CCRRUGATED METALLIC BARREL.
Specification of Letters Patent. Patemtngd D em 1M1, 1191'? Application filed. March 12, 1917. Serial No. 1%,116.
To all whom it may concern:
Be it known that T, JAMES F. EA:roN,'a citizen of the United States, residing at Richmond, in the county of Contra Costa and State of California, have invented certain new and useful Improvements in Corrugated Metallic Barrels, of which the following is a specification. I
My invention relates to the class of metallic barrels, and more particularly to a metallicbarrel having reinforcing corrugations formed in the walls thereof.
The object of the invention is to produce a barrel which has the least possible weight for a given amount of strength and stiifness; and which can be manufactured at a A further object of the invention .is to provide a barrel of such a form that it can be easily handled.
My invention will be hereinafter described in its preferred form; but it is to be understood that changes, within the scope of the claims hereto appended, may be .made in the form and construction of the barrel, without departing from the spirit of the; invention.
With this in view, my invention will now be described, with reference to the accompanying drawings, wherein- Figure 1 is a side elevation of my improved barrel, the heads being shown dotted.
Fig. 2 is a detailed axial section, enlarged, of a portion of one end of the barrel, show ing portions of the body, the end, and the seam therebetween.
Fig. 3 is a detailed end elevation of the parts shown sectionally in Fig. 2.
The barrel comprises a body portion 1 and heads 2. The body portion 1 may have any suitable general form, preferably with a bilge, as shown, and is preferably constructed of a single metallic sheet, which, in the process of making the barrel, is rolled to substantially cylindrical form and its edges secured, as by welding. The body, as shown in the drawings, has three zones, namely a central or bilge zone 3, and end or taper zones 4. The end zones are formed w1th, and their taper provided by longitudinally directed corrugations 5, which, be-
ginning with the borders of the bilge zone,
are gradually drawn in to the ends, and this in turn gives the bilge to the barrel. The bilge zone 3 is preferably formed with circumferential corrugations, as shown.
ter-round cross-section, the convex side being outward; and the corrugations of'the flange 6 are extended transversely across this head to the edge of the central flat portion 7. The purpose of said bead 8 is two-fold; first, to add strength and stiflnessto the head 2, and thereby to strengthen and stiflen the entire barrel; and second, to enable the barrel to be easily and conveniently handled, for by thus depressing the heads of the bar rel, and providing this corrugated bead immediately inside the chime, said barrel may be easily grasped, the corrugations of said bead providing a good grip for the fingers.
The dimensions of the flange 6 and the bead 8 are relatively unimportant. In a barrel having a diameter at the head of twenty inches, I prefer to initialla make the flange 6 of the head one-quarter of an inch wide, and said flange may beburned, in the welding of the head and the end of the body, to one-eighth of an inch. The bead 8 in a barrel of these dimensions is preferably formed on a one inch radius.
The beads 8 of the heads constitute the essential feature of my invention. 0n account of the strength and stifl'ness imparted to the barrel by said bead, no outside band or ring is required to reinforce the chime. The barrel therefore comprises three parts only, namely the body and the two heads. The body can be formed at one operation, by rolling, and the heads each formed by one stroke of a suitably formed die. The welding of the seams then completes the barrel. Thus it will be seen that my barrel, in addition to having the maximum strength consistent with its weight, and being convenient to handle, is also comparatively in-' tudinally corrugated body portion, a dished 110 corrugations corresponding to and fitted rugations of said within the corrlfigated end of said body portion, and a sti ening outwardly convexed bead formed between the flange and the body portion of the head, said bead being transversely corrugated by extensions of the corflange.
2. A metallic barrel comprising a longitudinally corrugated body portion; and a 'dished head having a flat central portion,
and an outwardly turned peripheral flange corrugated to correspond to and fit Within the corrugated end of said body portion, and an outwardly convexed stifl'enin bead formed between said flange and sald flat central portion, said bead being corrugated transversely by extensions of the corrugations of said flanges.
3. A metallic barrel comprising a body portion, and a dished headformed with a peripheral flange adapted to fit within and be secured to the end of said body portion, said head having a stiffening bead formed as an annular outwardly convexed shoulder, of approximately quarter-round cross-section, etween. said flange and the. central portion of said head.
4. A metallic barrel comprising a longitudinally corrugated body portion, a dished head therefor, comprising a flat portion, and an outwardly extending peripheral flange shaped to fit within one end of the barrel, and a series of convexed beads connecting said peripheral flange with the flat portion of the head, the said flange having corrugations resting against and correspond ing with the corrugations of the body portion and said beaded portion having corrugations registering with the corrugations of the flange.
5. A metallic barrel comprising a body portion having a circumferentially corrugated bilge and longitudinally corrugated tapered ends; and dished heads formed with central flat portions and corrugated peripheral flanges corresponding to and fitted within the corrugated ends of the body portion, said heads having stiffening beads formed as annular outwardly eonvexed shoulders, of approximately quarter-round cross-section, between the peripheral flanges and the central portions, and said beads being corrugated transversely by extensions of the corrugations of said flanges.
6. A metallic barrel comprising a longitudinally corrugated body portion, a dished head therefor, comprising a flat body portion disposed within one end of the body portion of the barrel, an outwardly disposed peripheral flange corrugated to fit within and engage the inner corrugated surface of the portion of the barrel, and a series of finger engaging stiffening beads interposed between said flange, and the body portion of the head, said stiffening beads being formed by convexed outward projections corrugated transversely by extensions of the corrugations of said flange.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
