WILLIAM D. HAMMOND, OF BUSINESSBURG, OHIO.

CHU-RN.

SPECIFICATION forming part of Letters Patent No. 516,970, dated March 20, 1894.

' Application filed April 7, 1893. Serial No. 469,422. (No model.)

To wZZ whom it may concern.-

Be it known that 1, WILLIAM D. HAMMOND, a citizen of the United States, residing at Businessburg, in the county of Belmont and State of Ohio, have invented a new and useful Improvement in Ohurns, of which the following is a specification.

The invention relates to improvements in churns.

The object of the present invention is to improve the construction of churns, to increase their efficiency and to enable butter to be rapidly produced, and to cause the butter to collect in a roll to facilitate its separation and removal.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figure 1 is a perspective view of a churn embodying the invention. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is a transverse sectional view. Fig. 4 is a detail perspective view of the dasher cylinder, the detachable peripheral plate being removed. Fig. 5 is a similar view of the detachable peripheral plate.

Like numerals of reference indicate corresponding parts in all the figures of the drawings. V

1 designates a churn body having a curved bottom 2 and provided at its corners with legs 3 and 4. The legs 4: are provided at their lower ends with sockets 5 and have secured within them upturned ends 6 of a horizontal spindle 7, which has mounted on it wheels or rollers 8. The rollers 8 are separated and retained at the ends of the churn body by a sleeve 9, which is arranged on the shaft and disposed between the rollers 8. By having the two legs 3, which rest directly upon a floor or supporting surface, and the other leg 4, which are provided with rollers, the churn body is supported in a steady mannerduring operation, and maybe readily moved from one place to another on the rollers 8. I

Within the churn body is mounted on j ournals 10 and 11 a revolving dasher cylinder 12, which is composed of end disks 13 and a series of substantially tangentially disposed the butter collects in the inside of the dasher I cylinder, but some collects in large lumps outside, the lumps of butter being too large to readily pass through the peripheral openings between the plates. This outside butter may be readily pushed through the spaces between the plates into the dasher cylinder, after which a few rotations of the cylinder'will cause the loose butter to collect in a roll. The

butter is removed from the cylinder through an opening formed by the removal of a detachable peripheral plate 16, which is provided at the inner ends of its securing flanges with notches 17 for engaging projections 18 on the inner faces of the end disks 13. The removable peripheral plate is retained in position by a spring 19 arranged on the outer face of one of the disks 13 and having one end secured to the same, and its other end 20 bent at an angle and arranged in a perforation of the disk and engaging a perforation 21 of the adjacent flange of the removable peripheral plate.

On the ends of the dasher cylinder are fastened

bearing plates

22 and 23; the bearing plate 22 has acentral concavity for receiving the journal 10 5 and the other bearing plate 23 has a central rectangular opening, which receives a squared end 24 of the journal 11. The journal 10 has a threaded shank 25 to enable it to be adj usted; and the outer end of the shank terminates in a thumb piece; and a jam nut 26 is arranged on the threaded shank to limit the inward movement of the journal. The journal 11 is provided adjacent to its squared end with an annular flange to form a tight joint to prevent the escape of the liquid contents of the body through the opening for the journal; and the latter has a threaded stem 28 on which is secured a crank handle 29. The annular flange 27 is held in close contact with the inner face of the adjacent end of the body by a fiat spring 30, secured to the body and arranged on the exterior of the same and disposed above thejournal l1 and having its lower end extended outward and provided with a notch and engaging the opening end of the bar of the crank handle to force the journal outward. The ends of the body are provided with projecting handles; and the cover 31 has a central perforation over which is arranged a vertical vent tube 32 formed integral with a securing late 33.

It will be seen that the churn is simple and comparatively inexpensive in construction, that it is eflicient in operation and effects a rapid production of butter, and that the butter may be collected in a roll and readily removed. The dasher cylinder is removable from the body by means of the journals, and after the operation of churning has been completed it is taken from the body, and the butter within it may be readily removed by means of the detachable peripheral plate. provided at its upper edges with projecting angle flanges 3% arranged at the corners to 'receive the corners of the cover, which is recessed to form shoulders 35 to prevent displacement. These angle flanges 34 are formed by the legs of the .body 1; and the legs consist of angle irons and project above the upper edges of the body and are arranged in the recesses of the cover.

Changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

The cylinder is of great ad vantage in holding the butter while the buttermilk is drawn off, and it enables the butter to be readily and The body is,

conveniently Washed with cold water or treated with salt water.

What I claim is 1. In a churn, the combination of a body and a rotating butter collecting dasher mounted within the body and comprising ends and a series of substantially tangentially disposed peripheral plates connecting the ends and forming an interior chamber, one of the plates being removable to afford access to the chamber, substantially as and for the purpose described.

2. In a churn, the combination of a body, and a rotating dasher cylinder, composed of circular ends and peripheral plates provided at their ends with securing flanges, one of the plates being detachable and provided in its flanges with notches, projections arranged on the inner faces of the ends and engaging the notches, and a spring having one end bent at an angle and extending through the adjacent end piece and engaging the detachable plate, substantially as described.

3. In a churn, the combination of a body,

the journals mounted in the body and having threaded shanks, one of the journals being loosely mounted and having its inner end squared and provided with a flange, and the other journal engaging a threaded opening of the body a rotating dasher cylinder mounted on the journal and having a square opening at one end to receive the squared journal, a crank handle attached to the loosely mounted journal, and a spring secured at one end to the body and having its other end engaging the crank handle, substantially as described. In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
