IINATOJO SYDNEY, OF BOSTON, MASSACHUSETTS.

BEATEB.

Application filed April 6,

This invention aims to provide an improved beater, particularly, though not exclusively, useful for beating eggs, cream, etc.

ln the drawings which illustrate a prell lerred embodiment of my invention li'ig. 1 is an elevation view of the beater; Fig. 2 is a sect-ion on the line 2-2 of Fig. l, being partly in elevation; n

lli 3 is a plan section on the line 3--3 le of Fig. 1 showing the rpropeller-like members; and

Fig. #l is a section on the line 4-4of Fig. E showing the assembly of the parts of the heater.

Referrin to the drawings, I have shown a beater which includes a trame part 1 formed trom a single iece of metal. The frame presents a hand e 2, a plurality of fingers 8 anially aligned with the handle and a pluralil@ ity of U-shaped slots 4 facing toward a finger 5 iorrned integral with the frame for supsorting a driving gear 6'. The beater also includes two propeller-like members or beaters 7 and 8 located one above lthe other ata ttl substantial distance below the frame.

ebeaters are formed in units, each oi which includes a propeller-like part, a shaft and a pinion gear, and both units arel assembled together prior to assembly with the lill traine. The beater 8 is secured to a collar 9 which in 'turn is secured to one end of a shaft le by a pin 16, as best illustrated in Fig. Q ,llt the other end of the shaft I have provided a pinion ear 11 which may be secured to the at shaft 1n any suitable manner. The propeller-lilre member 7 is secured directly to one end of the hollow shaft 13 surrounding the shaft 10 and at the other end of the shaft 18 l hare secured thereto a second pinion le ,gear 14, similar to the pinion 11. The second described unit may be-entirely assembled and placed over the shaft 10 before the pinion gear 11 issecured to the shaft 10, then when this pinion is secured in its proper position, la both units are assembled, although one may slide axially relativel to theother for purposes more fully hereinafter described.

Illhe whole beater is assembled as follows ll'irst the shafts 10 and 13 are placed into the lll-shaped slots 4 by sliding them between the ger 5 and the fingers 3, Fig. 4, then into the slots l so that the pinion 11 is located between the upper finger 3 and the handle 2. Wlille pinion 14 is placed between the two lower lingers 3 thereby preventing axial movement of the beater units relative to the lli 1925. Serial No. 20,944.

frame 1 or relative to each other. The driving gear 6 is then placed over the hub 15 formed integral with the linger 5 and a nut `16 is threaded onto the hub to hold the gear in position. The gear 6 meshes with the pin- Vions 11 and 14 and prevents movement of the shafts 10 and 13 out of the U-shaped slots until the nut 16 is removed. Thus all the units of the beater are held in assembled relation by a single n ut. The usual handle 17 is r provided on the gear 6 for rotation thereof. The rounded projection 19 is formed on the handle 2 so as to provide a smooth bearing point for the end of the shaft 10.

The propeller-like members 7 and 8 are pressed from sheet metal and have blades 18 twisted so as to direct: the medium, which is being mixed or whipped, upwardly in the case of the member 8 and downwardly as in the case of the member 7, thereby insuring a complete mixing of the medium. The blades. 18 are connected at their outer ends by a continuous rino' or band 18, Fig. 3, and from this band the blades extend toward the center or hub portion of the ropeller-like member tangential thereto andj at an angle pointing away from the direction lof rotation relative to a radial line from the center of the shaft. This is done so that the medium may be carried from the outer ends of the blades toward the center of the propellerlike members. These members are rotated in opposite directions and, therefore, the blades of each member slant inwardly in opposite directions as clearly indicated in Fig. 3.

In operation, the gear 6 is rotated, thereby turning the pinion gears at a relatively hig rate of speed and in opposite directions, thereby turning the shafts so that the propellerlike members 7 and Bare whirled at a relatively high rate of speed in opposite directions. When this action takes place with the rounded end of the shaft 10 resting on the bottom of a pan or dish, the substance therein will be drawn from the sides of the dish by both members 7 and 8. The blades 18 of the member 8 draw the substance from the edges of the dish toward the center thereof and at the same time direct it upwardly into the path of the member 7. At the same time the blades 18 ofthe member 7 are drawing the substance to be whipped from the edges of the dish t0- ward the center and downwardly into the path of the member 8, thereby insuring a complete intermixin g process, the whole substance being churned over and over.

The web 20 is formed in the handle 2 to prevent grasping the handle with the lingers in the opening 21, as it has been found that such a simple operation that the beater may be taken apart so that the units may be moved axially relative'to each other to provide a convenient space between the propeller-like members 7 and 8 whereb theblades may ver easily and quickly c eaned.

lg'hile I have shown and described a referred embodiment of my invention, it wi l be understood that changes involving omission, alteration, substitution of parts and even changes in the mode of operation may be effected without departing from the scope of my invention which is best defined in the appended claims.

Claims:

1. A beater including aframe, tyvo ropeller-like members" located relatively c ose together one above the other and means for rotating said propeller-like members in opposite directions, each 'of said members having a series of blades twisted so as to direct the medium which is being mixed into the path of the other member and said bladesv angled relative to radial, lines from the center of the member in a direction away from the direction of rotation so as to direct {,le medium toward the centers of said memrs. 2.' A beater including a one-piece frame, Vtwo propeller-like members located one above l the other and means for rotating said propel- 4 ler-like members in opposite directions, each of eac 3. A beater comprising, in combinations.

vframe partpresenting Aa lurality of fingers each having a U-shaped s ot generally axialof said members having a plurality of twisted blades angled relative to radial lines from the center of the member, said blades being thereby adapted to direct the medium which is being mixed from the outer periphery of said members toward the centers thereof and also u wardl-y anddownwardly member.
