ATTACHMENT FOR BARRELS OF FIREARMS.

SPECIFICATION forming part of Letters Patent No. 658,934, dated October 2, 1900. Application filed January 5. 1899- Serisl No. 701,240. No model.)

so construct the attachment that it will materially modify or entirely prevent the noise made when a weapon is discharged, and will also act to suppress the smoke almostentirely when black powder is used.

A further object of the invention is-to attain the ends above set forth without impairing the power or accuracy of the weapon.

The invention consists in the novel construction and. combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a rifle and the attachment applied thereto. Fig. 2 is a longitudinal section through the attachment, drawn on a larger scale than in Fig. 1, and also a longitudinal section through that portion of the barrel to which the attachment is applied; and Fig. 3 is a transverse vertical section taken practically onthe line 3 3 of Fig. 2.

-A represents a casing,which is usually made oval in cross-section, as shown in Fig. 3. This casing is provided with a collar 10 at the rear end of its body' portion, and the said collar is adapted to be screwed upon or otherwise attached to the forward or muzzle end of the barrel A of a gun, as shown particularly in Fig. 2. At the rear lower portion of the body-casing A'a tubular extension 11 is formed, which is usually circular in crosssection, but may have other cross-sectional contour. The extension 11 from the casing is adapted to extend rearwardly beneath the but certain portions of this expansion-chamher-are shut off, as will be hereinafter stated.

- "-The body-casing A is adapt 50 receive cap B, the cap being at the forward or delivery end of the casing, and this cap is adapted to slide within the body-casing and is held in engagement therewith in any approved manner-as, for'example, through the medium of spring clips or tongues 13-as shown in Figs. 1 and 3. The inner face 14 of the cap B is inclined, the inclination being from the upper edge downwardly and forwardly, and the innenface of the cap is open from a point at or near its bottom to a point near the top. The upper portion" of the inner inclined face of the cap B is provided with a deflecting-plate 15, and the-said deflecting-plate has an opening 16, the center of said opening being in longitudinal alinement with the axis of the bore A' of the barrel.

Immediately forward of the opening 16 in the deflecting-plate and at the forward upper end of the cap a chamber 16 is formed provided with aninlet 17, the center of which inlet is in a plane with theicenter of the axis of the opening 16 in the deflecting-plate and the axis of the bore A of the barrel. This alineinent of the openings 17 and 16 with the bore of the barrel is in order that the bullet discharged from the barrel may pass through the said openings 16 and 17 and out through the chamberlfi without interfering in the slightest degree with any of the mechanism IOO gun, and a valve having bearing normally against thedeflecting-plate, the said valve beingforeed to 'a seat at the inlet of. the said chamber, by the action of the gas accumulated in the barrel and back of the said valve and deflecting-plate, after a bullet has been discharged, as described.

p 6. The combination with the barrel of'a ggun, of a casing attached to the'muzzle of said barrel, a cap secured in the forward endof' the casing and provided with an inclinedde- *fiecting-plate having an opening therein in line with the axis of the barrel, a chamber forward of the deflecting-plate and provided I 5 with an inlet-opening also in line with the bore of" the gun-barrel and formed with a valve-seat'and a spring-pressed valve normally resting against the deflecting-plate and adapted to be forced against said valve-seat,

; substantially as described.

7. The combination with the barrel of'a gun, and a casing attached to the muzzle of the barrel and having a tubular extension at -t-h'erear lower port-ion provided with a remov- 2 5 able'closure at its rear end, of a cap remov ably seen red in the forward end of the casing, the inner face of said cap being inclined from the upper edge-downwardly. and forwardly and the said inner face being open from a 0 point ator near its bottom to a point near the tom-an inclined deflecting-'plateat the upper --port ion of the inclined inner face of the cap, the said plate having an openingin its lower v dge in longitudinal alinement with the axis of-theabore'of the barrel, a chamber formed at the forward upper end of said cap and forwardof the plate, the said chamber being pro- 7 jvided with an inlet in its inner wall in'line with theopening in the plate and the bore of 4othe barrel, theinner wall of said chamber being inclined and having a flange formed thereon around t-he'inlet-opening and constituting a valve-seat, and a pivoted and spring-pressed valve nrmally resting at its upper end against the lower portion of the deflectingplate and having an opening at its upper edge forming with the opening in the loweredge of the deflecting-plate, a passage for the bullet, the said valve being forced to its seat at so the inlet-opening of said chamber by the action of the gases after a bullet has been dis- :ch-arged, the front of said'cap below the chamher having an opening provided with-a removable closure,'for the'purpose set forth.

8. A casing arranged for attachment to the barrel of a gun and provided with a gas-con'- densing' chamber, and a cap removably secured in the forward end of said casing and provided with a chamber having an opening in line with the axis of the bore of the gun and forming a passage for a bullet, a. valve pivoted in said cap and operated by the gases tocl'ose the outlet for the bullet immediately after the escape of the bullet, the said cap being provided with an opening in its front .below the said chamber, and a closure for said opening, substantially as described.

9 A device adapted to control the noise of the explosion of a'charge and prevent the escape of smoke from the muzzle of a gun, the said device comprising a casing arranged for attachment to the muzzle of'a gun the casing being provided with a passage-way for a bullet, a valve for closing said passage-way, a spring for normally holding said valve open, and a deflecting-plate for turning the flow of gas toward the valve, the valve being carried to closing position by the gases.

10. A casing for attachment to the muzzle of a gun, a cap removably secured in the forward end of said casing and having a valveseat with an opening for the passage of the bullet and a valve carried by said removable cap and free to swing, the said valve being normally held in an open position, and adapted to be moved by'the action of the gases to a closed position,.substantially as described.

11. A casin g arranged for attachment to the muzzle of a gun, a removable cap fitted in the forward end of the casing and having a valve- 0 seat with an opening for the passage of the bullet, the axis of said opening coinciding with the axis of the bore of the gun, a valve carried by said cap and free to swing to close said opening,"a spring for normally holding said valve in the open position, and a deflecting-plate carried by the cap and arranged to deflect the gases toward the valve, the said valve being closed by the action of the gases, whereby the said casing receives and confines for a time the gases resulting from firing the READE moon wrsnmc'ror.
