`ANNULAR BRUSH

`

`(CI. 15—164)
`
`i
`This invention relates to brushes, and has for
`its objects the provision of an annular
`one of
`brush having an annular body of bristles that
`project radially and which body is supported
`from the handle in a manner that insures against
`detrimental distortion of the brush when in use.
`Another object of the invention is the provision
`of an annular brush having an annular body of
`bristles with the center of the body substantially
`open to permit dirt and foreign material to pass
`through the same and which brush is provided
`with a handle extending axially of the body and
`at one side thereof.
`Heretofore brushes intended for use in clean
`ing cylindrical, or generally cylindrical vessels,
`or shallow circular pans, have normally been
`generally U-shaped with the handle projecting
`from one side of the U. Usually in brushes of
`the type having the bristles secured between
`twisted wires, the ends of the U have been ex
`tended to either form a handle or for secure-
`In many instances,
`ment of the handle thereto.
`it is practically impossible to use the conventional
`brushes in cylindrical vessels, either because the
`is too deep and one of its sides interferes
`vessel
`with the handle, or because the largest side of
`the brush cannot be flat on the bottom, and con
`tact between the brush and the bottom or lower
`is only with the bristles at
`corner of the vessel
`the tip end of the brush.
`Also in conventional brushes that have here
`tofore attempted to make arcuately extending
`bodies at the end of a handle for use in cylin
`the
`drical or substantially cylindrical vessels,
`outer end of the brush or brush body is unsup
`ported and a cleaning pressure cannot be ap
`plied without permanently bending the body.
`One of the objects of the present invention is
`the provision of a brush that has none of the
`above objections and that is cheap and easy to
`make and string, and which brush will readily
`reach the curved lower corner of a cylindrical
`vessel at any side of the latter and that may be
`rotated on its central axis with the application
`injury to the
`of appreciable pressure without
`brush or detrimental distortion thereof.
`Insofar as the present brush is concerned, the
`provision of an annular brush with an axially
`extending handle, and which brush is adapted
`to simultaneously clean the bottom and the sides
`of a vessel along its lower corner and along the
`line of the juncture between said sides and bot
`tom with the minimum of effort and with maxi
`mum efficiency is another object of the inven
`tion.
`
`Other objects and advantages will appear in
`the description and in the drawings.
`In the drawings, Fig. 1 is a perspective view of
`the brush with the twisted wire support for the
`same clearly emphasized to show the structure
`of the support.
`Fig. 2 is a sectional view as seen from line 2—2
`of Fig. 1.
`3 is an enlarged sectional view taken
`Fig.
`through one side of the annular body of bristles
`to indicate the radial directions of the bristles.
`the invention the
`In the preferred form of
`is annularly
`brush head, generally designated I
`shaped and is formed from a single length of
`twisted wire.
`The opposite end portions 2, 3 of the said wire
`(two wires twisted together form the one length
`into
`of wire) may extend substantially parallel
`one end of a handle 4 in which they are securely
`held. The handle 4 shown herein is elongated
`so as to extend longitudinally of the end por
`tions 2, 3, although it is to be understood that for
`certain uses the handle may be of another shape.
`Intermediate the end portions 2, 3 of said sin
`gle length of wire, the latter is formed to provide
`an annular support 5 for bristles 6.
`These bristles are held between the two wires
`that are twisted together to form the single
`length having end portions 2, 3, and the bristles
`project radially from two sides of the portion 5.
`Thus an annular torus-shaped, centrally open,
`body of bristles is provided.
`Between end portions 2, 3 of the brush and
`the annular portion 5, portion 2 is formed to
`provide a laterally projecting loop 7 that extends
`over one side of the annular support 5, and the
`end of this loop opposite the end that connects
`with portion 2 is then extended, as at 8, to the
`side of the annular support 5 that is opposite
`that over which loop 7 extends and integrally
`connects with one end of said portion 5.
`The lower end of the portion 3 extends laterally
`as at 9 to the point where the portion 8 connects
`with the annular portion 5, where it joins the
`other end of said annular portion.
`Where portions 8, 9 join the end of the portion
`of the wire forming the annular brush support,
`they may be twisted together as indicated at 10
`in the drawings.
`Only the circular or annular section 5 of the
`length of wire need have the bristles 6, and the
`remainder may be bare. The bristles themselves
`may be of any material suitable for brushes and
`for whatever use the brush is intended.
`By the foregoing structure, it is seen that the

`
`brush is well balanced since the handle is coaxial
`with the annular body of the brush. The entire
`lower side of the annular body of bristles may be
`readily placed flat on the bottom of a vessel with
`equal pressure at points around the body. The 5
`loop 7 supports the side of the body opposite its
`connection with portions 8, 9, and these latter
`portions also strengthen the head.
`When in a vessel and on the bottom, as above
`mentioned, the brush can be given,a rotary move- 10
`ment or a revolvable movement, and the corners
`of the vessel will be cleaned as well as the sides
`adjacent said lower corners.
`Any foreign material will readily pass through
`the center of the annular brush at opposite sides 15
`of the loop 7 or portions 8, 9, or .they .may .pass
`through the loops provided by these portions.
`I claim:
`A brush comprising a length of wire formed to
`provide an annular support for bristles, bristles 20
`.projecting radially outwardly from said support
`at all points around the same and in all direc
`tions normal to the axis of said wire to form a
`torusTShaped brush, one end portion of said wire
`extending radially inwardly from a point on said 25
`
`support to a point adjacent the central axis of
`said support and then axially thereof, the other
`end portion of said wire extending generally dia
`metrically across said support from said first men
`tioned point to the opposite side of said support
`and in engagement with the latter and back to
`a point adjacent said central axis and axially
`thereof alongside said first mentioned portion to
`form a handle.
