PROVISIONAL SPECIFICATION.
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
declare the nature of this invention to be as follows:-
:
My invention relates to improvements in gun swabs or cleaners and has for its
object to provide a simple, durable, and economic cleaner the body of which consists
of an effective reticulated cleaning material supported internally and expanded by
an elastic cushion having equal bearing over all the surface of the said cleaning
material. Another object of the invention is to provide means whereby the cleaner
may be expeditiously and conveniently adjusted to the bore of any gun barrel it
may be desired to clean. Another object of the invention is to construct the device
in such a manner that the entire cleaning portion of the body will act at one time
upon the interior of the barrel, thus ensuring an expeditious and effective cleansing
of the interior of the latter.
The body of the cleaner consists of a cylindrical cushion made from rubber or a
like material and a wire gauze envelope stretched over and secured in such
manner as to completely cover the outer surface of the elastic cushion, the gauze
being applied to the cushion in such a manner as to render it closely and smoothly
fitting. The gauze is made, to extend over and around both ends of the elastic
body cushion which has a central longitudinal bore to receive a stem, the stem
having formed thereon at one end a disc-like head having a concaved under
face whilst on the other end of the stem is slipped a similar concaved disc-like
head, the end portions of the gauze envelope being turned in or wrapped over
the ends of the elastic cushion and securely clamped between the same and the
concave faces of the two discs or heads. The loose head slides only on the stem,
being prevented from turning by a set screw engaging in a longitudinal groove
in the stem which is screw-threaded at this part to receive an adjusting nut
whereby the end pressure of the discs may be varied to compress and expand
more or less the elastic body cushion to suit the bore of the gun. This nut is
preferably circular and milled or roughened in any suitable manner.
For use, the threaded end of the stem may be screwed on to the end of a rod
or handle and when the cleaner is inserted in the gun barrel the gauze envelope
of the body will act uniformly throughout its entire outer face upon the wall of
the gun barrel and therefore clear everything before it and, further, the gauze
being provided with the rubber or elastic cushion bearing upon it equally
throughout, whenever any one portion of the gauze is depressed, as by the rifling
of a barrel for instance, when that portion of the gauze is carried over the rib
producing the rifling it will accommodate itself to the channels between the ribs of
the barrel. Thus this swab may be employed as effectively in the cleaning of rifle
barrels as in the cleaning of barrels having a smooth bore.
A modification of the cleaner consists simply in employing, instead of the gauze
covering or envelope on the entire surface of the elastic cushion, ribs produced
on the outer surface of the cushion and secured thereto in any suitable manner,
these ribs consisting preferably of one or more strands of wire, and when more than
one strand is employed the strands constituting each rib are twisted together.
Dated this 2nd day of March 1892.

COMPLETE SPECIFICATION.
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
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:-
My invention relates to improvements in gun swabs or cleaners and has for its
object to provide a simple durable and economic cleaner, the body of which consists
of an effective reticulated cleaning material supported internally and expanded by
an elastic cushion having equal bearing over all the surface of the said cleaning
material. Another object of the invention is to provide means whereby the cleaner
may be expeditiously and conveniently adjusted to the bore of any gun barrel it
may be desired to clean. Another object of the invention is to construct the device
in such a manner that the entire cleaning portion of the body will act at one time
upon the interior of the barrel, thus ensuring an expeditious and effective cleansing
of the interior of the latter.
i.
1.
The invention consists in the novel construction and combination of the several
parts as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming
Specification in which similar figures of reference indicate corresponding parts in
all the views.
Figure 1 is a side elevation of the improved device.
Figure 2 is a central vertical section through the device.
Figure 3 is a slightly modified form of the cleaner or swab.
Figure 4 is a central vertical section through the modification, and
a part of this
Figure 5 is a transverse section, taken practically on the line 5-5 of Figure 4.
