GENTRIFUGAL FILTER.

A TTORNEYS ROBERT E. LLEE, OF FRANKLIN, LOUISIANA. CENTRIIL'UGAL FILVTER.
Specification of Letters Patent. Application filed June 23,1905. Beria1No.266,555.
Patented July 24, 1906.
To an whom, it may concern.
Be it known that I, ROBERT E. LEE, a citi zen of the United-States, and a resident of Franklin, in the parish of St. Mary and State of Louisiana, have invented a new and Improved Centrifugal Filter, of which the followng is a full, clear, and exact descri tion.
This invention relates centrifu al filters.
The 0 ject of the invention is to provide a cylinder or drum of such construction as will enable the same to be readily adapted to machines of slightly-difl erent sizes.
The invention consists in the construction and combination of parts to be more fully described hereinafter and definitely set forth in the claims.
Reference is to be had to the accompanyto centrifugals or mg drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. igure 1 1s a vertical central section through the casing of a centrifugal to which my invention has been a plied. Fig. 2 is a vertical section through the cylinder or drum of the machine. the drum, and Fig. 4 is a horizontal section through a portion of the drum and taken at a joint formed therein.
Referring more particularl to the parts, 1 represents the casing or body of the filter, w ich is preferably of the usual cylindrical form, having a vertical axis and an annular gutter 2 in the bottom 3. To the up er edge of the body a s lash-ring 4 is attached, which projects inwar l for a well-understood purpose. Within t 's body 1 there is mounted a vertical shaft 5, provided with a pulley 6,
adapting the shaft to be rotated at the usual high speed. The shaft '5 is stepped in a suitable boss 7 u on the bottom 3, and it is provided with a ower head 8 and an u per head 9, said heads being provided on their adjacent faces with flanges 10, which roject toward each ot; er, as indicated. Tliese heads are I connected and may be drawn toward each other by bolts 11, the upper extremities whereof pro ect through the upper head 9, at which point wing-nuts 12 are rovided, as shown. These wing-nuts may e dispensed with, if found desirable, in practice.
In applying my invention I provide a cylinder or formed of two cylindrical sheets or screens 14, of perforated sheet metal or gauze.- As
Fig. 3 is a perspective of rum 13, which has a double wall shown in Fig. 3, these sheets are of approximate cylindrical form, but their edges are not connected to form a perfect cylinder. At their lower edges they are attached to a ring 15, which is of some resilient material, such as steel, rubber," or wood. In this way an annular space 16 is formed between the screens 14, which space is closed below and adapted to receive a filtering substance, such as fine sand, charcoal,or similar material 17. Near the vertical edges of the screenslthe same are connected by vertical bars I8, as indicated most clearly in Fig. 4. These are attached by any suitable means and afford means for retaining the sand, as will be readily understood. In addition to these bars or: strips 18 additional strips 19 are provided around the circumference of the cylinder,
which assist in keeping the cylinder in shape.
The ends of the ring 15 preferably terminate. at the bars or strips 18; but the edges of the.
screens profject therebeyond, as shown. The
edgeg19 slight distance beyond the corresponding strip 18, while the corresponding edge 20 pro j ects a great distance therebeyond, as shown. A similar but reverse arrangement occurs at the inner edges 21.
the outer screen projects only a applied to each otherso as indicated in Fig. 4.
should be understood that the resiliency of In setting the cylinderup in the machine these the ring 15 tends to enlarge'the diameter of the cylinder, and in this way the outersheet thereof forces itself outwardly against the inner faces of the flanges 10. From this arrangement the cylinder will evidently be held in lace by the flanges and will adapt itself to lieads of various diameters, the extent of the lap at the joints varying accordingly. The
width of the space between the screens will be adapted to the particular grade of filtering which is being carried on.
When the drum is placed in the position indicated, the upper head 9 will be tightened into place bymeans of the bolts 11, and the spaces 22 between the stri s 18 and 19 will be filled with sand, as descri ed.
The cylinder is evidently of ve simple construction and may be readily a apted to machines of different dimensions.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A centrifugal machine having a filter-- ing-Wall of resilient material with overlapping unattached edges whereby said Wall adapts itself to various diameters.
2. A filter having a substantially c lindrical filtering-wall having overlapping e ges,
the said Wall having a resilient member embodied therein, whereby it tends to change its normal diameter.
3. A filtering-machine having a cylinder composed of substantially cylindrical sheets of perforated sheet metal, and a ring between said sheets to which the lower ,edges' attach,
said cylinder having vertical strips near the
