FRED B. STOCKMANN, OF CINCINNATI, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO MARGARET FRELINGER, OF NEWPORT, KENTUCKY.

AGITATOB 0R STIRRER FOR PAINT-BARBELS AND THE LIKE.

To all whom 'it may concern:

Be it known that I, FRED B. S'rookMAN N, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in Agitators or Stirrers for Paint-Barrels and the Like, of which the following is a speci fication.

This invention relates to paint mixers, or, more particularly speaking, to the agitating or stirring devices used in barrels, kegs, cans or like receptacles for paint that has been already mixed, or for other liquid compounds that contain heavy matter or sediment that has a tendency to settle to the bottom when at rest.

The object of the invention is to provide a stirring blade or paddle of a single sheet of metal or other suitable material that is not likely to affect or be affected by the contents of the receptacle, such single piece of material being bent and shaped into form with due consideration for both lightness and strength and, also, for use in causing the settlings to readily rise in the liquid for thorough admixture.

In the single sheet of drawings, forming a part of this specification, Figure 1 is a vertical section of a barrel showing my im proved agitating or stirring device in operative position therein; Fig. 2, a fragmentary, vertical section, partly in elevation, showing the bottom-head of the barrel (omitting the barrel itself), the lower portion of the upright shaft of the device, the lower bearing for said shaft mounted on said bottom-head and the stirring-blade mounted on said lower portion of the upright shaft, all on a somewhat larger scale than that of the same parts seen in Fig. 1; Fig. 3, a plan view of the stirring-blade that forms the principal feature of my invention herein, such blade bein detached from all the other parts of the device excepting the upright shaft, the latter being shown in cross-section; Fig. 4, a plan View, on a reduced scale, showing the blank strip or piece of sheet-metal used in formin' my improved stirring-blade, the dottedlines indicating those on which the blade is bent and shaped into the form seen in said Fi 3; and Fig. 5, a fragmentary section of t e head or to of the barrel showing a safety-plug used in the center thereof for closing the shaft aperture when the Specification of Letters Patent.

hand-crank has been removed and when the barrel is to be closed and handled.

In these views, 1 indicates the barrel or receptacle for the paint or other solution to be held therein.

2 indicates the bottom-head and 8 thetophead of the barrel, the top-head having a central aperture 4 and the bottom-head having a central step or raised bearing-piece 5, the latter being suitably secured by means of screws or the like 6 on the inner face of the said bottom-head.

7 indicates an upright axial shaft centrally-disposed in the barrel, with its lower reduced end 8 bearing in the central aperture in the raised portion of the bearing 5 and passing upward through the central aperture 4 in the top 3, a centrally-perforated plate 9 being secured concentric to the outer face of the head 3 over the aperture 4, as best seen in Fig. 1. The plate 9 is removably-attached in place by screws or the like and forms a wearing surface for the said aperture 4 in the top of the barrel and so that the upper part of the shaft turns free of said aperture 4.

10 is a hand-crank removably-attached to the upper end of the shaft 7, for driving the latter.

A cotter-pin 11 is placed in the lower re duoed end 8 of the shaft to prevent the latter becoming disengaged from the bearing 5 in use. This cotter-pin enables the ready separation of the shaft from the bearing 5 when desired and is readily inserted owing to the opening provided in the raised portion of said bearing. The lower end of the shaft is raised above the inner face of the bottom of the barrel so that there is no undue wear or friction.

The most important feature of my inven tion herein lies in the construction of the paddle or agitator. This agitator is a horizontal one and is made of a single sheet of metal cut into the form seen in the blank m, Fig. 4. This blank is split at y, perforated with a small hole at a, and, also, perforated with a square hole at s, the purposes of which will be now described.

The agitator blade or paddle is composed of the body portion 12 having at its opposite ends the flaring arms or wings 13 and, also, having along its horizontal upper edge an integral flange 14 bent laterally outward horizontally.

