PAINT STIRHER Filed Aug. 15, 1929 to be supplied Patented Jan. 19, 1932 SAMUEL 1i. GIBSON, oF-LAKnwoon, oiifo, ms compan or CLEVELAND,

PA NT,- sr rmtnn i V hpplioation filed aiigiistfiai'eae; se ms. 386,199.

This invention relates "to paint stirrers,

and more particularly to devices of this'cha'racter adapted for manual operation to give a final stirring to ready-prepared paint just before the, application thereoff'to theisurface to-be painte A substantial part bf the' 'market'forlpaint have little or or home userswill buya can. of paint 'from the local store, P color chart, and I then before", applymg the paint merely stir it a few times with a" stick or other home-made implement." As aresult, an'inferiorefl'ect is produced when v the poorly mixed paint is applied to the surface, as it will not be of uniform consistency,

causing a mottled surface which will cgenerally vary considerably in color from that of the color chart. Upon complaintTto'the vendor that the paint did not correspond to the color chart, an experienced painter is often sent out by the store'who will properly mix the paint and produce a paint surface which exactly coincides with the colorichart, "proving that the entire difficulty ism the final stirring of the paint. I, 7 In order to "cope with this problem =1t 1s proposed toprovide a simple;paint stirrer which may be used'by aninexperienced painter, which will thoroughly mix thepaint so that the desired efiect may be produced. By economical manufacture, these stirrers may be supplied gratis by the vendor with each can of paint. 7

The present invention has'to do with this problem and has for its general-object-to simplify andimprove the construction-an operation of devices of -this character,

A specific object of the invention is toprovide a paint stirrer which will thoroughly stir the paint at the bottom of the can and permit the paint thrown up Ifromithe bottom to "overflow the stirrer at the top without "spilling out of the can. 7 r

"Fig. 45' is 'an elevation showing a modified construction of the paint stirrer. V

Y 1 Referring more particularly to'the drawings, thep'aint stirrer comprises, essentially,

a handle-10 and a, blade .11; The handle 10 comprises a vertical shaft, thefilower "portion of which is substantially straight. The

upper" oportion offthe shaft 10 is bent laterally'as at 10,fthen vertically upward as at "12, again laterally as atfllS, and finally ver- F:

The outer cornersof the blade ll-may be cut away asat 15 so that the lower determined; slightly less than the diameter oftheqpaint canj173With which it to be portions of -the" sides will be perpendicular to the-base Thewidth of thebase 16 is prehas the further advantage that the portions I 15 may be used to scrape the sides of'the can bymerely elevatingthe stirrer during rotation thereof.

The blade 11 perforated by a plurality of apertures 18 which are preferably-distrib uted along the bottom and side margins of the blade. These apertures facilitate the mixing of the paint inan obvious manner. The blade is rigidly secured to the shaft 10 by any desired means,which in the embodiment shown comprises rivets '19.

preferred shown in Figs. 1 and 2 a second blade '20 is p asses throug .Zontal plane but at of each blade are .plate 11 reversed .may be punched alike,

7 The above description applies equally to each of the figures of the drawings, but in the embodiment of the invention provided on the other side'of the shaft 10, the shaft holding the blades in spaced relation. The blade 20 is preferably parallel to and similarto the blade 11 with the excep-- tion that it is provided with apertures 21 which are apertures 18 in the blade 11, but preferably in overlapping relation therewith. This arrangement provides that each of the blades willpresent' a different surface, of revolution and thus effect a more thorough stirring or cutting of the paint, as the paint which h theapertures 18 cannotpass undisturbed through apertures 21.

While the disalignment of the apertures 18 and 21 may be provided in various ways, it will be noted that in the specificembodiment, the corresponding holes are in the-same horidifierent distances from Hence the holes are at different distances from theadj'acent side edges, being oifset in the direction of the centrifugal force set up by the stirring.

It will be noted that theholes of one side respectively spaced as distances from the shaft 10 and the side edge, which are different from the corresponding distances of the opposite holes in the other side. An economy of manufacture islprovided thereby as the plate 20 may be merely a Thus all plates ll and 20 and the disalignment taken care ofduring assembly by merely rethe axis of rotation.

When ready-mixed paintfhas been, on the shelf in the can for an indefinite period the heavier ingredients thereof will settle to the tation of the material at the lower portion of the can will throw it upwardtoward the located out of alignment with the shaft apertures of. one alignmentwith the apertures of .the other.

Thus, in mixing, it is quite import ant thatvthe surface of revolution cover substantially the entire bottom of thecan. Agiedges. from. the corresponding upper portion of the can. The tapered sides of the blade '11, or the blades 11 and 20, will permit the paint thrown up from the bottom of the can to overflow the blades in passing, and such overflow will cause an additional agitation of the paint.

It will] be obvious that the specific structure shown and described is susceptible of very many modifications within the scope of the broader idea thereof. It is, therefore, to. be understood thatthe scope of the invention is not to be limited to the details shown and described but includes such embodiments of the broad idea as fall within the scope of the sub-joined claims.

Having thus described the invention what I claim as new and desire to secure as Letters Patent of theUnited States is: i

, 1. A, paint stirrer comprising a vertical shaft,- nd blades securedadjacent their intermediate portions toeach side ofjthe lower portion of said shaftand spaced apart thereby, there, being a single integral perforated blade oneach side of said shaft.

2. A paint stirrer comprising a vertical jacent their intermediate portions to the 0p- .posite sides of the lower portion of said shaft, each of said blades being providedwitha plurality of apertures, on each side of said blade being out of 3. A paint stirrer comprising a vertical shaft, blades secured to the lower portion of said shaft, each of said blades being provided with. a, plurality of apertures, the apertures, of one blade being out of alignment with the apertures of the other but in overlappingrelation therewith. I Y I 4. A paint stirrer adapted to stir paint in a can, c0mprising ajblade' having a lower edge adapted to conform to the bottom of a paint can and extend toward the sides thereof, and

having side edges extending upwardly from said lower edge and inwardly from the sides:

of: the can. topermit the paint thrown up from the bottom, of the can to overflow the upper portion of the blade, without spilling out, of-the can, said blade havin-gapertures spaced from one side edge, and other apertures spaced; different distances from the other side edge.

5. A paint stirrer comprising a vertical shaft and a plurality of parallel blades connected thereto, each of said blades being perforated-in. the-same pattern, the perforations of one blade being at different distances from the shaft from the perforations of another blade. i 1

6. A paint stirrer having a'blade'adapted to rotate about a vertical axis, and provided with holes in each side, the holes in one side being at different distances from the side holes of the Q other side and an identical blade reversed with respect to-the first mentioned blade.

7. ,A paint stirrer having a plurality of 7 blades adapted to rotate about a vertical axis,

. and each provided with a plurality of eccentric apertures, one of said blades being re versed, whereby the apertures therein are disposed at different distances from the axis of rotation from the corresponding apertures of the other.

8. A paint'stirrer adapted to stir paint in a receptacle, comprising a blade rotatable about a vertical axis, and having a straight lower edge adapted to contact with the bottom of the receptacle for substantially the full diameter thereof to dislodge paint therefrom, said blades having a plurality of eccentric a'per tures, the upper edges of said blade converg- I ing thereabove, whereby rotation of the blade.

causes the paint dislodged by said lower edge to swirl over said converging upper edges and cooperate with the orificeeffect of said apertures to cause rapid'mixing of the paint. 7

In testimony whereof, I hereunto affix my signature, SAMUEL I-I. GIBSON.
