Improvements in Gun Swabs or Cleaners.
I, GEORGE HENRY GARRISON of Sumas, in the County of Whatcom and
State of Washington, United States of America, Railroad Ticket Agent, do hereby
leclare the nature of this invention to be as follows:—
This invention relates more especially to means whereby the swab or cleaner
proper may be expanded by direct or independent pressure applied from the
outer end of the rod or handle, to any required size after the cleaner has been
inserted in the barrel whereby the diameter of the cleaner may be readily adjusted
to suit all parts of a choke bore for example.
The rod is tubular and made in lengths joined together by screw-ferrules and
sockets and, at the end to which the swab or cleaner is attached, is provided with a
telescopic sliding joint formed of an inner male member and an outer female member
or socket, one of said members being connected to the tubular rod and the other to
an inner thrust rod passing through it towards the handle. The swab or cleaner
may be of felt or cloth covered rubber or a split metallic one or of any other con-
struction adapted to be expanded by end pressure between disc-like heads or
washers. The pressure is applied to the outer head through a central longitudinal
stem passing through the swab or cleaner and screwed to the male member of the
telescopic joint whilst the other disc or washer is directly pressed by the other
member of said telescopic joint when the two members are moved in opposite
directions by means of the inner thrust rod above referred to whereby the swab or
cleaner will be expanded as required. The thrust rod is connected to the female
member of the telescopic joint by a cross-pin working in longitudinal slots in the
hollow male member and said rod is also constructed in lengths to conform to the
lengths of the outer tubular rod, these thrust rod sections being guided in their
longitudinal movement and restrained from falling out of their respective outer rod
sections, when the outer rod is disjointed, by rivets, pins, or screws, passing trans-
versely through the outer rod or its ferrules and through slots in the inner rod sections.
The several inner rod sections are preferably made to centre with each other at
their meeting ends, by coned joints, so that they will virtually form a straight
continuous rod. The thrust rod is actuated by a lever pivoted in a split strap
encircling the outer rod near its handle, the short arm of the lever passing through a
A spring confined
slot in the tube and bearing against the end of the thrust rod.
between a head on the thrust rod and an abutment on the outer tube retracts the
thrust rod.
By means of this device, the swab or cleaner may be readily entered within the
gun and be distended or spread laterally by direct pressure applied to it, after it has
been put into the gun, and be adjusted to give any required pressure against the
sides of the barrel, it only being necessary to apply the requisite force to the thrust
rod to move it forward while the outer rod is held firmly by the hand and this may
readily be done by pressing on the handle portion of the lever.
Any standard gun cleaner as now made can be used when desired on the outer or
main rod without the inner rod direct pressure attachment.

Improvements in Gun Swabs or Cleaners.
1, GEORGE HENRY GARRISON of Sumas, in the County of Whatcom and
State of Washington, United States of America, Railroad Ticket 'Agent, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates more especially to means whereby the swab or cleaner
proper may be expanded by direct or independent pressure applied from the outer
end of the rod or handle, to any required size so as to exert the necessary pressure
against the sides of the barrel after the cleaner has been inserted therein, and the
invention consists in a gun cleaner rod of novel construction including attached
adjusting means whereby the above named object is very efficiently and expeditiously
effected, substantially as hereinafter described and more particularly pointed out in
the claims. By this invention the great objection to other gun cleaning devices
generally is avoided, namely the unsatisfactory adjustment when the pressure
to act upon the sides of the barrel is produced by tightening up the cleaner, as for
instance by a screw, before putting the cleaner into the barrel and in which when
the adjustment is made to adapt the cleaner to fit the breech of a gun, makes it too
large when shoved down toward the muzzle in choke bore guns, thus requiring new
or repeated adjusting.
Reference is to be had to the accompanying drawings, forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in
all the figures.
Figure 1 represents an exterior longitudinal view of a gun swabbing or cleaning
device embodying my invention and comprising a tubular main or outer rod or stick
and inner longitudinally movable rod, both shewn as constructed in three sections
or lengths, with a swab applied to the forward end of the front outer member and
a lever applied to the rear member or handle portion of the device for moving the
inner rod forward to give the necessary pressure to and lateral distension of the
.swab.
Figure 2 is a longitudinal central section, upon a larger scale, extending from
2 to 2 in Figure 1, of the forward portion or front section of the whole device,
including the swab or cleaner.
Figure 3 is a further longitudinal section, extending from 3 to 3 in Figure 1, of
the intermediate and rear members, in part, of the device.
Figure 4 is a longitudinal sectional view, extending from 4 to 4 in Figure 1, of
the rear member, in part, of the device, with attached lever for actuating the
inner rod.
Figure 5 is an exterior longitudinal view of the portion shewn in Figure 4,
looking in a plane at right angles, to the latter figure, and
Figure 6 is a transverse sectional view, upon the line 6-6 in Figure 5,
omitting the lever and central or inner rod.
While the device is here shewn as constructed in three main sections or lengths
detachably jointed together, it is not necessarily restricted to any number of such
sections or pieces. I prefer, however, to make it in three pieces and it will
here be described accordingly.
A', A2, A3, indicate the three members or lengths of the outer rod which is
hollow or tubular and supposed to be made of wood. Said members or lengths
are detachably connected together at their meeting end joints by screw-threaded.
metal ferrules b, c, and the front member A is fitted with a cap-like ferrule
extending above it and of reduced diameter externally for a portion of its length,
to receive over it a longitudinally-sliding compressing ferrule B which when forced
forward or outward serves to produce lateral distension of the swab C to give it the
necessary pressure on the sides of the barrel, To this end the swab or cleaner C

