To all whom z't may concern: l
Be it known thatI, ERNEST E. BELL, acitizen of the" United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new; and
puseful Improvement in Sheet-Metal Bartype which can be easily handled and another object of the invention is to rovide a barrel which can be quickly an easily manufactured and will when completed, be leakproof and capable of containing volatile and non-volatile liquids.
Another object .of the invention is to provide a bilge barrel of such construction that ,the greatest strength will beplaced at the points where the strain is greatest.
Another object is to provide a barrel composed of a plurality of parts so united as to eliminate the formation of ridges or shoulders upon the interior.
`With these various objects in view the invention consists in the novel features of construction hereinafter fully describedand l set forth in detail in the appended claims.
prises a head and the sides, these sides being curved or flared outwardly as shown on the lpro er arc according to the size and shape of the arrel. The centralcor intermediate portion is in the form of a wide band but this also is given a curvewhich corresponds to the curve of the sides of the end portions, producing when the parts are united a continuation of the said sides so that thebarrel as a whole will have the or 'bilgc-i.'
yproper curvature Ihe end portions A are preferably made of thm sheet metal and the intermediate portion B is made of somewhat thicker metal.
lIn practice it is preferred tohave the central or intermediate portion about double the thickness of the metal ofthe endl portions. The edges of the end, portions are intended "to telescope over the edges of the central or intermediate portion and these intermediate portions are cutaway or rabbeted as shown at C, this cut-away portion or rabbet being substantially of the same depth as the thickness of the end portion edge. Thus, when the parts are telescoped, the edge of the end portion snugly its over the reduced edge of the central or intermediateportion and provides upon the exterior, a substantially unbroken surface. The joint is made smooth upon the interior to prevent the lodging of sediment within. the barrel at these points. If desired a weld can be made at the point D in order to prevent leakage.
The joint betweenv the parts A- andv B is made as close and accurate as it is possible to docommercially, and in order to protect these joints, I provide sheet metal hoops E which encircle the barrel at the points where the end portions and intermediate portions meet. In practice this hoop is heated before being placed upon the barrel and is properly positioned before it cools and by thismeans a perfectly rigid joint between the sections is obtained. j
It will be noted that the hoop E is curved slightly in cross-section and the innermost end thereof is adapted to fit into a slight annular depression or groove F produced in Y theexterior face of the intermediate portion and the outer end is also adapted to similarly engage 'an annular groove or depression G formed in the sides of the end portions, these depressions being provided to enable the hoop E`to envelop the joint of the sections as closely as possib e.
Furthermore these annular depressions or corrugations tend to strengthen the vend and intermediate portions at the points adjacent thereto and also enable the-said portions to be brought into approximate accurate shapes for intcrtting or telescoping.
As a matter of additional recaution welds can be made at the points and I where the ends of the hoop contact respectively with thle intermediate and end portion of the barre A sheet metal barrel constructed as herein shown and described will be inexpensive and can be quickly and easily manufactured and assembled. It is `only necessary to shape" up the end portions, roll the central band or portion into proper cross-sectional shape and then fit the opposite end portions on to the same from opposite sides. The hoops are then heated, forced into place, and the barrel as a whole completed.
Aspreviously stated, welds can vbe made at the points where the end portions and intermediate portion unite and alsoiwherethe hoops contact with the central and end portions. A
The central or intermediate portion being thicker than the end portions, is able to stand.1 the additional strains placed`thereon and the annular corrugations impart considerable rigidity to the device as a whole, and the metal hoops shrunk thereon add materially`to the strength and rigidity of the sheet metal container.
In Fig. 3 I have shown a slight modification in which the edges of the end portions are ,bent outwardly back upon themselves as indicated at K and this reenforced. or beaded edge is brought into engagement with the rabbeted edge L ofthe intermediate or central portion and the hoop M is formed with an inwardly projecting portion N adapted to fit in the groove O While the other end of this rin or hoopis curved as shown at P to fit un ver the reenforced or beadededge of the end portion. If desireda weld can be madeA at the point D and also atrthe points H and I in order to secure an absolutely tight barrel.
Upon the exterior of each end portion there is fitted a chime R, this chime being formed' of metal and rigidly connected to the exterior of end portion to provide a suitable means for heading or lifting the barrel. The details of the ychime and the manner of connecting the same form the subject matter of a se arate application iled at even date herewit and consequently detailed explanation of this chime 1s unnecessary herein. In Fig. 4 I have shown a Still further modiiication in which the end portions A are made considerably deeper or longer than those shown in Flgs. 1, 2, and 3 and the intermediate portion B considerably shorter but the opposite edges of the intermediate portion are reduced and the edges of the end portions are brought into .telescopic engagement therewith and then welds can be made at the jolnts between theend portions and intermediate portion if desired. A single hoop C is employed, th1s hoop encircling the barrel at the juncture of the end with the intermediate portion and 1. A sheet metal barrel comprising afi in termediate portion and end portions, the walls of said parts being curved to provide a bilged barrel, the edges of the end portions being `telescoped over the edges of the intermediate portion, the/edges of said intermediate portion being reduced to receive theredges of said end portions, said interf Y mediate portion having annular depressions spaced from said reduced edge portions and bands encircling the joints between the Aintermediate and end portions, one edge of each band engaging the adjacent annular depression in the intermediate portion, the other edges of said bands being held in locked relation with the adjacent edges oi the end portions.
. 2. A sheet metal barrelF comprisingvend portionsv and an intermediate ortion curved to provide a bilged barrel w en assembled the-edges of thev end portions telescoping upon the edges of the intermediate portion,
said end portions and intermediate portions l being formed with exterior annular grooves `or depressions upon opposite sides of the joint between the end portion and intermediate portion and a hoop encircling said barrel and enveloping thev joint between the end and intermediate portions, the edges of said i' hoop being in engagement with the annular depressions in the intermediate and end portions.
3. A sheet metal barrel comprising an intermediate portion and end portions the walls of said parts being curved to provide a bilged barrel, the edges of the end portions being 'telescoped over the edges of the inter-r r mediate portion, said intermediate and end portions havingfexterior annular grooves adjacent their meeting ed es, a weld at the exterior joint of said en and intermediate portions and a hoop fixed upon said bar rel the edges of said hoop engaging the exterior Yannular grooves adjacent the edges of the intermediate and end section.
In testimony whereof, I hereunto aix my signature.
