METALLIC BARREL.

SPECIFICATION forming part of Letters Patent No. 550,309, dated November 26, 1895.

Application filed December 27, 1894. Serial No. 533,062. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR WILZIN, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Metallic Barrels and Like Vessels, of which the following is a specification.

This invention relates to barrels and like Vessels of the class formed of two halves or a greater number of parts stamped, drawn, or spun from sheets or blanks of metal and united at their edges by a double-seamed,

'SWGEtlJGCl, or other suitable joint to form a complete barrel. Heretofore such vessels have been formed with inwardly or outwardly projecting corrugations or ribs intermediate of their ends and with two external hoops adjacent to the seam between their parts or halves and held in position by said ribs for protecting the seam and receiving the shocks to which such vessels are subjected in use. To fix such. hoops in position it has been necessary to strike or spin up a rib or projection at one side of the hoop after the application of the latter to the part of the barrel carry-. ing it, this being usually done befgethetwo parts of the barrel are seamedtogether, and to unite the two parts of the barrel when a folded or double seam is used for the joint it has been necessary to cut an aperture in the head end of one of the parts, through which could be inserted an arm carrying a resistance-roller for reinforcing the inner wall of the barrel against the pressure of the foldingrollers operating on the exterior to form the seam. Such apertures are subsequently closed by a disk soldered or otherwise applied to the head. In such devices the external hoops are inconvenient in use, increase the size of the barrel, and being necessarily some distance from the seam or joint do not afford sufficient protection for the latter. Should either hoop be distorted, its distortion is communicated by the part of the barrel carrying it to the adjacent seam, thus tending to impair the tightness of the latter.

Devices of the character described belong to the class of vessels in which the parts or sections going to make up the shell of the body are permanently or inseparably joined and detachably coupled to each other.

together and are to be distinguished from the class of metallic vessels in which the parts or sections of the shell are merely temporarily In the latter class it has been customary to outwardly flange the adjacent edges of the sec tions, place rubber or other packing washers between these edges to prevent leakage, clamp the edges together by outer sectional clamps channeled on their inner faces and taking over the flanges of the sections, and lioldthese clamps in place by screws passing through them and the rubber between the edges of the sections and screwing into an internal ring within the vessel. A second rubber or other packing washer or ring is in such devices placed between the internal ring and the inner faces of the sections at the joint as a further preventive of leakage. \Vhen not in use the parts of such vessels are uncoupled and'nested for shipment or storage, and when assembled and used their strength is dependent upon that of the outside clamps, which project beyond the normal belly of the vessel and thereby increase its bulk, and their tightness is dependent on the packing washers filling the spaces between the sections and between the internal ring and the latter.

My present invention aims to provide an improved construction for barrels and like vessels made of two halves or parts united by a joint or seam, to the end that such devices may be provided with a strengthening hoop or hoops without increasing their bulk and may be otherwise improved, simplified, and strengthened, while their manufacture shall be rendered more convenient and less expensive.

To this end in carrying out my invention I'provide such vessels with an internal reinforcing hoop or hoops and the shell of the barrel-body with indentations around its circumference engaging and holding in place the hoop or hoops, and in the preferred form of the invention I provide one such hoop opposite each seam or joint between the parts of the vessel and construct the hoop and vessel with reciprocal interengaging faces resisting separation of the respective parts of the ves- -sel, and construct the hoop with an annular vexternal groove receiving the folds of the seam uniting the two parts of the vessel, so that the seam does not project beyond the bilge or belly of the barrel.

111 the accompanying drawings, which show certain adaptations of my invention, Figure 1 is an axial section of a metallic barrel c011- structed according to the preferred form of my invention. Fig. 2 is a fragmentary section thereof on alarger scale. Fig. 3 is a view similar to Fig. 2, but showing a modification. Fig 4 is a similar view showing another modification, and Fig. 5 is a similar view showing still another modification.

