To all whom it may concern:
Beit known that we, ARMAND Mino and HUGO BISCHOFF, both subjects of the King of Bavaria, ARMAND MIEG residing at Leipsic, Saxony, Germany, and 'IIUeBIscHoFF residing at Berlin, Prussia, Germany, have invented new and useful Inipim'ements in `Breech- Loading Fire-Arms, (for which we have obtained a patent in Austriafllnngary, 1o No. 37,053, tome 38, folio' v529 2,751, tonie .XXIL folio 313, dated February 17, 1888; Fmgland, No. 12,882, dated September 22, 1888; Spain, No. 11,850, dated January 2, 1888; France, No. 186,001, dated September 22, 1887; 1 5" Belgium, No. 78,966, dated September 22, 1887; Italy, Reg.Gen.Vol. XXI, No. 22,334 Reg. Att.

This invention relates to improvements in `z 5 breech-loading firearms, and especially to improvements in the breech, the barrel, and the repeating mechanism.
The novel features of the invent-ion are more fully pointed-out in the following speciiication and claims, and illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal section of the fire-arm. Fig. 1l shows the barrel as seen from below. Fig. 2 is a? vertical section in thc planea: y, Fig'.l 1, and Fig. 2I is a vertical scction in the pla-ne 'y '2, Fig. 1". Figs. 3 to 5) showdetails of lthe breech mechanism. Figs. 10 to 18 represent the magazine and the dctails of the same. v
In the drawings, the letter a designates the firing-pin, which isconnected with n supplemental breechbolt`,pS, by means of a nut, l,
which isA inserted into `the supplemental,
breech-bolt and' provided with two tnppets, b b', (see Figs. 1, Lyand 5,) sunk into the front sidesof the same, andthus prcvcntin the n ut from rotating.
The supplemental breech-bolt S is coupled with the firing-pino`r by means ofa handle, c, the inner front surface of which lies on the front side ot the supplemental breech-bolt S, 'forming thus an 'immovable connection between the saine and the firing-pin a.. The handle is in this ense ofen annular shape; 'but it may also have any other suitable form.
fire, the handle has for its purpose to ook-the supplemental breechdiolt without ope lling the main breech-bolt Y, Fig. 1. To do this the supplemental breech-holt is simply withdrawn by means of the said handle, so that it is not catch is connected with the handle c, and it consists of a double-armed lever, d e, Fig. 1, which is pivoted at f between two projections of the supplemental breech-bolt The arm eof the lever is provided with a cam, e', which tits into a corresponding recess, e2, of the main breech-holt The arm d is formed as a handle lying on the handle c. In the drawings the lever is shown in the disengaged po 'sition.
gagenient is shown in dotted lines. The cam e of thelever catches into the recess e2, and thereby prevents the lsupplemental breechbolt and firing e pin from moving forward town-rd the. barrel, while at the saine time the trigger-blade r is discharged, the supplemental breech-bolt beingpushed back a little, owing` to the torinot the cam e or of the recess ei. The opening of the main breech-bolt when. the supl'ilcniental breech-bolt is cocked is prevented at the same time bythe cam e entering the recess e?. The coching is eiected by simply 'raising-thc handle d oi thelever 7 n, while the disengagement is 'eifecte'dfby pressi ng down Athc said handle. A small triggcrpin,j",'1`ig.l, secured to the lcvenarm (i and catching into the handle c, serveslto'stop the lever d c. side, which in opening' and withdrawingihe matin breech-boltv Y directed"downwai'ih 'see Figs. 1 and 9,) is, contrary tol thehitherto To avoid any accidents in the case t' a misnecessary to open the main breech-bolt. `The' The position in which the catch is in en :delivered into the barrel.
e cerne f used form, dove'aai'led and enters a correspond-A ingly-shaped groove of the lclosiiig-socket, (see Fig. 9,) in order to prevent any rocking movement of the breechbolt inthc, closing`- socket and to facilitate the working of the supplemental. breech-bolt. f
The repeatin mechanism is constructed as 'followsz ln front of the trigger-grund, att-hel `4under side of the stock or of thc barrel, is the cartri lge-inagazine M,- in which the cartridges are arranged in an oblique position, having their pointed ends turned upward and vranged in a curve tothe place where the cartridge is A spring, h, of an oblong form, which is rounded oil' at the corner and bent inward at the niiddle, (see Figs. 1 and 2,) acts'on a follower, and forces the j cartridge toward the cartridge-chamber. We have chosen this forni Iof thclspring, inorder zo.
to .reduce as muchas possible the friction bctween the spring and the Walls of the .magew zine., rlhe connection between the spring h and the follower 1f, Figi, is rendered'niovable The device for introducingtliecartridges sepa- .by means of 'the plate 7C, which on one side receives the pressure of the spring, and on theother side is connected by a pin, I, with the follower z.
The pin Z plays in a slot in the follower, so that the latter may move in the lmagazine Without any difficulty. As shown in Fig. 2,the magazine is-narrower at' its upper part, in order to guide the cartridge surely on its fore thinner end ands@ guide the spring h.
