To all whm'n/ it may concern:

'Be it known that I, HENRY J. Boosrnp, residing in Kenosha, in' the county of Kenosha and State of l/Visconsin, have invented 5 new and useful Improvements in Repeating Shotguns, of which the following is a description, reference being had to the accompany- .ing drawingswhich are a part ofthis specification.

This invention relates to repeating shotguns, and has for its object to provide a shotgun of this type with a Construction by which it may be rigidly connected when in use and readily separated or taken down when desired to be capable of a compact arrange ment of its parts for convenience in carrying it from place to place.

Another object of this invention is to imrove upon the breech-block operating and ocking mechanism, the shell-ejector, the

shell-lifter, the lock mechanism, and the magazine, whereby a take-down repeating shotgun is produced with few pa-rts, is strong and simple in its construction, and the parts.

can be readily disconnectedforcleaning pu'rposes.

. With' the above and other objects in view the invention consists in the repeating shotgun hereindescribed, its parts and combina- 30 tions of arts, and all equivalents.

Referring to the accom anying drawings,

in which like characters reference indicate the same iparts'inthe several views, Figure 1 is a side e evation of a repeatlngushotgun constructed in accordance with t s invention.

Fig. 2 is a sectional view thereof withparts shown in elevation. Fig. 3 is .an enlarged sectional view of the breech mechanism with the parts shown in the positions assumed by them when the gun is discharged. Fig. 4 is a somewhat similar view showing the parts in the positions assumedby them when the breech-block is thrownfto itsrearmost osition. Fig. 5 is a sectional plan view 0 the mechanism with the parts in the"positions shown in Fig. 4 and representing by dotted lines the ejectionof' an emptyshell. Fig. 6

showing the'open position of its clamping member in dottedlines, parts being sectioned. Fi 11 is a plan view thereof. -Fig. 12is'a sioe elevation of the fore-arm and the breeoh+ block removed from the other parts and in the closed condition of the breech-block, parts being sectioned. Fig. 13 is a plan view 'of the connecting-rod between the breechblock and the forearm. Fig.14 is a rear elevation of the breech-block. Fig. 15 is an elevation of the magazine in its open condition. Fig. 16 is a transverse sectional view thereof on the line 16 16 of Fig. 15. Fig. 17 is a similar view on the line17 17 of Fig. 15, and Fig. 18 is a plan view of the triggerguard.

In these drawings, 20 represents the barrel, and 21 the'magazine carried therebeneath, both being removably connected to a breechcasin 22 on an ordinary gun-stock 23. The breec casingRQ is of a rectangular box-like formation with a heavy front end wall 24 and a removable bottom 25, the barrel 20 being threaded in said end wall '24 on screwthreads 26 and the magazine-tube 21 having therewith. A connecting-plate 27 is 1igidly mounted on the end of the ma azine-tube -'an opening through said end Wall registering clamping member 29, provided with teeth to engage with an annular series of teeth 30, formed around the barrel screw-threads 26. The unlimged portion of the barrel-clamp of the connecting-plate is also provided with teeth for engaging the teeth 30 of the barrel, and a screw 31 connects. o

the clamping member to the connectingplate to tightly hold the barrel against accitightly into the breech-casing. An annular flan e 32 is formed on the barrel ahead of,the teeth 30, preferably by seating a ling or collar in a groove thereof, which flange is adapted to fit within a groove 33 of the connectin plate and clamping member to form a loc ing engagement etween the connectingplate and the barrel.

A breech-block 34 is slidable longitudinally in the breech-casin 22 upon guide-flanges ust ahead of its dental turning after it has been screwed Y 35 on its sides, whic travel in grooves 36 in the sides of the breech-casing, said breech; block being capable of passing through me rear end wall of -the breech casm in its open position and being adapted to. ear against the rearend of the barrel in its closed po- BitiOl'l.

A firing-pin 37 passes longitudinally through the breech-block and projects from.

' one end or the other thereof, usual, with its front end in position to strike the oap oi" the closed. The firing-pin is eon'l'ined in its movements', as. usual, by a set-serew 38, passing through. the side of the lneeeh-bloek and entering a. slot of the firing-pin. I

breech-block in sockets thereoll When the breech-blook is closed, as shown in Fig. 3, the locking member l oreed downwardly l y the spring 40 to engage the rein.- end wall :22 of the breech-easing, and thus prevent the breech-block moving rearwardly from the re- The locking member 39 front end with it stop shoulder or depending 111g 42, with which the cam-lug i3 outhe remend of at conne0tingrod 44 is adapted to engage, said connecting-rod sliding in iiv groove in the breecl'i-eesing and passing through registering openings in the end wall and the eoni'iee-ting-plote 27 and. connecting with a. grip or fore-arm 45, whiehis slidavble on the megnzinetube 21. The locking member is also provided with at front stop to be engaged by the coin-lug 43. and this ronmrises v a hooleshoped slide 46, which is countersunk in the side of the breech-block and is capable of being swung epiwirdly out ol' the path of the com-lug 43, but which is normally held in its lower engaging position by means of it spring-pressed pin 47 in the breech-block entering a. notch in said slide. as shown in Fig. 6. When the l'n'eeeh-hloek is closed and the ports are in the positions shown in Fig. 3, the

