Year: 1885

page_text: I, WILLIAM BRUCE, of 1, Sciennes Hill Place, Edinburgh, in the county of Mid-
Lothian, Clerk to the Works do hereby declare the nature of my invention for
IMPROVEMENTS IN DRAIN BENDS, AND BRANCHES WITH TRAPS COMBINED, to be
as follows:-
This invention has for its object improvements in the formation of Drain Bends,
Branches, with Traps combined, and self acting Drain flushing Basons. The bottom,
ends and sides of lower division, will be all formed in one piece, with faucet drain
joints formed on the inside of the Box. The upper parts will extend, and be
formed in divisions untill it reaches the necessary height at surface. The sides
and corners will be supported in buttress-shape, overlapping the sides.
The formation of Bends and Branches shall be right, and left-hand; and where a
Trap is combined in the same Box with a Bend, or Branch; the said trapped
connection also forming a Bend, and Branch connection. The said Trap and its
box connections will be slightly higher than the larger drain formation, of drain
pipe in the Box, into which the said Trap discharges. The whole formation of
said Trap shall be within the Box and on the inlet aide of the Trap; this said
connection will be ventilated by means of a pipe extending from the top of Trap,
to the surface, having a bell-shaped mouth piece below the surface grating; and
all placed inside the Box formation of man-hole.
No, Box Bend, or Branch shall have more than one faucet discharge-connection;
but shall have one, two, three, four, or more faucet inlet connections.
The Box for the flushing Bason shall be constructed as hereinbefore described,
for the Bend and Branch Boxes; but having one faucet discharge connection.
The side of Bason will be hinged to the sides of Box, and supplied with water by
means of a pipe, and stop-cock. And is so shaped, that it discharges the water
into the Box, and hence through the faucet connection of Box into the drain pipes.
The supports, and stop for bottom of Bason will be formed on a shelf above the
faucet discharge of Box. The Bason is so adjusted, that any given quantity of
water can be used for the flush.
The formation of pipes in Bend, and Branch Boxes, shall be the full depth of the
inlet, and outlet pipes; the bottom of these formations shall be made to the same

page_text: circle as the inside of the connecting pipes, and the sides above the centre shall be
formed nearly vertical, untill the height is nearly equal to the diar of the connecting
pipes, and the width of pipe formation will be slightly contracted at the top; but
leaving the formation of pipes in the bottom of Boxes always open for inspection,
or cleaning from the surface, when the covering plate of man-hole is removed.
When the Boxes are required for large drains; it is preferable to make the
upper divisions in slabs, having the joints joggled with cement, asphalte, or other
Buitable material, and retaining the formation of buttress's, as hereinbefore
described.
The spigot, and faucet connections of Boxes may be plain or as described in my
Provisional Specification, No 7579, dated 22nd June, 1885. Having a guide and
bead on spigot, with hole in faucet for pouring in asphalte or other suitable
material for forming a joint.
The Box Bends, Branches and Bason hereinbefore described, to be made of
glazed fireclay, or cast iron; and applicable to all size of drains, and street sewers.

Improvements in Drain Bends and Branches with Traps
Combined.
I, WILLIAM BRUCE, of 1, Sciennes Hill Place, Edinburgh, in the county of
Mid-Lothian, clerk to the works do hereby declare the nature of my invention
for IMPROVEMENTS IN DRAIN BENDS AND BRANCHES WITH TRAPS COMBINED, and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The objects of my Invention are improvements in the formation of Drain
Bends and Branch connections, which I form in a curved or circled line, when
constructing all Bends or Branch connections; and said connections are formed in
the bottom of Manhole Boxes, and open on the top for the purpose of inspecting
and ventilating the main drains, and connecting Branches.
According to this Invention, the Drain formation is formed in the bottom of
Manhole Box to a depth equal to the full diameter of the outlet pipe, below the
level, or sloped bottom of Box, thereby conducting the full flow of water or sewage
'passing in the pipes, and through the bottom of the Box, and thereby preventing
the common overflowing, such as takes place with the common semicircled
channel. The parts in bottom of Manhole Box, not occoupied with the drain or
pipe formation; are constructed and made with a declivity, or slope towards the
pipe formations.

