IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. l March To all whom 'it may concern.'

Beit known that I, GEORGE RIDLER, of Jefferson township, in the county of Dubuque and State of Iowa, have invented a new and valuable Improvement in Churning Apparatus; and Ido 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 to the letters and figures of reference marke thereon.

Figure l of the drawings is a representation of a longitudinal vertical section of my churn, and Fig. 2 is a transverse vertical sectional view of the same.

The nature of my invention consists in the construction and arrangement of a churn, as will be hereinafter more fully set forth.

In the annexed drawing, A represents the box, of any suitable dimensions, provided with a stationaryv center dash, B, placed trans- Versely in the churn-box. This dash is perforated and slotted, as shown, and supports the cross-bar C, and the cream being thrown against said dash causes the globules to break.l In the cross-barC isinserted a double screw-axis, D, upon which .the rocking dasher works. This dasher consists of a horizontal lever, E, pivoted on the axis D, and having at one end two parallel V-shaped cross-bars, G G, set at right angles to said lever, and at the other end a perforated and beveled dash, G. The dasher thus constructed, by its rocking motion, causes a rebound action on or in the crea-1n, making it dash from one side of c the churn to the other, sending it through the slots and holes of the center dash B, and preventing the dashing of the cream up against the top of the churn. The center dash B and cross-bar C are held in place by two sliding bolts, a a. H is the lidot' the churn, with apertureb, through which the rod I passes to c connect the rocking4 dash with the lever K.

0n the under side ofthe lid is a sliding ventilator, J, through which said rod I also passes. This ventilator prevents the cream from coinlng to the top of the lid, and it has raised edges d d, so as to make 'a space under the lid, through which air from the exterior is admitted to the churn, its admission being facili tated by the vibrating motion given the slide J by the lever I. The lever K is pivoted in' ISO,640, dated August 1, 1816; application filed 4, 1876.'

the top of a' standard, M, and under its inner en-d is a spiral spring, f, with rubber cushion e acting as a push-spring. Under the-outer end ofthe lever is a double-bow draw-spring, h, with a spiral push-spring, fi. These springs help to work the lever and to regulate the stroke ot' the dash when churning with the lever K. The standard M is fastened to the end of the churn by means of a staple, c, a hook-bolt, m, and a hut, a, as shown.

For churning with a power attachment the outer end ofthe lever K is, by a pitman, N, connected with a wrist-pin, p, on the wheel O, the pitman-connection to said pin being adjustable, so as to move the pitman back and forth for regulating the stroke of the dash when' churning.

The churn A may be surrounded by a chamber to contain hot or cold water for regulating `the temperature of the cream.

What I claim as new, and desire to se'ure by Letters Patent, is

l. The oscillating dasher, consisting ofthe lever E, V-shapcd bars G G, ainhbeveled and perforatedbar G', combined with and rocking upon the screw-axis D, located centrally pose set forth.

2. The combination of the stationary dash B, carrying the cross-bar C, with its screw D D and keys a a, and the Vrocking dasher E, carrying V-suaped bars G and beveled' perforated dash G', the whole being operatedby the verteally-reciprocatiug rod I, substantially as described. y

3. In combination with the 'vibrating rod I the correspondingly-vibrating ventilator. J, having beveled edges d operating under the cover, and serving to prevent splashing and to secure ventilation, as set forth.

, 4. In combination wit-l1 the lever K and its fulcrum M, the spiral spring f, with rubber cushion e, and the draw-spring h, passing through the whole being mounted upon the said fulerum M, as shown, for thel purpose `set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses. I y

GEORGE RIDLER.