-retely into the chamber consists orl two compound pawls, m m, which are putin action hyv means of a cam, p, secured to a closing headpieoe, P, Figs. l, l0, 11, and 1.2. The compound pawls m m are fixed to movable spindles n n,
towhich are secured the' levers o o, which when in motion rotate the spindles n o?, and consequently move the pawls m m., The levers on, l5, are arranged, with respect to the closing head-piece l?, in such a :manner that Whenthe latter'opens the main breech-boltthe cam p passes between the levers o o and separates the top ends of the same, and
thereby oscillates the pawls fm rm. 'After the l 'quently also separates the upper parts of the cein phaspassed betweenthe levers o o the.
latter arebrought siticn's'.
liigs..13,'1 =l, and 15- explain. the operation of bach into their former pothe pawls. vAssuming the cartridge Xo. l-t-o bein the chamber, from which it is introduced by the main breech-bolt into the barrel, the cartridge` No. 2 is then pla-ced between the pawls 'n2 m and held by the upper parts of the t lait-ti. 4 charged the main breech-bolt is withdrawn, .and by this the aboveinentioned 'cani p moves f (See Figjl'.) After the rifle is disP the upper ends ofthe levers'o'o, and consepewls from each `otl 1e1 The cartridgeh'o is pushed upward by thev subsequent- ,cai-1 tridges and into the chamber. During thisoperation the cartridge lo. is caught by the lower arms of the pawls and prevent-ed from being further pushed forward, so as to'a-rrive vpau'ls in their position Aand of'an arm, m2, fixed tothe spindle. two parts ym and 'm2 are connected together on the further movement of. the pawl entirely between theflatter, and-,beheld by the upper arms until themaiu breech-holt is opened again. The motion of the pawls thus causes the cartridges to'enter the chamber consecib' tively. In orderto stop the repeating nicchanisni, stops of any description can be applied in oued irection by a spring, and in the other directionby inserting m2 into Im. The paw] in. may turn, therefore, in one direct-ion independently of .the spindle fn., and has to` overcome onlythe pressure of the spring t. This construction is necessary in order to allow themaga-zine to be filled'. The loading of 'the riiie takes place throughthe chamber'when the supplemental breech-bolt is opened. For
oi' the 4 aliove-described construction, yield and let the cartridges pass into .the-inagazine.
Even when'th e repeating device is disengaged, which position'cf the pawls is shown in Fig.
this purpose the cartridges are pressed between the pawls m m, which, in consequence IOO 17, it Awill be possible to fill the magazine, as
the lower arm of the pawl can be bent backi ward, owing to the arrangement of the sp'ring this yielding permitting the cartridges to be introduced. f
The improvements in the barrel of our new fire-erin, consistin surrounding the same with a steel tube, 15, in such a manner that anvr an'- nular space is left throughout the whole length of the barrel between the barrel A and the steel tube, as shown in Fig. l.v Thesteel tube B is screwed to the fore ond 'offther fclosing.-
socket, and ily-this means a solid connection. is 'formed at this point between the barreland the surrounding steel .tube The mout-h of the barrel isy loose ina casing, g", which is soldered in or ixed' by any other means te the fore end .of the tube-Bj. armis placed on' `th'e"c at if, .and the tube supported at this l*point by a ringJL, placed iu the interior of the tulle l e sight 'of the fireland surrounding the barrel. This ring 7), "is provided withl recesses l L', as shownin Eig. 2, so as to establish' a communicationbetween the annu ring 71.
j hollow spaces ,at bothv sidcsiof vthe the 'tube is provided mber'of openings, k
The arrangement of the tube B has for'its vpurpose (a.) to prevent any soldering on the barrel; (bito prevent any iexre of the bai irel produced by external causes; (c) to avoid furniture.
stock when this has 'become wet;` (d) pre-- venting, or at. least reducing, the 'danger to' which the'personis exposed in case the bar.- rel should burst by accident; (e) avoiding the undulation of the hot air surrounding the barrel and heated by the same, which undulation renders aiming extremely difficult.
The openings lc k' a',arranged on the lower side of t-he tube B, have for their purpose to lead away the heated air and to cause-'the air to circulate. f The caps Z l' Z serve to prevent the rain from penetrating through the said openings.- In lieu of the caps l ZY, any other suit-able .contrivance may be applied. It is obvious that when necessary any number of rings vl may be employed to support the tube P. The casing may also be provided with recesses, like the ring i', in order to produce a better circulation of air. It is very essential in this construction that the tube B should be connected to the barrel A only at one' end. lf. both the endsof the'tube (i. e., the mouth of the tube also) be screwed to the barrel or secured to the same by any other tubular chamber of the breech-piece by' means means,-the barrel A would bev curved in its middle part after having discharged a small number of shots, owing to the greater and norerapid extension of the barrel A in comparison with t-he tube B, which is not' heated at all, oronly to a small extent. The lastmentioned circumstance renders this construction particularly fit for magazine-rifles, the barrels of which become heated after a short use to such an extentthat'the rifleman cannot touch it with the naked hand.
. llerctofore a cap has been attached to the of a screw tapped into the end of the breechpiece; but this screw has no t-appets.
Having now particularly described and ascertained the nature ot' this invention and in what manner the same is to be performed, we declare that what we claim is l. breech-bolt S, of the firing-pin a and a nut, b, secured to the end of the tiring-pin, and having a flange lying againstthe endv of the breech-bolt, said flange having .lateral tappcts h b,engaging the supplemental breechbolt, substantially as shown and described.
