CHURN.

SPECIFICATION forming part of Letters Patent No. 634,408, dated October 3, 1899.

Application filed March 2, 1899. Serial No. 707,524. (No model.)

1'0 all whom it may concern:

Be it known that I, WILLIAM FRANKLIN FRIBLEY, of Bourbon, in the county of Marshall and State of Indiana, have invented a new and Improved Churn, of which the following is a full, clear, and exact description.

This invention relates to improvements in churns and operating mechanism therefor; and the object is to provide a churn and actuating mechanism that may be operated by comparatively little power or muscular exertion.

I will describe a churn embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a partial section and partial front elevationof a churn and operating mechanism embodying my invention. Fig. 2 is a side elevation with one of the sides of the frame removed, and Fig. 3 is a plan view of a top employed for the churn-cover.

Referring to the drawings, 1 designates a platform from which side pieces 2 2 and a back piece 3 extend upward. The side pieces are connected at the top by a head-piece 4, and a cross-piece 5 is arranged at about their center.

A plunger-bar 6 is movable through openings in the head-piece 4 and the cross-bar 5,

and at its lower end it has a removable connection with the dasher-rod 7 of the churn 8. This removable connection, as here shown, consists of a pin 9, extended through an opening in a stirrup 10 on the lower end of the plunger-bar and having a keeper-pin 11 passed through a transverse opening in the pin 0 at the upper side of the lower head of the stirrup 10.

Having bearings in plates 12 and 13, secured to opposite sides of the back piece 3, is the shaft of a balance crank-wheel lahfrom the wrist-pin 15 of which a pitman 16 extends to a connection with a boss 17, adj ustably connected to the plunger-bar 6. As here shown, the plunger bar 6' is provided with a series of holes, in any one of which the bolt of the boss 17 may be secured in order to regulate or change the throw of the dasher. Upon the outer end of the shaft to which the wheel 14 is attached is a pinion 18, meshing with an interior gear of a drive-wheel 19, having its shaft-bearings in the plates 12 and 13, and on this drive-wheel19 is a crank 20. By this construction a slow motion of the wheel 10 will impart-acomparativel y fast motion to the churn-dasher,and the wheel 14, while not only serving as a crank-wheel, will also serve as a balance-wheel to carry the driving mechanism over dead-centers. v

The cover 21 of the churn has .a funnel shaped portion 22, to the top of which is piv otally connected a strainer-top consisting of two semicircular frames 23 24, pivoted at one side to the funnel portion and having at the opposite sides perforated lugs 25, which are adapted to overlap when the two sections of the top are closed, andthrongh these perforations a fastening-pin may pass.

In each section of the top is a strainer 26, which will permit of entrance of water to the churn,but willprevent splashing out of cream. The cross-bars 27 of the two sections 23 24 are each provided with a semicircular notch, which when the sections are in their closed position form an opening through which the dasher-rod 7 may move. Arranged on the dasher-rod 7 are radial dasher-plates 28, which are here shown asitransversely inclined.

The churn may be held from upward movement relatively to the platform 1 during the operation of churning by means of a bar 29, pivoted at oneend to one of the side pieces 2and adapted to engage upon the cover 21 of the churn and to be secured by a button 30 on the opposite side piece.

By inclining the blades 28, as shown and described, and as the pin 9 turns in the stirrup a rotary motion will be given the dasher during its up-and-down motion, thus thor-v onghly agitating the cream. Cream will be scraped from the dasher-rod by the tubular downward projection on the inside of the churn-cover and through which the rod passes.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a churn and a cover, of a funnel portion on the cover, and a top for the funnel, comprising two segmental frames pivotally connected at one side to swing relatively to each other and having the in each of said sections, substantially as spccithrough openings formed in said sections, and 10 fied. an operating mechanism having connection 2. The combination with a churn and a i with the rod, substantially as specified. cover, of a funnel portion on the cover, a top \VILLIAM FRANKLIN FRIBLEY. for the funnel comprising two segmental \Vitnesses: frames pivotally connected at one side to JOHN D. THOMAS, swing rclatively to each other, a strainer in CHARLES FRIBLEY.
