Definitions
- My invention relates to a novel system of sewerage or drainage of houses and towns or districts, and is based on the supposition that all sweepings, dust, kitchen waste, and various other debris more or less hard or solid will be collected and removed frequently by carts or other special appliances, and that rain-water or surface drainage will be separately conveyed away by its own system of pipes or conduits.
- the main object I have in view is to convey away these matters to such a distance from the town or district that they will no' longer be injurious, and to do this automatically and continuously before any fermentation is set up in closed vessels or conduits without contact with the air or with the surrounding earth.
- Figure l is a diagram illustrating the general arrangement of the system.
- Figs. 2 and 2 are sections at right angles to each other of the automatic discharge apparatus.
- Fig. 3 is asectionalview showing a check-valve.
- Fig. 4 is a vertical section of one of the collecting-vessels.
- Figs. 5 and 5 are respectively a sectional elevation and planillustrating the arrangement of apparatus at the central station.v Figs. 6, 6, and 6 illustrate automatic discharge apparatus similar in most respects to that shown in Figs. 2 and 2.
- Fig. 7 is a diagram illustrating the arteries of the district system terminating'in collecting-vessels. Figs.
- Fig. 12 is a vertical section showing the arrangement adopted when the conduit has to pass under an obstacle.
- Figs. 13, 14, and 15 are details illustrating the connection of a pressure-gage with the conduit, and Fig. 16 is avertical section showing two automatic collcctingwessels and their operating devices.
- the superficial area of'a large town is divided into several working districts, such as are indicated in the diagrammatic view, Fig. 1, the extent and boundaries of which are determined by the density of the population,
- N represents the general receivers for'the sewage, matters, located at the central station.
- -M M are exhaust-chambers at said station, in which a barometrical depression is maintained by suitable exhaust-pumps, (indicated by M).
- the sewage matters are drawn through a pipe, 2, from the receivers N, and carried off by the discharge-conduit 1?, while the gases are withdrawn from the receivers and pass off by dischargeconduit O.
- the apparatus at the central works shouldbe perfectly air-tight.
- chambers o-r reservoirs M is communicated throughout the system by means of the barometrical conduit B, leading to the collectingvessels m m in each district, 0 being the pipe or conduit which conveys the contentsof said vessels to the general receivers N, being connected therewith at the points 4.
- the districts are composed of branches or pipes of short length connected with the collecting-reservoir d and the collecting-vessels m m, as best shown in Fig. 7, the-extent ofthe district being limited only by the capacity of these vessels.
- the collecting-reservoir d discharges alternately into vessels at m through pipes 12, the valves of which are automatically opened and closed, as hereinafter described.
- the barometrical depression is communicated through conduit B, collecting-ves- IOO sels m m, and collecting-reservoir to the collecting-conduit A and its branches.
- the waste matters from a building are collected in an automatic discharge apparatus located just outside the building. During the process of filling this apparatus it is cut off from the collecting-conduit A by means of a valve.
- the automatic apparatus which is situated between the main soil or waste pipe D of the house and the collecting conduit or pipe placed under the roadway, is a light box of metal or other material, the shape and dimensions of which can be varied, as required. Its mechanism is such that it can be made so as to be placed in a very limited space, generally under the ground, as near as possible to the surface thereof, but ata suflicient depth to avoid the effects of frost. A simple hole in the yard or garden, into which the soil-pipe passes, is often sufficient to receive this apparatus. It is divided into two closed compartments by a vertical partition, a, the lower part only of which is pierced with holes or made of wire or lattice-work of any suitable metal.
- the soil-pipe D On one side of this partition in the upper part of the apparatus is the soil-pipe D from the house.
- a pipe, I) which passes through the body of the apparatus to allow of its junction with the pipe of the collectingconduit, situated farther on under the road- 1X1 the pipe I) a vertical sluice or valve, c,of thick glass, is fitted in the interior of the apparatus. Its seat is formed with a hole corresponding to the diameter of the soil-pipe.
- This sluice or valve composed of two polished plane surfaces sliding one upon the other, alternately intercepts and opens communication with the collecting-conduit.
