FIREARM.

Specification of Letters Patent.

Patented Apr. 16, i912.

Application led May 5, 1910. Serial No. 559,546.

To all whom it may concern:

Be it known that I, JOHN Ql). PEDERSEN, a citizen of the United States, residing at Jackson, county of Uinta, and State of Vyoming, have invented certain new and useful Improvements in Firearms, of which the following is av full, clear, and exact description.

The object of my present invention is to improve in certain particulars upon the fire arms such as are described, for example, in Letters Patent granted to me on January 5th, 1909, No. 908,883; the particular points to which my present invention is directed being toprovide means in a magazine tire arm for raising the rear en d of Athe rear cartridge in the magazine at the initiation of the feeding operation and immediately thereafter interposing means to positively stop the second cartridge from partaking of the extreme rearward movement of the action bar; further. to provide means whereby the rear cartridge shall be held in substantially perfect alinement in the magazine during the operation of charging the magazine: to hold down the bullet end of the rear cartridge while its rim is being raised at the initiation of thefeeding operation, so that the cartridge will be presented in proper alinement to the breech-block: a further object of my invention is to provide means that will insure the proper return of a cartridge to the magazine in the event that the cartridge :trading operation is so incomplete that the cartridge is not delivered to the breech-block and thence to the barrel of the re arm; other objects will appear in the following explanation.

In the annexed drawings-Figure l is a longitudinal section of the operating parts of a ride showing the position of the parts just after tiring. Fig. 2 is a similar section after the discharged shell thas been ejected and the breech-block and action har are near their rearward limit of travel. Fig. 3 is a top plan view of the action bar. Fig. 4 is an elevation of the rearward part of the same. Fig. 5 is a cross section on the line V-V of Fig. 4, and Fig. 6 shows in perspective the retainer. n

Inthe form of rifle which I have chosen to illustrate my invention the magazine A is moved with the handle or forearm B, and is provided with a springe'pressed plunger C. The barrel D is screwed into the frame or receiver E, which serves both. to connect the barrel with the stock F and to inclose the breech-block,A hammer and cartridge feeding mechanism. The rear end of the magazine A is formed into an action bar G which, as the handle B is moved rearwardly, engages, as by notch H, with the tooth or projection I of the breech-block J so as to move the latter rearwardly and-in itsmotion to cock the hammer K, as shown in Fig. 2. The action bar G is provided with a longitudnial slot G extending forwardly from its rear end, said slot being rectangular in cross section, and also with a circular slot, in which is loosely mounted a cart-ridge stop L which is free toslide back and forth in its slot. The forward portion of guard R has a slot Rf, into which the cartridge stop L projects. This slot R allows the stop L.

a limited reciprocal movement. Projecting laterally into the longitudinal slot G is a spring-pressed dog G2, whose function is to elevate the cartridge carrier M. lThis function is performed as the parts move forward from the rearward position shown in Fig. 2 to the closed. or for ward, position illustrated in Fig. l, the parts being' so arranged that, as the action bar moves rearward, the cartridge carrier enters the slot G and the dog G2 passes over the faceof the cart-ridge carrier M until it reaches the cam-grove M into which it enters under the pressure of the spring G3. As the action bar is moved forward by the handle B, the dog G2, riding in the grove M', raises the cartridge carrier so'as to raise the cartridge, as M2, and forces it into the groove J 2 on the front face of breech-block J.

Fixed between the barrel D and the magazine A is what I term a retainer N. This may be. provided with a recess N".npon its upper face to tit over a corresponding shoulder in the forward part of the receiver E, or be provided with other means to hold it in fixed longitudinal and lateral position while the magazine is reciprocated. The retainer, as shown in Figs, 1, 2 and. 6, is preferably formed with a forwardly projecting tongue Nt lying between the barrel and the magazine but not occupying all the vertical space between them, and its rearward end projects into the chamber 0 of the receiver, being formed with a beveled nose N3, and a groove or recess N2 on its under face.

The functions of the retainer N and the cartridge stop L are, generally speaking, ex-

, use, are4 entirel v avoided.

served'in Fig. 1. the rearniost cartridge in ercised as follows: In fire arms of this description the lengths of the cartridges used vary. For example, in 22 caliber riiies long and short 22 cartridges-*differ` ing from each other by a quarter Vof an inch or more in lengthare frequently load ed into the magazine indiscriminately. it the parts, and particularly the cartridge carrier, be adjusted nicely for the longer cartridges, the shorter ones may be twisted by the too abrupt elevation of their rear ends just as they are being caught by the cartridge carrier on their way froiii the magazine to the barrel. Another ditiiculty often experienced is that a second cartridge is forced rearwardly in the act of loading and becomes lodged in the chamber O of the receiver, causing trouble orl danger.

