. amended April 30, 1928; 370 "OLG. 757) The invention described herein may be manufacturcd and used by or for the Government for governmental purposes, withoutthe payment to me of any royalty thereon. V Thisinvention relates to a combination tool for a firearm, more particularly to a tool for cleaning the chamber of the firearm.

Adequate cleaning of the chamber of a firearm is usually a diflicult procedure and is especially true of l firearms having receivers of such shape. as to obstruct free access to the bore. When the,

Referring to Fig. 1, there is: shown in its preof securing the cleaning brush to the combination tool: 1

Fig. .5 is a right end elevational ferred form a. combination tool in assembled rela tion. A handle I is preferably formed from a cylindrical bar. One end of handle I has an inchamber is not readily accessible from the breech I end,'it is necessary to improvise some sort of cleaning implement for scouring the chamber, as a suitably formed offset cleaning rod. For military us such an improvised cleaning toolwould be decidedly inconvenient to carry separately in the field. As it is imperativethat a rifle bore and chamber be kept clean at all times, particularly the chamber, it is highly desirable to carryclean ing implements with the rifle.

arm, access to this recess being made thru a trap door in the butt plate. Occasionally it is desirable to disassemble the entire rifle for a thorough cleaning and infrequently to replace a damaged or defective part. This procedure is facilitated by a screw-driver and a drift pin. A ruptured cartridge case in the chamber is best removed with aspecial extracting tool. If these various tools are carried separately some will undoubtedly be lost or misplaced andhence will not be available when most urgently needed. Therefore a, tool which combines the several tools in one, which can be conveniently carried within the buttstock of the firearm, and is convenient to Accordingly it is an object of this invention to provide a compact combination toolwhich combines implements for cleaning the. chamber of the firearm and for disassembling the firearm. 1 1

A particular object of this invention is to provide a combination toolincorporating therein an extractor removing tool for removal of the extractor from the bolt of a rifle such as disclosed in U. S. Patent No. 1,892,141 to John C. Garand.

The specific nature of the invention as well as other objects and advantages thereof will clearly appear from a description of a preferred embodthe accompanying drawing, in which: 7

Fig. 1 is a top elevational view of a combina- -tion tool shown partially in section.

This is usually accomplished by inserting these implements in. a suitable recess within the butt-stock of the fire- I tegrally formed head Ia. Two fork-like prongs 2a and 2b (Fig. 5) project; upwardly fromthe end of head la. These prongs are for removing the extractor from the bolt of a rifle such as disclosed in the aforementioned U. S. Patent No. A suitable recess. 3 is provided on the head Ia between the prongsia a nd2b to hold an ejector (not shown) in position while .the lower. edge of the face and opposite the prongs 2a and 2b, a narrow milled slot 4 (Fig. 4) is provided. This slot is semi-circular in depth and fits the base ,of a cartridge. The lower side lc of head Ia opposite the prongs 2a and 2b is milled flat and a. semi-circular opening 5 (Fig. 4) smaller in diameter than the slot 4 in order to fit the extractor groove of a cartridge case, is provided from the flat side l-c to the slot 4. Just to the rear of thesurface lc axclear'ance cut 6 is provided in the head la to allow the tool to be inserted within the receiver (not shown) of a rifle similar to that shown in U. S. Patent No. 1,892,- 141toengage and extract a ruptured cartridge case. i 1

Adjacent the head la two flat milled. surfaces 10, and 112 (Fig. 2) diametrically opposed, are

provided on the handle I. These surfaces ar in l the same horizontal plane as the slot 4. A centrally located transverse hole 8 is provided in thehandle I approximately in the center of the surfaces 1a andflb. Arivet 9 inserted. in the hole 8 fastens a blade 10 securely but movably about the axis of the rivet 9 to the handle 6. The blade ID has aflat outwardly projecting boss i 0a which bears against the surface 1b. One end Illa of blade I0 is shaped .toform a conventional screwdriver blade while the other end Illb forms a sion rod l2 has an integrally formed short tubular Fig. 2 is a longitudinal sectional view taken 3 along the central longitudinal axis of Fig. '1. i

