Patented Oct. 15, 1918* fizz/6712 57" loo/5 JZw/za/Qu/d 'ii'ours JILUNDAHL, oF cHIcAeo, ILLINOIS.


if To all whom it may concern:

Be it known that I, Louisa-J. Luivparrn, a

citizen of the United States, and a resident of Chicago, inthe county of Cook and State of Illinois, have invented certain new and useful. i n iq m s s n P ntrM X ng T "9 ich he ell winsgi a pep afieet My invention relates to an improved tool pattisl lerly adapta l fo breaking p and mixing paint in receptacles such as cans.

. .l/Vhere paint is sealed in-receptaclesand allowed to stand a while the paint body soon settles at the bottom of the receptacle and hardens while the oil or solvent accumulates at the top of the receptacle. It is very difiicult to break up the settled paint and to thoroughly mix it with ordinary tools such as a paddle, and the use of such ordinary tools causes slopping over of the paint and consequently considerable waste.

The object of my invention is to provide a simple, inexpensive and very eliicient tool which can be readily inserted into a receptacle and which can be readily rotated or otherwise manipulated by hand to quickly break up the settled paint body and thoroughly mix it with the oil or other solvent without spilling it. The tool of my invention comprises a handle and a number of blades, the blades being readily stamped integral from sheet material and so shaped at their upper ends that they can be readily inserted in the lower end of the handle.

The details of my invention will be clearly understood by reference to the accompanying drawing, in which Figure 1 is a side elevational view of the improved tool showing it inserted in a can, and the method of operating,

Fig. 2 is a side elevational view of one of the blades,

Fig. 3 is a side elevational view of the other blade,

Fig. 4 is a sectional view on plane 44,

Speeification of Letters Patent;

ce'iving the lower part of the blade 6 and the slot 16 receiving the upper part ofthe; blade Z). After the blades are thus brought together their shanks are inserted into the lower end of the wooden handle 10 and to further secure the blades a ferrule 18. is provided in whose base are the cross slots 19 and 20 at right angles with each other, through which the blade shanks pass. Through holes 21 in the ferrule sides tacks or pins may be driven into the wooden handle to secure the ferrule to the handle.

In Fig. 1 the tool is shown inserted into a cam 0, the blades at their bases being of a width to fit the cam diameter and the width of the blades at their Wings 13 and 14 being sufficiently less so that the blades will clear the top flanges of the can, which flanges remain after cutting open of the can or serve as a seat for the slip covers. When the tool is inserted the blades of course first engage with the top of the settled paint body. By rolling the handle 10 between the hands the blades will quickly work and cut their way down into the paint body and will break and loosen it up. The lower ends of the wings are cut diagonally so as to leave cutting points 22 and 23 which assist in cutting up the paint, while the diagonal openings 24 and 25 between the wing ends and the conical sides of the blades will cause upward circulation as the tool is rapidly rotated, this bringing the paint particles toward the surface of the can into the oil and into the path of the wings so that these particles will be rapidly rotated in the oil and quickly disentegrated and dissolved.

In order to adapt the tool for cutting open paint cans the blade I) has the sections 26 and 27 deflected laterally from the wings. To open a can the lower pointed end of a wing 15 or 14 is forced through the can to until the corresponding projection 26 or 2 'rests on the can rim and by then working Patented Oct. 15, 1918.

tool which is particularly useful for cutting up and "mixlngpaint. The blades can be readily formed integral from sheet metal and can be packed fiat for shipping pur- 'poses.' "They can be readily assembled and inserted in thehandle and when the tool is rapid'ly revolved the settled paint is quickly copies of this patent may'be obtained for broken up and thoroughly mixed with the oil without spilling over.

I-do not" desire to be limited to the exact construction and arrangement shown as changes are no doubt possible which would "still come within the scope of the invention.

I claim as follows: 1. A .paint mixing tool comprising a handle, and ablade having a dovetailed lowersection, and wings above said lower section.

'2. A paint mixing tool comprising a handle, two sheet metal bladessecured in the lowen'end of-said handle at right angles with each other, the lower sections of said blades being dovetailed ,andside wings on said blades above the-lower sections thereof.

3. A paint Ini-X-ing" tool blade having a dovetailed lower end and wingsia'b'ove said end.