page_text: In addition to the depth of pipe formation, already described, I form an upturn
on the aides and ends of the Manhole Boxes; said upturn being equal in height to
the top of the highest faucet of pipe formations in Manhole Box's, which still
further pervents all overflowing of sewage, or water from escaping out of the
Manhole Boxes to saturate the surrounding soil, or other material.
Under this Invention, I form strong deep faucets, for pipe connections in the
Manhole Boxes, for both the inlet and outlet pipes; for making the outlet con-
nection to tail drain; or the drain leading from the Manhole Box. I make a short
piece of pipe, with two spigot, or plain ends, one end of said pipe is placed into the
faucet of drain pipe, and the, other end is placed into the outlet connection, or
faucet of Manhole Box. Said outlet connection to drain can also be made by
means of a spigot formed on the outlet pipe connection or joint of Manhole Box.
In continuation of the Manhole Box, above the Bottom piece or section to the
required height at, or near the surface level, I make for the smallest Manhole's,
sides and ends, all made in one piece, having buttress shaped, or projecting corners;
said buttresses are constructed to overlap the sides and ends of the lower sections,
as shewn on the annexed sheet of drawings.
For the formation, or construction of the larger Manhole Boxes, I form the ends
and sides with slabs, and having overlapping buttresses at the corners and sides,
as shewn by the accompanying sheet of drawings, and said buttresses strengthens
the sides and ends, and by the overlapping arrangements, the buttresses pervents
the side and end slabs from moving inwards out of their proper position, and
adding strength to the retaining power of side and end slabs. In addition to the
buttresses formed on the corners and sides of said slabs, I joggle the vertical
joints, by means of two V, shaped groves cut out of each slab, or end joint of said
slabs, or at the end or side where a joint is to be formed, said V shaped grove, or
other hollow, suitable for the construction of a joggled joint, to be made opposite
each other, and each joint will be filled, jointed, or run up full with asphalte,
cement, pitch, or other suitable material, or mortar, during the building of each
course of slabs, during the erection of sides and ends of. said Manhole Boxes. The
level joints, or beds, of said slabs, and Manhole Boxes should be formed. with
cement, or other suitable mortar, or material.
In the outlet end of some Manhole Boxes, I, form a disconnecting trap with a
deep water seal, and having a cap on the tail, or outlet end which can be bedded
and pointed at the joints and made perfectly gas or air tight. When it is desirable
to inspect the outlet or tail drain, said cap, or cover can be removed for that
purpose, and after inspection it can be replaced to pérvent any smell from the tail,,
or outlet drain passing into the Manhole Box. Said Trap, with inspection cap is
formed in the Boxes, therefore access can be got to the tail drain from the inside
of Manhole Box. All the inlet drain formations in Manhole Box, between the
Trap, and inlet faucets of Branches are open on the top for inspection- and:
ventilation purposes. I, also form a disconnecting trap or any of the Branch inlet:
connections of Manhole Boxes, and said Trap will be ventilated, when required,
by means of a pipe, or tube, extending from the trap to the surface grating; said
pipe, or tube can be finished with a plain, or common pipe below. the surface
grating or with a bell-shaped mouth-piece to admit a sufficient quantity of air to
ventilate said Trap, and Branch drain, or connection, leading, or conducting water,
or sewage to said Trap,
When flushing the Drains, I form or construct a Tilting Bason, hinged to the
sides, or ends of a Manhole Box. The bottom piece of said Manhole Box will be.
rounded on one side, discharging the water towards the outlet faucet, or pipe
connection; said bottom piece will have one outlet faucet, or pipe connection, as
herein before described. Said Bason can be made of fireclay, or metal, also the
frame or division to which the hinges are attached, may be made of fireclay or
metal Said Tilting Bason can be filled by means of a water pipe with regulating
stop-cock, or valve, Waste water from Baths, or rain water may be discharged.
into the Tilting Bason; said Bason is so formed, and shaped, that it discharges a

