PROVISIONAL SPECIFICATION.
Improved Means for Connecting Pipes, especially applicable to the
Return Water Pipes of Humidifiers.
I JOHN JAMES MANN of 38 Rue du Louvre, Paris, France Electrician, do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to enable a number of branch pipes to be
conveniently connected to a main pipe, the invention being specially designed
as a system of return pipes for "Drosophores" and other similar devices for
moistening air.
For this purpose instead of using heavy and expensive wrought iron pipes for
the "main connected by T couplings to the branch pipes, I employ for the main
pipe sheet iron piping in lengths connected together by flanges or otherwise, and
at any point where a branch is to be connected thereto I clamp outside the main
pipe a pair of half rings one of which is made or provided with a tubular pap or
socket, which is made or provided with means by which the branch pipe may be
secured thereto.
Instead of the half rings a split ring or equivalent device may be employed.
I then bore through the main pipe by means of a rimer passed through the
tubular pap or socket, and I then connect the branch pipe to the latter.
If necessary a packing is placed between the socketted half ring and the main
pipe to make the joint perfectly water tight.
The above system of piping is economical and very easy to apply.

Improved Means for Connecting Pipes, especially applicable to the
Return Water Pipes of Humidifiers.
I JOHN JAMES MANN, late of 38 Rue du Louvre, now of 20 Boulevard
Poissonnière, Paris, France, Electrician, 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 object of this invention is to enable a number of branch pipes to be
conveniently connected to a main pipe, the invention being specially designed
as a system of return pipes for "Drosophores" and other similar devices for
moistening air.
For this purpose instead of using heavy and expensive wrought iron pipes for
the main connected by T couplings to the branch pipes I employ for the main
pipe sheet iron piping in lengths connected together by flanges or otherwise, and
at any point where a branch is to be connected thereto I clamp outside the main
pipe a pair of half rings oue of which is made or provided with a tubular pap or

page_text: socket, which is made or provided with means by which the branch pipe may be
secured thereto.
Instead of the half rings a split ring or equivalent device may be employed.
I then bore through the main pipe by means of a rimer passed through the
tubular pap or socket and I then connect the branch pipe to the latter.
If necessary a packing is placed between the socketted half ring and the main
pipe to make the joint perfectly water tight.
The above system of piping is economical and very easy to apply.
In order that my invention may be clearly understood I have annexed hereunto
a sheet of drawings illustrating one method of carrying my invention into
practice.
Fig. is a longitudinal section, Fig. 2 a plau view, and Fig. 3 a transverse
section of part of a galvanized sheet iron pipe a shewing my improved means
for connecting such pipe to a branch pipe; Figs. 1 and 2 show the rimer or tool
for cutting the requisite hole in the pipe a as hereafter described, and Fig. 3.
shews the branch pipe connected. The sheet iron is formed into a pipe in any
known manner; and the piping a is made in lengths (one only of which is shewn)
and may be provided with strong loose flanges a' at each end which are slipped
on the pipe and retained by turning up a slight flange at (Fig. 1) on the ends of
the sheet metal pipe itself. The lengths of the pipe a can be connected together
by these flanges a¹.
band are the two half rings before described shewn provided with lugs. The
part is provided with the tubular socket 6+ screwed internally.
The two half rings and bare firmly clamped to the sheet iron pipe a by the
bolts and nuts 63; a washer * being inserted if necessary between a and b; and
the socket receives the bush c through which passes the spindle c¹ carrying the
cutting tool at its inuer end and squared at its outer end so that it can be rotated
to cut a hole in the pipe a. The cutting apparatus e el ca may then be removed;
and a branch pipe d' fitted to the socket &, is thus connected to the pipe a see
Fig. 3.
By the use of the above described means for connecting pipes, branch pipes
such as can be connected to a main pipe a made of sheet iron zinc or other
suitable material.
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 :-
The improved means of connecting pipes whereby branch pipes may be con-
nected to a sheet iron pipe, substantially as hereinbefore described and illustrated
by the annexed drawings.
