COMPLETE SPECIFICATION,
A New and Improved Detachable Joint for Water Pipes, Soil Pipes,
Sewers, and the like.
I, NIMROD SIMMONS B.Sc., of 8 Glendale Clifton, in the City and County of
Bristol, Civil 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:-
A new and improved detachable pipe joint or connection, and forming a
watertight joint at the butted ends of socketless pipes, being separate therefrom.
The joint consists of loose cups or half sockets provided with lugs, and bolts
engaging with them compress the cups together upon packing rings of special form,
and upon a central ferrule also of special shape.
If reference be had to the accompanying drawings, Fig. 1 is a section through
the joint when in position at the butted ends of piping D. D. A. A. are the cups,
B. the central ferrule or ring with edges of taper or wedge shape section as
shown.
C. C. are jointing or packing rings of U section and are made of india-rubber,
asbestos, leather, lead or any other elastic material or pliable alloy.
The cups and ferrule are made of cast iron, cast steel, or brass: or of forged iron
or steel as may be deemed desirable.
Fig. 2 is an elevation of the joint viewed endwise, and shows the lugs F,
compressing bolts E and radial set pins P which are used to steady heavy joints in
position.
Fig. 3 is a side elevation of the joint in position on pipes D. D, and clearly
shows the lugs F. F. compressing bolts E. the ferrule B. and cups A. A.
The joint is used by placing the several parts upon the pipes in the order shown
in Fig. 1, and compressing the whole by means of the bolts and nuts E, engaging
with lugs F, whereby the packing rings are expanded into the cups A. A. by the
taper edges of the ferrule as shown in the drawing.
Figs. 4. 5. 6. 8. represent an alternative arrangement of the joint, the parts being
substantially as before described. The packing rings C. C. are here placed inside
the ferrule B, and are expanded into it and upon the pipes D. D. by the taper or
wedge shaped circular edges formed on the cups A. A.
Figs. 7. 8 are enlarged sections of both arrangements as described, and similar
letters of reference indicate the various parts as before set forth.
The improved joint described may be used upon any kind of pipe whatsoever,
but generally upon water pipes, soil pipes, steam pipes, sewers and the like.
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. The combination of cups with lugs engaging with compressing bolts, and
inserted between the cups a ferrule or ring having wedge shaped edges as shown in
section, and these latter for the purpose of expanding packing rings of the form
shown, into the recesses of the cups also as shown, and upon the pipes to be
jointed.
2. I claim for the packing rings as described and of U shape in section for the
reception of the taper edges of the ferrule as described, and made of india-rubber,
asbestos, leather, or any elastic substance and also of lead or other pliable metal
or alloy.

page_text: 3. I claim for the alternative arrangement of the improved joint and its parts as
shown in Figs. 4. 8. where the packing rings may be formed as before described,
and placed back to back, or formed in one piece as shown.
Dated this 12th day of April 1894.
