S. E. NORD SELF-DRAINING OIL CAN Filed Sept. 18, 1926 v INVENTOR Ewan E. 4 01" I BY 1% ATTORNEY Patented Get. 16, 1928.

UNITED- STA TES SWAN E. Nomi, 0: SEATTLE, WASHINGTON;

SELE-LDRAINING on. CAN.-

Application filed September 18, 1926. Serial No. 136,326.

My invention has particular reference to improvements in the type of can commonly used by Wholesalers of lubricating oil in making deliveries to the retail trade. practice is, to transport oil for this purpose in cans of asize which permits them to be conveniently handled. The standard can thus used has a capacity of live gallons, and is provided in its body portion with a plurality of circumferential corrugations designed to add rigidity thereto, but which obviously afford oil-retaining recesses interiorly of the can.

In making deliveries from these cans, I have found, owing to the viscosity of the oil, said corrugations, and the time ordinarily allotted for pouring, that approximately three-fourths of a pint ofoil is left in each can afterthe same is deemed to be empty, with the result that the purchaser is deprived of a quantity of oil to which he is entitled,

and apparently without the fault of the seller. As many thousands of these cans are thus emptied daily, the ultimate loss to purchasers is enormous.

The main object of'my inventionis, to practically eliminate this loss, and in furtherance of said object, I provide a can of. this character, rigid in construction yet free of said corrugations, having a bottom portion of a form which allows the residue of the oil to drain quickly into an auxiliary and special I receptacle communicating therewith, and

from whence it can be readily deposited into the container desired. 7

In the accompanying draw1ng- Figure 1 is an elevation of the device complete, its lower portion being partly broken now in operative position for discharging any residue of oil therefrom.

In the preferred embodiment of the invention, the device comprises a cylindrical body portion 1, in which the corrugations referred to have been dispensed with. The top sections of the can 2 and 3, the cover 4, and the handle 5, present the usual construction found in cansof this type; The lower bottom,.designated as 6, is disposed somewhat above the base 7, so as to provide a housing for parts heretofore referred to but which presently will be described with more particularity.

A double bottom 10,: in the formof a hollow, truncated and inverted cone isfastened tothe body of the can,:its smallerend being disposed adjacent. said bottom 6. An auxiliary oil receptacle extends through the bottom 6, is secured to said. end of the bottom 10 and establishes communication for oil therewith Said receptacle is provided with a cylindrical body aortion 11, which terminates at one end in a flared section 12, alfording a strong connecting element between the bottom 10 and the body, of the receptacle, and terminates at the other end in an exteriorly threaded section 13. i V

A cap 14: for the receptacle, adapted to threadedly engage the section 13 and having a leather washer 15 to make is oiltight, is

provided with a circumferential groove 16, I

in which is rotatably mounted a ring 17, having an eye 1S',-carrying a chain 19. A memher, having a flat body portion 20, terminating at one end in a hook 21, is secured to the bottom 6. It serves, through its fastening elements, to support one end of said chain and a keeper 22 for the hook, said keeper being made of spring material. The chain, as is evident, is for the purpose of retaining the cap to the can so it will not be misplaced, and the hook and keeper are designed to carry and retain the cap, through said eye, as shown in Fig. 3," when the cap is removed from the receptacle.

The utilization of the device is quite obvione When the oil has been poured from the can in the usual manner and the can left standing on its base, the elimination of the corrugations mentioned and the oil-retainmg recesses incident to a can having the ordinary horizontal bottom, and the provision,

of a smooth inner surface terminating in the flared bottom,will permit the residue offthe oil to flow toward and be quickly collected in said receptacle and in the bottom 10 adjacent thereto. The can is than placed over a suitable container, the cap removed from the receptacleand hung on the hook,'as shown in Fig. 3,when practically all of theoil remaining in the can will be deposited in the con- I often a number of these cans are emptied at one delivery, and deliveriesof other products are made, thus affording the short time necessary for the residue of the oil to collect and be transferred as just described. If desired, however, immediately after the contents are poured from the can the cap can be removed and the residue of the oil allowed to drip directly into said container.

Under the present construction, the bottom 10, in addition to the function already described, serves to add rigidity to the body of the can, and the fact that the bottom 6 aiiords support for the bottom 10, also increases the stability of the structure. I contemplate that, preferably, this can shall have a capacity for oil the same as the standard cans heretofore mentioned. 7

Vhile I have shown, one embodiment of the invention, 1 may, however, provide other arrangements and constructions for carrying out the same without departing from the spirit or scope of the invention as defined by the appended cla ims,

her, in the form of a hollow, truncated and inverted cone, its smaller end axially aligned with said opening, an auxiliary receptacle for oil extending through said opening and secured to said end of the second-named me1n ber, and an oil-tight cap .threadedly engaged with the free end of the "receptacle.

- 2. A self-draining oil can, comprising a container, a horizontal bottom membertherefor, a double'bottom secured within the contamer, converging downwardly to an outlet,

an auxiliaryv receptacle for oil extending through the member, one end secured to the outlet and adapted to establish communica tion for oil therebetween, itsother end, tree and open, extending below the member, a detachable cap for the free and open end, a sec ond member secured to the first member and exteriorly'thereor", carrying at oneend a hook, provided with a keeper, and a flexible connectionbetween the other end of the second member and the cap.

3. A. self-draining oil can, comprising a container, a horizontal bottom member disposed above the base of the container to provide a housing between the base and the member, a second bottom member, disposed above the first-named member, defining a hollow, inverted cone, an auxiliary receptacle for oil extending through the first member and secured to and adapted to establish communication for oil with the second member, a detachable closure for the free end of the receptacle, and means for suspending the closure within the housing.

4. A self-draining can for viscous liquids, comprising a container, a mouth to the container for dispensing said liquids, a flared bottom member, disposed above the base of the container and converging into and communicating with a drainage receptacle, said receptacle being disposed within the base and adapted to catch the residue of oil remaining in the container after pouring the contents therefrom, and a detachableclosure for the receptacle. 7 c, SWAN E. NORD.
