SPECIFICATION forming part of Letters Patent No. 525,980, dated September 11, 1894.

Application filed March 3, 1894. Serial No. 503,212. (No model.)

To all whom it may concern:

Beit known thatwe, STEPHEN D. FRY and JOHN R. HAMILTON, citizens of the United States, residing at Attica, in the county of Fountain and State of Indiana, have invented certain new and useful Improvements in Ohurns, of which the following is a specification, reference being had therein to the accolnpan ying drawings.

This invention relates to a new and improved churn, and it has for its objects to provide a simple and eflicient means for producing the butter from the cream; for collecting the butter when formed; and for raising it out of the churn when collected.

The invention consists of the novel combination and arrangement of parts hereinafter described and particularly set forth in the claims appended.

In the drawings:-Figure lis a vertical sectional view of the churn. Fig. 2 is a side elevation of the churn dasher; and Fig. 3 is a plan view thereof. l

Referring to the various parts by numerals, 1 designates the churn-body, which is cylindrical, and is formed of suitable metal such as tin or other sheet metal. 2 is the cover therefor, which is dished or concave on its upper surface and is provided at its center with a short dependingtube 3 through which the vertical dasher-shaft 4 passes. Theupper end of this dasher-shaft extends a suitable distance above the cover 4 to provide a suitable hand-hold, and at its lower end it carries the dasher-head 5. This dasher-head consists of ahorizontal disk 6 of sheet metal which is formed with a suitable number of radial cuts that extend from its outer edge inwardly a suitable distance, said cuts terminating short of the center of said disk. The metal on one side of each of these radial cuts is bent upwardly, while the metal on the other side of each of said cuts is bent downwardly, thus forming a series ofalternating wings 7. As is manifest, as many of these cuts as are desired may be formed in said disk.

At the inner ends of the radial cutsinthe disk 6 suitable cuts 8 are made to form the inner ends of thewings 7; and a flat horizontal portion is left between each pair of wings, as shown at 9.-

A rim l0 is secured around the outer circular edge of thedisk 6, the lower edge 0f said rim or ring extending slightly below the lower edge of the dependingwings 7 in order to protect said wings from injury by preventing them coming into contact with the bottom of the churn. Extending upwardly from this ring and being suitably disposed around it, are a suitable number of braces 1l. These braces converge at their upper ends and support between them, centrally over thedisk 6, a shortvertical tube 12, to the outer side of which said upper ends are rigidly secured. The dasher-shaft 4 passes loosely through thistube 12 and is loosely secured to thedisk 6 by a headed bolt 13 which passes through a central aperture in said disk and upwardly into the lowerend of the said shaft. By reason of this loose connection of the dasher-head 5 with the shaft 4, and thealternating wings 7, said dasher-head will revolve in one direction when it is being raised, and in the opposite direction when being forced down through the cream and will thereby produce a great agitation of the cream which will produce the butter in' a very short time.

As it is desirable to lock a revoluble dasher against rotation in order to collect the butter before raising it out of the churn we have pro- -Vided a simple `and efficient lock which consists of a piece of spring wire bent to form the eye 15 and two divergingspring arms 16. Astaple 17 loosely secures the lock to the dasher-shaft by passing through the eye 15 and into the dasher-shaft close to theshort tube 12, and preferably below said tube, and in such a position that the arms of the lock may be sprung into notches 1S formed in the adjacent edges of two adjoining braces 11. When said arms are sprung into thenotches 18, the dasher-head will be securely locked against rotation. l,

In order to raise the butter from the churn we provide a shallowperforated receptacle 20, which lits the interior of the churn and rests on the bottom thereof. Extending upwardly from this receptacle, and by means of which the receptacle is raised, are a suitable number of bars 2l, and these bars are connected at their upper ends by aring 22. These bars also form guards which prevent the dasherhead from striking the sides of the churn when in operation.

Having thus fully described our invention, what We claim is- 1. A churn-flasher consisting of a shaft, a rotatable dasher-head secured to the lower end thereof, and aspring-catch secured to the dasher-shaft and adapted to engage the dasher-head and temporarily lock it against rotation ou the shaft, substantially as described.

2. A churn-dasher consisting of a shaft, a rotatable dasherhead secured to its lower end, upwardly extending braces secured to said dasher head, atube 12 supported by said braces and through Which the dasher shaft passes, and a 'spring catch secured to the dasher-shaft and adapted to engage the braces of the flasher-head, substantially as described.

3. A churn-flasher consisting of a shaft, a

rotatable dasher-head secured to its lower end, upwardly extending braces secured to said dasher-head, atube 12 supported by said zo braces and through which the dasher shaft passes, and aspring catch secured to the dasher-shaft and adapted to engage the braces of the dasher-head, said catch consisting of spring-Wire bent to form the spring-arlns 16 z5 and the eye 15, substantially as described.

In testimony whereot We afiixoursignatures in presence of two witnesses.
