G. NABGELEN & A. G. KLAWITTER.
LARD STRAINER.
APPLIoA'rIoN FILED M1122, 1912.
Patented June 10, 1913.
CHARLES NAEGELEN AND AUGUST Gr. KLAWITTER, OF CINCINNATI, OHIO, ASSIG'NORS TO THE CINCINNATI BUTCHERS SUPPLY CO., OF CINCINNATI, OHIO, A CORPORA- LARD-STRAINER.
To all whom 2f may concern:
Be it known that we, CHARLES NAEGELEN and AUGUST G. KLawrr'rER, both citizens of the United States, and residing in Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Lard-Strainers; and we do declare the following to be a clear, full, and exact description of the invention, attention being called to the drawing which accompanies this application and forms a part thereof.
Lard leaves the kettles and containers in which it has been rendered in consistency of a limpid fluid. l/Vhile still in this condition it is caused to flow through straining devices to free it of matter not reducible to lard like for instance remnants of skin and meat, fibrous matter and cracklings.
Our invention relates to such straining devices and consists of a device constructed with a view to make it adaptable for the particular purpose of rendering lard.
In the following specification and particularly pointed out in the claims at the end thereof, will be found a full description of our invention, together with its operation, parts and construction, which latter is also illustrated in the accompanying drawing, in which Figure 1, is a top-view of our lard straining device. Fig. 2, is a vertical cross-section of the same. Fig. 3, shows in side-elevation, partly in section, one of the separable parts detached.
Our strainer consists of a number of individual strainer-elements, each comprising a multi-perforated diaphragm A, through which the lard is adapted to pass and a frame a whichv supports this diaphragm. These elements are arranged so that a number of them, with perforations of graduated sizes, may be assembled in a manner causing the lard to flow through them successively. The element with the largest perforations is encountered first by the lard which passes successively through the other elements with the smaller perforations, the element through which the lard passes last having the smallest perforations. The frames which support the diaphragms are annular and each consists of two supplementary members 6 and 7, of congruent shape, 1which hold between them the edges of the diaphragms. These frame-members are held to each other by clamping-screws 8.
Specification of Letters Patent.
Application led April 22, 1912.
Patented J une 10, 1913.
serial No. 692,447.
The diaphragms are by preference in form of screens made of wire cloth and to hold their edges securely the opposite surface of the frame-members between which these edges are held are offset as shown at 9, the edge of the cloth being clamped around these o-sets. Three elements are shown in the drawing and they are arranged in form of a stack. They are held alined, one superposed upon the other, by having the opposite surfaces of the frames where they rest upon each other olf-set as shown at 10. The strainer-elements rest in a settling chamber 11, being introduced through the open top thereof. The bottom of this chamber is provided with an annular ridge 12, upon which the frame of the lower-most strainerelement rests, said ridge being spaced from the chamber-wall to which it is concentric and its top being off-set in a manner similar to the opposite surfaces between the frames which are tted to said top. The diameter of this chamber is of a size to permit the lard which discharges from a conduit 13, to flow into the space outside of the strainers, in which space it rises until it overflows therefrom into the upper-most strainer no pressure being applied. The lard passes through all the elements below and discharges through an outlet 14 below the lower-most strainer. Foreign matter which by reason of its size and weight does not flow with the lard is thus held back in the settling chamber, so that the strainers are not encumbered thereby.. This matter may be letout from time to time through a valvecontrolled drain-pipe 15, the inow through conduit 13 being cut o for the time being. The frame of each strainer-element is provided with handles 16, to permit them to be manipulated, lifted out for cleaning and replaced again.
The elements may be readily placed and interchanged by reason of their inter-fitting frames.
Having described our invention, we claim as new:
1. In a lard strainer, the combination of a cylindrical settling chamber, a series of superposed strainer-elements stacked therein and comprising annular frames and diaphragms with openings of graduated sizes,
4the element with the largest openings being uppermost but below the top of the settling chamber, the frames of the elements being smaller in diameter than the inside of the chamber and closely itted to eaeh other to produce an annular space around the elements, but closed against them, a supply conduit to admit lard to this space in which it rises and Hows into the upper -most strainer-element, an outlet Jfor the strained lard below the lower-most element and an independent. outlet from the settling-(maur ber.
2. In a lard strainer, the combination of a cylindrical settling-Chamber having an open top and an annular ridge on its bottom spaced from the side of the Chamber, an outlet in said bottom and within this ridge, a stack of strainer-elements smaller in diam eter than the chamber' and with openings of graduated sizes restino' upon this ridge7 and a supply conduit to admit lard to the space between the outside of the strainer elements and the chamber in which it rises and flows over into the upper-most strainer-element and through all the elements to the outlet below them.
A lard strainer element consisting of two annular, superposed complementary frame-members provided with inter-fitting off-sets between their Contiguous sides, a perforated diaphragm supported transversely between these frame-members and extending with its edge between them and over their inter-fitting oli-sets and screws whereby the two frame-members are permanently secured to eaeh other with the edge of the diaphragm clamped between their olfsets, to form the element complete.
In testimony whereof, we hereunto ailix our signatures in the presence of two witnesses.
