WILLIAM W. STILWELL, OF OXFORD, WISCONSIN vLetters Patent No. 111,490, dated January 31, 1871.

IMPRoi/ EMENT iN cHunNs.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom, 'it may con-cern Be it known that I, WrLLrAM W. SrILWnLL,-ot

Oxford, in the county of Marquette and iu the State ol' \Visconsin, have invented certain new and useful Improvements in Ghurns and do hereby declare thatthe following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of vreference marked thereon making a part of this specification.

'lhe nature et' my'iuve-ntion consi/sts in the construction and arrangement of a churn, as will be hereinafter fully set forth.

In order to enable-others skilled iu the art to which'ruyinvention appertains to make and use the. same, I will now proceed todescribe its construction and operation, referring to the annexed drawing, in which- Figure l is a longitudinal vertical section of my churn;

Figure 2 is a bottom view of the dasher;

Figure 3 -is a side view of the frame placed on the lid, and in which part of the mechanism for operating the dashers is inserted; and

Figure 4 is a view showing the mode of connecting the flasher-shaft to the swivel.

A represents the tub, of any suitable dimensions, whiclris provided with a false bottom, B, forming a chamber, C, below this false bottom a'nd the regular bot-tom of the tub.

lhe chamber or reservoir C is for the purpose of holding hotor cold water, to temper the cream.

The upper orfalsc bottom B may be made 'of metal iu a practical churn, which will much facilitate a right temperature.

There is a funnel, I), attached vto the upper partof said reservoir, through which water. may be poured to press against the upper bottom.

Likewise, a, faucet, E, below, to draw off the water aft-cr the right temperature has been acquired.

- The tub A seovcred by the lid G,a portion of which is hinged for the purposeof erta-mining the' thermon'ieter iu rela-tion to the temperature of the cream.

The tlicrnionieterfslides in a groove on the inside of the tub, as indicated by dotted lines at a, in 1.

. On the cover G are secured two standards, H H, the npperends of which are cut with square tenons, Il (1.

These tenons are passed through mortises in a cross-bar, I, which thnseonnects the two standards. Pins are then put through thc tenons 71 b, securing the cross-bar I.

.it a suitable height from the cover G, on the innc1'shles it'thc standards II H, are horizontalgrooves, in which is inserted another crossbar, J, and which bur is secured in place. by keys d d, moving in vertical grooves on the inner sides of the standards,as shown in fig. :3.

Between the cross-bar J and the cover G, and having 4its bearings in a bon` on said cover, is placed a hub, K, having beveled or miter cogs on the outside.

This hub gears with a large imiter-wheel, L, upon theinncr end ofa crank-shaft, M, which has its bearings in suitable standards rising from the covei' G.

Through the hub K passes a shaft, N, which is square for a suitable distance, and the upper end round where it has to move through the upper crossbar I. l Y

This shaft passes downward into the tub A, and at its lower end is secured a shaft, O, of larger diameter.

On this shaft O are secured the dashers P P, which are fan-shaped, as shown in g. 2, whereby they occupy more space in the cream and force a greater quantity of air in at the same time.

' These fan-shaped dashers are arranged spirally on the shaft O, and are beveled. downward on the flaring side for raising the cream 'wlien the dashers are in motion.

They are hollowed out ou the under side for forcing atmosphere into the cream in their vertical motion, with small orifices, i t', in the top oi' the dasher for emitting air into the cream.

The upper end of the shaft N, above the cross-bar I, passes i'nto a swivel, 7i, where it is attached by means of an iron-key, c, having an elongated slot, as shown in fig. 4. of the swivel into a groove on the shaft, which attaches the two together.

To the swivel h is hinged or pivoted a pitman, R, or crank, attached to the wheel L, so that by the turn-y ing of the crank-shaft M the dashers obtain not only a rotating but also a vertical] y reciprocating motion.

Having thus fully described my invention,

\Vhat I claim. as new, and. desireto secure by Letters Patent, is-

1. The fan-shaped dashers I P, arranged spirally on a dashensliaf't, beveled downward on one side and hollow-'ed out on their nuclei side, with orifices t' yi through the top, all substantially as and for the purposes herein set forth.

2. The arrangement of the shaft N, swivel h, and

yslotted key c, substantially as shown and described.

o. The combination of the tub A, )artition B,

water-reservoir C, funnel I), faucet E, fan-shaped dashers l I, and the mechanism herein described for operating said dashers, when all the parts areeousti-noted and arranged substantially in the manner and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 29th day .of September, 1870.
