8 Claims.

This invention relates' to musical instruments, and more particularly to wire brushes, sometimes referred to as jazz drum switches.

The-wire-brush is used with the drum or cymbal to obtain patter and swish-like sound effects. It comprises a tubular handle having at one end a plurality of thin gauge steel wires which spread out in thel 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 xedly connected at one end to the lug in the interior of the handle. The other end of the rod terminatesVV in a loop or a ball located outside the handleto" enable the rod to b'e easily grasped by the hand and' moved along the longitudinal axis of the handle, thereby permitting adjustment of theA effective length and the spread of the wires.

One diiliculty experienced with known types of Wire brushes'Vl is that the length of the rod which protrudesfrom the handle changes for different adjustments of the wires, thus interfering with they balance or feel of the instrument in the hand ofthe user.

Another difhculty is caused by undesired changes inf adjustment ofv thev wires during usage, due' to inadvertentmovementof the rod.

The present invention overcomes the foregoing difficulties.

According to the invention, the rod is threaded at* the end nearest they wires to permit adjustment of the eiective lengthr and spread of the wires. The free end of the rod at which the loop islocatedI alwaysmaintains the same position on the handle for all adjustments, when the wire brushv is ready for use with aA drum. Atthey end of the handle nearest the loop, there isprovided a groove or' slot which is suiiiciently wide to accommodate the lower end of the loop and thus lock the rod on the handle, thereby preventing undesired: movement of the r'od during usage.

The following is a description of the-wire'A brush of the invention, in conjunction with a drawing, wherein:

Fig; 11 illustrates the wire brush of the invention with the wires pulled entirely into the interior of the handle and the adjusting rod. eX- tending out' for. its Whole length;

Fig. 2 illustrates the wire brush ready for use., The thin wires are spread out in the manner of a fan, and the rod is locked in position on the handle;

Fig. 3 is a side or edge View of Fig. 2;

Fig. 4 is an enlarged fragmental View of Fig. 2 insection;

Fig. 5 is a view similar to that of Fig. 4 and shows the adjustment of the rodV` for a smaller spread of the Wires;

Fig. 6 is a cross-section of Fig. 4 along the line 5*-6; and

Fig. 7 is a cross-section of Fig. 4 along the line 'l-'L Throughout the iigures of the drawing, the same parts are indicated by the same reference numerals.

Referring to the drawing in more detail, there is shown a wire brush or jazzdrum switch comprising a tubular handle I of elliptical crosssection; a plurality of fine quality, thin gauge, rustproof piano steel wires- II held together at one end by a metallic lug or clip I2; and an adjustment rod I3 having one end I4 threadedly engaging an extension of the lug I2 and its free end formed intol a loop I5.

The lug or clip I2 is crimped at I6 to hold the steel wires firmly, and is slidable along the intei'ioroi the handle. It will be evident that this lug can have a diierent shape than that shown and eliminate the extension, if desired, without departing from the principles of the invention.

The threaded end i4 of the rod I3 is provided with a large end (such as a nut) in the interior of the lug or clip I E. This nut forms a stop, to limit threaded movement of the rod at one extreme position and also prevent the rod from coming loose from the lug.

rhe handle I0 essentially comprises a tubular sleeve Il which may be of any suitable material such as metal or plastic. The end I8 of the sleeve I'I, which is nearest the lug l2, is preferably flared. The other end of sleeve Il is slotted at 2B to accommodate the loop I5 when the rodv I 3 is pushed all the Way into the sleeve. In this position, the slot locks the rod in position on the handle. Although the handle has been shown as elliptical in cross-section, it may, if desired, be circular.

Surrounding the tubular sleeve I'I is, optionally,

a. soft or moulded rubber covering I9 to furnish a good gripping surface for the user. The rubber covering I9 may be eliminated, and, if desired, the sleeve I'I made of moulded rubber.

In making an adjustment of the effective length and spread of the wire brush, the rod I3 is rst pulled out a short distance from the slot 20 and the rod then turned (rotated) until the desired amount of spread and length of wires is obtained. The rod is then pushed. back into the handleY as far as it can go, with the loop resting in the groove or slot 20, as shown in Figs. 2, 3 and 4. 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 I into the slot 20 and hold it in this position. In this position, the rod cannot move with normal use of the instrument, and the adjustment remains the same until the user again pulls the rod out to make another adjustment at which time the same procedure is repeated. It will be seen that the slot in effect acts as a lock to prevent inadvertent change in adjustment of the wires.

Since the rod I3 is pushed back into the handle and the loop I5 always rests in the groove 2U after an adjustment is made, regardless of the effective length and spread of the wires, the rod I3 will always maintain the same position on the handle during usage and. the instrument will furnish the musician with the same feeling of balance.

Fig. 1 shows the rod pulled out for its entire length. in which position the wires are hidden 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 I I.

To obtain the greatest spread and greatest effective length of the wires, the rod is pushed all the way into the handle with the threaded. end I4 assuming the position shown in Fig. 4.

Fig. 5 shows the threaded end of rod I 3 almost as far into the lug or clip I2 as it can go. In this position the effective length and spread of the wires is a substantial minimum. The wires are hunched together more closely in Fig. 5 than in Fig. 4 and will produce a louder sound for the same force exerted on the switch.

What is claimed is:

1. A musical instrument comprising a wire brush having a tubular handle open at both ends, a plurality of wires adapted to protrude from one end of the handle, a rod in the interior of said handle and extending from the other end of said handle for adjusting the effective length and spread of the wires, and means on said rod cooperating with one extreme end of said handle for locking said. rod in position for different playing adjustments of said wire brush.
