To all whom it may concern.-

Be it known that I, JOHN C. MeVEY, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented new and useful improvements in Ohurns, of which the following is a specification.

This invention relates to churns.

The object of the invention is to improve the construction of such devices.

With the foregoing object in view the invention resides in the exact details of 0011- struction and in the precise combination of parts hereinafter described andv specifically claimed.

Figure 1 is an end elevation of my improved churn. Fig. 2 is a central vertical longitudinal section therethrough. Fig. 3 is a vertical transverse section. Fig. 4 isan enlarged longitudinal section through the mechanism employed for transmitting rotary motion from the driving mechanism to the dasher. Fig. 5 is an enlarged section through a portion of one of the gears of the driving mechanism and showing the manner of connecting the crank thereto, and Fig. 6 is a perspective view of the supporting-plate of the driving mechanism.

Referring to the figures by numerals of reference, 1 is a receptacle having the bottom thereof preferably formed of a central horizontal portion and. inclined side portions 3, and this receptacle is supported by legs 4; andv has a plate 5 secured to one end in any suitable manner. This plate is provided with. a sleeve 6, which extends through one end of the receptacle 1. A stem 7 extends laterally from one end of the plate 5 and forms a bear- .ing for a hub 8, from which extend arms 9, which are curved. inward and formed integral with a ring 10, having teeth. 11 upon its inner face. One of the arms 9 is recessed, as shown at 12, for the reception of a pin 13, which extends from a crank 14, provided with a handle 15. in the recess 12, preferably by means of a screw 16, which extends through crank 14 and into engagement with the arm 9.

Revolubly mounted. within the sleeve 6 is a tubular stem 17, which is keyed. or otherwise secured at its outer end to a gear 18, which meshes with the teeth 1 1 on ring 10. The inner end of the tubular stem 17 is formed integral with. an angular head 19 for the purpose hereinafter more fully described. A red. 20 is revolubly mounted in stem 17 and has a This pin is retained withgear 21 keyed or otherwise secured to its outer end, and this gear meshes with teeth 22, formed upon a ring 23, which is integral with the arms 9, but in a plane removed from the ring 10. The inner end of rod 20 has a tapered angular head 24, which is preferably spaced from the stem 17 by a washer 25. This head, as well as head 19, is adapted to be seated within a recess 26, formed in one end of a rectangular frame 27, revolubly mounted within the receptacle -1. Head 19 fits snugly within said recess and is adapted to rotate the frame 27 therewith. The opposite end of the frame is supported by a shaft 28, which is revolubly mounted within the two ends of the frame and is supported at one end by a set-screw 29, and the other end is engaged by the head 2 1. 'Wear-plates 39 are detachably connected to the ends of shaft 28 and. form bearings for the head. 24 and the said screw 29. As shown by dotted lines in Fig. 4, these plates can be fastened in position by means of screws 31; but any other securing devices may be employed. The ends of the frame 27 are beveled in opposite directions, as shown in Fig. 3, so that as the frame rotates the inclined inner faces of the ends will be brought directly into contact with the liquid within the receptacle and will tend to throw it inwardly. The cross- .bars 33 of the frame are also beveled so as to first present the inclined faces thereof to the liquid as the frame rotates, and thereby throw the liquid inward toward the center. Blades 3d extend from the shaft 28 and are inclined, so as to throw the contents of the receptacle laterally as the blades rotate.

To operate the churn herein described, the handle 15 is grasped. and rotated so as to cause the two rings 10 and 23 to rotate in unison. The teeth on ring 10 will rotate the gear 18 in one direction, While the teeth on ring 23 will rotate the gear 21 in the opposite direction. As the heads 1.9 and 24 are connected to the gears 18 and 21, respectively, .it will be understood that the parts engaged. by these heads Will rotate .in opposite directions, thereby thoroughly agitating the contents of the receptacle. All of the parts of the churn can be readily detached. and. replaced, and by providing driving mechanism such as de scribed a durable and effective device is produced.

Having thus described the invention, what is claimed as new is- In a churn, the combination of a receptacle having a plate secured upon the exterior of one of the end walls thereof, said plate being provided with an outwardly-projecting integral stub-shaft and an inwardly-projecting sleeve extending through said wall, a tubular stem revolubly mounted Within the sleeve and having a squared head at its inner end, a rod revolubly mounted Within the tubular stem and having a rectangular head at its inner end, a shaft journaled at one end upon the casing and formed at its opposite end with a socket receiving the head of the rod, a dasherframe revoluble on said shaft and having a squared socket receiving the squared end of the tubular stem, a small gear-wheel upon the outer end of the rod, a relatively larger gear-wheel upon the outer end of the tubular stem and located between said small gear-wheel and the plate and close to the latter, and a drive-gear conprising a hub mounted upon the stub-shaft and provided with radial arms having their outer ends turned inward toward the receptacle, a

large toothed ring integral with the inbent ends of the arms and meshing With the gear on the tubular sleeve, a smaller toothed ring integral with the arms and disposed thereon between the hub and inturned ends, said smaller ring being arranged in a plane outside the plane of the large toothed ring and meshing with the gear on the rod, the arms being curved outwardly beyond the small toothed ring and their inbent outer ends to form a space for the reception of the gear on the rod, the construction being such that the drive-gear incloses the associated shaft and dasher-gears and mountings and lies in close proximity to the Wall of the casing, and a crank fixed to one of the arms and its inturned portion, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
