FIREARM.

. Specification of Letters Patent.

Application filed April 1],, 1910. Serial No. 554,593. Z

Be it known that LARTH R I. Rissnn, a citizen of the United States, residing provement'in Firearms, of which the fol- ;lowmg s a specification.

,Mszinvention relates particularly to pocket fire farhis of the character set forth in pat- .and my primary objectis'to having? plifyingof the manufacture and -the imcomprises a barrel ent to-lVebber,N0.'788,866, May 2, 1905;

fire-arms certain details of construction, for the purpose thereof the sim provenient of the operation of the fire-arm s. The inventionis illustrated in the accompanying drawing, in.'whichgure 1 represents a side elevational viewa fire-arm constructed in accordance with m improvements; Fig. 2, 'a sectional view ta e ternally-threaded at the reduced portion; a v cylindrical frame B having an open internally-threa'ded front end screwed-on to the redue'ed rear end of the barrel; :1 breeclr piece C screwed into the' cylindrical member 13 and located near the front end thereof; a

plunger D provided at the center of its front face with a firing-pin 1; a coiled spring I) 5 project.

seated a bore which extends into the rear end of the plunger D and having its rear end bearing against the rear end or cappiece 2 of the cv'lindrical member B; audai'ing E slidably moimted on the barrel and equipped with rearwardly-extending springarms 3 which are provided near their rear ends with slots, or perforations, 4 adapted to engage catches, onprojections, 5 which project laterally from the plunger D.

The tubular frame B is provided with longitudinally-extending lateral slots 6 through which the arms, or catclmnembers,

Said catch-members 5 are carried by a ring 7 which is secured on the reduced front-portion 8 of the plunger D at the base of the firing-pin 1. In assembling at Chicage, in the county of Cook and State of Illinois, haveinvented a new and useful Imimprove said tions in which the s'lots 4 in the rear of said portions the arms are rear end of the tubular frame B the parts the,ring 7 is introduced through one of the slots 6, the plunger D is inserted from the rear of the tubular member B. and I the front end of the reduced portion -8 of the plunger, which projects through the bore in the ring-7, is upset or riveted against the frontsurface of the ring, by means of a tubular punch. \Vhen it is desired to re tract the plunger the ring E is' moved forwardly to the position shown in Figs. 1 and 2 to allow the slots 4 of the spring-arms 3 to become engaged with the catch-members 5 carried by the ring 7. To facilitate this.

engagement the arms 3 are bent or inclined inwardly, as indicated at 9. The arms then extend parallel with each other at the porbent .orinclined inwardly, asindicated at 10, so that the extremities ofthe arms will enter the slots 6. The extreme end portions of the arms are preferably curved outwardly slightlv as indicated atll, affording cams adapted to spread the arms}; and release the plunger after it has been fully retracted.

Between the breech-block C and 'the rear end of the reduced portion of the barrel A is a space 13 adapted to accommodate the are located, and

flange of the'cartridge 14; and said breechblock is provided with a central perforation 15 adapted to receive the firing-pin, said perforation being counterbored at the rear portion of the breech-block, as indicated at 16, to accommodate the projection 8 of the. plunger and base portion of the firing-pin.

As has'been indicated, the rear end 2 of the tubular member B may comprise a sheetmetal cap whose flange is adaptedto embrace the rear portion of the tube, and which may be secured in place by a prickpunch operation. Over the cap 2 and the y I is slipped a rubber handle, or knob, F. The flange of this member is provided with'lateral slots 17. The manner of use may be stated briefly. The barrel may the frame to permit the insertion of a cartridge and when theparts are againjoined together the flange of the cartridge is clamped firmly between the breech-piece and the rear end of the barrel. In thefiring operation, the piece is held in thehand with the handle F resting upon the palm of the. hand and the barrel lying between the index and middle fingers, by means' of which the be readily unscrewed from D rea'rwa'rdly against its spring.-

extremities of the spring arms 3 impinge take vaim.

upon the frame at therear ends of the: slots 6, the spring-arms are spread apart, thereby releasing the plunger, which then flies forward under the force of its spring and produces the explosion. The piece (exaggeratedly illustrated) is of smallenough size to permit it to be handled readily in the manner described. -Moreover,"the form andsmall size of the piece permit it to be carried readily about the person and to be carried oi drawn unnoticed incase of emergency. The piece is, of course,,intended for use at short range Where it is unnecessary to In the improved'construction, the plunger is, provided with a comparatively long contact with -the bore of the tubular frame, the sprlng is properly housed, and there is no 1pportunity for the spring-arm's 3 to engage e'main spring in any detrimental manner. Moreover, the spring-arms 3 may be produced in a stamping operation, in which 0 eration the slots 4 maybe formed. Also, t e piece 7' may be stamped from sheet-mtal and may be readily applied.

What I regard as new and by Letters Patent is-f v 1. A fire-arm comprisin a barrel supported there y, a spring-held desire to secure plunger in said frame equipped at its front end witha seat for a ring, a ring secured on said seat and provided with lateral injections extending through lateral slots in said .tubii lar frame, and a slide-ring encircling said extending spring-arms having extremities barrel and provided with rearwardly .tering said slots and having a tubular frame,.
