceeds upward, there is a
vacant space between the ends of the reeds in the two sets, which
space continually grows wider. Within that space the inventor
introduces a third set of reeds, commencing at or about tenor F and
running upward through the scale. He places this third set over the
octave set, and the reeds run downwardly in a direction oblique to
the foundation board, and their vibrating ends, which are their
lower ends, rest on the same base as that of the other two sets of
reeds. They are of the same size as the corresponding reeds in the
diapason set. The point of advantage in bringing down the vibrating
ends of the reeds in the third set, so that they shall rest on the
same base with the vibrating ends of the reeds in the other two
sets, is shown by the evidence to be the same point of advantage
which is set forth in the specification of the prior patent granted
to the plaintiff on the ninth of January, 1866. In that, the
invention is stated to be to so make the reed board that the three
or four sets of reeds in it shall be acted upon instantly and
simultaneously by the rush of air upon the opening of the valve,
and it is set forth that that result is effected by placing two
sets of reeds on the same horizontal plane, and placing the other
sets on an inclined plane,
Page 109 U. S. 639
each with its base on the same level as the first and second
sets, thus making the head of each reed equidistant from the valve
and making each produce instantaneous concerted sound.
There was introduced in evidence a reed organ, known as exhibit
No. 21, containing reed board with two sets of reeds and a third
partial set, alleged to have been made by one Dayton in 1866, prior
to the plaintiff's invention. There was much testimony on the
question as to whether the reed board and reeds in this organ were
made prior to the plaintiff's invention, in the shape in which they
appeared when put in evidence. The circuit court decided that
question in the affirmative, but nevertheless it held that the
arrangement of reed board and reeds found in No. 21 did not embrace
the entire arrangement specified and claimed in claim 1 of the
patent because, although it had a reed board no wider than was
necessary for two full sets of reeds, and had an additional partial
set of reeds put in on an incline, and although the reeds in that
set may have been tuned flat in relation to the diapason set, yet
such reeds did not rest on the same base as that of the other two
sets of reeds. We concur with the circuit court in its conclusion
as to the genuineness and the date of No. 21, but are of opinion
that there is nothing found in the alleged infringing organs which,
so far as claim 1 of the plaintiff's patent is concerned, is not
found in No. 21. The vibrating reeds in the partial set in the
alleged infringing organs do not rest on the same base as that of
the other two sets of reeds, and occupy a position in that respect
no different, in reference to any requirement of the plaintiff's
patent, from that occupied by the vibrating ends of the partial set
in No. 21. In all other respects in which the alleged infringing
reed board and reeds embrace what is covered by claim 1 of the
plaintiff's patent, what they contain is found in No. 21.
The material point in claim 2 is the contraction of the valve
openings. The idea is that the valve openings and passages for the
two complete sets of reeds and the intermediate partial set are
contracted or condensed within the same space which was usually
occupied by the valve openings and passages for only two complete
sets of reeds in an instrument of the usual
Page 109 U. S. 640
prior construction, and that therefore no more force is required
to be applied to the keys to open the valves than where only two
full sets of reeds are used. The circuit court was of opinion that
the valve openings in No. 21 were not the contracted valve openings
of the plaintiff's patent, because they were as large as the valve
openings in a reed board having three full sets of reeds, and that
the lowest and longest reeds in No. 21 did not, as in the
plaintiff's arrangement, have their vibrating ends as near together
as they could be, with room between them only for the tracker pin.
Our conclusion is that the absolute length and size of the valve
opening was a matter of judgment in view of the state of the art
shown, and that there was no invention in making its length and
size greater or less in a reed board of a given width, or where the
reed board was made wider or narrower, or had more or less sets of
reeds in it, either full or partial. The dimensions of the valve
opening and of the valve are regulated by the judgment of the
manufacturer as to the quantity of air necessary and the resistance
to be overcome in working the valve and the inconvenience of the
leakage of air. We are also satisfied that the vibrating ends of
the lowest and longest reeds in No. 21 were as near together as
they are in the reed boards of alleged infringing organs.
It results from these considerations that
The decree of the circuit court must be reversed and the
case be remanded to that court with direction to dismiss the
bill.
