,JENS THEODOR SUHR sonohison; or HOLTE, DENMARK. MECHANISM FOR EXTRACTIVNG AND ntcrme SPENT CARTRIDGE-CASES m Bacon-Guns. I

' Be it knownthat I,\JEN S THEoDoR' SUH So1-ioUBoE,- a subject of the King of Denmark,

residing at Holte, Denmark, have. invented new and useful Improvements in Mechanism for Extracting and Ejecting Spent Oartridge-Gases in Recoil-Guns and the Like, of

which the following is a specification.

' The invention relates-to improvements in mechanism for extracting and ejecting cartridge-shells in recoil-guns and the like.

The improved ejectingmechanism comprises three principal elements-'an ejector," a restoring-lever therefor. carried by aco'nvenientrecoili'ng part ofthe gun,'and a station- I ary cam-block, with which the said restoring.-

spent shell.

' The invention is illustrated in the-accom pan ing drawings, applied to an automatic lever and ejector. cooperate :in ejecting the loa er provided with a recoiling barrel, the

restoring-lever and ejector being connected with the barrel in a manner to participate in the recoil movement-thereof and the camblock being so disposed with res ect to said restoring-lever and ejector that t e latter are thrown into. relative positions in a manner to engage and eject the spent shelL- I In the drawings, Figure 1 is a vertical section of the breech end of a gun, showing the ejecting mechanism and its cooperating parts in the osition assumed-when the n is loaded an ready to be fired. Fig. 2 1s a similar view showing the position the parts assume during recoil,. the shell beingpartiallyejected. Fig. 3 is a similar view showing an extreme position of the parts, the shell being removed .and the parts being in position to receive a new. cartridge. Fig. 4 is a plan and side elevation-of the ejector-restoring lever. Fig. 5. shows side and edge.

; gviews of the ejector. Fig. 6 is a horizontal .section of the breech-casing, showing the cam-blocks with which the restoring-lever v the cartridge, the lengthof the slot 7 providing for the required u ward movement of the ejector to efiect suc engagement. At the bottom the said ejector has aprojection 10,

adapted to be engaged and depressed by the restoring-lever 2. 7

The lever 2 is pivotally. mounted upon a pin 11, which, like the pin 8, is secured upon the projection 3. At its'forward end the lever 2 is provided with a projection or nose 12 and atits rear with the projection 13, adapted to engage and depress the projection 10, said engagement being effected by the spring 14, interposed between the lever 2 and the barrel. the lever 2 tends to swing the ejector 1 into the position shown in Fig. 1. In this, the firing position, the action of the spring 14 is reinforced by engagement of the nose 12 with the end wall of the casing 4, which latter engagement would in case the spring 14 became displaced or injured serve to insure the restoration of the ejector to the position shown in Fig. 1. eral projecting pin 15, adapted for engagement with the cam-block, which latter is preferably formedintwo pieces 5 and 6, having cam-surfaces disposed in horizontal and inclined planes. The block-'5 is recessed between the horizontal portions of the rear wall forming an; abutment 19. When the gun is fired, the breech-block and the barrel recoil and the ejector 1 and lever 2 are carried rearwardly. The lower edge 18 of the ejector 1 engages the inclined surface 16 of the block 5, sliding upwardly thereon, forcing the hook 9 into the groove of the cartridge, the ejector remaining in a vertical position until the pin 15 of the lever 2 strikes'the inclined face 17 of the block 6. The projection 10 being freed from pressure of the projection 13, the edge 18 engages the abutment 19 and the ejector is swung rearwardly around the pivot by the continued recoil movement and spent cartridges ejected. It will be uriderstood that simultaneously with the rear movement of the ejector there will be a corresponding upward movement of the breech-block to permit the cartridge to be withdrawn. After the shell is ejected the breech-block again moves downwardly to the position shown in Fig. 3 and, cooperating with the restoring-lever, prevents the ejector from being swung into an upright position until a new cartridge is inserted. Durin the advance movement the breechbloc moves upwardly, closing the cartridge-chamber, and the lever2 and ejector 1, respectively, are released from the cam-blocks, the ejector actuated by the lever 2, the latter influenced by Under the influence of this spring The lever 2 carries a latthe spring 14, advancing to the initial posi'-.

Having now partic arly described and ascertained the nature of my said invention and in what manner the same is to be performed,- I declare that what I claim is 1. A cartridgeej ector for recoil-guns comprising in combination a recoil element, an

ejector movabl mounted thereon, a restoring-lever mova ly mounted on said element, and normally engaging the ejector to hold it in a position to engage the shell, and means 0 lrlating said ejector and lever to eject the s e I 2. A cartridge-ejector for recoil-guns comprising in combination a'recoil element, an ejector movably mounted thereon, a restoring-lever movably mounted on said element, a ring efi'ecting engagement of said lever anii the ejector and holding the latter in a position to engage the shell, and means operating the ejector and levr to discharge the ejector movabl shell.

3. A cartridge-ejector for recoil-guns comprising in combination a recoil element, an

mounted thereon, a restoring-lever mova I mounted on-said element, said levernorma ly engaging the ejector and holding it in a position to engage the shell, and a cam-block having inclined horizontal and abutting surfaces for engagement with said e'ector and lever. 4. cartridge-ejector for recoil-guns comprising in combination a recoil element, an ejector movabl mounted thereon, a restoring-lever mova ly mounted on said element, a spring efi'ecting engagement of said lever and ejector and holding the latter' in a position to engage the shell, and an e'ector-block havingino'lined horizontal and a utting surfaces for engagement with said ejector and lever.

5. A cartridge-ejector for recoil guns comprising in combination a recoil element, an ejector loosely pivoted thereon, a restoringlever pivotal y mounted thereon, a spring effecting engagement of the lever and ejector to hold the latter in a position to enga e the shell, and a cam-block provided wit inclined and horizontal portions and an abutting portion for engagement with said ejector and separate inclined and horizontal portions for engagement with said lever.

6. A cartridge-ejector for recoil-guns comprising in combination a recoil element, an ejector and -.a restoring element normally in coacting relation and carried by said recoil element, and means throwing said ejector
