EGGBEATER Application filed October 11, 1927. Serial No. 225,557.

The present invention is directed to improvements in egg heaters, although not nec essarily limited to such use.

The primary object of the invention is to provide a device of this character including a dasher of novel form, the construction there of being such that the material being agitated will produce a firmer, stifier, lighter and drier product than has heretofore been obtainable with conventional forms of heaters.

Another object of the invention is to provide a device of thiskind wherein the dasher is so constructed that the material will be momentarily trapped and aerated in its travel upward over the wings of the dasher, thus inducing a frothy mass of larger proportions than heretofore obtainable, in a very few seconds.

Another object of the invention is to provide a device of this'character which is sanitary, extremely simple in construction, du-

rable and one which can be manufactured at a very small cost.

In the accompanying drawing: Figure 1 is a side elevation of the device. Figure 2 is a sectional view on line 22 of Figure 1.

of the dasher. I

Figure 5 is a sectional view on line Ii 5 of Figure 1.

Figure 6 is a fragmentary view of another modified form of the invention.

Referring to the drawing, 1 designates the dasher which is formed from suitable sheet metal and includes a relatively flat central web 2 and integral wings 3 which are reverse- 1y curved and inclined outwardly from their lower edges to their upper edges, and in opposite directions, said wings being provided with a plurality of relatively small perforations 4. By reversely curving the wings itwill be observed upon reference to Figure 2 that they will be conca-vo-convex in cross section. The upper edge of the web 2 terminates in a a pair of spaced arms 5 and on the upper ends of which are formed tenons 5 adapted to be crimped into engagement wit-h the gear 6.

a Figure 4 is a side view of a modified form v The lower edge of the web 2 hasa lip 7 carried thereby and: in which is engaged the lower end of the shaft 8, the upperend of said shaft beingextended into a socket 9 formed'in the lower end of the head 10, there being a cross pin 11 carried by the head for maintaining the shaft in said socket. The head has ashaft 1,2 rotatably engaged transverselythereof and upon one end of which is fixed a comparatively large gear 13 which meshes with the gear 6 and since the gear 6 rotates upon the shaft 8 and is fixed to the arms 5, rotary movement will be impartedto the dasher'when the gear 13 is rotated through the medium of the knob 14 carried'by the gear 13. Y

Theupper end ofthe head 10 has a socket 15 formed therein and inwhich is fitted the extension 16 of the handle'loop 17. While I have illustrated and described specifically the V handle, it will be of course understood that the construction thereof may be varied if desired. 1 1 1 When the dasher is placed in a bowl or other suitable container and rotated it will be obvious that, sincethe wings are'curved reversely, the material being beaten will be trapped momentarily, due to the fact that the concavecl faces of the wings are presented against the material in the bowl, thus preventing a too rapid passage of the material across the wings. Due to the fact that the wings 3 arexinclined in opposite directions the inaterialwill, after the initial rotation of the dasher, be compelled to move upwardly and over the upper edge of the wings; Dur- '85 1 ing the initial operation of the dasher, the material being whipped, such as for instance, the white of an egg, will not flow over the upper edges of the wings, but will pass through the perforations 4, thus first aerat- ,2 ing the material and producing a froth which cannot pass through the perforations, and they centrifugal action will remove excessive moistue from the mass to produce a dry product.

lVhen the dasher is revolved rapidly an upward and outward draft or suction is pro duced near the longitudinal axis of rotation. Obviously, the material will not all immediately froth, and the thinner material will pass through the perforations and will be 10.0

precipitated against the side of the bowl and 7 will be drawn by the dasher to the bottom thereof where it will be again subjected to the action of the dasher. As the froth is produced by the agitation of the dasher it will naturally rise to the top of the material and owing to its lightness will remain, whereas the thinner material will be successively subjectedto the action of the dasher until thoroughly agitated to produce a mass which is exceedingly dry, stiff and light.

, Owing to thefact that the arms are spaced the upper end of the shaft 9 is accommodated in the space between said arms to properly aline the same.

In the modified form of the dasher' as shown in Figure 4, the dasher 18 includesupper and lowersets of wings 19, and since these wings function in the same manner as the wings of the preferred form a detailed description of its operation is not thought to be necessary. In the modified form of the invention shown in Figure 6, the shaft 8 has its lower 25 end rigidly secured to the dasherQO.

'Having .thus described the invention, I claim: 7 U i An egg beater comprising a dasher having an upstanding shank formed at its upper end vwith transversely spaced arms, the arms being twisted to dispose their upper ends at substantially right angles to the shank, tenons extending upwardly from the upper ends of said arms, a bearing projecting from the lower end of said dasher, a shaft extending longitudinally of said dasher with its lowerv end j ournaled in said bearing and its upper portion extending between the arms and projecting above the same, a gear fitting loosely 0 about said shaft and resting upon the arms, I the tenons being passed through the gear to rigidly connect the gear with the arms, a head connected with the upper end portion of said 7 shaft, and a drive gear rotatably mounted at one side of said head and meshing with the first gear. 7 p

In testimony whereof I afiix my signature.
