Description
Nov. 3, 1953 G. w. LUDOWITZ CONTAINER BOTTOM STRUCTURE Filed May 27, 1950 62-0965 ((1 lwow/rz,
Patented Nov. 3, 1953 UNITED STATES PATEN OFFICE CONTAINER BOTTOM STRUCTURE George Ludowitz, Los Angeles, Calif. Application May 27, 1950, Serial No. 164,790
2 Claims.
This invention relates to containers, and particularly to a barrel type of container adapted to be evacuated by pumping the contents out through a pipe extending from the top to the bottom of the barrel.
Many articles of commerce are packed and shipped in barrels of various types, one such article being lubricants of varying viscosities, which are shipped in steel barrels. Such a lubricant may be the type used for greasing automobiles in garages and at filling stations, the grease being removed from the barrel by the insertion of a pipe at the axis of the barrel and terminating adjacent the bottom of the barrel. The majority of these barrels are of cylindrical shape with one or more reinforcing ribs encircling each barrel. It has been found that, since the lubricant is a heavy grease having a viscosity which does not let the grease fiow readily, it is pumped from the center of the barrel, leaving a certain amount in the corner of the bottom of the barrel in the form of a triangular section. This grease is actually wasted, since it cannot be pumped to the grease guns and it must be removed before the barrel can be refilled. This cleaning of the barrels also consumes considerable time.
The present invention permits substantially the complete emptying of the barrel, so as not to waste any lubricant, and thus, aids in the cleaning of the barrel for refilling. It may be applied to cylindrical barrels now in existence, or it may be incorporated in new barrels.
The principal object of the invention, therefore, is to facilitate the removal of a heavy lubricant from a barrel through a single pipe.
Another object of the invention is to provide an adjunct to a cylindrical barrel which permits removal of heavy grease therefrom at a single point.
A further object of the invention is to provide an improved joint between a closed funnel insert in a grease barrel to permit the removal of all the grease from the barrel.
Although the novel features which are believed to be characteristic of this invention will be pointed out with particularity in the appended claims, the manner of its organization and the mode of its operation will be better understood by referring to the following description, read in conjunction with the accompanying drawings, forming a part hereof, in which:
Fig. 1 is an elevational view, partly in crosssection, of a barrel embodying the invention.
Fig. 2 is a detailed view of the joint used in the barrel of Fig. 1.
Fig. 3 is a detailed view of the joint used in a straight sided barrel, and
Fig. 4 is a perspective view of the adjunct inserted in the barrel.
Referring now to the drawings, a cylindrical barrel 5 has two outwardly extending reinforcing ribs 6 and land a bottom member 9. Mounted on the top cover In of the barrel is a pump II which will pump the grease from the barrel through a, pipe 12 having its intake end near the bottom of the barrel.
The barrel 5 is a normal barrel, in which has been inserted a closed funnel-shaped adjunct l5. This funnel has side walls which taper approximately forty-five degrees to the horizontal, and a rubber gasket I6 around the upper cylindrical rim portion ll thereof. This gasket may be of rubber or similar material, and tapered, so that its larger dimension is on the inside of the rim ll, as shown at 20, and its smaller dimension at the other side, as shown at 2|. The gasket is tensioned outwardly when attached along the forty-five degree Wall of the funnel.
Thus, before the barrel 5 is filled, the funnel adjunct i5 is inserted so that when it reaches the rib l, the gasket 16 will conform to the internal surface of the rib I, a portion being wedged between the straight side wall of the barrel and the rim I1. That is, the gasket will not only conform to the configuration of the barrel rib I, but will form a substantially continuous surface between the straight wall of the barrel and the forty-five degree wall of the insert l5, so that the flow of grease along the wall of the barrel will not be impeded. The joint so formed between the rim I1 and the barrel 5, as shown in Fig. 2, is also grease-tight, so that no grease can get under the forty-five degree wall of the insert.
If the barrel does not have any reinforcing ribs, or the ribs are not in proper position to accommodate the funnel l5, then the gasket [6 will be wedged parallel with the side wall of the barrel, as shown at 23 in Fig. 3. After the funnel has been inserted, the barrel may be filled with grease. When the grease is to be removed, the pipe I2 is inserted, and, as the level of the grease falls below the rim I1, it will slide down to the central portion of the funnel I5, so as to be pumped out from the barrel. The only grease remaining will be a very thin layer immediately under the end of the pipe l2.
When the invention is applied to original barrels, the bottom member 9 can be eliminated and the funnel l5 welded to the side walls of the barrels.
I claim:
1. A combination to permit the material in a barrel to concentrate in a small area at the bottom of the barrel Where it may be removed therefrom comprising a cylindrical barrel, a. frustoconical element having a cylindrical rim terminating in a free edge at the large diameter end thereof and a wall with a slope such that the material in said barrel will slide down said wall by aemgsze gravity, said element being positioned at the bottom of said barrel with the large diameter and uppermost and having a small substantially flat area at the bottom thereof, and a flexible gasket attached to a portion of said element on the outside surface thereof only at points downwardly spaced from said free edge and extending over said free edge so said gasket can adjust itself to different contours of the internal surface of said barrel when positioned therein.
2. A combination in accordance with claim 1, in which said gasket has an unattached loop over the free edge of said rim of said element, the free edge of said gasket being positioned along the inner surface of said cylindrical rim and terminating short of the beginning of the sloping wall of said element.
