## Abstract

A device for preventing loosening of a drum's tension rods is presented. The device generally includes an elongated body extending along a first axis between first and second ends and having a first opening formed therethrough adjacent the first end and along a second axis that extends perpendicular to the first axis; first and second side edges that extend in spaced relation to one another and between the first and second ends; a second opening that extends through the first side and into the first opening along a third axis that is perpendicular to the first and second axes; and a set screw that is movably installed within the second opening and can extend into the first opening.

## Claims

### Claim 1

A device for use on a circular shaped drum defining a circumference, a drum head that extends in a first plane, a rim that extends around the circumference of the drum, and a plurality of tension rods each of which extends along a rod axis that is perpendicular to the first plane, wherein the device prevents rotation to a drum's tension rods when installed on the drum, said device comprising:
a. an elongated body extending along a first axis between first and second ends and having a first opening formed therethrough adjacent said first end and along a second axis that extends perpendicular to said first axis, first and second side edges that extend in spaced relation to one another and between said first and second ends, and a second opening that extends through said first side edge and into said first opening along a third axis that is perpendicular to said first and second axes; and
b. a set screw that is movably installed within said second opening and is extendable into said first opening.

### Claim 2 (depends on 1)

The device according to claim 1, wherein said second side comprises a contoured region that is adapted to comfortably receive a finger.

### Claim 3 (depends on 1)

The device according to claim 1, wherein said first opening is non-circular is shape.

### Claim 4 (depends on 3)

The device according to claim 3, wherein said first opening is star-shaped.

### Claim 5

A method for installing a device on a drum that defines a circumference and includes a drum head that extends in a first plane, a rim that extends around the circumference of the drum, and a plurality of tension rods each of which extends along a rod axis that is perpendicular to the first plane, and a lug mounted on each of the plurality of tension rods to permit tightening or loosening thereof, the device having an elongated body extending along a first axis between first and second ends and having a first opening formed therethrough adjacent the first end and along a second axis that extends perpendicular to the first axis, first and second side edges that extend in spaced relation to one another and between the first and second ends, and a second opening that extends through the first side edge and into the first opening along a third axis that is perpendicular to the first and second axes, and a set screw, the device adapted to prevent loosening of the tension rods when playing the drum, the method comprising the steps of:
a. tightening each tension rod to a desired degree;
b. positioning the device on the drum such that a lug extends through the first opening and the second side edge extends tangentially to the circumference of the drum; and
c. tightening the set screw in the second opening to secure the positioning of the device on the lug.