fore-arm 4.5, on being forced reorwnrdly lo- .Werd. the gun-stock. moves the mun-lug 4?;

along the inclined com-surl'iioe 4i ol' the lmrhing member 39 to lift said. locking n'iember out of ei'igagement with the rear wall 22 oi the breeelncnsing. When this is ereomplished, the breech-block is unlocked and the com-lug 4?, morning into eng: 1 inept with the depending stop-lug 42. moves said breeele block lfittiwztl'dly on its guidehinges 35 to the position. shown in vllig. l. The forward movement of the lore-nrn1 45 will now cause the com-lug 43 to leave the stop-lug and come into engagement with the front stop 46 and pull. the in eh-blo vi;

shown in l ir 3, when the looking member 39 springs down into engagement W1 th the real- 1 J 1 1 1 W111i 22 to leek the breeen-block in place.

A shell-lifter 48 with upstanding side Wings 49 has its rearWnrdly-extending sten'i 50'eonneeted to a block 51, which is pivotforwerdly thereby 7 until it s again. in. its closed position, as

eseoie block to swing the shell-litter upwardly, as

shown in Fi 1. A spring 52 is mounted on the removnole bottom .5 ol' the l)l{(('l'l(':lt mg nnd bears upon one/or the other oi :i-pmr of nuguhirly-disposed beaming-faces 5?, on the front end of the breeel'i-bloek 15 it locking bottom of bloekol, so as to hold the shellhlter in either its upper or lower position with spring-pressure. At its front end the shelldilter is provided with a downwardlywhen the shell-lifter is in other positions, and

thereby prevents the shells being fed from the nmgztzii'ie when the shell-litter is not in a position to receive them. The shell-lifter is also provided with a stop-lug 56 on its upper surface to be engaged by the shell to be lifted and holds said shell in position on the shelllifter.

Vlhen the breech-block is closed, the innerfront end engages the roar end'of the shell on the shell-lifter nud'moves it into the barrel 2!). As soon as the front end of the breechblorl; engages the inclined edges of the side wings 40 the shell-litter, which is now being held by spring 52, is moved downwardly thereby into its normal position, where the noxl. shell will ride onto it; us before.

"lhe'shell which has been carried home by the breech-block may be; diseharged by the tiriug-pin in the usual manner. and the empty shell ejected by the following means. The breech --bloek has a. cartridgeextinct or formed by :rspring-pressed catch or dog 57 set in each side thereof with a cum-faced front end projecting ahead of the breech-- block and traveling in grooves 36, so that as the breechhlo el presses the shell home in the burrel these spring-catches 57 by entering notches in the end of the barrel may ride over the rim of the shell and become engaged thmewith. Now when the breechl locl( is withdrawn. as before described, the spring- I side of the breech-casing.

shell.

longitudinal movements or breech bloclr, nos said breech-block sauces on opposite sides, drew the shell out o the barrel until it strikes egsinst a stationary lu 59onthe left side of the breech mg, whico prevents that side of the shell mov ing further to the rear, forcing the s ring-catch. on that side to release the rim. As the springeetch on the'right side continues its engagement with the rim of the shell the shell is swung laterally through an. opening 60 in the right i The force with which the shell is swung outwerdly in this catches 57, holding onto the rim of the s i L naimeris usually sufhcient to entirely eject it; but the new shell which is lifted tlierebenectb. bythe shell-lifter it this time has i tendencyto assist in the e ection of the old is prov ded with a groove or rebbet 61 in upper edge in which the lug may travel. The magazine comprises the outer an age" zine-tube 21 and on inner tube telescoping thereizyfc screw being provided at the front end of the former to ride in u longitmlinel slot the letter and prevent the inner tube being drawn. entirely him the outer fully-ez-ztended position, as

tube. The outer tube 21 has on opening termed near its from; end, nch is closed by the innertube except wlieiii the letter 28 in its .07mi A Fig. 15, I 7 1 and through this opening L shells may be dropped. one by one into the magezinotuoe 2'1.- The inner tube 62 has a follower 66 to slide therein, being pressed rearwsrdlf' by aco1l-spr1ng67, which is seated on the hanged Y head 68 in the front end of the inner time.

' flame of the i ig to press the column of shells rearwardl'yto provide for their pro Jer feed as one after the other is lifted into place, discharged, and

ejected; A clamp 70, which-is in the shape of a figure eight with the top part cut away, receives the megazine-t11be 2 and the barrel '20 and cldinps them togetherbymeanspf a screw 71 coimectiiig its intermediate portions between these members.

The breech-casing is provided with the usual reerwardlyexicnding projections 72 flior OODHQCUOH with the gun-stock, and a.

hammer-spring 73, secured to the lower thereof has its front free end pressing upiiierclly against .2: roller 74- on the hammer 75 which is piyotolly mounted in the breechcasing-iuthe rear of the end wall 22. A rec'- tongulerbl'ocl; 7 6 fits in a corresponding open- Ing in the bottom of the breech-casing to the rear, of the end wall 22 and has a triggerguard 77 formed integral therewith, Whose of the breechcasing.

