"IMPROVEMENTS IN DRAIN PIPES"
My Invention has for its object an improved construction of drain pipes whereby
they are rendered more easily accessible for the inspection or clearing of the drain
or in case of breakage, than is the case with the present system of pipes.
In
It consists in forming both ends of each length of drain pipe with a half flange
or faucet in lieu of with a whole flange or faucet at one end as at present.
arranging a series of pipes on this principle each alternate pipe is placed against the
intermediate pipe with its half flanges or faucets uppermost whilst the half flanges
or faucets of the intermediate pipe will be lowermost.
By this simple means the alternate pipe at any part of the drain can be directly
lifted out and replaced or renewed without any difficulty.
The joints of the various lengths of pipe may be made in the usual way and my
Invention is equally applicable to pipes composed of earthenware, iron, or any other
inaterial.

IMPROVEMENTS IN DRAIN PIPES
"
My Invention has for its object an improved construction of drain pipes whereby
they are rendered more easily accessible for the inspection or clearing of the drain
or in case of breakage than is the case with the present system of pipes
And in order that my Invention may he well understood I shall now proceed
particularly to describe the same, reference being made to the accompanying sheet
of drawings, like letters of reference indicating corresponding parts in the respective
figures
Figure 1 is a longitudinal section of a series of drain pipes constructed and
arranged on the principle of my invention, and Figure 2 a perspective side view
thereof (partly broken away)
My Invention consists in forming both ends of each length of drain pipe A. A'.
with a half flange or faucet a or bin lieu of with a whole flange or faucet at one
end as at present In arranging a series of pipes on this principle, each alternate
pipe A is placed against the intermediate pipes A' with its half flanges or faucets a
uppermost as shewn, whilst the half flanges or faucets 6 of the intermediate
pipes A¹ will be lowermost By this simple means the alternate pipe A at any part
of the drain can be directly lifted out and replaced or renewed without any
difficulty The joints c of the various lengths of pipe A. A'. may be made in the
usual way, and my Invention is equally applicable to pipes composed of earthen-
ware, iron; or any other material
Having now described and particularly ascertained the nature of my said
Invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider novel and original and
therefore claim as the Invention secured to me by the herein before in part recited
Letters Patent, is :-
Forming each end of a drain pipe with a half flange or faucet, in lieu of with a
whole flange or faucet at one end only, substantially as and for the purpose
hereinbefore described and illustrated on the accompanying drawing
In Witness Whereof I the said Francis Harry Noott have hereunto set my
hand and seal this sixteenth day of March in the year of Our Lord One
