Complate Specification Left, 24th Aug., 1891-Accepted, 3rd Oct., 1891
PROVISIONAL SPECIFICATION.
Improved Apparatus for Filtering Rain Water.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Edwin Detwiler, and J. E. Swartzbaugh, both
of Dayton, Ohio, U.S.A. Gentlemen,) to be as follows:-
This invention relates to an improved apparatus for filtering rain water during
its passage through the leaders to the cistern and other receptacles.
The construction of the apparatus comprises a preferably circular cylinder made
of sheet metal, and of convenient length. This cylinder is closed at its lower end,
and has a flange around its top edge which leaves a circular opening in the upper
end. This opening is fitted with a circular lid. A partition is arranged midway
the length of the cylinder which has a central circular opening, and divides the
cylinder into two compartments, an upper and lower one respectively. A pipe
enters through the flange around the top of the cylinder and extends through into
the lower compartment. A similar pipe enters bottom of the cylinder, and extends
into the top compartment. A reticulated screen is arranged in the upper com-
partment, and is of the same diameter as the openings in the top and the partition;
and within this screen are two other screens, each one being of finer mesh than
the other. Below these screens, and depending from the partition into the lower
compartment is another screen which also contains an inner screen of coarser mesh
than the outer one, but both of them are of coarser mesh than the top one. These
screens are so arranged that they can be removed when necessary for cleaning.
The water from the leads passes down the pipe which extends from the top
into the lower compartment, and passing upwards through the screens enters the
top compartment, where it escapes through the other pipe to the cistern or other
receptacle.
Dated this 22nd dow of November 1890.

COMPLETE SPECIFICATION.
Improved Apparatus for Filtering Rain Water.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a communi-
cation to me from abroad by Edwin Detwiler, and J. E. Swartzbaugh, both of
Dayton, Ohio, U.S.A. Gentlemen,) and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to certain new and useful improvements in filters designed
more especially for use for preventing the leaves, dirt, and other foreign sub-
stances from entering a cistern or other receptacle through the leaders of the
rain-water spout. It is designed to be fixed in any suitable way to the side of
the house or in any other desired position where it will have communication with
the down-spout, and may be thus secured in any well-known way, such as by lugs
and encircling bands or any other provisions suited to the location.
The object of the invention is to provide a simple, cheap, and efficient device
of this character by which the water will be thoroughly filtered in its passage
through the device, a series of screens of varying mesh being provided and all

page_text: made removable, suitable provisions being made for the removal of the débris as
it accumulates.
Other objects and advantages of the invention will appear in the following
description, and the novel features thereof will be particularly pointed out in the
claims.
The invention is clearly illustrated in the accompanying drawing, which, with
the letters of reference marked thereon, forms a part of this Specification, and
which is a vertical section through my improved filter.
Referring now to the details of the drawing by letter, A designates a chamber
or receptacle of any suitable material-such as galvanized iron, tin, or other
material suited to the purpose-and of any preferred form, preferably, however,
cylindrical. It is divided horizontally by the partition A'.
C is an inlet-pipe extending through the top and also through said partition
and rigidly held in place in any preferred manner. It is designed to receive or
be connected with a down-spout, (not shown,) and, if desired, more than one inlet-.
pipe may be provided, so as to receive the water from more than one down-spout
or branches.
D is a pipe extending through the partition A' and through the bottom of the
chamber A, extending, preferably, a short distance above said partition, as shown.
This pipe is designed to be connected with or to lead to the cistern or other
receptacle for the filtered water.
The horizontal partition A¹ has a central opening to receive the filtering devices.
They consist of the basket-shaped receptacle E, of some reticulated medium, as
wire-gauze of coarse mesh, and has extending upward within the same a conical
portion E of the same mesh.
F is a conical screen of reticulated material of finer mesh than that of E and E',
and is carried by an encircling band F, substantially Z-shaped in cross-section,
as shown in the drawing, the horizontal portion of which rests upon the partition A',
surrounding the opening therein, and is designed to thus support the filtering
devices.
Secured to the cone F and arranged within the same near its base is the convex
cap or cover G, whose mesh is the same as that of the parts E and E¹. These
parts E, E, F, and G are held together detachably by means of the vertical
rod H, which passes through the apex of the two cones and at its upper end
provided with a loop or handle and at its lower end passed through spider-
arms ', attached to the base of the cone E', and beneath the same receiving a
nut, engaging the screw-threaded portion of said rod. These parts are thus
held together, so as to all be removed together, if desired, but allowing of
their ready separation for repairs, the replacing of any one part, or for any other
purpose.
I is a cylinder of reticulated medium of very fine mesh removably inserted
within the upper chamber of the receptacle A, with its lower end fitted within
and held by the vertical upper portion of the ring F. It surrounds the cone F,
and at its upper end is provided with a strengthening-band a.
J is a cover or cap fitted over an opening in the top of the receptacle A, and is
provided with depending and annular flanges, as shown, to keep the same in place
and to steady the cylinder 1, as shown. It may be locked in place in any suitable
mauner.
In the bottom of the chamber A there is an outlet-aperture communicating
with the discharge-neck b, and this aperture is normally closed by the valve c
carried by the rod d, which extends upwardly to the top of the chamber A, and
near its upper end is provided with a notch e, having an inclined approach, as
shown in dotted lines, and adapted to engage a stop f on the top of the
-chamber A and hold the valve elevated when it is desired to remove the sediment
from the chamber.
The operation is simple and will be readily understood. The receptacle E is
designed to be filled with charcoal or some analogous material, and as the water

page_text: flows into the chamber A. from the down-spout through the pipe C it first passes
through the reticulated medium of the chamber E and cone E'; thence through
the cap G, then the cone F, and finally through the fine screen I and out through
the pipe D to the cistern or other receptacle. The course of the water is indicated
by arrows. When the valve c is raised, water may be admitted through the pipe
to wash the sediment through the outlet b. When the cistern is full, the raising
of the valve c permits the water entering through the pipe C to flow off through
the outlet to the sewer or other place of deposit.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The combination, with the chamber having inlet and outlet pipes and
horizontal partition, of the reticulated receptacle below the partition with interior
conical screen and the screens of finer mesh above the partition, substantially as
specified.
2. The combination, with the chamber having inlet and outlet pipes and
horizontal partition, of the detachably-connected screens E, E', and F, the latter
arranged above the partition and the two former below the partition, and the
reticulated cylinder I, of finer mesh, above the partition and enclosing the screen F,
substantially as specified.
3. The combination, with the chamber having horizontal partition and inlet
and outlet pipes, of the connected screens E and F, of different mesh, the cone E',
extending within the screen E, the convex cap G within the cone F, and the
reticulated cylinder I, of finer mesh, surrounding the conc F, substantially as
specified.
4. The combination, with the chamber having inlet and outlet pipes and valve-
controlled outlet, of the detachable-connected screen E and cone F, of different
mesh, the cone E within the screen E, the convex cap G within the cone F,
near its base, the cylinder I, of finer mesh, inclosing the cone F, and the ring F¹,
supporting all of said screens, substantially as shown and described.
Dated this 22nd day of August 1891.
