CHARLES E. EARRINGI'ON,- OF EHILADELPHIA, PENNSYLVANAV 'j AGI ATO HAND LEQ y Application filed February 28, 1920. Serial No. 362397;

To all whom it may concem: i

Be it known that I; C ARLES' E. FARRING- TON, a 'citizen of the United States, residng at Philadelphia, in the 'county of Philadelphia and State of Pennsylvanimhave invented new and useful Improvements in Agitator Handlesof which the following is a specification. i

This invention has for its object to provide a handle for various uses but more particularly for the employment with barrel agitators, such for instance as illustrated in my application for Letters Patent, Serial No. 251,'786, filed August 28, 1918.

The invention comprises an' arm 'which may serve as a lever for rotating a member, such as a shaft or agitator, and a pin extendinglaterally from the end of the arm, which will serve as the, crank to 'be grasped by thehand. The pin is detachable from the arm, an`d, when not in use, is clamped in a groove' or slot formed in the arm, by securing the arm by suitable fastenings a, the head of a barrel. Thus the pin m b'e dismounted and secured in its clamped position when the handle as a whole is not in use or is to be shippecl. The arm; when used for efi'ecting the rotation of an ag itator, may be formed with an enlargement to serve as the cover or closure of a hole in 'the head of the, barrel, and may be pro vided with 'means to project into the hole for detachably engagng the end of the agitator which is located within the barrel.

`On the drawings,-

Figure '1 represents. infsection the upper end of a barrel containing an agitator, and' provided with' a handle embodying my in vention. e u i v Figure 2 represents a plan view of the arm with the ,crank-pin clamped in inactive position.

Figure 3 represents, on a largerscale, the arm with the crank-pin in inactive position. Figure 4 represents a cross-section on the line l-t ofFigure 3.

Figure 5 represents a section on' the line 5-5 of Figure 3.'

Figure 6 represents alongitudinal section through the arm with the crank-pin located in its active or operative position\ i Referring to the drawings,-I,have .illus-.

t rated in Figure 1 the upper portion of ta wooden barrel 10 having ahead 11. Within a substantially circular head 14. which serves I as a cover or closure for theaperturel in v i\ thecenterof the barrel head l l. The arm 13 is formed with an angular portion ;16 connecting thehead oricap 14 with thebody ofthe arm, so that thelatterliesin aplane spaced or separatedfrom the plane of the i barrel head. The outer extremity of the arm hasa dependen-boss l? which termii nates short of thebarrel head, and which has a threaded aperture 18. As shown in Figure 3, the circularheaid' hasin itsunder facecircular groove .19 to receivea packv ing ring 20 .of rubberor other'suitable mai terial, and it also has ears 21 which are apertured at 22, as shownin Figurea An point w equi-distantfrom the apertures 22', and through these thrceapertures 22, 22, 23,

. Inasmuch as the arm andtshead maybe .utilzedto effect the rotation 'ofthe agitator,

the head or cap isformedgwith depending e i clutch members which :project into the apel"- ture 15 and form a journal engagngthe wall of said aperturei which serves` as a hearing `therefor. 'Said mem'bers likewise are constructed to engage" the upper; end 'of the. agitaton blade; As shownythe clutch i members may be three in number: as indicated at 24:, Qi, 25. 'The member25 'andone 'ofjthe members'24c lie on one side of the agitator blade, and the' other member 24: {lies-won the other-side, sothat, when the arm is rotated e e.

a clockwi sedirection,' it ;will rotate the bla e; t, he t e arm ,is` rot tedn th reverse direction, the rotation of the blade is not properly e'l'ected. The reason for this is that ordinarily the blade, to accomplish its functions most effectively, should be rotated in a clockwise direction only. Of course, the member' 25 could be duplicated on the opposite side of the blade, so that the blade could be rotated as readily in one direction as in the other. The outer walls of the lugs or members 24-, 25, have a cylindrical curvature about a common center, so as properly to engage the cylindrical wall of the aperture 15.

The arm is provided with a crank pin by which it may be rotated, but which, when not in use, may benested in a recess in the arm. This pin may take any suitable or desirable form. As shown, it consists of an elongated stud 26 andcprovided at its opposite end with a screw thread 28 to enter into threaded engagementwith the aperture 18 in the end of the arm 13, and a sleeve 29 which encloses the stud. The constructon thue 'described permits the sleeve to be moved to an eXtended position and to have a freedom of movement when 'it is grasped by the hand, in the act of revolvng the stud about the aXis of' theagitator.

If the crank pin were permanently fixed to the arm,-it is evident that, in 'transporting the barrel, it would be easily broken or injured and would prevent the close packing of the barrels, and hence the crank-pin is detachable. Iprovide for assembling the pin with the arm in such manner that it cannot be lost in transit. For this purpose, the arm 13 is formed on its under side with a recess in which the pin may be nested and clamped against the top of the barrel. This recess may take the form of a slot 31 having beveled or concave side walls 32 for engaging the cranlepin. The slot is longer than the stud or sleeve, so that the crank-pin may be'nested in the recess between the arm and head of the barrel, and thus be clamped between the last-mentioned parts.

In practice, the agitator may be located within the barrel, and the head or cap of the arm (with thepacking 20 in place) located overthe opening 15 in the head of the .barrel, with the clutch members 24, 25, engaging theend of the agitator. The crank-pin, which is then detached or dismounted, is placed in the recess in the arm, and Wood screwsor other fastenings are passed through the holes 22,-23, so as secure ly to fasten the head in place and to tightly close the opening 15. The crank-pin is thus securely clamped' against' dislocation in the recess,

'and between thearm and the barrel. If desired, a fourth wood screw may be driven through 'the' aperture 18 in the end of the arm into the head of the barrel, but this ordinarily isunnecessary, `When the barrel 'a'r'rives `'at' its destination, the wood screws are removed, the crank-pin is secured to the end of the arm by screwing the stud 26 into the threaded aperture 18, and the arm may now be moved about its axis to operate the agitator.

Of course, other suitable meansmay be cmployed for securing the handle in place. In fact, the cap be threaded to screw into a threaded opening in the head of the barrel or container, as shown in my said copending application.

It will be noted, from an examinaton of Figure 1, that, when the crank pin is nested in the recess in the arm and thereby clamped in place, all portions of the arm are located below the plane at the edge of the chine of the barrel, so that "there is little likelihood of the arm being broken or otherwise injured.
