BULLET EXTRACTOR non cARTRnJGEs Anthony Andrade, Santa Clara, Calif. Application september 29, 1953, serial No. 382,902;

' 3 Claims. (cl. str-23) The present invention relates to ammunition and perbullets from the` cartridge cases ofsmall arms ammunition.

`It is frequently necessary. with military ammunition, particularly in the 30-06 and 50 calibers to withdraw the bullets from the cartridge cases in order to salvage for re-use the component parts of rejected or damaged ammunition. There are also a large number of rifle and pistol shooters who hand-load their own ammunition, and such hand loading frequently requires the withdrawal of the projectiles either from factory loadedammunition nism. Even a slight misplacement of the bullet gripping means mayrresult in damage either to the bullet or to the neck of the cartridge case.

It is the general broad object of the present invention to provide an improved bullet puller for extracting the bullets from the cartridge cases of assembled ammunition. The invention also contemplates the accurate positioning of a bullet seizing member for axially withdrawing a cartridge case from a bullet mounted therein. The invention also provides an axially adjustable bullet gripping device for mounting on one of a pair of separable members of a bullet pulling machine, the other of said separable elements being provided with means for gripping the rim of the cartridge case.

These and other objects and advantages of the inven- `tion will be brought out more fully in the following description and the accompanying drawings, wherein:

Fig. l is a perspective view of a bullet puller embodying the present invention. Y

Fig. 2 is a longitudinal sectional view through the mechanism shown in Fig. 1, portions of a supporting machine being indicated in broken lines, as is also a cartridge inserted in the device for disassembly.

The illustrated form of the invention comprises a bullet puller A having generally tubular support housing 10, which may be `of steel. The housing has an externally threaded lower portion 11 of reduced diameter. The threaded lower housing portion 11 is screwed into a threaded hole 12 provided therefor in the uppermost member 13 of a supporting mechanism consisting, as far as the present invention is concerned, of the two

separable members

13 and 14. These members `are controlled for separation by mechanism "of a conventional type (not shown) to move them selectively a predetermined distance toward and away from each other in a direction axially of the threaded hole 12 into which the housing 10 is screwed. A lock nut 15 is provided to se- For this reason, it is desirable that the cartridge l UnitedStates Patent@ i `tains more particularly to a device for extracting `the Patented Apr. 1, 1958 cure the housing 10 in axially adjustedV position in the machine member 13.

A pair of undercut cartridge

case gripping members

17, 17 are secured by screws 17a to the machine member 14 in a position to reecive the rim 18 of a cartridge case 19 therein. Thus, when the machine members v13 and 14 are separated, the cartridge casing 19 will be Withdrawn from the bore 30 of the housing 10.

The bore 30is of a size to receive freely therein a cartridge casing 19 (Fig. 2) of the maximum size to be handled by the device A. A ilange 31 of increased diameter is provided around the upper end of the threaded lower housing portion 11, and a pair of

support standards

32, 32 are formed integrally with the threaded lower housing portion 1110 extend vertically upwardly from diametrically opposite sides of the ange 31.

, A tubular upper housing portion 33 is mounted integrally on the

standards

32, 32 with its bore 34 disposed coaxially with that of the threaded lower portion 11. A headed sleeve 37 is iitted telescopically into the top of the upper housing portion 33. The enlarged head 38 of v the sleeve 37 seats upon the upper edge of the cylindrical upper housing portion 33 to prevent downward displacement of the sleeve 37 relative to the housing 10.

The sleeve 37 is secured against rotation in its fully seated position in the housing 10 by a set screw 39. "Ihre .head portion 33 of the sleeve 37 has a hole 40 axially therethrough to journal a chuck control screw 41 therein.. The chuck control screw 41 has an enlarged head portion 42 thereon, and a turning pin 43 is inserted in a hole provided therefor transversely of the axis of the screw 41. The head. portion 42 of the chuck screw 41 is supported onV a washer 44 which preferably is of friction reducing material such as brass or bronze. The washer 44 rests on the head 42 of the sleeve 37.