- the face of the seat d of the valve is so arranged that the movable member, made of the same material and provided with caoutchouc, cannot leave it, whether open or closed.
- a metal float, g of suitable form, provided with a releasing device, 71,
- the mechanism is inclosed in a metal casing, j, formed with holes and having a metal cover or top, It, pro vided with a latch, a padlock, or any suitable fastening.
- the two compartments of the apparatus are also each covered with a plate, I, which can be easily opened to permit of cleaning either compartment. This cleaning will only be necessary at very long intervals.
- the releasing device h is a bent pin orfinger fixed to the float g. It is normally engaged and held by the forked end of a bell-crank lever, 6, pivoted at 7 to an arm orbracket, 8.
- the float t' is carried by the horizontal member of the lever 6, which normally rests on a stop, 9. (See Fig. 2".) ⁇ Vhen the level of the semi-fluid matter reaches float t, the latter rises, turning lever G on its pivot and withdrawing the forked end from engagement with pin h. Float 9, being thus released, rises with a sudden movement, opening valve 0. As the matter flows out pipe I), the float a.
- lever 6 first resume their normal position, and then as the liquid still farther subsides float g also falls until pin it strikes the lower end of lever 6, turning the latter slightly, and passes under and is caught by the forked end of said lever until once more disengaged by the filling ofthe vessel.
- the cover of the compartment into which the pipe D discharges is provided with a valve, W, capable of opening inward only, to facilitate the action of the atmospheric pressure within the apparatus when the valve 0 is opened, so as not to exhaust the siphons of the house'pipes.
- a light spring, 10, returns valve W to its seat when the valve 0 is closed.
- the apparatus, the partitions, the valve, and its seat may be made of any suitable metal or material. All the metal parts may be galvanized and coated with tar to insure preservation.
- the working of the apparatus is as follows:
- the apparatus receives the slops, fecal, and other fermentable matters from the soil or waste pipe of the house.
- the matters that are more or less dissolved in water pass through the first partition,a,all foreign bodies and paper not yet destroyed or insufliciently dissolved, and which the last siphon of the house has allowed to pass, being retained or quickly dissolved in the bottom of the apparatus without obstructing the vertical partition.
- the sirupy, muddy, and pasty liquids pass through the casing of the mechanism, and their level rising in the apparatus covers the first float, As soon as it is immersed in these matters, the float tends to rise, but is held by the releasing device h, which only acts when the level of the liquid rises to the small float 'i. At this momentthe first float, 9, being completly immersed, rises sharply and attains the final point of its travel in the apparatus,completely opening the valve 0 and the communication with the collecting conduit or pipe.
- the atmospheric pressure then acts through the valve ⁇ V upon the surface of the matters and drives them with force first through the partition, and afterward through the open pipe into this conduit,in which,as already stated,a low pressure'is constantly .maintained.
- the level immediately falls, compelling the small vfloat i and the releasing device h, with which it is provided, to resume their normal posi-' tion.
- the valve 0 still immersed in the liquid, automatically closes, and the releasing device upon which it then acts by its weight is set ready for the next action.
- the mechanism thus acts according as the height of the level of the liquid increases or diminishes.
- the valve 0 during its movement rubs continually against its seat d, and the to-and-fro movementwhich is imparted to it by the action of the float always keeps the mechanism in a perfect state of cleanliness.
- the valve can also be made of two plane surfaces united on one axis and both pierced with a hole at the same distance from this axis, or it may consist of three plane surfaces with a hole communicating with the conduit or pipe. The opening of the valve will then only be produced when the three holes by the play of the float are brought in front of each other. When one of the surfaces turns upon the common axis, so as to cover the hole of the other or of the two others, the proper closing of the valve is obtained.
- a check-valve, Fig. 3 is placed between the apparatus and the collecting-conduit. It allows not only .of completely shutting off the house when from any cause this becomes necessary, but it also automatically prevents in all cases the return of the matters from the conduit to the apparatus, and consequently to the house.
