Abstract
A drum brush comprising a tube with slot, a plurality of wire bristles, a rod and O-ring, where the said bristles are at least partially within said tube in which portions of bristles extend outwardly from one end of tube, the end of casing from which the bristles extend is partially flattened to hold the bristles in position. The tube has a slot, its relative position is perpendicular and near to the end from which the bristles extend. A rod of a diameter such that when inserted into the said slot is held in position and adjustable in length by sliding in and out of the tube. The said O-ring is slid over the tube and rod, its function is used to adjust the height or relative distance of the said rod to that of the bristles.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
(12) FIG. 1 depicts a cross sectional side view of one version of the drum brush with rod. The brush filaments 1 are inserted into a ferrule 2 and flared and crimped to ensure a secure fit, an epoxy can be used to increase the connection between these two components. The brush filaments can be comprised of metal wire or synthetic strands. Foam tape 18 is added to the ferrule to reduce and eliminate rattle between the ferrule and the tube. The ferrule is comprised of metal. The slot 14 is made starting approximately one inch from one end of the tube. The tube is flattened at 3 such that the flatten area is perpendicular to the slot 14. The brush filaments with ferrule 2 and foam tape 18 are inserted brush end first into the tube at 8 and slid to the forward position through the area at 3 so that the brushes flair out in a fanned configuration when exiting the tube 4. The tube 4 is further flattened at 3 to ensure a secure fit between the tube and the brush filaments 1 in a fanned configuration 1. The end cap 6 is inserted into the end 8, an optional metal type rivet with domed head 7 is drilled into the end cap 6. The outer sleeve 5 is slid over the tube. The cut 13 is made in the outer sleeve 5. The rod 9 is inserted through the cut 13 and slot 14 into the tube 4 space 20. The small O ring 11, the bead 10 followed by the O ring 12 are then placed onto the rod 9 and slid to a predisposed position as depicted in the FIG. 1 and in the overhead view in FIG. 3.
(13) The 3 large O rings 15, 16, 17 are slid over the cap 6 and slid into a position over the outer sleeve 5 or the rod 9 as depicted in FIG. 1, FIG. 2 and FIG. 3.
(14) FIG. 2 depicts a head on view of the embodiment at 2A of FIG. 1 and FIG. 3 showing the brush filaments 1 in a fanned out configuration with the rod 9 with bead 10 at a position centered and above the brush bristles 1.
(15) FIG. 4 depicts an overhead view of the tube 4, the material composition of the tube can be one of metal such as aluminum or brass or a synthetic material such as polycarbonate. The slot 14 shown in FIG. 4 is milled or drilled at its position prior to further assembly of the embodiment depicted in FIG. 1. The slot is approximately inch wide and 1 inch long. It is positioned approximately 1 inch back from the one end of the tube 4. An initial flattening of the area 3 is also done at the end near the slot 14. The flatten area 3 is perpendicular to the slot as depicted in FIG. 4.
(16) FIG. 5 depicts another embodiment in which the tube 4 depicted in FIG. 8 in which the sleeve 5 has been slid over the tube 4 and cuts 13 and 19 have been cut into position at the midpoint of slots 14 and 25. Rod 9 is inserted through cut 13 and slot 14 and rod 21 is inserted through cut 19 and slot 25. Optional O rings 11, 12 and bead 10 are shown in a predisposed position on rod 9 and optional O rings 23, 24 and bead 22 are shown in a predisposed position on rod 21.
(17) FIG. 6 depicts a side view of the embodiment shown in FIG. 5.
(18) FIG. 7 depicts yet another embodiment in which one longer nylon rod 9 inserted though cut 13 and slot 14 and its opposite end is inserted through cut 19 and slot 25.
(19) FIG. 8 depicts the tube 4 with slots 14 and 25 that is used in the embodiments of the invention as depicted in FIG. 5 and FIG. 6 and again in FIG. 7 and FIG. 10.
(20) FIG. 9 is an enlargement showing the cuts 13 and 19 and slots 14 and 25 of the area 9A shown in FIG. 5 and FIG. 7.
(21) It will be appreciated that the rods 9 and 21, depicted in FIG. 1, FIG. 2, FIG. 3, FIG. 5 and FIG. 7 of the drum brush with rod invention may be fabricated of any synthetic material such as polypropylene, nylon, polycarbonate PVC or ABS plastics which has the required degree of stiffness and resilience desired to form sufficient bounce and strength as intended for this invention. The diameter of the rods may vary in accordance with the width of the slots. It will be appreciated that the width and length may vary to suit the diameter and rod sizing. It will also be appreciated that the brush filaments may be comprised of suitable wire comprised of brass, steel or nylon. The over lying outer sleeves can be comprised of suitable rubber, PVC or shrink material. It will also be realized that the O rings and beads as depicted are moveable and removable from their predisposed positions and therefore become an optional feature of the invention. The rod or rods as depicted are moveable and removable from their respective positions.
