REPEATING. FIBRA-RM. j

.Be it known that I', WILLIAM H'. GATES, aA citizen of the United States, residing. at Norwich, in the countyof New London and State of Connecticut, have invented a certain newand useful Improvement in Repeating Firearms, of which the following is a speci- Iication. u l

This invention is in repeat-ing fire arms, and has special relation to so called slide action repeating shot guns, although thedominating elementar ent improved arm cou d in repeating ries. y

My present improvements relate chiefly to the lock 'and cartridge-handling mechanisms of sucharms and `I' have particularly 1n mind-'to provide a strong, safe and simple f bolt action which has no exposed project- 1ng parts. I have also provided what I befeatures of my resbe as readilyuti ized `lieve to be a novel type of gate, or cut-o"to prevent the passaofe of more than one car-y tridge at a time fi'om the ma azine to the. carrier mechanism. Incidenta tures ofthe said-arm have been .I have explained hereinafter. These several features -of improvementl are clearly illustrated in the annexed drawings, Figure 1 beinga side elevation of. an arm embodyingl my saidy invention. Fig; 2' isa relatively eny other f eaimproved, as

ing in the direction ofthe arrow. Fig. 7 is 4 a side elevation, partly broken away,of the -engaging portions of' the receiver and barrel showing particularly the cutoff for preventing the undue escape ofthe cartridges from the magazine into'the receiver, and also the means provided for operating the said cutoH.' Fig: 8 is a transverse, sectional, View taken onvthe line 8 8 of Fig. 2, looking'in the direction of the arrow. In Fig. 9 Il have shown,in perspective, the trigger plate having the trig er and sear pivoted therein. Fig. 10 is a view of the bolt, showing thering-pin, ex-

tractor and ejector mounted therein and Fig..

11 is a view of said bolt taken'from the side opposite to that of Fig. 10. F1g.12 1s a perspective vieW- of the carrier by means of' which the cartridges are raised from the levell of the magazine to the level of the barrel. Fig. 13 1s a perspective view of the extension rod 19 andFig. 11 is a perspective view of the safety lever33 which co-acts with the trigger. l.

Invthese drawings the reference numeral ongitidinal, central, sectional 10 indicates the stock of' the arm, 11V the receiver, which serves vas a housing. for the lock and cartridge-handling mechanlsms; 12. is the barrel and 13 the ma azine tube; sald magazine tube beinglocate underneath the barrel and beingsupported' atv its front end portion in aring 14k secured to the barrel;

the magazine tube being free to slide in said' rinfr whenever it becomes necessary or desirable to se varate the barrel from the receiver. The arrel has fixed to its rear end portion a plate 15 conforming in outline to the'cross section ofA the receiver, the lower portion of said plate vhaving an opening adapted to'receive a nut 16 loosely mounted on the rear end'ofthe magazinetube, and?v threaded "exteriorly to as seen inFig. 3 of the4 said nut being screw luto the receiver,

thedrawings. The said* nut then serves as ioo a supportfcr. the rear end'of the tube l13 and.- also'as a' dowel'to prevent thedis lacement' j of' the plate 15, as well: asthe acci ental 11nscrewing of the barrelv fromthe receiver.

Mountedto 'move longitudinally u on the" magazinetube13y is hand slide 17 aving ceiver, y

haps more important, purpose which I will secured thereto a bar 18 whichlatter extends rearwardly and has interlocked therewith an extension 19 which is covered and protected, when the arm is completely assembled, by a plate 20 slidably mounted in a dove-tail groove in the side of the receiver. By means of the hand slide `17 and the attached, twopart, bar 18-19, the lock-mechanism and other operative parts, may be readily actuated in order to eject a dischar ed shell and to transfer a fresh cartridge from the magazine to the barrel and, simultaneously, to cock the arm and set the trigger.'

