I, JOHN MARSON LAMB of 119 Finchley Road South Hampstead in the County
of Middlesex Engineer do hereby declare the nature of this invention to be as
follows:--
This Invention consists in making joints and connections on Lead, iron, stoneware
and other pipes and the construction of pipes for the same, by which a perfect sound
and strong joint can be made by cement. For making the joints on lead pipe I
construct a lead ring or collar to form a cushion the inside of which I make of the
same bore as the internal size of the pipe to be united and the outside is formed to
represent two triangles of any suitable plane or angle. I then dress out a correspond-
ing flange on the ends of the pipes to be united so as to fit on the outside of the lead
cushion. These pipes can either be united to the cushion by solder, or by a wire tied
round each pipe and the two twisted together to hold them in position. I also make
two metal cases to fit the outside of the pipes. These cases are made in the curvilinear
form to represent the O. G. line (although I do not bind myself to any particular
shape). One end fits close to the pipe the other end is of larger dimensions. These
two metal cases are sliped on the pipes before they are flanged out. After the pipes are
fixed to the cushions the wide end of the cases are brought together opposite the
V portion of the cushion and temporarily fixed in position. The top case is made with
a hole which is temporarily surrounded with some plastic material through which I
pour melted sulphur or other cement which when set forms a perfect rigid joint round
the pipe and between the outer caseing. The irregular form of the cushion and the
case creates a perfect lock on the pipes joined by the cement. I can also make these
joints by having the cushion made hollow in the two opposite planes of the triangles
and made in two half circles instead of the perfect ring so that when the pipes are
flanged out the cushions fit outside the pipes and can either be tied together round
the V portion with wire or soldered together at the joint which will then firmly hold
the two pipes together like a clamp with the flanges resting on the inside of the
cushion. I use the outside cases and make the joint with cement as described. In
making branch joints, I can make the branch pipe cast on a. short piece of straight
1 Unice R71

page_text: pipe with either a single or double triangle projection on each end to form the cushion
or a plain branch pipe can be fitted with loose cushions, and the outer metal caseing
of sufficient length to cover the branch and the two cushions. This caseing can be
made of any suitable shape to meet the requirements of one or more branches. In
making these joints on iron pipe, I use the same external caseing, and unite by the
same method, and can use the same cushions described for the lead pipe, but I can
also make a cushion with the outside planes of the triangles elongated to fit outside of
the iron pipe which pipe when specially made is formed with a partial rim on the
edge or with a sunken groove when the cushion is cast in the ring form. I dress the
elongated ends over the rims of the pipes or into the grooves which fixes them
together when the cushion is cast in two halves. I fix them together by a wire round
the V of the cushion then draw the two outer caseings together and fix with cement.
The caseings for this pipe I make with slots to correspond with the partial rim on the
pipe to enable it to be readily sliped on the pipe. In making these joints on ordinary
plain iron pipe, I can use any of the cushions herein-described but for the purpose
of fixing I cast a short piece of pipe with a rim or flange to fit the cushion which can
be wedged on to the pipe for the purpose of making a sound fixing and supporting
the pipe either inside or outside of the cushions previously to fixing the caseing with
cement. I do not bind myself to any cement for the filling medium-As Alum,
Sulphur, Bituminous Compounds, Portland Cement, or Molten Metal or any other
suitable material can be used. The cushions can also be made of any suitable material
for the purpose required. One of the outer caseings at the uniting edge can be made
with a narrow straight or hollow flange into which the opposite half fits to give an
additional strength to the cement joint. I can also make this joint without the cushion
by dressing out a flange on the ends of the pipes then tieing them together and fixing
by means of the caseing and cement. But I prefer to use the cushion as thereby I
get a much stronger and more reliable joint These joints can be made to suit
either round, square, or any other shape pipe and of any design, or configuration to
suit architectural construction.

I JOHN MARSON LAMB, of 119 Finchley Road South Hampstead in the County of
Middlesex, 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 consists in making joints and connections on lead, iron, stoneware,
and other pipes by which a perfect sound joint can be made by cement or other suitable
material. The pipes to be joined I connect either by a cushion in one or more pieces
fitting between and internally or externally of the two edges of the pipes to be joined,
and fixed by a wire tie or wedge or screwed clip, or otherwise, I also make two metal
cases to fit the outside of the pipe in the curvilinear or other suitable shape, one end
to fit close on the pipe and the other end of suitable dimensions in proportion to the
required body of cement necessary to make a strong joint. These metal cases are
slipped on the pipe before they are flanged out to fit on, or in the cushion, the pipes
are then secured to the cushion and the two cases are brought together centrally. The
top case is made with a hole which is temporarily surrounded with some plastic
material through which the cement or other suitable filling material is poured. The
irregular form of the exterior of the cushion and the case creates a perfect lock on
the pipes joined by the cement. The accompanying drawings will serve to more fully
explain my invention. Fig. 1 an elevation of a pipe joint. a. a. being the two pipes
joined. b. b. the metal cases for holding the cement. E the hole in top case through
which the cement is poured. Fig. 2. is a section shewing the joint on lead pipe by

is a section shewing the method of fixing a plain ended iron pipe a¹ and a lead pipe. a.
into the cushion c. which is made of iron. or brass, or other firm metal. The cushion
is fixed by any of the described ways and the iron pipe made fast by wedges or
set screws or otherwise. Fig. 8. represents the method of making a branch
joint or connection G made in the cushion piece c¹ and fixed on the lead pipe. a. by
the tie wires d. d. or otherwise. In making the junction on iron pipe Fig. 5. the
branch or branches can be made in a complete cushion c³ and fixed by hammering the
ends down over the rim. Or the branches can be made separate, and fixed by a
separate cushion on each end and either covered by two pair of casings b. b. as shewn
in Fig. 1. or by one pair of casings b. b. Fig. 8. Thesese joints can be made on pipes

page_text: of any material and of any shape and the filling or jointing medium of any suitable
material that can be rendered fluid and will again solidify.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is
1st. The construction of an internal cushion for the reception of the pipes to be
joined which are fixed thereto by wire ties or solder or otherwise and surrounded by
two separate metal cases with a hole in one and the filling up of the space between
the case and the cushion with cement as herein shown and described.
2. The construction of the external cushion in two or more pieces with an internal
channel in the opposite planes for the reception of the lead or other pipes inside of
the cushion and united to the pipes by a tie wire. or screw clip, or wedge substantially
as described in reference to Figs. 3. 4. and 6 of the annexed drawing.
3. The construction of the cushion in a complete form for dressing on to the pipe
as shewn at C³ Fig. 5 and for the purpose of connecting lead and iron, stoneware or
other materials as shewn in Fig. 7 of the annexed drawing by means of the cushion
in two or more pieces substantially as described and for the purpose set forth.
4. The construction of branch joints as described in Fig. 8 in two or more portions
of the cushion secured to the pipes by wire ties, or screw clips, or wedges, and also
the complete cushion as herein-before described and set forth.
