CHARLES H. sMi'rHor BOSTON, MASSACHUSETTS,

Letters Patent No. 85,970, dated Janna/ry 19, 1869. I

IMIPROVVELIENT IN CEURN AND vBUTTER-ViIRKER G'OIVIBIII'QEID.`

The Schedule referred toinifheie Letters Patent and making part of the seme.

To all persons to whom these presents 'may come Be it known that I, CHARLES H. SMITH, of Boston, in the county of Suffolk, and State of Massachusetts, have made a new and useful invention having reference to Ohurns and Butter-Workers; and I do herebydeclare the same to be fully described in the following speciiication, and represented in the accompanying drawings, of which- Figure l is ya side elevation, and Figure 2, averi/ical section of a churn andbntterworker made in accordance with my invention.

Figure 3 is a vertical section of the churn, it being taken through the fastenings by which the two parts ofthe barrel of the churn are connected.

Figure 4 is 'a top view of the churn-dasher. Figure 5 is a topvew of the butter-worker dasller. Figure 6 is a top view of' the cover of' the. butterworker. The tub` or reservoir of the churn is formed in two separate portions,'A B, one (A) of which rests directly on the top of the other (B,) or, in other words, onan annulus, O, of .India rubber, or other proper yielding substance, capable of making a tight joint between the parts when the upper one is drawn down upon suchV annulus.

A flange, a, projecting from the lower portion, B, encompasses the lower part of the upper portion, A, of the churn-reservoir.

The lower part, B, of the churn-reservoir is provided with a bottom, b, and rests directly upon a platform or stand, D, it being held thereon, and in connection with the upper part, A, by two screw-rods, E E, which ex tend upward from staples b b', inserted in the platform.

The rods go through ears, c c, extending from the lower part of the portion A of the churn-reservoinaud receive screw-nuts, d d, which, by being screwed down against the ears or 'washers f j, laid thereon, serve, with the rods and ears, to hold the parts A and B in connection.

There `are a cover, y, and a dasher, G, to the portion A, the rodof the dasher being extended through thel said cover. 4The-dasher is to be used 'for churning cream when in the churn.

Besides the churn -and its fastening, as described, there is vapplied-to the platform, by means of a lever, H, and a post, I, a butter-worker' dasher, K.

The post is jointed to the platform, so as to becapable' of being turned horizontally, and of being moved or vibrated both toward and awayfrom the churn.

The` said post at top is also hinged to oneend of the lever, such lever also being hinged to the top of the rod h of the butter-worker dasher K.

There is arranged concentrically on the rod 71., a cap or cover, L, which lits on the top of the lower part, B, ofthe churn, and is provided with a bar, i'. This bar extends diametrically across the said cover, and pr0- jects from it in opposite directions, in manner -as represented. At each of its-ends the bar is notched to receive one of the screw-rods E E, which, with their nuts, serve to fasten the cover tightly down upon the top ofthe part B. 4

The dasher-rod h, I usuallyv apply to the lever in a manner to enable the dasher K to freely revolve while being worked up and-down in the part B by the lever.

After the churn may have been used for the purpose of making butter, the buttermilk should be removed from it, and the upper part, A, and its dasher, s hould be removed from the lower port-ion, B.- N ext', the butter'- worker dasher should be introduced into the part B, and the cover L confined to the part B, by'means of the connection-rods and nuts and the cross-bar t.

By laying hold of the lever and pressing it downward, the dasher K will beforced down upon thefbutter, which, on being squeezed between the dasher and the bottomA of the tub or part B, will be tuscd to ow up through Y the openings of the dashcr, and up on its top. Next,

by drawing up the dasher, the butter may be pressed l, against the cover, so as to beagain squeezed through the dasher. These operations of the dasher being continued, will cause the buttermilk to `be expressed from the butter. Y

By having thechurn-rcselvoir inadcin two parts, A B, as described, and provided with means, as explained, for connecting them together, we are enabled to separate the upper portin from the lower, so as to admit ofthe latter being employed with the auxiliary cover and dasher, and its post and lever, as a butter- .worker, the churn-reservoir, whencoinposed ofthe two parts A B, being too large for such purpose.

I make no claim to a churn-reservoir consisting of a .single tub or vessel, B; but

I claim, as my invention, the following, viz:

The churn-reservoir, as composed of the two portions A B, and their fastening or connecting-devices, made and applied substantially as specilied.

Also, the combination of the auxiliary cover L and dasher K, and its operative lever H, or mechanism, with the platform D, or its equivalent, the two parts A B of the churn-reservoir, and the connection-de vices, substantially as described.
