METHOD OF MAKING METAL CONTAIN Application filed May 11.
To all whom it may concern:
Be it known that I, CHARLES L. RO\VLAND, a citizen of the United States, residing in Carbondale, "county of Lackawanna, State of Pennsylvania, have invented certain new and useful Improvements in Methods of Making Metal Containers, of which the following is a specification.
This invention .contemplates the production of a container, constructed of metal, comprising a body, usually cylindrical, with closed end heads, the parts orsections of the container being integrally united by welding.
In the accompanying drawings, Figures 1 to 14 show progressively the construction of the container and the contours which may be given it.
Fig. 1 shows a flat plate of rolled metal:
Fig. 2 shows this plate rolled into approximately cylindrical form with its edges overlapped to be welded together as at a:
Fig. 3 shows the complete, welded cylindrical body so produced:
Fig. 4 is a side View of one of the heads 6, partly in section:
Fig. 5, a face view of the same:
Fig. 6, a side View of the other head 0, also partly in section:
Fig. 7, a face view of same: v
Figs. 8 and 9 show the flanged heads 6 and c inserted in the ends'ofthe cylinder.
Where the flanges of the head overlap the side portions of the cylinder, the parts are united by a welding operation produced in stages, that is a section of the joint'is adequately heated and welded and then another section is similarly treated, and so on throughout the whole of the seam. By this method large and perfect containers may be produced, which is not feasible under the method practised in, the of comparatively small containers; which method consists in heating, in a suitable furnace, at one time the whole of the joint and then welding the same by a rolling method. The longitudinal weld in the body of the cylinder above referred to may be effected by a similar stage welding method. A suitable way of accomplishing this is to heat the metal progressively along the line of the weld by trayeling furnaces and then effecting the welding by pressure rolls or impact devices.
Figs. 10 and 11 illustrate crimping the Specification of Letters Patent.

united welded parts of the flanges of the heads and adjacent portions of the ends of the cylinder. In Fig. 10, the inserted head 7) is concave considering the exterior; and its flange and the part of the cylirder to which it is welded are together crimped transversely to the axis of the cylinder or body and, as shown, inwardly toward the center thereof; Fig. 11 shows the same general arrangement, the only difference being that the central part of the cylinder head 0 is flat in a plane at right angles to the axis of the body.
Fig. 12 shows the same general arrangement as Fig. 11 except that the body of the flanged head cis forced outwardly so that in cross-section the body of the head is concavo-convex. Such outward concavo-convex formation of this head,,oand the other head also if originally flat, may be produced by internal pressure. The fluid pressure medium may be admitted through a tapped orifice m in thewall of the body adjacent one of the heads. This may be readily accomplished because the testing pressure may be. carried very materially higher than the pressure of the fluid to be stored or transported in the containerand there is, therefore, no distortion of the head after its initial projection has been effected by the testing pressure. The crimped welded flanged portions of the heads and contiguous endportions of the body not only add strength to the structure but the projecting crimped portion or chime of the structure afi'ords an end depression that serves to prevent shocks thereupon. The containers con-v templated by this invention are preferably attached by a welding operation. The class of containers that I have particularly in mind are for chemicals and are well adapted for the transportation and storage of chlorin.
Of course, the outward swelling of the head 0 when it is in pos'itionand has been welded to produce in its body the concavoconvex shape in cross-section, as already re ferred to, may not be necessary for most purposes.
Now referring to Figs. 13 and 14 the crimpedchime portion, marked in Fig. 13.

body a flanged head,
cl, provides at the end of the container a depression afl'ording protection for the cloally from the central part. of the head to points adjacent the body of the container and that may or may not ,be curved to conform to the concavo-convex head; these pipesg, g are preferably diametrically opposite, as indicated in Fig. 14., Therefore, by placing the container in such position that the pipes g, g occupy a position vertically in line, or substantially so, I may withdraw through the upper pipe g (Fig. 13) any gaseous matter from Within the container first, and may then withdraw through the lower pipe 9 any liquid matter. When the pressure of the contained gas is designed to effect the evacuation of theliquid, the I tap f is first utilized.
When the central portion of the head or heads is expanded or forced outwardly, as described, such special expansion may be performed either before or after the crimping of the weld-united portions 'of the flanges and end parts of the body or cylin-' der, the sequence of these two operations being not of the essence of claims herein. However, I prefer that the crimping or inward turning of the chime-like portions of the vessel should be first completed and afterward the expansion of the heads be eifected by internal pressure.
It has heretofore been the practice of securing the .filling and discharging pipes of contalners of this character to a man-hole plate, which in turn is secured to one of the heads, generally by bolts and made tight" by gaskets.
many cases unsuitable for containers intended to hold chemicals of various kinds. By
Such an arrangement is in the containers by the Weldthe method of this invention are perfectly tight, all parts, ing process, being integra The pipes g, 9 may be attached to the head before the head is welded in the body; or the head to which the pipes are to be attachedis first secured in place, the pipes then attached thereto and the other head body-to complete the container.
Of course, both heads maybe initially flat and be expanded into concavo-convex form by pressure applied to the interior of the container.

5. The method of making a metal container, consisting in first forming a cylindrical body, then inserting within the body flanged heads, the flanges of which extend outwardly and laterally from the body of the heads, integrally 'connecting thebody and heads by welding in stages the adjacent parts of the body and flanges of the heads and in attaching to the inside of one of the heads filling and discharge pipes before both of the heads are Welded to the body.
