Letters Patent No. 102,354, dated pm'l 26, 1870.

IMPROVEMENT 1N 'cHURNs The Schedule referred to in these Letters Patent and making part of the same.

I, CHARLES T. Annnnsom'ofillarksburg, in the county of Montgomery and State of Maryland, have invented a new and useful Improvement in Ohurns, which invention is described as follows.:

Nature and Objects' of the Int-eration.

In the accompanying drawings- Figure 1 is a vertical longitudinal section of lny imgrovSedcburn in the plane indicated by the line a; x,

Figure 2 is a vertical section at y y, iig. 1;

Figure 3 is a horizontal sectionat z z, iig.v 1.

Similar letters of reference indicate corresponding parts in all 'the gures.

The -body of the churn is dividedinto two chambers, A A,vby a partition, C, which is formed .near its u'pper ypart with a large aperture c, and below with a number of small apertures, c t.

The base B is made hollow, and is preferably formed of two'plates'oi' zinc or other metal, the intervening chamber b serving for the reception or circulation of steam or hot water, to keep the temperature of the cream up to a proper degree in cold weather, or for l cold water, to keep it cool in hot weather.

The flashers consist of horizontal and oblique plates D and D', the lower plates D being horizontal, so as to act with direct percussion and pressure upon the cream in descending, and the upper plates D oblique, so as to pass easily through the' cream in ascending. These upper plates are arranged either singly or in pairs, as'shown.

Both the lower and upper plates are perforated, in

.order to produce greater flictional action on the cream.

The dasher-rods E and E receive avertical reciproeating motion from levers F F', which are fulerummed respectively at f and f', and are connected at their shorter ends, by rods G G', to a doublevhand-lever, H, which is fulcrummed at h to a standard, I.

.T represents'a thermometer, arranged in any suit` able manner for the purpose of indicating the temper- Aend to the other' of its vertical stroke.

. Operation. l It will readily be seen that the rods G G', in connection with theshort arms of the levers FF', will act on the principle of toggle-levers, so that a given movementof the hand-leverH will impart greatly-increased motion to the long arms of the levers F F.

A slight movement of the hand-lever in either direction will thus suiiice to throw each dasher from one rlhis renders the Operation of churning very easy, and, by reason of -the combination of the levers and the vconnection of rthe two dashers, the `necessity of any lifting action on the. hand-lever'is entirely dispensed with.

Adepression of the ends of the hand-lever alter'- nately is all that is required to throw the dashe'rs in both directions. The chief churning action is by each dasher exerted in its descent, its lpwer surface being at right angles to its line of motion.`

In ascending, the oblique boards or plates D'deflect the body of cream that is above them, so as to pass easily through it and avoid'throwing it forcibly upward against the churn-top.

The large opening c in the partition C, allows the cream thus raised to pass freely from one compartment ofthe churn to the other.

Claims.

The following is claimed as new: 1. The paired dashers, working in separate chambers, and each composed of a horizontal bottom plate, l
