CHURN.

SPECIFICATION forming part of Letters Patent No. 611,1 16, dated January 9, 1900.

Application iled September 19, 1899. Serial No. 730,975 (No model.)

T0 caf/ZZ whom t may concern:

Beit known that I, JOHN J. JONES, residing at Braman, in the county of Kay and Territory of Oklahoma, have made certain new and useful Improvements in Ohurns, of which the following is a specification.

My invention is an improvement in the class of working-body churns.

-I support the cream receptacle or body of my churn in a light frame hung from a crankshaft, which, being rotated, imparts a reciprocatory and oscillatory movement to said body, and thus quickly separates the butter from the other constituents of the cream.

, The construction, arrangement, and operation of parts are as hereinafter described, reference being had to accompanying drawings, in which* Figure 1 is a perspective view of my improved churn. Fig. 2 is a perspective View of the supporting frame or hanger for the churn-body. Fig. 3 is an enlarged vertical section of the upperyend of the churn-body and the metal frame lor spider employed for securing the cover thereon. Fig. I is a plan view of the supplemental base-support for the churn-body.

I employ a suitably-braced wooden frame for supporting the churn proper. A crankshaft 1 is arranged horizontally in suitable bearings on the top bars a of said frame and provided with a balance or fly wheel 2 at one end and a pinion 3 at thelother. A gears, mounted on a stub-shaft, meshes with the pinion 3 and is rotated by a hand-crank. It

is obvious that upon turning the latter the crank-shaft l will be rotated at a multiplied rate.

The metal frame or hanger 6 for supporting the churn-body or cream-receptacle 7 is hung from the crank-shaft 1, and therefore reciprocates and oscillates as the latter rotates. The side bars of said frame or hanger 6 are provided with hooks, by which it is suspended from the crank proper of shaft 1. These hooks are rigidly connected and braced and secured to the crank by means of a thick wooden bar 6a, (see Fig. 1,) to which they are bolted. The lower ends of the hanger-arms are bent laterally (see Fig. 2) and joined by a straight bar. A similar stirrup-like piece 6b is pivoted to the main porl .tion 6 of the hanger at the angles of its vertical arms. These stirrups furnish the basesupport of the churn-body 7, but I preferably employ a supplemental base 8, Fig. 4, which is arranged intermediately of the churnbody and hanger-stirrups 6 6b. It is a circular plate or disk constructed of any thin light material and provided with two sets of forked lugs 9 and 10, between which the hanger-stirrups 6 6b are held, as will be readily understood.

The upper end of the churn-body 7 is held in place in the hanger 6 and its cover 11 is secured tightly in place by one and the same means-namely, the conical skeleton frame or spider 12 and a crank-screw 13. The spider is composed of a circular rim 12a, having pendent lugs or flanges 12b, and several arms 12, that converge to a central block 12d, upon which the point of the screw 13 bears when the spider 12 is set in due position on the churn-body 7, as shown in Figs. 1 and 3. In such case the rim l2a of the spider rests upon the outer edge of the cover 11 and its lugs 12b fit over the edge, and thus hold said cover tightly in place. The screw 13 works vertically in a threaded bearing (see Fig. 1) attached to the brace-bar 6a, and its crank projects above that of the shaft 1, so that it may be freely rotated to secure or release the churn-body 7 as required.

To balance the weight of the crank and the parts suspended from it, I employ the liftingspring 15, which is attached at its lower end to a cross-bar b of the wooden frame A and its upper end connected by an S-shaped hook 16 with the crank proper of shaft 1. It is obvious that the spring 15 will be under increased tension when the crank swings down and will to that extent assist in raising the same in the next half of the revolution. As a further counterbalance the ily-wheel 2 is weighted at 17 on the side opposite .the crank of shaft l.

It is apparent that the rotation of the crankshaft 1 will cause the churn-body 7 to reciprocate endwise and also swing laterally. To limit such lateral movement, I provide a pivoted and jointed stay consisting of a rod 18, Fig. 1, hinged to an adjacent cross-brace c of frame A, and a bifurcated or V- shaped piece or loop 19, which is attached to the inner end IOC of said rod and also to the hanger-stirrup, from which it is pendent. This stay will obviously follow the movements of the churnbody 7 without permitting other than a slight lateral play of the same. The loop 19 may be constructed of strap-steel, so as to have sufficient elasticity to permit the hanger-stirrups to be brought nearer each other or spread farther apart, according to any Variation that may be preferred in the distance between the lugs 9 and 10 of the base 8.

It is apparent that the churnbody With the spider 12 may be quickly set and secured in the hanger 6 upon .the base 8 or removed therefrom by adjusting the crankscrew 13, so as to bear upon and clamp or release the spider.

In practice the churn-body is provided with lateral handles for convenience in handling.

What I claim is- The combination Withthe supporting-frame and horizontal crankshaft thereon, of a hanger for the churn-body Which is suspended from the crank, a brace-bar arranged below the crank, a screw-nut attached thereto, a screw Working vertically therein, and a device which is applicable to the churn-body for clamping it in place, substantially as shown and described.
