BARREL-GHURN.

Application filed May 14, 1912.

T 0 all whom it may concern:

Be it known that we, JOHN E. TAYLOR and THOMAS Gr. TAYLOR, citizens of the United States, and residents of St. Louis, Missouri, have invented certain new and useful Improvements in Barrel-churns, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Our invention relates to improvements in barrel churns, and the object of our invention is to construct a churn of the barrel type having trunnions mounted in bearings so that the barrel may be rotated, and to provide for the rotation of the barrel upon its trunnions a pinion connected to rotate with one of the trunnions, a segmental rack in engagement with the pinion and a lever for operating the rack, a crank upon the opposite trunnion and a spring acting on the crank whereby the barrel churn may be 0scillated in order that the contents of the barrel will receive a maximum of agitation in that it is moved from one end of the barrel to the other and, whereby such movement may be accomplished with a minimum of effort.

With the above purposes in view our invention consists in certain novel features of construction and arrangement of parts as will be hereinafter more fully described, pointed out in the claims and illustrated by the accompanying drawings, in which- Figure 1 is an elevation of a barrel churn constructed according to our invention; Fig. 2 is a fragmental elevation of the churn showing the side opposite the one illustrated in Fig. 1; Fig. 3 is a transverse, sectional elevation illustrating the bearing and driving means of the driven trunnion; and Fig. 4 is a transverse, sectional elevation illustrating the trunnion to which the spring balance is secured.

Referring by numerals to the accompanying drawings: 5 designates the barrel, 6 the closure for the barrel and 7 the closure-securing means, all of which parts are or may be of ordinary construction.

8 and 9 designate trunnions provided with integral bases 10 which are secured to the periphery of the barrel at points diametrically opposite each other and at the approximate longitudinal center of the barrel. The trunnions 8 and 9 are supported in bearings 11 which are formed in the castings Specification of Letters Patent.

Serial No. 697,281.

12, and the castings are supported upon a light, metallic frame 13.

14 designates a pinion which is secured to rotate with the trunnion 9.

15 designates a segmental rack arranged to engage the pinion 14 and which is pivotally supported upon the pin 16 mounted in the casting 12 beneath the journal bearing 11 which supports the trunnion 9. Formed integral with the rack 15 is a socket 17 and secured to the socket is an operating lever 18.

The trunnion 8 has secured to rotate therewith a crank 19, the free end of which carries a pin 20 upon which is rotatably mounted a sleeve 21 having an integral ear 22, provided with a number of perforations.

23 designates a cross piece of the frame 13. Secured between the cross piece 23 and the perforated ear 22 is a contractile coil spring 24.

In the practical operation of our improved churn, assuming the barrel filled with cream for churning, the operator oscillates the lever 18 and, through the segmental rack 15 and pinion 14, the barrel is rotated on the trunnions 8 and 9 one fourth of a revolution with each movement of the lever 18. It is to be observed that the arc of the rack is much greater than the arc of the pinion in order that the barrel may be moved a greater distance than the lever 18. It is to be observed that the crank is substantially at right angles to the axis of the barrel so that when the barrel is tilted in one direction, the crank will move in an opposite direction. By this arrangement the spring and crank balance the contents of the churn. When the operating lever 18 is moved in one direction the barrel is tilted in the direction of travel of the lever, and the cream is moved to one end of the barrel so that the weight of the cream will assist the operation of overcoming the tension of the balance spring 24. The spring, being at its greatest tension at this point, will assist the operator in moving the barrel to its other limit'of movement. In moving the barrel the contents is, in each movement, directed to the opposite ends of the churn, hence we obtain a maximum of cream agitation. By reason of the plurality of perforations in the perforated ear of the sleeve which is carried by the free end of the crank, we are enabled to obtain a variable tension of the coil spring in order to provide for difierent quantities of cream to be churned.

We claim:

In a churn, a frame, bearings oppositely carried by the frame, a barrel, opposite trunnions secured to the barrel and arranged to be held by said bearings, a pinion fixed to one of the trunnions and a crank fixed to the other trunnion, an internally eared segmental rack arranged for engagement vvlth said pinion, a lever for the operation of said rack, a sleeve pivotally and detachably secured to the free end of the crank, a contractile coil spring secured at its one end to JOHN E. TAYLOR. THOMAS o. TAYLOR.
