BY WM 3M1):

United States atent the 2,712,396 i atented July 5, 1955 PRGPORTIQNAL MIXENG CQNTAINER Banana C. Mowat, Elkhart, Ind.

Application November 26, 1951, Serial No. 258,179 1 illairn. or. 220 ss This invention relates to new and useful improvements and structural refinements in containers, particularly cor: tainers such as are employed for storing and dispensing fuel for two-cycle internal combustion engines.

Engines of that nature, such as outboard motors used on boats, utilize fuel consisting of a mixture of gasoline and oil which are mixed in a predetermined proportion, and difficulty is commonly experienced in maintaining the mixture at proper proportion during refilling after the container has been partly emptied.

The principal object of the instant invention is to facilitate expeditious and accurate mixing of the constituents in proper proportion, this being facilitated regardless of Whether the container is totally or partially empty.

Another feature of the invention resides in the provision of means for varying, in a selective, predetermined manner, the proportions of the mixture when so desired.

Some of the advantages of the invention reside in its simplicity of construction, in its efiicient and accurate operation, and in its adaptability to economical manufacture.

With the above more important objects and features in view and such other objects and features as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

Figure 1 is a vertical sectional view of an embodiment of the invention;

Figure 2 is a vertical sectional view of the gauging tube, and

Figure 3 is a fragmentary elevational view, partially broken away, showing the gauging tube in an inverted position.

Like characters of reference are employed to designate like parts in the specification and throughout the several views.

The mixing container herein is designated generally by the reference character 50 and comprises a receptacle 52 having a filler plug 54 in the top wall 56 thereof, the latter also being equipped with a screw threaded neck 58 to accommodate a screw threaded portion 60 of a removable closure plug 62. The upper end portion of a transparent gauging tube 64 is suitably mounted in the plug 62, the tube being open at the lower end 66 thereof and the outer surface of the tube being provided with longitudinally extending strips 68 of liquid-sensitive characteristics, such as for example could be achieved by grinding if the tube were made of glass.

The capacity of the tube 64 is in predetermined proportion to the capacity of the receptacle 52 and when in this embodiment of the invention the container is partly emptied of its mixture, the tube 64 may be withdrawn by removing the plug 62 from the neck 58, while at the same time observing the level which was marked on the sensitive strips 68 of the tube 64 by the liquid in the container.

The tube 6% may then be inverted into the position shown in Figure 3 and filled with oil to the level marked thereon by the liquid as aforesaid, after which the oil may be emptied into the receptacle 52 and the remainder of the receptacle filled with gasoline to again assure the maintenance of proper proportions of the mixture.

it is believed that the advantages and use of the invention will be readily understood from the foregoing disclosure and accordingly, further description thereof at this point is deemed unnecessary.

While it; the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described the invention, what is claimed as new is:

A mixing container comprising a receptacle having a predetermined capacity and including a top provided with an opening, a removable closure plug for said opening, a gauging tube secured at its upper end to said plug and disposed in said receptacle, the capacity of said tube being in predetermined proportion to the capacity of the receptacle, the plug closing the upper end of said tube, the lower end of the tube communicating with the interior of the receptacle, said tube having at least one liquid sensitive strip thereon extending the full length thereof, said tube being open at the bottom thereof for gauging liquid level thereon.
