Description

Patented Dec. 1, 1953 UNITED STATES PATENT OFFICE Claims.

This invention relates to fluid stirring devices adapted for use upon a cylindrical container, and more particularly to a stirring device for mixing and stirring paint.

It is the object of the present invention to provide a stirring device which may be removably positioned upon the open end of a fluid container, such as a paint can, and which includes a manually rotatable paddle positionable down into the fluid within the container for stirring the same.

It is the further object of this invention to provide a simplified fluid stirring device which is adapted for use upon containers of different diameters.

It is the object of the present invention to provide a paint stirring device which eliminate the use of a stick for such purpose, keeps the users hands clean, and is fully effective as a stirring mechanism.

It is the further object of this invention to provide a simplified and inexpensive paint stirring device which is easy to assemble and which is easy to mount upon the open end of a paint or other fluid container.

These and other objects will be seen from the following specification and claims in conjunction with the appended drawing in which:

Fig. 1 is a plan view of the present stirring device mounted upon a fluid container.

Fig. 2 is a section taken on line 2-2 of Fig. 1.

Fig. 3 is a section on an enlarged scale taken on line 33 of Fig. 2.

Fig. 4 is an elevational view partially in section showing the paddle shaft and handle construction in one piece; and

Fig. 5 is a fragmentary elevational section showing a slightly difierent form of bearing mounting.

It will be understood that the above drawing illustrates merely a preferred embodiment of the invention and that other embodiments are contemplated within the scope of the claims hereafter set out.

Referring to the drawing, a fluid container II, which may contain paint, has bottom wall I2, and is provided at its upper open end with an annular formed flange IS with an inner beading l4.

-Said flange is adapted to removably receive the conventional cover whose depending flange cooperates with flange I3.

I The stirring. device includes a substantially semi-circular formed plate I5 which has a central circularly shaped platform I6 and a pair of horizontally extending annularly shaped flanges- I! and I9.

Platform IS terminates in the upright shoulder I8 which is substantially circular in shape, and the upper end of shoulder I8 terminates in the horizontally arranged flange [1.

Flange I? terminates in the upright peripheral flange 26, which is substantially circular in shape; and the upper end of shoulder 20 terminates in the peripheral horizontally arranged flange I9, which as shown in Fig. 2 extends laterally of the side walls of container I I.

An upright bearing is mounted upon the platform It and consists of the uprights 2! with right angular legs 22 at their lower ends suitably secured to a platform I6, such as by the welds 23. The upper ends of uprights 2| are interconnected by the horizontal portion 2| which has a centrally depressed apertured portion 25 in registry with an upwardly formed apertured portion 24 formed within platform I6.

Thus, the upright bearing 2I2I-22 is secured to the plate I6 and its aperture is in registry with the corresponding aperture formed in plate I5.

Upright manually rotatable shaft 26 is jour nailed through the registering apertures in bearing 2! and platform I6, and extends downwardly into container I I.

The upper end of shaft '26 has a reduced threaded portion 21 upon which the handle 28 is threadably secured at one end.

Horizontally arranged handle 28 has an upright operating element 29 swivelly secured as at 30 to the outer end of handle 28.

The upright, preferably rectangular paddle 3I has a curved upright edge 32 which engages around the lower portion of shaft 26 and is suitably secured therewith as by the welds 33, shown in Fig. 3. The stirring device may be used with the upright paddle 3| alone for certain sizes of containers; however Figs. 2 and 3 show an upright preferably rectangular paddle blade 34 which is hinged at one upright edge to the adjacent upright edge of paddle 3 I.

The hinge employed is so constructed that blade 34 may lie in parallel engaging relation with paddle 3|, as shown in dotted lines in Fig. 2, or may be fully opened into substantial coplanar or parallel relationship with paddle 3 I. 1

The particular hinge employed, generally designated at 35, includes a circularly curved tongue 36 which is formed from paddle 3| and extends loosely through an upright slot 31 formed in paddie blade 34. However, paddle 3| has extensions 39 which are substantially parallel to paddle 3| and which are adapted to limit the opening movement of plate 34 to the position shown in Fig. 3.

Thus, by rotating shaft 26 in a clockwise direction within container blade 34 will open into substantially coplanar relationship shown in Figs. 2 and 3, the outer upright edge of blade 34 being forwardly curved as at 38.

The lower horizontal edges of paddle 3| and blade 34 are serrated as at 40 and are adapted for scraping over the bottom wall l2 of container I. It is apparent that counter-clockwise rotation of shaft 26 would cause a partial pivotal movement of blade 34 and, therefore, would not ing paddle 41 projects upwardly through the aperture in platform I6 and through the corresponding aligned aperture in bearing 2|, and the upper portion of shaft 46 is bent normally of the body of the shaft defining the handle arm 48 which is upturned at its outer end as at 49 to provide a grip for the handle. This provides a more simplified structure wherein the handle is formed as a part of the shaft.

The bearing 2|22 shows one form of journal for shaft 26, however, it is contemplated that other types of hearing may be employed, such as shown for illustration in Fig. 5. In this figure be fully effective for mixing the paint or other The above described stirring device may also be selectively used for a smaller diameter container, such as the quart size container 4|42 shown in dotted lines in Fig. 2. The second container 4| shown in dotted lines is similarly provided with a. conventional internal annular flange 43 and corresponding bead 44 at its open end.

The above described plate I5 is provided with the two spaced upright shoulders l8 and 28 to thereby permit the selective use of the one stirring device with either a large or a small container.

In the preferred embodiment, Fig. 2, the shoulder cooperates with the bead H! on flange l3 and the adjacent horizontal flange IQ of plate l5 bears upon container flange I3. In some situations the shoulder 20 will snugly engage the bead 1, however, as these containers are not standard exactly, there will be situations where the shoulder 20 will be more loosely positioned within and adjacent the bead M.

In the event that the stirring device is to be used for a substantially smaller container, such as the quart container 4|--42, then the upright shoulder I8 is adapted for positioning within and cooperation with bead 44 of the horizontal container flange 43 shown in dotted lines. Of course, it will be noted that the paddle 3| will then be elevated to the dotted line position shown, and the blade 34 will be folded over paddle 3|. Of course, the shaft 26 would be moved upwardly sufficiently so that paddle 3| will bear against the bottom 42 of container 4|.

Horizontally arranged pin or shaft 45 is secured at one end to handle 28 adjacent shaft 26 and provides a means whereby a paint brush may be suspended therefrom and hang down into the container. For this purpose, a small loop of cord is tied around the paint brush handle and a portion of the loop is slipped over the free end of the pin 45.

The present stirring device includes the semicircular plate |5 whereby during the painting operation the same is not removed from the container as the space provided is sufficient for dipping of the paint brush. The straight edge ID of plate l5 provides a brush wiping edge for removing excess paint.

In operation the user holds the plate IS in place with one hand and rotates the handle 28 with his other hand. It iscontemplated that the present mixing device might also be constructed of such dimension as to be selectively used with a pint or quart container. In that case, it is contemplated that the blade 34 may be eliminated, if desired.

Referring to Fig. 4, the upright shaft 46 carry there is shown the central platform 50 corresponding to platform l6 and fragmentarily the adjacent horizontally arranged flange 52 which corresponds to flange I? in Fig. 2. The platform 50 is upturned as at 5| defining a sleeve within which is pressed and secured the cylindrical bearing or bushing 53 which journals manually rotative shaft 54.
