not be fouled but would be for all practical purposes clean, as it would never have

in Connection with Street Gullies.
I, JOHN HORACE RHODES, of Park Square, Leeds, in the county of York, Civil
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
"
The benefits to be derived by keeping storm water out of sewers are well known
where the sewage has to undergo treatment. Further, in certain cases, storm-water
ought not to be diverted from channels where it is valuable and has hitherto run.
The well known plan of separating turbid water by means of a "leaping" or
separating weir "is not adaptable for the purpose of separating storm-water from
the slower-flowing sewage at a street gulley because of the costliness of specially
building and arranging such weirs at each of these many points.
The object of my invention is to manufacture a separating appliance properly
formed & proportioned, and, where required, easily regulated, so as to be available
in great numbers, at a low price, not here and there in a system only, but at, and
connected with, if necessary, every street gulley. One great advantage of such an
appliance fitted as far as possible in connection with every gulley would be that the
storm-water would not be fouled but would be for all practical purposes clean, as it
would never have been admitted into the sewers.
1 carry out my object as follows-and in order to fully explain my invention I
have annexed a drawing. The same letters refer to the same parts in all the figures.
Figs. 1 to 7 are Sectional Elevations—and figs. 8 & 9 are plan views. I arrange my
separators so that they or their main bodies can be made in one piece, or practically so,
be they of earthenware or metal,-ready for burying in their trenches. The body, A
should be rectangular but the branches, to and from, should have terminals suited
to the connecting pipes & these are therefore best made circular. The incoming
spout, B, should always be rectangular. or at least equivalently horizontal in cross-
section (See fig. 6) and should be supplied, if required, with a projecting lip B',
shown in dots in fig. 1, to assist the storm water & direct it in its leap to the other
side. Here at Ca suitable outward branch,-arranged at the requisite lower level,―
leads it away as required, say, where necessary, to any desired surface-water channel.
The slower-flowing sewage being unable to take the leap falls into the lower part of
the separator and is led away at Ď down to the sewer. In fig. 2 the sewage is shown
falling quietly down, and in fig. 1 the Storm-water is shown taking the leap. A
suitable lid, E, may cover the top.
The distance to be leaped and the force of the flowing current must be taken into
consideration in arranging the shape or configuration of a separator that is capable of
no adjustment. But such an adjustment may easily be arranged for :-first by
permitting the incoming pipe to be loose so that it may be fixed, when being laid by
the workman, further in or out, as the case may be; See fig. 2 where B¹, is the loose

page_text: incoming pipe, or, second, the sill on to or over which the water leaps may be made
interchangable so that a higher or lower sill may be arranged at any time-even after
the separator is fixed; See fig. 3 where (" represents such a sill piece which is fitted
in grooves prepared for it.
By thus making my separator in one piece, or, at any rate its main body in one
self contained piece, with its entrances and exists all arranged, I avoid calling into
requisition any skilled labour in afterwards fixing it, further than that of the pipe-
layer whose only directions need be as to the distance the entrance-spout B₁, if
separate, is to be admitted into the interior; or as to the height of the interchangable
sill, C is to be first tried.
These latter in order to fix the degree of storm-water to be caught.
Having described the nature of my invention; I need only add that a variety of
details may be arranged in and around my separator, but I prefer a rectangular body,
with a flat edge, of any desired breadth, at B or B' for the water to leap from, as
this shape would best deal with the maximum quantity of slow-flowing sewage and
give the cleanest leap for storm-water when in quantities.
Any suitable angle may he used for leading in and out. The separator may, of
course, be made in one piece with the gulley, after the manner shown in fig. 4, where
G.is the gulley, or, arranged side by side with it after the manner shown in fig. 5.
Fig. 6 is a section showing the horizontal edge which should preferably be used at
B or B for the incoming liquid.
Fig. 7 shows a mode of arranging an interchangable leaping edge B¹, and
figs. 8 & 9 are corresponding plan views showing the way in which the proportions
of these pieces may be varied-still letting them rest on the ledge, 6, and abut
against the end stop, b'.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
(1) The manufacture of metal or earthenware vessels for separating storm-water
from sewage (in connection with street gullies) the bodies of which are made in one
piece, or practically so, after the manner described herein and shown on the drawing.
(2) The manufacture of metal or earthenware vessels for separating storm-water
from sewage (in connection with street gullies) the bodies of which are in one piece
or practically so, fitted. with interchangable Sill pieces, or interchangable leaping
edges for the purposes of regulation, after the manner described herein and shown on
the drawing.