page_text: is, or may be supposed to be, made of felt or other soft and flexible material with
a screw e passing centrally through it and engaging at its inner end with the cap-
like ferrule d which is fast on the outer member A. The head of this screw or a
washer under its head, binds the swab at its outer end while a washer and nut g
screwing over and passing beyond the threaded end of the screw, act as a follower
on the inner end of the swab and lie against the outer end of the sliding com-
pressing ferrule B, so that when the latter is forced outward, the swab will be
distended or expanded laterally as required. Instead of a felt swab a cloth-covered
rubber one similarly bound and held might be used, or a well-known split metallic
one be readily remodelled to conform, for operation in like manner; in fact I do
not restrict myself to any particular material of which to construct the swab.
i
The direct pressure to expand the swab laterally after it has been put into the
barrel of the gun is produced by the longitudinally movable inner rod which lies
centrally within the main or outer rod and is here shewn as also constructed in
three sections or lengths D¹ D'D' to conform to the members A', A', A². These
rod sections are guided in their longitudinal movement and restrained from falling
out of their respective outer rod sections when the outer rod is disjointed, by rivets,
pins, or screws h passing transversely through the outer rod or its ferrules and
through slots in the inner rod sections. The several inner rod sections are
preferably made to centre with each other at their meeting ends, as shewn at k in
Figure 3, and so that they will virtually form a straight continuous rod. The front
section or length D' of this movable rod is hooked on or engages with a transverse
pin or screw applied to the compressing ferrule B and passing through side
slots m m in the cap-like ferrule d on which the compressing ferrule B slides. This
provides for the outward movement of the compressing ferrule to laterally expand
or distend the swab C by projecting the inner rod D', D2, D³, forward and so
producing end compression on the swab which swells it out laterally as shewn by
dotted lines in Figure 2. Such outward movement of the inner rod is effected by
applying force to the back end of the section D³ of said rod, as for instance through
a cam lever E applied to a split strap on the rear member A* of the outer rod
and working at its cam end within a recess n in said member, the cam portion of
the lever bearing against the back end of the rod section D³ and being held there,
and the working parts in place, ready for operation, by a spring G arranged
between a stop collars on the inner rod section D' and a loose collars having a
suitable bearing or stop in the front main member A'.
By means of this device the swab or cleaner may be readily entered within the
gun and be distended or spread laterally by direct pressure applied to it after it
has been put into the gun and be adjusted to give any required pressure against
the sides of the barrel, it only being necessary to apply the requisite force to
the thrust rod to move it forward, while the outer rod is held firmly by the
hand, and this may readily be done by pressing on the handle portion of the
lever E.
.
If required to change the length of the whole device, the middle section of the
outer rod with its contained inner rod section may be disjointed and removed and
another like section of outer and inner rod, of the necessary or changed length, be
substituted therefor.
Any standard gun cleaner as now made can be used when desired on the outer
or main rod without the inner rod direct pressure attachment.
The several ferrules which are fitted on to the ends of the wooden members of
the outer rod may be secured thereon by screw-threads cut on the ends of said
wooden members and the ferrules be made to fit said screw-threads or the ferrules
may be secured to their places by cross-pins or rivets or otherwise.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is-
1. In gun swabbing or cleaning devices the combination of a tubular main outer

page_text: rod adapted to carry the swab or cleaner on its forward end and a longitudinally
movable inner rod adapted by applying force, to independently move the inner rod
forward to produce a direct and independent pressure on the swab or cleaner to
expand or distend it laterally.
2. In gun swabbing or cleaning devices the combination, with a tubular main
outer rod adapted to carry the swab or cleaner on its forward end and an inde-
pendently and longitudinally movable inner rod adapted to produce direct pressure
on the swab or cleaner to expand or distend it laterally, of a hand lever or device
applied to the outer rod and operating to project the inner rod forward and to
control the pressure applied to it, substantially as specified.
3. In gun swabbing or cleaning devices the combination of a tubular main
outer rod constructed in separable jointed sections or lengths and adapted to carry
the swab or cleaner on the forward end of its advance section and an independently
and longitudinally movable inner rod adapted to produce direct pressure on the
swab or cleaner to expand or distend it laterally also constructed in sections or
lengths to correspond with the sections or lengths of the outer rod and independently
carried by the latter, essentially as herein set forth.
4. In gin swabbing or cleaning devices the combination of a tubular main outer
rod constructed in separable jointed sections or lengths and adapted to carry the
swab or cleaner on the forward end of its advance section, an independently and
longitudinally movable inner rod adapted to produce direct pressure on the swab
or cleaner to expand it laterally also constructed, in sections or lengths to correspond
with the sections or lengths of the outer rod and independently carried by the
latter, and means substantially as described for controlling and regulating the
movement and pressure of the inner rod and for holding the working parts in
position essentially as specified.
5. The combination of the tubular main or outer rod constructed in separable
jointed sections or lengths, as described, the laterally slotted cap-like ferrule ‹ on
the outer end of the forward one of said sections adapted to receive a screw for
attachment of the swab or cleaner, the independently and longitudinally movable
inner rod also constructed in sections or lengths to correspond with the sections or
lengths of the outer rod and independently carried by the latter, the sliding com-
pressing ferrule B on the exterior of the cap-like ferrule d connected as by a pin
with the forward inner rod section, the spring G, and the cam lever E, substantially
as and for the purposes herein set forth.
