CHURN.

sPEcIFIcATIoN formingpa'rt 'of Letters Patent No. 532,644, dated. January 15,1895.

Application tiled August 9, 1894. Serial No. 519,868. (No model.)

To @ZZ whom it may concern.-

Be it known that I, WILLIAM H. OURTIGE, of Eminence, in the county of Henry and State of Kentucky, have invented certain new and useful Improvements in Churns; and I do herebydeclare the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art .to which it appertains to make and use the same.

My invention'relates to an improvement in churns, preferably of the class known as swinging churns, and `it,consists in certain novel features of construction and combinations of parts as will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings, Figure l is a view of my improvement in side elevation,

showing the screen or strainer in dotted lines.

Fig. 2 is a vertical transverse section of the same, showing the screen or strainer in its operative position. Fig. 3 isa view showing the manner of attaching the handle to one of the swinging arms or rods; and Figs. 4 and 5 are detached views of the supporting bracket and screen or strainer, respectively.,

A represents the churn body; ct, a, the hoops thereof; 6,19, the adjusting wedges, and c, c, the supporting brackets, which latter are each provided with an oblong slot d, within which moves the screws or pins e carried by the adjusting wedges b, b. The upper face of the adjusting wedges b, b, rest against the bottom of churn A, while their lower faces rest against the inner faces of hoops a, ct.

The churn bod y A is held together by means of the hoops a, a, which 'latter are tightened and retained in their normal position by the wedges b, b, said wedges being so constructed and arranged that they can be forced apart in order to tighten the hoops a, a, without interferingwith any of the other parts of the churn or its attachments, the Wedges being retained against displacement by the screws or pins e, which latter when the wedges are moved in either direction are adapted to travel in the oblong slots or grooves d, and hence any tendency on the part of the wedges to depart from their course is obviated.

The supporting brackets c, c, are each provided on their lower ends with an open slot f, the inner portion of which latter constituting a bearing g, while the forwarld portion thereof is of greater diameter than said bearing g, whereby a recess his formed for the reception of keys t', the latter being retained against sidewise movement by the shoulders k, k at the inner and outer ends of slots f.

The body portion of churn A is provided in its top with an opening f and this is closed by the removable lid Gr.

The supporting frame B ot' the churn is preferably constructed of pipe or tubing and of the form shown in` the drawings. To the frame B are pivotally connected the swinging arms or rods C, C', which are substantially U -shaped and extend from one side of frame B to the opposite side thereof. The swinging arms or rods C, C', are loosely mounted in bearings g, located insupporting brackets c, c, which latter are secured to the sides of churn A in any desired manner, and hence it will be seen that the latter is movabl y supported on the frame B.

The outer or pivotal end of swinging arm or rod C is so arranged as to constitute the pivotal point and connection for handle D, which latter is also rigidly secured to said arm or rod C yat the point e', by means ot' the fastening m, and hence it will be noticed that when handle D is moved, arm or rod C is necessarily moved. Consequently the churn body is vibrated. At or near the lower end of handle D is located a hole or opening n, which is in open communication with both sides thereof, and is adapted to register with a like opening o passing through the collarp of treadle E. When the collar of treadle E is slipped over the end of handle D, the holes n, o, are adapted to register so as to receive the spring key fr, by means of which the treadle E is removably secured to the handle D.

When the churning has been completed, the Wire screen or strainer F is placed within the churn body A as shown in the drawings. This wire screen or strainer F, consists of a frame s, wire netting or fabric connected to said frame and a handle t, by means of which the screen or strainer is manipulated and held in position with the churn. In order to make the screen or strainer have a nished appearance at the juncture of frame s and wire fabric s', a series of narrow metal strips u are soldered around frame s and fabric s', VVwhich not only accomplishes the result above noted,

but prevents the wire fabric from becoming loose or detached and further renders the entire device stronger. The `wire screen or strainer is preferably bent substantially in the arc of a circle and when placed in the position disclosed in the drawings, is prevented from being displaced by the handle t, which latter abuts against one end of opening f in the top of churn A.

When it is desired to draw off the milk, the churn is first tilted in the desired direction, which causes the butter and milk to assemble in the lower end of the churn. The wire screen or strainer is then inserted, after which the churn is tilted in the opposite direction, which causes the milk to pass through the wire fabric s', and out of the opening zu, located in said tilted end of churn, the butter being caught by the screen. After the milk has been drained off, the butter can be removed by simply removing the screen or strainer F.

It is evident that changes in the construetion and relative arrangement of the several parts might be made without avoiding my invention and hence I would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described, but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a churn, the combination with a churn body, of hoops around the body and secured together at the ends, wedges inserted between the body and the hoops and adapted to be forced apart to tighten the hoops, brackets secured to the churn body, screws passed through the brackets into the wedges whereby to hold them in place, substantially as set forth.

2. In achurn, the combination with a frame, a churn body, and hangers hinged tothe frame and supporting the churn to swing back and forth, of brackets having bearings therein to receive the hangers, keys in said brackets to retain the hangers in the bearings, hoops around the body, said hoops having their ends secured together, Wedges interposed between the body and hoops, and screws passed through elongated slots in the brackets into the wedges whereby to hold said wedges in position when adjusted, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
