. cartridges, the barrel. being ,repla'cedby one which is adap ted to receive a twenty-two calr r r g I. r

, With theabove and other objects? inview, as wi ll;hereinafter appear, my invention comprehends novel loading mechanism for TQS L- .a- 1 v It further comprehendsnovelrifle loading mechanism wherein the bolt is-provided with a novel construction and arrangement of a rtr dg Pi ker It. further comprehends, a novel magazine and-novel means for securing it to the floor p a Qt her novel features of, construction. and advantage will hereinafter 'more clearly appearin thedetailed description and the appended claims. r

; For the purpose of illustrating the invene tion, I ;have. shown in the accompanying drawings a typical: embodiment of it, which, in practice, will givesatisfactory and reliabl'e, results. It is, however, to be understood that the various instrumentalities of which my invention consists canzbevariously arrangedand organized, andmy invention is notil-imited to the exact arrangement and organization of these instrumentalities ashereinset-forth; r

Eigurelis aside elevation of a portion of a rifle, embodying my inventionr Figure, 2.- is-a sectional elevation of the loading mechanism. 1 A j Figure -3.'is a-'perspective view, showing more particular-ly ,v the forward end of the bolt and the cartridge pickup.

- I imilar numerals of reference indicate corresponding parts-4* Referring to the drawingsi .l -designatesg the breech of a light weight rifle embodying my invention. 2 designates the barrel having a bore to receive a 22 cartridge, Sdesignates-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, andthe rear end of such slot'terminatesin a rounded recess 6 adapted to receive the rounded head 7 connected with the body portion of the cartridge pick-up by a neck 8. The, extractor ring 33 which is seated in an annulargroove-in the bolt eX- tends over'the-head 7- so that the cartridge pick-up is pivotally supported at its rear end, A spring 9 between the bolt and the cartridge pick-up tendst'o move the forward end of the latteroutwardly. 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 thereforebecomes 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 13by means of a fastening device 14. The magazine has within it a spring 15 having a zig zag contour, and the forwardly extending-lower portion isadapted to passbeneath the inwardly directed flanges: 16 of the floor plate. T-he. springf15' at-itsupper end terminates ina forwardly extending portion 5 are inwardly deflected at their upper ends as ill! 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 magazine by a fastening device 21. The

spring extends rearwardly and upwardly and is then deflected forwardly and upwardly and terminates in a downwardly directed ange 22 which bears against the rear wall of the magazine which is cut away at its upper end as at 23. The forward upper end 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 by the cartridge 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 eX- tractor carried by the bolt. 30 designates the cart-ridge.

The operation will now be apparent to those skilled in this art and is as follows Assuming that the cartridges are in the magazine, the bolt handle 28 is raised and the bolt 3 retracted. Thebolt 3 is then moved forwardly. The rim of the cartridge is resting against the stop 22 and as the bolt advances the upper end of the spring 20 is pressed downwardly by the cartridge pick-up 4 so that the forward end of the latter contacts with the rim of a cartridge and moves the latter forwardly with it. The forward end of the cartridge rides up on the shoulders 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 in position with the firing pin 31 ready to be released by the trigger 32.

It will be noted that the magazine housing 34 has connected to it the floor plate and thus forms an outer magazine within which is detachably mounted the cartridge magazine 10.

It will now be apparent that I have devised a new and useful rifle loading mechanism which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that this embodiment is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention "what I claim as new and desire to secure by Letters Patent, is I 1. In a rifle loading mechanism, the combination with the bolt rotatable into locked the barrel of the rifle.

2. In a rifle loading mechanism, the combination with the bolt rotatable into locked position, of a cartridge pick-up movably carried at its rear end by the bolt and effective on the forward movement of the bolt to feed a cartridge into the barrel of the rifle, and a spring tending to move the free end of the cartridge pick-up away from the bolt.

3. In a rifle loading mechanism, the combination with the bolt having a slot opening through its forward end of a cartridge pickup seated in said slot, 'an'extractor ring retainingthe rear end of said cartridge pick-up on the bolt, and resilient means tending to move the free end of said cartridge pick-up outwardly from the bolt.

4. In a rifle loading mechanism, a bolt having in its bottom a slot opening through its forward end, the rear end of said slot terminating in a rounded recess, a cartridge pick up seated in said slot and having a head to enter'said recess, means to retain said head in said recess, and a spring between said bolt and the cartridge pick up and tending to move the forward end of said cartridge pick up away from said bolt.-

5. In a rifle loading mechanism, a magazine housing, a floor plate detachably connected therewith, a sub-calibre magazine insertable into said magazine housing and interlocked at its lower end and with said floor plate, a cartridge follower within said sub-calibre magazine, and a spring having one end engaging said cartridge follower and its opposite end interlocked with said floor plate.

6. In a rifle loading mechanism, a magazine housing, a floor plate detachably connected therewith, a sub-calibre magazine insertable into said magazine housing and interlocked at itslower end with said floor plate, a cartridge follower within said sub-calibre magazine, a spring having one end engaging said cartridge follower and its opposite end interlocked with said floor plate, and a resiliently mounted cartridge stop at the rear end of said sub-calibre magazine. 3

7. In a rifle loading mechanism, a magazine housing of normal calibre, a floor plate detachably connected with said housing, and a sub-calibre magazine insertable into said housing and connected with said floor plate.

8. In a rifle loading mechanism, a magazine housing of normal calibre, a floor plate closing the bottom of said housing and detachably mounted, a sub-calibre magazine housing havingone of its walls detachably con nected with said floor plate, ,a cartridg follower in said housing, and a spring to effect upward movement of said follower and having one end detachably connectedwith said floor plate.

9. In a rifle loading mechanism, a magazine housing of normal calibre, a floor plate covering the bot-tom of said magazine, a spring fixed to said floor plate, a sub-calibre magazine having means to pass beneath said spring and floor plate to retain the parts in assembled condition, a follower in said sub-calibre housing, a spring Within said sub-calibre housing having one end portion bearing against said follower, and having its lower end portion interlocked with said floor plate, and a resilient cartridge stop carried by said sub-calibre magazine housing.