The threaded chuck control screw'41 is screwed into van-internally threaded upper bore portion 4S provided therefor in a collet type chuck member 47 which is iitted for axial slidable movement into the lower end of the bore 48 of the headed sleeve 37. The lower end of the v chuck 47 is divided by longitudinally extending slits 49 into a plurality of symmetrical iingeriike jaws 50 in a manner customary in the making of collet chucks. The bore 51 of the lower end portion of the chuck 47 is smooth, and is of a size to receive therein a bullet 52 of the size to be removed. The external faces of the four linger-likeljaws 5l) of the collet chuck 47 are of slightly increased diameter at their lower ends S3, as is commonV f in position in the housing 10 by brazing or silver soldering. TheV pin S4 is mounted with its axis disposed radially to the axis of the upper housing portion 33 and extends inwardly from its supporting standard 32 a sui- Vcient distance to extend beneath the collet 37, but not sufliciently to contact a cartridge B positioned with its bullet 52 inserted co-axially in the collet. Y Y

In using the bullet puller A of the presentinvention, a collet. chuckl member 47 is selected'having a desiredV internal diameter toreceive and grip a bulletv 52 of ,the;-

size to be extracted. Thedevice A is mounted by screwing the threaded lower housing portion 11 into the threaded opening 12 in the member 13, as shown in Fig. 2,

When it is necessary to change collet chucks 47, this may be accomplished by unseren/ingl theA set screw 39 to free the headed sleeve 37, removing this sleeve 37 with the chuck t7 and chuck control screw 41 therein, unscrewing the screw d1 to release the chuck d'7; The chuck d'7 then is replaced with another generally similar chuck (not shown) having the required bullet receiving7 bore diameter. The parts are then reassembledr by reversing the above procedure.

The rimV receiving tracks i7, 317 should 1c of a size to receive and overlie the rim i3 of the cartridge to be disassembled. If necessary the

tracks

17, 17 may be removed by unscrewing the screws 17a and replaced with tracks of the proper size and amount of separation such replacement tracks (not shown) may be secured in position by replacing the screws ia, 17a,

For adjusting7 the device preparatory to an actual bullet extracting operation, the collet control screw 41 is unscrewed sutiiciently to free the dared lower end portions 53 of the collet jaw members Sil from the sleeve 37 and thus to permit the chuck 47 to rest on the chuck positioning pin 54. A cartridge B of the size to be disassembled then is inserted in the device A as shown in Fig. 2 with Y the

machine members

13 and 14 in their fully shut or closed position of minimum separation substantially as shown in Fig. 2. The housing 16 is screwed into or out of the machine member 13 as required to bring the cartridge into position where the chuck 47 will grip the bullet 52 as close to the top of the cartridge case 19 as possible but will not nip the neck 19a of the cartridge case. This adjustment is easily observed by looking in between the

standards

32, 32. When the proper adjustment is attained the housing itl is secured in adjusted position by means of the lock nut 15.

The cartridges then may be disassembledrby inserting the rim 18 in the

tracks

17, 17 as shown in Fig. 2 with the

machine members

13 and 14 in their open or separated condition (not shown), the cartridge B axially aligned with the housingbore 3i), and the chuck 47 freed to rest upon the chuck positioning pin Sd.

The machine members 13 and 1d then are moved to their closed position shown in Fig. 2, and the chuck control screw is turned to draw the chuck d'7 into the sleeve 37 to grip the bullet 52. The

machine members

13 and 14 then are separated axially of the cartridge B to withdraw the bullet 52 from the cartridge casing 19 and to withdraw the cartridge casing 19 from the bore 30 of the housing lil. The chuck 47 then is released by unscrewing the chuck control screw el, which permits the bullet to drop through the bore 3G and upon removal of the cartridge casing 19, places the apparatus in condition to repeat the operation.

While l have illustrated and described a preferred ernbodiment of the present invention, it will be understood however, that various changes and modifications may be made in the invention as set forth in the appended claims.