- the valve m is formed of a sphere or hemisphere of caoutchouc, which will rise under the action of a slight pressure of the matters or gases drawn by the atmospheric depression or partial vacuum in thecollectingconduit.
- the seat of the valve on the side indicated'by r slopes downward abruptly, and on the other side, 1, is brought to an edge, so that no solid matter. can lodge on it.
- the valve is guided by a rod, n, which moves in a smallbox, s. It is sufficient to screw up or down another rod, p, upon the first one to prevent the valve acting,and to thus'formja com-- plete obstruction.
- the collectingconduit A is placed in galleries, drains, or trenches under the roadway as near as possible to the houses, from which, by means of the automatic discharge apparatus, they receive the matters and liquids.
- the pipes which may he of wrought or cast iron, earthenware, I
- the conduit will consist of a number of pipes as long as it is possible to procure them. Its diameter will vary according to the number of houses it has to clear and the quantity of matter to collect.
- the numerous arteriesor branches of the collecting-conduit of a district should proceed in the shortest way toward the two collecting-vessels of this district after having received the matters from the adjacent smaller pipes, but
- Pipes of different diameter can thus be employed in the arteries of a district, (see q r s, Fig. 7,) as well as in the various branches of the same artery, (see't u 1 according to whether the quantity of materials they have to collect in their course is more or less great.
- Aspeeial piece, F of cast-iron
- an opening, G will be made in the pipes, in which will be screwed a small metal tube or pipe, H, Figs. 13, 14, and 15.
- This tube is constructed in such a manner that any person can test, by means, for example, of a gage, J, the barometrical depression which exists at thatpart of the conduit.
- This small pipe has a screwthreaded hole, I, closed at its upper part by a serew-plu g, K, of the same pitch and provided with a notch or nick, L.
- the pipe H has besides within it a drilled tube, M, which terminates at N in the hole I, which hole is hermetically closed by the screw K.
- the key-like termination L of the gage J is introduced into the notch or nick L of the screw K and is turned so as to cause the screw K to descend.
- the screwthread 0 of the gage which is the same as that of the screw K, engages with the pipe H, from which it follows that by turning the screw 0 the screw K will be screwed inward, and at the same time the gage will be completely screwed upon the pipe H.
- the neck Q made in the screwthread of the instrument will then communicate with the pipe M and with the gage, and the desired indication can be read upon the dial.
- the collecting reservoir receives at its upper part a pipe, 5, Fig. 7,-which conducts the gases of the collecting conduit directly into the the barometrical conduit B without passing through the automatic collecting-vessels.
- Thevessels (see Fig. 4,) which may be of metal, should be air-tight and placed underground at any point of the district as near as possible at the bottom of an incline and underneath the collecting-reservoir.
- each of the two vessels will be determined by the area of the district and thequantity of sewage matters to be received and forwarded in the twenty-four hours.
- Each vessel is composed of the following parts: an outershell or casing of metal, which need only be sufficiently strong to support with the sewage matters the atmospheric press-
- a check-valve m similar in form to the one before described, is placed at the upper part of the receiver. It allows of the outflow of sewage matters from the collectingconduit, but it prevents their return, as well as that of gases or of atmospheric pressure.
- a chamber, r of the same metal, in which ters77,ee1 s minates the barometrioal conduit B, which .never receives sewage matter and communicationwith' which is established on the one hand with the Works and on the other with the collecting-reservoir, (see Fig. 7,).and consequently with the collecti n g-conduit.
- Atmospheric pressure is exerted in the two vessels through the twoopenings s andt.
- the first opening, 25, is closed by a clack-valve, a, of metal, whichautomatically-opensinward when the atmospheric pressure acts upon it.
- the second opening, 8 is closed by a sliding valve, 12, of metal or other suitable material, attached through an opening arranged in the side of the chamber-to a rod, 00, which is provided at its upper part with a counter-weight, a".
- the barometrical conduit can likewise be closedin the interior of the chamber byva similar valve, 0, attached "directly to the same, metal rod. This rod in rising or falling under the action of the .float H actuates thetwo valves simultaneously. The valve o, how; ever, does not begin to open until the valve 0 is closed.
