Anfr'or MAKING BAnnELs. f
To all whom t may concern.' 7Be it known that I, THOMAS F. MOORE, a United States, residing at New York city, in the county of New' York and State of New York, have invented certain new and useful Improvements in the; Art of Making Barrels and I do hereby defull, clear, and eX- act description of the invention, such as will" enable others skilled in the artto which it` make and use the'same. The object in view is the improvement of etallic barrel makingv by the simplification o f procedure and the enhancing 'of the value of results by utilization of certain novel stepsl and combinations of steps in the process vof forming a 4metallic barrel as will in part become apparent and in part will hereinafter be particularly ointed out.
To facilitate a complete and eas ly-underthe process, reference willbe had-to the details disclosed in thev accompanying drawings, in w ich .Figure v1 is a sectional-elevation of a bar rel -completed by the practising of the imstructures will be set proved process. Fig. v2 'is'an enlarged' detail section' through a fragment of .the median or connectingring prior to bending of the groove-forming flanges. Fig. 3 is an en-` larged, detail, a portion of the interlocking ianges and contiguous 'parts prior; to the interlocking of the flanges. Fig.4 4 -is a similar view of .thev same just subsequent to the interlocking of the flanges. Fig. 5 is a similar view ofthe same after the final `step of. flattening the interlocked joints has been perfected. Fig 6 is a sectional perspective of a vfragment of o ne of the chime plates. Fig. 7 is a view.lv similar to Fig. 5 of the structure with a packing incorporated. Y
As the steps of the'improved process will best be understood by a detail description of the structures seen inthe drawing, such forth' specifically. Referring to the drawing by numerals, 1, 1, indicate half sections of a barrel, each preferably formed from a sheet of metal" stamped up into substantially the form of a Specification.

to form approximately one-half of a complete.barrel. Each bowl-shaped 'section is formed at one end 2 which forms a head of the 2 has -its `edge formed which presents 4. v Flange 3 is formed preferably by stamping during the ferred.
As "seen in Fig. A2. the ring 4 is formed providing edge portions having curvedsurfaces 5, 5., and intermediate, longitudinal flanges 6, 6. The plate having been-rolled in this form while `still straight-, is then further rolled to turn the flanges 6 to form longitudinal edge grooves 7, 7,
sui-nes the form of a ring, and the ends are grooves 7 open axially toward the ends of The resulting ringstructure is the manner indicated in Fig. 3, the parts being moved axially together, so that the grooves 7 bodily reoeiveanges 3 and the rounded edges of the s flanges 3 by being crimped over flanges 3, as
forming of thebody of the 'section 1, or subsequently thereto as pre-l and the plate is then bodily ,i curved, preferably by rolling, until it as-` sections formed by the flanges 3. The curved surfaces 5 are then by `being rolled, until the parts assume the form seen in Fig. 4, and then the joints are rolled to flatten the Vinterlocked. flanges to condition seen in Fig 5,
completed, the oints between sectionsl and ring 4 being absolutely tight and non-leak# liable to separate even under ing capacity of' these interlocked joints is particularly valuable since in -use the middle portion of a barrel is usually subjected to maximum strains. k-
the main body of the barrel is' A bung-hole 8 is' formed in ringA: preferably after the complete assemblage, and a similar bung or tap hole 9 is formed in one Iof the heads. Holes 8 and 9 are threaded to receive threaded bungs, and, to give the requisite thickness for the threads in hole 9,l
an annulus 10 is preferably Welded to the head 2 at the point for hole 9, through which annulus, the hole 9` is formed.l
Chime rings 11, 11` are provided for thev barrel, and ,applied either before .or after assemblage of the sections with the median ring 4. Each ring 11 is formed froma barv rolled into the shape seen in Fig. 7, and then rolled to form a ring, the ends .being then welded to complete the annulus.- The ring is then applied over the outer end of the respectivevsection's 1, whether assembled with theouter parts or not. The edge portions of the ring are proportioned and shaped to respectively engage the head or bottom l'of the section and theside thereof, andsaid edge portionsjof the ring are secured to the `sections 1, and said ring,
section preferably by spotwelding.
The median or connecting ring 4 is preferably of thicker stock than the` walls of with the stifening effect ofthe crimping of the 4interlocked` flanges,A materially stifens' and greatly strengthens the barrel structure. f
For some uses where a packed joint isv preferred, packingI material, such as lead",
or other soft metal, jute or rubber-adhesiveI tape is placed between the rounded edgey of.' the respective section l and the base of the respective 4groove .7, by either being-appliedl -end of each section,
respectively toward to saidrounded edge'or placed in the groove, and the process of completingthe barrel is then carried out as above specified. r-fIh/ere'- sultin'g structure 1s seen in Fig.,` 7, wherein; packing 12 appears, and as this structure vis ring for 'the sections n er "ends-of the'sections, and fold-ing the vmaterialforming the outer wall of each groove 'over and across Ithe edge of the respective ret'urnliange and vaxially vbetween said flange and the body of the section. f,
