SPECIFICATION forming part of Letters Patent No. 564,657, dated July 28, 1896.
Application filed July 18,1395. Serial No. 556,385. (No model.)
To LZZ whom, it may concern.-
Be it known that I, HENRY G. STIEBEL, Jr; a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Electric Water-Sterilizing Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.
My invention has relation to improvements in electric water-sterilizing apparatus; and it consists in the novel arrangement and com bination of parts, more fully set forth in the specification and pointed out in the claims.
In the drawings, Figure l is a middle vertical longitudinal section of the apparatus. Fig. 2 is a transverse section on the line a: .fr of Fig. 1. Fig. 3 is a detail elevation of a modified form of the tube conveying the water or other iuid to the lter-chamber; and Fig. 4 is a section on y 'y of Fig. 3, with resistance-coil attached.
The object of my invention is to construct an electric water-sterilizing apparatus which will simultaneously heat and .filter the water passing through the same, thereby sterilizing the water with respect to any injurious animalculae or bacteria, destroying the lattercompletely and rendering the water wholesome and fit for drinking and cooking purposes. i
In detail the invention may be described as follows:
Referring to the drawings, 1 represents a preferably annular casing having an outlet or delivery pipe 2 for the filtered water. The upper end of the casing is closed by a plate 3, provided with an exterior iiange a adapted to come in contact with the inner surface of the upper end of the casing, said plate being temporarily secured by the binding-posts 5, carried by the arms 6, pivoted between suitable lugs 7 carried by the outer wall of the casing. Confined between an inner flange 3 formed with the plate 3 and a corresponding flange 9 carried by the bottom of the casing is a porous cylindrical diaphragm IO, having a series of iilter-sheets 1l, of paper or other suitable material, placed adj acent there to, said sheets being confined and held in place between said outer porous diaphragm ducted to a suitable lter-chamber.
10 and a similar inner diaphragm 12. The clear-water chamber 13 is formed, of course, around the outer diaphragm. `The filterchamber 14. is provided with a cylindrical deiiecting-cup 15 open only at the top, the bottom resting and being confined within the walls of aninner flange 16 carried b /the/ bottom of the casing. Adjacent to the ange 16 is an outlet-pipe 17 for flushing the filterchamber when necessary. Carried by the plate 3 and secured thereto by means of a cap-screw 18, which latter is adapted to be secured to any suitable supply-pipe, is an open tube 19, of suitable non-conducting or insulated material, through the interior of which passes one loop of a conducting-wire 20, secured by a binding-post 21 at the top of the plate 3, the return loop of the wire being coiled about the outer periphery of the tube 19, the whole forming a resistance-coil for the electric current passing through the wire.
A modification of the tube 19 is shown in Fig. 3, wherein I have formed a spiral groove 2-5 along the exterior of the tube, and where, as seen in Fig. 4, each loop of the conductingwire is made in the form of a coil 26, the outer coil being wrapped around and following the outline of the outer groove, this arrangement resulting in a greater quantity of wire' and a corresponding increase in resistance material.
The deflecting-cup serves to bring the iniiowing water in contact with the resistance coil, the flow of the water being indicated by the arrows. The resistance-coil upon a current passed therethrough heats the water to a point where all injurious organisms are destroyed. The water thus purified passes through the filter diaphragm into the clearwater chamber, whence it is drawn for use.
I do not limit myself to the precise form or arrangement of the parts here shown. It is obvious that instead of the cylindrical form a rectangular form may be given to the casing and the other parts accordingly. It might also be possible to remove the resistance-coil from the relation it occupies in the drawings, so long as the water heated thereby were con- It is also obvious that otherliquids besides water could be passed through the present apparatus.
Having described my invention, what I claim is 1. In a Water-sterilizing apparatus, a suitable casing, a iilter-cha1nber and a clear-Wa ter chamber in the saine, a diaphragm between said chambers, suitable inlet and outlet openings for the filter and an electric resistance-coil conined Within the filter-cham ber, substantially as set forth.
2. In a Water-sterilizing,` apparatus, a suitable casing, a cap-plate for the sanie, suitable porous diaphragms held between the capplate and the bottom of the easing, filteringsheets located between the diaphragins, a lter-chamber formed Within the diaphragms, a dei'lecting-eup secured to the bottom of the casing Within the filter-chamber, a feed-tube leading into the deilectingj-cup, a suitable resistance-Coil carried by the tube and having;` the wires thereof passed `through the capplate, means for securing the cap-plate to the casing, and suitable pipes leading respectively from the iilter-chanlber and the clear-water chamber, substantially as set forth.
3. In a Water-sterilizing,` apparatus, a easing, a feed-tube projectingthereinto, an exterior spiral groove formed on such tube, a resistance coil supported by sueh groove, and means Within the easing; for filtering' the Water after being,` heated by the coil, substantially as set forth.
4. In a Water-sterilizing apparatus, a easing, a non-conducting or insulated feed-tube projecting thereinto, an exterior spiral groove formed on such tube, a suitable coiled loop supported by said groove, and means Within the casing for filtering the water after being heated by the loop, substantially as set forth.
In testimony whereof I' ailix my signature in presence ol two Witnesses.
