set themilk into a violent motion when rotated. I

Another object is to iprovide'a churn em-, ploying a glass containing vessel that will permit the operator to observe readily the progress of the churning operation: and which will adapt the churn to be readily cleaned adding to its desirability from the viewpoint of sanitation. I

A still further object of theinvention is to provide a device oft-he character lde; scribed that will be strong, durable, simple and efficient and comparatively inexpensive to produce, also one in which the several parts will not be likely to get out of working order.

lVith the above and other objects in view, the invention has relation to certain novel features of the construction and operation, an example of which is described in the following specification and illustrated in the accompanying drawing, wherein: p

Figure 1 is a view showing my churn in front elevation. Fig. 2 is a detail perspective view showing one of the dashers. Fig. is a sectional end view of the other dasher taken upon the line XX of Fig. 1. Fig. at is a detail sectional view taken upon the line YY of Fig. 1.

Referring now more particularly to the drawing, wherein like reference characters designate similar parts in all the figures, the numeral 1 denotes a globular glass vessel formed with a large opening in its top encircled by a flange 1*. Upon this flange is fitted a cover 2 upon which is centrally surmounted a cast standard 1 rigidly secured to said cover by any suitable means. The upper extremity of the standard 4 is of $81111-Cl101ll5t1 form as indicated at a", a horizontal bar 4* being mounted in a diametral relation to said semicircular portion, the parts't and 4 formlng a handle. A horizontal sleeve 5 projecting integrally outward :from the standard 1 is spaced some distance above the cover 2 of theivessel 1 and serves as a bearing for a shaft 6 adapted to be manually subjected to rotation by a crank-arm mounted upon the outer end of said shaft. Upon the "other extremity of said shaft there is mounted fast a bevel gear 8. Atits top and bottom, said gear respectively engages two bevelpinions 10 and 11, which are" respectively fast and loose upon a vertical shaft 9 journaled at its upper end in the member 4 and passing 5 centrally through the base 9 of the stand ard 4t and through the cover 2 into the vessel 1 extending. to the bottom portion thereof. The pinion 11 is fast upon asleeve 12 which sleeve projects slightly into the vessel l and pro ectsa suflicient distance above the correlated p nion to serve as a truss bearing for the pinion 10 preventing any downward displacement of the same and of the shaft 9.011 which said pinion is fast.

The pinion 11 is itself restricted from.

downward displacement due to the fact that it rests rotatably upon the base 9. i

Within the vessel 1, there is clamped to the lower end of the sleeve 12 a clamping bar 13 from the extremities of which a pair of vertical rods 14-. extend rigidly downward terminating substantiallyin the central portion of the vessel 1. The lower extremities of said rods carry a dasher member having an elongated centralbody 15 of square crosssection, said body beingpreferably disposed with its diagonally opposite longitudinal edges respectively alined horizontally and vertically. Upon each of the end faces of the body 15 a vertical paddle 16 is mounted fast, equidistant from the lateral edges of the body. Upon the extremities of said body,

15 a pair of inclined plates 17 are respectively secured, said plates being contiguous respectively with the two under faces of said body and having their extremities projecting equidistantly beyond the body. the lower extremity of the shaft 9 there is mounted a second dasher similar to that comprised by the parts 15, 16 and 17 except for the fact that the plates 17 are inthis case secured to the two top surfaces of the Upon member 15 rather than to the under surfaces thereof.

The bottom of the vessel 1 is fitted with a drain valve 18 through which the liquid contents of the vessel may be conveniently withdrawn.

hen the crank 7 is turned, it is apparent from the above description that the shaft 9 and the sleeve 12 will be subjected to rotation in opposite directions so that the two dashers each comprising parts 15,16 and 17 will also be oppositely rotated. The con-- struction of the two dashers is such that their simultaneous rotation in opposite directions will produce a very violent agitation of the milk which is being churned, one portion thereof being whirled in one direction of rotation by the paddles 16 of the upper dasher and another portion being oppositely whirled by the paddles 16 of the lower dasher. That portion of the contents of the vessel lying between the two 'dashers will be very violently agitated due to a pressure acting downwardly from the upper paddles 17 and a pressure acting upwardly from the lower paddles 17. The upper and lower faces of the body 15 will also force a portion of the milk upwardly and clownwardly simultaneously whirling the same.

The use of the two separate dashers oppositely rotating as described gives to my churn an efliciency that makes it possible to copiel of thia patent may be obtained for perform the operation of churning in a comparatively short time.

The exertion of very little manual effort is required to maintain the above described churn in operation.

The invention is presented as including all such modifications and changes as properly come within the scope of the following claims.

IVhat I claim is:

1. In a churn dasher, an elongated horizontal member having a rectangular crosssection, vertical flat blades, one at each end of the member, and a pair of inclined plates secured to the ends of the member adjacent the blades.

2. In a churn dasher, an elongated horizontal member having a rectangular crosssection, vertical fiat blades, one at each end of the member and a pair of inclined plates secured to the ends of the member adjacent the blades, the plate at one end being inclined opposite to the plate at the other end.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
