PROVISIONAL SPECIFICATION.
Improvements in Cleaning Rods for Rifles and other Firearms.
I, CHARLES RIGBY ALLPORT, of 72 St. James Street, London, S.W., Gunmaker,
do hereby declare the nature of this invention to be as follows :-
My improvements relate to cleaning rods for rifles and other firearms in which
the heads carrying the cleaning cloth or other material are arranged to rotate on
the rod. Heretofore the rotating head has been secured on to the end of the rod
by means of a nut screwed on to the threaded end of the said rod after the same
has been passed through the hole in the revolving head. This arrangement is
objectionable from two points of view, firstly, the aforesaid nut is liable to become
unscrewed and the head to be thereby detached from the rod and to remain in the
bore, and secondly, the presence of the nut prevents the attachment of a brush to
the revolving head.
By my improvements the revolving head is so secured to the rod that it cannot
possibly come off, and a brush may be secured to the head with great facility.
My invention consists, firstly, in turning or otherwise forming, one or more
circumferential grooves in the cylindrical part of the cleaning rod which enters
the revolving head, and on which the said head turns; and secondly, in pressing
the material of the revolving head at the part or parts thereof which comes or
come opposite to the aforesaid groove or grooves in the rod (when the said head
is placed on such rod) radially inwards so as to project into the said groove or
grooves and to form a fillet or fillets round the inside of the said head which
correspond to and take into the groove or grooves on the rod and effectually
secure it thereon while leaving it free to rotate. This device leaves the outer end
of the revolving head available for having a brush screwed or otherwise secured
thereto and the head may also be furnished with the slot usually employed in plain
cleaning rods, not provided with revolving heads, for the purpose of having the
strip of cloth or other cleaning material passed through it in the usual way.

COMPLETE SPECIFICATION.
Improvements in Cleaning Rods for Rifles and other Firearms.
I, CHARLES RIGBY ALLPORT, of 72 St. James Street, London S.W. Gunmaker,
do hereby declare the nature of the said invention and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying sheet of Drawings, and
to the letters and figures marked thereon, that is to say
My improvements relate to cleaning rods for rifles and other firearms in which the
heads carrying the cleaning cloth or other material are arranged to rotate on the rod.
Heretofore the rotating head has been secured on to the end of the rod by means of a
nut screwed on to the threaded end of the said rod after the same has been passed
through the hole in the revolving head. This arrangement is objectionable from two
points of view, firstly, the aforesaid nut is liable to become unscrewed and the head to
be thereby detached from the rod and to remain in the bore, and secondly, the
presence of the nut prevents the attachment of a brush to the revolving head.
By my improvements the revolving head is so secured to the rod that while

page_text: perfectly free to revolve thereon it cannot possibly come off, and a brush may be
attached to the head with great facility.
In the Drawings hereto annexed Figure 1 is an elevation of the end of a cleaning
rod with a revolving head applied thereto in accordance with my invention, Figure 2
is a similar elevation but with the revolving head shown in section.
My invention consists, firstly, in turning or otherwise forming, one or more
circumferential grooves A in the cylindrical part of the cleaning rod B which
enters the revolving head C, and on which the said head turns; and secondly, in
pressing the material of the revolving head C at the part or parts thereof which
comes or come opposite to the aforesaid groove or grooves A in the rod (when
the said head is placed on such rod) radially inwards as shown at C in the figures
so as to project into the said groove or grooves A and to form a fillet or fillets C²
round the inside of the said head which correspond to and take into the groove or
grooves A on the rod and effectually secure it thereon while leaving it free to
rotate. This device leaves the screwed outer end C³ of the revolving head available
for having a brush screwed or otherwise secured thereto, and the head may also be
furnished with the slot D usually employed in plain cleaning. rods, not provided
with revolving heads, for the purpose of having the strip of cloth or other cleaning
material passed through it in the usual way.
The end B of the cleaning rod B is preferably made pointed so as to offer as little
resistance to the rotation of the head C as possible.
The head C may be made of any suitable material such as brass or steel for
example, but when made of steel there is danger, in some cases, of its cutting or
scratching the interior of the barrel of the gun, or injuring the rifling; on the other
hand, when made of brass, the internal fillets Care liable to wear away quicker than
the steel rod on which they turn. To obviate these inconveniences I sometimes employ
the modification shown in Figures 3 and 4 in which I first place a steel tube E next the
rod B, pressing the parts E¹ of such tube into the grooves A of the rod so as to
form fillets therein similar to those marked C² in Figure 2. I then pass over the steel
tube E the brass head C, soldering the two together by sweating or otherwise, and I
then press the parts C₁ of the head C into the grooves made round the outside of the
tube E in the operation of forming or pressing the parts E¹ into the grooves A
whereby the head C is prevented from coming off the tube E in the event of the
soldering or other means of connection giving way.
By the means shown in Figures 3 and 4 I secure on the one hand the employment
of the harder material (steel) to resist the wear and tear caused by the rotation of the
head on the rod, and on the other the employment of the softer material (brass) for
the part liable to come in contact with the bore or rifling of the gun.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that. what I
claim is :-
In cleaning rods for rifles and other firearms, securing the revolving head to the
rod by forming one or more circumferential grooves in the rod and pressing part of
the material of the head radially into such groove or grooves so as to form a fillet or
fillets therein as hereinbefore described, and illustrated in the Drawings hereto
annexed.
