UNITED STATES PATENT rrrcno CONRAD BERST, OF KANSAS CITY, MISSOURI.

CHURN-DASHER,

SPECIFICATION forming part of Letters Patent No. 565,130, dated August 4, 1896.

Application filed May 22,1896. Serial No. 592 608. (No model.)

T0 all whom it may concern:

Be it known that I, CONRAD BERST, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Churn-Dasher, of which the following is a specification.

This invention relates to that class of dashers which in operation have a reciprocating movement imparted thereto; and the object of: the improvement is to provide a dasher which will offer a minimum amount of resistance to the substance being whipped or churned when returning to a normal orstarting position, thereby lessening the efiort required in the churning process and facilitating the return of the dasher to an initial position after it has advanced to the required point in its forward movement.

With these and other objects in view the invention consists, primarily, of movable beaters, which are adapted to move in a curved path and to assume a position immediately below and in vertical alinement with corresponding fixed beaters when the dasher is retnrning to a normal position or is in a quiescent state and not immersed in the cream, hatter, or other substance to be whipped or churned, and which movahle beaters will occupy a position in the plane of and side by side the said fixed beaters when the dasher is (lepressed or advancing on its forward stroke.

The improvement also consists of the novel features which hereinafter will he more particularly set forth and clai1ned, and which are illustrated in the accompanying drawin gs, in which Figure 1 is a perspective view of a dasher constructed in accordance with this invention, showing the movable beaters at their lower position. Fi g. 2 is a Sid e elevation thereof, showing the movable beaters at their highest position and in the plano of the fixed heaters. Fig. 3 is a transverse section of the dasher, showing the movable beater at its lowest position.

Referring by numerals to the drawings, in which similar characters denote correspond ing parts in all the figures, 1 indicates a stafi, 2 a cross-bar having oppositely-curved slots 3 near its ends and supporting the fixed beaters l and the movable beaters 5, and 6 the of the fixed beaters 4 and immediately below the contiguous fixed beaters, as shown most clearly in Fig. 2. The movable beaters 5 are mounted in the curved slots 3 and have circular enlargements 7 to come upon opposite sides of the cross-bar 2, so as to maintain the said movable beaters in working relation.

Vhcn the dasher is at rest and not im mersed in the cream, batter, or other substance to be churned, the movable beaters will occupy a vertical position immediaiely below the adjacent fixed beaters, and when the dasher is in working position and is moved forward the said movable beaters will occupy a position in the plano of the fixed beaters, as shown most clearly in Fig. 2. The movable beaters being of wood, are buoyant and on the initial movement of the forward stroke of the dasher the said movahle heaters will start upwardly in the curved slots 3 by reason of their buoyancy in the cream, batter, &c., being agitated, and this upward movement will be accelerated by the forward or downward movement of the dasher, as will be readily understood. When the dasher returns to a normal position the movable beaters Will descend to the lowest position of the curved slots 3 under the action of gravity, and the resistance of the substance exerted upon the said movable beaters, thereby lessening the effort required to elevate or return the dasher to its initial position.

The purpose of the breaker-bar 6 is to cause a lateral circulation of the cream on the for ward or down strolte of the dasher, and the lateral movement of the greater hulk of the cream will cause a corresponding movement of the fine jets passing hetween,the several beaters and will result in the cream being thrown violently again st the sides of the vessel containing the same, thereby breaking up the hutter globnles and securing a thorongh ICO agitation, which results in the churning or whipping in a eomparative1y short interval of time and in a thorough and effective ]l&llll.

In order to faci1itate the p1acing of the movable heaters within the eurved slots, the cross-bar is separated horizontaily and the parts are seeured together by screws 8 or other fastenings, by means of which the de sired result is attained.

What is olaimed is 1. A dasher comprising a support formed with ourved slots, a series of beaters attached to the said support and inoapable of independent movement, and movable beaters placed in the said curved slots and adapted to move automaticallytherein in the operation of the device and to occupy a position in the plane of the fixed beaters when the dasher is moved forward, and to occupy a position i1nn1ediate1y below and in verticai a1inement with the adjacent fixed beaters so as to offer no resistance to the return stroke of the dasher, substantiaily as specified.

2. The dasher constructed substantialiy as herein specified, the same. comprising a staff, a cross-bar having oppositeiy-disposed curved slots near its ends of quadrantal shape, fixed beaters supported between their ends at intervais in the length of the cross-bar, movab1e beaters arranged in the said curved slots, and having annu1ar enlargements to engage With the opposite sides of the cross-bar, said movab1e beaters occupying a position in the p1ane of the fixed beaters when the dasher is moving forward, and in vertical a1inen1ent With and mmediateiy below the adjaoent fixed beaters when the dasher is returning, and a breaker-bar arranged intermediate of the fixed beaters and at right ang1es to the said cross-bar, substantic 11y as set forth for the purpose described.

In testimony that l claim the foregoing as my own I have hereto aflixed my-signature in the presence of two witnesses.