Tlic lug 59 dos not into "ere with the and their relation to each other the operation front end is secured to the rein oveblo bottom A tri'ggerl'ZS is pivorally mounted in on. opening of the block 76, and a spring 79 on the projeotion-72 bears upon a shoulder thereof, so as to hold it in its normal forward position. The upstanding dog 79 of the tr1gger is adapted to engage the tooth 80, formed on. the hammer, when said hammer is cocked by opening the breechbloclr, shown in Fig. 4.

T he firing-pin 37 is provided. with 21 cam shamed depending lug 81, which stands in the of the looking member 39 of the breechclock, so that when saidlocking member is raised this cam-lug is engaged thereby and forced rciirwerclly.

With the above description of the parts is now closed by returning the inner tube 62,

compressing-the s ring 67 until the catch again engages the fl a'nged head 68 and locks the magazine closed. T0 load the gun, the fore-arm is forcibly drawn rearwardly, the connecting-rod 44 thereof pushing its com-lug 43 along the inclined cam surface 41 of the locking member 39 and lift;

ing said locking member out of engagement with the. end wall 22 of the magazine-casing, thus releasing the breeclr-block, and at the some time thc'looking member, by operating upon the cam-lug 81 of the firingp1n, Withdraws said firing-pin from its forward to its rearward position, so that there may be no danger of its discharging the shell by accident when the shellis later being pressed home by the breech-block. The breech-block being unlocked and the cam-lug 43 coming into positive engagement with the stop-lug 42 causes the breech-block to move resrwerdly against the hammer 75, forcing said hammer to its reermost position, when the breech-block passes over it and the hammer rides in a groove 82, provided therefor in the under side of the locking member 39, as shown in Fig. 4. When the stop-lug 42 started its rearward movement, the innermost shellwas allowed to follow until struck by'the lug 56 when it was in position on the shell-lifter 48. As the lug 42 strikes the upstanding block 51 near the end of the rearward movement of the breech-block, the shell-lifter 48 is raised thereby to theposit'ion shown in Fig. 4, the shells remaining in the magazine being held back by the depending lug 54 of the shelllifter meanwhile; Now the fore-arm- 45 is pushed forwardly and the cam-lug '43 is car to pull the breech-block forwardly and engage usual manner. W hen the fore-arm 45 is n means oi the spring-catches 57, until its rim strikes theejecting-lug 59 on the'left side oi the pivotal slide-stop 46 is forced upivsrdly out 01 the path of lug 43 by means of the lin- 45 its normal closed position, its spring-catehcs the empty shell which has been discharged is through the opening 60 on, the sight side of its front end xx lLIl the shell on the shell-litter 48, which remains in its upper position after the liig 42 has left the block 51, owing to the l pressure of spring .52 on said block. The shell Will be Forced to slide along the shell-lifter and into the barrel 20 by the llYGt-KllbblOC-k, and when the front end of the ln'eech-block. engages the inclined edges of the upstanding Wings 49 of the shelllifter sa-id shell-lifter Will be pressed downwardly to itsnormal position and receive the neXt succeeding shell sis-before. When the breech-block reaches 57 are sprung over the rim of the shell and its locking member 39 again springs into'locking engagement with the rear Wall 22 of the breech-casing. The hammer, which was fully cooked by'the opening of the breechblock, was prevented from following" the. breech-block when the latter was closed by. the engagementof the'dog 79 oi the trigger Wardly on the .roller'7fl, forcibly throws the hammer against the, irearwardly-projecting firing-pin 37 to discharge the shell in the operated for loading the gun with the next succeeding shell in the manner just described,

drawn rearwardly with the b'lflGGll-blOCk, b y l the breech-casing and is forced out of engagement with the spring-catch on that side, While the spring-catch on the other side remains in engagement, thus effecting the side movement of the emptyshell to eject it] the breech cesing;

'W'hen'it isdesired to take the gun apart,

ger passed through the opening {it The screw ,28, which holds the. connecting plate 27 to the front endwell 2st of the breech-cesing is removed. .The clamping member 29 J oi" this connectingplate is opened, as shown in dotted lines iii Fig. 10, so as to release the barrel and permit it to be unscrewed from the end plate 24, the clamp '70 having been loosened to nlso permit of this turning, and the barrel, with its 1nag: i;:ine,is detached from the breech --casing entirely, the connecting-rod 44 and its cam-lug passing freely through the opening in the front wall 24-. To assemble the parts again the reverse of the operation just described is perfori'ned. The locking engagement between the barrel and the connecting-plate 27, by mezms ol the series of teeth 30, enables the barrel to be ad justalrly tightened at all times to take up the wear of the parts and enables the barrel and marmzim' to-be tightly clamped to. the breech- .lering with the spring-catches 57.

With this invention the ,breech block rs firmly and securely locked-in its closed pose; tron by the locking member, and there is no d angerwhatever of the recoil throwing t open.

Furthermore, the various functions arepeT- formed by mechanism of few parts, which are the barrel more or'less without inter str ng and simple in their construction and positive in their operation, all being readily accessible for cleaning purposes.
