CHURN.

QPECEFEOATION forming part of Letters Patent No. 334,720, dated January 19, 1886.

Application filed April 28, 1885. Serial No. 163,727. (No model.)

To all whom it may concern:

Be it known that I, J OHN WILLIAM PER- soHN, a citizen of the United States, residing at McKinney, in the county of Collin and State of Texas, have invented certain new and useful Improvements in Ohurns; and I do hereby declare 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, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to churns; and it consists in the improvements hereinafter set forth, whereby a simple and effective device is provided that may be applied to and used in connection with any existing churn-body; and in which its action may be either single or double acting by means of a simple and efficacious arrangement of parts.

' In the accompanying drawings, forming part of this specification, Figure 1 is a perspective view illustrating my improvement applied to an ordinary churn-body, a portion of the latter being removed to more clearly show the double dasher. Fig. 2 is an enlarged elevation of the improvement, representing the device adapted to actuate the dashers with a single-acting effect; and Fig. 3 is asectional view of the parts that engage the dashershanks.

The improvement is supported with reference to the tub or body by means of a vertical bar, A, the lower portion, a, of which is bladed and tapered, as represented in Fig. 1, in order that the same may snugly enter a metallic socket, I), attached to the side of said tub or. receptacle. A horizontal arm, B, is adjustably secured to the bar A, at its upper end, by means of a thumbscrew, a, or other locking device, to accommodate different sizes of churns. The end of said arm B carries a vertical portion, 0, from the upper and lower end of which extend horizontally circular bearings d e, the upper bearing being much smaller than the lower one. Centrally and horizontally from the vertical portion 0 extends a bearing-arm, D, which is provided with a transverse perforation. A vertical shaft, E, has its upper end supported in the upper bearing, d, and projecting beyond the same,

so as to receive a gear-pinion, f. The said vertical shaft E, after extending downward and passing through the bearing 6, terminates in an enlarged socket, g, which is provided with a square vertical recess, and has one side cut away.

F represents a vertically-elongated sleeve, which embraces the lower portion of the vertical shaft E. The said sleeve F terminates at its upper end in an annular collar, h, a short distance below which is located a gear-pinion, G. The lower portion of said sleeve F is enlarged and provided with a square vertical recess. A stud or stub-shaft, i, is secured in the end of the arm D, and on said shaft 2' is mounted a gear or drive wheel, H, the side face of which is provided with an annular series of gear-teeth, j. This said wheel H is provided with a peripheral groove, 70, for the application of a driving-belt, or may be rotated by means of a handle, 1. Two dashers are employed independent of each other and located one within the other, as represented in the accompanying drawings. I refers to the inner dasher, the dasher portion of which consists of a flat-bladed portion provided centrally with a vertical opening, and having a lug or projection, m, projecting centrally from its lower edge. This said lug is designed to rest in a depression therefor formed in the bottom of the tub. A metallic shank, n, is recessed to receive the upper portion of said dasher, and terminates at its upper extremity in a square-ended portion, 0, of such size as to permit it to be readily inserted in the socket of the shaft E, through the opening in the side of the same, and when in said socket fit sufficiently snug therein to enable said shaft E to rotate with said shank; or the shaft E may be provided with a clutch-couplin g to receive the end of the shank n and make a fast connection therewith, so that the dasher I can be supported thereby independent of the tub.

The outer dasher consists of a horizontal metallic bar, K, from each end of which depends a dasher-blade, p. A vertical sleeve, L, is formed integral with said bar K, and is square ended at its upper extremity.

M refers to a bell-crank lever, which is pivoted at its elbow on the side of the vertical portion of the arm B, and has its upper portion bent horizontally and at right angles with the bell-crank lever to form a handle, q. The lower end portion, 8, of said bell-crank lever is bent inwardly toward the sleeve F, so as to enter the annular space between the collar h and gear-pinion G.

From the foregoing it will be apparent that when the bell-crank lever M is operated to vertically shift the sleeve F it disengages the gear-pinion G from engagement with the annular series of teeth j on the side of the drivewheel H. Now, by revolving said drive-wheel the central shaft, E, only will be revolved, such revolving movement being imparted to its dasher, the motion of which will cause the outer dasher to revolve in the same direction with it and the liquid in the churn. When the sleeve F is forced downward, to cause the pinion G to re-engage the teeth j, its lower enlarged and recessed portion slides over the square end of the sleeve L. The revolution of the drive-wheel H will now cause the central shaft, E, to be revolved in one direction, while the pinion G will effect the revolution of the outer dasher in a contrary direction, the dashers being thus revolved in opposite directions. By employing a socket for the shaft E having one side removed, the upper end of the shank of the inner dasher may be readily removed laterally from the same and both dashers lifted out of position without disturbing the relative positions of the driving devices.

I am aware that churns have been made with revolving dashers, and with mechanism for operating them, and that the operating mechanism has been carried by adjustable arms engaging with vertical bars attached to the sides of the churns. I therefore do not claim any of these things, broadly.

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

In a churn, the combination of the vertical shaft E, provided with a pinion and a socket having a square recess in it, the dasher I, provided with a square-ended shank, the sleeve F, provided with a pinion, a square recess, and the collar h, the dasher-bar K, having a vertical square-ended sleeve integral therewith, the drive-wheel H, the lever M, the bar g A, and the adjustable arm B, provided with bearings for the said shaft and sleeve, and a pin for the said lever, substantially as and for the purpose set forth.

In testimony whereof I afliX my signaturein presence of two witnesses.