- the metal float H of any suitable shape, moves freely up or down the rod 00'.
- the automatic operation of the vessel takes place as follows: Let it be supposedthat the vessel is empty, the valve 0 open, and consequcntly the other valve, 1), closed andkept tight on its seat by atmospheric pressure.
- the barometrical depression caused by the pumps at the works is transmitted by means of the barometrical conduit and of the valve 0 to the interior of the vessel.
- the weight of the liquids contained in the collecting-reservoir 01' causes the valve m to rise, and the sewage matters are precipitated into the vessel with the gases which ⁇ have not been drawn through the upper part of the collecting-reservoir into the barometrical conduit B. Naturally these gases arethen immediately taken up by this conduit and'the sewage matters fall to the bottom of the receiver.
- Fig. 16 permit of obtaining between the two collecting-vessels of each district an automatic movement to insure the arrival of the sewage matters in one of them at the moment when the emptying of the other commences, and to arrange that the latter, being empty, cannot begin to fill before the first has become full, and vice versa.
- each float H operates valves within the chamber 14, which valves, being similar in construction and operation to those lettered c and c in Fig. 4, are not shown and need not be further described.
- the rods 00 pass through stuffing-boxes S and are connected to the bell-crank levers U, pivoted at T, and carrying counter-weights U U.
- To the levers U are pivoted connecting-rods X X", which have slots X at their farther ends, in which slides one end of a pin or bolt, Y.
- the valves 12 b correspond in construction and function to the valve m in Fig. 4-that is to say, they control the passage of matters from the collecting-reservoir to the vessels m on. through pipe 12.
- the rods a a are carried by opposite ends of the balance-beam G which is connected with the pin or bolt Y in slots X.
- Vessel m is supposed to be in process of emptying and vessel m in process of filling.
- the float H in thelatter rises sufificiently to operate the valves in casing 14, (first closing communication with the barometric conduit B and then opening communication with the atmosphere, as already described in connection with Fig 4,) it by the same movement tilts the lever U and counter-weight U, moves red X from left to right, and tilts beam 0 bringing the rod a. to bear on the topof rod-carrying valve 1), thus pressing the latter to its seat and cutting ofi' communication between the collecting-reservoir and vessel m.
- each of these conduits is composed of pipes of suitable material capable of resisting externally a pressure a little more than that of the atmosphere.
- Their diameters are calculated according to the cube of the sewage matters and gases to be carried off from the district at the time of day when the delivery will be the greatest. If these conduits communicate directly with the works, their diameter should be the same for the whole of their length. If, on the contrary, they are to distribute their contents or their gases into a similar conduit conveying the sewage of another district, the diameters should increase from the point of junction in proportion to the cube to be carried away.
- the works should be placed as near as possible to all the collecting-vessels of the differ ent districts of the town, and be joined to these vessels by the shortest road. They are provided with a series of reservoirs, M, in which pumps or pneumatic engines M of any suitable description, maintain in turn a strong barometrical depression. These reservoirs, being put alternately in communication with the barometrieal conduit B, transmit the de sired depression to the collecting-vessels and throughout the whole of the conduit, and they will produce in thegeneral receivers N the necessary depression, so that the atmospheric pressure acting upon the full collecting-vessels of the district will automaticallyforce forward their contents.
- the pumps or pneumatic engines M should be capable of taking up all the gases arising from the system as they are produced, and then forcing them through the gas-conduit O to the place selected for utilizing, treating, or destroying them without danger or trouble.
- gases can be made to undergo a change at the works, such as a cleaning orwashingin a series of vessels containing sulphuric acid. They can afterward be employed in the furnaces for heating the boilers, and in this way the conduit for the pumping forward of the gases may be dispensed with.
- the liquid-pumps or the suction and force engines may be of any suitable construction, and should also be capable of dealing with all the sewage matters as they arrive in the general receivers N, so as to force them afterward through the conduit P to the place chosen for their utilization, treatment, or purification.
