CHARLES IV. SLAGEL, OF DAVENPORT, NEBRASKA.

Morn/E POWER FOR CHURNS.

SPECIFICATION forming part of Letters Patent N 0. 417,104, dated December 10, 1889.

Application filed April 27, 1889. Serial No. 308,793. (No model.)

T0 to whom it may concern Be itknown that 1, CHARLES W. SLAGEL, a citizen of the United States, residing at Davenport, in the county of Thayer and State of Nebraska, have invented certain new and useful Improvements in Motive Power for Churns; and I do hereby declare the followingto beafull, 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 has relation to churns, and has for its object to produce a churn which is very simple in construction, which can be operated by either hand or motive power, in which the throw of the dashers employed can be readily varied, if desired, and in which the frame supporting said dashers, as well as the means for operating the same, maybe readily placed in position upon the vessel or removed therefrom when the process of churning is completed.

My invention consists in the combinations of parts, as hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of my improved churn, the vessel being partly broken away to show the arrangement of the dashers; and Fig. 2 is a top plan View.

A indicates the vessel, which may be of any desired shape, though I pref er to make it cylindrical, as shown. Near the upper edge of said vessel, upon either side, is secured in any suitable manner a plate a, each of which is provided with two rectangular openings (0', for a purpose presently described. For supporting the dashers, as well as the means for operating the same, I employ a frame B, which is preferably constructed of iron, in order that the same may be durable and not liable to warp from moisture, the. It consists of the four uprights Z), connected at top and bottom by the longitudinal girts Z) Z2 respectively, and the transverse pieces D The lower ends of the uprights form feet which, when said frame is supported in position upon the upper edge of the vessel A, fit within the rectangular openings to in the plates or, and are thereby held firmly in place.

C 0 indicate the dashers that I employ,

which are, as ordinarily made, flat, and are provided at. their upper edges with pins 0, which pass through guide openings or slots 0" in the longitudinal girts b of the frame.

In the operation of the churn it is my intention to impart a simultaneous oscillatory movement to the dashers in opposite'directions. The range of movement that I prefer to impart to each of said dashers is such that the are that they describe will be equal to about one-fourth of the circle. I have, however, provided means whereby the range of movement of either or both ofsaid dashers may be readily varied, if desired, and will hereinafter appear.

For operating the dashers in the above-described manner, I employ the following means: Rigidly mounted upon a transverse shaft (1, having its bearings in the upper piece I) of the frame, is a gear-wheel D, which meshes with a pinion E on a transverse shaft 6, also having its bearings in said pieces I), said shaft also carrying a fiy-wheel F.

The means for operating the dashers C and C from the shaft 6 are located upon opposite sides of the frame B and are identical in arrangement and operation. Upon each end of the shaft 6 a crankf is mounted, upon apin f of which is pivoted one end of a rod f, the other end being pivoted upon a pinf projecting from the upper end of a rock-lever G, pivoted upon a pivot g.

H II are levers, one end of each of which is forked at II to embrace the lower ends of the levers G G, and are pivoted upon pins g, while their opposite ends are pivoted upon pins g of the crank-arms I I, which are rigidly secured to the pins 0 on the dashers .0 and O.

In order that the dashers may be oscillated in reverse directions with respect to each other, the cranks f f upon the ends of the shaft e will. be oppositely located thereon with respect to each other, as will be understood, as is plainly shown in Fig. 2.

The shaft (1 may be operated by hand, for which purpose I provide the handle J, or by power, in which case I mount a belt-pulley upon said'shaft, as will be understood.

For varying the throw of the lower end of either or both of the rock-levers G, and consequently the throw of the dashers, I provide said lever with a series of openings 71, and make the pivot g removable, so that by passing the pivot 9 through the different openings the above object is accomplished.

It Will be seen that in the operation of the machine the revolution of the shaft 6 will, through the media of the cranks f and rods f rock the levers G, and the latter will, through the media of the levers II and crank I, cause the dashers to be oscillated simultaneously in opposite directions with relation to each other.

I clain1 1. In a churn, the combination, with the cylindrical vessel A, having secured upon its upper edge the plates (0 a, provided with rectangular openings a, designed to receive and support the frame 13, of the transverse shaft 6, journaled in hearings in said frame and carrying a fly-Wheel F, and a gear-Wheel l1, meshing with a like wheel D on the transverse shaft d, the cranks ff on each end of the shaft 6, the rods f leversGl'I, and cranks I I, arranged on opposite sides of the frame for imparting motion to the dashers C and C, substantially as described.

2. In a churn, the combination, with the cylindrical vessel A, having secured upon its upper edge the plates to a, provided with rectangular openings a, designed to receive and support the frame B, of the transverse shaft 6, journaled in bearings in said frame and carrying a fly-wheel F, said shaft having upon its ends cranks ff, the pivoted levers G G rovided with a series of o enin 's h for regulating the throw of the dashers, the pins 9, the rods f connecting the upper ends of the levers G G with the cranks ff, and the adjustable levers H II, pivoted to the lower ends of the levers G G, and connected at their opposite ends to the cranks I I on the dashershafts, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