page_text: certain quantity of water, when filled to the proper height and proportion, into the
bottom section, or division in height, of Manhole Box, and hence through the outlet
faucet of Box into the drains.
No claim is herein. made for the Tilting Bason and binges; I only claim the
construction of Manhole Box for flushing purposes, all as described, and shewn on
the accompanying sheet of drawings; that is, the construction of bottom section,
with water guides, and outlet connection, and the extension of ends ands sides, all
with buttress-shaped and overlapping corners, to or near the surface level, or any
other required height.
It is well known that selfacting Tilting Basons, made of various metals, and
supplied with regulating cocks, or valves, have been used many years ago for
flushing purposes in connection with sanitary arrangements.
In order that my Invention may be clearly and fully understood in every detail,
and carried into practical effect; made, constructed, built and used according to
the full meaning of my said Invention, as generally described hereinbefore; I have
annexed to this specification the accompanying sheet of drawings, and I now refer
to the figures and letters of reference marked thereon.

through the centre. A, A indicates the faucets, which are formed in each end of
the Box. B, is the pipe formation which in depth is equal to the full diameter of
the inlet, and outlet pipe; said pipe formation is rounded in the bottom, to the
same circle, or shape as the connecting drain pipes, untill the drain formation
reaches the centre of the pipe formation, leading to or from the Manhole Box, and
from the centre, of the connecting drain pipes, the pipe formation is formed nearly
vertical untill it reaches the bottom of Manhole Box, and thereby giving an
opening, for inspection, or other purposes, equal to the full diameter of the inlet
and outlet pipe, the whole distance between the faucets. C, C, is the bottom of
Manhole Box, at each side of the drain formation, said bottom has a slope, or
declivity towards the pipe formation, in centre of Manhole. The buttresses are
shewn at the corners of Box, at an angle of 45 degrees.

of Manhole Box, and shews the bead on the spigot end of pipes at the outer end of
faucet. E is the short piece of pipe for connection to the outlet faucet of
Manhole Box, and faucet of tail drain F. Said spigot ends and faucets here shewn,
indicates the pipe connections or joints as described in my specification No 7,579,
dated 22nd June, 1885. Having a guide and bead formed on the spigot end of pipe,
and a hole in the faucet for pouring in the jointing material.
Fig. 8, is a section of Fig. 1, on A-A, shewing the pipe formation and the two
faucets in the bottom piece of Manhole Box, and two upper divisions placed on the
top of the bottom, shewing the overlapping arrangements of corner buttresses,
said sectional divisions could be continued to any height, on the principal here shewn.
Fig. 9, is an elevation of Fig. 2 on B-B, shewing the end of one faucet, and
section of pipe, also the side of one faucet and drain formation as formed below
the bottom of Manhole Box. This figure 9 also shews the arrangement and con-
struction of the overlapping buttresses at the corners of Box, with two divisional
sections in height above the bottom piece, which can be reduced or added to in
numbers to suit the depth of any drain as herein before described..

bottom of Manhole Box, said Fig. also shew the form and outline of faucet above,
and below the bottom of Box, B, with its upturned sides, equal in height to the
top of faucet; this figure also shows two upper sections and the overlapping corner
buttresses.
Fig. 11, is a plan of a square Manhole Box, shewing a Bend passing through the
bottom, with pipe formation and bottom piece as herein before described, all made
in one piece. This plan shews the arrangement of building, and constructing the
ends and sides with four slabs: having double V, groved slabs at the joints for
forming a strong and secure joggled joint. The slabs are so arranged that each
course can be properly bonded over the course below, and retaining the over-
lapping buttresses, as herein before described.