- the sewage matters which come from the automatic collectingvessels through the conduit are received at 4 in the upper part of a series of general receivers placed one below the other, and it is from the lower part, 3, of
- Thecon'duits'for the pumping forward of the sewage matters and gases are constructed of any suit-able material. They should be able toresist the maximum internal pressure necessary for carrying the sewage matter and gases to their destination. Their diameters should be calculated by the quantity of sewage matters or gases to be pumped forward in the twenty-four hours.
- the apparatus arranged in the works forinsuring the regular working of the system throughout its whole extent should be completely and hermetically closed.
- the works can therefore be placed, if necessary,a'nd without inconvenience, in the midst of or in close proximity to a town or the center of a population, as in the case of water-works.

To all whom it may concern:
Be it known that I, ADRIEN LE MARQUAND, of Paris, France, have invented certain new and useful Improvements in the Sewerage or Drainage of Houses and Towns or Districts, and Apparatus Connected Therewith, (for which I have received patents in France, N 0. 170,07 9, dated April 19, 1887, and in England, No. 6,021, dated April 25, 1887,) of which the following is a specification.
My invention relates to a novel system of sewerage or drainage of houses and towns or districts, and is based on the supposition that all sweepings, dust, kitchen waste, and various other debris more or less hard or solid will be collected and removed frequently by carts or other special appliances, and that rain-water or surface drainage will be separately conveyed away by its own system of pipes or conduits. There thus only remain to be dealt with by my system of sewerage or drainage excreta, household slops, foul waters from factories, and other foul or polluted liquids and matters of a more or less pasty nature capable of becoming more or less dissolved in waterin short, all such matters as are generally discharged intothe waste or soil pipes of houses. The main object I have in view is to convey away these matters to such a distance from the town or district that they will no' longer be injurious, and to do this automatically and continuously before any fermentation is set up in closed vessels or conduits without contact with the air or with the surrounding earth.
In the accompanying drawings, which form part of this specification, Figure l isa diagram illustrating the general arrangement of the system. Figs. 2 and 2 are sections at right angles to each other of the automatic discharge apparatus. Fig. 3 is asectionalview showing a check-valve.

Figs. 8, 9, 10, and 11 are details illustrating the connection of different sections of the collecting-conduit.

Figs. 13, 14, and 15 are details illustrating the connection of a pressure-gage with the conduit, and Fig. 16 is avertical section showing two automatic collcctingwessels and their operating devices.
I will first give a general description of my system, and then explain the means and apparatus by which I carry it into effect.
The superficial area of'a large town is divided into several working districts, such as are indicated in the diagrammatic view, Fig. 1, the extent and boundaries of which are determined by the density of the population,
the quantity of water which is each day at the disposition of the inhabitants, the number of houses, and the character of the undulation of the land. v
In said Fig. 1, and also in Figs.'5 and 5, N represents the general receivers for'the sewage, matters, located at the central station.
-M M are exhaust-chambers at said station, in which a barometrical depression is maintained by suitable exhaust-pumps, (indicated by M The sewage matters are drawn through a pipe, 2, from the receivers N, and carried off by the discharge-conduit 1?, while the gases are withdrawn from the receivers and pass off by dischargeconduit O. The apparatus at the central works shouldbe perfectly air-tight.
The barometrical depression produced in.
chambers o-r reservoirs M is communicated throughout the system by means of the barometrical conduit B, leading to the collectingvessels m m in each district, 0 being the pipe or conduit which conveys the contentsof said vessels to the general receivers N, being connected therewith at the points 4.
