AMERIOUS VESPUCIUS COOK, or DEXTER, MISSOURI.

'CHURN.

SPECIFICATION forming part of Letters Patent No. 363,450, dated May 24, 1887.

Application filed March 12, 1287.

To aZZ whom it may concern.-

Beit known that I, AMERIOUS VEsPUoIUs 000K, a citizen of the United States, residing at Dexter, in the-county of Stoddard and State of Missouri, have invented a new and useful Improvement in Ohurns, of which the following is a specification.

My invention relates to improvements in churns, the objects being to lessen the labor of churning and cleaning the churn, to lengthen or shorten the stroke of the dasher-rod when desirable, and to provide a churn of simple and durable construction. These objects I attain by means of the construction and novel arrangement of parts hereinafter described, embraced in the appended claims, and illustrated in the accompanying drawings, in which Figure 1 represents a perspective view of the improved churn, seen from" the side 011 which the churn barrel or cylinder is placed. Fig. 2 is a side elevation of the same. Fig. 3 is a detail sectional view showing the connection of thepitman, cross-head, dasher-rod, and nut. Fig. 4 is'a perspective view of the long connecting-bolt detached. Fig. 5 is asectional H view showing the cross-head.

Referring to the accompanying drawings by letter, A designates the base-plate of the main frame, and B is the upper plate of the same.

b b are upri hts, which connect the side edges of the base-plate near one end with the lower surface of the upper plate, B, near its side edges.

O is a verticalbar, which stands from the end of the base-plate adjacent to the uprights b b, is secured to the edge of the upper plate,

'B, and extends above said plate to a suitable ion, E, on a shaft, 6, journaled in bearings on the same edges of the said bars or uprights above the wheel D; The wheeland pinion are situated between the uprights, and the shaft Serial No. 230,694. (No model.)

d is extended outward from its exterior bearing and squared to engage a crank-.handle, d, which gives motion when rotated to the mechanism. Secured to the inwardly-extended end of shaft 6 is the disk F, provided with a radial series of adjusting-openings,ff.

Gris a pitman, the upper enlarged end of which may be attached to the disk by a screw or pin, 9, passing through an opening in said end, and engaging in any one of the openings f. The lower end,' q, of the pitman is alsoenlarged andprovided with an opening,through which it is connected to the cross-head H bya long bolt, h.

. The cross-head H is rectangular in shape, and provided in its ends with the notches h h, which lit and slide upon theinner correspond.- ing edges of the vertical bars *6 i of the guide frame I, standing from the upper plate, B, a suitable distance in front of the bar 0.

K is the dasher, of any suitable size, shape, and construction; and-Iris the dasher-rod rising centrally therefrom, and provided with the se ries of adj Listing-openings k. The bolt h, after passing through a central transverse opening in the cross-head, passes through any desired one of the openings 7c, the stem of the bolt being reduced in size and having its threads removed at k, where it rests in said opening, and for a short distance on each side of the dasher-rod.

L is an elongated nut having its inner or On account of the adj ustingopenings is being extended laterally and the stem of the screw being reduced where it passes through one of said openings, the nut L, when not screwed up against the dasher-rod, will, while preventing said rod from being displaced, allow it and the attached dasher to swing freely in all directions within the churn barrel or cylinder M, placed below on the base-plate A, a

KOO.

Thelateral adj ustingfopenings 7c of the dasher-rod are of such a diameter that the threaded portion of the bolt h will pass readily therethrough, and consequently when the rod is hung on the reduced portion of said bolt it will 15 f and screw or pin 9 the stroke of the pitman can be changed. 7

In operation, the motion of the handle d is communicated to the disk F through the wheel D and pinion E. The rotation of the disk 1:" reciprocates the pitman G, and simultaneously operates the cross-head Hand the dasher-rod, as will be readily understood.

Having described my invention, I clai1n- 1. In a churn, the combination of the dasher, the dasher-rod provided with a longitudinal series of lateral adjusting-openings, the pitman, the eross-head reciprocating in a guidefraine attached to the main frame, and the bolt connecting the lower end of the pitman, the crosshead, and the dusher-rod together, re-

duced in diameter, and having no threads at and on each side of the portion resting in one of the adjusting-openings in the dasher-rod, and engaging a suitable nut to retain the latter in place, substantially as described.

2. In achurn, the combination of the dasher, the dasher-rod 70, provided with the lateral openings 75 and the vertical concave portions Z, and the plate B, having the guide-notch l on its edge, of the nut L, having the convex bindingsurface l, the screw-bolt h, having the reduced and unthreaded part 70, the crosshead, the pitman G, and mechanism, substantially as described, whereby said pitman is actuated, substantially as specified.

3. In a churn, the combination of the dasher, dasher rod having lateral adjusting-openings, the bolt having a reduced unthreaded part to enter one of said openings, and the reciprocating crosshead, with the pitman, the disk F, provided with the adjusting-openings), to any one of which the upper end of the pitman may be engaged by a screw or pin, 9, and means, substantially as described, whereby said disk is rotated, substantially as specified.

In testimony that Iclaim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

AMERIOUS VESPUOIUS COOK.
