UNrrn FREDERICK I. JOHNSON, .orrI'rCHBUn rivmssacnu'snrtrst` UTOMATIC PISTOL.

To alt' whom it may concern:

Be it known that I, FREDERICK I. JOHN- SON, a citizen of the United States, residing in Fitchburg, in the county of Worcester and State of Massachusetts, have invented an Improvement in Automatic Pistols, of which the following description, lin connec# tion with the accompanying drawings, is a specification, like letters'on the drawings "said breech block being connected with an inertia member or recoil piece, which is contained in a chamber above and parallel to the barrel, the breech block and the inert-ia member being formed in a single piece. The

breech block normally lies over the magazine which is contained in the handle, and is thrown back by the recoil to expose the top of the magazine `and allow a newv cartridge to be forced up in front of thebreech block to take the 'place of the spent shell which is ejected througlli an opening in the side of he new cartridge is' then pushed into the barrel in front of the breech-block by the action of a spring which acts on the recoil-piece to push it forward. The hammer, which is pivotally supported behind the breech block, is provided with a spring and is arranged to be operated by the trigrer through. the agency of a push rod whlh extends from an abutment on the hammer forward to the trigger,` the said trigger acting on said rod to push it back, thereby cooking the hammer, the connection between the push rod and the trigger then being broken so as to allow the hammer to operate. The push rod is not connected with the hammer, so that in the recoil movement the .hammeris free to move independently of any. movement of the tri ger or push rod, and merely vfollows the reechblock in both directions.

Figure l is a side elevation, partly in section, of a pistol embodying theinvention; Fig. 2 is a similar` view showing the parts in the position they will reach at the end of the recoil movement.

l ".Ihe breech'blockc, which contains the tiring pin a2 to lire lthe cartridge contained recoil piece'or inertia vmember o which is located above the'brg'eech block and contained in a chamber c2 above'and parallel with the barrel. The'sad inertia member or Arecoil piece, 'as' it will be called hereinafter, is acted upon bya spring o3 located in anfextension of the chambery behind the -recoil piece, there being also an external linger piece c4 by which the recoil member and the breech block may be pulled back to allow the first cartridge to pass from themagazine into the space in front of the breech block and thence into the barrel, when the breechblock is moved forward by the spring. The magazine d is located in the grip or handle d2 directly below the breech block a, so that when said breech block isdrawn back by hand or forced back by the recoil, a space is afforded for the topcartridge which is then pushed forward into thel barrel through the action ofthe s ring c3 which restoresl the recoil piece andlbreech block to their normal position. The hammer e is pivotally suported at e2 below and at the rear of the iireech block and is provided withan engagn rod f which in turn is acte upon by the trigger g. The push rod f is not connected with the hammer, but is meely held by a suitable guideway inengagement with the portion e3, so that the hammer is free to be in the recoil operation. y

The trigger g is provided with a tripping member g2 which engages the front end of the push rod f,.so that when 4the trigger is pulled', the said push rod is forced back throwing the hammer back into tirin disengaging the tripping member g2 `from the push rod f, thereby releasing the hammer to explode the cartridge. y

The recoil of the explosion throws the shell back, carrying with it the breech block a and the recoil piece o until the Ishell comes into line with a lateral opening through the frame of the pistol, (see Fig. 2,) and in its backward movement is acted upon by an ejecting member in the-usualway. The

space for the inclosed cartridge which is 'pushed up by the spring in the'magazine, and thengforced forward into the barrel by in the-barrel b' is directly connected with al ing portion e3 to be acted upon by a push spent shell is thus thrown out, leaving a moved back independently of said push rod P0 sition, the final movement ofthe trlgger the forward movement of the recoil piece through the operation of the spring c3. The pistol is thus automatically loaded ready to be red by the next movement of the trigger which cocks and releases the hammer. 1aims:

1. In an automatic pistol, the combination with the hammer; whereby thetri'gger is caused to cock and release said hammer; a recoil-operated v-`extracting and loading device consisting of a movable breech block havin an oifsetextended portion, said breech lock and said extended "portion together constitutinga recoil piece; a tubularv guide-way for said extended portion parallel to the barrel; and

t a spring located in said guideway behind the extended portion'.

2. In a pistol, the combination with the barrel; of a tubular guide-way located above l -a spring operatin of the trigger; means said barrel; a recoil piece comprising a breech block and an oiiset vguide portion, said Aguide portion being located in a tubular guide way above the barrel, and the breech block extending downward therefrom into alinement with and behind the barrel; directly on said guide portion; a pivotal y supported hammer behind the breech block; a push rod acting on said hammer, but not connected therewith; and a trigger to act upon said push rod to cock the hammer and release the push `rod when the hammer has been cocked.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
