SPECIFICATION forming part of Letters Patent No. 297,109, dated April 22, 1884.

Application filed May 1G, 1883. (No model.)

To all whom it may concern:

Be it known that I, JOHN II. BURCK, of North Hoosick, in the county of Rensselaer and State of New York, have invented.A certain new and. useful Improvements `in Churns, of

which the following is a specification.

In the accompanying drawings, which form part of this specification, and to which Vreference is made herein, Figure 1 is a perspective ro View of an oscillating churn; Fig. 2, a longitudinal section of the same, and Fig. 3 a detached detail, showing the construction of the device for securing the cover in place.

As shown in the drawings, A is the body or cream-holding receptacle of the churn. The said body constitutes the cream chamber, which consists of two wings, a and a', arranged at an angle to each other, which angle I preferably make a little over ninety degrees, so as 2o toleave an unobstructed passage between them.

i At the apex of the angle the body A is leveled off to form the opening` a?, through which access is obtained to the interior of the churn.

. Spiders B are attached, to the opposite sides of the body A, near the point of intersection of the center lines of the wings a and a. Each of said spiders has projecting therefrom a trunnion, b. the same line and form the center upon which 3o the body A is oscillated.

The framework C is provided with uprights c, and in the upper ends of the latter bearings are formed for receiving the trunnions b. The

said frame-work constitutes a support for the body A during the operation of churning.

The crank D is secured to the outer end of Roth of said trunnions range on one of the trunnions b, for the purpose'of irnparting the required oscillatory motion to the body A.

The bonnet or cover E closesover the open- 4o ing a2 in the body A, and is provided with a packing, e, which is fixed beneath the under side of its flange for the purpose of forming a tight joint with the body A. A transverse shaft, F, is fixed on the upper side of said bonnet, and has the hooks j' secured to its opposite ends. Said hooks are adapted to engage with eccentrics G, which are pivoted to the sides of the body A and are provided with operating-levers g. When the hooks f are en- 5o gaged on the eccentrics G, the latter can be turned on their pivotal centers by means of the levers g, and by so doing the hooksf will be drawn downward to clamp the bonnet E closelyY and securely over the opening a2.

When preferred, a lever extending from one or both sides of one of the trunnions b may be substituted for the crank D for the purpose of imparting an oscillatory motion to the churn.

I claim as my inventionc 6o In a churn, the combination, with acreaniholding receptacle provided with eccentrics G, as herein described, of the cover E, provided with a shaft, F, having pendent hooks f, adapted to engage with the eccentrics G and secure said cover in place, as herein speciied. t
