To ctZZ ZL'h-OYJL it may concern.-

Be it known that I, NEPHI PACKARD, of Springviile, in the county of Utah and Territory of Utah. have invented certain new and useful Improvements in Churns, of which the following is a specification, reference being had to the accompanying drawings.

The object of my invention is the production of a rotary churn adapted by reason of its novel construction to expedite the operation of churning and to facilitate the removal of the product.

In the accompanying drawings, Figure .l is an elevation of my churn, illustrating the means of securing the cover. Fig. II is a similar view showing the side of the churnbody broken away. Fig. III is a top plan view of my churn. IV is a detail view of the dasher, and Fig. V is a perspective of the lock-spring and cam-lever.

Referring to the figures on the drawings, 1 indicates the churn-body, which is preferably of cylindrical form, rcvolubly mounted in suitable bearings 2 by means of trunnions 3 projecting from dianietrically-opposite sides of the churn-body and secured thereto by means of trunnion-plates i, as illustrated.

5 indicates a crank secured to the extremity of one of the trunnions for imparting rotary motion to the churn-body.

(3 indicates a cover provided with an annular recess 7 and a resilient band 8 secured therein adapted to rest upon a similar band 9 upon the upper edge of the churn-body. \Vhen the cover is in place, these bands are adapted to afford a close connection between the cover and the receptacle, and are preferably of soft rubber or similar material. The cover is provided, preferably, with a somewhat convex upper surface, and is provided at its center with a metallic plate 11 and with radial plates 12 extendin g from the plate 1 l to the periphery of the cover.

it indicates a locking-spring tapering from its middle toward its ends and provided with a vertical longitudinal slot in which is piw oted a cam-lever 15, provided with a handle 16 and cam 17. hen it is desired to close the churn-body the cover is placed in posi tion and the lock-bar 18 is placed thereon, its extremities extending through apertures 19 in diametricallyppposite cars 20 secured to the churn-body at its top, the cam-lever in this position being thrown back to the position indicated by dotted lines in Fig. 1. It will be observed that the operator, by grasping the lever and throwing it to the reverse position, will cause the cam to force the cover securely against the top of the churn-body, the spring-bar yielding sufficiently to allow the nose i l of the cam to pass beyond the line of the pivot, when, as is evident, the resiliency of the bar will lock the cam-lever and firmly secure the cover.

22 indicates a double dasher, consisting of two racks 23, composed of vertical parallel strips 24 and transverse bars 25, the transverse bars of the two racks being placed alternately, the transverse bars of one rack being in the same horizontal plane as the space of the other rack.

20 indicates lugs upon the lower ends of the vertical rack-bars, adapted to fit in the recesses 27 in the bottom of the body.

2% indicates tie-bars pivotally secured to the upper extremities of the vertical rackbars of one rack and provided at their opposite ends with tongues 29, adapted to fit in grooves 30 in the upper extremities of the rack-bars of the other rack. The shoulders of the tie-bars are somewhat inclined, as illus- 'trated, to force the upper ends of the racks apart and securely wedge them within the churlrbody.

It is evident that the racks may be easily placed within the body, but that when the tie-bars have forced them apart and wedged them securely against the curvilineal sides of the receptacle, they are securely fastened in place, the cover bearing against the tiebars and preventing their casual displacement. It is quite apparent, however, that as soon as the cover is removed the tie-bars may be lifted, allowing the racks to approach the center of the receptacle and to be easily removed.

' I do notdesire to limit myself to the details of construction herein shown and described, but reserve to myself the right to change, vary, and modify the same within the scope of my invention.

I clainr 1. The combination with a cylindrical body part, of a plurality of racks therein, tie bars pivotally secured to one rack and having incline shoulders at their opposite extremities adapted to engage the opposite rack and Wedge said racks against the cylindrical body part, and a cover adapted to force the tie bars in place, substantially as specified.

2. In a churn, the combination with a cylindrical churn body, of a plurality of racks therein consisting of vertical rack bars and transverse rack bars located alternately, and

tie barshinged to the upper extremities of the vertical bars of one rack and provided with tongues adapted to engage grooves in the upper extremities of the vertical bars of the other rack, said tie bars being provided with inclined shoulders adapted to bear against the vertical bars of one rack to "Wedge the racks securely Within the churn body, substantially as specified.

3. The combination Withacylindrical body part, of a plurality of racks therein, tie bars pivotally secured to one rack and adapted to engage the opposite rack and Wedge said racks against the cylindrical body part, a cover adapted to force the tie bars in place,

a spring bar above the cover secured at its opposite ends to the churn body, and a pivoted cam lever directly pivoted to the spring bar and engaging the cover to force the same against the tie bars, substantially as specified.

4. The combination with a cylindrical body part, of a plurality of racks therein, tie bars pivotally secured to one rack and having inclined shoulders at their opposite extremities adapted to engage, the opposite rack and Wedgesaid racks against the cylindrical bod y part, a cover adapted to force the tie bars in
