3mm M .TRIIULOFF JOE BUDLOFF, OF BAGGS, WYOMING.
Application filed July 7, 1915.
To all whom it may concern: D
Be itknown that I, Jon RUnLorr, a citizen of. the United States, residing at Baggs, in the county of Carbon and'State of Wyoming have invented certain new and useful Improvements in Firearms, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to certain improvements in fire arms and has relation more particularly to a device of the general character of a magazine type; and it is an object of the invention to provide a novel and improved fire arm wherein the magazine is p sitioned within the grip or stock and wherein the shells are discharged through said grip or stock.
The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved fire arm whereby certain important advantages are attained and the device is rendered simpler, less expensive andotherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.
The novel features of the invention will be carefully defined in the appended claims.
In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view, partly in section and partly in elevation, of a fire arm constructed in accordance with an embodiment ofmy invention; Fig. Zis a transverse sectional View taken through the stock or grip of the fire arm as herein disclosed," Fig. 3 is a longitudinal sectional view taken through the re ceiver and adjacent portions of the barrel and grip, with 'the major portion of the grip shown in elevation; Fig. 4 is a horizontal longitudinal sectional view taken through the barrel and receiver as herein embodied. with the breech block shown in retracted position; Fig. 5 is a view in perspective, detached. of a locking vmember herein embodied; Fig. 6 is a fragmentary view in rear elevation of a magazine herein emplcycd;
and Fig. 7 is a fragmentary view in front I elevation of the magazine opposite to that shown in Fig. 6.
As disclosed in the accompanying crawlugs, 1 denotes the receiver, 2 the barrel, and
" 2- the grip or stock, said grip or stock being hollow and in communication with the in- Specification of Letters Patent.

Serial No. 38,541.
terior of the receiver and having its lower end open and said grip or stock is also divided into two compartments a and b by the partition 4 extending in a direction longitudinally of the firearm, the compartment av constituting the magazine chamber and the compartment 6 constituting an ejecting chamber through which the shells are adapted The partition 4 gradually increases in thickness from itslower end and adjacent its upper end is provided with an opening 5 in which the plunger 6 works and in which is mounted the trigger 7.
W'ithin the receiver chamber and engaged with the upper end of the partition l is the breech block 8 of the blow-back type with which coacts, in a conventional manner, the recoil spring 9 and disposed through said breech block is the hammer 10 with which coacts the firing spring 11, said hammer being retracted under the influence of the rearward movement of the breech block and consequently placing the firing spring 9 under tension. The hammer is maintained in its retracted position through the medium of the sear 12 coacting with a lug 14 carried by the hammer and said sear automatically on gages the lug under the influence of the spring 15. The trigger 7 coacts with the sear 12 in a conventional manner.
16 denotes a safetymember engageablewith the sear in advance of its pivot and adapted to lock the same against movement under the influence of the trigger 7 and, as herein disclosed, said safety member is carried by the shaft l7 projecting exteriorly of the stock or grip 3, the exterior portion of said shaft being provided'with a finger-piece 18 whereby the safety member may be adjusted into or out: of the engagement with the scan The breech block 8 has pivotally engaged therewith a conventional extractormemher '19 adapted to coact with the flange of the shell S in a well-known manner and to withdraw said shell when the breech block is forced rearwardlv under the influence of the recoil and whereupon said shell is adapted to be ejected through the compart ment Z The inner face of the breech block 8 I provided with a longitudinally disposedgroove 20 in which is pivotally mounted the feed member or arm 21, the forward ex tremity of which being under'the influence of the spring 22, whereupon-said feed memher or arm will be caused to engage behind the uppermost cartridge within the magazine M Within the chamber a as the breech block 8 is forced rearwardly whereupon said cartridge will be properly positioned Within the barrel 2, or more particularly the firing chamber thereof, when the breech block is returned under the influence of the recoil spring 9. The magazine M is of conventional construction and a' detail description thereof is therefore believed to be unnecessary.
The breech block 8 is provided with the depending lip 23 with which the plunger 6 coacts in order to initially adjust the hammer 10 into firing position. I also find it of advantage to provide the outer or rear end of the receiver 1 with an opening 24 through which the hammer 10 may pass so that no obstruction will be offered to the retracting movement of said hammer.
From the foregoing description, it is thought to be obvious that a fire arm constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and it will also be obvious that my invention is susceptible of some change and modification without material departure from the scope of the appended claims and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.
1. The combination", in an automatic fire arm, with a receiver and a hollow grip in communication therewith and the lower end of the grip being open, a partition dividing the grip into two compartments longitudinally thereof, a magazine insertible in one of said compartments, a spring-pressed and recoil operated breech block slidably en gaged with the upper end of the partition, an extractor member carried by the breech block for extracting the shell and delivering the same within; the ejecting compartment of the grip, and a feed arm carried by the breech block engageable with the cartridge within the magazine for forcing the cartridge into firing position, the opposite faces of the partition being arranged in downwardly converging planes.
2. The combination, in an automatic fire arm, with a receiver and a hollow grip in communication therewith and the lower end of the grip being open,a partition nally thereof, a magazine insertible in one of said compartments, a spring-pressed and recoil operated breech block slidably engaged with the upper end of the partition, an extractor member carried by the breech block for extracting the grip, and a feed arm carried by the breech block engageable with the cartridge within the magazine for forcing the cartridge into firing position. In testimony wherof I hereunto afiix my signature in the presence of two witnesses.
