Abstract

The present disclosure provides spindle brushes and methods of using the same. The spindle brush may comprise a plurality of bristles located in a generally cylindrical cavity and handles located laterally relative to the bristles. The spindle brush may also include a smooth interior wall to the rear of the bristles to confirm that debris has been removed from the spindle.

Claims (21)

1 . A spindle brush comprising:

a brush body comprising a front, a rear, a thickness extending from the front to the rear, a left side, a right side, a width extending from the left side to the right side and perpendicular to the thickness, a top, a bottom, a height extending from the top to the bottom and perpendicular to the thickness and the width, at least one generally cylindrical wall comprising an interior surface defining a generally cylindrical cleaning cavity, the generally cylindrical cleaning cavity being hollow and extending from the brush body front to the brush body rear, the at least one generally cylindrical wall interior surface comprising a forward segment comprising a plurality of bristles, said bristles arranged in rows that are spaced about a circumference of the forward segment of the generally cylindrical wall interior surface, each bristle extending from the generally cylindrical wall interior surface towards the generally cylindrical cleaning cavity,

wherein the brush body comprises a pair of handles located laterally relative to the generally cylindrical cleaning cavity on the brush body left side and the brush body right side, the handles each comprising a handle hole configured to receive fingers of a human and a handle wall extending around the handle hole; and further

wherein the at least one generally cylindrical wall interior surface further comprises a rear segment located to the rear of the forward segment, the rear segment being generally smooth and lacking bristles.

2 . The spindle brush of claim 1 wherein said bristles are wire bristles.

3 . The spindle brush of claim 1 wherein the plurality of bristles are also arranged in columns that are parallel to the brush body thickness and perpendicular to the rows.

4 . The spindle brush of claim 3 , wherein the rows are spaced approximately evenly apart, and the columns are spaced approximately evenly apart.

5 . The spindle brush of claim 1 , wherein the thickness of the forward segment, as measured from the front to the rear of the forward segment, is approximately equal to the thickness of the rear segment, as measured from the front to the rear of the rear segment.

6 . The spindle brush of claim 1 wherein the bristles jut/extend slightly further interior into the generally cylindrical cleaning cavity as compared to the rear segment of the at least one generally cylindrical wall interior surface.

7 . The spindle brush of claim 1 wherein the brush body is comprised of a main body and a removable insert comprising the bristles, the removable insert attached to the main body by one or more fasteners.

8 . The spindle brush of claim 7 wherein the brush body comprises a ledge and further wherein the removable insert rests on the ledge.

9 . A method of cleaning a spindle comprising:

a) providing the spindle brush of claim 1 ;

b) placing the brush body rear directly in front of the spindle;

c) moving the brush body forwardly to place the spindle in the generally cylindrical cleaning cavity, and

d) moving the brush body forwardly and rearwardly and/or rotating the brush body relative to the spindle to clean the spindle with the bristles.

10 . The method of claim 9 , wherein the method further comprises:

e) inverting the brush body;

f) moving the rear segment over the spindle so that it surrounds the spindle.

11 . The method of claim 10 wherein the at least one generally cylindrical wall comprises an exterior surface opposite the interior surface of the rear segment, and wherein the method further comprises placing the exterior surface against a hub bore of a hub configured to mount to the spindle to determine if the hub bore is out of round and sufficiently deep.

12 . The method of claim 9 wherein the method further comprises wrapping the fingers of a human's hand around the handle walls to grip the spindle brush.
