FILTER.
Specification of ers Patent. Patented Apr. 25, lltl llttin Application filed November 15, 1915. Serial No 61,625.
To all whom it may concern Be it known that l, MICHAEL PETRrrz, Sr, a citizen of the United States, residing at Bufi'alo, in the county of Erie and State of New York, have invented new and useful Improvements in Filters, of which the following is a specification.
This invention relates to a filter and particularly to that class of filters containing a compressible filtering medium through which water designed for household purposes must pass when the filter is attached to a source of supply.
The primary object of the invention is to provide a filter of the class described with a spring actuated pressure head which contacts with the filtering medium at one end of the filter in such a manner as to prevent the various distendible layers of filtering material contained therein from becoming distended under the pressure of the water passing through the filter.
Another object of the invention is to provide a filter with a supply pipe which extends a considerable distance within one end thereof, in order to insure water entering the filter through said pipe, contacting with a compressible filtering medium.
A further object of the invention is toprovide a covering for the perforated end of the Watersupply pipe which is disposed within the filter and secured thereto in such a manner as to prevent a compressible-stratiform filtering medium surrounding the perforated end of the supply pipe, from becoming distended through the pressure of the water in the supply'pipe.
it still further object of the invention is to provide a filter with removable closures which normally serve to permit of the ready removal or insertion of the stratiform filtering medium at the bottom of the filter, but also support the supply pipe and pressure head respectively.
With the above and other objects in 719W? the improvement'resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.
in the drawing: Figure 1 is a vertical longitudinal sectional view through a filter constructed in accordance with the invention Fig. 2 is a transverse sectional View on the line 22 of Fig. 1, and Fig, 3 is a transverse sectional View on the line 33 of Fig. 1.
Like characters of reference designate corresponding parts throughout the several views of the drawing.
The numeral 1 designates the improved filter, which comprises a tubular body 2 in which is disposed a distributing pipe 3,
a pressure head 4, and a filtering medium 5.
The body 2 is flanged at the opposite ends thereof as indicated at 6, said flanges forming shoulders 8 for the reception of a gasket or packing 9. The opposite ends of the body 2 are closed by caps 10 and 11, the cap 10 having an axially extending and threaded aperture 12in the portion thereof which is reduced to provide a hexagonalshaped extension 18. The bottom portion of the cap 10 is reduced to provide an annular shoulder 14 adapted to be received within the flanged end of the body 2 and to rest upon the gasket or packing 9. The body portions of said caps are recessed to..provide chambers 15 which when the caps are connected with the body aline with the chamber therein and form a continuation of the same. Spaced circumferentially about the flanged ends of the body 2 and the caps 10 and 11 are lugs 16, apertured to receive fastening elements 17, by means of which the caps are secured to the body The cap 11 is provided with an outlet port 18 which communicates with the chamber 15in the cap and has its opposite end enlarged and threaded for the reception of a spigot, by means of which the filtered water may be withdrawn from the filter.
'lhreadedly mounted in the aperture 12 in the extension 13 of the cap 10 is one end of the fluid distributing pipe 3 perforated for a portion of its length, as at 20, the other end of the distributing pipe being closed by a plug of some suitable porous material, as indicated at 21. Surrounding the pipe 3 throughout its entire length and covering one end of the plug of porous material contained in the end of said pipe is a tubular casing 22, formed from some suitable material such as cheese cloth. she pipe 31 is provided adjacent the end thereof which is threadedly engaged in the aperture 12 with an annular groove adapted to receive a split ring 23 which is slipped over the covering 22 and forces a portion thereof within the annular groove 23 whereby the covering 22 is prevented from disengagement with the pipe 3.
Mounted for longitudinal movement in i is connected.
the body 2 is the pressure head 4 perforated, as at 25, and provided with a depending stud 26. The openings 25 in the pressure head are adapted to permit the water which passes through the filtering medium to enter the chamber at one end of the body 2, the length of the said chamber being regulated by the depth of the recess 15 in the cap 11 and by the distance of the pressure head from the end of the body to which said cap Interposed between the bottom of the recess 15 in the cap 11 and wound about the stud 26 is a coiled expansion spring 28, the purpose of which is to maintain the filtering medium under compression.
The filtering medium 5 comprises alternate layers of compressible material such as cotton, charcoal or the like, which are positioned in the filter body in such a manner that the uppermost layer of cotton surrounds the end of the supply pipe 3 and prevent the diffusion of the adjacent layer of charcoal. To prevent the lowermost layerof cotton from closing the openings 25 the pressure head 4 under the pressure of water a pad of cheese cloth is interposed between the pressure head and bottom layer of cotton.
When it is desired to use the filter the extension 13 is secured to a pipe connected with a water main or other source of supply and the faucet which is designated at 30 closed. It will now be seen that the water which passes through the perforations 20 and the plug 21 in the end of the pipe 3 will be retarded by the cheese cloth sack 22 so that the water will flow between the sack and the pipe for the greater portion, of its length and be equally distributed throughout the length of the top layer of cotton 26 to thoroughly saturate the same before coming in contact with the layer of charcoal 26. Any odor in the water will be absorbed and the water allowed to continue through the layer of cotton 27 below the layer of charcoal 26 where any impurities which have not been absorbed by the charcoal or layer of cotton surrounding the pipe 3 will be retarded, while the water passes through the cheese cloth pad 29 over the openings 25 in the pressure head at. The pressure head 4 exerts sufficient pressure upon the filtering medium to cause the same to firmly contact with the inner peripheral wall of the body 2, so that the water escaping from the supply pipe 3 through the perforations 20 therein is prevented from gaining access to the chamber 15 along the inner peripheral wall of the body 2.
Having thus described the invention, what I claim is:
1. In a filter, a hollow body, filtering material disposed within said body, a cap for attachment to a supply pipe closing one end of the body and recessed to receive a portion of the filtering material, and a distributing pipe carried by said cap and perforated between its ends and extending within the body within the filtering material for the greater portion of the length of the pipe.
2. In a filter, a hollow body, filtering material disposed within said body, a cap at one end of the body for connection with a supply pipe and recessed to receive a portion of the filtering material, -a perforated distributing pipe having one end connected .-with the cap and extending within the filtering material within the body below said cap and a porous plug closing the lower end of the distributing pipe.
3. In a filter, a hollow body, filtering material disposed within said body, a cap at one end of the body for connection with a supply pipe and recessed to receive a portion of the filtering material, a perforated distributing pipe having one end connected with the cap and extending within the body of the filtering material for the greater portion of the length of said pipe, a porous plug closing the lower end of the distributing pipe, and a fabric covering interposed between the filtering material and the pipe and covering one end of the porous plug.
-l. In a filter, a hollow body, filtering material disposed within the body, means for compressing said material arranged within the body at one end thereof, a cap at one end of the body for connection with a supply pipe, a perforated distributing pipe carried by said cap and extending within the body and within the filtering material, a fabric covering for said pipe removably connected therewith, and a fabric pad interposed between the filtering material and the means for compressing the same.
In testimony whereof I afiix my signature in presence of two witnesses.
MICHAEL PETRITZ, SR.
