PAINT MIXING DEVICE.

Application May 18, 1954, Serial No. 430,538
2 Claims. (Cl. 259144) This invention relates to a paint mixing device, and particularly to a paint mixing device in the form of a winged vane adapted to be positioned on the bottom of a paint can so as to cause thorough mixing of the paint when the can is rotated in an oscillatory manner.
It has been customary in the past to mix paints by inserting a stick or other mixing rod into the paint can in contact with the bottom thereof, and moving the stick in a circular motion so as to cause the precipitated pigment on the bottom to become mixed with the liquid in the upper portion of the can, producing a homogeneous mixture. This method has been objectionable due to the fact that the entire bottom surface of the can is not affected by the moving stick, with the result that much of the pigment remains unmixed. In addition, such a mixing technique is laborious and time-consuming.
It is an object of this invention, therefore, to provide a novel paint mixing device which dispenses with the use of the conventional mixing stick.
It is another object of this invention to provide a paint mixing device which insures complete mixing of the settled pigment on the bottom of the can.
It is a further object of this invention to provide a paint mixing device for rapid mixing of paints with a minimum of physical exertion on the part of the user.
A still further object of the invention is to provide a paint mixing device in the form of a winged vane member adapted to freely rest on the paint can bottom and cause a thorough mixing of the paint by oscillatory rotation of the can.
These objects, together with other and additional objects and advantages to be derived from the present invention, will more readily become apparent by reference to the following description and accompanying drawings wherein similar numerals refer to similar parts throughout the several views.
Figure l is a perspective view of the winged vane paint mixing device of the present invention.
Figure 2 is a sectional view of a paint can taken along a vertical plane, and illustrating how the mixing device.
of Fig. 1 is inserted thereinto.
Figure 3 is a sectional view of a paint can taken along a vertical plane showing the paint mixing device in position for use on the bottom of the can, and illustrating by arrows the oscillatory motion of the can to achieve mixing of the paint therewithin.
Referring to the drawings, and particularly to Fig. 1 thereof, it will be seen that the paint mixing device of the present invention is of a one piece construction being preferably made from hard rolled steel sheet approximate- 1y ,5 inch in thickness. As shown therein, the said device is cut or stamped from a substantially rectangular sheet of metal so as to consist of a main body portion 10, and a pair of triangular winged portions 11 and 12. The said triangular winged portions are formed by cutting the metal sheet upwardly and toward the center thereof from a point 13 on the bottom edge of the sheet slightly inboard from the side edges 14 thereof, to a 2,774,580 Patented Dec. 18, 1956 ice 2 point 15 below the top edge 16, as shown. The thus cut triangular portions are bent outwardly and in opposite directions from the plane of the main body portion 10 so as to lie at right angles thereto. It will be noted that the thus bent triangular portions are separated by a segmental wall 17, which is actually part of the main body portion, so that the said triangular portions are ofi-set, as depicted in Fig. 1.
For the purpose of facilitating the insertion of the mixing device into the paintcan, one of the upper corners of the main body portion 10 is cut off obliquely as indicated at 18. This'feature is of vital importance to the overall efficiency of the device, inasmuch as itpermits of the insertion of a larger mixing device into the can than would be possible without the corner being cut off; and thus with a larger and heavier device a more thorough and more rapid mixing is achieved. The mode of insertion of the device which takes advantage of the obliquely cut corner is depicted in Fig. 2.
In using the above-described paint mixing device, the lid or cover of the paint can is removed and the device is grasped on the section of the main body portion 10 remote from the obliquely cut corner 18. Then while inserting the device into the can, the said device is tilted slightly as shown in Fig. 2 so that as the cut corner 18 passes through the can opening, it lies in an approximately perpendicular plane relative to the bottom of the can. This motion permits the device to clear the rim of the can surrounding the opening. Once the device has cleared the rim of the can, it may be released, whereby it will settle to the bottom of the can by virtue of its own weight, assuming an upright position, as shown in Fig. 3. In this position, the bottom edges 19 and 20 of the triangular winged portions 11 and 12, together with the remaining bottom edges of the main body portion 10, dig into the thick sediment on the bottom of the can until they come to rest on the can bottom proper. This is an important feature of the present invention, for upon replacing the lid of the can and grasping the bail thereof and oscillating the can by twisting the wrist, as shown in Fig. 3, the bottom edges 19 and 20 of the triangular portions 11 and 12 scrape the bottom of the can so as to loosen the sediment therefrom. At the same time the side edges 14 of the main body portion 10 scrape the sediment loose from the lower portion of the wall of the can. This is achieved by a movement of the mixing device relative to the can caused by a change in the direction of rotation of the can with a resultant intermittent change in momentum of the mixing device.
Once the sediment has been loosened as just described, the turbulence produced by the liquid contents of the can flowing about the protruding portions of the mixing device will cause the said sediment to be quickly dissolved.
It is to be particularly noted that the scraping action of the triangular portions 11 and 12 insures a complete and rapid mixing of the paint, as almost the entire bottom surface of the paint can is subjected to a scraping action. In addition, the simplicity of the mixing device structure provides no crevices or apertures of any type which might be prone to the collection of undissolved sediment, further contributing to the assurance of complete mixing.
A paint mixing device of the type contemplated by the present invention may be installed in the can at the factory so as to be included in the sale of each can of paint, or it may be marketed separately and inserted into the can as described above.
It is thus seen from the above discussion that a novel paint mixing device is presented by this invention which is extremely simple in construction, and which insures a degree of mixing heretofore unattained. And this degree of mixing can be attained by a mere twist of the wrist in only five minutes.
Although the present discussion of this invention has been limited to the above-described preferred embodiment, variations thereof are possible without departing from the spirit of the invention. It is not intended, therefore, that the invention be limited to the particular embodiment disclosed, but rather only to the inventive concept as defined by the appended claims.
