CHARLES n. FARnING'roN, or PHonNrxvi'LLn, PENNSYLVANIA.

BARREL nerrn'roa.

Application flied May 22, 1924. Serial No.` 715,095.

To all whom t may concern Y Be it'known that LCHAnLnsE. FARRING- TON, citizen oftthe United States, residing at PhoeniXville,'in the county oi? Chester and State ot Pennsylvania, have invented new and useful Improvements -in Idarrel Agitators, ot which the following is a specification. Y

This invention relates `to agitators for stirring the contents oil a barrel or drum wherein such materials as paints andother i suspensions or mixtures of various materials may be confined. In my Letters Patent No.

`1,336,830 dated April 13, 1920, I have disclosed an agitator consisting of a `blade which is rotatable about an anis approximately coincident with the barrel or drum, and which is provided with a weight pivoted upon a radial portion o1 the blade to l swing outwardly and operate in theangle formed by the bottom and side Wall of the container.

I have found in some cases, that even with the device described, it is ditlicult' to loosen and mix with the remainder of the contents of the tank, the solid or more viscous sedi.` ment or material which forms and is apt to cake on the bottom of the tank and in the angle referred to, and further that, when the bottom of the tank becomes malformed because of rough usage and depressions are i formed therein, the diliiculty increases. The l present invention has for its object to provide means for more eiiectlvely removing the 4sediment or deposit at the bottoni and in the angle of the tank. m

On the drawing,- l

Figure 1 represents in vertical section. a barrel provided with an agitating device embodying my invention.

Figure 2 represents a horizontal section through the same on line 9,-2 of Figure 1.

Figure 3 represents in section the bottom portion of a wooden barrel, and shows the flexible scraper in operation.

rFigure 4 shows how the scraper will operate if the end ot' the barrel or drum be deformed.

The container may be barrel-shaped or it may be cylindrical, and has, of course, a side wall 11, and the two ends 12 and 13, with the reentrant angle 14 formed by the `bottom 12 and sidewall 11. Any suitable stirrer may be employed having a radial arm o, movable about an axis substantially the container.

coincident with the anis of the container in approximately horizontal planes parallel with and adjacent to the bottom 12. Pret"- erably the stirrer consists oit a single thin rigid blade v14,0 comprising in addition to la' the arm o, which is cdgewise vertically, and the upwardly extended twisted portion b having its extremity c engaged with a member `15 by which the blade may be rotated by the use of a suitable detachable handle. At its inner extremity, the portion or arm a is pivoted on a stud secured in the center ot the bottoni 12. rIhe outer end of the arm a connectsy with the upwardly extending portion b `by a bend or twist cl. These feat tures, which are all disclosed in my said Letters Patent, may be varied, however, as occasion demands.

The present .improvement resides in a iexible scraper which preferably takes the form of a relatively heavy metal chain formed of a series ot links, as indicated at 17, rand `having one, extremity secured at or near the inner end ot the agitator arm a, and its other extremity secured at or near the outer end of the arm,-in the present instance in the bend cl. Anysuitable means may be employed for securing the end links ot the chain, such as hooks 18, engaging eyes 19 attached to the arm o. The chain is considerably longer than the distance between the eyes 19, so that normally the intermediate part of the chain rests loosely upon the bottom of the container, as shown in Figure 1. By rotating the agitator slowly about its axis, the depending intermediate portion oi. the lienible scraper scrapes along the bottom 12 and extends into depressions in the bottom, as shown in Figure 4, so as thoroughly to loosen and remove any sediment or deposit onthe bottom; and then by rotating or revolving the agitator at suliicient speed to subject the vflexible scraper or chain to centrifugal action, the latter will be caused to scrape along the surfaces at the angle formed by the bottom and the side wall oit While a relatively heavy chain isthe preferred forni of the invention, any equivalent, which when suspended at its ends will torni a catenary curve, may be used provided it is ot sufficient weight and flexibility to function.

That I claim is:

1. `An agitator for a barrel or like'container, comprising an arm revoluble about the axis of the Container :rnd extending outwardly freni seid exis toward the side Well iii" said container and thence upwardly, and zi flexible scraper having its ends attached to the erin Lind depending therefrom, so as to be drugged therebjyv over the bottoni of the container when the erin is revolved, sneh i formed by seid bottoni and the Ieide well et seid container.

An agitator for :i lbarrel or .like eon tniner, comprising nn zirni revolnhle about the exis of the container und extending oniwzrrdly from said axis toward the Side Well oit' seid container, and thence upwardly, und u flexible eernper having one end nttziehed to the inner end oit the nrni und its ether end to the npn'urdLv extending.;l enter pei-- tion oi seid erin, andidepmnlingir thereifrtnn, so :is to be dragged over the lioteinet the ,Container when the erin is revolved, isnif'l scraper being' el ,euch length that its interinediate portion muy operate in the tingle termed by the bottoni :1nd the Fide mill el' the container.

In testimony whereof I have eilxed my; signature.
