.AG-ITATOR.

Application filed september 5, 1922. lserial No..5`se,234.

To all whom 'it may concern:

Be it known that I, EDWIN S. LEINAN, a citizen of the United States, residing at Fargo, in the county of Cass and State of North Dakota, have invented certain new and useful Improvements in Agitators, of which the following is a specification.

This invention relates to an improved agitator for culinary use Vin the beating of eggs, whipping of cream, and like operations.

rlhe primary object of the invention is the provision of an agitator which includes relatively few parts, which are compactly astively perform the use for which the same is provided.

An important object of this invention is the provision of an agitator including a knumber of dashers which includes a driving mechanism of adjustable character to compensate for wear upon the different parts thereof.

A further and important object of this invention is the provision of an improved agitator including a plurality of novelly arranged dasher members. A

Other `objectsand advantages of the improved agitator will be' apparent during the ycourse of the following detailed description.

proved agitator, showing several' parts thereof in section, in order to disclose the cooperative relation of the agitatorpdetails. Figure 3 is a fragmentary view, partly in section, showing cooperating parts of this invention. Y.

Figure 4 is a fragmentary cross sectional view, showing an adjustable View of 'the agitator operating mechanism.

In the drawing, wherein for the purpose of `illustration is shown thepreferred embodiment of this invention, the'letter A ge .n'erically indicates the improved agitator,

includingv a SuppOrtB; outer dasher arrangement C intermediate y'dasher arrangement D; inner dasher arrangement E and operating means F.

`nisn'rF to b'e subsequently mentioned. The

The support B preferably includes avflat 'Y metallic plate 10 vprovided with a recessy 11 eirten'dlng upwardly from the -lowerfmarginal'edge thereof and being provided with a transverse opening 12 adjacentthe oppo-z r site end thereof, said depression llitand opemng 12`being respectively provided `for accommodation of certain elements of the dasher arrangements C and D, whichwill be more specifically mentioned hereinafter.

The upper end of the supporting plated() is preferably provided with a looped handle"y y portion 14. sembled in adjustable relation to most effec- Referring, to vtheu'dasher arrangement C, the same includes a b'evelledpinion .'15 having a sleeve portion 16 formedupon one side thereof which :is circumferentially grooved for receiving a retaining collar-18,

which is clamped as by'rivets 19 to thesupi f porting plate 10. In'this relation, the, pinion is mounted in the recess 1l-of vthe 'plate '10,. bearing within the collar v18, 'and cooperating with certain parts of theguide mechaarrangement C furthermore includes thel dasher member 21 which is formed of wire or analogous material having certainspaced arms 22 which are connectedv` at their ends to thepinion 15, and depend in spaced parj allel relation-to support the loop23 of rigid" formation. j I

The intermediate dasher D includes a pinion 25, which isl provided with a. portionj26 extending outwardly therefrom grooved for receiving a bearing colla'r 27, said bearing'` collar 27 being secured, as byrivetsz2`8 to the same side of theyplate 10 asth'e :collar 18A is Vconnected to, andas is illustratedin Figures 1 'and 2 ofthe drawings. Ashaft BO extends axiallyfr'om. the portion 26 ofpin l ion 25, and depends throughtheaX-ial passageway Oafformed through the pinion 15;

saidshaft 30 being provided with the passageway v31 openingv from the` lower end thereof. The shaft 30 thus vextends between the arms 22 of the dasher member-121, and is provided with va ring shaped dasher 'end 32 upon thelower end'thereof which-is rela'- tively smaller in diameterthan the outer dasher ring v23,- so Ythat thefring 32 is'in fact, confined within the vrarea -of theJ loop 23. r.

It is to be noted, that the collar` retains the pinion 25 within theupperl opening 12.

The inner dasher is lof novel formation, and includes the plate portion'` 35 having certain apertures 36 therein to permit free passage of the liquid in which the agitator A is operated. The plate 35 is provided with a stem 37 extending outwardly from one end thereof bearing within an aperture 39 in the lower end of the dasher loop 32 and being affixed as by welding at 40 to the lower end of the outer baffle loop or ring 23. The plate 35 is also provided with `a stemp4l which extends opposite to, and aligns with respect to the stem 37, said stem 41 having an enlarged ybearing end 42 thereon, which is journalled within the passageway 3l of the shaft 30, so that the plate 35 is disposed within the area of the intermediate dasher loop 32, as is illustrated in Figure 2 of the drawings.

Referring now to the operating means F, the same includes a stub shaft 45, which extends from the surface 46 of the supporting plate 10, said `stub shaft 45 being screw threaded at 47 upon its free end for adjustably receiving athumb nut 43. A master bevelled gear 50 is provided having a polygonal shaped extension 5l axially at one side thereof, said gear 50 having an opening axially thereof for receiving the stub shaft 45, in order that the same may bear thereon. A crank 52 may be provided over the polygonal portion 51 of the master gear 50 in order to rotate the same upon the shaft 45. As is illustrated in 'Figure 2 of the drawings, the master gear 50 is so disposed upon the shaft 45 that the teeth there of are 1n engagement at opposite points with the pinions l5 and 25. The nut 43 may be so adjustedupon the screw threaded portion 47 of shaft 45 that the master gear 50 may be adjusted longitudinally of the shaft 45 for engaging the teeth of said pinions.

In operation, it is apparent that as the operator rotates the master gear 50, the pinions l5 and 25 will be turned in opposite directions for rotation of the

dasher loops

23 and 32 in opposite directions. Due to the fact that the inner dash member E is fiXedly connected to the loop 23 and bears within the intermediate dasherl arrangement D, it is obvoius that the oval shaped plate 35 will be rotated in the same direction as the outer dasher loop 23. This is a superior arrangement, since thereby an egg, or cream may be beaten in a relatively shorter time, and 1n a more effective manner than can be done with present types of agitators. It is well known, that agitators embodying the pinion drive arrangement soon become inoperative,

due to the wear upon the pinions and drive Y gear, as to cause slip of the teeth thereof.

This invention provides for such wear and for any loose bearings, by making the master gear 50 longitudinally slidable and adjustable upon its bearing shaft 45, so that the same may properly engage the pinions l5 and 25 1n operating relation.

From the foregoing, it can be seen that an agitator has been provided which while simple in operation is very durably oonstructed, embodying improved beating facilities, and improved adjustable assembly to compensate for wear upon the parts incident to operation.

Various changes in the shape, size and arrangement of parts may be made to the form of agitator herein shown and described without departing from the spirit of this invention or the scopev of the claims.