Referring first to Figs. 1 and 2, let A A indicate the two barrel-heads, B B the two half bodies or parts of the shell, and G the seam or joint between them. As shown, the parts 1-3 are in general of ordinary construction, one of them having a bung-hole D in its head and each having annular ribs or corrugations E, projecting internally or externally, as desired, at suitable points intermediate of its ends. The parts B are shown as cup-shaped half-barrels having the usual bilge or belly as their seamed edges are approached. The seam or joint C is, as usual, formed by folding the flange or edge a of one part over the corresponding flange or edge I) of the other part, and then folding the fold thus made inwardly against the adjacent wall, as in the process known as seaming or doubleseaming. This form of joint as a permanent or normally inseparable connection between the halves or parts of the body is commonly used in such vessels, as is also the form shown in Fig. 3, wherein the flange a of one part B of the barrel is overlapped by the flange b of the other part of the body, the two being sweated, soldered, or otherwise suitably fastened together to make a tight joint.

According to my invention I provide a strengthening or reinforcing hoop within the body or shell of a barrel or vessel composed of permanen tly-connected or inseparable sections or parts, and indentations around the shell engaging with the hoop and holding it in place. This hoop may be variously disposed within the vessel, but I prefer to arrange it as shown in Figs. 1 and 2, wherein the hoop lettered F consists of a single relatively-heavy metallic-ring, and is arranged within the two adjacent parts of the vessel embracing the adjacent portions of each part at the seam or joint between them, whereby the one hoop reinforces both parts at the scam. A similar arrangement is shown in Figs. 3 and l, the hoop lettered F in Fig. 3 being within and embracing both the body parts B, and the hoop lettered F in Fig. at being likewise within and embracing both of the adjacent body parts B". This arrangement is not essential, however, and instead of following this construction two or more internal hoops maybe employed, as shown in Fig. 5, wherein a separate hoop G is employed for each body part, each such hoop being distant from the seam or joint H, between the adjacent body parts or halves I. In this con= struction the hoops G are each held in position within their respective parts by inwardlyprojecting corrugations, ribs, or indentations J, formed in the adjacent metal of the body part, the one nearest the head end being formed prior to the application of the hoop and the other after such application. By thus forming the hoop within the vessel its displacement is prevented, while its reinforcing function is most advantageously availed of, since it resists all compression forces which are applied to the bilge or belly of the barrel, instead of only those applied directly to the hoop, as is the case when it is at the exterior of the barrel, and externally the barrel has all the advantages as to size and shape incidental to hoopless barrels.

Another feature of my invention consists in utilizing the hoop to strengthen the barrel longitudinally as well as diametrically. In carrying out this part of my invention I construct the hoop and barrel with adjacent in.- terengaging faces which abut or interlock and resist either axial separation or compression of the adjacent parts or halves of the body. Preferably this is accomplished in the manner shown in Figs. 1 and 2, wherein the hoop is provided with opposed faces or shoulders c on its outer surface, and the adj acent halves or parts 13 have reciprocal faces cl engaging those of the hoop and preventing separationof the parts or halves or movement of the latter relatively to the hoop, and the hoop is formed with abutting faces 6 and the parts with opposing faces f, engaging to prevent movement of the parts toward each other or movement of the hoop into either part beyond a predetermined extent. The faces 0 are preferably formed by grooving the outer periphery of the hoop, and the correspondin g faces (Z of the parts B by inwardlybent portions or indentation, of these parts. The faces 6 of the hoop preferably consist of the side edges thereof, and the reciprocal faces of the parts B are best formed as indentations, inwardly-projecting corrugations, or ribs in the walls of these parts.

In a barrel or like vessel constructed with the improvements just described the respective parts will be prevented from movement axially toward or from each other by these interengaging faces, and thus the seam between the parts will be relieved from the strain incident to forces tending to such movement. Consequently a proportionate reduction in the liability to impairment of the joint results.

