IMPROVEMENT IN CHURNS.

Spccification forming part of Letters Patent No'. 54,878, (lated May 22, 1866.

To all whom t'i may CORCML:

Be 't known that I, BENJAMIN S. FLETCHER, of Gornish, in the county of Sullivan and State of New Hampshire, have invented a new and useful Improvement in Churns; and I hereby (leci-are that the following is a full and exact description ot' the construction and operation of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Figure l is a broken side view. Fig. 2 is a long'tudinal sectional view. Fg. 3 is a crosssectional View; and Fg. 4 is a View of a portion of a shaft, showing an end View ot' the breakers.

I an aware that there are other churns patented and in use which, in some respects, are similar to mine, yet in other respects mine is cssentially different from any yet patented, especially in the form, position, and operation of the dashers and breakers.

I construct my churn of wood `or any other suitable material, of a square form, with a detachable lid or cover, nearly as large as the top of the churn, which is held in its place by buttons. Within the lid is a glass plate, through which the process of churning nay be observed enabling the operator to know when the operation is completed without removing the lid. Within the churn is a shaft extending horizontally from side to side, and which is furnished with flies or dashers. There is also within the churn a series of breakers, between which the dashers pass as they revolve' The lower ends of said breakers rest in depressions in the bottom of the churn, corresponding in shape and size with the ends thereof. On the upper ends of the breakers necks are constructed, which rest in collars in a crosspiece across one of the upper ends of the churn. Said breakers are held in place by a rod which passes through the upper part of the churn from side to side and across the necks thereof, but they may be removed from the churn by withdrawin g the rod. When in the churn they rest at an angle of about siXty-five degrees.

The transverse forn of the dashers and 4 breakers is that of an isosceles triangle, and their distance apart is a little more than the length of the short angle, and as the dashers revolve with the long angles in front they work together easily and press the erean closely. On one end of the shaft o which are h'xed the dashers is a journal which works in a journal' box placed in the side of the churn near the center. In the other end of the shaft is a square socket, which is adapted to the inner end of a short metallic shaft which extends through the side of the churn, and on the outer end ot' which is fixed a pinion which gears into a larger encycloidal wheel revolvi ng on a pivot fixed firmly to a ele-at attached to the side of the churn. To the large wheel is attached a handle tbrning a crank by which the ma chinery is operatcd. Around the short metallic shat't is a groove which adrnits the point of a small metallierod, which passes up through the cleat to which the pivot on which the large wheel revolves is fixed. This rod constitutes a key, which prevents the short shai't from slippin g out while the inachinery is in operation and becoming detached from the shaft on which the dashers are fixed; but it may be withdrawn when it isdesired to withdraw the shaft for the purpose of removing the dashers from the churn.

A A, Figs. 1, 2, and 3, represents the body of the churn; b b, the cover, and 0 the glass plate in the cover.

B, Figs. 1 and 3, represents the eneycloidal wheel gearing with the pinion O, Fig. 1.

D, Figs. 2 and 3, is the shaft on which is 'fixed the flies or dashers E E. On one end of this shaft is the journal cc, Fig. 3, which revolves in the journal-box e. In the other end of said shaft is a socket adapted to the square and of the short shaft F. i is the groove in said shaft, in which rests the key Fc,'Figs. 1 end 3.

G G, Figs. -2 and 3, are the breakers, the necks of which are held in the collars in the cross-piece f by the rod g.

My churn nay be constructed so that a cranl; may be attached to the outer end of the shaft Fwhen a slow motion of the dashers is desired; or the wheels may be dispensed with entirely.

In operatin g my churn the form of the dash-` ers is such that they enter the crean easily and press it closely in passing between the breakers causing a sharp current and a rapid breaking of the oily globules, and thus completing the ehurning in. a short; time.

After the churning is completed the shaft D may be removed from the chur by removing the wheel B from the pivot and raising the key Ic and removing the pinion C.

The breakers Gr G may be removed by withdrawing the rod g, when there will he no obstruction to the gathering of the butter or the cleansing ot' the churn.

The points of difference between my churn and others patented is inthe form of the dashers E E and the breakers Gr Gr, and the posi- 'tion and manner in which said breakers are placed within the ehurn.
