CHURN.

SPECIFICATION forming part of Letters Patent No. 225,832, dated March 23, 1880. Application filed August 6, 1879.

To all whom it may concern:

Be it known that I, JOSEPH D. HoBBs, of Burlington, Des Moines county, Iowa, have invented a new and useful Improvement in Chorus, of which the following is a specification, in which reference is made to the accompanying drawings, showing, ll]- Figure 1, a top View; in Fig. 2, a section on the line at 00, Fig. 1; and in Fig. 3, a detail view of the ventilator.

My invention relates to churns wherein the dashers are made to reciprocate by means of levers connected to shafts to which the dashers are attached; and my invention consists in combining with a churn-body having inner rounded corners to facilitate cleansing a pair of vertical rock-shafts carrying a series of dashers or paddles, cranks to operate the rod, and a pivoted equalizer having slots in which pins attached to the cranks play, the churn being constructed, arranged, and operated as more fully hereinafter explained.

The drawings represent a square churn, with its box or body of wood, with four legs, N N N N, one on each corner, which legs begin at the top of the churn-box and extend a short distance below it, thus forming the inside concave corners, O O O O, of the churn. The four sides-of the churn-box are bolted into grooves in the legs N, 850., by eight long bolts running entirely through the box and fastened at the ends by burrs-four bolts at the top of the box and four at the bot-tom. Within the churn are two dashers, A A,joined to the shafts B B. These dashers A A extend about two-thirds across the churn from opposite corners where the loose shafts B B are placed.

These dashers are cut into saw-teeth nearly the entire length of the dashers, and are in height about equal to one-half the height of the churnbox. These shafts B B work on gudgeons on the lid from the shafts are ventilators K K. In the center of the lid is a gudgeon, on which works a metal equalizer, M, in each end of which is a short slot, L L, in which work gudgeons E E of the levers or cranks D D. These levers or cranks have at one end a short slot, F F, which fits over the hooks G O of the shafts B B. These levers are worked by handles G G.

The churn operates as follows: Put the gudgeons of the shafts B B on the gudgeonblocks on bottom of the churn; set the lid over the churn, putting the shafts B B through the wooden boxings H H; put the slots F F of the levers or cranks D D over the hooks O O on the shafts B B; lower the levers till the gudgeons E E pass into slots L L at each end of the equalizer M. By working the levers or cranks D D backward and forward the shafts B B, to which the dashers A A are attached, move back and forth horizontally across the churn.

The churn may be taken apart, tightened, or loosened by properly adjusting the bolts.

I am aware of the patent granted D. D. Frankfoder, March 21, 1871, in which are shown dashers attached to rock-shafts and operated by a series of connecting-levers; and I do not claim the invention shown therein, my device possessing the advantages of greater simplicity of construction, whereby it may not only be operated with greater case but manufactured at less expense. Therefore What I claim is- In a churn having inner rounded corners for the purpose described, the combination of the shafts B B, the cranks D D, having pins, and the centrally-pivoted equalizer M, slotted longitudinally on each side of the center pivot, whereby the alternate reciprocation of the cranks operates the dashers, substantially as described and shown.
