TRUVIDIONAL DE MULTIO
Improved Means for Jointing Pipes, Specially Adapted for
Subaqueous use.
I, OSWALD BROWN, of 2, Victoria Mansions, in the City of Westminster,
Consulting Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved joint for pipes intended to be laid and jointed
under water, with the aid of divers, or in other positions involving difficulty in the
operation of fixing and connecting the several lengths.
In pipes as frequently constructed for subaqueous use, the spigot end of one length
fits into the faucet end of the next; the two lengths being then drawn together and
secured by means of bolts and nuts which pass through flanges or lugs formed on the
respective parts. For the bolt to be parallel with the pipe, the holes in the flanges or
lugs have to be brought opposite one another, thus almost invariably necessitating
the partial rotation of the length of pipe in course of attachment. My invention is
designed to avoid the difficulty and loss of time which this operation entails..
A joint constructed according to my improved method may be used with pipes
formed of sheet metal bent to shape and rivetted or welded longitudinally, or both
longitudinally and circumferentially; the ends of each length of pipe being formed
or furnished with solid conical rings of spigot and faucet form respectively. Behind
the conical ring upon one length of pipe is mounted a flange perforated with a
number of bolt-holes; the rear end of the conical ring upon the adjoining length
being somewhat flared so as to form a projecting rim or bead. The bolts, instead of
being made with heads in the usual way, are formed with hooked ends adapted to
engage with the rim or bead above referred to.
In laying or fixing a pipe constructed as above described, the conical ring backed
by the annular flange is placed in or over the conical ring appertaining to the next
length and having its rear end flared. The bolts are then passed through the holes
in the flange and their opposite or hooked ends are engaged with the flared rim with
which the next length of pipe is provided. The nuts are subsequently applied and
tightened.

Improved Means for Jointing Pipes, Specially Adapted for
Subaqueous use.
I, OSWALD BROWN, of 2, Victoria Mansions, in the City of Westminster,
Consulting 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 :--
This invention relates to an improved joint for pipes intended to be laid and jointed
under water with the aid of divers, or in other positions involving difficulty in the
operation of fixing and connecting the several lengths.
In pipes as frequently constructed for subaqueous use, the spigot end of one
length fits into the faucet end of the next; the two lengths being then drawn
together and secured by means of bolts and nuts which pass through flanges or lugs
formed on the respective parts. For the bolts to be parallel with the pipe, the
holes in the flanges or lugs have to be brought opposite one another, thus almost

invariably necessitating the partial rotation of the length of pipe in course of
My invention is designed to avoid the difficulty and loss of time which
this operation entails.
In the accompanying drawings, Fig. 1 shews in side elevation two pipes jointed
according to my improved method; Fig. 2 shewing in side elevation portions of a
pipe having spigot and faucet ends adapted for use in effecting the improved joint.
Fig. 3 is an enlarged view partly in section and partly in side elevation illustrating
in greater detail the means employed for holding contiguous lengths of pipe
together.
A joint constructed according to my improved method may be used. with pipes
formed of sheet metal bent to shape and rivetted or welded longitudinally, as in
Fig. 1, or both longitudinally and circumferentially, as in Fig. 2; the ends of each
length of pipe being formed or furnished with solid conical rings A and A¹ of spigot
and faucet form respectively. Behind the conical ring A¹ upon one length of pipe is
mounted a flange B perforated with a number of bolt-holes; the rear end of the
conical ring A upon the adjoining length being flared to form a projecting rim or
bead a.
The bolts C, instead of being made with heads in the usual way, are formed
with hooked ends c adapted to engage with the rim or bead a.
In laying or fixing a pipe constructed as above described, the conical ring A¹
appertaining to the next length is placed over the conical ring A. The bolts Care
then passed through the holes in the flange B and their opposite or hooked ends c
are engaged with the flared rim a. The nuts are subsequently applied and
tightened.
It will be obvious that the positions of the flange B and flared rim a may be
transposed, the former being mounted on the spigot end of a pipe and the latter
being formed on the back end of the ring A' attached to the faucet end of the pipe
to be connected.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I claim :-
1. The improved means for jointing pipes substantially as herein described,
whereby, in fixing and connecting the several lengths together, the necessity for
rotating the pipe-flange through which the holding bolts pass is avoided.
2. In jointing pipes for subaqueous use and otherwise, the employment of a flange
on one length of pipe, a flared rim on the adjacent end of the next length and
hook-bolts which pass through the flange and engage the edge of the flared rim.
