8' Claims. 1,

This invention relates to musical instruments,

and more particularly to wire brushes, sometimesreferred to as jazz drum switches.

The wire brush is used with the drum or cymbal to obtain patter and swish-like sound eifects. It comprises a tubular handle having at one end a plurality of thin gauge steel wires which spread out in the manner of a fan and are fastened to a clip or lug seated within and slidable along the length of the handle. For adjusting the spread of the wires, there is provided a metal rod which is fixedly connected at one end to the lug in the interior of the handle. The other end. of

the. rod terminates in a loop or a ball located outside the handle to enable the rod. to be easily grasped by the hand and moved along the longitudinal axis of the handle, thereby permitting; adjustment of the effective length and the spread of the wires.

One difiiculty experienced with known types of wire brushes is that the length of the rod which protrudes from the handle changes during use for different adjustments of the wires, thus interfering with the balance or feel of the instrument in the hand of the user.

Another difiiculty' is caused by undesired changes in adjustment of the wires during usage, due to inadvertent movement of the rod.

The present invention overcomes the foregoing difficulties.

According to the invention, means are provided for varying the relative length of the rod with respect to the tubular handle by desired amounts.

In accordance with oneembodiment of the invention, there is provided a spiral spring whichis wound around the loop" and whose turns near one end are more widely spaced apart than the turns near the other end. Putting it in other words, the pitch of the spiral spring is difierent along different portions of its length. The spring thus acts like a worm. This spring can be manipulated by the fingers of the musician to enable the rod to enter into the handle a greater or lesser distance, thus providing an adjustment of, the spread of the wires.

According to another embodiment of the invention, the handle itself is adjustable inlength.

By way of example only andnot by way. of

limitation, this adjustment can be accomplished by means of a threaded portion on the handle, and this threaded portion can be fixedly positioned over a range of distances, or if desire, the handle may comprise a pair of telescoping or sliding sections which are movable relative to each other.

A more detailed description of the invention follows in conjunction with a drawing, wherein:

Fig. 1 illustrates one embodiment of the wire brush of the invention with the wires pulled entirely into the interior of the handle and the adjusting rod extending out for its whole length;

Fig. 2 illustrates the wire brush of Fig. 1 ready for use, with the spiral spring adjusted for minimum entry of the rod into the handle;

Fig. 3 illustrates the wire brush of Fig. 1 ready for use, with the spiral spring adjusted for maximum entry of the rod into the handle;

Fig. 3a is a side or edge view of Fig. 3;

Figs. 4 and 5 illustrate two other embodiments of the wire brush of the invention with the handle provided with adjustable sections for changing the effective length of the handle; and

Fig. 6 shows another'e'mbodiment of the present invention.

Throughout the figures of the drawing, the

same parts are represented by the same reference numerals.

Referring to Figs. 1, 2, 3' and 3a in more detail, there is shown a wire brush or jazz drum switch comprising a tubular handle [0 of elliptical crosssection; a plurality or fine quality, thin gauge, rust-proof piano steel wires H held together at one end by a metallic lug or clip l2; and an adjustment rod [-3 having one end fixedly secured tcthe lug [2' and-its free end formed into a loop 15.

Thelug or clip I2 is crimped at IE to hold the steel wires firmly, and is slidable along the interior of the handle it in response to movement of the rod I3. It will be evident that this lug can have a different shape than that shown.

The handle l0 essentially comprises a tubular sleeve which-may be of any suitable'material such as metal or plastic. The end [8 of the sleeve is preferably flared.

Surrounding the loop portion 15 of the rod is a -spiralspringlll; In the process ofmanufacture, this spring is slidonto the rod before the end of the rod: is formed into a loop. The spring 20,

Pit should be noted, has one portion whose turns are very closely spaced and touch each other, as at 20, and has another portion 20" whose turns are more widely spaced. This spring acts in the manner of a worm in response to rotary motion of the fingers at any point on the spring. Thus, by turning the spring, the latter can assume the position shown in Fig. 2 or the position shown in Fig. 3, or any intermediate position. as shown in Fig. 1.

