. There has recently come into use a high speed twenty-two caliber cartridge having a speed of twenty-five hundred feet per mlnute and a blank range of approximately two hundred yards In order to avoid the-necessity of designing a new rifle to handle these cartridges I have devised novel means whereby the higher caliber rifle movements can be adapted to utilize these high speed cartridges, the barrel being replaced by one which is adapted to receive a twenty-two caliber cartridge. With the above and other objects in vlew, as will hereinafter appear, my invention comprehends novel loading mechanism for rifles. i

It further comprehends novel rifle loading mechanism wherein the bolt is providedwith a novel constructionand arrangement of a cartridge pick-up.

It further comprehends a novel magazlne and novel means for securing it to the floor Other novel features of construction and advantage will hereinafter more clearly appear in the detailed description and the appended claims. y For the purpose of illustrating the nvention, I have shown in the accompany ng drawing a typical embodiment of 1t, winch, in practice, will give satisfactory and reliable results. It is, however, to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized, and my invention is. not lim- 7 ited to the exact arrangement and organization of these instrumentalities as herein set forth.

Similar numerals of reference indicate corresponding parts. i i 1 Referringto the drawing: p

l designates the breech of a light weight rifle embodying my invention. 2 designates the barrel having a bore to receive a .22 cartridge. 3 designates the bolt which is constructed and operates in the conventional manner except for my novel-cartridge pickup 4. The bolt is slotted as at 5 to receive the cartridge pick-up, and the rear end of such slot terminates .in a rounded recess 6 adapted to; receive the rounded head 7 connected with the body portion of the cartridge pick-up bya neck 8. The extractor ring 33 which is seated in an annular groove inthe bolt extends over the heads-7 so that the car tridge pick-up is, pivotally, supported at its rear end. A spring 9 between the bolt and the cartridge pick-uptends ,to move the forward end of the latter outwardly. The bolt and cartridge pick-up are recessed to receive and position the free ends of the spring.

The conventional magazine is of such size that-it cannot be used with a .22 cartridge. It therefore becomes necessary to redesign it for this purpose. The magazine consists of a casing 10 preferably rectangular in contour and; provided with a rearwardly extending base flange 11 which extends beneath a spring metal clip 12 having one end secured to the floor plate 13 by means of a fastening devicel nl The magazine-has within it a spring 15 having a zig zag contour,-and the forwardly extending lower portion is adapted to pass beneath the inwardly directed flanges 16 of :the floorplate. The spring 15 at its upper end terminates in a forwardly extending portion which abuts against the downwardly-directed forward'flange 16 of thecartridge follower 17 which has a similar flange 183131118 rear end. Opposite side walls of the'magazine are inwardly deflected at their upper ends as at 19 to overhang the cartridge follower and limit its upward movement. 20 designates a stop and magazine cover in the form of a bent spring, the lower end of which is secured to the Usage.-

7 upper end as at 23. The forward upper en of the magazine is cut out as at 24. The cartridge follower has a raised rib 25. The breech has the rounded shoulder-'26 which directs a cartridge when fed forwardly-byth e es-r tridge pick-up to the bore of the barrel. 27

are the conventional locking lugs on the bolt: and 28 is the bolt handle.

29 is the conventional entractor carried by the bolt. 30designates the cartridge. p

The operation will now be apparent to those skilled in this art andis as follb'ws,

Assuming that the cartridges are in the ma a'zine, the bolt handle 28" is raised and the jolt 3'retrac ted. The bolt moved forwardly. The rim o f the cartridge is resting against the stop' 22 and as the bolt advances the upper end of'the spring 20 is pressed downwardly theca'rtridge pick up 4 'sothatthe forward end-of the latter sonnets with the rim ofa cartridge and moves thelatter forwardl with it. The forward end of the cartri ge "rides up .on

' the shoulder 26, see Figure 2, and is directed into the bore of the barrel, The bolt handle 28 is now swung downwardly and the bolt is locked imposition with the pin 31 'i'eady to be released b the trigger 32.

It Will be noted that t e magazine housing 34 has'con'nected to it the floor plate and thus "forms an outer magazine within is detachably mounted art cartridge maga- Zinc 10. p I It willno'w "be apparent that I have devised "a new and use-n11 rifle loading mecha nism which embodies the' features of advantage enumerated as'desirable' in the statemnt'o'f the invention and theabove description, and while I have, in the present instance, shown and described a preferred em bodiinent thereof whicihiWill give practicesatisfactory and reliable results, it is to understood'that this embodiment is susceptible of modification in "various particulars without departing from the spirit or scope of the invention orsa'crificingany of its advantages.

Having thus describedmy invention what I clalm as new and desire to secure by Letters Patent, is

I. In'a'rifie loading mechanism, thebombination with the bolt bodily rotatable -into locked position and a fixed and stationary barrel, of a cartridge pick-up movably car ried by said bolt andf'efiective on the forward movement of the bolt to feed a cartridge into said barrel. i i Y 2. In a. rifle loading mechanism, the coinbination with'the breech, of a bolt bodily 'rotatable'into locked position, a' barrel fixedly connected with said breech, a cartridge pickup movably carried by the bolt and effective on the forward movement of the bolt to feed a cartridge into said barrel, and a spring tending to move the free end of the cartridge pick-up away from said bolt.

3.
