PROVISIONAL SPECIFICATION.
Improvements in Connecting Bends of Drain and other Pipes.
FREDERICK CHARLES LYNDE 25 Cross Street Manchester, Civil Engineer, do
hereby declare the nature of this invention to be as follows:-
My invention consists in making a new kind of rest bend or connecting bend for
drain and other pipes.
Instead of the usual form of bend which is of circular cross section throughout
I make the surface which receives the impact of the drainage of a flattened curved
form so as to form a deflecting surface and thereby cause the drainage or water to
be projected in a new direction and down the deviating pipe. My object being to
take full advantage of the flushing power of the drainage or water.
To compensate for the contracted size of the bend caused by the deflecting
surface I make the portion of the bend opposite to this part of an arched form so
as to increase the cross sectional area.
I may form a base upon which the bend shall rest and a hand hole ou its upper
side or either or a testing junction in connection therewith furnished with a
stopper.

COMPLETE SPECIFICATION.
Improvements in Connecting Bends of Drain and other Pipes.
FREDERICK CHARLES LYNDE 25 Cross Street, Manchester, 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:—
My invention consists in making a new kind of rest bend or connecting bend for
drain and other pipes.
Instead of the usual form of bends which (see Figures 1 and 2) do not deflect
the water striking the inner surfaces of the bend directly down the drain as shewn
by the arrows, I make the longitudinal section of that portion which receives the
impact of the water of flattened curved form either straight concave or convex see
Figures 3 4 and 5. or shapes approximate to the same for the purpose of deflecting
the water or other matter down the drain in the desired direction as shewn by the
dotted arrows on Figure 3.
The forms and position of the deflecting surface or surfaces as seen in longitudinal
section are the chief features of my invention.
In order however that this flattening of the curve of the inside of the bend may
not diminish the area of the pipe it is preferable that at the narrowest part of the
bend, the pipe shall not be circular in cross section, and it is obvious that there
may be many variations of form in the transverse section of the deflecting surface
which will all cause the water or other matter to be deflected in the direction
required, with the object of taking full advantage of its flushing power without
diminishing the area of the pipe at the bend, soine of these are exhibited in the
sections marked Figures 6. 7. 8. 9. 10 and 11 and shewn by full and dotted lines
and each one is taken to be a form of section through the line A. B. Figure 3.

page_text: I may fix the base of the bend upon its side, so that the peņu may
the course of a drain, so as to divert the water or other matter in another direction
for which purpose the deflecting surface or surfaces will vary with the angle of
the direction required.
For such an adaptation the bend might be used without the base.
Having now particularly described & ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
1. The use and manufacture of a bend or bends having the longitudinal section
formed by a flattened curve or straight line substantially as described hereinbefore
and shewn in Figures 3. 4. and 5 of the drawings annexed.
2. The use and manufacture of a bend or bends having the interior surface,
which receives the impact of the water or other matter so formed that the water
or other matter is deflected in the desired direction in such a manner as to take
full advantage of the accumulated force, substantially as in the manner described
and illustrated herein.
3. The use and manufacture of a bend or bends having their transverse and
longitudinal sections of the portions which receive the impact of the water or other
matter of such forms as will project the water or other matter in the desired
direction substantially as and for the purposes described.
4. The use and manufacture of a bend or bends in which the centre lines of th
inlet end and the outlet end are at a right angle or obtuse angle to each other, i
combination with the flattened curve or straight line representing the deflectin
surface in the interior of the bend, as substantially shewn in Figs. 3. 4 and 5 an
for the purpose described.
