CHURN-DASHER.

SPECIFICATION forming part of Letters Patent No. 363,231, dated May 1'7, 1887.

Application filed March 19, 1887. Serial No. 231,476. (NomodeL) To all whom it may concern:

Be it known that I, SI-IELTON CITIZEN HAR R1soN,a citizen of the United States,and a resident of Rocky Mount, in the county of Frank lin and State of Virginia, have invented certain new and useful Improvements in Ohurn- Dashers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure l is a vertical sectional view of a churn, showing my improved dasher in side view, and Fig.2 is a vertical sectional view of the same.

Similar numerals of reference indicate corresponding parts in both the figures.

My invention has relation to that class of churn-dashers in which eross-pieces are piv otally attached to vertically reciprocating dasher-staffs, so that the said cross-pieces may be rocked when the staffs are reciprocated, thus churning the milk or cream in the churn and it consists in the improved construction and combination of parts of such a dasher, as hereinafter more fully described and claimed.

In the accompanying drawings, the numeral 1 indicates the churn-body,which is provided with the removable lid or cover 2, having a rectangular central perforation, 3, which registers with two smaller rectangular pcrforations, 4, in the center of a cross-piece, 5, or top piece of an upright frame, 6, secured upon theupper side of the cover.

The dasher-staffs 7 slide and fit with their upper portions in the perforation in the con ter of the lid or cover, and the upper ends, 8, of the dasher-staffs are reduced upon their meeting faces and slide in the perforations in the top piece of the upright frame, a space being formed between the said reduced ends.

A bolt, 9, passes through the upper portions of the side pieces of the upright frame and into the space between the reduced upper ends of the staffs, and the central apertured portion, 10, of the operating-lever 11 is pivoted upon this bolt, the side pieces, 12, of the frame formed at the apertured middle of the lever, having the bolt passing through them. The

lever has two plates, 13, secured upon the un der side of its arms a short distance from the dasher-staffs, and the lower faces of these plates are formed with perforated cars 14, be-

tween which the upper perforated ends of two arms, 15, are pivoted upon bolts 16. Thelower ends, 17, of these arms are bent inward and formed with lips l8,which straddle the dasherstaffs and are pivoted by means of pins or bolts 19, passing through the lips and staffs; and it will be seen that as the lever is rocked the (flasher-staffs are alternately raised and depressed bythe arms being drawn upward and depressed by the arms of the lever.

The lower portions of the dasher-staffs have registering pairs of transverse pins 20, and disks or cross-plates 21 have rectangular apertures at their mi'ddles, with which they are slipped upon the staffs, and are retained upon the staffs by means of the pins, one pair of pins confining each disk or plate from above and one pair from below, the disk or plate, however, having free play between them. It will now be seen that as the dasher-staffs are reciprocated the ends of the disks or plates are alternately depressed and raised,the rocking disks or plates thus churning the milk or cream when the dasher is placed within a churn and the lever is rocked.

By rocking the lever comparatively slightly, and thus reciprocating the dasher-staffs merely a short space, the cross-pieces may be rocked considerably,as the transverse pins engage the apertured centers of the said disks or crossplates near the centers of them.

Having thus described my invention, Iclaim and desire to secure by Letters Patent of the United States 1. In a churn-dasher, the combination of two reciprocating dasher-staffs having means for reciprocating them, and having pairs of registering transverse pins inserted through them, with disks or cross-plates having apertures in their centers and fitting with the said apertures upon the staffs between the pairs of transverse pins, as and for the purpose shown and set forth.

2. In a churn-dasher, the combination of a cover for the churn, having a rectangular aperture and having an upright frame formed with two apertures in its top piece registering with the rectangular aperture, two dasherstaffs sliding in the aperture in the lid or cover and having their upper portions reduced upon the inner meeting faces, a lever having its middle formed into a frame and having a bolt passing through the side pieces of the upright frame and of the frame of the lever and in the space between the reduced ends of the staffs, arms pivoted between perforated lips upon the under sides of the arms of the lever and having their inwardly-bent ends formed with apertures and fitting loosely with thesaid apertu res upon the staffs, having registering pairs 1 5 my own invention I have hereunto affixedmy 2o signature in presence of two witnesses.
