ALBERT L. McLANE, OF LAREDO, TEXAS.
FI LT E R.
SPECIFICATION forming part of Letters Patent No. 613,170, dated October 25, 1898.
Application filed December10, 1897, Serial No. 661,371. (No model,)To al who m dt may concern.
Be it known that I, ALBERT L. MCLANE, of
Laredo, in the county of Webb and State of
Texas, have invented new and useful Im-
5 provements in Filters, of which the following
is a full, clear, and exact description.
This invention relates to filters for purify-
ing water received from ponds, reservoirs, and
the like; and the object is to provide a filter
io that shall be comparatively cheap to build
and to maintain in a clean and operative con-
dition
I will describe a filter embodying my inven-
tion and then point out the novel features in
15 the appended claims.
Reference is to be had to the accompanying
drawings, forming a part of this specification,
in which similar characters of reference indi-
cate corresponding parts in all the views.
20 Figure 1 is a section on the line 1 1 of Fig.
3 of a filter embodying my invention. Fig.
2 is a section on the line 2 2 of Fig. 3. Fig.
3 is a plan view. Fig. 4 is a sectional eleva-
tion of one of the filtering devices. Fig. 5 is
25 a vertical section at right angles to Fig. 4, and
Fig. 6 is a transverse section of one of the fil-
tering devices.
Referring to the drawings, 1 designates a
water-tight tank or basin of any suitable size,
30 and designed to be placed in the ground and
supported, if necessary, by an abutment-wall
2. Arranged in the basin is a series of filters,
each consisting of side walls 3 4 and closed at
the ends and top. The side walls are spaced
35 apart to form chambers 5, and the several
chambers of a filter have communication one
with another through spaces 6 between the
tie-bricks 7.
The whole filter is constructed of porous
40 material-such, for instance, as porous brick.
Extended from the upper chamber of each
filter is one or more pipes 8, provided with
valves, which are to be left open when the
filter is in operation, so as to allow the exit of
45 air, and thus permit the filling of the filters
with water. These pipes 8 extend above the
water-level of the basin. At the lower por-
tion and at one end each filter has a valve-
controlled pipe connection 9 with a main pipe
So 10, leading to a clear-water basin or well, and
at the other end each filter has a valve-con-trolled pipe connection 11 with a service-pipe
12, leading from a suitable head-pressure.
The space between the filters is to be suffi-
cient to allow a person to walk between them 55
in order to clear the basin or to close the
valves in any number of the pipes 9 to throw
any desired number of the filters into or out
of use. When the filter is in operation, the
valves of the several pipes 11 must be closed. 6o
They are only to be opened when it is desired
to clean out the filters by flushing. At such
time the valves in the pipes 8 are to be closed.
In operation the basin is to be filled from
any desired source and the several filters 65
entirely submerged. The water will filter
through the porous material and enter the
chambers 5, from which it will discharge
through the pipe 10.
It is obvious that by providing the valve 70
connections any number of the filters may
be cleaned while others are in operation.
Having thus described my invention, I
claim as new and desire to secure by Letters
Patent- 75
1. The combination with a basin, of a series
of filters each having porous walls and cham-
bers, a discharge-pipe with which each of the
filters has a valve-controlled connection, and
a flushing or service pipe with which each of 8o
the filters has a valve-controlled connection,
substantially as specified.
2. The combination with a basin, of a series
of chambered porous filters designed to be
submerged in the basin, an air-outlet pipe 85
leading from a chamber of each filter and ex-
tended above the water-level in the basin,
and an outlet-pipe common to all the filters,
substantially as specified.
3. The combination with a basin, of a series 90
of chambered porous filters designed to be
submerged in the basin, an air-outlet pipe
leading from the upper portion of each filter,
an outlet-pipe having a valve-controlled con-
nection with each of the filters, and a flush- 95
ing - pipe having a valve - controlled connec-
tion with each of the filters, substantially as
specified.
