COMBINED CHURN AND BUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 550,902, dated December 3, 1895.

Application filed July 13, 1894. Serial No. 517,427. (No model.)

To all whom it may concern:

Be it known that we, CHARLES S. BROWN and FRANK B. FARGO, of Lake Mills, in the county of Jefferson and State of Wisconsin, have invented a new and useful Improvement in a Combined Churn and Butter-l/Vorker, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

Our invention relates to a machine adapted when the parts are in certain relations to each other for use as'a churn and on slight readjustment of some of the parts is adapted for use as a butter-worker.

The invention consists of the machine and its several parts and combinations, as hereinafter described and claimed; but anything herein stated is not to be construed as depriving us of our right to protection hereunder for equivalent devices and of the right to use these devices and their equivalents for every purpose for which they are adapted, notwithstanding no mention of such equivalents is herein otherwise made.

In the drawings, Figure 1 is an end view of our improved machine. Fig. 2 is a top plan view of the same machine. Fig. 3 is a side elevation of the machine. Fig. 4Lis a central longitudinal section of the machine. Fig. 5 is a transverse Vertical section substantially centrally of the case. Fig. 6 is a detail in section of the device for communicating rotary motion to a roller in the case. Fig. 7 is an enlarged view of the end of a bushing fixed in one head of the case and of the sub-head closing the aperture in abushing and a piece of the apparatus for securing the sub-head therein.

A is the frame, of suitable size and form for supporting the operative mechanism thereon. The hollow cylindrical case 10 is provided with heads, one at each end, having annular laterally-projecting rims 11 11 of less diameter than the case fixed severally on the respective heads of the case, concentrically therewith, adapted to serve as gudgeons on which the case is supported and revolved. These gudgeons 11 rest and .travelon flanged wheels 12 12, fixed in pairs on axles 13 13. The two wheels on the axle 13 are located, respectively, atthe two ends of thecase and below and a little at one side of the longitudinal center thereof, and the two wheels on the axle 13 are correspondingly located on the other side of the center of the case. The axle 13 is provided with a cone-pulley 14:, by and through which it is driven by means of a belt running thereon from the power-supply.

The heads of the case are provided centrally with apertures, in and about which are placed bushings 15, secured to the heads of the case. These apertures in the heads of the case are closed by the disk sub-heads 16,which. are fitted in the apertures in the heads and rest against the inner ends of the bushings 15, annular cork-gaskets 17 being fitted in grooves in the inner ends of the bushings and, projecting therefrom, receive the bearings of the sub-heads thereagainst and form tight joints. Rods 18 18, hinged at one extremity to the sub-heads 16, connect the heads to crossheads l9,through which screws 20 turn against bars 21, bearing against the outer edges of bushings 15. These screws 20 are provided with enlarged heads, whereby they are readily rotated. By means of this construction the sub-heads 16 are readily drawn tightly to their seats against the bushings 15 or released there from, as desired. The bars 21 are preferably provided with downwardly projecting legs 21, forming a part thereof, and the bar and its legs are provided with rollers 22 22 on pins fixed in and projecting laterally therefrom, which rollers are so disposed as to bear against the inner surfaces of the bushings 15. This construction permits of the rotation of the case and bushings about the sub-heads and bars 21 when the machine is used as a butterworker.

Two deeply-corrugated rollers 23 23, substantially as long as the interior of the case and disposed parallel with and at opposite sides of the axis of the case, are journaled in boxes therefor in the sub-heads 16. This construction permits the rollers 23 to revolve on their own axes and also to be whirled about each other by the revolution of the case.

Bars 24 2%, located in the case above the sides of the rollers 23 and j ournaled in plates 25, fixed on the sub-heads 1'6, serve, when the machine is used as a butter-worker, being disposed, as shown in Fig. 5, from the sides of a hopper, to carry butterfalling from above onto the rollers 23, by which the butnear their inner edges for the escape of water or milk therefrom, and other apertures in the case closed by the valves 28 are adapted to allow the escape of water or milk there-' through. A door 29 in the side of the case provides access to the chamber of the case.

Means for revolving the case and for rotating the rollers 23 consists of the following mechanism: Sprocket-wheels are provided on the shafts 13 13, and a sprocket-chain 30 runs on these wheels and also on wheels 32 on the hollow spindles 31 31, journaled in the frame. Said sprocket-wheels 32 are splined on thespindles 31, the spindles being movable endwise in their bearings. The spindles are hollow or recessed at their inner ends, so as to receive therein the journals of the rollers 23, and pins 34E, fixed in the journals 33, are adapted, when the spindles 31 are slipped over the journals 33, to enter recesses therefor in the spindles and thereby to lock the spindles to the journals and compel concurrent revolution thereof. The spindles 31 are located in a horizontal plane, and when the rollers are so adjusted as to be in the same plane the spindles are in a right line with the journals 33, so as to be adapted to be coupled thereto and thereby to become practically an extension of the journals. The sprocketchain 30 runs over one of the wheels 32 and under the other one, so as to rotate the rollers 23 inwardly at the top toward each other in opposite directions.

"When the machine is in use as a churn, the sub-heads 16 are drawn tightly to their seats against the bushings 15 and rotate with the case, carrying the rollers 23 and the bars 24 around with the case, the spindles 31 being out of engagement with the journals 33. hen the machine is used as a butter-worker, the rollers 23 are brought into the horizontal plane and the journals are put in engagement with the spindles 31, the sub-heads 16 are loosened somewhat from their seats against the bushings 15, and the case and the rollers 23 are caused to revolve each about its own axis by rotating the driving-shaft, the mechanism being coupled up as shown in Figs. 1, 2, and 3. hen used as a'butterworker, the sub-heads 16 are loosened from their bearings against the bushings 15 and do not revolve with the case 10. For coupling the spindles 31 at both ends of the machine to the journals of the rollers the spindles are provided with heads 35, having annular grooves, and at the front end of the machine a rock-shaft 36 is journaled in the frame, said rock-shaft being provided with upwardlyprojecting fingers 37 having pins that enter and ride in the grooves of the heads 35 at that end of the machine. A radial handle 38, fixed on the rock-shaft, is adapted for oscillating the shaft and thereby throwing the spindles endwise into or out of engagement with the journals 33 at that end of the machine. For accomplishing a similar operation at the rear of the machine the rock-shaft 36 is provided with a downwardly-extending arm 39, connected by a rod 10 to a lever 41, pivoted medially on the frame, which lever ll is at its other extremity connected movably to one arm of alever 42, also pivoted medially on the frame, the furcate extremities of which lever 42 are provided with pins that enter and ride in the grooves in the heads 35 of the spindles 31 at the rear end of the machine. By throwing the handle 38 the spindles 31 at the front and at the rear of the machine are concurrently thrown into or out of engagement with the journals 33 on the rollers 23 at the will of the operator.

Some of the features described and shown in this specification, which we claim to be our invention and for which we are entitled to protection by patent, we have described and claimed in another application for patent, which has been or will be filed about the same date that this specification is filed, and we therefore omit claims thereof herein.

hat we claim as our invention, and desire to secure by Letters Patent, is-
