CLARINET SWAB V Filed Nova 20, 1947 122F517 Ur Patented Jan. 9, 1951 r CLARINET SWAB William I McKean, Elkhart, Ind., assignor to H. & A. Selmer, Inc., Elkhart, Ind.', a corporation of Indiana Application November 20, 1947, Serial No. 787,073
The present invention relates to apparatus for removing foreign matter from the interior surfaces of tubular objects and, more particularly to a swab for the cleaning of the bores of woodwind instruments.
During the use of a woodwind instrument.
moisture in the players breath passing through the instrument condenses within the bore of the instrument and must be removed to prevent interference with the operation of the instrument. The removal of the moisture from the interior of the instrument may be accomplished by dismantling the instrument into its component parts and swabbing the bore of the instrument with a swab or other suitable means.
Several types of swabs have been proposed for removing the moisture from woodwind instruments. The swabs generally employed are merely square or rectangular patches of cloth, chamois, or other suitable absorbent material attached to a cord by means of which the patch may be drawn through the instrument. The patches being larger than the bore of the instrument, are compressed into irregular shape within the bore of the instrument and rub against the interior surfaces of the bore. Due to the irregular shapeof the compressed patch, it has been impossible to effectively remove all of the moisture from the interior surface. In order to correct this ineficiency resulting from the irregular shape, it has been proposed that a conical follower in the form of a'brush or rubber cone be positioned on the cord so that the patch will fold over and around the follower in the bore and assume the regular shape of the follower. This method has not solved the problem of the moisture removal, since the apparatus may be employed with only one size of bore and an excessive amount of force must be exerted on the string to pull the patch and the tightly fitting follower through the instrument.
The present invention provides a swab for use in cleaning the bores of woodwind instruments or other tubular objects comprising a cord and a patch-of chamois, cloth or other flexible, nonscratching, water absorbent material attached to one end of the cord. It is preferred for use in the present invention that thepatch be of generally triangular shape and that the patch be slit inwardly from a trailing edge to form a plurality of tabs or wiping surfaces. patch is of triangular shape, it is desirable that the patch be attached to the cord at a point adjacent one of the apices of the triangle, and that the patch be slit inwardly from the edge opposite the apex. The patch may suitably be formed as an isosceles triangle with two identical sides 2 longer than the third slit side. The patch is slit inwardly from the short side of the triangle at a plurality of points for a distance of from one-quarter to one-half the length of the patch 5 to provide a plurality of tabs.
I have found that by the use of the patch of triangular shape, slit as above described, a more eficient swabbing action may be obtained. The patch, due to the triangular shape and the plul0 rality of tabs formed along the trailing edge,
assumes an almost perfect conical shape when pulled through the bore of the instrument by means of the cord. The improved cleaning efficiency obtained by the use of the swab of the present invention results from the conical shape moisture adhering thereto.
It is, therefore, an important object of the present invention to provide a clarinet swab comprising a cord and a patch attached thereto having its trailing edge slit to form a plurality of tabs, the tab construction permitting the patch to assume a conical shape presenting a plurality of wiping surfaces which contact the entire inner periphery of the instrument bore when pulled therethrough.
It is a further important object of the present 39 invention to provide a clarinet swab comprising a cord and a triangular patch attached thereto adjacent one of its apices and having the edge opposite the point of attachment slit to form a plurality of tabs, the slit construction permitting the patch to assume a substantially conical form Where the contacting the interior surfaces of the instrument to remove adherent moisture therefrom.
It is a further important object of the present invention to provide a clarinet swab comprising a cord and a triangular patch attached thereto adjacent one of the apices and having the edge opposite said one apex slit to form a plurality of tabs, said tab construction permitting the patch to present a uniform peripheral wiping surface contacting the inner surface of the clarinet when pulled therethrough.
Other and further important objects of this invention will be apparent from the disclosures in the specification and the accompanying draw ings.

As shown. on the drawings:
In Figure 1, reference numeral l refers generally to a clarinet swab of the present invention. The cord I I of the swab [0 may be formed of any suitable moisture-resistant material such as nylon. One end of the cord. H is looped as at I2;
the free end being secured. as. at It by a. plastic.
composition applied to the cord. As is further shown in Figure 1, the other endof the. cord. 1 l. is looped as at 14 (see Fig. 2) and is secured'at I 5.
As illustrated in Figure l, the looped end. I24 (see Fig. 2) of cord II is attached to a patch 18 by being passed through an apertur l6 fitted with a grommet I l. The patch. I8 is generally triangular in. shape. Aperture [6 isv located at the-.apexof the two. longer sides [9 and 200i the triangular patch |8',.and the edgel-lopposit the aperture i6 is provided with. a plurality of slits 22--to form a plurality of tabs 23. As may be seen in Figure 1,. the slits 22 extend inwardly toward the center. of. the patch for a distance of approximately one-quarter to-one-half the length of the patch l8.
As may be. seen in Figure 2, two patches may be employed, the two patches being of identical formand being joined only at their upper edges by a common grommet I] which passes through both patches. Alternatively, a patch 2 t may be provided by socutting thepatch blank that'two generally triangula patches, such as patch l8, arejoined at the apex and are merely folded over as shown in Figure 3 to form what is actually a pair of. joined patches similar in form to patch l8.
Toremove the. moisture and other foreign material from the interior of' a woodwind instrument, the instrument is first dismantled. intoits component parts and the parts are each sepa rately cleaned by the use of the swab of the present invention. As illustrated in Figure 4, the swabbing operation is very simple. The operator merely holds the clarinet part 25' in one hand and drops the doubled free'end. l2 of the cord ll through the bore of the clarinet and grasps the extending end in his other hand. The cord l I is then pulled. through the bore of the instrument, thus pullingthe patch [8 therethrough. As shown: in Figurev 4, the tabs on the trailing edge of the patches tend to flare outwardly into the general shape of a cone upon being pulled" through the boreof the instrument. The tabs thus form a generally circular wiping surface which contacts: the bore of the instrument as the swab is forcedtherethrough. The base of the cone formed by the patch is of greater diameter than: the bore of. the instrument, the patch being. compressed as it. is pulled thruthe bore. The compression of the; patch causes the tabs. in the outer periphery of the cone base tobear tightly against the bore surface.
Thus it may be seen that I have: provided; an improved clarinet swab by means of which moisture formed during the playing of the instrument, and other foreign matter may be removed from the bore of the instrument by merely pulling the swab therethrough. The swab of the present invention, by reason. of its slitted and tabbed construction assumes: a. conical: form when it is pulled through the bore of the instrument and presents a uniform peripheral surface which contacts the inner surface of the instrument to effectively remove the moisture and other foreign matter adhering thereto.
lit-will, of course, be. understood that various details of construction may be varied through a wide range without departing from the principles of this invention and it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended. claims.
