To all william, may concern.'

Be it known that L HiRAM PERcY Mexm/I,V

a citizen ofthe'United, States, residing in the city of Hartford, in the State of Con necticut, have inventedcertain new and use# v ful Improvements in Firearms, of which the following isa specification, reference being had to the accompanying drawing,- forming a part hereof. This Ainvention relatesparticularly to -th means for securing silencers of devices for reducing the noise of discharge of firearms, upon the muzzle of shoulder arms and particularly of military rifies. It is necessary that such devices shall be secured in proper alinement and it is also desirable that they shall be capable of being secured, especially upon military rifles, without requiring any change in the-rifle, even such a change as the cutting-of a mutilated screw thread upon the Y forward extremity of the gun barrelto engagev a corresponding internal screw thread' in theneck of the silencer. Such a-means as that just referred to permits the silencer to be applied to the firearm and removed at will as is usually desirable in the case of a sporting riie, IWhile in the'case of a military riie it is now considered desirable that the silencer shall be in the nature of a permanent attachment, that is, `that it shallv be removable only for the purposes of repair or cleaning. lt is, of course, in all cases desirable that'the silencer shall beso secured as to withstand the tendency of the discharge of the firearm to separate `vit from the barrel. ,y j

It is the object of this invention, therefore, to provide a coupling device by which a silencer can be accurately and firmly` secured to the barrel of a firearm or gun without requiring any modification ofthe barrel. Such coupling may be either an integral part of the silencer or it may be formed separatel therefrom and adapted to be engaged therewith by a mutilated screw thread or other suitable connection.

The improved coupling comprises a sleeve adapted to lit upon the barrel, a split grip-v ping ring to encircle the barrel anda nut or internally threaded sleeve adapted torengage the threadedportion of the coupling sleeve and at the same time to clamp the f gripping ring tightly about the barrel.

Theinvention will be more fully explained hereinafter with reference to the accompaspec'ication of Letters ratent. Application filedv April 23, 1519. /V SerialA No. 557,238.

is a view, partly in vertical, longitudinal section, on the plane indicated by the line` 4 4 of Fig. 2, the silencer being shown as separably secured to the barrel. Fig. 5-.is

a detail'view in section on the plane indicated by the line 5 -5 of Fig. 4.' Fig. 6 is a detail view showing the coupling as an.-

'integral part o-f the silencer.

The rifie a shown in Fig. l is a military rifle of a well known type, having upon the forward end of its barrel b a band c 'which 'supports the front sight block al, the bleekl al being removable as usual. The blade e of the front sight is mounted in ythe block d as usual. ln the constructionshown, thecoupling,- hereinafter described, is adapted fo-r application'toa firearm having a front sight of the character referred to, but the l I invention is not concerned with the particular construction of 'the front sight nor `indeed is the existence of a front, sight abso-- lutely essential. to Atheapplicatitm of the Coupling.

' rl-lhe silencer f may be of any suitable cony struction. It maybe formed separately from the coupling sleeve hereinafter referred to. and'secured thereto by any suitable means, as`by screw threads, as shown at f' 1n Figs. 4 and 5, or it may be formed in one piece with' the coupling sleeve, as,` shown in `The coupling sleeve g is adapted to t upon the forward extremity of the barrel b. The fit should somewhatv closey for the sake of accurate alinement, but need not be tight.. .When that portion ofV the barrel which enters the coupling sleeve g bears the yfront sight, as is usually the case, or any other projection, the sleeve g is slotted from its rear end, as at g', so as to straddle the block, and at its rear end the sleeve is threaded externally, as at g2. Surrounding the barrel in rear of the sleeve g is a split gripwire b. Thfzgripping ring is preferably lping ring h, which may-be formed in two i or more parts heldv together byfaspring' when clamped thereon.

roughened internally, as at h2, in order that it may have a firm hold upon the barrel A clamping ring z' is formed to engage the coupling sleeve g, bein-g preferably screw threaded, as clearlv shown in'Fig. 4, and also formed to clamp the gripping ring h upon the barrel, preferably having an internal taper whichlcorresponds to the external taper of the gripping Y ring.

ring firmly upon the barrel and simulta` neously drawing the coupling sleeve home. The gripping ring is then anchored firmly to the barrel and the coupling sleeve is anchored rmly to the gripping ring and the silencer isv thereby held rmly in position. The tendency ofthe discharge of the gun is to draw the coupling sleeve forward, but the tendency of such movement is only to cause the gripping ring to grip the barrel more tightly and thereby to hold the silencer more iirmly in place.

It will be understood that the form and relations of the parts may be varied more or less to suit diiferent conditions of use and that the invention therefore is not limited to the precise details of construction shown and described herein.

I claim as my invention:

The combination with a firearm having a front sight block, of a' coupling sleeve for a silencer adapted to be slipped upon the barrel and having van interior shoulder engaged by the barrel to limit the movement of the sleeve rearwardly and slotted to straddle the front sight block, a split gripping ring adapted to encircle the barrel in rear of the sight, a clamping ring adapted to clamp the gripping ring upon the barrel and to engage the coupling sleeve and cooperating with the sight to prevent the removal Aof the coupling sleeve from the barrel.