side of Box, or main drain, and having a trapped connection in line with the main
drain; A, is the outlet faucet from Manhole to main drain, B6, is a continuation
of drain formation, in line with the main drain. C, is a righ-hand inlet Branch
at an angle of 60 degrees, or thereby, from the main drain. D6, is a righ-hand
Branch placed at right-angles from the main drain outlet. Branches C, and D6,
are curved and circled towards the outlet faucet, E6, represents the air or venti-
lating pipe off the front of trap, which can be carried upwards, to, or near the surface
level, and covered with a grating, or otherwise. As shewn on this plan, buttresses
are made on the side of this Manhole, in addition to those at the corners, and the
arrangement of slabs allows the proper bonding of each course in height, when more
than one course is required on the top of bottom piece, to bring the Manhole Box
to the required height, at or near the surface level.
Fig. 13, is a section of Fig. 12, on D-D, and the reference letters represent the
same parts as the letters on the former Fig. 12, that is, A is the outlet faucet of
Manhole B6, is the tail of trapped inlet Branch connection, and shewing the dis-
charge at tail of trap into the outlet pipe formation and faucet A. C, and De,
represents the inlet Branch connections as shewn by the former Fig. 12. E6, is
the air, or ventilating pipe, Fe, is the spigot end of inlet pipe to trap, G, is the
enlarged mouth-piece below grating at surface level. H, H, indicates the surface
line, or level; and the broken lines in the cover indicates a Manhole opening,
which will be fitted with an iron plate or plug. And when it is desirable to
ventilate the Manhole a perforated grating made of iron, or other suitable material,
is used instead of the iron plate or plug, already described; said perforated plate,
grating or cover used for ventilating the Manholes, is, preferably made slightly

page_text: raised, or rounded upwards on the centre, to pervent small stones, gravel, or other
surface material, in ordinary use, from filling up the perforations, Disconnecting
and ventilating Traps of this kind can be formed on any of the Branch connections
shewn by Figs. 4, 5, 6, 7, 12, 14, 15, 16, and 18.
Fig. 14, is plan of a Manhole Box with two inlets, one being in line with the
outlet faucet, or main drain connection, and the other inlet is a right-hand Branch
at right-angles from the main drain; said Branch connection being curved or
circled towards the outlet faucet connection. This plan shews the slabs with
joggled joints, in continuation of sides and ends, above the bottom piece, with
corner and side buttresses, all jointed, bonded and overlapped.
The broken lines at outlet pipe formation indicates the position of a Discon-
necting Trap, formed in the bottom of Manhole Box, between the inlet and outlet
connections. The circle A7, shews the inlet of Trap, receiving the water or sewage
from the two inlet connections, or Branches, and discharging into the Trap at, about
1", above the water level in Trap; B7 indicates a cap on the tail end of Trap,
covering and making perfectly gas, and air tight the tail end of Trap in Manhole
Box, between the water seal and outlet faucet of Manhole Box. This Discon-
necting Trap is formed in the bottom of outlet pipe formation all in one piece along
with the three faucets, bottom of Box with upturns equal in height to the top of
the highest faucet. In the case of large Manholes Boxes with large pipe formations
I do not limit myself to the production of pipe formations, Trap, and bottom to be
all made in one piece, And when constructing large sizes, I make the Manhole
Box bottoms with pipe formations and Traps in sections or pieces, all groved,
beaded, and bonded together.
A Manhole Box containing a Disconnecting Trap will have one, two three or
more inlet connections, as may be required; and in every case the inlet of Trap
and the drain formations between Trap and faucets of inlet Branch connections will
be open on the top for inspection and ventilating purposes. Disconnecting Traps
of this kind can be formed in Figs. 1, 2, 3, 4, 5, 6, 11, 12, 15, 16, 18, and 20, as
the position, or situation of any drains may require. All Manholes containing a
Disconnecting Trap should be finished with a large perforated plate or grating
at the surface line, inserted into a stone, iron, fireclay or other cover for the
purpose of supplying air and ventilation to the inlet Branch connections of
Manhole Boxes.
Fig. 15, is a plan of a Manhole Box with four inlet connections, three of these
are on the right-hand side of Manhole, or main drain formation. The construction
of the bottom piece with pipe formations, faucets and upturns, are the same as
hereinbefore described, and likewise the construction of ends and sides with slabs,
to suit the depth of any drain, with overlapping buttresses at the four corners, and
one at each side.
Fig. 16, is plan of a Manhole Box with the main drain outlet near the centre of
one end, and with one inlet at the opposite end, and two Branch inlets at each
side of Box. The construction of bottom piece and slabs forming the ends and
sides are of similar construction as herein before described.
Fig. 17, is an elevation on E-E, Fig. 16, shewing the pipe formation below the
under side of bottom piece and a cross section of the outlet pipe. This elevation
also shows the overlapping arrangement and construction of corner buttresses and
the jointing of slabs; this fig. also shews how the slabs are made in different
heights to suit the different depth of drains.
Fig. 18, is plan of a round Manhole Box, with two inlets and one outlet; said
inlets are formed at any angle, and in a round Box one, two, three or more inlets
may be formed as required for the number of drain Branches. The pipe formations
are made, and open on the top for inspection and other purposes, as hereinbefore
described at former figures.
Fig. 19, is an elevation of Fig. 18, on F-F, shewing a cross section of outlet
pipe, and end of faucet, also the pipe formations, with their faucets below the
bottom piece of Box, This elevation also shews the upper divisions with buttresses

