'ALBERT GUDEMAN, EUREKA, ILLINOIS.
SPECIFICATION forming part of Letters Patent No. 546,527, dated September 17, 1 895.
Appncain nea April 1s, 1895.
To @ZZ whom it may concern.:
Be it known that L'ALBEET GUDEMAN, a citizen of the United States, residing at Eureka, in the county of Woodford and State of Illinois, have invented certain new and useful Improvements in Filters; and I do hereby declare that the following is a full, clear, and eX- act description of the inventio'n, which will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to filters, and more particularly to that class of filters which are used for cisterns and other outdoor work.
The object of the herein-described device is to catch and filter perfectly the rain-water as it comes from the roofs of buildings, &c.
In the drawings herewith, Figure l represents a side elevation of the tilter, showing the interior, one side being removed. Fig. 2 is an edgeview of the iilter, showing the interior through an open door. Fig. 3 is a perspective view of a tray used in the ilter. Fig. 4 is a detail in section of a portion of said tray. l
The lter-casing isv shown at A and is made in rectangular form, butfmay be made in any form desired. The interior of the filter is reached by opening the door B on one end of the casing. The top of the casing is provided with a lifting door or lid C. This door forms a part only of the top of the ilter-casing. The fixed portion of the top carries or has opening into it a pipe D, which delivers the Water to be filtered.
A strainer E is placed under the top ofthe filter and under the pipe D. Under the said strainer is tixeda board F, which may or may not be parallel with the said strainer E.
A drain-spout G is secured to and opens .through the door B and is placed to receive any foreign matter and deliver it outside the filter.
Beneath the board F, which slants substantially as shown, is placed a tray H, which slants in the opposite direction to the board F. The lower end of the tray H is provided at the bottom with an opening and a short spout H to allow water to pass through. A strainer or sieve H2 is secured in the end of the tray above the said opening and spout H in any suitable manner and position. The
tray is illed with charcoal of medium -sze or Serial No. 546,289. (No model.)
with any other suitable filtering material. Below this trayv H is located a second tray I, which slants iu the reverse direction to that of the tray H and carries its spout H at the opposite end-z'. e., the end having the lowest level. This tray is filled with a slightlyliner grade of charcoal or other material having filtering capacity. The remaining space below the trays is filled with a series of trays similar to those described, and all slant in alternate opposite directions, and are each provided with finer filtering material as the bottom is reached.
The lower tray opens into and deposits the filtrate upon the bottom J of the filter, and from thence the said filtrate escapes through the pipe K to the cistern or other receiver.
The trays may be made of wood or metal,
galvanized iron being preferable, and may be mounted on slides similar to drawers, if desired, and so arranged as to be easily drawn out separately or as a whole from the casing.
The filtering material may be placed in a spirally-winding tray running from the top to the bottom of the casing,'or the tray may be made in any shape desired which will properly convey and iilter the Water. This is excellent for filtering all other fluids.
The operation of the device is as follows: The Water entering the filter from the spout or pipe D at the top drops upon the strainer E first, and on passing through this all rubbish and insects are kept from passing farther, andthe spout G serves as an exit for the same. Water on passing through this strainer falls upon theinclined board F. Passing down this, it runs into the tray H and down through the charcoal to the next tray below, &c., until at the bottom the water is perfectly clear and free from all foreign matter. y
What I claim as new, anddesire to secure by Letters Patent,risv In a filter, the combination of the casing A substantiallyof the form shown, a lid C, a conduit passing through the top ofy said casing, an outlet pipe in the bottom of casing, an inclined strainer placed beneath said conduit, a spout at the lowerend of said strainer, a drain board F placed beneath and parallel with said strainer substantially as shown, a series of iltering trays below said drain or running board substantially in the manner shown and described, said trays being slanted in alternate directions and having an opening in the lower extremities thereof, a strainer covering said openings, a filtering material placed in said trays and all arranged substantially in the manner and for the purposes set forth and described.
In testimony whereof I aix my signature in presence of two witnesses.