'Still another danger arises out of the necessarily rapid action of the parts in the ordinary act of loading. if the bullet end of the rearniost cartridge is in immediate contact with the tiring end or rim of the next one at the instant that the rim of the rear cartridge is thrown-neoessarilv with considerable forctagainst the breech-block J, in which condition of things there is danger of premature explosion of the second cartridge. Still another trouble is experienced when, owing to incomplete or imperfect actuation of the parts. the rearmost cartridge is not moved upward into the breech-block groove J2, and, on the forward reciprocation of theV handle G. the ca. tridge, being carried forward and not being in proper alinenient. is jammed at the mouth of the magazine. In th'e useV of my invention, however, these troubles, and others interfering with rapid and smooth action of the parts in practical As will be obthe magazine. being at the rear of the magazine proper. is held between the action-bar and the retainer which projects so far to the rear as to prevent the cartridge. whether long or short. from being crossed as itis fed back to the cartridge carrier )L As this feeding takes place it is elevated over the inclined upper and forward face L of the cartridge stop L, and so reaches the carrier M in proper position; as the rear cartridge is so delivered, the next cartridge is carried rearward by the action-bar until the cartridge stop L is arrested b v the rear end of slot R', when that cartridge is arrested, in the position shown in Fig. 2, out of contact with the rear cartridge` which in the forward reciprocation of the handle B is carried up and inserted in the ritle barrel. the second cartridge being then moved to the rear end of the actionbar by the tension of themagazine spring, to position shown by Fig, 1, ready for the next operation. Taking the condition of things shown.

in Fig. 2, and assuming that the operation the handle B will carry the rear cartridge foward with the magazine A. If suitable l provision be not' made, the cartridge, particularly at its rim, may be caught or jammed between the cartridge stop L and the rear end of the retainer as the cartridge rides downward from elevated to normal position: but with my invention. the cartridge rim will slip past the beveled nose N3, into groove N2, which allows cartridge stop L to move freely to its forward position. The se thin tongue X* of thefretainer is merely to hold the said retainer in place especially when the action bar is in its forward position. (See Fig. 1.) The tongue X* bearing against the under side of'barrel D while 35 the mid-portion of retainer bears onits lower side, against the top of the action bar the rear end of retainer is prevented fromdropping downwardly and thereby disengaging the retainer from its engagement withthe receiver. This'engagement is by means of the recess N in the topof the retainer.

From the foregoing my invention will be readily understood. It may be .varied in man v particulars and may be applied to other uses th'an those illustrated and described. l

What I claim as my invention is 1. The combination' in a. tire arm, of a re- 100 ciprocating tubular action bar havingv at. the rear an outlet opening for cartridges transverse to the length of said bar, a carfVV tridge .stop with reference to which the magazine reciprocates and arranged to deflect 105 the rearinost cartridge into the outlet opening when the same is passing the cartridge stop, and a retainer forward from the cartridge stop to preventthe upward:y turning .of the cartridge as the same enters'the re- 110 ceiven said retainer having a recess in the lower portion thereof adapted to receive the rim of a cartridge and allow said cartridgestop to pass said rim from the rear to the` front side thereof.

9. In a tire arm, a reciprocating action bar. a cartridge stop, in combination with a retainer located *above the action bar and projecting into the receiver, said retainer having a recess in the lower side-thereof adapted to receive the rim of the cartridge and allow the cartridge stop to' pass the said rim from the rear to the front side; thereof, and means for holding said'ie` tainer in position.

3. In a tire arm, a reciprocating action bar, a cartridge stop, in combination with a retainer having a beveled nose NA, a recess N on the upper portion thereof adapted to tit a shoulder on the receiver, a recess in the lower portion thereof between the nose N3 and recess N' adapted to receive the rim ,of the cartridge and thereby allow the cartridge stop tov pass the said rim from the rear to the front side thereof and means for holding the same in position. Y

4:. In a re arm,'a retainer having a beveled nose N3, a groove NZ-adapted toreceive the rim of a cartridge, a forwardly projecting tongue N4, and a recess Nbetween the groove N2 and tongue N4 and adapted to engage over a shoulder to hold the saine in place. Y

5. In a fire arm, a retainer having at one end a projecting nose, the other end thereof adapted to be engaged to secure the said retainerA firmly in the fire arm, said retainer 'having a recess N2 in the lower side thereof JOHN D. PEDERSEN.
