SPECIFICATION forming part of Letters Patent No. 453,360. dated June 2, 1891.

Application filed March 11, 1891. Serial No. 384,608. (No model.)

, To all whom it may concern:

the county of Carroll and State of Indiana,

have invented certain new and useful Improvements in Churns; and I do declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specication.

This,invention relates to certain new and useful improvements inchurns; and it has for its object to improve upon the construction and to render more eflicient in operation this class of appliances.

The invention consists in the peculiar construction andY in the novel combination, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the accompanying drawings, and then specifically defined in the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this'speciication, like letters of reference indicating like parts throughout the several views, and in which drawings-- Figure 1 is a perspective view of a churn embodying my improvements, with parts broken away in order to better illustrate the construction and arrangement of the parts. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a vertical transverse section, and Fig. 4 is a bottom plan view, of the cover.

Reference .now being had to the details of the drawings by letter, A represents the body of the churn, which is preferably rectangular in form, and is supported by the strips B, which are secured to the side faces of the body A, and unite at their upper ends at a point above the upper face of the churn. The crankshaft C is journaled within suitable bearin s provided for the purpose within the upprsends of the strips B, and one of the ends o` l shaft being sleeved upon the cra-nk C2 of the crank-shaft C.

The inner faces of theside walls of the churn-body are each provided at their longitudinal centers with vertical strips E, and the dasher D is provided with transverse strips D2, which are secured to the upper face of the dasher, the ends of the strips extending beyond the outer edges of the dasher upon each side of the strips E, the said strips thus serving as a guide for the dasher in its verti cal movements, as will be readily understood. It will be noticed that the edges of the strips D2 are rounded upon the side adjacent to the guide-strips E, thus permitting the dasher to be given a slight rocking motion, as will presently be explained.

The cover G is made in two sections, as shown, and is provided ,with a longitudinal slot Gr for the passage of the dasher-stem D.

I-l is a strip or block, of either wood or metal, which is loosely sleeved upon the dasher-stem. This block is adapted to enter a space provided for its reception upon the inner face of the cover, and serve as a means for locking the cover in place. This locking mechanism will be best understood upon reference to Fig. 4 of the drawings, in which I have shown a bottom plan view of the cover. The strips J are secured to the under face of the cover along the longitudinal edges thereof, and attached to the said strips are blocks J', which extend for a short distance beyond the inner edges of the strips J, and when the cover is placed upon the churn the block I-I upon the churn-(flasher stem is raised and one of the ends of the block is placed within the space intervening between the cover and the blocks J. The section G2 of the cover is provided upon its under face with strips J 2, the ends of which extend for a short distance beyond the end of the section G2, and these projecting ends engage the under face of the opposite section of the cover, thus serving to lock the same in place, as will be readily understood. l

The operation of the churn is simple and `readily' understood. By turning the crank avertical reciprocating motion will be imparted to the dasher, and at the same time a slight rocking motion will be imparted thereto. The block H serves to effectually hold the cover in position, and as the block is allowed to move freely beneath the blocks J a free movement of the dasher-stem is permitted. The rods or strips L, which are pivoted at their upper ends upon pivots or bolts extendin g from the inner faces ot' the strips B, serve, when turned downward so as to canse their lower ends to bear upon the cover, as an additional means for holding the cover in place. These rods or strips may, however, be omitted, if desired.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, s

The combination, with a churn having a vcrtically-reciprocating dasher, of the twopart cover to the churn,having longitudinal opening G', the strips J, secured along the un-
