T0 a/ZZ whom it may concern: 1

Be it known that 1,11 AMES SCOTT HUDSON, a citizen of the United States,residing atHighbridge, in the county of Jessamine and State of Kentucky, have invented certain new and useful Improvements in Churns, of which the following is a specification, reference being had therein to the accompanyingdrawin-gs.

p My invention relates to new and usefulim-` proveniente in churns; and its object lis'to provide a device of this character having means of novel construction for driving the same.

A further object is to provide a series of adjustable dashers for thechurn adapted to be rotated in opposite directions.

Another object of the invention is to employ auxiliary dashers adapted to be adjusted longitudinally of the shaft of the dashers.

With the above and other objects in View the invention consists in the novel construction and arrangement of parts hereinafter trated in the accompanying drawings, inwhich Y Figure 1 is a longitudinal section through the power of the churn and showing the dashers in elevation. Fig. 2 is an elevation of the churn-power. Fig. 3 is a longitudinal sec-y tion through the lower portion of the shaftof the dasher, showing the mechanism for adjusting the auxiliary blade.

Referring to the figures by numerals ofl reference, 1 is a churn body, upon whichgis mounted a casting 2, having recesses 3 and 4 extending thereinto near the top and bottom.'v thereof, and the upper recessl4 communicates with a vertical aperture 5, formed in the top ofthe casting. A recess 6 is formed within the upper wall of recess 3, and in vertical alinement with this recess 6 is an aperture 7, which communicates withan aperture 8, formed within the top 9l of the churn-body. A shaft 10 extends longitudinally through the casting 2 and through. the centersof the apertures 5, 6, and 8, and the upper end of this shaft is secured to a beveled gear 11, which is mounted within recess 4 and has a boss 12 thereon, which is revolubly mounted within the aperture 5. A disk 13 is revolubly mounted within the recess 3, and a boss lto a base-plate 26.

Serial-110.154,65@ (No model.)

14 extends upward from this disk and is revolubly mounted within recess 6, and a tubular extension l5 projects downward from the center of disk 13 and incloses shaft 10. This shaft is free to rotate within the disk 13 and its extension. A stem 16 projects from one sider of casting 2, and revolubly mounted thereon is a beveled gear 17, having a crank 18 connected thereto. This gear meshes with ther gear 11, before referred to, and has a concentric'tiange 18:L upon its inner face provided With te'eth 19, adapted to project into recesses 20, formed Within the periphery of the disk 13. 1t will thus be seen that when gear 17`is rotated by means of crank 18 the disk 13 and gear 11 will be rotated in opposite directions.

Blades 21 are secured to the lower end of shaft 10 at right angles to each other, and these blades are prevented from twisting upon the shaft preferably by forming a bead 22 upon each of them and `fitting the same within a longitudinally-extending groove 23, formed within the shaft 10. A threaded recess 24 extends longitudinally into the lower end of shaft 10 and receives an adjustingscrew 25, which is swiveled at its lower end Blades 27 are arranged upon this base-plate at opposite sides of the shaft, and each blade has a downwardly-extending lug 28, which is inserted into the base-plate and has an inwardly-extending ear 29, which is slidably m-ounted within a slot 30, formed longitudinally within the outer face of the shaft. It is obvious Athat when the screw 25 is rotated the base-plate-26 and the blades 27 will be moved either from or toward the lower end of shaft 10. A blade 31 fis secured to vone side of the shaft 10 in aposition parallel to thevblades 27, and it is obvious that when the said blades 27 are moved downward away from the lower end of shaft 10 they will form practically a continuationr of blade 31. I n

A ring 32 incloses the tubular extension 15 and has a circular flange 33 at the center thereof having suitable'clamping means 34 therein for securing the ring' to the extension 15.- Secured to opposite sides of th'ering 32 and depending therefrom are blades V35, each 40f which has a longitudinally-extending slot 36 therein. Each of these slots is enlarged ICO at a point between its ends, as shown at 37, to permit the insertion therethrough of a slide 25S. Loosely mounted within this slide is a screw 39, which is rigidly secured to an extension-blade LlO,and this extension-blade can be firmly clamped tothe blade 35 by screwing a thumbnut 4l upon the screw 39. It will be seen that when the crank 18' is rotated the blades 35 and 40 will be rotated in one direction while the blades 2l and 27 will be carried in the opposite direction. The blades can be adjusted so as to cover a desired area v within the churn, and by adjusting,` theblades 27 from or toward the shaft l0 the dashers may be adapted for use in churns of different sizes. The power mechanism employed is extremely simple and compact in construction, and the parts can be readily assembled and secured together without the use of screws, bolts, and similar fastening means.

In the foregoing, description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make all such changes as fairly fall within the scope of my invention.

Ilaving thus fully described the invention, what is claimed as new is l. In a churn, the combination with a revoluble shaft, a tube loosely mounted thereon and means for rotating the shaft and tube in opposite directions; of a base-plate, an adjusting means connecting said plate to the shaft., blades slidablymounted upon the shaft and secured to the base-plate, and adjustable blades connected to the tube and movable therewith.

2. In a churn, the combination with a shaft, a tube mounted thereon and means for rotating the tube and shaft in opposite directions; of a baseplate, means for adjusting said plate from or toward the end of the shaft,

blades secured to the shaft, blades secured to the base-plate and parallel with one of the first-mentioned blades and adapted to be adjusted with the base-plate, and adjustable blades connected to, and revoluble with, the tube.

3. In a churn, the combination with a shaft, a tube thereon and means for rotating the shaft and tube in opposite directions; of blades secured to the shaft, longitudinallyadjustable blades upon the shaft, a baseplate connected to said adjustable blades, an adjusting-screw connected to the base-plate and engaging the shaft, and adjustable blades connected to, and revoluble with, the tube.

4. Inachurn, the combination with a shaft, a tube thereon and means for rotating the tube and shaft in opposite directions; of lougitudinally-adjustable blades upon the free end of the shaft, a ring inclosing and secured to the tube, longitudinally-slotted blades secured to the ring', extension-blades adjustably mounted upon said slotted blades, and means for securing the extension-blades in adjusted position.

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