Patented July 17, i951 AERATOR FOR MINNOW BUCKETS Emil Volenec and Fred Charles Kohagen, Minne- Kohagen assignor to said apolis, Minn.; said Volenec Application June 21, 1946, Serial No. 678,469

The present invention relates to aerating apparatus for water containers and is more particularly concerned with a device to be attached to minnow buckets.

The primary object'of the invention is to provide a device to supply oxygen to a water container without the use of electrical or mechanical pumps.

Another object of the invention is to provide a device of the character referred to which can be readily attached to a container.

A further object of the invention is to provide a device of the character to which can be operated by an ordinary bulbous bellows to oxygenate the water in a minnow bucket.

Still another object of the invention is to provide a simple and inexpensive oxygenating apparatus for attachment to water containers.

With the foregoing and other objects and advantages in view the invention consists of the novel construction, arrangement and combination of parts hereinafter described and claimed.

In the accompanying drawings illustrating the invention,

Figure 1 is a top plan view of a minnow bucket constructed in accordance with the invention, the top being broken away partially to expose interior construction.

Figure 2 is a vertical transverse section thereof on line 22 of Figure 1, and

Figure 3 is an enlarged fragmentary horizontal section on line 33 of Figure 2.

Like numerals, as used in the description and drawings, designate the same structural parts.

ID is a rectangular, box-like metal water container with an interiorly projecting bead I I on its rim to serve as a stop for the hereinafter described screen unit, and a hinged lid or cover l2 designed to be fastened down by means of a pivoted latch l3 which engages a keeper I l projecting from said rim and through the top. In proximity to the said fastener the top is provided with a plurality of round holes to drain off water, as desired, without removing the top.

Mounted perpendicularly on a base plate It, secured centrally on the bottom I! of the bucket, is a post consisting of a round rod l8 which extends short of the bucket lid and serves as a guide for a tubular sleeve l9.

Fastened to the bottom of said sleeve by means of upper and lower dies 20, is a concave, wire screen 2|, with an annular rim plate 22 fastened to its circular edge. The disks overlie and under lie axial bottom portions of the screen and are secured to sleeve I9 in any suitable manner.

4 Claims. (01. 43-57) Thus, the sleeve and screen are connected together for unitary vertical movement.

Projecting diametrically from said rim plate are two angular brackets 23 only one of which is shown. Such brackets 23 are formed with small screw holes in the free ends. The wire screen is of suitable diameter to pass down through'a circular opening in an horizontally disposed plate 24, rectangular in form and suitably dimensioned to freely fit the interior of the bucket. The two brackets 23 on the screen rest against plate 24 and are secured thereto by screws 25, to unify the plate and screen. The slidable sleeve [9 'is provided on top with a cross bar 25, serving as a handle to lift the unit. As aforesaid, the bead is engageable with the marginal edges of the plate 24 to limit upward movement of the unit. The screen and plate comprise means for elevating the minnows in the bucket to a point adjacent the upper edge thereof whereby a minnow may be selected for the purpose of bait in a well-known manner.

An angular air tube 21, of copper or other suitable non-corrosive material, is provided with an open end on its vertical portion and a communicating tubular ring 28, with perforations, on the extremity of the other portion, which is designed to lie on the bottom of the bucket. The tubular ring is passed over the post [8 and surrounds the base thereof. Plate 24 is provided with a plurality of apertures 29 for the escape of oxygen to the water above.

'When the bend in pipe 21 is a sufiicient distance from the center of the bucket, the vertical portion of the pipe is located in a corner with the open end in proximity to the top, as illustrated, and is thereby braced. To permit the passage of the pipe 2'! therethrough and facilitate the movement of the plate 24 into and out of the container i0, its corner adjacent the pipe 21, is cut away as at 24. To permit free bending of the hereinafter described hose coupling bead l l is also cut out at said corner.

A bulbous bellows 3!] is attached to the lid of the bucket, centrally, by means or a tubular plug 3| to seal the connection. This plug is exteriorly threaded on the outer end and projects below the under surface of the lid to receive an elbow pipe 32. A short length of hose coupling 33, provided interiorly with an helical spring 34, connects the end of pipe 27 to the end of the said elbow. The passage-Way through said plug provides the air outlet for the bellows and an air intake -35 is provided on the opposite end. A suitable intake valve, such as a ball-valve, is provided for the intake to contain the air which is sucked in when the bellows is inflated in forcing air into pipe 21 and through the air escape holes in ring 28 to oxygenate the water in the bucket. A number of compressions of the bellows, will accomplish this result, and the operation may be repeated when deemed necessary.

The bucket is provided with asuitably shaped bail 36 with a hand grasp 31, and a flange 38 depends from the front of the bucket lid and overlaps the side of the bucket, thus serving to reinforce the closure.

As different embodiments may be made of this inventive concept and modifications may be made in the embodiment hereinbefore shown and described, it will be understood that the matter herein is to be interpreted as illustrative merely, and not in a limiting sense.
