SPECIFICATION forming part of Letters Patent No. 620,621, dated March '7, 1899.
Application filed November 29, 1898. Serial No. 697,781. (No model.)
To all whom, it' may concern:
Be it known that I, HENRY AUGUSTUS VEA- ZIE, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in Filters, of which the following is a specification.V
My invention relates to iilters; and it consists in the peculiar and advantageous construction hereinafter described, and particularly pointed out in the claims appended.
In the accompanying drawings, Figure lis a vertical section of myimproved filter. Figs. 2 and 3 are transverse sections taken in the planes indicated by the broken lines 2 2 and 3 3, respectively, of Fig. l.
Referring by' letter to the said drawings, A is the upright cylindrical casing of my improved lter, and B are su pporting-legs,which are connected to the side of the casing and extend outwardly and thence downwardly from the same for a purpose presently described. The casing A is preferably cast in one piece and provided at its lower and upper ends with outwardly-directed flanges a. It is valso provided at its lower and upper ends with heads C D, the said heads being detachably connected to the flanges a by bolts and nuts or other suitable means and the connections being rendered water-tight by gaskets b, interposed between the heads and lianges after the manner shown.
E is a water-supply pipe which leads from a pump or other source of supply and is let into the casing A adjacent to the lower end thereof.
F is an eduction-pipe which communicates with the interior of the casing adjacent to the upper end thereof and is designed to conduct clarified water from the filter to a stand-pipe, tank, or other receptacle, and G is a pipe which is designed for the withdrawal of mud or other sediment from the cylinder. The pipe G is of necessity provided with a suitable valve c, and the pipes E F are by preference provided with similar valves, so as to permit of the iniiow and outflow of water being stopped when desired. 'The pipe G is preferably arranged in the same or approximately the same horizontal plane as the pipe E and at an opposite point to said pipe E, and consequently when the valve of pipe F is closed and those of the pipes E G opened the head of water from the pump or other source of supply will quickly wash all of the mud and other sediment that is collected in the lower portion of the casing and through the pipe G.
The filtering material may be of any suitable kind, although I prefer to employ a layer of charcoal ofinterposed between two layers of sand d and separated from the same by pieces e of felt', canvas, or other suitable material. This iltering material is placed and held between two foraminated diaphragms II I and is preferably separated from the diaphragms by pieces f of felt, canvas, or other suitable material. It is designed to be introduced into the casing through an upper manhole g and removed when necessary through a lower manhole 72,. When desirable, however, it may be removed from the lower end of the casing, as will be presently described.
The lower diaphragm I-I is connected to and supported by legs i', which rest on the lower head C of the casing, and hence it will be seen that when the head C is disconnected from the casing the diaphragm, as well as all the superposed layers of filtering material, will drop out of the lower end of the casing. In this way the lower diaphragm may be readily removed to be cleared of collected sediment, and the old filtering material may be discharged from the casing into a receptacle placed between the legs B to receive it.' It Y follows from this that the lower manhole h is not essential, and as the upper head D is removable the upper manhole g is also not essential. I prefer, however, to provide the said manholes for the convenient introduction and removal of filtering material when it is not expedient to remove the heads C D.
It is desirable to hold the filtering material under pressure, and I have provided an improved construction for this purpose which is advantageous because it precludes leakage at the upper end of the casing. This construction comprises the diaphragm I, having a threaded aperture t' and a peripheral notch j, a vertically-disposed spline k, which may be and preferably is formed integral with the casingA and is designed in conjunction with the notch j of the diaphragm to hold said diaphragm against rotation and yet permit it to freely move up and down, and va hand-screw IOO J, which engages the aperture z' of the daphragm and takes through a suitable stuffingbox Z on the head D. This hand-screw J has a suitable handle m at its upper end and is provided below the head D with a stop n, which, bearing against the under side of the head, is adapted to hold the screw against endwise movement and yet not interfere with its turning.
By turning the hand-screw in one direction the diaphragm I is moved downwardly to compress the ltering material, and by turning the screw in the opposite direction the diaphragm is raised to loosen the material. By reason of the construction described the diaphragm may be very easily depressed and raised through the medium of the screw J without disconnecting any part of the lter and leakage at the point where the screw takes through the head D is absolutely prevented. This renders my improved construction superior to those constructions in which the adjusting-screws of the diaphragms take through threaded apertures in the heads and in which there is always more or less leakage at such points, especially in those casesl in which the water enters the filter under a strong head.
K is a cock through the medium of which water may be drawn from the lter whenever it is desired to ascertain the condition of the water.
It will be appreciated from the foregoing that my improved filter while very simple and cheap is highly efficient in operation and is calculated to quickly and thoroughly filter and clarify the water which passes through it. It will also be appreciated that the sediment collected at the lower end of the casing may be readily removed by simply closing the valve of pipe F and opening the valve of pipe G, that the lower diaphragm and all of the filtering materials may be readily discharged from the casing into a receptacle placed to receive them, and that the upper diaphragm may be adjusted without liability of leakage at the upper end of the casing, all of which are material advantages.
Having thus described my invention, what I claim isl. In a filter, the combination of a casing having an interior spline disposed in the direction of its length and also having a head provided with a stuiiing-box, a diaphragm arranged in the casing, a second diaphragm movable toward and from the rst-named diaphragm and having a screw-threaded aperture and also having a peripheral notch receiving the spline of the casing, and ahandscrew arranged in the stuffing-box of the casing and having the lower threaded portion taking through the threaded aperture of the movable diaphragm and also having the stop arranged to bear against the inner side of the casing-head, substantially as specified.
2. In a filter, the combination of an upright cylindrical casing having an outwardly-directed flange at its lower end, ahead detach ably connected to said flange, supportingdegs connected to and extending outwardly from the side of the casing and depending below the lower end of said casing so as to permit of a receptacle being placed below the same, a removable forarninated diaphragm arranged in the casing and having supports resting on the removable head, an upper foraminated diaphragm, and means for moving the upper diaphragm so as to compress ltering material between it and the lower diaphragm, substantially as specified.
3. In a filter, the combination of an upright cylindrical casing having an outwardly-directed iiange at its lower end, a head detachably connected to said flange, supporting-legs connected to the side of the casing and depending below the lower end thereof, a removable foraminated diaphragm arranged in the casing and having supports resting on the removable head, an upper foraminated diaphragm, means for moving the upper diaphragm to compress filtering material be' tween it and the lower diaphragm, a valved water-supply pipe connected with the casing adjacent to the lower end thereof, a valved eduction-pipe for water connected with the casing adjacent to the upper end thereof, and
