SIGNOBS TO VACUUM OIL COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK .RECEPTACLE FOR IETROLEUM AND THE LIKE Application illed October 8, 1928. Serial No. 311,058.

invention is to provide a receptacle, for the purpose in question, with simple and effective means for heating the contents of the receptacle to permit such contents to be withdrawn in liquid form under conditions of 1 temperature in which the contents would readily.

The heating means in question have athe form of a tubular conduit or pipe fixed wlthotherwise be solid or too viscous to flow in the receptacle and adapted for connection with an external source of a Huid heating medium, such as steam or hot water, and the invention'resides in the particular form of such conduit and its relation to the discharge orifice of the receptacle, whereby the desired Aor heads.

result is secured in the simplest manner and with the occupancy of a minimum space by the conduit. The invention com rises also convenient andY effective means or attaching the ends of the conduit to the. walls of the rece tacle in such a way as to avoid leak.- age of t e contents at such points of attachment. i

In the drawings:

Figs. 1 and'2 are, res ctively, V4a plan view and a side elevation o a sheet-metal drum or barrel provided with heating means em bodying the present invention;

Fig. 3 is a sectional view on the line 3-3 in Fig 1 and on a larger scale; and

Figs. 4 and 5 are sectional detail views of the inlet and outlet ends respectively of the heating conduit, together with the means by which` these ends are attached to the walls of the drum. l f

The invention is illustrated as applied to a sheet-metaldrum 1 of ordinary form, having. cylindrical side walls and fiat end 'walls The upper head has the usuallarge filling opening, closed my a cap`2. For the withdrawal of the contents, the drum is provided, in its' side wall, adjacent'the lower ead, with an outlet opening or'spud closed by a plug .3. When the contents of the receptacle are fluid, they may .be withdrawn through this outlet opening with the drum either standing upright, as in Fig. 3, or lying horizontally, with the outlet opening at the bottom. l

The heating conduit in which the invention is particularly embodied comprises a pipe `,bent so as to have two limbs at a right angle with each other. One end of this pipe is connected with `an opening in the upper end ot the drum, while the other end 1s connected with an opening in the side wall near the lower head, -as shown in Fig. 3. One of the limbs of the pipe, therefore, extends vertically from the top nearly'to the bottom of the receptacle, while the other limb extends horizontally across the bottom of the receptacle. Preferably, the heating conduit and the outlet opening are arranged to lie in the same plane;

The form and arrangement of the heating conduit is such as to insure suflicent heating and effective discharge of the contents of' the drum. It will be evident that in withdrawing i the contents it is desirable, at the outset and throughout the operation, to heat and melt the contents at the bottom and adjacent the outlet opening. Thisl result is immediately effected by the horizontal limb of the conduit extending across the bottom. It is necessary, further, that asv the contents at the bottom are withdrawn, the superincumbent contents shall flow and descend, and this result is secured by the vertical limb of theconduit eX- tending'from the bottom to the to of the receptacle.. It should be noted that, 1n either the upright or horizontal position of the receptacle, there is a horizontal limb along the lowermost portion or bottom and avertical limb extending from the bottom to the uppermost portion or top, and that these limbs converge and communicate .at the interior angle adjacent the outlet o ening.

' In order that the eating conduit vor pipe may be conveniently and securely attached to the walls of the drum, the construction shown particularly in Figs.` 4 and 5 is used. 'As shown in Fi 4,this construction includes a bushing 6 aving internal. and external threaded cylindrical surfaces, this bushing having an outwardly extending flange at its outer end and an inwardly extendin ange at its inner end. A nut 9 is screwe on the external threaded surface to clamp the bushing in place in an o ening in the head of the drum, and a gasket g, interposed between the head and the outer ilange of the bushing,

provides a Huid-tight seal at this joint. The upper end of the heater pipe 4 extends into the bushing and is anged at its extremity, and a gasket 8 is interposed between the pipe Harige and the inwardly projecting flange at and a sealing gasket 13 interposed between the bushing and the wall of the drum. In this case, however, a' gland nut 11 is substituted for the plug 5 and arranged to compress n packing 12 around the end of the heating pipe.

The invention claimed is: A

1. Ina receptacle for petroleum and the like, the combination, with a generally cylindrical shell provided with an opening, for the discharge of its contents, adjacent the angle between the side wall and an end wall of the shell, of a tubular conduit, for the passage of externally supplied heating fluid, enclosed within the shell and bent to approximately right-angleform, the limbs of said conduit being substantially parallel, respectively, with `said end wall and side wall.

2. Ina receptacle for petroleum and the like, the combination, with a shell provided with two openings in the walls. thereof, of a tubular conduit, for the passage o f externally supplied heating fluid, extending, within said shell, from one of said openings to the other,

and means, for making a fluid-tight joint between each end of said conduit and the'adjacent wall of the shell, comprising a bushing having internal and external threaded cylin' r11-ical surfaces, an outwardly-extending flan e at its outer end and an inwardly-ex ten ing iiange at its inner end, a nut screwed on said external. threaded :surface and cooperating, `lwithy said v outwardly-extending flan e, to fix the bushinghinythe wall of the shel, an externally threaded and centrally bored member screwed into'the bushing and engaging the end of said conduit, andpacking surrounding the end of the conduit and lcompressed between saidf member and said inwardly extending flange on the bushing.
