IMPROVEMENT m cuumus.

Speeitication forming pari: of Letters Patent N0. 186,420, dated Januamy 23, 1877; applieationfiled May 19, 1876. o

T0 all wlwm z't may conoern Be i1: known that I, WHITLEY F. GRAY, of

Sherman, in Ehe oounlsy of Grayson an(l Staate of Texas, have invented new aud useful Improvernents in Ohurns, which improvements are fully Set forth in the following specification, refereuee beinghad to the' aeeompanying drawings.

The objeel: of my in vention is to oombine in a ehurniug-maehine snitablemeehanism whioh shall easily anal rapidly eonvert erea1n into tail by the sketches, Figs. 55 and 4, also the Stern in Figs. 5 and 6. v

I am aware that; ehurns have been macle square, ronnd, and in man y ol;her forms; theref0re I de not; elaim, broadly, any particular style for l:he ehurn proper, as it: will be readily seen that my dasher am] driving meohanism oan beeasily at taohed 130 the eover 0f any common churn, whether square or wund.-

'.[o the ohurn-cover 0 isfastened, by sereWs or otherwise, the base d, wbioh supports two pairs of uprights, eeand e e, that' a1e seoured together by a eross-bar als the top, from which downward, aboul: one-half their length, are notehes eorresponding in shape 130 those upon the under side 0f the plates ff. One of each of these plates is seoured to each pair of aprights by a holt passing between them. Ai; the upper end of eaoh of these plates is a bearing snpporbing a horizontal shaft, g, at

turned by crank E. The dash-stem c a is split through Ehe center fron1 the top downward more than one-half its lengbh, inlso whieh is plaeed a pieee of flat bar=iron i, whioh projeets oul: beyond fhe wood on eibher side, and

is secur6d in place by bandsjj ab the top and bottom. (More elearly shown in Figs. 5 and 6.) The part of dash-stern thus ironecl moves up and down in bearings F F, when 1notion is ixnparted to it through arm G, see ured at; its top, and eonneeting-rod H, eonneofning il: with movable crank-pin k -upon one of Ehe arms 01'? balance-wheel B. My annular dashe r A is ot' metal. The outer ring m and innei one n, also arme o, eonneet;ing the same, are arehed upon their underside, whieh, as it is l'aised up and down, oauses more o1 lese of the atamosphere within the ehurn so mix freely with the eream, the objeet of whieh is obvious.

I olaim as my inventionl. A metal dasher const-rueted with two annular arches, both being connected with two er more radial arme, that are also arched.

2. The dash-stem a, when split and ptovided with an iron bar, i, secured as shown audspeeified.

3. In a ehurn, the driving meohanism herein speoified, consisting of crank E, shaft D, gear c, pinion e, and balance-wheel B, supported by notehed uprights e e and e e, as herein shown, and for the purpose sei; forth.