The districts are composed of branches or pipes of short length connected with the collecting-reservoir d and the collecting-vessels m m, as best shown in Fig. 7, the-extent ofthe district being limited only by the capacity of these vessels. The collecting-reservoir d discharges alternately into vessels at m through pipes 12, the valves of which are automatically opened and closed, as hereinafter described. The barometrical depressionis communicated through conduit B, collecting-ves- IOO sels m m, and collecting-reservoir to the collecting-conduit A and its branches. The waste matters from a building are collected in an automatic discharge apparatus located just outside the building. During the process of filling this apparatus it is cut off from the collecting-conduit A by means of a valve. \Vhen the matter in such apparatus reaches a certain level, the valve is automatically opened, and the pressure of the atmosphere acting on its contents discharges the same violently into the collectingconduit A, by which the matters are conveyed to the collecting-reservoir d. From the latter the collected matters are discharged alternately into the vessels m m. The latter operate on the same principle as the automatic discharge apparatus-that is to say, when the matters in the vessel reach a certain level the valve of the barometrical conduit is automatically closed, the valve closing the part communicating with the atmosphere is opened, and the contents of the vessel are forced to the receivers N through conduit O.
This being the general principle and mode of operation of the system, I will now describe in detail the particular apparatus which it is preferred to employ in carrying the same into effect, beginning with the automatic discharge apparatus shown in Figs. 2, 2, and 6, 6, 6".
The automatic apparatus, which is situated between the main soil or waste pipe D of the house and the collecting conduit or pipe placed under the roadway, is a light box of metal or other material, the shape and dimensions of which can be varied, as required. Its mechanism is such that it can be made so as to be placed in a very limited space, generally under the ground, as near as possible to the surface thereof, but ata suflicient depth to avoid the effects of frost. A simple hole in the yard or garden, into which the soil-pipe passes, is often sufficient to receive this apparatus. It is divided into two closed compartments by a vertical partition, a, the lower part only of which is pierced with holes or made of wire or lattice-work of any suitable metal. On one side of this partition in the upper part of the apparatus is the soil-pipe D from the house. On the other side is a pipe, I), which passes through the body of the apparatus to allow of its junction with the pipe of the collectingconduit, situated farther on under the road- 1X1 the pipe I) a vertical sluice or valve, c,of thick glass, is fitted in the interior of the apparatus. Its seat is formed with a hole corresponding to the diameter of the soil-pipe. This sluice or valve, composed of two polished plane surfaces sliding one upon the other, alternately intercepts and opens communication with the collecting-conduit. The face of the seat d of the valve is so arranged that the movable member, made of the same material and provided with caoutchouc, cannot leave it, whether open or closed. To the arm of the lever e of this valve, which is mounted on the pin or axis f, is fitted a metal float, g, of suitable form, provided with a releasing device, 71,
actuated by another float, i, of smaller dimensions and placed above. The mechanism is inclosed in a metal casing, j, formed with holes and having a metal cover or top, It, pro vided with a latch, a padlock, or any suitable fastening. The two compartments of the apparatus are also each covered with a plate, I, which can be easily opened to permit of cleaning either compartment. This cleaning will only be necessary at very long intervals.
The releasing device h is a bent pin orfinger fixed to the float g. It is normally engaged and held by the forked end of a bell-crank lever, 6, pivoted at 7 to an arm orbracket, 8. The float t' is carried by the horizontal member of the lever 6, which normally rests on a stop, 9. (See Fig. 2".) \Vhen the level of the semi-fluid matter reaches float t, the latter rises, turning lever G on its pivot and withdrawing the forked end from engagement with pin h. Float 9, being thus released, rises with a sudden movement, opening valve 0. As the matter flows out pipe I), the float a. and lever 6 first resume their normal position, and then as the liquid still farther subsides float g also falls until pin it strikes the lower end of lever 6, turning the latter slightly, and passes under and is caught by the forked end of said lever until once more disengaged by the filling ofthe vessel.
The cover of the compartment into which the pipe D discharges is provided with a valve, W, capable of opening inward only, to facilitate the action of the atmospheric pressure within the apparatus when the valve 0 is opened, so as not to exhaust the siphons of the house'pipes. A light spring, 10, returns valve W to its seat when the valve 0 is closed.
The apparatus, the partitions, the valve, and its seat may be made of any suitable metal or material. All the metal parts may be galvanized and coated with tar to insure preservation.
