COMPLETE SPECIFICATION.
Improvements in Closet and Sewage Waste-pipes and in the Method
of connecting same.
I, ANTON HEINRICH DICKEL of Remscheid, in the Kingdom of Prussia,
Builder, 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 :-
This invention relates to improvements in closet and sewage waste-pipes, and in
the method of connecting the same together.
It has always been found a great defect in the usual system of waste-pipes, that
when any stoppage in the same occurs in the house the use of said system is
interrupted for a longer or shorter period, and it is often impossible either to
locate the stoppage, or at least to remove the obstruction without serious damage to
the pipes.
Now I avoid the above defects by the use of telescopic pipes attached together
in the manner hereafter described. Should a stoppage occur, the workman need
only loosen the fastenings and slide one pipe into the other sufficiently to enable
him to examine the interior.
Fig. 1 of the accompanying drawings shows my new system of pipes closed,
Fig. 2 the same opened, and
Fig. 3 shows a modification.
A and B are telescopic pipes, provided at their upper ends either with slightly
enlarged heads or with iron rings. The former are usually cast or forged on iron
pipes, and serve as the seat of two vertical bolts, either provided with a screw
thread or with a spiral spring. To close or open the pipes the bolts can be
Bcrewed up or down by means of the nuts or pushed down by compressing the
springs.
Should the pipes be not of iron, then just below their top orifices iron rings are
set, the upper one being provided with a hinged two-armed latch. This latch is
attached to the iron ring of the lower pipe by means of a bolt as shown in Fig. 3.
This bolt can be provided with a hole at one end and through which is passed a
hanging lock.
To open the pipes for the purpose of examining the same, it is only necessary to
either turn the nuts of both bolts simultaneously with suitable keys, Fig. 1, or to
compress the springs, Fig. 2, or to open the lock and throw out the bolt, Fig. 3.
In all three cases the upper pipe is caused to slide into the lower one, and in this
way, the pipe system can be opened at any point in the house, and carefully
examined and repaired.
On the work being finished, the nuts are screwed back, causing the pipes to again
close, or the lower pipe is drawn up by hand, and the latch arrangement attached
in place the whole system being then again in working order.
Having now particularly described and 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. Closet and sewage waste-pipes made to telescope into each other for the
purpose of enabling an examination of or repairs to the same to be effected when
necessary, said pipes being held in position for use by means of screw bolts or bolts
provided with spiral springs, substantially as and for the purpose herein described,
with reference to the accompanying drawing.
2. The modification of Claim 1 consisting in the use of a latch hinged to the
upper pipe and attached to the lower pipe by means of a bolt, which latter can be

page_text: secured by a hanging lock, substantially as and for the purpose herein described
with reference to the accompanying drawing.
Dated this 22nd day of March 1893.
