IMPROVEMENT IN ROTARV CHURNS.

Specification forming part of Letters Patent No. [$3,450. dated July 24, 1877 application filed March 24, 1877.

To all whom it may concern Be it known that I, WILLIAM KNAGGs, of Richview, in the county of Peel, Province of Ontario, and Dominion of Canada, have invented a new and useful Improvement in Ghurn- Dashers, of which the following is a specification:

Figure 1 is a cross-section of my improved churn-dasher, taken through the line .fr Fig. 2. Fig. 2 is a side view of the dasher. Fig. 3 is a detail view of the dasher-rod fastener.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved churn-dasher which shall be so constructed as to bring the butter very quickly, and gather it quickly and thoroughly.

The invention consists in the dasher formed by the combination of the two end bars, thetwo pairs of concaved bars, the stop-arms, and the two pairs of pivoted bars with each other and with the dasherfrod; and in the combination of the bearing, the plate, the pivoted latch, and the catch, with the enlarged and grooved upper part of the dasherrod, as hereinafter fully described.

lA A are the end bars of the dasher, the rear corners of the ends ot' which are rounded ofi', as shown in Fig. l.

To the forward parts of the ends ot' the bars A are attached the ends of two bars, B, made in the form of longitudinal sections of a hollow cylinder, and which are placed with their inner edges at a little distance from each other.

To the end bars A, between the adjacent edges of the bars B, are attached the forward ends of the arms O, the rear ends of which are forked, and provided with projections to serve as stops to the bars D. The bars D are pivoted at the inner corners of their ends to the l arms C, at or near the rear edges ot' the ends ofthe bars A. The bars D are made of such a Width that, when turned forward, their outer edges may rest against the rear sides of the inner edges of the bars B, and close the opening between said bars B. When the bars D are turned back they rest against the projection of the stop-arms C, and are heldin an inclined position, as shown in Fig. l.

The dasher-rod E is madesquare, passes through square holes in the centers of the crossbars A, and its end revolves in a step or socket attached to the bottom of the churnbody.

The other end of the rod E is enlarged, passes through a bearing, F, inserted in a hole in the top of the churn-body, and lattached to orformed upon a small plate, Gr, secured to the said top.

The rod E just above the plate Gr has a ringgroove formed in it to receive the notched edge of the latch H, pivoted at one end to the plate G. The other end of the latch H shuts beneath a keeper, I, also attached to the said plate G. l

`The upper end of the rod E is squared 0E to receive the eye of the crank by which the dasher is operated.

By this construction, when the dasher is turned forward the milk is drawn inwardby the bars B, is forced through the opening' between their inner edges, and strikes against the inclined bars D, by'which itis divided and thrown in opposite directions. When the dasher is turned backward, the rear sides of the bars B D act as paddles or ladles for gathering the butter. Y

Having thus described my invention, I claim as new and desire t0 secure by Letters Patentl. The dasher formed by the combination of the two bars A, the two pairs of concaved bars B, the stop-arms'G, and the two pairs of pivoted bars D with each other and with the dasher-rod E, substantially as herein shown and described.

2. The combination of the bearing F, the plate G, the pivoted latch H, and the catch I, with the enlarged and grooved upper part ot' the dasher rod E, substantially as herein shown and described.
