METAL 'RECEPTACLE.

SPECIFICATION forming part of Letters Patent No. 650,949, dated June 5, 1900.

Application filed August 9, 1899. serial No. 726,678. (No model.) I

To all whom it may concern:

Beit known that 1, JOHN E. PHILLIPS, a citizen of the United States, residing at J oliet, in the county of Will, State of Illinois, have invented certain new and useful Improvements in Metal Receptacles, of which the following is a specification.-

' Referring to the accompanying drawings, wherein like reference=letters indicate the same or corresponding parts, Figure 1 illustrates one form of my improved device, partly shown in vertical section. Fig. 2'is a plan View of a portion of the parts shown in Fig. 1. Fig. 3 is a sectional view of a modified form of my invention, hereinafter to be more fully described.

The object of my invention is to remedy the defects existing in metal receptacles used for the purpose of transporting commodities usually shipped in barrels or casks; and to that end it consists in providing a receptacle formed of stamped or pressed sheet metal and having the general symmetrical outlines of a cask or barrel.

In the accompanying drawings, A is a receptacle of my invention, the same being formed of two parts a a, the part a being telescoped into the part a and attached thereto by means of welding or by any other suit' able means. Both the parts a and a are made with peripheral step-shaped corrugations or ledges a which ledges act to gather the excess metal created by forming into semibarrel-shaped parts flat pieces of metal and, further and more particularly, act in the place of the hoops customarily employed to strengthen wooden or sheet-metal barrels,

' said strengthening function being one of the essential features of my invention.

I am aware that barrels and casks have heretofore been formed of sheet metal, said vessels being provided with inwardly or outwardly extending S-shaped or U-shaped corrugations. My invention differs essentially and radically from the said prior constructions in that the corrugations formed in the periphery of my barrel or cask are stepshapedthat is to say, the corrugations consist of longitudinally-extending walls or portions and transversely or approximately transversely extending walls uniting the adjacent ends of the said longitudinally-extending walls. This construction has many advantages over the prior U or S shaped corrugations. One of these advantages is that it enables me to form the two parts of my cask orbarrel from a flat sheet of metal by means of a male and a female die, which is not possible with either a U or an S shaped corrugation;

secondly, these step r shaped corrugations form transversely or approximately transversely extending walls, which produces a series of flanges or walls which receive the lateral strain upon the periphery of the barrel edgewise, which is not true of a U or an S shaped corrugation, and, thirdly, these stepshaped corrugations produce a barrel which is readily washed by flushing the inside thereof, in that there are no double-walled grooves or recesses to catch and hold sediment and dirt, such as is constituted by either a U or an S shaped corrugation.

Where the transversely or approximately transversely arranged walls of the stepshaped corrugations are short, as here shown, it will be readily understood that, they do not extend exactly at right angles to the cask or barrel; but it will be readily seen that owing to the fact that these walls are short they present approximately transversely arranged However, the length of these transversely or approximately transversely arranged walls -of the step-shaped corrugations can be varied without departingfrom the scope of my invention, as will be readily understood by those skilled in the art. Attention is also directed to the fact that the longitudinallyarranged walls of the step-shaped corrugations are here shown many times longer than the transversely-arranged walls thereof, and this construction is the preferred form, for it enables me to more conveniently and to more readily form the two parts of the-barrel by a ICO stamping operation from a sheet of flat metal, though this may also be varied without departing from fthe scope and spirit of my invention, as will be readily understood.

As illustrated in Fig. 1, the telescoping or overlappinginner ends of the two parts a and ct of the barrel are preferably bulged outward between their extremities after they are telescoped, whereby a tight joint is more readily and perfectly accomplished by being afterward welded or otherwise united.

lly utilizing the receptacle of my invention a symmetrical vessel of comparatively-light weight is obtained which may be subjected without danger of leakage to great pressure, and therefore may be used even for the purpose of shipment of gases.

It is obvious that the ledges may be as many and as far apart as desired; that either part (L or a may telescope the other part; that the heads may be either concave or convex, and that a bung-hole B may be formed in either one or both of the ends, or in the side of the receptacle, at any suitable point, and it is further obvious thatin place of a bunghole a solid fixed head or bottom or, in addition thereto, a removable head or cap 0, as illustrated in Fig. 3, may be employed, and it is further obvious that instead of telescoping one of the two parts a a into the other their edges may be welded together or brought together and there confined by means of aband orother similar and suitable means without departing from the principle of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. A sheet-metal cask or barrel composed of two separate truncated cone-shaped portions, the two truncated cone-shaped portions provided with oppositely projecting stepshaped corrugations, substantially as shown and described.

2. A sheet-metal cask or barrel consisting of two truncated cone-shaped portions, each portion having peripheral step-shaped corrugations, the longitudinally-extending walls of the inner step-shaped corrugations of each portion being relatively longer than the longitudinal walls of the other step-shaped corrugations, and the said longer and inner walls overlapping each other and united together, substantially as described.

3. As an improved article of manufacture a sheet-metal barrel or cask consisting of two truncated cone shaped portions united at their diverging ends, each portion provided between its ends and their united point with peripheral step -shaped corrugations, substantially as described.
