CHURN.

Application filed May 29, 1922. Serial No. 564,507.

T 0 all whom it may concern Be it known that we,'Dnn Aynns and HAL DEE F ossnrr, citizens of the United States, and residents of Mount Vernon, in the county' of Lawrence, in the State of Missouri, have invented certain new and useful Improvements in Churns, of which the following is a specification.

This invention relates to agitators or churns especially adapted for use as a butter churn, a cream whipper, a pastry mixer and the like.

Briefly stated an important object of this invention is to provide novel means whereby the agitators may be applied to receptacles of various heights.

Also the invention forming the subject matter of this application aims to provide an agitator having simple means whereby the same may be applied to receptacles of various widths.

Also the invention aims to provide an agitator which is smooth in operation, of highly simplified construction and cheap to manufacture.

Other objects and advantages of the in vention will be apparent during'the course of the following description.

In the accompanying drawing, forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a perspective of the improved agitator for the churn.

Figure 2 is a vertical sectional view through the improved agitator.

Figure 3 is a detail horizontal sectional view illustrating a guide embodied in the invention.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 generally designates a receptacle of any desired shape or size and which as illustrated in Figure 2 isprovided with a closure 6 to which the construction forming the subject matter of this application is applied.

The churn comprises a triangular frame having a pair of inclined standards 8, said standards having their lower ends formed with base members or feet 10 secured to the lid or closure by means of fastening devices 12. It will be observed that the height of the frame may be varied to some extent by moving the attaching portions 10 away from or toward each other. By reason of this construction the frame may be applied to receptacles of various sizes.

The upper portions of the standards 8 are secured to opposite sides of a bearing member or head block 14:, the said head being formed from a length of sheet metal or. other suitable material bent between its ends to provide the opening for the reception of.

the crankand the ends of the piece of metal are arranged flatly in contact with each other and between the upper portions of the standards 8. Suitable fastening devices,

such as bolts 15 may be'extended through fined between the standards and the saidguide strip 17 may be provided with openings for the reception of the fastening devices 15 whereby the guide strip issecurely held in position. The end portions of the guide strip 17 are arranged in U-shaped formation and cooperate with one side of thebearing member 14in defining an opening for the reception of dasher members 18.

The dasher members 18 are square in cross section and have their lower ends formed with a itating devices 20 of any desired type. he agitator rods 18 are slidable through'the closure 6 and are guided thereby and by the U-shaped guide members 17 so that the dasher rods cannot get out of position. A shaft 23 is rotatably extended through the bearing member 14: and is provided with oppositely directed cranks connected to bearing members 25.

In carrying out the invention the bearing members 25 of which there are two are formed from single lengths of metal bent intermediate their ends to provide openings for thereception of the cranks of the shaft 23 and the end portions of the several lengths of metal are arranged flatly in contact with each other and are formed with openings for the reception of the attaching portions 26 of pitm'an rods 27. It will be observed that the return bends which define the attaching hooks 26 dispose the attaching hooks flatly in contact with the adjacent sides of the bearing members and thereby hold the end portions of the strips, of metal against spreading. The connection thus provided between the crank shaft and the pitman rods 27' absolutely prevents binding and provides a smooth connection between the parts.

Figure 1 illustrates that the lower portions of the pitman rods are extended laterally to provide dasher receivingmembers 30 which are received within transverse grooves 31 in the dasher rods 18. Suitable plates 33 are applied to the rods 18 and extend over the attaching portions 30 for connecting the same to the dasher rods. It will be observed that there are a plurality of transverse grooves 81 in each dasher rod so that the connection between each rod 27 and the associated dasher rod may be varied as the occasion requires. That is to say the effective length oi the dasher rod may be Varied for use in connection with shallow and deep receptacles.

Summarizing this invention, it will be observed that the bearing member let which is disposed between the upper portions or the standards 8 not only serve as support ing means for the crank shaft but also at one side of the guides for the dasher rods 18. The bearing member i l also serves as a spacin element for the upper ends of the standarc s 8.

In operation the handle 38 of the crank shaft is rotated for moving the pitmen mem bers 27 vertically. The movement thus imparted to the pitman rods 27 causes the dasher rods to move vertically for rapidly agitating the contents of the receptacle.

The particular connection between the pitman rods 27 and the crank shaft provides an extremely smooth connection between the several parts so that no binding will occur and consequently the churn may be operated with a minimum of efliort on the part of the operator.

Having thus described the invention, what we claim is A churn comprising a receptacle, a closure carried thereby, a frame mounted on said closure and inclusive of a pair of converging standards, a bearing member formed from a single length of metal bent intermediate its ends to provide a transverse bearing opening and a pair of attachin plates, said attaching plates being arranged flatly in contact with each other and being confined between the upper portions of said standards, a crank shaft extending through said transverse bearing opening and having oppositely arranged cranks, a guide strip having its intermediate portion conlined between the upper portions of said standards and having its end portions arranged in U-shaped formation and co-opcrating with said bearing member in defining a pair of vertical guide openings, dasher rods movable through said vertical guide openings and through said closure and guided thereby, pitman rods connected to said dasher rods and said crank shaft, and fastening devices extending through the up per portions of said converging standards, the intermediate portions of said guide strip and the attaching plates of said first named bearing member.
