CHURN.

SPECIFICATION forming part of Letters Patent No. 689,170, dated December 1'7, 1901.

Application filed June 8, 1901.

To all whom t may concern: Y

Be it known that we, JOHN W. DRAGoo and FRED SWALLoW,citizens of the United States, residing at Miami, in PeoriaNation, Indian Territory, haveinvented a new and useful Im-l provement in Churns, of which the following is a specification.

This invention relates generally to churns, and more particularly to that class thereof known as working-body churns, the object being to provide an exceedingly simple and efficient construction of churn in this class which can be quickly and easily manipulated.

Another object of the invention is to provide an improved construction for fastening the top to the said churn and alsoV connect- Fig. 2 is a sectional plan View.

In carrying out our invention We employ a base A, having uprights or standards B, pressed by means of suitable rods BC The standards or uprights are connected at their upper ends by means of a cross-piece C, and a crank-shaft E is journaled in the said'standards adjacent to their upper ends, said shaft carrying` a gear F at its outer end adapted to mesh with an internally-toothed wheel G, operated by means of the crank H. The crank portion of the "shaft E has a pitman I connected thereto, the lower end ofV said pitinan being connected to a cross-barl K, the ends of which fit into the ears or lugs L, fastened upon the upper edges of the churn-body M, said bar K serving to fasten the cover M upon the churn and at the same time connect said churn-body to the operating mechanism. The churn-body has laterally-projecting lugs N, which work in guideways N', produced in the standards B, thereby guiding the churnsenaiNo. 63,747. (No man.)

body in its reciprocation. .A helical spring O is fastened to the base directly beneath the churn-body, said spring being adapted to contact with the bottom of the churn-body upon the downward stroke, taking up the shock, partially supporting the weight of the churnbody, and assisting in its reverse or upward movement. Horizontal slots P are produced in the standards adjacent to the upper end of the guideways N', so that the churn-body can be removed at any time by disconnecting the bar K and elevating the body so as to bring the lugs N into alinement with the slots P, thus moving the body horizontally. All dashers are avoided, as the extremely rapid reciprocation of the churn-body thoroughly agitates and breaks up the cream, with the result of producing butter in an exceedingly short space of time.

' In order to prevent a too sudden upward thrustofthe springO,weemploysupplemental springs Q, which are attached at their lower ends to the base of the frame and at their upper ends are provided with hooks Q, which are adapted to engage the looped Wire R, said wire being bent to form a series of loops, so that a series of adjustments can be had.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a churn, the combination with base, and standards, of a crank-shaft journaled in the standards adjacent to their upper ends, means for rotating the said crank-shaft, the churn-body having guide-lugs at the side and working in guideways in the standards, a bar for fastening the cover of the churn-body, a pitman pivotally connecting the said bar and crank-shaft and a spring arranged upon the base beneath the churn-body, substantially as described.

2. In a churn the combination with a base having a spring arranged thereon, of the uprights mounted upon the said base, the crankshaft jou-rnaled inthe upper ends of the said standards, the gear-wheels operating the said shaft, the churn-body having perforated ears or lugs, the cover litted upon the churn-body and the cross-bar extending across the cover and engaging the perforated 1ngs,t.he guidesaid springs connecting the churn body and `lugs attached to the churn-body and Working base substantially as shown and described.
