v CULINARY BEATER.

Specification of Letters Patent. Patented Dec, 31, 1918,

Application filed July 18, 1917. Serial No. 181,399.

. an in drawin is a s ecification like v Fig. 2, of Fig. 1.

characters on the drawing representing like parts. I

This invention relates to culinary beaters and mixers and the like, more particularly it relates to hand operated heaters for beating eggs, frosting. confectioneriesand the like. In order to illustrate my invention I have 7 shown in the accompanying drawing one embodiment thereof; wherein; Figure 1, is an elevation of a beater embodying my invention." I

is a horizontal section on line 2- 2 Fig. 3, is a horizontal section On line 3-3 of Fig. 1. 7

And Fig. 4, is a modification hereinafter described. The terms employed herein are used in the generic and descriptive sense and therefore are not intended primarily as terms of limitation.

In the drawing 20 represents a base of any suitable or preferred type or form best adapted for a contact member to engage the interior bottom of any desired vessel or container utilized to hold the article to be mixed or beaten.

Pivots 21 and 22 are located at diametrically opposite positions upon the said base 20 and swiveled thereon are the beater members 23 and 24 respectively. I

The said beater members 23 and 24 are preferably circular or circumferential in form both of the same size or of the same diameter and with their axesat all times in a plane transverse one to the other whether in rotation or stationary bythe means provided hereinafter. said beater members in any suitable manner at the top thereof are relatively thin, fiat, spiral or twisted members 27 and 28 respectively each adapted to extend flatwise through the slots 29 and 30 through the reciprocatory bar 32 secured to or integral with the reciprocating rod 33 at right angles thereto.

The upper ends of said members 27 and 28 Integral or secured to.

are pivoted or rotatable at 35 and 36 respectively in holes in the guide bar or brace 38 which has a centrally located slot 39 through which the reciprocating rod-33 is vertically slidable. Therefore, while the reciprocating bar 32 is slidable axially of the members 27 and 28 the bar or brace 38 is stationary thereto but allows of pivotal ,movement of the said members 27 and 28.

The reciprocating rod 33. is provided at the top thereof with a suitable handle ll and interposed between which and the bar or brace 38 is a long spiral spring 42 encircling the said reciprocating rod. Interposed between the bars 32 and 38 is asimilar but shorter spiral spring or buffer spring 43 normally adapted to imit the; upward movement of the handle 41' and the reciprocating rod 33 under the action of the spring 42. T

Other suitable means than the bar 32 may be employed slidable longitudinally upon the members 27 and 28 to rotate them. For

example, referring to Fig. 4, I illustrate a handle or grip 48 provided with a couple of channels orcounterbore's each provided with a spring 50 to engage the stationary Washers .swiveled on the ends of the members 27 and 28 normally to force them out of said counterbore. Suitable slotted ferrules or' the like are provided toembrace the said members 27 and 28 tocau'se them to rotate in the same manner asdoes the bar 32.

Theapplication and'operation of my in vention is as follows:

The article or'substanceto be mixed or beaten is placed as usual in the aforesaid container or vessel. The operator then grasps either the handle 41 or the handle 48 as the case may be-and brings the base 20 into contact with the interior bottom in the said vessel. Then by a rapid down movementof the handle 41 the reciprocating rod 33 is moved downward carrying with it the reciprocatory bar 32 causing the said members 27 and 28 to move through the slots 29 and 30 and as the said members 27 and 28 are spiral or twisted they will rotate. The direction of the spiral of the member 27 is opposite that of member 28 so that the beater portions 23 and 24 will rotate in opposite directions during the said downward movement of the bar 32; Thus the beater 23 is adapted normally to pass within the circumferential or peripheral plane of the beater 24.- when the latter is entering and leaving the plane transverse to the former.-

As continued rotationis had the relativevpor sitions of the said beaters 23 and 24 Will change constantly but the axes thereof Will always be transverse one to the other.

Eventually or during the next half revolution the beater 24 Will pass Within the circumferential or perpendicular plane of the beater 28. In this manner each beater Will alternately pass the other beater as the axis of one or the other crosses the opposite one in the plane'of rotation- -When'the extreme downward movement of the handle 41 is each beater will rotate in its own direction for two or three turns dependent upon the length andpitch of the spiral members '27 and -28 after Which they will then reverse their direction each assuming a difierent direction of rotation. to that previously had. By placing the heaters 23"and 24 close to gether and prov dmg'each .With a spiral in the reverse direction. to rotate them in rev verse directions the edges thereof Willhave pass Within the outlines of the opposite beater and'a-lso each rotate in the opposite direction," and quicker-land more complete mixing orbeating 1S obtained-than W-ith'de' vices heretofore known. 1

(The construction of the heater is relatively simple and every part is open to inspection and cleansing. With regard'to'the modification illustrated by Fig. 4, the operav tionthereof is similar to thatshown by Fig.

1. That is the rapid reciprocation of the member: 48 Which'causes the heaters 23 and 24 to 'rotate'in the same manner until the handle comes to rest, after which the springs 50 Will return the said handle to its original 1 position'again causing said heaters to rotate but in the reverse direction.

I have described herein one embodiment or mytinventi o'n, but it is to be understood that'the latter is not essentially limited to. the
