ISAAC L. smenn, on NEW YORK, N. Y.

CHURN.

SPECIFICATION forming part of Letters Patent No, 361,458, dated April 19, 1887.

Application filed January 1887. Serial No. 223,645. (No model.) I

To all whom, it may concern.-

Be it known that I, ISAAC L. SINGER, of the city, county, and State of New York, have invented certain new and useful Improvements in Churns, of which the following is a specification.

This invention relates to'certain new and useful improvements in rocking churns; and the object of my invention is to provide a churn in which butter is produced very rapidly without any waste of power.

The invention consists of the construction and combination of parts and details, as will be fully described and set forth hereinafter, and finally pointed out in'the claim.

In the accompanying drawings, Figure 1 is a sectional plan view of my improved churn. Fig. 2 is a side view and partial longitudinal elevation of the same. Figs. 3 and 4 are side views of two racks and pinions. Fig. 5 is a face view of one of the dashers-in the creambox. Fig. 6 is a horizontal sectional view of the same.

Similar letters of reference indicate corresponding parts.

The cream-box A, having the hinged covers B, is provided with legs 0, fastened on rockers D, mounted to rock on a base, E, at each side of which a standard, F, is provided. At the upper end of each standard a slotted frame, G, is secured, one of which frames is provided with a rack, G, in the bottom edge of the slot, and the otherwith a rack, G, on the top edge of the slot. With said racks the pinions I 1 engage, which are mounted on the opposite ends of shafts H H which are mounted in suitable journals in the sides of the cream-box, and at their inner ends are journaled on a bar, T, in the box. On each shaft-a rotary dasher, K K is mounted within the cream-box, said rotary dashers consisting of blades held between two circular pieces fastened by spokes on the A semicircular top part, L, is provided on the top of the cream-box above the rotary dashers K K and has a hinged coversection, L.

At each side of the rotary dashers a transverse detachable dasher-plate,M,is provided in the cream-box, saiddasher-plates being provided with tapered apertures N, which are alternately tapered in opposite directions. Two arms, 0, project from each end of the cream-box A, and are united by a handlerod, P.

A plug, Q, closes an aperture in the bottom of the cream-box for turning off'the butlermilk.

The operation is as follows: The cream-box is rocked in the usual manner, and as the pin ions H H engage with the racks in the top and bottom of the slots G and G, respectively, it is evident that the two rotary dashers are at all times reciprocated in opposite directions.

The cream is also dashed through apertures in the dasher-plate M and thrown forward and The cream-box and the several parts can he cleaned very rapidly, and the entire churn is a very simple construction.

Having thus described my inventioml claim as new and desire to secure by Letters Patent- The combination,with a rocking cream-box, of two transverse shafts journaled in the same in line, a rotary dasher'mounted on each shaft, and a pinion on the outer end of each shaft, and fixed slotted frames at the sides of the box, and having racks engaging with the pinions, of which racks one is formed on the bottom edge of the slot in the frame and the other on the top edge of the slot in the frame,whereby the rotary dashers are'reciprocated rotatively in opposite directions while the boxis being rocked, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

ISAAC L. SINGER.
