CREAM AND BUTTER SEPARATOR.-

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed May 16. 1907- Serial No. 374011- To all whom it may concern:

Be it known that I, ALPHEUs FAY, a citizen. of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements, in Cream and Butter Separators, of which the following is a specification.

The object of my invention is to provide improved means for extracting cream or butter from fresh milk and my invention consists in the combination and arrangement of parts hereinafter described and claimed.

The drawing is a sectional elevation of a separator embodying my invention.

On opposite sides of the body A of the separator are secured sockets B adapted to receive stems c on brackets 0. Body A is preferably made of metal enameled on the inside. A shaft D is mounted in suitable bearings c on brackets C and a gear E is pinned or otherwise secured to shaft D. Adjacent to gear E, a shell F is loosely mounted on shaft D and a double pinion G G is rotatably mounted on a stud g carried by shell F. Pinion Gr meshes with gear E and pinion Gr meshes with a gear H which is pinned or otherwise secured to a shell J loosely mounted on shaft D. Shells F and J face each other as shown to inclose gears E and H and pinions G and G. Gear teeth f and j are formed on shells F and J to mesh with gears Z and m on the hollow shafts L and M, which bear at their upper ends in sockets c on brackets C. Openings 0 are provided in sockets c for admitting air to the open ends of shafts L and M. The shafts L and M also have bearings 0 and p in brackets O and P which engage stems c and are secured in position thereon by sets screws 6. Shaft D is provided with one or more crank handles d for operating the separator. Shafts L and M carry combined air pumps and agitators Q and B so constructed that when rotated they draw air through shafts L andM and introduce it into the milk or cream in body A. Simple agitators S and T are also carried by shafts L and M and a draining faucet U is provided for body A.

In operation. upon rotation of shaft D pinions G and G are rotated by gear E, and pinion G meshing with gear H carried by shell J is also rotated. This rotates shell J under the influence of the action from gear E. But shell F is also free to rotate, and being connected with pinions G and G will rotate under the influence of the reaction from gear E. Since the shells F and J are provided with gear teeth meshing with gears Z and m on shafts L and M, it will be seen that shafts L and M will thus be rotated in the directions indicated one under the influence of the action and the other under the influence of the reaction. As the action and reaction are always equal, an equal amount of power will be transmitted to each shaft and an equilibrium established between the two shafts. Thus when the resistance on one shaft becomes greater than that on the other, the corresponding shell will slow down in speed, but take more power, while the other will increase in speed, taking less power. This naturally decreases the re sistance on the slower shell and increases it on the other shell, so that the former is permitted to increase in speed while the latter is forced to decrease in speed. Inasmuch as the agitation in body A necessarily causes different resistances upon the two shafts and shells, their speeds will be constantlyvarying, thus greatly increasing the agitation. In use fresh sweet milk is placed in body A and shaft D rotated to agitate the milk and introduce air therein. .This is continued for from about three to five minutes, when the action is stopped and the milk allowed to come to rest, when the cream will rise to the top of the milk. This will ordinarily take from five to ten minutes after the milk has come to rest. Then by opening faucet U the separated or skimmed milk is .drawn off leaving the cream in body A. By vary ing the volume of skimmed milk drawn ofl the cream may be obtained with any ordinary per cent. of butter fat desired. The faucet is then closed and the operation continued upon the cream in body A. This is continued until the butter is separated from the cream, which will ordinarily take about three to five minutes. The butter may then be removed and worked in the usual manner. The cream residue may then be remixed with the skimmed milk and good and serviceable fresh sweet milk obtained, which contains all the solids originally in the milk except butter fat.

While I have illustrated and described the preferred means for carrying my invention into effect, this is capable of variation without departing from the spirit of the invention. I therefore do not wish to be limited to the exact construction set forth, but

What I claim as new and desire to secure by Letters Patent is:

1. In a cream or butter separator, the combination of a separating chamber; an operative shaft mounted thereon; a shell loosely mounted on the shaft and carrying Within a pair of eccentrically mounted pinions connected together; a driving gear secured to said shaft and meshing with one of the pairs of gears; a second shell loosely mounted on the shaft and carrying Within a concentrically mounted gear meshing With the other pinion, said shells being mounted to inclose and protect the gears and pinions; gear teeth on the exterior of the shells; a pair of agitating shafts in the separating chamber and carrying gears meshing With the gear teeth on the shells, andagitators on the shafts, substantially as specified.

2. In a cream or butter separator, the 20 combination of chamber A; shaft D mounted thereon; shells F and J loosely mounted on shaft D; gear E on shaft D; gear H on shell J; pinions G and G carried by shell F and meshing With gears E and H; gear teeth f 25 and j on shells F and J agitator shafts L and M carrying combined agitators and air pumps Q and R and agitators S and T and gears Z and m meshing With the teeth on shells F and J, substantially as specified. ALPHEUS FAY.