The working of the apparatus is as follows: The apparatus receives the slops, fecal, and other fermentable matters from the soil or waste pipe of the house. The matters that are more or less dissolved in water pass through the first partition,a,all foreign bodies and paper not yet destroyed or insufliciently dissolved, and which the last siphon of the house has allowed to pass, being retained or quickly dissolved in the bottom of the apparatus without obstructing the vertical partition. The sirupy, muddy, and pasty liquids pass through the casing of the mechanism, and their level rising in the apparatus covers the first float, As soon as it is immersed in these matters, the float tends to rise, but is held by the releasing device h, which only acts when the level of the liquid rises to the small float 'i. At this momentthe first float, 9, being completly immersed, rises sharply and attains the final point of its travel in the apparatus,completely opening the valve 0 and the communication with the collecting conduit or pipe.
The atmospheric pressure then acts through the valve \V upon the surface of the matters and drives them with force first through the partition, and afterward through the open pipe into this conduit,in which,as already stated,a low pressure'is constantly .maintained. The level immediately falls, compelling the small vfloat i and the releasing device h, with which it is provided, to resume their normal posi-' tion. While the level in falling allows the float g to descend, the valve 0, still immersed in the liquid, automatically closes, and the releasing device upon which it then acts by its weight is set ready for the next action. The mechanism thus acts according as the height of the level of the liquid increases or diminishes. The valve 0 during its movement rubs continually against its seat d, and the to-and-fro movementwhich is imparted to it by the action of the float always keeps the mechanism in a perfect state of cleanliness.
The valve can also be made of two plane surfaces united on one axis and both pierced with a hole at the same distance from this axis, or it may consist of three plane surfaces with a hole communicating with the conduit or pipe. The opening of the valve will then only be produced when the three holes by the play of the float are brought in front of each other. When one of the surfaces turns upon the common axis, so as to cover the hole of the other or of the two others, the proper closing of the valve is obtained. It will be understood that when this valve is shut the pressure of the liquid upon its surface and the atmospheric pressure which acts upon it by reason of the barometrical depression maintained in the collecting conduit or pipe will keep it tight upon its seat, and that the polished sur facesof glass, for examplewill not oxidize or deteriorate, although immersed in the liquid, and that placed thus one against the other, they insure a complete and tight closing of the apparatus.
A check-valve, Fig. 3, is placed between the apparatus and the collecting-conduit. It allows not only .of completely shutting off the house when from any cause this becomes necessary, but it also automatically prevents in all cases the return of the matters from the conduit to the apparatus, and consequently to the house. The valve m is formed of a sphere or hemisphere of caoutchouc, which will rise under the action of a slight pressure of the matters or gases drawn by the atmospheric depression or partial vacuum in thecollectingconduit. The seat of the valve on the side indicated'by r slopes downward abruptly, and on the other side, 1, is brought to an edge, so that no solid matter. can lodge on it. The valve is guided by a rod, n, which moves in a smallbox, s. It is sufficient to screw up or down another rod, p, upon the first one to prevent the valve acting,and to thus'formja com-- plete obstruction.
e If the quantity of water which is in the house is not sufficient to allow of the evacuation through a general pipe uniting the product of all the waste-pipes, or if the general evacuatingpipe cannot be constructed for some reason, the matters are caused to fall directly from the fall-pipe D into the automatic I that the closing of the valve 0 shall never allow the liquids to fall below the prolonged pipeD. i
Collecting conduit or pipe.-The collectingconduit A is placed in galleries, drains, or trenches under the roadway as near as possible to the houses, from which, by means of the automatic discharge apparatus, they receive the matters and liquids. The pipes, which may he of wrought or cast iron, earthenware, I
or other suitable material, need only be capable of supporting externally a pressure a little higher than that of the atmosphere; but
the joints must be strictly tight. The conduit will consist of a number of pipes as long as it is possible to procure them. Its diameter will vary according to the number of houses it has to clear and the quantity of matter to collect. The numerous arteriesor branches of the collecting-conduit of a district should proceed in the shortest way toward the two collecting-vessels of this district after having received the matters from the adjacent smaller pipes, but
as much as possible without communicating" with each other on the way. .(See Fig.7.) Pipes of different diameter can thus be employed in the arteries of a district, (see q r s, Fig. 7,) as well as in the various branches of the same artery, (see't u 1 according to whether the quantity of materials they have to collect in their course is more or less great.
ing of the system, it .will be necessary to conform as much as possible to thefollowi ng. rules:
First. When it is desired to etieet thejunction of a pipe conveying simultaneously the barometrical depression and the sewage matters with another pipe intended for the same purposes, the junction of the one which will deliver its matters to the other will be made upon the upper part of the other by means of aspecial piece (see Figs. 8, 9, 10) of variable form, with single or double branches, and of increased diameter at the point ofjunction.
