this specification, in which the same refer ence characters indicate the same parts and wherein:

Fig. 1, beater; F 1g. 2, is and Fig. 1.

is a'face view of my improved a side elevation-of the beater;

8, is a cross-section on line 33 rocatory bar slidably mounted within the frame. Beater or dasher arms 4 are pivotally carried by the lower end of bar 3, depending therefrom and tern'iinating in 'daslier portions proper 4 of substantially flattened volutoid form, the convolutions of one dasher portion being of different meas: urement to the corresponding convolutions of the other to allow the dashers to pass through one another. The beaters or dashers are preferably formed of wire and the pivotal connections between their upper ends and the bar 3 are made by loosely coiling the wire, at a short distance from the end around a headed pin 5 carried by the bar, the end portions of the wires being. bentat right angles to form short arms 4t extending transversely respectively in opposite directions and terminating at the sides of the frame between pairs of vertically disposed stops 6 upon the frame. The ends of the short arms 4* may be flattened or bent back upon themselves as shown for strengthening purposes. By the-described formation the beater wires constitute bell-crank levers with the pin 5 at'the angle, the longer arms pre- :eferring to thedrawings, 2 represents theframe of the beater and 3 a vertically rec1psenting the dasher portions proper 4 In operation theshorter arms 4", by, their alternate contact with their respective upper and lower stops 6, during the reciprocation of the bar. 3, translate such reciprocatory movement into an oscillatory movement for the dasher portions proper. The distance,

between the upper and lower stops 6 permits a limited vertical movement of the heaters with the bar, and such Vertical movement with the oscillatory movement mentioned re-- .sults in each dasher portion proper having an approximate eiiiptical oscillatory movement in a vertical plane.

The reciprocation of by means of a camplate 7 pivotally mounted upon the frame 2 and formed to presenta series of exterior cam faces 8sin the pathof movement of which a pin 9 carried by the upper end of the bar-projects, eachcam face graduating tangentially outward froin the camplate proper to straight edgeportion'8 at an angle thereto which provides an abrupt the bar 3 and coin sequent operat on of the dashers is secured.

drop back to the camplate. Rotationof the 'camplate by a handle 9 causesthe graduated faces through pin. 9 to movethe bar. upwardly and the straightedge portions 8 permit it to drop, thus reciprocating the bar.

To avoid reliance u on ravit onl for.

the downward movement of the bar I pref erablyprovide a second pin 10 onthe bar.

near its lower end and position the camplate between the pins, the cam faces being arranged 1n staggered relation, so that immediately subsequent to the arrival at and, passing-0f the straight edge 8*? of a cam surfacev beyond one pin during movement of the bar in one direction the graduated portion Ofan opposite cam face engages the other, pin and forces the barin the opposite direction, 1

As shown I prefer to, make the cam mecheanism in plate form and by bending over. the edges of the-plate presenting the cam' faces to form antifriction treads 11 prefer-.

ably curved in cross section, which, with the pins?) and 10 carrying antifrict'ionq rollers 12, means a much more satisfactory operation of .the reciprocating bar; and

through it the dashers.

It is also preferable that the straight edge a isdevoid of parts such as gears and pinions which are subject tomuch wear in the necessanily speedy operation. of heaters of this character.

Tosimplify and cheapen construction; the frame 2 is, as shown, formed from: a single length. of wire, of a material and. gauge to be easily manipulated and yet provide the requisite rigidity, first bent centrally of its len'gtlrto form the handle portion 2a of oval form, then to provide parallel spaced verticalzside portions 2 upon which the operating mechanism is carried, and each side, portion is: then bent obliquely outward to a point, sufficiently beyond the dashcrs where it is turned. graudal'ly to a: right angled horizontalubase section 2 extending toward the opposite side to be again: bent so ass-to; extend;

liquely upward and be connected as at 2 to the opposite side portion at its point of divergence from the, vertical.

It willbeapparent that by such simple divergence of the lower portions of the frame wire: and bending. themto present the horizontal base sections 2 the beater is provided with. abase by whichit' can of itself standi upright.

To provide a. substantial pivotal and steadying mounting for the camplate 7 the side portions of the frame are; bowed out atc13- and have mounted thereon a bearing plate 14:, secured in-place by lugs 15 formed on the plate and bent to clasp suclrside portions, the bearing plate having a central opening to accommodate a retaining pin 16 and the edge of such opening being flanged outwardly to form a pivotal boss 17 upon which a similar pivotal boss 18, formed: by fiangingthe edge of a central opening in the camplate, rotatabl'y fits, the camplate being held in place by the head 19 of the retaining pin. 7

Plate 14 provides the guides for the reciprocating bar 3, which is of flat strip form with its ends bent back upon itself at 3' to lend rigiditythereto and strengthen it at the points at which the pins 9 and 10 are mounted,the plate presenting lugs 20, bent to loosely overlap the bar, and a flange 21, with a vertical slot 22 to snugly accommo date it, the slot being open to facilitate assembly.

The side portions 2 of the frame are joined and braced by a brace plate 23 located above and adjacent the point of their divergence from the vertical, such brace plate spanning the space between the frame portions and having its side margins flanged to flank the sides, the lower portions 23 of the flanges being bent around the frame por tions to fasten the brace thereto, while the upper portions 23 present vertical slots 24 through which the short arms l of the dashers protrude, the ends of the slots constituting the stops 6 to be engaged by such arms as before mentioned. I The bottom margin 23 of the plate 23 is bent horizontally and formed. with slots 23 to receive and assist in maintaining in the required relative positionwthe oscillating dasher arms the slots being open at one end-to facilitate the entry of the beater arms during assembly, and the plate being also recessed at 23 to accommodate the adjacent end of pin 5 carried by the reciprocating bar 3.
