' OHURN. r i

To all whom it may concern:

Be it known that I, ALFRED J. ANDERSON, a citizen of the United States, residing at Wylie, in the county of Red Lake, State of Minnesota, have invented certain. new and useful Improvements in Churns andI 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 pointed out in the appended claim, it beingunderstood that changes in the form, proportion, size, and minor details may be made within the scope of the claim without departing from the spirit or sacrificing any of the advantages of the present invention.

In the accompanying drawings,'Figure 1 is a vertical sectlonal view illustrating'my inventlon.

Fig. 2 is a detail perspective view of one of the elements forming two dashers of a set of the latter. view of one set of dashers.

Referring now more particularly to, the accompanying drawings, the reference characterl designates the body of the churn, having a journal-bearing 2 arranged centrally and upon the inner surface of its bottom for the reception of the lower end of the dasher-shaft 3, whose upper end passes through a bushing 4 in the cover 5 and is fixedly secured to the latter in any suitable manner, there being a pinion secured to the bushing 4 and arranged or rotation upon the outer face of the cover 5. It will be seen thatthe upper end of the bushing has a laterally-directed flange 6, between which and the upper surface of the cover 5 the inion rotates in amanner to be hereinafter ffllly explained.

Fixedly secured upon the top of the cover 5 is a V-shaped bracket 7, having alining per-- forations 8 for the reception of a revoluble shaft 9, provided at its free end with a crankv Specification of Letters Patent.

Application filed June 1, 1905. 'Seria1N0. 2 63,278.

Fig. is a top plan wheel, 10 and having a gear-wheel 11 fixedly secured to its opposite end for mesh with the pinion- 6 of the dasher-shaft 3. 7

From the foregoing it will be readily seen that by grasping the handle 12' of the crankwheel 10 the shaft'9 will rotate the gearwheel v1 1, which is in mesh'with the pinion 6,

to rotate the dasher-shaft 3', and reference to the drawings will disclose that this shaft is provided with a series of shoulders 13-, 14, and 1 5, resultingin the formation of a dasher-shaft of greater cross-sectional diameter in steps toward its lower end. 7

Four dashers are arranged u on each shoulder 13, 14, and 15, the dashers eing of peculiar formation. In other words, two elements compose the four dashers, the said elements crossing each other at their oint of intersection with the dasher-sha t. It will be seen that one of these elements 16 has its op- Patented.1)ec. 5, 1965 a posite ends enlarged, forming the oppositelydisposed dasher-blades 17,. provided with perforations 18, the said blades being bent at a direct right angle to the plane of the intermediate portion 19 of the member from which they are formed, thesaid intermediate portion 19 being provided with a rectangular opening 20, whereby the element of which the blades are formed may be fitted upon the shaft, which latter is referably rectangular in cross-section. It wi 1 be seen, too, that the intermediate portions of each element form ing the blades cross each other, resulting in one being dis osed directly upon the other at their reduce intermediate portions. These 'elements or dashers com rise one set, and it I will be understood that t ere is a set of dashers, such as those described, disposed upon each of the shoulders 13, 14, and 15. If desired, a small pin or other suitable element 21 may pierce the dasher-shaft immediately above the other element forming the-dashers, so as to prevent longitudinal movement of the latter along the shaft. Of course the trunnion 22 at the lower end of the dashershaft 3 is arranged centrally ofthe latter and is of just slifiicient length -to'hold the lower end .face of the dasher immediately-above the journal-bearing'2.

By reason of my peculiar formatlon of dashers the cream is turned upwardly through centrifugal force, causing a rapid progress in IOO the churning of the butter, and reference to the drawings will disclose that if I desire I may disposea small faucet 23 in the bottom of the churn-body 1 for the purpose of extracting or withdrawing buttermilk from the churn during the churning operation.

It will now be understood from the manner in which I state that the dasher-shaft is operated that the respective sets of dashers fit tightly upon the shaft in engagement with the corresponding shoulders of the latter, and when it is desired to remove the dashers and their shafts from the interior of the body 1 it is simply necessary to lift the cover 5 from the top of the body, when, by reason of the dasher-shaft being fixedly secured to the bushing of the cover and upon which the faucet-pinion is mounted, the shaft may be readily disengaged from its bearing 2 and easily removed from the body for churning purposes.

W' hat is claimed 1s 7 In a churn, a body, a dasher-shaft journaled in said body, the shaft having a series of enlargements to form shoulders arranged one above the other, dashers arranged upon the shaft and supported by the said shoulders, means for operating the shaft and its dashers, and an outlet at the bottom.

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