SPECIFICATION forming part of Letters Patent No. 583,077', dated May 25, 1897.
Application filed April 24, 1896. Serial No. 588,854. (No inodel To all wton'z/ rit 7121/01/ con/007172,'
Be it known that I, GIUSEPPE OLIvERi, a citizen of the United States, residingat Washington, in the District of Columbia, have invented certain new and useful Improvements in IVind Instruments, of which the following is a specification.
My invention relates to tuning attach men ts for wind instruments; and it consists of an extensible core or rod with means for holding it centrally within the instrument, the same being adapted by changing the interior dimensions of the air-space to change the tone of the instrument either for the purpose of changing it from one key to another or for merely harmonizing the instrument with others.
In the accompanying drawings, Figure l represents a longitudinal section of the upper half, and Fig. 2 a similar section of the lower half, of a clarinet which is selected for the purpose of illustrating myinvention, such instrument having one form of my invention applied to it. Fig. 3 is a sectional detail view illustrating the form of attachment which is used in Figs. l and 2; and Fig. -t is an end view of the instrument, showing the support which is employed for the form of attachment shown in Figs. l, 2, and 8. Fig. 5 is a section on the line 5 5 of Fig. 2. Figs. G and 7 are respectively an axial section and an end view of the lower portion of an instrument having the attachment applied in slightlymodified form. Figs. 8 and 9 are axial sec` tions of the upper and lower parts of an instrument having applied thereto an attachment embodying my present invention and having means for adjusting the ends of the core or rod simultaneously and symmetrically. Figs. S and E)n are detail views, on an enlarged scale, showing, respectively, the detachable connection or joint in the core or filling-piece and the manner of supporting the lower end of the same and rendering it adjustable without removal from the instrument as well as readily removable in ease of necessity. Fig. lO is a fragmentary view of the upper and lower ends, showing a still further modiiication of the construction.
l represents a musical instrument which for purpose of illustration is shown to be in the form of a clarinet, jointed at 2, 3, and l. Mounted axially in the instrument is a core or rod 5, which has at its upper or lower or both ends extension -pieces (5 and 7. The 55 upper extension-piece G is carried adjacent to the mouthpiece, while the lower extensionpiece 7 is preferably located at the point where the bore of thc instrument begins to swell to form the bell. To render these pieces 6o 6 and 7 evenly extensible, they may be provided with telescoping sleeves 8 and 9 and axial screw-threaded pins l0 and ll, entering, respectively, into correspondinglythreaded sockets l2 and lf3, formed in the core or rod 65 as shown.
la represents a disk or spider mounted in the lower end of the instrument and adapted to receive a stud lf3, which projects from the lower extension-piece 7.
17 represents spring centering-arms carried at a point on the core or rod sufficiently above the supporting-spider le to center the core in the instrument and yet sufficiently low down in the instrument to avoid interference with 75 the sound-waves which determine the tone of the instrument.
From Figs. G and 7 it will beobserved that the disk or spider l-l may be formed integral with the lower extension-piece 7, and, if de- So sired, suitable means may be provided to enable it to be re1noved,with the core, from the instrument.
In Figs. S and 5) I have shown a shaft 2O ruiming through the core and having at its S5 upper end a right-handed thread 2l,wl1ich engages in the extension 6, and near its lower end a left-handed thread 22,working in a nut 23, which projects inwardly from the lower extension 7 through a slot 2l, formed in the 9o tube 5 of the core. The tube 5 of the core is extended and has a reduced neck 2G, which passes through brackets 27, having curved ends 2S, which pass down over and grip the lower edge of the bell 2i) of the instrument. 9 5 The shaft 2O carries a turning head 30 on its lower end, and by turning this head the extensions G and 7 are moved on the core 5 simultaneously and symmetrically in opposite directions. To provide for separating the ioo instrument, the shaft 2O is divided at the joint midway of the instrument, and one portion carries a socket 31 while the other has a squared pin 32, which tits in said socketand establishes turning connection between the parts of a shaft when the instrument is put together. The parts of the core are secured together by an ordinary screw-joint 33, and in order to prevent displacement of the shaft 2O its parts may be provided with the heads 23st, fitting in an enlargement in the cavity of the core.
As will be seen by reference to Fig. il, the brackets 27 are made separate and are adapted to be secured together by the nut 35, which screws on the extension 20 after the brackets have been passed over said extension. The parts are so constructed that when the brackets 27 are arranged symmetrically around the bell of the instrument they will form a rigid support for the whole attachment, but they may readily be slid around until they come together, at which time their hooks will be all on one side of the bell, and they will readily disengage and permit the whole attachment to be removed from the instrument.
According` to Fig. lO simultaneous movement of the extension-pieces G and 7 is effected through the medium of a lever 36, having its respective ends connected through straps 37, of rigid metal, to the respective extensions G and '7. lly applying the linger to the rocking lever 3S it may be moved in either direction and cause a corresponding simultaneous and uniform adjustment of the extensions b' and 7.
As will be observed, in all the torms of my invention the object is to change the cavity in the instrument, so as to alter its period of vibration and consequently its tone. The attachment is found in practice to be effective in changing the instrument from one key to another-ms, for instance, from lS-flat to A.. This may be done by moving the extensions or one of them to a su'fiicient degree, or the parts may be so adjusted that changes in the key may be effected by inserting and removing the entire attachment. On the other hand, by more gradual changes in the length of the attachment, it is very convenient to change the tone of the instrument in such slight degrees as to bring it into harmony with other instruments et' slightly-ditierent pitch.
While l have described and prefer to use the double extension, l desire it understood that my invention is not thus limited, as it is possible to obtain the desired results by extending at one end only or by any other method of changing the length of the core. l `urthermore, l desire it understood that my invent-ion is not limited in scope to an extensible core for the reason that, as previously explained, the desired ends may be obtained in changing from one key to another by inserting and removing the attachment.
llaving thus described my invention, the following is what l claim as new therein and desire to secure by Letters Patent:
l. A pitch-adjuster for clarin ets, Il tites, and other similar wind instruments, consisting of a rod and means whereby it may be held within the bore of the tube of the instrument.
ln combination with a tubular wind instrument; a core or filling-piece of smaller diameter than the internal diameter of thc instrument, and having means for supporting it within the instrument as and for the purpose explained.
3. ln combination with a musical instrument, the herein-described removable core or filling-piece mounted axially in the instrument in substantially the mannerand for the purposes set forth.
al.. In combination with a musical instrument, the herciit-described filling-piece or core, mounted axially within the instrument and provided with means for changing its dimensions, substantially as and for the purpose set forth.
ln combination lwith a musical instrument, the herein-described Iilling-piece er core, having means for mounting it axially within the instrument, and having an extensible end, substantially as and for the purpose set forth.
(j. ln combination with a musical instrument, the herein-described iilling-pieee or core provided with means for mounting it axially wit-hin the instrument, and having both its ends extensible substantially in the manner and lfor the purpose set forth.
