FILTER.
SPECIFICATION forming part of Letters Patent N 0. 450,204, dated April 14, 1891.
Application iiled July l0, 189i). Serial No. 358,316. (No model.)
To all whom it may concern:
Be it known that I, HENRY VVARDEN, of the city and county of Philadelphia, State of Penn-` sylvania,have invented a new and useful Improvement in Filters, of which the following is a true and eXact description, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to the construction of filters, and particularly, though not exclusively, to filters such as are described and shown in the Vpatent to Barton H. Coffey, granted December 17, 1889, No. 417,384.
The object of my present invention is to provide additional and improved means for returning any sand which may escape from the sand or filter chamber into the waterchamber of the filter tothe said sand-chamber.
The nature of my invention will be best understood as described in connection with the drawings, in which it is illustrated, and the novel features which I desire to protect by Letters Patent are herein after pointed out in the claims, reference being now had to the drawings, in which- Figure l is a plan view of the filter; Fig. 2, an elevation taken on a central section; and Fig. 3, a view of the valve, taken on the section-line of Fig. 2.
A is the iilter, which is dividedinto a sandchamber a and a water-chamber a by a partition B, openings b b, &c.,being provided to permit a flow of water from the sand-chamber to the water-chamber.
C is the valve-chamber, D the valve-seat, and E the valve. The water enters the valvechamber C through opening c, and thence its course is regulated by the position of the valve E. lVhen it is desired to filter water, the valve is turned so that the water can pass freely from chamber C through port d to the chamber a. Thence it passes into the chamber a and up through pipe F and port d to the hollow chamber in the valve E, and thence through the port d2 to the pointL of delivery. A change in the position of the valve reverses the current of water for the purpose of Washing the ilter. The water then passes from the chamber C through port c7. and pipe F to chamber al, and thence through the openings b up through the sand in chamber a, escaping through port d into the hollow portion of the valve E, whence it passes to waste through port d3.
The construction of the valve and filter as above described is not new with me, and I have not thought it necessary to particularly show and describe the construction of the valve, because there are many valves by which a similar reversal of the water can be brought about, and any of them, of course, can be used in place of the one indicated in the drawings.
G is a rotating paddle journaled on the pipe F and having a sprocket-wheelg attached to it, which sprocket-wheel engages with another sprocket-wheel g on a shaft g2, which shaft can be rotated by means of a crank-handle g3. This device is not new with me and forms no part of my present invention.
H H H are feet or supports for the filter; I, an opening, of which there may be one or more, formed in the bottom of the Water-chamber of; J, a pipe leading from the said open ing or openings into the chamber a, as shown at j.
K is a valve, by which the opening of pipe J can be regulated or closed.at will.
In filters constructed on the principles des scribed in the Coffey patent, already referred to, and in filters of otherconstruction, sand will from time to time escape from the sandchamber into the chamber through which the filtered water passes, and it is desirable that this sand should be returned to the sandchamber from time to time when the current of water is reversed for the' purpose of washing the sand. In the Coffey patent provision is made for this returning of the sand; but I have found the device consisting of the pipe J, opening into the bottom of the Water-chamber and into the top of the sand-chamber, to be peculiarly efficient and convenient. When the current is directed downward through the pipe F, I open the valve K, and the passage through pipe .I being thus freely opened the water will pass through the opening Iand through the pipe .I into the top of the charnber a, with great velocity, sweeping the sand in the chamber a into the opening I and up through the pipe J into the sand-chamber. When the chamber c. has been cleaned of sand, the valve K is closed, and the water then IOO passes upward through the openings b into the sand-chamber and through the sand to the escape-port.
Vhen iiltering, the Valve K being closed, no unfiltered water can pass through the pipe J into the Water-chamber CL. The area of the pipe J can of course be such as will permit but a portion of the Water to pass upward through it, while the rest passes upward through the sand in chamber a.
I am aware that transfenpipes have heretofore been used leading from the top to the bottom of the sand-chamber of a filter and whereby the sand therein is made to redistribute itselt and pass through alayer of Water in order to clean it, such a device being shown,
. for instance, in Moores patent, No. 395,070,
of December 25, 18,88. In my device, however, the transfer-pipe leads from the water-chamber to the sand-chamber and the return of the sand is effected during the opera-'tion of cleaning the sand in the sand-chamber by passing the Water upward through the mass.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. A lter having in combination a sandchamber a, a waterchamber ct', situated below said sand-chamber and communicating therewith through openings, as b, means for directing water through said chambers in either direction, and a conduit, as J, leading from the bottom of water-chamber co to the upper part ofthe sand-chamber, all substantially as specied, and so that the Water can be at the same time directed from chamber d upward through the sand-chamber and through pipe J to the top of the sand-chamber.
2. Av lter having in combination a sandchamber ce, a water-chamber a', situated below' said sand-chamber and communicating therewith through openings, as b, means for di recting Water through said chambers in either direction, a conduit, as J, leading from the bottom of water-chamber a to the upper part of the sand-chamber, and a valve K in said conduit, all substantially as specied and so that the Water can be at the same time directed from chamber a upward through the sand-chamber and through pipe J to the top of the sand-chamber.
