PROVISIONAL SPECIFICATION
Improvements in and relating to Rain Water and other Pipes.
I, JOHN BELL MILLAR, Iron Founder, of the Sun Foundry, Glasgow, Lanark-
shire, do hereby declare the nature of my invention to be as follows:-
-
This invention has reference to and comprises improved constructions of and
fittings for rain water, soil, and other pipes, where faucet and spigot joints are used,
made of cast or malleable iron, fire-clay or other suitable material, and specially
applicable to the rain rhone pipes of buildings, all with the object of enabling the
individual pipes to be separately removed for repair or being cleaned out, and thus
dispense with the necessity of requiring to remove all the pipes when any one of
them gets choked or broken, as has been necessary heretofore.
According to my invention the faucet end parts of the pipes are made longer
than usual, preferably about double the usual length, and have cast or fitted on
their inner surface, preferably near the centre of their length, two or more sectional
or segmental projections or supporting surfaces opposite each other, and the
extreme ends of the outer surfaces of the spigot ends are formed with corre-
sponding segmental projections to bear and rest on those of the faucet ends
when jointing or connecting the pipes, and so that when any pipe of a set is
desired to be removed for cleaning out or repair, by simply turning it round by
hand, these segmental projections on the faucet and spigot ends pass one another
at the spaces between the segments, and the spigot end falls to the bottom of
the elongated faucet end, which clears its faucet from the pipe at the other end
and enables it to be at once lifted out, and be replaced again by simply turning
it round to bring the projections on the spigot end to bear on those on the
faucet end. To enable these pipes to be portably secured to the wall of a
building or other place where they are to be used, and in their proper position
over their said segmental projections, they are by a further improvement secured
round their faucet ends by special car or annular bands, hinged, jointed, or so
connected that they can be easily removed or opened up when a pipe is to be
lifted away
These bands would consist of circular square or other forms of
straps or rings having the one half-or-part secured to the wall-of-the-building
or other place where they are to be used by "butt joints, or by projecting
lugs or flanges and bolts or screws driven into the wall. And the other annular
half or segment of the band is connected at its ends to the stationary part,
either by having one a fixed oscillating or hinged joint, and the other a portable
or removable pin or other equivalent joint, or both joints may be so fitted as
These
to remove the outer gripping segment when a pipe is to be lifted out.
joints would consist of overlapping eyes or lugs, or projecting flanges on the
ends of the portable and stationary parts of the bands secured together by
removable pins or bolts, or by folding shackles, or when flanged joints are used
one of the flanges could be formed with a slot or hole and the pin given a half
turn round to lock or unlock the T head part. Or one of the parts would be
formed with two projecting eyes as a fork, and the other part have a projecting
centre eye part to enter between these, and the whole be secured together by a
removable transverse pin like a hinge joint. Or the one part would overlap or
slide over or into the other and be formed with a square or rectangular slotted
hole for a square or rectangular or T headed pin to work into, the turning of
which a little round by a handle outside would secure both parts together, and
the one part could be formed with a recess for the head of the pin to work
round within. Or the overlapping parts would be formed with recessed segmental
grooves and stops and be secured together by a movable arm or crosshead on the
22

and abutting against the stops in their locked position and turned by a round
or other head outside. Or a recessed segmental annular groove would be formed
in the head which would work against a projecting stop or stops on one of the
parts to retain them together.

COMPLETE SPECIFICATION.
Improvements in and relating to Rain Water and other Pipes.
I, JOHN BELL MILLAR, Iron Founder, of the Sun Foundry, Glasgow, Lanark-
shire, do hereby declare the nature of my said invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement in writing, reference being had to the accompanying sheet.
of drawings, and to the letters and figures marked thereon, that is to say:-
My invention has reference to and comprises improved constructions of and
fittings for rain water, soil, and other pipes, where faucet and spigot joints are
used, made of cast or malleable iron, fire clay or other suitable material, and
specially applicable to the rain rhone thin iron pipes of buildings, all with the
object of enabling the individual pipes to be separately removed and inserted for
repair or being cleaned out, and thus dispense with the necessity of requiring to
remove all the pipes when any one of them gets choked or broken, as has been
necessary heretofore.
