GUN-MUFFLER.
detached from the gun. Fig. 2 is a bottom "iew of the muffler shown in Fig. 1. Fig. 3 is a front end view of the anufller. Fig. 4 is a rear "end view of the muflier slightly modified by having its clamping lever on the reverse side to where it is in the other views. Fig. 5 is a detail view showing the plug of one of the valves letting out the gas. Fig. 6 is a longitudinal central vertical section of the mufiler exposing the end of the gun barrel clamped in it, and two of the valve plugs in place while a thirdplug is removed.
Referring to the drawing by reference numerals, 7 designates the muzzle or front end of the barrel of a gun, say a rifle or shot gun. Upon said end is placed the rear end of a cylindrical shell 8, which has an internal collar 9 adapted to limit the forward insertion of the barrel 7; it also has a downward slit 10 forming two cheeks 11 which are drawn or clamped about the barrel by a cam lever 12, fulcrumed to the head end of a screw 13 which is passed through one cheek and threaded into the other one so as to enable the cam to be properly adjusted against the cheek nearest to it.
The front end of the shell 8 is closed by a wall 14 having an aperture 15 and a sleeve 16 extending some distance inward from the wall. The inside diameter of said sleeve and aperture is slightly larger than the bore 17 of the gun barrel, so as to permit the bullet to pass out of the mufller without letting more gas than necessary escape from the muffler at said aperture 15.
Along the lower side of the mufller I provide a suitable number of gas outlet tubes Specification of Letters Patent.
Patented June 22, 1915.
Application filed September 30, 1914. Serial No. 864,241.
In each of these tubes is av screw thread 19 receiving the outer edge or top of a deep thread 20 of a plug 21, whereby a spiral duct 22 is provided for the gas of the powder to escape through so slowly that the report of the explosion is thereby deadened to such a considerable extent that ordinary game will not be scared nor will. the operator have the unpleasant feeling of the usual loud report of firearms. Each plug 21 is provided with a notch 23 for a screw driver to engage when screwing the plug into place and also for screwing it out when the spiral duct needs cleaning.
What I claim is 1. A gun muffler comprising an elongated shell having at one end means for securing it upon the end of a gun barrel and at the other end an outlet for the bullet, and
around said outlet :1. rearward sleeve extending some distance into the shell, said shell also having laterally disposed spiral ducts for the escape of the gas of the powder.
2. A gun muffler comprising an elongated shell having at one end means for securing it upon the end of a gun barrel and at the other end an outlet for the bullet, and around said outlet a rearward sleeve extending some distance into the shell, said shell also having laterally disposed spiral ducts for the escape of the gas of the powder, said spiral ducts being formed by lateral tubular projections on the shell and plugs threaded therein and having threads so deep as to form a permanently open spiral duct about each plug. 1
. lower side a series of depending internally 18, of which I have shown only three but in the practice about five of them are employed.
threaded tubes, a removable screw plug threaded into each tube and having its outer end provided with means fortaking hold of in turning the plug, the'threads of said plug being 'deep enough to form permanently open spiral ducts, for the purposes set forth.
In testimony whereof I aifix my signature, in presence of two witnesses.
