SPECIFZLIATION forming part of Letters Patent No. 659,928, dated October 16,1900.

Application filed luly 30, 1900.

To all. 1171 0711 it may concern:

Be it known that I, THOMASC. JOHNSON, of New Haven, .in the county of New Haven and State of Connecticut, have invented a new Improvement in Ejector-s for Breecl1-Loading Firearms and I do hereby decla re the following, when taken in connection with the accompanying drawings and the letters of ref erence marked thereon, to be a full, clear, and i0 exactdescription of the same,and which said drawings constitute part of this specification, and represent, in-

Figure l, a broken view, in side elevation, of a gun provided with myimproved ejector; Fig. 2, a broken plan view of the gun, partly in horizontal section, showing the springejectorin its normal position: Fig. 3, ahroizen view of the gun in-horizontal section, showing the ejector-spring as placed under tension by the engagement with it of a cartridge at the time the same reaches the limit of its rearward excursion with the breech-bolt; Fig. at, a b'rolen view, in inside elevation, of the left-hand wall of thereceiver of the gun, showing the breech-bolt of the gun, one of the extractors carried thereby, and the abutmenthead and the ejectorspring of my improved ejector. Figs. 5, 6, and 7 are sectional views showing modified forms which my invention may assume.

My invention relates to an improvement in ejectors for breech-loading firearms, the ob ject being to prodncean ejector of superior simplicity and effectiveness of construction, composedof few parts, and not liable to derangement.

With this end in View my invention consists in an ejector having certain details of construct on, as ll be hereinafter described, and pointed out in the claims.

In carrying out my invention, as shown in Figs. 1 to l, inclusive, of the drawings, I employ an ejector-spring 2, consisting of a flat piece of 'resil icnt metal tapering from its outer to its inner end and bent about midway of itslength, 5L that its inner end stands at a slightly-acute angle to its outer end, which is perforated for the passage of a screw 3, by means of which the spring is fastened to the out-er face of the left-hand wall of the gun frame or receiver 4, which is formed with a Serial No, 25,220. (No model.)

transverse'opening 5, throught which the bent inner end of the spring extends, soas to project for a short distance into the receiverchamber 6 of the gun. Directly to the rear of the projecting inner end of the said spring ilocatea small abutment-head 7, formed upon the inner end of a pin or stem 8, which enters the inner end oi a small transverse hole!) provided for it in the left-hand wail of the gun-frame at a point directly to the rear of' the opening 5 before mentioned. The said spring and abutment-head are located so that just before the breech-bolt 10 reaches the limit of its rearward excursion the rear face of the flanged head 11 of the cartridge 1 2 will engage with the projecting inner end of the spring 2, whereby the same wiili be'pi'aceif under tension and bent backward into ongagement with the head 7, as shown in Fig. 3, the cartridge being drawn backward out of the gun-barrel by means of extractors 1'3 13, carried by the breech-bolt 10 and oi any approved construction. The shock of stopping the rearward excursion of the bolt does not fall upon the spring, which, if it did, would be broken, but upon the abutment-head 7. hen this shock has spent itself, the bent inner end of the spring recovers 'aud'in covering ejects the shell from left. to right out of the gun; The yielding inner end of the spring, it will be observed, stands at'substantially a right angle to thev path'of the cartridge. It will be seen from the foregoing'that my improved ejector, consisting, as it does, of' the spring 2 and abutment-head v7, is extremely simple to construct and apply, and that as it comprisesonly two parts it is. not liable to derangement. It is, moreover, very eifective. In the modified construction shown by Fig. 5 the ejector-spring 14 is secured in place by having its outer end perforated for the pee-- sage through it of the stem 15 of the abutment-head 16, which holds the said end of the o I spring against the inner face of the left-hand Wall 17 of the gun-frame, which-is formed at a point directly ahead oi the stem 15 with a transverse opening 18, receiving the resilient or yielding end of the spring, which stands at a right angle to the path ofthecartridgeshell and projects into the receiver-chamomsame is drawn backward in being extracted.

The end of the spring is forced backward upon the abutment-head 16 and in recovering ejects the cartridge from left to right.

In the modified construction shown by Fig.

6 the loop-shaped ejector-spring 19 is secured by a pin 20 in a shallow recess 21, formed in outer face of the left-hand wall 23 of the gunframe by means of a screw 24:, which passes through the forward end of the block into the frame. The said spring 19 projects forward from the recess 21 into a transverse passage 25, formed in the gun-frame 23 at a point directly forward of a hole 26, formed in the frame for the reception of the stem 27 of the abntmentfhead 28, which is-located directly to the rear of the longer inwardly-projecting forward end of the spring 19, the shorterrear end of which bears upon the rear wall of the recess 25. The stem 26 aforesaid enters the rear end of the block 22 and prevents the same from turning upon the screw 24 as upon a swivel. In this construction the forward end of the spring 19 is engaged by the lefth'and edge of the head of the cartridge-shell and forced rear-ward into engagement with the abutment 28, after which the spring recovers and ejects the shell.

In the modified construction shown in Fig. 7,-the ejector-spring 29 consists of a leaf, term'inating at its outer end in a rib 32, which received in a transverse hole 31, formed in ,the inner'face of a block 30, secured by means of a screw 83 to the left-hand wall 34 of the gun-frame, the screw 33 passing through the forward end of the block 30, which is prevented from turning upon the screw as upon a swivel by the entrance into its rear end of combination with the gun-frame, of a breechthe stem 35 of the abutment-head 36, which is located directly to the rear of the in wardlyprojecting end of the spring, which is free to be moved back and forth in a horizontal plane in a passage 37, formed in the gun-frame at a point directly in front of the hole 38, formed for the reception of the stem 35. The spring 29 is prevented from turning upon the rib 82 by the confinement of the extreme outer end of the spring between the walls of a slot 39, opening out of the hole 31, formed in the block 30. This spring 29 is placed under tension by the cartridge-shell j ust before the same reaches the limit of its rearward excursion, the end of the springbeing then forced against the abutment-head 36, after which the spring is allowed to recover and eject the cartridge.

It will be observed that in the form of my invention shown in Figs. 1 to 4, inclusive, and in the modified forms shown by Figs. 5 to 7, inclusive, the ejector-spring in every case is the inner face of a block' 22, secured to the 1 that I do not limit myself to the constructions connected with the left-hand wall of the gunframe and arranged to stand at or substantially at a right angle to the path in which the cartridge-shells are extracted. All of these springs are brought to bear upon the abutment-head which the shell is brought up against when it reaches the limit of its rearward excursion, and all of these springs when they recover eject the cartridges from left to right. I would therefore have it understood herein shown and described, but hold myself at liberty to make such changes in and alterations from the same as fairly fail within the spirit andscope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1., The combination with a gun-frame, of an ejector-spring fixed thereto and standing at; a right angle to the path in which the cartridge-shell is extracted, and in position to be engaged and placed under tension by the said shell which it ejectsin its recovery,a nd means located to the rear of the spring for limiting the rearward excursion of the cartridge,

and preventing the excessive bending of the spring.

2. The combination with a gun-frame, of an ejector-spring secured to the gun-frame and having'one end passed through an opening formed in the gunfframe into position to be engaged by the head of acartridge-shell when the same is being extracted from the gunbarrel, and a fixed abutment-head located di- 'rectly to the rearof the projecting end of the said spring which is forced against the head when the gun is opened and the cartridge extracted', but which recovers to eject the, cartridge.

3. In a breech-loading magazine-gun, the