And in order that my said invention and the manner of performing or carrying
the same into effect or practice may be properly understood, I have hereunto
appended an explanatory sheet of drawings, in which the same reference letters
are used to indicate corresponding parts in all the figures where shown.
Figure is a perspective elevation of three rain or rhone pipes A A A² of
round section as fixed up against a building wall W. And Figure 2 is a corre-
sponding view showing one of the intermediate pipes or sections A as in the act
of being inserted or removed in accordance with my improvements by opening
the upper carrying shackle C of the faucet end A".
Figure 3 shows a sectional side elevation, and Figures 4 and 5 end views of
the faucet and spigot ends A", A, of one of the pipes A to a larger scale, as
formed with segmental projections a, a, at opposite angles on the inner and
outer surfaces respectively in accordance with my improvements as hereinafter
described.
Figure 6 is a front elevation of a square or rectangular form of rhone pipe A
and Figures 7 and 8 end views of the faucet and spigot ends A", A, as formed
with segmental projections a, a, on the back sides, and with sufficient clearance
in front to be able to remove these ends free of their projections a, a', and so
raise and remove any intermediate pipe, and preferably with a pinching screw «³
to hold the pipe in position when set. And Figures 9 and 10 show longitudinal
sections at right angles to each other of the square form of rhone pipe A shown
in Figure 6, as hung in its socket shackle B to the wall W.
Figure 11 shows a front and top edge view respectively of the socket shackle B
secured to the wall W by spikes or nails at for hanging the rhone pipes A by
a knee staple formed on the back of each faucet A".
Figure 12 is a top view of the faucet end A" of a pipe A. shown as fixed to
the wall W, by a square buckle form of shackle C. C', the plate part C being
secured to the wall W by a plate B and spikes or nails at b, and the strap
buckle part C secured to this by joint pins at C, or it might be by screw bolts
a pin a in front bar of shackle passing through a hole in faucet A". And
Figure 13 is a front view of the shackle part C C, corresponding to Figure 12.

page_text: Figures 14 to 20 are views of various arrangements of improved portable joints
on the ear, or annular bands or shackles C, C', for securing round the faucet
ends A" of these pipes to enable them to be removed or inserted in accordance
with these improvements.
Referring to these drawings, according to my invention the faucet end parts A"
of the pipes are made longer than usual, preferably about double the usual length,
and have cast or fitted on their inner surface, preferably near the centre of their
length, one, two, or more sectional or segmental projections or supporting
surfaces a, a, opposite to each other; and the extreme ends of the outer surfaces
of the spigot ends A are formed with corresponding segmental projections a', a¹,
to bear and rest on those a of the faucet ends A" when jointing or connecting
the pipes, and so that when any intermediate pipe of a set is desired to be
removed for cleaning out or repair, by simply turning it round by hand, these
segmental projections a, a', on the faucet and spigot ends pass one another at
the spaces between the segments, and the spigot end A falls to the bottom of
the elongated faucet end A", which clears its faucet from the pipe at the other
end and enables it to be at once lifted out, or vice versa, turned and raised
instead of lowered, and be replaced again by putting it in, in the same manner
and simply turning it round to bring the projections a' on the spigot end A"!!
to bear on those a on the faucet end A".
