Specification of Letters Patent. Patnfed Aug- 2Q, 1922. Appiication flied July s, 1am. serial No. 309,443.
(GRANTED UNDER THE PROVISIONS 0F THE ACT 0F MARCH 3, 1921, 41 STAT. L., 1313.)
T 0 all whom t may concern:
l. Be it known that l, NICOLAS PIEPER, a subject of the King of Belgium, -7 Rue Bonne- Nouvelle, in Liege, Belgium, have invented certain new Improvements in Automatic Pistols (for which I have filed applications in Belgium, Dec. 27, 1913; France, June 6, 1914; Spain; June 15, 1914; Austria, July 16, 1914; Hungarygluly 16, 1914; Germany, June 22, 1914; Holland, Feb. 23, 1916; Great Britain, May 27, 1919), of which the follow -ing is a clear and exact description.
i The subject of this inventionis an automatic pistol which can be taken vto pieces, comprising a barrel completely distinct and independent from the receiver, which forms part of the stock.
l The `accompanying drawing shows, by way of example, three alternative arrangements vor' such a pistol :4
\ Figurevl is a longitudinal section of the first arrangement;
(Figure l);
Figure 3` is a section through B-B (Fig ure `l);
` F igure4 is an outside` view of the pistol; Figure 5` isan elevation View `of the'stock alone;
Figure 6 shows a longitudinal section of the second arrangement;
Figure 7 is a section through C--C (F igure 6 i Fig)ure 8 is a `section through D--D (Figure 6); Figure 9 is an outside view of the pistol; Figure 10 is a longitudinal section of the third arrangement;
- l`l`igure 11 isa front view of the barrel.
- The arm consists' of the stock 1, therear top part of `which 2 4orrnsthe receiver, in whichlthe bolt 3 works in the'well known manner This bolt'3 contains the firing pin 4, acted upon by a spring 5, which rests at its other end on the bottom of therecever 2 or rearwall offstock 1. 'y
Thebarrel 6 presents at its lower part the l two brackets "7 and`i8, through which it is i secured on the stock 1.
shown, the rearbracket 7 engages on a Xed 9, whereas the front bracket 8 seizes the VIn the example -front edge or" the stock 1; this bracket 8 provides also' a housing for a locker 10 which partly engages in thestock 41 and thus prethis chamber 12, and in front on the head of the rod 14 which passes through the back wall 13 and is secured to the bolt 3. In the arrangement shown,'the rod 14 is screwedin 'a lug 15 provided on the bolt 3, `wliichlug 'can travel backward an-d forward-in the upper part of the receiver 2. ,v
The receiver 2 1s provided with longitudinally extending slots 1 6 and slidably mounted inthese slots are longitudinally extending members 17 connected Atogether at their'forlward ends and inl advance of the bolt 15 by across piece, this crosspiece being perforated for the passage of rod 14. The mem- Figure 2`is a cross section` through A-A bers 17 are connected together at their rear ends of which are pivotally connected to members 17'so `that it may be swung upwardly to disengage the rear wall of the receiver'to permit the barrel andbolt to be removed together, that is without unscrewing the rod 14. The side surfaces of the U- shaped piece 18 are ribbed or knurledso that this member may be lirmly gripped by the fingers to work the bolt by" hand to cock the pistol preparatory to liring the first shot.
To take the arm to pieces, it is therefore only necessary to raise the stirrup 18, release the locker 10 by pushing it upwards and pull the barrel towards the front.
'The `arrangement of the arm shown in Figures 6 to 9 is similar to the above. In it "ceiver and xed on the front part of the the length of which corresponds to' that of l1 the stock and which carries on itssides the tvvo projections19 Which slide in the lateral slots 16 of the receiver 2 and enable thearm to be Worked by hand.
The bolt 3 contains the liring pin 4L, the spring 5 of which restsat the rear on a partv 20 of the receiver 2; This part 2O is sur-` y rounded by the bolt 3 which is grooved or slotted longitudinally at its lovver part (Figures6-and 7).4 i ,I
The detent mechanism may be of any convenient type in the example shown, it kcon-l sists of va tu-mblerv21 which lis acted upon by the rod 22 of the -trigger 24h The rear end of the rod 22 meets theA inclined face l23 of the stock 1 vvhen the trigger is pulled, 'which brings about the-release oitumbler 21 `from rod 22, and prevents cont-inued vdischarge of the pistol. l 'o s y .r
.In the case of Figures to 9, thebafrrel .also presents underneath the tWo lugs 7 and 8;the rear -ilug 7 engages with a fixed pin 9,r
, vvhilst the liront lug 8 is crossed by a screw v2.7 provided, forthesake of 'facilitatingthe if .dismantling and assembling, with` a lever Y '25 easily Worked by hand.j f f-Theejector consists of a. rod 25 slidably mounted in a Vtubular recess in the forward `end Aof the bolt 3, this recess being inclined oted and ejected through the slot 16 oppo-v site. A
yin the receiver 2 abovethe bolt 3 and behind the `lugabove thesaid bolt. In this alternative arrangement, the barrel 6 is no longer 4surm'cmnted iby the'chamber 11 but by a mere f .strip 28 offre'duced Width. i
v-ascertained the nature olirny said invention,
yIhe barrel '6 which is applied against the front face of the-re'ceiver2 is 'secured tov the stock. kf1`by Va similar arrangement to those `previously described, which lpermit-s of the pis'to-l being-easily taken to pieces. i,
order'to prevent the bolt 3 from `being thrust :EorWard by the Tetu-,rn spring after lthebarrel 6' Ahas been removed,fa locking de- -vfi'ce 29 isf-provided, which enables the lbolt 3 to be locked on thest-ock 1, in the receiver 2such1lfockin'g idevi'ceconsisting, for instance, off a liattened or notched to' the. safety vvlock arrangement.'l
` Having nowr'zpanti 'larly described land and in what manner the same is to be performed, I declare that'what I claim is:l
1. In an automatic pistol, in combination,
In the arrangement shown inFigu-res 10 and :11, the bolt-return spring 12 is housed a stock having avreceiver therein rfor a re- 'ciprocable bolt,'said receiver having an open- Y ing in its forward end for the insertion or Withdrawal of the bolt and having longitudinal slots in its side Walls, a barrel removably secured to said stock in advanceof said receivena reciprocable bolt in-said receiver,
elements movable with said bolt and extending` latterly throughsaid longitudinal, slots, and a lockingy member connected to one of said elements* and l .adapted to engage the kstock-When the barrel is removed to prevent the esca-pe" of' thevbolt -trom Ethe receiver, said member being manually movable relatively to said bolt andstock, to permit the bolt to be 'removed' from .said 'receiverA 'zv 2.".In an automatic pistolgi-n combination,
