SPECIFICATIONforming part of Letters Patent No. 749,393, dated January 12, 1904.
Application filed June 28,1901. Serial No. 66,330. (No model.)
To all whom `it may concern.-
Be it known that'I, JOSEPH MEEsMAN, a citizen of the United States, residing at Ottawa, in the county of Putnam and Stateof Ohio, have invented certain new and useful Improvements" in Cream-Separators; and I do declare the following to be afull, 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.`
My invention relates to a machine for the centrifugal separation of cream from milk.
The object of my invention is to secure the separation of cream and milk rapidly, simply,
and cheaply and with less injury to the cream than has been practical in machines heretofore in use and by the application ofless power than has heretofore been required in machines of I attain these obj ects by means of the devices and arrangement oil parts hereinai'ter described, and shown and illustrated in the accompanying drawings, in which- Figure l is a central vertical sectional elevation of the bowl of my machine detached;
and Fig. 2, a side elevation of a portion of two of the hollow truncated cones hereinafter referred to, showing in detail the manner of their connection.
My invention relates to` the interior construction and arrangement or' the bowl of a separating-machine such as is ordinarily operated by hand and is applicable generally to machines of this character as well as powervelocity. Supported within the bowl is a core d, having an axial bore e and of such size as to leave an annular space between the eXte- `rior oi' the core and the interior wall of the bowl a. This core occupies the greater part i oi' the interior of the bowl and may be made be plain, corrugated, or recessed; but I prefer to form it with a smooth outer surface. This core is at bottom supported upon and slightly lifted from the iloor of the bowl by legs or lugs d. e l
f is a tube having a flange f', a head f2 at top, and being threaded at bottom, as at f3.
gis a boss projecting upwardly from the center of the bowl and having a threaded socket to receive the thread f of the tube f. When the tube f is screwed into place, its iiange f is in contact with the top of the conical cap t, which is thus securely held in place. Through the head f2 and through the tube is an axial bore L, which at bottom communicates with horizontal radial openings@l in the boss g close to the iioor of thebowl.
. In the annular space surrounding the core d is a series of sheet-metal rings or sleeves cz, having slightly-inclined walls which slope inwardly toward the top, forming hollow truncated cones. The bottom ring or sleeve ,7c is provided with lugs or scallops l, which lift it above the bottom oi' the bowl a. At top the sleeves /c and le have outwardly-projecting horizontal lugs or hooks m, which engage and support the sleeves la and 7a2. Upon the top of the upper sleeve 7a2 rests a cap o, which is conical and conforms to the interior of the cap or cover b, there being a space between the two. It will be seen that when the sleeves 7c 7c 762 are assembled as here described, with the caps b and o in place, all the parts are detachably connected, so that they will revolve outlet of the pipes p, leading from the interior of the neck of the cap or cover of the bowl, and is designed to permit the escape of cream.
The operation of my device is as follows: Assuming that the parts are assembled as illustrated in the drawings and as above described and that the bowl is mounted in the machine, by which it is caused to revolve at ahigh rate of speed, the milk to be treated is caused to iow into the top of the tube f, from whence it is discharged at bottom through the radial orifices c'. The milk by its superior gravity is carried to the outer part of the chamber of the bowl a, the liquids arranging themselves according to their speciiic gravities. The milk flows upwardly next to the wall of the bowl in the space between the bowl and the rings v f," k2 and out through the pipes p 0, while the cream flows upwardly in the space between the core d and said series of rings, is deiected toward the center of the bowl by the cap 0, and is discharged through the cream-outlet q.
Some of the advantages of the construction here illustrated and described are the following:
First. The core d occupying the greater part of the chamber of the bowl causes the milk under treatment to flow upwardly between the core and the bowl in a thin annular sheet, which permits the whole energy of the machine to be exerted upon a comparatively small. amount of fluid at one time.
' Second. The core being hollow or extremely light takes the place of the same space heretofore occupied by liquid under treatment, which liquid is merely adead weight, requiring unnecessary energy to carry and revolve it at ahigh velocity and interfering with the final separation of the cream and milk, which takes place near the outer circumference of the chamber of the bowl.
Third. In the usual form of separator-bowls the unseparated milk near the axis of the bowl tends to mix with the cream which has been separated, requiring additional time and energy for reseparation. It will be seen that my core d overcomes this objection.
Fourth. The cream which flows upwardly in the space next to the outer wall of the core has in my device an unobstructed passage from bottom to top, and the cream and its fat-globules are not beaten or broken, thus improving thecream and insuring its keeping qualities.
Fifth. If the milk be not separated near the l bottom ofthe bowl or if skim-milk should become entrained with the cream in the cream zone of the space between the core'and the bowl, the milk will find its way against the inner wall of the beveled rings and at the spaces between these rings will escape into the outer or skim-milk Zone of the annular chamber, while the trend of the cream which has escaped into the milk Zone, guided by the outer walls of the rings, will be constantly toward the wall of the core CZ.
For the above reasons it is found in practice that by the arrangement here described the capacity of machines of this class is greatly increased, that the separation is unusually close, that the keeping quality of the cream is enhanced, and that the Inanual or other power required to run the machine is greatly lessened.
Having described my invention, what I claim, and desire to secure by Letters Patent, is-
l. In a cream-separator, a separator-bowl, a core within said bowl having its outer wall adjacent to the inner wall of the bowl, thus forming a thin annular space between said two parts, and a feed-conduit connected with said annular space, whereby milk fed into said annular space assumes the form of a thin cylindrical shell.
