ROTATABLE AGITATO R AND 'SCBAPER.

Application filed my 25, 1927. Serial No. 194,004.

My invention relates to a device to be installed upon or within a can of paint or the like, to properly stir or mix the contents of the same.

In accordance with my invention, I provide a mixing or stirring element, adapted to be turned or rotated, and which is collapsible, so that it may he conveniently inserted within the can. The device may also be partly or wholly eollapsed, within the can, to assume a position out of the way, when it is desired to dip a paint brush into the can. The device may thus'be applied to a can of paint and Will not interfere with the insertion of the brush into the can, during the ordinary painting operation. The device also embodies a cover member, carrying or supporting the rotatable stirring element or agitator. This cover member is preferably provided with a spout so that after the paint has been thoroughly stirred or mixed in the can, it maybe poured or transferred into another can, without liability of spilling the paint. The cover member'is so constructed that it is adapted to have engagement with strainer element or elements, so that paint from a partly used can ofpaint may be poured back into the can carrying the stirrer oragitator andallgrit or solid material will "be removed from the paint. The device is adapted to be applied to the standard p aint can, upon the market, and may be made in anysuitable size, depending upon the size olithe cantor which it is tobe used.

Other objects and advantages of the invention will be apparent during the course of the following description.

In theacoomp'anying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

In the drawings, wherein for the purpose an edge elevation of the same,

- of illustration, is shown, a preferred embodiment of my invention, the numeral 15 desig na' a paint an, of the standard type, now upon the market. This can 'is provided at top with the usual inwardly projecting flange orri'b 16. The can 15 may be of any selected size, such as a gallon, quart, pint or half 'pfl'nt.

My stirring or agitating device elnbodiesa cover member, including continuous an'nw lar body portion 17, of "the psoper size to en snuglyove-r'th'e top oft 'e can 15, While itisp'referred to construct the annular body portion 1'? of the proper size to lit the can,

yet, I contemplate having the member 17 circumterentially adjustable. The annular body portion is provided at its upper edge with an inwardly projecting horizontal "flange 18, arranged above and overlap in the flange 16. A packing element or washer 19, formed of rubber orthe like, is cemented or otherwise suitably attached to the bottom of the flange 181,1andis arranged to engage with thefiange 16 of the "can, for effecting an air-tight joint. Rigidly attached to the horizontal flange 18 of the cover member is an upwardly project-- ing spout 20, preferably formed inte ral therewith. This spout extends for less tian one-halfof the circumference o'ithe flange 18. The spout is employed in pouring the con tents of the can 15, into] another can, as will be more fully explained.

The numeral 21 designates a cover element or plate, included in the cover member. This cover element or plate is segmental and covers more than one-half of the area of the flange 18. The segmental cover element is fiat and is pivoted at one end, by means of a pivot element .22 with the flange 18. The cover element is, therefore, adapted to swing horizontalJ-ly in sliding contact with the top of the flange 18. The-segmental cover element 21 is provided upon its inner straight edge, with a vertical fla'nge'23, preferably integral therewith, and this vertical flange has {one end thereof positioned adjacent to and inwardly of the spout orfiange 20,'while its opposite end is provided with a resilient catch '24, to engage over a head 25, formed upon the opposite end of the spout 20. The flange 23,

, therefore, constitutes the. inner side of the spout, as shown. The fiat segmental cover element 21 is provided with adown-turned flange 26 having a plurality of horizontal, slots 27, which are; adapted to receive hori zontal stationary bolts 28, rigidly attached to the annular body portion 17. 1 These bolts have t-heiredges beveled at 29, so that they will readily enter the slots 27, upon the horir-sontal movementiof the segmental cover ele inent 21. Thebolts and slotted flange serveas means'to lock the segmental cover element 21 to the annular body portion 17,"

against vertical movement, thus holding these parts in close relation, for effecting a substantially air-tight joint. i

The device embodies a stirring or agitating member,comprising a verticalrotatable shaft 30, projecting into the can, and having itsupper portion extending eXt-eriorly of the cover In-en ber'and rotatablewithinan opening 31 *formedin a bracket 32, carried by the top edge of the flange 23. The shaft is also rotatable within an opening 33, formed in the segmental cover element 21. The shaft30 carries a stop collar 34, rigidlydetachably attached thereto. The upper end 35 of theshaft 30 is formed polygonal in cross section for detachable engagement with a crank orhandle 36 to turn the shaft.

a. The agitating member embodies anagitat- 'ing element or plate 37, which may be formed of metalor the, like, andstamped to provide a longitudinal strip 38,and radial arms 39.

These arms are provided at theirinner ends withsleeves or hubs 40, which are rigidly attached to the shaft 30, for rotation therewith.

The hubs 40 are provided upontheir sides remote from the arms39 with generally radialshifting flanges 4l, rigidly secured there- I to. Theseshifting flanges are thusarranged upon the leadingsides of the hubs or sleeves 40." The agitating member further embodies an agitating element 42, formed of metal or the like, stamped toprovide outer and inner longitudinal strips 43 and 44, connected by radial portions 45. Secured to the longitudinal strips 44 and alternately arranged upon theshaft 30, with respect to the hubs 40, are knuckles 46, pivoted upon this shaft.

The strip 44 is arranged in advance of the is thus seen that when theshaft 30 is turned shifting elements orfianges 41, as shown. It

When it is desired to use the can with the stirring or agitating deviceapplied thereto, for painting purposes, as by dipping the brush into the can, the segmental cover element Qlis swung to the open position, Figure 1, the agitating member being first rotated to the position shown in Figure 4, so that it will fold or collapse, upon shifting the shaft 30 laterally. The swinging of the segmental cover element 21, to the open position, greatly increases the size of the opening at the spout 20 and the rotatable agitating or mixing element is arranged adjacent to that side of the can remote from the spout, and hence out of the way. i

If itis desired to introduce paint from other cans, into the can 1 5, for proper stirring or agitation, the cover member may assume the closed position, and the strainer 54 placed Within the spout. Further, the segmental cover element 21 may be shifted to the open position, Figure 1, and the strainer element embodying the frame 57 inserted within the spout. This provides a strainer of greater capacity.

It is to be understood that the form of m invention, herewith shown and described, is to be taken as a. preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention, or the scope of the sub-joined claims.