Fig. 3 is a cross sectional view taken along the plane 3-3 of Fig. 2 showing a preferred method head I2a projecting outwardly from the handle Two displaced holes 13a and |3b are provided in the rod and are connected by aslot M. A

spring clip I5 slidably surrounds. the handle I.

view taken is brought The clip l has an integral spring arm l5a extending along the handle I, the end of which is slightly upturned. A pin I6 having an integral shoulder Illa is riveted or otherwise secured to the arm Ida and projects downwardly thru a hole I I (Fig. 2) in the handle I into the hole I3a in iii.

the rod I2. A detent I51) provided on-the' clip lily engages a corresponding notch I8 in the handle I after the pin I6 has been inserted in the hole I1 and the clip I5 pushed slightly to the rear .so'

that the smaller diameter of pin I6 engages the rear edge of hole I 1.

Thus when the upturned end of the spring arm I5a is lifted upwardly the I shoulder I6a on pin I6 will bear against the'unto a position where the shoulder IBa is aligned with the hole "in the handle I. -A suitable cleaning brush I9 is movably secured to the end I2a' of the rod Izby apin 20 which is inserted in suitable holes 2| and 22 in. the end I2a and thru the hole I9a of the brush I9. is secured to the end IZa by the ring spring 23 The pin 20 which surrounds the member I200. The spring 23 l is secured to the pin by any suitable means,

as by riveting. The hole I9a thru the end I!!!) of brush I9 is cone shaped at each end to permit angular motion of the brush I9. While the brush I9 is preferably attached to the U-shaped member in the manner shown, the brush may be attached to this member by any suitable conventional toggle or universal joint means.

To use the combination tool for cleaning the chamber of a rifle the extension rod I 2 is first extended by lifting the pin I6 out of the hole I3o by raising the spring I5a and withdrawing rod l2 from the holeIIuntil the pin It strikes a shoulder I on rod I2 at the rear o'fhole I3b'. The pin I6 is then allowed to enter the hole I3b thereby locking the rod I2 to the handle I. With the tool thus extended the brush I9 is readily inserted into the cleared chamber of a firearm.

As the brush I is attached to the handle I by a toggle joint the handle'can be bent at a considerable angle to clear any obstructing portion of the receiver. For the best scouring action the handle should be revolved, such revolving motion being imparted to the brush by the toggle joint even though the handle may not be parallel to the chamber. The tool is most conveniently rotated when the blade It! is pivoted to a transverse position with respect to the body of the tool. The blade II) in such position facilitates grasping of the. tool and permits a ready application of a revolving motion.

A ruptured cartridge case'may be iextracted from the chamber after the bolt is withdrawn vby holding the tool in ;a vertical-position and sliding the head Ia of the tool over the head of a cartridge (not shown) so that the slot 4 engages the rim of the cartridge. Using the bridge of a receiver (not shown) as a fulcrum and the handle I as a lever the ruptured case is readily removed when pressure is exerted against the handle. The screwdriver Illa and drift pin IlJb may be used in a conventional manner, the handle I also serving as a handle for the screwdriver when the blade I0 is turned at an angle to the handle, about the pin-'9. f I

The extension rod I2 of this tool is provided to give extra length to the tool so that when used "for cleaning the chamber of a rifle the handle I will project beyond the breech mechanism (not shown), thereby eliminating the danger of injury to the user by keeping the hand away from contact with any metal projections of the breech.

The combination tool is however conveniently carried within a suitable recess in the buttstock of a rifle (not shown) when the rod I2 is in the fully inserted position as shown in Fig. 2 and the blade I0 isturned parallel to the handle. I. Thus the tool becomes a compact combination of useful cleaning and disassembly implements which are not easily lost and which may be carried with the rifle with no inconvenience and be'ready' fo'r use at all times.