page_text: overlapping the bottom piece, said divisions being circular, or round, all made in
one piece, said circular pieces are made suitable for the depth of any drain.
Fig. 20, is plan of a Manhole Box containing a bend and pipe formation passing.
through the bottom. The construction of bottom with pipe formations and faucets
are the same as hereinbefore described, with upturn in height equal to the top of
faucets, and all round the top of said bottom piece, I form a socket, or faucet to
prevent the next division in height from moving out of its proper position in
relation to the bottom piece. The continuation of this Manhole to the required height
at the surface level, is executed with round, or circular pipes, or tubes with spigot
and. faucet connections, said faucets are made plain, or with a guide-fillet formed
in the faucet to keep the next, or connecting spigot in its proper position all as
described at Fig. 24, GB.
No claim is herein made for the jointing of upper divisions, sections, or pipes
having plain or common spigot and faucet joints, without guide-fillet.
In bottom pieces with sockets or faucets formed round the top, are made Bends,
Branches, and connections at all required angles, said Manhole Box, bottoms having
one outlet, with one, two, three or more inlet connections.
Fig. 21, is plan of a Manhole Box with two inlets and one outlet; one of the
inlets being at the opposite end of Box from the outlet, with a left-hand Branch
connection at righ-angles from the main drain, and having a curved, or circular
discharge into the main drain formation. The pipe formations are made in one
piece, with three spigot ends which is placed into the double-faucets of inlet and
out pipe connections said double-faucets being made in seperate pieces checked and
fitted to receive the spigot ends of open pipe formations in the bottom of Manhole
Box. The three parts of bottom, not occoupied with pipe formations and faucets,
are groved on the under side to correspond, and fit on the bead, which is formed on
the top of 'pipe formation; with upturned edges or sides, equal in height to the
top of said faucets. The plan of this Manhole Box shews buttresses at each side in
addition to those at the corners.
Fig 22, is plan of a large Manhole Box, with four inlets and one outlet, and
constructed on the same principal as described under Fig. 21.
Fig. 23, is an elevation of Fig. 22, on H-H, shewing at the bottom, of said Fig.
a cross section of the outlet pipe, also a view, or inside diar of the inlet pipe at the
opposite side of Manhole. The end elevation of outlet faucet is shewn, with a flat
bed or bearing part on the under side; and the upper part is checked and fitted
for the bottom pieces of bottom, The broken line indicates the outline of faucet
as formed on the inside of Box. The inlet and outlet faucets are also made for
connections with built brick, or other sewers of any form or shape, and the faucets
are shaped to correspond with the cross section of any sewer or drain, also the
bottom part of the pipe formations are made the same shape or form, as the bottom
part of said inlet and outlet pipe, drain, and sewer connections.
This elevation shews the nature, or design of construction, when the sides and
ends are continued, or built upwards with slabs and overlapping buttresses, untill
the required height is obtained at, or near the surface level; when the Manhole is
covered with an iron, or other suitable cover, as the situation of the Manhole
permits. For easy access from the surface, or Manhole opening; deep Manholes
will have ladders formed in any of the four corners of Manhole, by inserting small
bars, or plates of iron, or other material; each end of said bars or plates will be
built, or bedded between the beds of side alabs, placed in a diagonal manner across
the corner of said Manhole's. No claim is herein made for the invention of said
ladders. When the slabs, with joggled joints, and overlapping buttresses are used
for the formation, or building of ends and sides of large and deep Manholes, and
not of sufficient retaining strength to resist the inward pressure of soil, earth, or
other surrounding material, it is recommended to use a backing of masonary, brick
or concrete at the outside of slabs, as retaining walls round the outside of alabs.
The mode of construction described for the Manholes; with glazed slabs, and
water tight beds and joints is applicable for the construction of sides and ends of

