CHURN.

Specification of Letters Patent.

Application filed April 19, 1911.

Patented July 18, 1911. Serial No. 622,102.

To all whom it may concern:

Be it known that I, CHARLES A. MGOANN, a citizen of the United States of America, residing in Blair township, in the county of lVashington and State of Nebraska, have invented certain new and useful Improvements in Churns, of which the following is a specification.

My invention relates to improvements in churns in which an upright cylindrical receptacle or can is mounted on springs and vertically reciprocated to agitate, beat and intermix the contents thereof; and the objects of my improvement are, first, to provide an elastic vertically-vibratory support to carry a churn body or cream can whereby the contained cream may be agitated and beaten to break the milkfat globules and separate the butter-fat from the serous parts; second, to provide a base-seat for the body or can in rigid connection with a coverclamp to also fasten the can in the vibrative end of the support; third, to provide means to alternately draw the top and bottom of the vertically reciprocating can toward the fixed anchorage of its vibratory support, whereby the forward end of the contents of the can, in both directions of its movement, are thrown inwardly, against its centrifugal tendency, to agitate and completely and continuously intermix said contents; fourth, to aiford facilities for varying and adjusting the flexibility of the elastic support according to the quantity or weight of the content of the can; and, fifth, to facilitate the easy connection of the ends of the horizontally disposed bar-springs with the can-carriage or clamp and with the fixed support and conserve them against breakage or set at these points] These and other minor objects more particularly hereinafter set forth, I attain by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a side elevation of the churn, the can-seat, can and cover shown in vertical section; Fig. 2, a top view, parts of the cover and top of the can cut away; Fig. 3, an underside view; Fig. 1, a vertical section on the broken line 2 of Fig. 1, giving a front elevation of the stationary attaching support and spring adjusting contrivance; Fig. 5, a rear elevation of the U-shaped body of the can-clamp or carriage disconnected from the other parts; and Fig. 6, a top view of the cover alone. In all of which views similar reference numerals refer to like parts.

The vertically-vibratory support by means of which the cylindrical receptacle or can 3 1s longitudinally and vertically reciprocated, comprises the horizontally disposed elastic bars or springs 4 and 5, having the intermediate

spiral coils

6 and 7. These springs are fastened at their rear ends to the stationary attaching support 8 and their front or vibrative ends rigidly fastened to the can-carriage and clamp. The stationary support consists of the worked and finished plank having beside its other connections the perforations 1, l and 1 by which it is lagscrewed or bolted to any vertical wall or post. The clamping can-carriage consists of a U-shaped body having a long base 9 disposed vertically, a lower horizontallydisposed leg 10 of length to underlie and support the disk 11 attached thereon to form a seat for the can; and a shorter top leg 12 terminated in the knob 13 having a vertical threaded perforation to take the wheel-screw 14: disposed centrally above the seated can. And a curved guide and stop 15 is fastened to the back edge of the diskshaped can-seat to stop the inserted can centrally on the seat beneath the screw-wheel.

The cover 16 has the annular groove 17 to receive the beaded rim 18 of the can 3 into which it closely fits. The cleat 19 on the top of the cover has the central socket 20 to receive the point of the wheel-screw when it is turned down to press the cover tightly on the can and fasten the can seated in the carriage. The cover also has the vertical perforation 21 through which the contents of the can are aerated, examined or tested and is provided with the stopple 22 as shown in Fig. 2.

The lateral flange 23 of the U-shaped clamping body is of width equal to the width of the spring-bars and has curved

bends

24 and 24 at the junctions of the horizontal leg portions with the vertical base of the U. The oppositely

curved lugs

25 and 25 are spaced away from the legs of the flange to closely receive the spring-bars therebetween and the interposed forward ends of the springs are fastened to the flange by the

bolts

26 and 26 disposed vertically through both. By this means the front ends of the springs are rigidly fastened to the can carriage and must fleX at this connection when the carriage is vertically reciprocated; but the flexure being around the curved lips at the mouths of the recesses in which the springs are seated said springs are preserved against set or breakage at these points. The rear end of the lower spring at is similarly fastened to the stationary supporting plank; the upturned vertical end portion 27 is connected with the horizontal part by a long curve 28 and interposed between the thin straight chafe-plate 29 and the cap-plate 230 with through

bolts

31 and 31 to fasten them to the support; and the capplate has the more shortly curved end 82 overlapping the angle bend in the spring as shown.

To attach the top spring to the stationary support a horizontal cleat 33 is bolted across the front of the support; this cleat has the spaced ears 3 1 and 3a and the pin disposed horizontally through the ears and across the space between. The rear end of the spring has a U-shaped bend 36 to engage the pin between the ears and form a hinged connection therearound, as shown by dotted lines in Fig. 1. An integral end portion of the spring is bent downwardly to form a vertical arm 37 having the forked terminal 38. The threaded rod 39 is attached to the face of the stationary support by the base-plate stO and is disposed horizontally through the forked terminal of the arm. A wheel-nut il is mounted on the threaded rod back of the fork and the tail-nut 12 is mounted on the rod forward of the interposed forked end. By turning these nuts to Hex the forked end of the arm forward the elastic force of the spring is increased to level up the springs and balance their flexibility against a heavier content 43 in the can, or to increase the working elastic force of the springs in any case as may be desired. By attaching these springs rigidly at both ends, whereby each must simultaneously flex oppositely at opposite ends, much lighter springs serve to supply the required elastic force than would be required if the vibrative ends were hinge jointed to the carriage; further they act more positively, more smoothly and with less noise.

lVhen the can is charged and fastened in the carriage, and if necessary the springs properly adjusted, the elastic support is highly sensitive to vertical vibration. By a touch of the hand in alternate pressure and release on top of the can cover or carriage they are excited into rapid strong vertical reciprocation. By this movement the content, which as shown should never on tirely fill the can, is thrown up and down with great force alternately against the rel.- atively unyielding cover and bottom. There is a further movement of the carriage and contained can, which renders my contrivance most useful in mixing compounded solutions, such as spraying mixtures for vegetation and the preparation of beverages; it being obvious that the size of the contrivance may be varied as required and different cans for different purposes readily seated in and removed from the carriage :The intermediate spirally coiled portions of the springs are disposed as nearly as possible in the plane of vibration and are coiled oppositely in opposite springs.

then in operation the can moves upward the coil of the top spring partially unwinds and expands in size to in effect shorten the distance between the opposite ends of the spring; simultaneously the coil of the lower spring is wound closer decreasing its diameter and lengthening the distance between the connected ends of this spring. By this means the top of the can is drawn back wardly as it arises, while its bottom is held outwardly until at the end of the upward movement the can is in the position indicated by the broken line of Fig. 1. By the reverse or downward movement the lower end of the can is drawn backwardly and a reverse position attained as indicated by the broken line 4:5. This sudden tilting of the can in opposite directions in connection with the simultaneous forceful. vertical reciprocation thereof continually and rapidly intermixes and beats together the contents. This action being so thorough and efficient that in churning butter from cream the most rapid service is performed requiring no other dasher or agitator than the plain containing receptacle or can which is easily filled emptied and cleaned.

I claim:
