BREECH-LOADING SPORTING GUN AND THE MIANUFACTURE THEREOF.

Application filed October 17, 1921. Serial No. 568,064.

To all whom it may concern:

Be it known that I, BARON Rose, a subject of the Kingdom of Great Britain, residing at The Mount, Halesowen, in the county of W'orcester, England, have invented certain new and useful Improvements in Breech-Loading Sporting Guns and in the Manufacture Thereof, of which the following is a specification.

This invention relates to breech-loading sporting guns of the drop-down type, and comprises an improved method of enlarging and completing the breech end of the barrel or barrels, including the forming or securing of the lump thereon. The inven tion, although of particular advantage as applied to double-barrelled guns, is equally applicable to single-barrelled guns of the type mentioned.

According to the present invention, as applied in the manufacture of a doublebarrelled gun, the barrels are permanently secured together at their breech ends by means of an electric welding operation wherein steel or iron is deposited by the welding electrode, such electric welding operation being further utilized to fill in the space intermediate the upper faces of the connected breech ends of the barrels, to provide the side shoulder enlargements on the under faces of the same, when required, and when not formed on the barrels in the process of making the barrels, and to attach the lump centrally and longitudinally beneath and between said connected breech ends of the barrels.

As applied in the manufacture of a singlebarrelled gun, such electric depositing and welding operation is similarly utilized to provide the small central enlargement on the upper face of the breech end of the barrel, to provide the side shoulder enlargements on the under face of the same when required, and when not formed on the barrel in the process of making the same, and to attach the lump centrally and longitudinally beneath said breech end of the barrel.

In order that this invention may be clearly understood and readily carried into practice, reference may be had to the appended explanatory sheet of drawings upon which Figure 1 is an elevation in perspective of a pair of gun barrels having their breech ends secured together and completed in accordance with one form of this invention.

Figure 2 is a similar view of a single gun barrel having its breech end enlarged and completed inaccordance with another form of the invention.

Figure 3 is an elevation in perspective of a suitablerolled bar form of breech lump member for the double-barrelled gun.

Figure 4 is a sectional end elevation of the breech end of the pair of gun barrels secured together and to the lump by the electric depositing and welding operation.

Figure 5 is an end elevation of the same subsequently machined and finished.

Figure 6 is a perspective View of a suitable rolled bar form of breech lump member for the single-barrelled gun.

Figure 7 is a sectional end elevation of the breech-end of the single barrel as enlarged and secured to the lump by the electric (leposlting and welding operation.

Figure 8 is an end elevation of the same as subsequently machined and finished.

In carrying the invention into effect in the manufacture of the double-barrelled gun, the pair of gun barrels a a, see Figures 1, at and 5, are first adjusted in correct relative alignment and are temporarily secured in such alignment by means of clamps or the like (not shown) or by spot welding the barrels at their opposite ends. The breech ends of the barrels are then electrically and permanently welded together for the required longitudinal distance by steel or iron deposited therebetween by the Welding electrode, said electric depositing and welding operation being continued to fill in or partly fill in, as at 7), the space intermediate the upper faces of the connected breech ends of the barrels, to provide enlargements c 0 on the under and outer faces of the connected breech ends of the barrels if required for formation of the side shoulders, and to secure the lump (Z in position, said lump being advantageously of a rolled bar section. see Figure 3, with a suitably roughened or interlocking jointing edge e to facilitate the welding operation.

The breech ends of the pair of gun barrels a a as thus connected and enlarged are readily machined and finished to the required conformation, with the upper intermediate facef advantageously of a somewhat concave form, with the side faces 9 9 vertical or tapering slightly in a downward direction and flush with the upper and outer circumference of their respective barrels, and with the side shoulders h h in substantially horizontal alignment at right an les to the side faces of the lump d.

in carrying the invention into effect in the manufacture of the single-barrelled gun, see Figures 2, 7 and 8, the electric depositing and Welding operation is similarly utilized to provide the small central en largement i on the upper face of the breech end of the barrel a, to provide enlargements 0 0 on the under and outer faces of the breech end of the barrel if required for formation of the side shoulders, and to secure the lump d in position, which lump is again advantageously of a rolled bar sec tion, see Figure 6, with a suitably r0ugh ened or interlocking edge 6 to facilitate the welding operation. The breech end of the gun barrel a as thus enlarged and secured to the lump is readily machined and finished to the required conformation, with th upper central face 7, side faces 5] g, and side shoulders h, it, all as hereinb'efore described With reference to the manufacture of the double-barrelled gun.

In cases where the flats or. side shoulders h i1. are not required, or where they are formed on the barrel in the process of making the barrel, it is of course unnecessary to form the enlargements c c by deposit of metal from the welding electrode.

The electric welding operation as hereinbefore described provides a breech end for the gun barrel or pair of gun barrels of a particularly strong and rigid construction, and which is adapted for a particularly fine external finish.

What I claim as my invention, and desire to secure by Letters Patent is 1. The method of enlarging and assembling a breech end and lug which comprises the placing of said parts in adjacent rela tion and depositing iron or steel thereon by an electric welding electrode to unite said parts and provide an enlargement thereon.

2. The method of enlarging and assembling breech ends and lug which comprises the placing of said parts in adjacent relation and depositing iron or steel thereon by an electric welding electrode to unite said parts and provide an enlargement thereon.

3. A gun breech end comprising a barrel breech. a lug arranged in adjacent relation thereto and a deposit of iron or steel electrically welded to and uniting said barrel breech and lug and providing an enlargement thereon.

4. A gun breech end comprising a pair of barrel breeches, a lug arranged in adjacent relation thereto, and a deposit of iron or steel electrically welded to and uniting said barrel breeches and lug and providing an enlargement thereon.

In Witness whereof I have hereunto set my hand.

BARON ROSE.