To enable these pipes to be portably secured to the wall of a building or
other place where they are to be used, and in their proper position over their
said segmental projections a, a', they are by a further improvement secured
round their faucet ends A" under the top bead Ax by special ear or annular
bands or ring shackles C, C', hinged, jointed, or so connected that one of these
can be easily removed or opened up when a length of pipe is to be lifted away
as shown in Figure 2. These bands would consist of circular, square, or other
forms of straps or rings C, C³, having the one half or part C secured to the
wall W of the building or other place where they are to be used by "batt"
joints, or by projecting lugs or flanges B and bolts or spikes driven into the
wall W at b. And the other annular half or segment of the band C¹ is
connected at its ends to the stationary flange part B either by having one a fixed
oscillating or hinged joint at C" and the other a portable or removable pin or other
equivalent joint at C2 as shown in front and edge views in their closed and open
positions in Figures 14 and 15, and suitable for the round pipes shown in
Figures 1 to 5 or both joints may be so jointed at C as to remove the outer
gripping segment when a pipe is to be lifted out as shown in Figure 12 for
square or rectangular forms of pipes. These joints would consist of overlapping
eyes or lugs, or projecting flanges on the ends C", C2, of the stationary and
portable parts C, C, of the bands secured together by removable pins or bolts,
or by folding shackles; or when flanged locking joints are used as shown at ce¹
in the three detail views Figure 16, one of these flanges would be formed
with a slotted hole to allow the head of the pin d to pass through, and be
given a quarter turn round to lock or unlock the T head part d and outer
shackle part C of the ring to the fixed part C; or otherwise as shown in the
five detail views Figure 17 in which the flanges c c overlap each other circum-
ferentially, one of the flanges say the inner flange c would be formed with a
round and slotted hole e" for the inner T end d of a locking pin d to turn round
and pass in or out through, and the pins be given a quarter turn round to lock
or unlock the T end part d' within its recess c¹ and so lock the two ends, c',
together. Or as shown in the detail views Figure 18 the one or tongue part c
would overlap or slide over or into a recess in the inside of the other e¹ and be.
formed with a square or rectangular slotted hole in the inner side of both
parts for the head of a square or rectangular pin d to work into, the turning
of which a quarter or so round by the head outside would secure both parts
together, and the one part c could be formed with a round recess on the inner
surface for the head d' of the pin d to so turn in. Or as shown in the detail views

page_text: Figure 19, the ends need only abutt together, leaving a slot el, across the
centre, and be formed with recessed checked segmental grooves e² and stops c³ on
the inner side and be secured together by a removable T or crosshead d on the
inner end of the securing pin d, the other ends of the crosshead taking down into
the sunk part of the segmental grooves ² and abutting against the stops in their
locked position, and turned by a round or other head d² outside. Or as shown in the
detail views Figure 20, the ends cel may be tongued and grooved or checked into
each other, and a recessed segmental annular groove d be formed in the inside of
the outer turning head d mounted on the end c of the shackle, which would work
into and against a projecting stop or stops d³ on the inside of one of the ends c¹ and
so lock these ends together, by a quarter turn, in one position of the head d², and
release it in the other. The cars CC on the lowest or ground pipe A² would
preferably be secured by screw bolts or screw pins, to prevent these being removed
except by the use of a screw key.
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
First. The construction or arrangement and combination of rain, water, and other
pipes formed with segmental projections at their faucet and spigot jointing ends,
and secured together by removable car or annular coupling bands, so that any
intermediate or individual pipe of a set can be removed or replaced without
disturbing the others, substantially as herein described, in reference to, and by way
of application shown in the accompanying drawings.
Second. The, construction and use of rain water and other pipes formed with
sectional or segmental projections or surfaces on their spigot and faucet jointing
ends, and having the latter of such length that any intermediate or individual pipe
of a set can be raised or lowered and removed or replaced without disturbing the
others, substantially as hercin described in reference to and by way of application
shown in the accompanying drawings.
Third. The securing of rain, water, and other pipes to a building wall or other
place by means of any of the special constructions of portable jointed or coupled car
or annular bands, so that these bands can be easily opened out when any intermediate
or individual pipe is to be lifted away or replaced, substantially as herein described
in reference to and illustrated in the accompanying drawings.
