ARTHUR SCOTT BROOK, OF RUTHERFORD, NEW JERSEY.
ORGAN-PIPE.
Specification of Letters Patent.
Patented June 7, 1910.
Application filed March 26, 1909. Serial No. 485,878.
To all whom it may concern:
Be it known that I, ARTHUR SCOTT BRooK, a subject of the King of Great Britain, and residing at Rutherford, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Organ-Pipes, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.
This invention relates to organ pipes; and the object thereof is to provide an organ pipe which will produce musical tones in which the harmonics are made prominent, whereby a quality of tone possessing greater beauty than that produced by organ pipes made in the usual manner is produced; a further object being to provide an or an pipe which will produce a tone differing from that produced by any organ pipe at present known, whereby its combination with other pipes in an organ will make a greater range or variety of tones and tonal combinations available; and with these and other objects in view, the invention comprises an organ pipe open at both ends and having its blow aperture located between the ends of the pipe and supplied with air through an attachment communicating with said aperture and with the wind chest in such manner that instead of having a single vibrating column of air as in ordinary forms of organ pipes, it will have two, one above and one below said aperture which will vibrate simultaneously to produce the note of the pipe.
The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a sectional side view of an organ pipe involving one form of my invention, Fig. 2 a view looking in the direction of the arrow 00 of Fig. 1, Fig. 3 a view similar to Fig. 1, but showing a modification, Fig. 4 a view similar to Fig. 2, of the construction shown in Fig. 3, Fig. 5 a sectional. view on the line 5-5 of Fig. 4, and ;Fig. 6 a view similar to Fig. 1, but showing another modification.
It is well known, that in practice, organ pipes are made, in general, of two materials wood and metal, and in Figs. 1 and 2 of the accompanying drawing I have shown my improvement applied to what is known as a labial pipe.
The pipe is indicated at a, and this pipe is open at both ends and is provided in one side thereof and at any desired point between the ends with the usual transverse blow aperture a which is rectangular in form and the upper edge or lip of the aperture a is beveled to form an edge, the side of the pipe on which the said aperture is located being beveled as shown at a for this purpose, and the lower lip of the aperture a is similarly beveled to form an edge though in less degree than the upper edge or lip as shown at a.
The lower end portion of the pipe is provided with the usual attachment 6 by means of which connection with the wind chest of the organ is made, and this attachment consists of a cap, conduit or case 6 provided with a depending tubular member Z2 which is tapered at its lower end as shown at (1* whereby it may be connected with the wind chest of the organ in the usual manner, said wind chest being not shown.
The cap 6 is preferably rectangular in cross section, and the parts 6 and 6 form a continuous wind-way or passage 6 which forms a communication between the wind chest of the organ and the aperture of of the pipe, and the upper end of this wind-way or passage is reduced in size and tapered down to a very narrow outlet, preferably the same form as the aperture of and of a width approximately equal to that of said aperture, said outlet being shown at b.
In the operation of this pipe, the air passes under pressure from the wind chest upward through the wind-way I) and out through the slit or outlet b and strikes on the lip a of the aperture a of the pipe and sets into vibration the air inclosed in the pipe and produces musical tones. The musical tones thus produced are the sum of several tones one of which is produced by the vibration of that part of the column of air in the pipe above the aperture a another being produced by the vibration of that part of the column of air in the pipe below said aperture of, and at the same time a number of harmonics are produced.
The aperture a may be located at any desired point between the ends of the pipe, and it will be understood that the location of said aperture will give difi'erent resulting tones, the character of the tones depending LII on the different heights of the different columns of air in the pipe.
In Figs. 3, 4 and 5 of the drawing I have shown a labial pipe embodying my invention made of metal, and it will be seen that this form of construction is essentially the same as that shown in Figs. 1 and 2. The pipe is circular in cross section in this form of construction however, and the aperture a is located in one side of the pipe and at any predetermined distance between the ends thereof, and in this form of construction the aperture a is provided with the usual side guards c. In this form of construction the attachment 6 which forms the wind-way b is also made of metal, and consists of an upper end portion Z2 and a lower end portion 5 and the upper end portion is semicircular in cross section to correspond with the form of the pipe a in cross section and is connected with said pipe in any desired manner, and the lower end portion is set inwardly and enlarged as shown at b and the end thereof tapered as shown at b to facilitate its connection with the wind chest of the organ, and the operation with this form of construction will be the same as with that shown in Figs. 1 and 2.
The form of construction shown in Fig. 6 involves the application of my invention to what is known as a reed pipe, in this form of construction the pipe a is provided in one side thereof with an aperture or opening 6, and this aperture or opening is or may be located at any desired point between the ends of the pipe. In this form of construction the attachment 1) is also employed, and consists of an upper part c and lower part 7' connected therewith. The upper part c is tubular in cross section and is connected with the pipe a and incloses the aperture 0, and said part is tapered downwardly and communicates with a tone producing part f comprising the usual members, namely the tube 6 the reed 0*, the block 6 the tongue 6, the wedge 6 the tuning rod e and the boot a. The lower end of the boot 6 is contracted at f to facilitate its connection with the wind chest of the organ in the usual manner. lVith this form of construction, the air inclosed in the pipe at is set into vibration by the vibrating air in the tube a and qualifies the tones produced in a manner similar to that described in connection with the other forms of construction shown in Figs. 1 to 5 inclusive.
From the foregoing, it will be seen, that in all the forms of construction the main pipe member is the same and is open throughout or at both ends, and this as hereinbefore stated, constitutes the chief feature of my invention, the other part or parts being substantially the same according to the style of the pipe or the use thereof, and
consisting in all cases of an attachment connected with the pipe and adapted to be connected with the wind chest of the organ.
By means of the forms of construction for organ pipes herein set forth, I provide an organ pipe which will have greater beauty of tone than pipes of ordinary construction, because of the fact that the tone produced therein is the sum of a greater number of harmonics with the fundamental tone than is attained in pipes of ordinary construction, and in this way I also provide a tone having a quality ditfering from that of pipes made according to known forms of construction, and thereby increase the range of tonal combinations available in an organ.
It will be understood, of course, that while I have specified that the pipes illustrated in connection with this specification are made of wood and metal, it will be obvious that my invention may be used in pipes of any material suitable for the purpose, and I wish to point out particularly that my invention does not specify any particular location of the aperture a of the labial pipes or the aperture 6 of the reed pipes with respect to the extreme ends of the pipe, and my invention is not limited to the exact details of construction herein shown, and many changes therein and modifications thereof may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is
1. An organ pipe comprising a main tube open throughout its length and the ends of which are unobstructed, said pipe being provided in one side thereof with a blow aperture adapted to be placed in communication with the wind chest of an organ.
2. An organ pipe comprising a main tube open throughout its length and the ends of which are unobstructed, said pipe being provided between the ends thereof and in one side thereof with a blow aperture, and means for placing said aperture in communication with the wind chest of an organ.
3. An organ pipe, comprising a main tube open and unobstructed throughout its length, said pipe being provided in one side thereof with a blow aperture and a tube adapted to connect said aperture with the wind chest of an organ.
In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing witnesses this 18th day of March 1909.
