PAINT STIRRING AND MIXING DEVICE Original Filed April 13, 1928 219. i Q i ZIg E l7 INVEN'i'ORS WITNESSES j'rederick-Sahzayeier lg Fabian/Mia? u 20 BY W, ATTORNEY Patented Feb. 11, 1930 UNITED STATES PATENT OFFICE FREDERICK SCHLAGETER AND IABIAN MALETSKY, OF PATERSON, NEW JERSEY PAINT STIRRING AND MIXING DEVICE Application filed April 13, 1928, Serial No 269,735. Renewed December 17, 1929.

This invention relates to a stirring and mixing device which is particularly designed as a means adapted to be attached to a paint can or container for stirring the same to mix the solid or heavier ingredients with the liquid or lighter ingredients.

Practically all varieties of paints, lacquers or other similar coating substances contain a heavy or solid ingredient which is suspended in the liquid or lighter ingredient when they are properly mixed together for use. Invariably the heavier or solid ingredient settles in the bottom of the container and forms a viscous mass if permitted to stand for any appreciable length of time, which sediment or mass is difiicult to stir for remixing with the liquid ingredient. The usual practice is to employ a stick or other similar makeshift stirring implement of this nature, which in addition to being tiresome and difficult consumes considerable time and entails untold labor.

The present invention comprehends an im proved means designed as an attachment for a paint container which greatly facilitates and expedites the stirring and remixing of the liquid and solid ingredients, in addition to functioning as a means for thoroughly mixing various color pigments.

The invention more specifically comprehends a stirring and mixing device including a rotary blade and manipulating crank and means for supporting and mounting the same on a container whereby the blade is permitted axial downward movement from an initial position resting on the upper surface of the solid mass to a final position in contact with the bottom of the container, said blade gradually moving down on the upper level of the mass as the same is dissolved and suspended in the liquid ingredient.

Other objects reside in the simplicity of construction and mode of use of the device, the facility with which it may be attached to the paint receptacle or removed therefrom, the economy with which it may be produced and the general efficiency derived therefrom.

With the above recited and other objects in view, reference is had to the following description and accompanying drawings, in

which there is exhibited one example or embodiment'of the invention, while the claim defines theactual scope of the same.

1 In the drawings:

Figure 1 is a vertical sectional view through a paint container illustrating the stirring device associated therewith, parts of the device being shown in section to disclose the underlying structure. 1

Figure 2 is a horizontal sectional view taken approximately on the line indicated at 2-2 in Figure 1.

Figure 3 is a fragmentary sectional view illustrating the device supported on a different type of container.

Referring to the drawings by characters of reference, 10 designates a shaft which is provided with a plurality of radially disposed blades 11, preferably constructed from lengths of heavy wire or rods bent upon themselves to form superposed arms 12 extending through the shaft 10 and connected by a bight 13. In practice, the bight portions 13 of the several blades will be spaced at different relative distances from the shaft 10 so that they will move in different paths and contact with different portions of the contents. The bight portion which is spaced farthest away from the shaft has an outwardly offset portion 14: which will engage with the inner wall of the container and effect the dislodgment of the ingredients therefrom. r

The means for attaching and supporting the shaft, and blades for rotation within the container, consists of a pair of inverted substantially U-shaped frame elements 15 including a bight portion 16 and a pair of depending arms 17 the bight portion 16 being arranged in crossed relation and having aligned central apertures 18 serving as a bearing within which the shaft is loosely journaled for axial movement. The lower ends of the arms 17 are attached to an annulus or ring 19 which is of such a diameter as to closely fit within the upper open end of a receptacle A. From their points of connection with the annulus, thearms 17 are offset outwardly to provide terminals 20 spaced from the outer periphery of the annulus and engaging over the outer side of the upper end of the container A. A crank arm 21 having a handle 22 is connected with the upper end of the shaft and constitutes means for manipulating the device.

In use and operation, after the supporting frame is fitted to the upper end of the container, the blades 11 will sinkinto the liquid contents B until they contact with the solid 10 or heavier ingredients C at the bottom of the receptacle. By turning the crank hane dle 22 and exerting a slight downward pressure thereon, the blades will gradually erode the solid or heavier ingredients and mix and 15 suspend the same in the liquid or lighter ingredients B, the blades and shaft gradually moving downwardly astlie level of the solid ingredients recedes. In view of the fact that some containers are provided with an inwardly projecting flange D having an annular groove or depression E, the terminals 20 of the arms 17 are extended below the lower end of the annulus or ring 19 whereby the deviceimay be supported on this form of container, as illustrated in Figure 3 of the drawings.

From the foregoing, it will thus be seen that a simple, effective and highly efficient stirring and mixing apparatus has been devised by virtue of which coating materials such as paints or lacquers may be readily stirred and mixed for use.

hat is claimed is:

A paint stirring and mixing attachment for paint receptacles, including a shaft having a crank handle for manipulating the same, radially disposed blades carried by the shaft and a frame for attachment to the receptacle, said frame including a pair of crossed substantially inverted U-shaped members, the intersecting bight' portions of which are provided with aligned openings constituting a bearing for the, shaft, and an annulus connecting the lower ends of the depending legs of the members, the free terminals of the legs being outwardly offset to present inconjunction with the annulus embracing means for the upper edge of the receptacle.