The body of the cleaner consists of a cylindrical cushion 10 made from rubber or a
like material and a wire gauze envelope 11 stretched over and secured in such
manner as to completely cover the outer surface of the elastic cushion, the gauze
being applied to the cushion in such a manner as to render it closely and smoothly
fitting. The gauze envelope 11 is made to extend over and around both ends of the
elastic body cushion 10 which has a central longitudinal bore 12 to receive a stem 13,
the stem having formed thereou at one end a disc-like head 15 having a concaved
under face and the upper end portion of the gauze covering 11 of the body is
clamped and retained between the upper end of the elastic cushion 10 and the head
of the stem. Upon the lower threaded end 14 of the stem is loosely slipped a
socket sleeve 16 provided at its upper end with a disc-like flange 164, the upper
surface of which from the bore or opening of the sleeve is concaved out to the
periphery of the flange and the flange of this sleeve is adapted to clamp and retain
the lower end portion of the gauze cover or envelope 11 between said disc and the
lower end of the elastic body cushion 10. The sleeve is free to slide upon the
stem 13 and is prevented from turning by a set screw 17 passed through the body of the
sleeve into a longitudinal channel 18 in the stem, as shewn in Figure 2. Upon the
threaded end of the sleeve an adjusting nut 19 is placed. This nut is preferably
made circular and its peripheral surface is milled or roughened in any suitable
manner as illustrated at 20 in Figures 1 and 3. When milled preferably the
milling is made in two directions and appears in the form of two belts, but instead
"of the milling, offsets of a beaded character may be produced upon the periphery of
the nut and the peripheral surface of the head 15 of the stem 13 is likewise
roughened so that in the manipulation of the device the head may be firmly held in
the hand and the nut conveniently and expeditiously manipulated to force the
sleeve 16 in direction of or away from the head 15 of the stem according as it may
be desired to increase or to decrease the diameter of the body to fit snugly into gun
barrels of differing diameters."

page_text: It is obvious that the adjustment of this device may be expeditiously and
conveniently effected and that when it is inserted in a gun barrel being used in.
connection with any approved form of rod or staff the gauze envelope of the body
will act uniformly throughout its entire outer face upon the wall of the gun barrel
and as the swab is manipulated in the barrel will therefore clear everything before
it and further the gauze being provided with the rubber or elastic cushion 10 bear--
ing upon it equally throughout whenever any one portion of the gauze is depressed,
as by the rifling of a barrel for instance, when that portion of the gauze is carried
over the rib producing the rifling it will accommodate itself to the channels between
the ribs of the barrel. Thus this swab may be employed as effectively in the
cleaning of rifle barrels as in the cleaning of barrels having a smooth bore.
In Figures 3 and 4 I have illustrated a modification in the form of swab. This-
modification consists simply in employing instead of the gauze covering on the entire-
surface of the cushion 10, ribs 21 produced on the outer surface of the cushion and
secured thereto in any suitable manner, these ribs preferably consisting of one or
more strands of wire and when more than one strand is employed the strands
constituting each rib are twisted together.
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. As an improved article of manufacture a gun swab or cleaner consisting of a
body comprising an elastic core and a cleaning material attached to the outer surface
of the core, a stem passed through the core provided with a head clamping the
upper portion thereof carrying a sleeve engaging with the lower portion of the core
and also carrying an adjusting nut whereby the sleeve may be forced in direction of
or away from the head to increase or diminish the diameter of the body, as and for
the purpose specified.
2. A gun swab or cleaner consisting of a body comprising a rubber core or cushion
and a reticulated cover engaging with the outer surface of the core or cushion, a
stem projected through the core or cushion provided with a head in firm engagement
with the upper portion of the body and having a threaded lower end extending
beyond the lower portion of the body, a sleeve mounted to turn upon the lower end
of the stem and engaging with the lower end of the body, and a lock or adjusting
nut screwed upon the lower portion of the stem the said lock or adjusting nut
acting to maintain the sleeve and likewise the head of the stem in positive yet
removable engagement with the body, as and for the purpose specified.
3. A gun swab or cleaner consisting of a body comprising a rubber core or cushion
of cylindrical form and a reticulated covering closely adhering and conforming to.
the exterior of the core or cushion, a stem projected downward through the core or
cushion provided with a disc-like head concaved upon its under face and engaging
firmly with the upper end of the body, the lower end of the stem being carried
beyond the lower portion of the body and threaded, a sleeve provided with an upper
flange and loosely mounted upon the projecting portion of the stem the flange being
concave in its upper face and in firm engagement with the lower portion of the body,.
a set screw passed through the sleeve into a slot in the stem whereby the sleeve is
prevented from turning and an adjusting or lock nut of disc-like form screwed upon
the lower end of the stem to an engagement with the sleeve, the peripheral surface
of the head of the stem and likewise the peripheral surface of the lock or adjusting
nut being serrated or otherwise roughened, as and for the purpose specified.