That end of the spring or worm which is located on the straight portion of the rod I3 is tightly wound and serves two purposes. First, it serves as a stop and prevents the spring from entirely leaving the straight portion of rod I3, and second, it acts as a limiting point for the entry of rod I3 into the handle. Thus, with the spiral spring. adjusted for the position of Fig. 2, the spring extends for its maximum permissible length on the straight portion of rod I3, and the rod extends for its minimum distance within the handle III. For the adjustment of the spiral spring shown in Fig. 3, the spring has a minimum permissible length on the straight portion of rod I3, and the rod extends for its maximum distance within the handle III.

In adjusting the spiral spring, the rod I3 is first pulled out for a substantial distance from the handle, and then the spring rotated by the fingers to assume the desired position, after which the rod is pushed back into the handle as far as it can go, with the left end of the handle resting against one end of the spring. In this position, the rod cannot move with normal use of the instrument, and the adjustment remains the same until the user again pulls out the rod to make another adjustment. The wires II, due to their tendency to spread out (their springiness, so to speak), exert a force on the rod I3 in such direction as to tend to pull the loop I5 toward the handle.

Fig. 1 shows the rod pulled out for its entire length, in which position the wires are concealed in the handle. This is the position in which the wire brush is carried when not being used, in order to prevent damage to the wires II.

Fig. 3 shows the greatest spread and greatest effective length of the wires, with the rod I3 pushed all the way into the handle as far as it can go.

Fig. 2 shows the smallest spread and smallest efiective length of the wires, with the rod I3 adjusted for minimum entry into the handle by virtue of the position of the spiral spring.

In the embodiment of Figs. 1, 2, 3 and 3a, it is important for the loop I5 to be so closed upon itself that the turns of the spiral spring cannot enter between the space between the straight portion of the rod I3 and the end of the loop which makes contact with the rod. This insures the fact that the spiral spring cannot leave the rod I3 entirely, and that only rotary motion of the spring is effective for adjusting the spring.

Figs. 4 and 5 show other embodiments of the invention which make use of an adjustable length handle.

In Fig. 4, the handle is designated I and comprises two threaded engaging portions A and B. Portion A is located at the end nearest loop I of the rod I3, and is adjustable in position over portion B to vary the effective length of handle I0, and hence the effective spread of wires II when the rod I3 is pushed all the way into the handle. A set screw C passing through a threaded aperture in portion A enables portions A and B to be fixedly secured together for a desired adjustment of the handle.

Fig. 5 is somewhat similar to the wire brush of Fig. 4 except that the adjustment of the effective length of the handle I0" is made at a location intermediate the ends of the handle. In Fig. 5 the two adjustable threaded engaging portions are designated A" and B, and are provided with a set screw C for securing these two portions together for any selected adjustment.

In Fig. 6, which shows another embodiment of the present invention, the wire brush comprises a rod I3 which is threaded for a small distance at the end which protrudes from the tubular sleeve or handle II]. There is provided in this embodiment a ball 2I of hard rubber or other suitable material which comprises a stop and which takes the place of the loop I5 of Figs. 1 to 5 inclusive. This ball or stop 2| may be threaded as shown and is adjustable in position over the threaded portion of the rod I3 by turning it in an obvious manner. The ball 2| is prevented from leaving the end of the rod I3 which protrudes from the sleeve I0 by means of a rivet or enlarged portion 22 which forms an enlarged end for the rod I3. It will thus be seen that turning the ball 2I Will adjust the position of this ball over the threaded portion of the rod I3 and determine the extent of entry of the rod I 3' into the tubular handle I0, hence controlling the spread of the wires II from the tapered end I8 of the handle.

A set screw 23 serves to fix the position of the ball 2| at any desired position along the length of the threaded position of the rod I3.
