GUN CLEANER Filed April 11, 1923 I g.. I ln/ventola L. If. a/'Zzhy lamented Een, Si), 193@ LOUIS H. DARLING, F VALLEJO, CALIFORNIA GUN CLEANER Application filed April 11,

The invention provides a device for cleaning the barrels of small guns and firearms which is effect-ive in operation in removing ruft, lead, carbon and other matter tending to foul the gun, said device being adjustable and adapted to have the cleaning element readily replaced or inverted, as required, to meet existing conditions.

@ther objects and advantages will be apl@ parent and suggest themselves as the nature of the invention is understood.

Vilhile the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions .nd requirements, various changes in the form, proportion and minor details of construction may be resorted to Without departing from the nature of the invention.

Referring to the accompanying drawings 29 forming a part of the application:

Figure 1 is a side view of a gun cleaner embodying the invention,

Figure 2 is a central longitudinal section thereof, the stem being in full lines,

Figure 3 is a sectional view on the line 3 3 of Figure 2, looking to the left, as indicated by the arrows, the blades being omitted.

Figure 4 is a sectional view on the line tt of Figure 2, looking to the right asdesignated by the arrows, the blades being omitted, and

Figure 5 is a detail perspective view of two of the cleaner blades.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by lik reference characters.

The numeral 1 designates a stem which consists ot a rod having opposite end portions 13 and 14 screw threaded for a short distance. A collar 2 is provided at one end of the stem 1 and is preferably of polygonal form. A retainer 3 cooperates with the collar 2 and is mounted on the threaded end 13 of the stem. A swab 15 is mounted upon the threaded end 13 of the stem 1 and is confined between the retainer 3 and a nut 16. The swab et may be of any suitable material or construction adaptedfor the required work. A slide loose uponv the opposite threaded end of the .item 1 comprises a band 7 and an inner 'TTI 1929. Serial N0. 354,361.

polygonal boss 8. The faces of the boss 8 are lat and receive the flat ends 1() of the cleaner elements 11 which are conlined by the band 7; vA stout helical spring 17 is mounted on the stem, between the slide and a nut 18 on the threaded end 14 and yieldably holds the said slide pressed inwardly to confine the cleaner elements 11 between the retainer 3 and slide. The spring 17Vis expansible and its tension is regulated by the nut 18.

The cleaner elements 11 consist of narrow blades of spring metal, outwardly bowed between their flat ends 10 and having the latter secured in the manner stated. The cleaner blades 11 are transversely corrugated as indicated at 12, whereby to provide scraper elements for positively removing the matter adheringto the wall of the gun barrel. The collar 2 and retainer 3 occupy a liXed position, whereas the slide is adjustable longitudinally on the stem 1 whereby to regulate the curvature and bulge of the cleaner blades. The

' blades have a helical or spiral arrangement to insure contact of the scraping elements 12 with every part of the inner wall of the barrel of the gun to thoroughly clean the same.

1n practice, a rod (not shown) may be applied to either threaded end of the stem 1 so as to reciprocate the cleaner in the barrel of the gun. A transverse opening 19 may be provided in an end of the stem 1 to receive a cord or wire (not shown), whereby the clean er maybe drawn through the gun barrel when cleaning the same.

l/hat is claimed is:

1. A gun cleaner comprising a stem, cleaner elements arranged lengthwise of the stem and grouped about the same, said cleaner elements being outwardly curved intermediate their ends, and confining means on the stem engaging opposite ends of the cleaner elements, one of said means being resilient and adjustable to admit of regulating the bulge or' the cleaner elements.

2. A gun cleaner comprising a stem, longif tudinally disposed cleaner elements grouped about the stein and outwardly curved intermediate their ends, conning means on the stem engaging opposite ends or' the cleaner elements, one of said means including an lOfl expansible spring, and a set nut threaded on the stem to adjust the tension of said spring to regulate the bulge of the cleaning elements.

3. A gun cleaner comprising a stern, a collar at one end of the stem, a retainer associated with said collar, a slide loose upon the opposite end portion of the stem, outwardly bowed cleaner elements confined between said retainer and slide, said cleaner elements being transversely corrugated 'from end to end, and a set nut threaded on the stem for regulatin the bulge of the cleaner elements.

4. A gun cleaner comprising a stem having opposite end portions screw threaded, a retainer at one end ofthe stein, a slide upon the opposite end of the stein, spring means engaging the slide, outwardly curved cleaner blades disposed helica'lly about the stem and confined between said retainer and slide and having transverse eorrugations, and a set nut for adjusting' the tension of said means and for regulating the bulge of the cleaner blades.

5. A gun cleaner comprising a stem, longitudinally disposed cleaner elements grouped about the stem and outwardly curved intermediate their ends, conlining means on the stem engaging opposite ends of the cleaner elements, one of said means being loose, a helical spring on the stem, and a set nut threaded on the stem for Varying the tension of said helical spring whereby to adjust the loose confining element to regulate the bulge of the cleaning elements.

6. A gun cleaner comprising a stem7 a collar at one end of the stem, a retainer associated with said collar, a slide loose upon the opposite end portion of the stem, outwardly bowed cleaner elements confined between said retainer and slide, a helical spring on the stem, and ay set nut threaded on the stem for regulating the tension of said helical spring and the bulge of the cleaner elements.

7 A. gun cleaner comprising a stem having opposite end portions screw threaded, a retainer at one end of the stem, a swab on the end of the stem adjacent said retainer, a slide upon the opposite end of the stem, outwardly curved cleaner blades confined between said retainer and slide and having transverse corrugations, a helical spring on the threaded end of the stem adjacent the slide, and a set nut for regulating the tension of' the spring and the bulge of the cleaner blades.

In testimony whereof I aiiiX my signature.

LOUIS I-I. DARLING.
