GUN CLEANING DEVICE
Abstract
A gun cleaning device is formed of a rod having at one end a
handle and at the other end a cleaning member or a holder therefor.
The handle is slidable through a hole in a permanent magnet. On the
face of the magnet directed towards the cleaning member there are
laterally extending fingers of a non-metallic material such as
rubber or plastic to prevent contact between the rod and the barrel
and an extending nipple which fits into the gun barrel and guides
the rod.

Claims
I claim:
1. A cleaning device for guns comprising a rod having a handle at
one end and means at the other end to hold a cleaning element and
having a longitudinal axis, and a guide member slidable on the rod
in the direction of said longitudinal axis and having a guard
member extending transversely to the longitudinal axis and having
one face directed along the longitudinal axis and a nipple
extending from such face in the direction of the longitudinal axis
substantially coaxial with the longitudinal axis and of
substantially less cross-section at all points in a plane
transverse to the longitudinal axis than the greatest transverse
dimensions of at least the exterior of said guard member, said
nipple and said face of the guard member being formed of a material
which is non-injurious to the metal of a gun barrel, and a
permanent magnet secured to the guard member on the side thereof in
the direction of the longitudinal axis opposite to said face,
whereby to hold the guide member on the muzzle of a gun with the
nipple extending into the muzzle during reciprocation of the rod
therein.
2. A device as claimed in claim 1, in which the guide member
includes a cup on the other side in the direction of the
longitudinal axis from the guard member enclosing the magnet.
3. A device as claimed in claim 2, in which said handle includes at
least a central metallic part of magnetizable material at the end
thereof from which said rod projects.
4. A device as claimed in claim 3, in which a metallic securing
member is fixed in said magnet and extends through said cap to the
side thereof in the direction of the longitudinal axis remote from
the magnet.
5. A device as claimed in claim 1, in which said handle includes at
least a central metallic part of magnetizable material at the end
thereof from which said rod projects.
6. A device as claimed in claim 5, in which a metallic securing
member is fixed in said magnet and extends through said cap to the
side thereof in the direction of the longitudinal axis remote form
the magnet.
7. A centering and holding device for gun cleaning rods comprising
a guide member including a guard member having a hole therein with
a longitudinal axis and extending laterally with respect to the
longitudinal axis and having one face directed along the
longitudinal axis and a nipple extending from such face in the
direction of the longitudinal axis substantially coaxial with the
longitudinal axis and of substantially less cross-section at all
points in a plane transverse to the longitudinal axis than the
greatest transverse dimensions of at least the exterior of said
guard member, said nipple and said face of the guard member being
formed of a material which is non-injurious to the metal of a gun
barrel, and a permanent magnet secured to the guard member on the
side thereof in the direction of the longitudinal axis opposite to
said face, whereby to hold the guide member on the muzzle of a gun
with the nipple extending into the muzzle during reciprocation of a
cleaning rod therein.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a cleaning device for guns.
2. The Prior Art
Various arrangements are known for guiding a cleaning rod so as to
center it in the muzzle of a gun barrel. All of these however are
either complicated or expensive or unsatisfactory and
inefficient.
SUMMARY OF THE INVENTION
The gun cleaning rod according to the invention is provided with a
handle on one end and a gun cleaning device on the other end. The
body of the rod is slidable through a disk of permanent magnetic
material enclosed in a cup. On the side of the magnet facing the
cleaning tool there are laterally projecting fingers of a soft or
non-metallic material with a nipple extending therefrom for
engagement into a barrel of the gun.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows in side elevation a gun cleaning device embodying the
invention;
FIG. 2 is a cross-section on the line 2--2 of FIG. 1;
FIG. 3 is a cross-section on the line 3--3 of FIG. 2;
FIG. 4 is a cross-section on the line 4--4 of FIG. 1.
Referring to the drawings, there is a rod 2, preferably of round
cross-section, of whatever is needed for cleaning the gun. This rod
may be formed in several parts separated by threaded joints at 4,
so that it can be made as long as desired and can be taken down for
packing. One end section of the rod is secured in a metal sleeve 6
held in a plastic handle 8 and projecting slightly therefrom as
shown at 10. The other end of the rod has a threaded joint 12 for
attachment of a cleaning tool, such as a wire brush 14, a holder
for cleaning rods or the like.
Slidable along the cleaning rod 2 is a permanent magnet 16 set in a
rubber or plastic cup 18, and projecting slightly therefrom on the
face of this magnet opposite cup 18 is a plastic member having a
tapered nipple 20 extending therefrom and adapted to fit into the
muzzle of the gun to be cleaned and having fingers 22 extending
laterally therefrom.
The magnet need not be round but may be of any suitable shape so
long as it is substantially wider than the thickness of the nipple
20 and the fingers 22 can be of any suitable shape or may
constitute simply a continuous annular member.
When the device is to be used, it is positioned at the muzzle of
the gun with the cleaning tool extending into the barrel and the
nipple 20 extending into the mouth of the barrel. The magnet 16 is
of sufficient strength to hold the guide member in position at the
mouth of the barrel while the rod is reciprocated therethrough to
clean the gun. The nipple 20 centers the device in the barrel and
prevents any contact between the cleaning rod and the mouth of the
barrel, thus preventing damage to the barrel. The fingers 22
constitute a shield to protect the mouth of the barrel from contact
by the magnet itself, which is of hard material.
When cleaning is finished, a pull on the rod sufficient to overcome
the magnetism of the magnet 16 will remove the rod completely from
the barrel.
When the device is to be packed, the guide member is moved to the
portion of the rod adjacent the handle 8. The magnet has sufficient
strength to hold the guide member rather securely through magnetic
attraction to the sleeve 10. Thus the guide member is prevented
from loss when the device is not in use.
The nipple 20 may be of any soft or smooth surface material which
will not scratch or mar the metal of the body. It is preferably
made of plastic, which may then be comparatively rigid.
The magnet is secured in the cap 18 by an annular rivet 24 which is
brazed, welded or otherwise secured in the magnet and which extends
through the cap 18 and is riveted at 26 against the side of the cap
remote from the magnet. This member cooperates with the sleeve 10,
transferring the magnetic flux to the sleeve.
