JOHN RAIBLE, MATTHIASY REIS, AND v'JOHANN Iu'rrnn, or cHIcAco,
ILLINOIS Letters Patent No. 99,002, dated January" 18, 1870.
IMPROVEMENT INSELF-CLANING- FILTERS POR HYDRANTS. i'
The Schedule referred to in these Letters Patent and making part of the sama To all whom it may concern:
Be itknown that we,'JoHN RAIBLE, MATTHIAS Rats, and 'JOHANN RITTER, of Chicago, in the county 'of Cook, and State of Illinois,have invented certain new and useful Improvements in Water-Filters; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specitication, and to the letters of. reference marked thereon, like. letters `indicating like parts wherever they occur.
. To enable others skilled in the art to construct anduse our invention, we will proceed to describe it.
Our invention consists in a novel mannerof' constructing a filter,- ,so as to be self-cleaning, the act of shutting of the feed water also opening a valve, through which the accumulated sediment within the filter escapes.
In the drawings- Figure 1 is a vertical section through our iilter, ou
the line :c :c of fig. 2;
Figure 2 is a top plan view of the filter;
Figure 3 is a side elevation oi' the same; and
Figure 4 is a horizontal section, taken on the line y y of fig. 3, looking upward.-
A is the tilter-body, a globular vessel, made in two parts, bolted together, and having stretched'across its interiorthe'filtering-diaphragm a. This diaphragm consists of a'sheet of felt, placed between two sheets of wire gauze, and it is held in place by having its edges lieldbetween the flanges of the two parts of body A, and through which the bolts are passed for holding said parts together. The body.A we mount upon sui-'table legs or frame-work, so as to maintain the 'diaphragm in ahorizontal position.
B isb.` pipe attached to the lower end of the body A, and through which the water is forced, under pressure, into the body and up through the diaphragm.
G is a stand-pipe, attached to the upper end of the body A, and through which the filtered water ascends, and is drawn olf for use through a cock, b, provided for that purpose.
The pipe B we provide with a cock, d, for shutting olf the supply of water, and this cock werprovide with an operating-rod, e, having a handle, f, at its upper end,ra't a convenientl height for grasping with the hand.
The rod ev is vsupported by passing throughv the flanges of'vessel A, and by an arm attached to the y upper end of stand-pipe O, as shown in figs. 1 and 3.
At the lower end of the body A 'we form au opening, k, and over the outside of this opening locate a pivoted valve or gate, j, provided ou its outer`end with a segmental rack, as shown in g. 4.
On the rod e we secure a pinion, t, meshing into the rack on valve j, so that a's the rod e is turned so as to open valve d, and admit water to thebody A, it
valve d is again closed, the opening It will be opened.
To the outside of the body A, we attach a shelf, h, upon which to place vessels while being filled with water from theA filter. p
lVe-also provide .the body A with a cock, g, just above the diaphragm, for the purpose of ldrawing ofi' any standing water above the diaphragm in winter, and thus prevent the apparatus from freezing up and becoming inoperative. The operation of ourdevice is as follows:
The valve d being open, and consequently the valve A j shut, the water flows through pipe4 B into tlie-body pipe C, and is then drawn oli' through cock b.
The water, in its passage. through the felt,'has all the mud, dirt, and impure matters heldin suspension, separated from it, the water passing upward, and the impurities o r sediment falling to the lower end of the chamber.
\Vhen the flow of water is shut oli' by valve d, the hole k is opened, and all the accumulated sediment, 85o., scharged through it.
Any water which does not' pass back through the diaphragm when the hole k is opened, but remains ou top, may be discharged through cock g.
-We areaware that filters have heretofore been made iu which the water could be made to flow throughthe iiltering-medium in either one or the other direction, by setting or altering the mechanism or parts for that purpose and therefore we do not claim such a device; but having thus described our invention,
1. A hydrant containing a filter, so constructed that the water shall flow through the filter when the -h ydrant is opened, and a portion of the water return through the lter and escape at another opening when the hydrant is closed, thereby making the apparatus self-cleaning, substantially as described.
tering-diaphragm A, in combination with the supplypipe B, and the valves or cocks d and j, the latter being arranged to open and close alternately, substantially WM. H. Lo'rz, Qns. H.' ScHENcH.
will operate valve j and close the opening k, and as the A, and passes up through the diaphragm-a and stand 2. The reservoir or vessel A, provided with the fil-`