In Fig. 4, it will be seen that the flange 14 is bent on the dotted-line 14" and the flared wings 13 are shaped along the oblique dotted-lines 13 The shaft 7 is preferably square in crosssection and passes downwardly through the square aperture 8 in the flanged portion 14 of the blade and thence downward in contact with the body portion 12 of the blade, to and through an opening or guide-way provided by upsetting or outwardly-turning the metal y in the split portion y of the blank. The lower edge of the blade .is elevated slightly above the raised portion of the bearing 5, as best seen in Fig. 2, so as to properly clear said raised portion of the bearing in rot-at ing, and a rivet 15 is provided to suitably attach the blade in place on the shaft, and, also, as best seen in said Fig. 2, the said rivet passing through the perforation z of the blank m after the blank has been duly shaped.

It is important that the blade be made of a single sheet of metal and provided with the flange 14:, together with the

integral wings

13, 13, so that .its manufacture is simple and economical and so that there are no loose parts to get out of order or become detached and, also, so that such blade can be readily attached in place by means of a single rivet at the lower end of the shaft and securely held in position free from lateral or torsional movement on the shaft and is adapted to stir and force the sediment or heavy material from the bottom of the receptacle into solution or thorough circulation with theliquid contents of such receptacle.

The safety-plug, seen in Fig. 5, is another important feature of the invention herein, for the reason that it is to be used when the hand-crank 10 is removed and the barrel is to be tightly closed for any desired handling thereof. This safety-plug is composed of a closed head 16 having a flange or base 17 and a lower, extended screw-threaded shank 18, such shank being adapted to be readily turned or screwed into the aperture 4 of the top-head 3 when plate 9 has been removed, the hollow or elongated cavity 19 of the plug being adapted to receive the upper end of the shaft 7 and to hold the stirring mechanism in proper position. None of the contents of the barrel can escape when this plug is in place and it is readily removed when it is desired to use the stirring or agitating devices.

An outlet-faucet 20 is provided at the bottom of the barrel for use in withdrawing the contents at will and is a feature common to paint-mixers.

It is obvious that a number of addles or blades such as the one shown, can e mounted on the shaft 7 at suitable intervals apart l above the blade already shown in Fig. 1, for the purpose of expediting the admixture or circulation of the contents, especially when the settlings are of a very heavy nature, such as is paint itself that is mostly concerned herein. A series of paddles or blades constructed on my plan can be readily attached on the shaft and at comparatively small expense taking into consideration the effective result accomplished on said heavier ingredients.

I claim:

1. A stirrer or agitator device for paint barrels or the like, the same comprising a single sheet of metal having a flat body portion, made integral flaring wing portions at the opposite ends of such body portion but within the length thereof and a horizontal flange or forwardly-projecting portion along the upper edge of said body portion.

2. A stirrer or agitator device for aintbarrels or the like, the same comprising a single sheet of metal having a flat body portion, madeintegral flaring wing portions at the opposite ends of said body portion but within the length thereof, a horizontal flange extending along the upper edge of said body portion, an outwardly-extended eye-portion centrally made in the lower edge of the body portion, an aperture or guide-way pierced in the center of said upper flanged portion and means comprising an upright shaft for supporting said blade for rotation within a paint-barrel or the like.

3. A stirring or agitating device for use in paint -Inixers or like receptacles, the same comprising an upright shaft, a raised bearing within the lower or bottom portion of said paint-mixer or like receptacle for receiving the lower end of said shaft, a cotterpin in the extended end of said shaft below the raised portion of said bearing, a stirring-blade horizontallyextended at the lower end of said shaft above the said bearing and made of a single sheet of metal with oppositely-flaring wings and. a horizontal flange, a rivet for securing said blade to the shaft and a driving hand-crank removablyattached to the upper end of said shaft.

4:. A paint-mixer having therein a vertical shaft and a horizontal blade or paddle, a top-head having a central aperture for the outwardly extending portion of said shaft and a hollow safety-plug having a closed head, a flanged base and a screw-threaded lower extended shank portion adapted to close said aperture and receive the upper end of the shaft when the device is not in use or to be handled in transportation.