page_text: under ground water reservoirs, filters, tanks, cesspools for sewage and all similar
under ground, or water fittings in connection with sanitary arrangements. The
flow of said reservoirs, filters, tanks, and cesspools to be laid with checked, groved
and properly bonded, glazed slabs of fireclay, and along with the sides and ends,
may be surrounded with puddle, where required.
Fig. 24, is a section of Manhole bottom piece on F-F, Fig. 21, A³, is the inlet
pipe with plain spigot inserted into the faucet, and shewing the joint connection as
described in my specification N° 7,579, 1885. B8, shews the double-faucet with the
upper part cut away on the Manhole side, as indicated by the broken lines at H³, and
having a bead formed on the top which fits into a grove as shewn at D8, Fig. 25.
E8, is the Manhole side of outlet faucet and F8, is the outlet pipe inserted into a
faucet which has a guide formed in the shoulder of faucet to keep the pipe in a
proper position, when forming the joint G, with cement or other jointing material,
This mode of jointing is applicable to all drain pipes seperately, and by forming a
fillet or stopping all round the pipe at GB, with cement, lime, clay, or other mortar ;
hot liquid, or semiliquid asphalte, pitch or other suitable material can be poured
through the hole in top of faucet to fill up the grove all round the spigot end of
pipe, between said fillet, or stopping of mortar, and the guide-fillet which is made
in shoulder of faucet. The object of said guide-fillet is to keep the bore of one pipe
in an accurate position in relation to the bore of another pipe when forming the
joints.
Fig. 25, is a section on G-G, fig. 21, and the numbered reference letters refers
to the same parts as described at Fig. 24, and this section shews the outside
elevation of the left-hand Branch connection as shewn at Fig. 21.
Fig. 26, is a plan of a Manhole Box containing a tilting Bason for the purpose of
flushing drains; said Bason being hinged at each end to the Manhole Box.
Fig. 27, is a plan of the bottom of Manhole Box with one outlet faucet, and
water-guides from each end of Box to each side of said faucet.
Fig. 28, is a section of Manhole Box and tilting Bason on I-I, Fig. 26, and
on II, Fig. 27. The broken lines indicate the full tilt of Bason. The stops are
formed on the back and bottom of Bason; the stop on back rests against a T bar,
or stop extending from end to end of the Box with soft bearings, which forms the
stop, or rest for back of Bason when it is not in motion, or in the act of discharging
water;
said bar, or rest also forms a stop, against which, the fillet on bottom of
Bason strikes during the tilting or discharge of water into the bottom piece of said
Manhole. This Fig. shews the formation of faucet in bottom of Box, with the
opposite side rounded to facilitate the discharge of water towards the discharge
faucet. This section also shew the way, and principal of connecting the short piece
of pipe with two spigot ends to the faucet of tail drain and outlet faucet of
Manhole Box's.
Fig. 29, is an elevation on J-J Fig. 26, and J-J Fig. 27, shewing the bottom
of Box with corner buttresses, one upper division, or piece above the bottom section,
.with outside of hinge and tail drain connection.
The bottoms, and upper divisions, and slabs are all made of the best fireclay and
specially glazed; But I do not limit myself to construction in fireclay, glazed, or
otherwise finished; as Manhole Boxes, with pipe formations and traps, can be
made of cast iron, or other metal, or of concrete, cement, and other suitable
materials.
All sizes of outlet pipes are made to correspond with the size, or number of inlet
Branches, and said inlet Branches are formed, or made at any required angle from
the main drain, or outlet faucet.
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 :-
1. The formation of Drain, Bends, and Branches passing through the bottom of
Manhole Razes in donth naval to the full donth
diamaton of the inlet 1
