Specification of Letters Patent No. 25,558, dated'September 27, 1859.

To all whom it'may concern:

Be it known that I, ABEL AUSTIN, of Al tona, in the county of Knox, in the State of Illinois, have invented a new and useful Improvement in Churns; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and in which igure 1 represents a perspective View of the machine, Figs. 2 and 3 represent end views, with the dashers and cranks in reversed positions, Fig. 4 represents a side view, Fig. 5 the churn lid.

To enable others skilled in the art to make and use my invention, I will proceed to describe and explain its construction and operation.

The churn box may be made square and nailed or screwed together or by inclining the sides, see Figs. 2 and 3 to make it smaller at one end it may be hooped perfectly tight see Fig. 1; the ends of the box must in all cases be parallel see Fig. 4: to allow the middle dasher D which fits snugly between them a free motion up and down.

The shaft a is made with three cranks a, a, a, see Fig. 1, to operate the dashers D,

see Figs. 2 and 3. The middle crank (4 Figs. 1 and 2 stands at right angles to the two side cranks a, a, and the cranks a, a, stand on opposite sides of the shaft (1. see Fig. 1.

The connecting links 6, 6, Z), are attached to the handles D, e, e, of the dashers D, E, E, to connect them with the cranks on the shaft a and are each provided with a spring C Figs. 1 and 2 for the purpose of easily attaching and detaching them from the cranks a, a a.

The box 2' 2' Figs. 1 and 2 of the shaft a is hinged so the top can be opened upward, when the spring 9, which fastens it down is pushed back, by this arrangement the shaft a can be easily and quickly put in place or removed.

N, N, Figs. 2,

3, and 4, are stays or guides on the ends of the churn box to keep the The lid F, F, Fig. 5, is made in two parts, F part is made with two pivots H, H, in it for the side dashers to work on as in Figs. 1 and 4 the slot P, for the handle of the middle dasher to work in see Figs. 1 and 4.

The button K is both parts of the Th Milk is poured into. the churn, Fig. 1, F part of the lid is turned enough to fasten it, the shaft a is then turned giving motion to the cranks a, a, a, which operate the dashers in this manner, when the middle crank a is upward as in Figs. 1 and 2 the middle dasher D attached to it is in the position shown in Fig. 2 and the side dashers E, E operated by the cranks a, a, are in the position represented in the same figure, when the shaft a designed to fasten, one or lid.

is turned half of a revolution see Fig. 3

the cranks a, a, a, Fig. 3 are in a reversed position from Fig. 2 and the dashers attached to them are also in reversed positions the revolution of the shaft a consequently giving an upward and downward stroke to the middle dasher D and a lateral stroke to the side dashers E, E, at the same time, for as the middle dasher D is going up the side dashers E, E, are coming together in the center of the churn see Fig. 3 and When the middle dasher D is moving down the side dashers are separating see Fig. 2.

The half lid F can be removed at pleasure while churning. When done the button K can be'turned so as to unfasten the lid entirely and by pressing the spring g, back which fastens the upper part of box 71 down and keeps the shaft a in place the shaft can be drawn out of the churn with the dashers and half lid F attached thus leaving the churn box entirely clear. The milk may then be poured off from the butter, the middle dasher D unhooked from the crank a by pressing the crank against the spring 0 and slipping it out from the link, the shaft with the two side dashers and half lid F may then be put back into the churn, the shaft a slipped into the boxes and refastened by shutting down the upper leaf of the box 2', until spring 9, holds it, water can then be poured into the churn and the butter principally worked over, and the buttermilk pressed out with the side dashers E E, by

turning the shaft a which operates them as 105 in churning.

This churn can be very easily and cheaply constructed, the crank shaft, dashers, and box being all simple and easy to make and at but small expense for labor and material.

The most effective motion for churning e operation of the machine is as follows milk appears to be a breaking or dashing they are also designed to gather the butter motion which has the effect of breaking the after it is churned and press and work out globules of cream which compose butter so the buttermilk.

they will adhere together. For this reason d down dasher a, a, a, and dashers D, E, E, with hanthe old principle of the up an I disclaim the shaft a with the cranks has been established by long experience to dles D, e, e.

be as good as any in use and although many rotatry dashers give a greater motlon or Ve- I claim- The arrangement of the shaft 11,, cranks locity to the milk butbeing in one direction a, a, a, dasherss D, E, E, handles D, e, 6, it does not appear to be any more effective links I), b, b, springs c, c, 0, box 21, i, spring g, and frequently not as effective in churning and lid F F together, the same being conas the old method.

My invention uses the old principle of the tially as and for the purpose specified.

up and down dasher and for the purpose the great-est possible effective motion to the milk in a breaking or dashing manner, the side dashers having a lateral stroke are added,
