HENRY YV. LANPHERE, OF INDIAN LAKE, YORK.

CHURN.

SPECIFICATION forming part of Letters Patent. No. 495,202, dated April 11, 1893.

Application filed August 15, 1892.

To all whom it may concern:

Be it known that I, HENRY W. LANPHERE, a citizen of the United States, residing at Indian Lake, county of Hamilton, and State of New York, have invented certain new and useful Improvements in Churns, of which the following is a specification.

My invention relates to such improvements and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures.

Figure l of the drawings is a vertical central section of my improved churn, Fig. 2 is a similar view taken on the broken line 2 2 in Fig. l. Fig. 3 is a top plan view of Ythe skeleton step-plate the upwardly projecting arms being shown in cross-section.

A is the churn-barrel and Afthe churncover adapted to tit and close the open end of the barrel.

The dasher-shafts, B-, B-, are each rotary in bearings in the churn-cover and each shaft is provided with a plurality of dasherarms or beaters, B-, preferably arranged upon their respective shafts spirally and in such manner that the arms of one shaft alternate with those of the other shaft. Each is provided on its projecting end with a beveled gear, B2- adapted to mesh with, and be driven by, the beveled gear, C-, common to both, fixed upon the drive-shaft, C. The drive-shaft is provided with a crank-handle, C2-, and is rotarily supported in bearings in the brackets, 03- projecting from the supporting plate, C4 secured to the cover, as by screws, O5. The plate, (34- also forms bearings for the dasher-shafts and their gears B2- and prevents the rotary parts from wearing away the churn-cover.

The lower ends of the dasher-shafts are su pported in bearings BS- in the step-plate, D-, which is secured to the churn-cover by means of the upwardly projecting arms, D. Such Serial No. 443,107. (No model.)

arms are preferably integral with the stepplate and project through the cover, the projecting ends being screw-threaded and provided with nuts, D2-, whereby such arms are secured to the churn-cover. Washers, D3-, may be interposed between the nuts, D2-, and the churn-cover. The step-plate is thus adjustably connected with the churn-cover and any lost motion due to Wear of the parts one upon another may be compensated by means of the nuts, D2. The cover may be secured in place by means of the springclamps or hooks, A2.

By my improved construction, the entire beating mechanism is supported by the churncover and maybe Withdrawn from the churn by lifting the cover, thereby affording easv access to the dashers forthe purpose of cleansing the same. To cleanse the dashers, they may be supported in a barrel or tub containing water and given a few rotations by means of the crank-handle, thereby quickly and thoroughly rinsing the submerged parts.

By having the beating mechanism and its bearings wholly supported by the cover, I avoid the necessity of attaching brackets or bearing-plates of any kind to the interior of the churn-barrel; and when the cover and its connections are removed, the interior of the churn is left entirely free from projections of any sort adapted to secrete particles of butter or cream which would taint the churn. The step-plate is preferably made in the skeleton form shown in Fig. 3, with the laterally projecting arms, D4-, adapted to approximately fit the interior of the churn-barrel. Such arms bear against the inner wall of the barrel and prevent lateral vibration ofy the step-plate and dasher-shafts.

When desired the lower portion of the inner wall of the churn-barrel may be beveled or contracted, as shown at AS- to enable the skeleton-plate to lit the bottom of the barrel while it is adapted to be easily inserted in and removed from the upper portion of the barrel.

What I claim as new, and desire to secure by Letters Patent, is-

, In a churn,the combination with the churncover; of a pair of dasher-shafts and a drive- IOO shaft severally supportedby the cover; gear In testimony whereof I have hereunto set connections between the drive-shaft and dashmy hand this 25th day of July, 1892. er-shafts; a step-plate having a bearing-support for each flasher-shaft; and a plurality of HENRY W' LANPHERE' 5 arms proj ectng upwardly from the step-plate Witnesses:

and cach adjustably secured to the churn- WILLIAM ALDONS,