My invention also comprises means whereby the joint or seam between the halves or parts is brought within the face of the bilge or belly of the barrel or vessel. struct the hoop with an annular groove K in its outer face, which groove is opposite the seam C and coincides in depth with the additional thickness due to the seam, and I fold or press the seam into this groove, the seam and groove being proportioned, preferably,

To this end I 0011- so that the former closely fits the latter when pressed home therein. Preferably the faces 0 on the 1100p constitute the side walls of the groove K, and the faces d of the partsB consist of the folds or bends of the joint 0; but this is not necessarily so, as separate or other faces may be provided for performing the functions of these faces. When the groove K is provided for the seam O, and the latter is seated in the groove, the exterior of the vessel has the advantage of having a uniform bilge or belly, while the seam is inclosed by the walls and bottom of the groove to prevent its separation or distortion, and the adjacent walls of the parts or halves are also reinforced by the outer face of the hoop to prevent any distortion near the seam. These various conditions present an advantageous and very complete protection for the joint.

Inconstructing the barrel shown in Figs. 1 and 2, the halves are spun or stamped with their ribs E and face f formed and their opposing flanges a and b outwardly turned, the hoop F is placed within one of the halves until it seats on the face f thereof, the adjacent half is passed over the hoop until its face f engages the corresponding face thereof, and then the seam O is bent and folded according to the usual manner of double-seaming, the folding continuing until the seam is thoroughly seated in the groove K. The barrel is then complete and ready for use.

By my invention the hoop F takes the place and dispenses with the necessity of any internal resistant roller or other provision for preventing collapse of the walls of the barrel during the formation of the double scam, the seam-pressure being entirely taken up by the internal hoop. Thus it is not necessary to provide an aperture at the barrel head through which to insert any tool during the seaming operation. Both heads of the barrel may thus be constructed as solid heads, or one may be solid and the other have the usual bung-hole D.

It will be seen that my invention provides improvements in barrels and like vessels which can be advantageously availed of, and it will be understood that the invention is not limited to the particular details of construction and arrangement set forth as constituting its preferred form, since it may be availed of according to such modifications as circumstances or the judgment of those skilled in the art may dictate without departing from the spirit of the invention.

Fig. 3 shows a modification in which the hoop lettered F is constructed with two grooves L, and the parts 13 with reciprocal ribs or corrugations M entering these grooves, the opposing faces of the grooves and ribs corresponding to the faces 0, (Z, c, and f, described with reference to Figs. 1 and 2. These faces are here lettered o d and ef, respectively. The seam here lies in a groove K.

In the construction shown in Fig. 4 the ribs N are relied on to preserve the hoop F in position, and the joint 0 relied on to prevent separation of the parts.

hat I claim is- 1. In a metal barrel, a body made of two annular sheet metal shells joined together, and a hoop consisting of a single integral piece of metal within said body at the joint between said shells and embracing the inner faces of both, said shells having inwardly indented portions having inwardly projecting faces and said hoop having on its outer wall outwardly extending reciprocal faces, said faces interengaging and preventing axial separation of said shells and hoop.

2. In a metal barrel, a body made of two annular sheet metal shells, a seamed joint between said shells seaming them together, and a hoop consisting of a single integral piece of metal within said body opposite the joint between said shells, said hoop having an external groove embracing said joint, and said joint indented into and entering said groove, said hoop reinforcing said body, and

said interengaging joint and groove holding said hoop in position Within said body, substantially as and for the purpose set forth.

3. In a metal barrel, a body composed of two sectional tubular sheet metal shells, an inwardly projecting and indented double folded seam joint at, composed of, and uniting the adjacent annular edges of said shells, and a hoop consisting of a single integral piece of metal within said body at said joint and embracing the inner faces of both said sections adjacent thereto, said hoop having an external groove receiving the inwardly projecting part of said joint, and said joint indented into said groove whereby said hoop reinforces said body and is preserved in position by said interengaging joint and groove. In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