In the receiver portion, into which the barrel is screwed I have provided a xed annulus 21 which forms one vof the irnportant features of my present improvement. This annulus is so located that it serves as a substantial abutment for the barrel end, when the barrel is screwed home in the .reand it also serves another, and perex lain.

rdinarily the rear endA portion of the barrel has to be notched, or otherwise recessed, to receive the free end of the extractor hook, in order that the said hook may lie in front of the flanged'cartridge head and, when the extractor is thus seated in the barrel notch, it eiectually locks the barrel 'a ainst rotation and it 1s therefore impossibile to separate the barrel from the receiver until the arm has been cocked or, at all events, not until the extractor hook has rst been withdrawn from the barrel notch. In my improved construction the notch for the reception of the` extractor is made in the xed annulus, as seen at 22 in Figs. 2 and 3, thus rendering it unnecessary to cut into the barrel end, and leaving the barrel end free to be rotated, or partially rotated, in order that itv may be detached from the receiver.

As each cartridge passes rearwardly from the magazine tube 13 into the receiver it is deposited upon a carriert23 which is fulcrumed at 24 inthe said-receiver; the said carrier being then elevated, as seenin Fig. 3 to .raise the cartridge into alinement with the barrel and so that it (the cartridge) ma be forced forward, and seatedV in the barre by the forward movement of the bolt. The rear end portion of said carrier is formed with two projections 23a 23b the former of which is located at the rear of the carrier fulcrum and the latter at the front of said fulcrum, said projections being adapted to be engaged alternately by a bracket 25 carried by the sliding bar 19, that is to say when the said b ar is slid rearwardly, the attached bracket 25 engages the projection 23a and forces the rear end of the carrier downward and thus eleva-tes the free front end of said carrier and, per contra, when the bracket 25. is moved forward again, to return it to its normal position, it (the bracket) engages the projection 23b and thus rocks the carrier downward to its initial osition, ready to receive the next cartridge from the magazine tube. In order to prevent the premature return of the carrier from its elevated position to its initial position, I have provided in the side wall of the receiver a springpressed plug 26 whose rounded end enters a depression in the carrier, when the latter is in its elevated position (see Fig. 8) and thus serves frictionally and temporarily to prevent the premature downward movement of the carrier.

The trigger 27 is pivoted in a plate 28 that is secured to the receiver by a pin 29 at one end and by a screw 30 at its other end and the sear 31 is pivoted in a stand 3la formed on the said plate 28, as will' bebest understood by reference to Fig. 9 of the drawings. The sear 31 has two rearwardly projecting arms the lower of which is adapted to be engaged by the trigger and the upper of which is so located that it may be engaged by the head 45a -of the firing pin when the bolt is slid rearwardly to cock the arm (see particularly Fig. 4). When the trigger is pulled,`to discharge the arm, the sear is rocked downward until its upper arm is'released from engagement with the firingpin head when said firing-pin is sna ped forward as I shall explain more fully later.

I desire to call particular attention vto two forms of safety devices which I have provided in connection with the trigger in order to prevent the accidental discharge of the arm before the new cartridge is completely seated in the barrel, and the bolt is securely locked in its home position in the receiver. One of said safety devices consists of a lever 33. that is pivoted on a screw 34 in the side wall of the receiver at, or about, the same point where the sear is pivoted. The rear end of the lever 33 is adapted to be moved into the path of a stud 27El on the trigger and the front ends of said lever bears a stud 33a that lies in the path of a rib 19a on the sliding bar 19. When the saidbar is in its forward,or normal position, as seen in Fig. 2, the rib 19a holds the safety lever out of locking engagement with the trigger stud 27 but so soon as bar 19 is moved rearward the rib 19. passes away from the lever stud 33a and the said lever is permittedl to rock on its fulcrum soas to move its rear end into locking engagement with the trigger study. The trigger 1s thus prevented from being pulled oi until the bar 19 returns to its normal position and the bolt has been safelylocked in its home position in the receiver. I have also provided another safety feature in the form of an upward extension 27 b on the trigger that lies in the rearward path of the bracket 25 which I have already referred to. When the said bracket engages then said trigger extension and positively rocks the trigger into position to receive the safety lever 33. If this were not so the-trig er proper might be held rearward by the-finger of the gunner in which case the Sear would be held out of engage-l ment with the firing-pin and the latter would return with 'the bolt instead of being retained by the sear.V Y The cartridge cut-off, which I have already briefly mentioned, is best seen in Figs. 6 and 7 vand consists essentially of a bolt 35 mounted to slide vertically in a hole in the side of the receiver, said boltbeing held normally in its elevated position by a spring 36. The bolt 35 is formed with a lateral iin 3 5 that extends -into the path traversed by the cartridges as the latter pass from the magazine tube into the receiver, as is clearly illustrated in Fig. 6; The sliding bar 19 is l0- cated immediately over the upper end of the said bolt 35 and said bar has pivoted thereto a pawl 37 whose free end enga es the said bolt, and forces it downward, w en the bar 19 is moved rearwardly (see Fig. 7). This Vdownward movement of the cut-off 35a occurs at the tirst rearward movement of the bar 19 and said gate is held open justy long enough to allovs7 the passage of the head of the cartridge then seeking to pass into the receiver. As said head passes the cut-ofi'l the pawl 37 passes out of engagementwith bolt 35 and the spring 36 forces said bolt upward again, thus moving the cut-0H fin into position to check the rearward movement of the next cartridge in the magazine. When i dinally in the chambered upper portion of.

