Application filed July 31, 1908. Serial No. 446,325.

To all 'whom it may concern:

Be it known that we, RUrUns B. COLLIER and JOHN S. MARTIN, citizens of the United States, residing at Yeager, in the county of Hughes, State of Oklahoma, have invented certain new and useful Improvements in Churns; and we do hereby declare the following to be a full, 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.

The present invention relates to improvements in churns, and it has for its principal object the production of an exceedingly simple clamping device by means of which the dasher mechanism may be attached to a crock, jar, or other receptacle of any ordinary type which is designed to serve as the body of the churn, thus obviating the necessity for the employment of a specially formed body, or for the permanent attachment of the dasher mechanism to the body.

To this end, the invention briefly described, comprises a metal cover plate having a series of straps hinged thereto and adapted to be swung downwardly against the sides of the receptacle, and a chain designed to be passed through the staples or eyes with which the straps are provided, the straps being held against the sides of the receptacle by means of a retractile coil-spring which forms one of the members of the chain.

The invention further resides in the particular devices employed for imparting a vibratory movement to the dasher shaft.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which corresponding parts or features, as the case may be, are designated by the same reference numerals throughout the several views.

Of the said drawings, Figure 1 is an elevation of the complete invention. Fig. 2 is a plan view. Fig. 3 is a vertical section taken centrally through Fig. 2, on the line 3-3 thereof. Fig. 1 is an enlarged detail view, illustrating the lever for locking the ends of the chain together. Fig. 5 is an enlarged fragmental detail view, illustrating the spring which is included in the chain.

Referring more particularly to the drawings, 1 designates generally a receptacle which is designed to serve as the body of the churn, and may be of any ordinary type, and 2 its cover. This cover is in the form of a circular metal plate which is formed with a central opening through which the dasher shaft 3 extends, said shaft having the lower portion thereof split or bifurcated so as to receive the dasher plate 4.

Upon the upper face of the cover plate, is mounted a metal bracket comprising a body portion 5, and front and rear pairs of legs 6 and 7, the body portion being formed with an opening which alines with the opening in the cover plate. The free ends of the pairs of legs above referred to are turned outwardly to provide feet which are bolted or otherwise securedv to the cover plate. The dasher shaft, which likewise extends through the above-mentioned opening in the body vof the bracket cariies a sleeve 8, whose lower end is formed with a gear 9 arranged to rest upon the upper face of said body portion, the sleeve being retained in place upon the shaft by means of a thumb screw 10 or similar device which is fitted in an opening formed through the sleeve and has its inner end impinging against the shaft, owing to which construction, it is possible to regulate the extent to which said shaft projects into the receptacle.

The sleeve 8, and in consequence, the dasher shaft, is held against upward movement by means of a plate 11, which is disposed directly above the bracket body 5, and is secured thereto at one end by a threaded bolt 12, and at the other end by a headed pin 13. This plate is likewise provided with an openingl through which the sleeve 8 extends. The pin 13 has rotatably mounted thereupon an annular member 14, a portion of whose periphery is formed with teeth 15, arranged to engage the teeth of the gear Q, above referred to, said member being likewise interposed between the plate 11 and the bracket body, and being formed with a diametrically-arranged. strap 16 provided with a central opening through which the pin 13 passes, said strap projecting at one end beyond said member and having secured thereto at such point a handle 17. Said member, its teeth, and its strap thus unite in forming a gear segment, the oscillation of which will impart a vibratory movement to the dasher shaft and its plate 1, as will be apparent, the movement of said member in either direction being limited by the contact of a stop 18 with one or the other of the rear legs 7. This stop, which is disposed against the under face of the rear portion of said annular member, is formed of a short strip of heavy wire whose upturned ends are received in openingsformedin said` member.

5 At its periphery, the cover 2 carries a series of hinged straps 19 which are arranged tofbe swung downwardly against the sides of the receptacle. Each of these straps is formed with a staple 20, or eye, through which is passed loosely, a chain V21, one end of the chain being provided with a locking lever22, and with a ring 23 located adjacent the same. @ne part of said chain is formed by are- Y tractile coil-spring 24, whose ends are connected to the adjacent links. The chain and its spring are provided for the purpose of clamping the cover in place upon the upper edge of the receptacle, against the sides of which latter the straps 19 are arranged to be w20 moved, as above stated. In attaching the cover, the lever 22 has its free end passed through the link at the other end of the chain after which said lever is swung backwardly, ,i and its end then passed through the ring 23. 25 When the various parts are in this position, the spring, by reason of its tension upon the chain, will serve to press the straps tightly against the sides of the receptacle, and thus Y prevent their outward movement, until the V30 ends of the chain have been disconnected by the release of the lever from the ring and from the link through which it is passed. It will thus be apparent that the cover may be used with receptacles of various sizes, since A the straps may be swung inwardly or outwardly prior to the connection of the chain ends, to permit them to contact with the sides of the receptacle.

The dasher plate 4 which is carried by the `V4K0 shaft 3, as above stated, is preferably formed of a single strip of sheet metal whose vertical edges are provided with inwardly-extending notches, the formation of the notches resulting in the provision of tongues 25. These tongues are preferably curved or bent in opposite directions, the tongues on each side of the shaft being thus offset from or disposed in staggered relation to each other. The entire dasher plate, as well as that portion of the shaft to which it is secured, may if desired,

be glazed or coated with a vitreous enamel.
