page_text: We DANIEL ORME and FRANCIS HEANS ORME of the firm of George Orme and
Company of the Atlas Meter Works, Oldham in the County of Lancaster, Meter
Manufacturers, do hereby declare the nature of this invention to be as follows:-
Our Invention relates to the joining or coupling together of pipes made of lead tin
or other soft metal or alloy and to the coupling of such pipes or piping with meters
cocks branches or other apparatus or appliances and particularly to the means for
effecting such junctions without the use of melted metal or solder or of heat. In our
improved coupling a nozzle made of brass or of a suitable metal or alloy is formed
with a cone and with an external screw thread and is also formed with a passage to
suit the bore of the piping. This part of the coupling may be formed upon a meter
branch or upon a cock or other body which is to be coupled to the piping.
A conical sleeve is made to pass over the first named cone so as to leave room for
the soft metal piping to come between the two cones. A nut prepared to screw upon
the said nozzle and also to engage with a collar upon the said sleeve is employed to
tighten up the joint. The sleeve being slipped on to the piping the latter is opened
out to fit upon the conical end of the nozzle. When the end of the piping is in place
the sleeve is brought up into position and the nut is tightened whereby the end of the
piping becomes tightly clamped and held between the two conical parts. When the
coupling is only required to joint or connect together the ends of two lengths of
piping two inner cones and two outer conical sleeves would be required the inner
cones being formed at each end of a screwed tubular connecting piece or being formed
upon a piece which would be separate from the screwed part or parts. In the latter
case we should use a conical thimble tapering from the centre or from a central band
to each end and we should mount a nut upon one sleeve and a screwed ring upon the
other sleeve. We are aware that the inner cone has been used without the outer
conical sleeve but in this old form of coupling the nut tended to twist the piping and
the contrivance had other disadvantages.

page_text: We DANIEL ORME and FRANCIS HEANS ORME of the firm of George Orme and
Company of the Atlas Meter Works, Oldham in the County of Lancaster Meter
Manufacturers 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 and accompanying drawings:-
Our Invention relates to the joining or coupling of pipes made of lead, tin or other
soft metal or alloy with meters, cocks, branches or other apparatus and particularly to the
means for effecting such junctions without the use of melted metal or solder or of heat.
The nature of our invention and the manner in which we carry the same into
practical effect will be clearly understood when reference is had to the accompanying
drawings, in which Fig. 1 partly in section represents a gas cock and joint. Fig. 2
being a sectional view of a connection for a gas meter these being the principal appli-
cations for which our invention was intended. In Fig. 1a is a gas cock such for
example as is used in controlling the admission of gas to meters. In the example the
cock is formed with a cone or conical nozzle band with an external screw thread c.
The said cone is formed with a passage to suit the bore of the piping which is to be
coupled to the cock. A sleeve d is made to pass over the cone 6 so as to leave room
for the soft metal piping e to come between the two cones. A portion of the bore of
the said sleeve is made conical. A nut is prepared to engage with the screw thread c
and is formed with an internal annular flange f¹ which extends behind a collar d¹
which is formed upon the sleeve. When the joint is being made the nut and the
sleeve are slipped on to the piping and the latter is expanded by means of a suitable
conical tool so as to cause the outer surface of the piping to fit the conical interior of
the sleeve and also to open out or shape the mouth of the piping so that it will fit the
cone b. When the end of the piping is in place upon the cone the sleeve is brought
up into position if not already in position upon the pipe end and the nut is brought
forward to engage with the screw c and is tightened whereby the end of the piping
becomes tightly clamped and held between the two conical parts. The bore at the
end of the piping takes the form of the exterior of the cone b so that a very tight
joint is obtained and when the piping has to be uncoupled the re-coupling can be
quickly effected the pipe end again fitting upon the cone without the necessity for the
employment of white lead or other cement or of solder or melted lead. Fig. 2 differs
only in respect of the form of the part on which the cone 6 is formed. In the
example the said part (9) is supposed to be an inlet or outlet branch for fixing to a
gas meter.
We are aware that the inner cone 6 has been used without the outer
sleeve d but in this old form of coupling the nut tended to twist the piping and the
contrivance had other disadvantages.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed we declare that what we claim is :-
The combination of the sleeve d the nut f the screw thread c and the cone 6 formed
upon a gas cock or meter branch or upon an apparatus all the parts being formed as
and for the purpose set forth and indicated.
