RICHARD MORRIS, OF BLAOKHEATH, COUNTY OF KENT, ENGLAND.
AUXILIARY BARREL FOR Guns.
SPECIFICATION forming part of Letters Patent No. 351.333, dated October 19, 1886.
Application filed June 29, 1886. Serial No. 206,635. (No model.) Patented in Eng and March 8, 1886, No. 3,244.
To all whom it may concern,-
Be it known that I, RICHARD IVIORRIS, a citizen of England, residing at Blackheath, in the county of Kent, England, have invented a new and useful Improvement in Guns, of which the following is a specification.
My invention relates to guns of the kind known as quick-firing shell-guns, in which the charging, firing, and extracting operations are performed by machinery and it consists in apparatus and appliances whereby such guns can be worked for practice with miniature ammunition.
The object which I have in view is to save a large part of the cost which the use of fullsize ammunition involves, to avoid the necessity for the extensive ranges required when full-size ammunition is employed, and at the same time to give the gunners the same drill and practice in sighting, aiming, and serving the gun as they would obtain if full-size ammunition were used. For this purpose I fix centrally within the bore of the gun a small barrel, preferably similar to that of a serviceride, so that the service-cartridges can be used as the miniature ammunition. I provide a number of tubular blocks which correspond in size with the ordinary cartridges used for the weapon, each of these blocks being charged with a small rifle-cartridge,and I employ these blocks so charged for serving the gun. Each block is inserted in the usual way at the breech of the gun, has its small cartridge fired, and is then extracted just as the ordinary cartridges for the gun are dealt with; but the expenditure of ammunition is only that of the small car tridges with which the blocks are charged,and the range required is only that which is suited for the small projectiles.
Figure l of the accompanying drawings is a longitudinal section of the rear part of the bore of a quick-firing shell-gun, showing part of the small barrel and one of the tubular blocks in position. Fig. 2 is alongitudinal section of a part of the bore farther forward, showing the arrangement for fixing the small barrel centrally therein.
A is the small barrel, which is chambered out at the breech, as shown at (0 has fixed on it a collar, a fitting the coned part of the charge-chamber of the gun, has fixed on it,near its front end,a collar, a, andis screw-threaded at the extreme end a 011 this barrel is placed a coned sleeve, B, into the end of which a screws, and an internally coned casing, O, which approximately fits the bore of the gun, and is split along one side, as indicated at c. A ring, a, is put on in halves over the collar (6, and is secured by screws a to the casing O. The barrel'A, with the sleeve B and the casing 0 on it, is passedinto the bore from the breech of the gun until the collar a takes its bearing. Then by turning A round several times, its screwed end to acting in B as in a nut, draws B toward the rear, and this swells out the split casing O, causing it totake a firm grip within the bore. Thus the small barrel A is held firmly centered in the bore,presenting open at the breech its chambered mouth a The tubular block has a strong bottom, M, into which is screwed a steel chamber-tube, L, which externally fits into the chamber a, and internally fits the miniature cartridge that is to be used. To the bottom M is fixed, by screws or rivets,an inner bottom, m, to which is affixed the tube N,strengthened at the mouth by an inner lining, n. The tubular block M N is of the same shape and size as the ordinary cartridges used for the gun, except that it is made shorter, these cartridges being of such length as to extend to the coned part at a. A number of the tubular blocks M N being provided,each charged in its chamber-tube L with a cartridge suitable for the small barrel A, those charged blocks are dealt with in the same way as the ordinary cartridges which are used for the service of the gun.
I am aware that a rifle-bushing has been inserted in the breech end of a ride for firing small cartridges 5 and such, therefore, I do not broadly claim.
Having thus described the nature of myinvention, and the best way I know of carrying it out in practice, I claim- The combination, with a small barrel, A, fixed centrally in the bore of a quick-firing machine-gun and constructed with the chamber c at its breech end, of the tube N,fitted to the bore of the machine gun, and through scribing witnesses, this 15th day of June, A. D. which the small barrel passes, and the block 1886.
