Be it known that I, CHARLES M. WOOD- MAN, a citizen of the United States, and a resifdent of Chicago, in the county of lCook and State of Illinois, have invented certain new `and useful Improvements in Gun-Cleaners,
i `of which the following is a full, clear, and exand in which the rod when made in sections thereof when in operation.
act description, reference being had to the accompanying drawings and letters of referencemarked thereon.
The object of my invention is to provide a lsimple, cheap, and effective reciprocating device for cleaning gun-barrels and other tubular objects which will rotate while being thrust into the bore, but will not rotate while fbeing withdrawn, in which the plug used in connection therewith will not require clamping devices to hold it in operative position,
for convenience in carrying it about or to adapt it for tubular bodies of 'greater or less `depth will not become separated in the bore This I accomf n plish by the means hereinafter fully described and as particularly pointed ontin the claims. In the drawings, Figure l is a side view of my invention, showing the rod broken in parts and a portion thereof in section. y Figs.
i. y `2 and 3 are perspective views of counterpart clutch-disks. y parts of the plug of said cleaner.
Fig. 4 is a side view of. the Fig. 5 is o longitudinal section of my invention, show- I Ssf l In the drawings, A represents a screwing the rod broken away where it would pass "through the clutches in the plug and with the `cleaning-brush omitted.
i threaded rod generally of a length exceeding the depth of the bore of `a gun-barrel and prefl erably comprising several sections l 2 3, each of which is provided with screw-threaded dowels ct on one end and a correspondinglythreaded socket at the other to join them to their mates. y this rod inserted in the gun-barrel is a brush Attached to the end section of B, and loosely journaled on the reduced cyy f lindrical end portion of the opposite or outer `1` end section is a handle C.
ofa slightly-tapering shell b, of suitable sheet metal, the ends of which are closed by cores c, of wood or other material, which are provided With central openings, through which .the rod can freely pass. The lengths of said cores are such that a chamber eis left between them, in which an independent diskshaped clutch E is placed and plays back and forth. The side of the clutch E facing the inner end of the rod A is provided with one or more radially-arranged serrations f of 0rdinary pitch, and it is provided with a bore g, having a female screw corresponding to that of the rod A. "When said rod Ais pushed inward, these serratious are adapted to engage correspondingly -shaped radially arranged notches h in the non-revoluble counterpart F, which latter consists of a Lflat disk fitting within the bore of the shell b, that is secured to the inner core d of the plug and has a central opening concentric therewith.
In operation the tapered plug is pushed into i the mouth of the gun-barrel until friction thereof against the sides of the bore holds it fast. The rod is thereupon thrust into said barrel and at the outstart carries said clutch into engagement with its counterpart, which being prevented thereby from rotating causes the rod to rotate, while further inward pressure is applied to the loose handle and until the desired limit of the inward movement of said rod is reached. lVhen the rod Ais withdrawn or moved outward by pulling on the loose handle, the initial effect is to disengage the clutch E from its counterpart and bring `its smooth face against the smooth end of the outer core o of the plug, against which it will revolve, while the rod unaffected thereby will without revolving move outward. The cleansing action of the brush, which thus revolves only while advancing into the gunbarrel, is greater than if it revolved when moving in both directions; but aside from this advantage by the removal of the pressure on the plug, which it would be necessary to exert if the rod was revolved during the withdrawal movement thereof, the plug is enabled to retain its position in the mouth of the gun-barrel Without the aid of extraneous clamping devices, which it would not otherwise be able to do. By making said rod A in sections it can be lengthened or shortened to fit any barrel. The threads on the dowels of IOO Athe said sections thereof will not nnscrew.
What I claim as new is- 1. A cleaner for tubular bodies comprising a screw-threaded cleaner-rod, a bushing adapted to frictionally .engage the mouth of the bore of a tubular body, an apertured disk secured in either end of said bushing encircling said rod, an apertured disk having soreW-threadedengagement with said rod and sliding and rotative engagement with said bushing between said end disks and means within the bushing locking said interior disk against rotation only when said rod is moved toward said tubular body.
2. A cleaner for tubular bodies comprising a screw-threaded cleaner-rod, a bushing adapted to frictionally engage the mouth of the bore of a tubular body, an apertured disk encircling said rod secured in the outer end of said bushing, an apertured disk-encircling said rod, secured in the inner end of said bushing, an apertured disk having screwthreaded engagement with said rod and rotative, sliding engagement in said. bushing and means-on said interior disk and inner end disk to lock said interior disk against rotation when said rod is moved toward said tubular body.
3. A cleaner for tubular bodies comprising a screwthreaded cleaner-rod, a bushing adapted to frictionally engage the mouth of the bore of said tubular bodies, an apertured disk encircling said rod secured in the outer end of said bushing, an apertured disk encircling said rod secured in the inner end of said bushing, an apertured disk having screwthreaded engagement with said rod and sliding, and rotary engagement with said bushing and a lug on the face of said interior disk adapted to engage a lng on said inner end disk and lo'ck said interior disk from rotating, when said rod is moved toward said tubular body.
4. A cleaner for tubular bodies comprising a screw-threaded cleaning-rod, an exteriorlytapered bushing adapted to frictionally engage the mouth of the bore of a tubular body, an apertured disk encircling said rod secured in the outer end of said bushing, an apertureddisk encircling said rod secured in the inner end of said bushing, an apertured disk having screw-threaded engagement with said rod and sliding, and rotary engagement with said bushing, and a lug on the face of said interior disk adapted to engage a lug on said inner end disk and lock said interior disk from rotating,v when said rod is moved toward said tubular body.
