Application led July 29, 1915.

To @ZZ who/m t muy Concern.'

Be it lrnown that we, @aan Swnernius and "flans T. R. rianirz, a citizen of the United States of America and a subject of the Emperor of Germany, respectively, both residing at N ew Haven, if ew Haven county, Connecticut, have invented a new and useful Firearm, of which the following is a speciiication.

Our invention relates to firearms, and particularly to rifles of the single shot variety.

rllhe invention consists in a new and useful cartridge extracting and ejecting means which is designed to reliably and effectively dislodge and eject an empty shell from the chamber of the barrel.

ln the drawings: Figure 1 is a side elevation, partly in section, of the middle or breech portion of a irearin equipped with our invention. Fig. 2 is a similar view showing the parts in a dirlerentjiosition. Fig. 3 is also a similar view showing the parts in still another position. Fig. 4l is a section on the line 4--4f of Fig. 1. Fig. 5 is a front elevation of certain parts detached. Figs. 6, 7 and 8 are perspective views of details.

1 represents the receiver, 2 the' stock, 3 the barrel, e the breechbloclr, 5 the breechbloclr operating lever, 6 the hammer pivoted to and carried by the breechblock 4, and 7 the trigger, likewise pivoted to and carried by the breech block. rlhe lever 5 is pivoted to the underside of the receiver frame 1 on the pvot pin 8. 9 is an extension at the pivoted end of the lever which is connected to the breech block through the medium of a link 10.

l1 is the usual firing pin carried by the breechbloclt for operation by the hammer 6.

12 is al pin carried by the frame and upon which the rear end of the breechblock 4e is mounted to slide and partially turn as said breechblock is moved up and down. The rear end of the breechbloclr may be slotted as shown, to receive the pin 12.

13 is a locking shoulder or abutment on the receiver against which a shoulder 14 on the breech block may abut when the breech bloclt is locked up, and the gun is ready for firing, as shown in Fig. 1, in which position, said breechbloclr will be solidly held between said abutment, the rear end of the barrel, and the lever pivot 8.

prises an upright arm 15 which is pivotally supported at its lower end, for example on the pinV 8, the upper end of the arm 15 carrying a lateral offset 16 which directly engages the rim of the cartridge as it stands in the barrel, so that when the arm 15 is swung back, the cartridge will be extracted and ejected. This extractor is located in a recess or space between the side wall of the breech block and the adjacent side wall of the receiver. At the forward edge of the arm 15, and toward the lower end thereof is a projection 17 which provides two opposite inclines, as shown, which are designed to cooperate with a spring plunger 18 which is mounted in the front end of the receiver, and is pressed by a spring 19 in a direction to cause the plunger 18 to yieldingly bear against one side or the other of the projection 17. 2O is a projection at the opposite edge of the arin 15 from the projection 17. One edge of this projection 2() is partially beveled, as indicated at Q1. rlhis projection 2O coacts with another spring plunger 22a-rr nged to project from the side of the breech block it. The projecting end of the spring plunger 22 is likewise partially beveled on that side which faces the incline A 21 on the extractor. 23 is a lug on the side of the upper part of the breech block 4E which is also designed to cooperate with the eX- tractor in the manner and for the purpose described hereafter.

Gperation: Let it be assumed that the V parts stand in the position shown in Fig. 1, wherein the gun is locked up ready for firing. When the hammer has dropped and the gun has been red, the operator may swing the lever 5 downwardly so as to lower the breech block. When the breech block has been lowered to a suiiicient extent to clear the empty shell in the chamber of the barrel,-that position being approximately indicated in Fig. 2,-the plunger 22 will encounter the end of the projection 20 on the extractor, so that the further descent of the breech block will cause the extractor to tilt baclwardly on its pivot 8, thus extracting the'shell. This iirst partial movement of the extracto-r is comparatively slow. llmien, however, the extractor has tilted sufficiently to cause the point 17 to clear the point 18a of the plunger 18, the spring 19 will cause the plunger 18 to jump ahead quickly so as indicated the several views.

to impart a ver f quick backward throw to the extractor, thus guaranteeing the certain ejection ofthe empty shell. rlhe extreme rearward movement or position of vthe extractor is indicated in dotted lines, lig` 2. The continued forward swinging movement of the lever 5 from the position indicated in Fig. 2 to that indicated in Fig. 3 imparts,

in effect, adownward and forward move-V ment to the upper end of the breech block,

whereby the lng 28 on the latter engagesV cated in 3 to that indicated in 1,

thus completing a cycle of operations. Y

The efiect of the plunger 18 against the opposite inclines ofthe projection 17 is to hasten the last part of the rearward movement of the extractor for the above purpose, and to also hasten the last'part of the forward movement thereof-so as to guarantee' the seating of the offset end 16 in Vits inactive position.

Vfhat we claim is:

1. ln a single shot firearm, a receiver, a

barrel having a cartridge chamber Aat .its
