IMPROVEMENT IN CHURNS.

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

To all 'whom fit may concern Be it known that I, JOHN I. GHEATHAM, of Athens, in the county ot' Clark, and State oi' Georgia, have invented an Improved Churn; and I do hereby declare that the following is a. full and exact description thereof, reference being had to the accompanying drawings, making part ot' this specitication- 'Figure 1 being a side view of the, churn.

FigureQ, a front view ot' the same.

lFigure 3, a view showing the adj listing-slot in the crank-wheel, and the parts immediately in connection therewith..

Like letters designate corresponding the figures.

My improvement consists in an arrangement for imparting an easy vertical reciprocating motion to the dasher of a churn, by means of a crank, through the medium ot' a sliding gate.

Another feature ot'improvement consists in a methodv of adjusting the length and position of the stroke of the dasher, to suit the amount of cream in the churn.

Let A represent a support for the driving-gear, and B, a. dasher-churn, of the ordinary kind.

'lwo uprights, O O, properly connected above and below, constitute an open trame, to support guide-rods or ways g g, on which a sliding gate or sash, J, trav'- erses vertically.

The driving-gear consists of a crank, H, which drives a spur-wheel, G, this wheel matching into a pinion, F, on a shatt, E.

On the end of this shaft is a crank-wheel, D, which may also serve asa ily-wheel; and it imparts a'vertical reciprocating moti'onto the gatev or sash J, by means parts in al1 of Of`a connecting-rod, a, extending from the crank-pin b, On the said wheel l), to a corresponding pin, c, on a bar, 1, which projects downward from the gate, and forms a, part thereof. l

The motion is imparted to the dasherrod M by connecting its upper end with a projecting piece, L, which forms a part of the same sliding gate, J.

By the above-described arrangement,- I interpose the sliding gate J between the crank-wheel D and the dnsher-rod M, and by this means obtain a much steadier and easier movement ot' all, the parts than would resuit from the direct connection ot' the dasher-rod and crank-wheel. Thisarises partly from the greater length of connecting-rod a than it' it joined immediately with the dasher-rod, and partly from the act-ion of the sliding gate upon the dasher-rod being always direct and in line with its motion.

The dasher-rod M has a series of holes, -i t', in' its -upper end, through one of which, and a corresponding centre of the crank-wheell), by means oi' the radial slot d and set-screw l, as represented in` tig 3, or the equivalent thereof. v

This invention is also applicable to washing-ma4 chines, and other machines requiring a similar reciprocating mot-ion.

\Vhat 'I claim as my invention, and desire to secure by Letters Patent, isfi The combination and arrangement of the crankwheel D, with its adjustable crank-pin b, the iuterme diate sliding gate J, and dasher-rod M, adj nstable to different heights on the gate, substantially as au-.l for` the purpose herein speciied.

The above specification of my improved churning machine signed by me, this 14th day of October, 1868.
