BMPROVEM ENT EN CHURNS.

To all whom it may concern:

Be it known that I, D. A'. FIsKE, of Delavan, in the county ot' Walworth and State of Tisconsin, have invented a new and Improved Ghurn; and l do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which` Figure l is a Vertical central section of my invention, taken in the line x x, Fig. 2; Fig. 2, a detached under View of the cover or lid of the same; Fig. 3, a detached plan or top view of the dash. Figui is an edge view of one of the pivoted win gs of the dasher hereinafter described, and illustrates also, in red lines, the position of the other pivoted wing. Fig. 5 is an edge view ot" the entire flasher in an inverted position, looking endwise at t he wings, and representing them in an expanded position.

Similar letters of reference indicate like parts.

This invention relates to a new andim proved churn of that class which are provided with a reciprocating dash 5 and it consists in a novel construction'of the dash, whereby the same may befoperated with the greatest facility and the cream agitated so as to cause butter to be produced within a short period of time.

The invention also consists in the application of a chamber' to the vlid or coverof the churn to prevent the cream from escaping` through the lid or cover around the dash-rod during the operation oi' churning.

A represents the body ot' the churn or cream receptacle, which may be of conical, cylindrical, or other ferm. I prefer however to have the cream-receptacle of cylindical form internally, equal in diameter throughout. The exterior may be made taper or of conical form, if desired.

B represents the dash, and G the dash-rod. The latter is of iiat form,and the dash is constructed as follows: The lower end of the dashrod is framed into a cross-bar, D, and to each end of the latter there is secured a curved bar, E E, both being portions of the same circle, and each forming rather more than a quarter of a circle, as will be seen by referring to Fie. 3.

F F represent two flaps, which may be described as being semicircular in form, with parallel slots a made in them extending from the curved edge toward the straight edge. (See Figs. l and 3.) To the straight edges of these iiaps cleats b are attached at one side of the same, and these cleats extend sufliciently beyond the ilaps to admit ot'jcurnals c being formed on them, said journals being fitted in the curved bars E E and allowed to turn freely therein.

The iaps F are placed at opposite sides of the cross-bar D, and the journals c of each cleat b are not in line with each other, as will be seen by referring to Fig. 3, and this causes the laps F, when closed against the bars E, to have a slightly inclined position.

The journals ot the cleat b of one tlap have a reverse position to those of the other cleat, and hence when the two flaps are closed against the bars E E the former will be inclined in reverse directions, and will give or impart to the cream as the dasher descends a rotary motion. In raising the dasher the iiaps drop and pass readily up through the cream, the iiaps instantly closing as the dash is pressed downward.

By this arrangement a very simple and efficient churn-dash is obtained, one which may be operated with facility or with but a moderate expenditure of power. It differs from other dashers of a similar class by having its iaps hung so that they will have an inclined position when the dash is forced down, and thereby impart a rotary motion to the cream. This is an important feature, as it greatly adds to the efciency of the dash, causing it to give a greater degree of agitation to the cream and expediting the production of the butter.

The lid or cover G of the churn is provided with an oblong opening, c, for the dash-rod C to work through, and to the under side of the lid or cover there is secured a chamber, H, through which the dash-rod G also passes. This chamber may be of any suitable shape or form, and it serves to prevent the cream from escaping or splashing out through the opening in the lid or cover, as the chamber catches and retains it, and the inner sides of the chamber are inclined, so that the cream may readily pass therefrom down into the reeeptaele A. The dash may be operated by a oi' the other, substantially as and for the pnr lever, A', or directly by hand. pose set forth. i'