the bar 19 is slid forward agaln the pawl 37 yields `and passes over the end of bolt 35 without disturbing the latter. v

I will now describe the lock-mechanism bolt and the parts immediately connected therewith. The said bolt vindicated bythe reference numeral 38, is of the usual cylindrical form and is adapted to slide longituthe receiver. Loosely mounted' on bolt 38 is a tubular section 39 which is ,formed with longitudinal ribs 3954-39b that project ra dially from the circumference of said section 39, the said lribs being so located that they may be rocked into engagement with solid portions of the receiver wheny the bolt 38 is 1 in its normal or closed position, in order to lock the said bolt a ainst endwise deflection. The rib 39a thusl loc s against the upper wall of the receiver (see Figs. 1', 4 and 5,)1and the rib 3.9b thus locksagalnst the lower wall of the bolt chamber (see Fig. 4). When it is desired to'slidc bolt 3S vrearward, as in the act of extracting an empty ,'shell and cooking the arm, the tubular section 39 is first rocked suiiiciently to move theribsl 39a. 39b out of abutting engagementwith the solid portions of the receiver, and such rocking movement is produced by a 'stud 19b on the sliding bar' 19; said stud lying in a spiral groove orchannel cut in the lower circumferential wall of the section 39 as is plainly seen in Fig. 3 of the drawings. The first rearward movenient of bar 19 causes the tubular section 39 to rock on bolt 38 sufficiently to vmove the ribs 39a -39b out of lockin engagement with the receiver, and continue movement of said bar 19 and its stud 19b operates to slide thebolt 38 and 'its attached arts rearward; the rib 39a meanwhile sliding in an internal channel in vthe top of the receiver F 3).

Secured to the front end portion of the bolt 3,8 is a spring extractor hook 40 of ordinary construction, andl mounted to slide .a limited distance in thelower front portion of said bolt is an ejector 41. The tiring-pin isdenoted by the reference numeral 42. The mainspring is confined between a shoulder 42a on the firing-pin head and a nut- 44 screwed into the rear end of bolt 3,8. Upon the extreme rear end portion of the .firingpin is iixedly mounteda head 45 which 'has a downwardly project-ing spur 45l that is adapted to engage the sear, as seen in Fig. 4, to hold the firing-pin rearward when the bolt 38 returns to its home position after reloading the arm.

I have found it desirable to lock the tubuhas been reloaded, in order that the loaded cartridge in the barrel may not, by oversight, `be thrown out, and this I have accomplished by pivoting in the side of the recelver a' spring latch 47 whose front end is formed with a projecting nose adapted to enter a slot 39a in the tubular section.` 39 when thebolt is in its home or forward position in the receiver, thus effectually preventing the rotation of section 39 until the arm is discharged, whenthe firing-pin head enages a project-ion 47a on the inner side of atch 47 and forces the nose of the latch outof locking engagement with the slot 39c (see Fig. 5). If, however, it should be desired to unlock section 39 without first discharging the arm it may be `accomplished by means of a thumb-piece 47b extending out- (see lar section 39 in the receiver after the arm f wardly through a` hole in the side wall of the receiver.

I wish to direct particular attention to the fact that the o lerative vparts of my improved arm, as ierein described, are completely linclosed and protected fromthe action of the elements, also that the various elementary parts are of strong construction and they are mainlyrpositive in their operations.
