page_text: PROVISIONAL SPECIFICATION left by William Edward Newton at
the Office of the Commissioners of Patents, with his Petition, on
the 20th June 1872.-A communication from abroad by Nathan
Thompson, of Brooklyn, in the State of New York, United States
of America.
I, WILLIAM.EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of the said Invention for "IMPROVEMENTS. IN STENCH TRAPS, AND
IN APPARATUS FOR MAKING THE SAME AND OTHER CURVED OR PARTLY CURVED
ARTICLES," to be as follows:-
The first part of the Invention consists in a trap made of lead or other
like pipe in entire or closed sections peripherically with its joints, which.
unite the sections, arranged transversely to the pipe in the bent portions.
of the trap, and formed by the sections fitting at their ends, the one
within the other, and afterwards uniting them by soldering. A trap
thus constructed is at once strong, easily put together, presents a
limited joint exposure, and admits of being variously twisted or shaped
•

connections.
The second part of the Invention relates to apparatus for making
traps constructed as herein-before described, also for making other
curved or partly curved pipes and articles from various materials or
substances in moulds by means of cores, about or around which latter
the substance to be worked is run or placed while in a fluid or plastic
state, and afterwards allowed to solidify in the moulds.
This part of the Invention consists in a novel apparatus or com-
bination of devices for thus making stench or fluid traps, and other
curved or partly curved pipe or articles, the same comprising mainly
a curved core or cores pivoted or hinged so as to be capable of being
swung to or from their places in combination with a mould or moulds
of corresponding configuration within and out of which the cores are
adjusted or swung to form the curved or partly curved pipe or article, and
to admit of its removal on opening the moulds. These cores are pivoted
or hinged to the moulds themselves, and the moulds made to open and
close with a sliding motion on rods or guides in directions parallel with
the axis of the 'core's pivots. When making partly curved pipe, then
additional straight cores are introduced within the moulds to form a
junction with the inner ends of the curved cores so as to make an article
or pipe which is straight for a portion of its length but curved at its end.
The moulds and cores may be made of any suitable material that will
allow of the solidifying of the substance to be made into pipe or other
required article within and about them, and of the removal of the cores
and moulds from the article or pipe. By making curved or partly
curved articles or pipes, in this manner much labour is saved and better.
or more regular work is produced with fewer joints for a given length of
article.or.pipe made up of a series of sections; or with the joints better
arranged.
ADO
The Invention will be found particularly advantageous in plumbers'
work, as in the case of traps-used for sinks, waterclosets, and other
purposes....
