EGG BEATER AND DRINK MIXER.

Application led March 26, 1924, SeriallNlo. 702,072. Renewed May 5, 1926l My invention relates to egg beaters, drink mixers and similar articles for agitating liquids and aerating them, and has for its object to produce an article of this kind that will quickly and thoroughly agitate, aerate and mix any liquid or semiliquid substance that may be treated there- In the accompanying drawings:

Figure l is a side view of an article embodying my invention.

Fig. 2 is a central vertical sectionof the same.

. Fig. 3 is a perspective view of the cover and associated parts separated from each other. Y

Referring to the drawings, 2 designates a vessel that serves as a container for the liquids to be treated. It is preferably formed of glass'and is of elongated cylindrical shape. Its upper end is open; and near such end the vessel is formed with an external flange 3,` above which extends the cylindrical rim d which preferably tapers slightly towards its upper edge. The glass or other material of which the vessel 2 is formed is preferably slightly thickened on the inside as represented at 5 for a purpose which will be described.

6 represents the cover of the vessel 1t is formed of metal and comprises a horizontal plate 7 at the edge of which is a folded rim 8 that risesiabove the plane of the plate 7 and forms a groove adapted to lit the rim 4c when the cover is applied. v The lower edge of the outer fold of the rim '8 is adapted to rest uponthe upper edge of the flange 3 when the cover is properly applied;

and the annular groove formed in the rim tapers upwardly and is of such width that when the cover is applied there is a close, and practically air-tight, fit between the rim 4 and the folded flange ofthe cover.

The horizontal plate of the cover is perforated at 9 to form breathing openings through which atmospheric air freely passes to and from the interior of the vessel 2 during the operation of the article. y

10 designate a rod adapted to pass centrally through the cover 6 and carrying dashers or agitating plates 11 at its lower end. These may beV of any preferred con struction. I prefer to provide two diskr shaped perforated metal plates spaced apart and of such diameter thattheir edges lie close to the interior wall of thevessel 2, to

serveas the dashers. The upper end of the rod l() is reduced and screw-threaded as at 12 to receive a head 13 by which the rod is manipulated. A coiled spring 14 encircles the upper endl of the rod, to `which it is united by causing itsupper convolution 15 to be clamped between the'head 18 and the shoulder at the lower end of the reduced portion 12 ofthe rod.

16 indicates an elongated hollow post that surrounds Vthe rod 10 below theV spring 1&1. To the upper end of this hollow post is secured a cross clamp 17 adapted to engage with the flange 3 of the vessel and hold the cover in place. VA collar 18, through which passes the dasher rod 10, is secured to the cross clamp 17 and serves as a bearing for the lower convolution of the spring 14. and also as a practicalv continuation of the post 16 above such clamp. The lower end of the hollow post is reduced in diameter and is externally screw-threaded as at 19, and passes centrallyV through the plate 7 of the cover. A hollow nut 20 engages-with the reduced screw-threaded end 19 of the post 16 and clamps the horizontal plate of the cover between its upper end and the shoulder formed at the upper end of the screwthreaded part l19 of the post, thus securely uniting the cover to the post, but permittino` ,its easy separation therefrom, as indicated 1n Fig. 8, for cleansing or other purposes. The nut 2O serves as a gland or box to receive a packing 21 that surrounds the dasher rod 10 and prevents any liquid from pass.- ing along the rod and out through `the hollowV post l16.

22 indicates an umbrella disk secured to the post 16 just below the plate 7 of the cover. It is centrally perforated` to pass over the reduced portion 18 of the collar 16 and is held in place against the underside of the cover by the nut 20. It is of such diameter that its edge Vbears against the inner wall of the vess-el 2 where itis thickened, at 5, thus preventing the liquid which may reach the upper portion of thevessel during the agitating process from escaping. The disk 22 is perforated at 23 to form breathing openings, these being so located as not to be in line with the breathing openings 9 in the cover. Any liquid that may pass through the openings 23 will be thus-arrested by the plate 7 of the cover and will fall back upon the top of the umbrella plate 22 and will thence iiow back into vthe body of ythe vessel 2 of the vessel either through the perforations substances, the mixing of drinks, in fact the 23, or escape aroundthe peripheral edge of the plate.

The manner of operating thearticle de-- scribed will be apparent. Suiiice it to say that when it is to be used the cover, dasher Y and associated parts are entirely removed,

and the liquid to be agitated is placed in the vessel 2. The cover is then replaced and clamped in positioin, the dasher resting near thebottoni ofthe vessel but not in contact therewith, being held at a suitable distance above such bottom byy the spring 14. The

operator now grasps the handle 13 and rapidly works the dasher rod up and down, the spring Y 111 preventing the dasher and lower end-of the rod 10 trombeing carried into forcible engagement with the bottomr of the vessel which might be cracked'or broken should this take place. The passage of the dashers through the body of liquid causes it to be broken up and violently agitated, thus eiiect-ing a thorough mixing `and aeration thereof, since there istree access ot air to the interior of the vessel, through the breathing openings 9 and-23. The liquid being agitatedy will quickly become a frothy mass of much greatervolume than that occupied by the kmaterial when first placed within the vessel. Some ot the material will Vthen inevitably reach the top of the vessel, but by the arrangements which I have de- -vised leakage thereotq is prevented. The engagement of the umbrella disk 22 with the thickened wall of the vessel 2 very eectively prevents the escape of the material around VKthe edges of such disk. The packing 21 Within the nut 20 prevents the escape of the liquid centrallyand along the reciprocating -dasher shaft or rod. The sealing of the cover by the tapering rim 4' entering and litting closely within the groove formed by the foldedrrini 8 prevents, without the use ot' a gasket,theescape of any vliquid that may pass above the umbrella plate 22. The nonregistering perforations tormed respectively inthe horizontal-plate of the cover and the umbrella disk insure free and ample supply of air to the interior of the body of the vessel, but do not permit the escape" of the liquid. If by chance any small amount vof liquid should pass the openings 9 it would.

collect in the cup formed by the up-standing rim 8 at the periphery of the horizontal plate 7 of the cover.

I have found it very important that there should-be a i'ree passage of external air to the interior of the vessel during the agitating operation to secure the desired aerating results, for wit-houtthese, as would be the case should the cover hermetically seal the vessel 2, I have found it impossible to properly beat and aerate many substances.

My invention can be :put to many uses, i Vsuch as the beating of eggs, cream, and' other agitation, mixing and aeration of practically I have shown the preferred form of my inventio'nVbutit will be understood that those skilled in the art inv practicing the same `are not to be limitedto tlie details herein shown, since these may be changed as circumstances suggest, so long as the principle ofmy invention is followed, which invention is stated in the following claims.