Second. \Vhile placing ordinarily the collecting-conduit in the direction of the slope or incline of the district, it will be arranged at different parts in lengths of variable but slight inclination, discharging one into another. (See Fig. 11.) It will be understood that a pipe following a rapid decline will always be full at that part which is the lowest, even with a small quantity of matter in it,and that it will be useless to attach to this part any pipe from a house. Vith the arrangement indicated, while thus facilitating the equal distribution of the liquids and of the gases in the conduit, the barometrical depression therein is also equalized as much as possible. Theadvantage to be derived from rapid declines for carrying forward the matters is no doubt lost; but this apparent loss is more than compensated for by the acceleration in the speed of the matters produced by their being carried forward by the gases,whose passage is thus favored and whose speed is much greater. Moreover, this arrangement facilitates the continual formation in the conduit of lumps of matter, which, being thrown sharply forward in a series of jerks, constantly brush or rub the sides of the pipes, thus insuring their cleanliness and rendering obstruction or stoppage more difficult.
Third. The siphon-passages-that is to say, the parts which have to pass under an obstacleare provided with a special apparatus, which is represented in Fig. 12,and is arranged as follows: Aspeeial piece, F, of cast-iron, is placed on each side, right and left, of the conduit at the places where the bend for the passage of the siphon begins and ends. These pieces are connected at w x to two bent pipes, y and 2 of varying diameters, and which are placed under the obstacle to be avoided. Through the lower pipe, 2 the sewage matters will pass, while the gases will flow exclusively through the upper one, 3 as soon as the siphon is full. The sewage matters from the conduit, and which fall into a, will drive into ba volume equal to their own weight. The gases, following the easiest route, will be drawn in at c, and will re-enter the conduit at d on their way to the collecting-vessels. ing the cover 6 an opening will be made for examining, cleaning, or repairing the apparatus. In the event of the conduit becoming completely full, and to prevent any matters by a rod, '5, upon which it rests when not in' action. As soon as the level of the sewage matters reaches the float, it will rise and close the pipe 1 by means of the sphere or hemisphere of indie-rubber with which it is provided at its upper part. As soon as the level of the liquid falls-that is to say, when the collecting-conduit most requires the siphon to workthe float falls to its position of rest. In some cases it will be sufficient to make the two ends of a siphon communicate by a small pipe placed in the siphon itself or parallel to it to establish equilibrium in the depression.
Fourth. At intervals in the conduit,as well By rais as in the greater part of the apparatus, an opening, G, will be made in the pipes, in which will be screwed a small metal tube or pipe, H, Figs. 13, 14, and 15. This tube is constructed in such a manner that any person can test, by means, for example, of a gage, J, the barometrical depression which exists at thatpart of the conduit. This small pipe has a screwthreaded hole, I, closed at its upper part by a serew-plu g, K, of the same pitch and provided with a notch or nick, L. The pipe H has besides within it a drilled tube, M, which terminates at N in the hole I, which hole is hermetically closed by the screw K. When it is wished to ascertain the barometrical depression at any desired point where one of these pipes H is situated, the key-like termination L of the gage J is introduced into the notch or nick L of the screw K and is turned so as to cause the screw K to descend. The screwthread 0 of the gage, which is the same as that of the screw K, engages with the pipe H, from which it follows that by turning the screw 0 the screw K will be screwed inward, and at the same time the gage will be completely screwed upon the pipe H. The neck Q made in the screwthread of the instrument will then communicate with the pipe M and with the gage, and the desired indication can be read upon the dial. It will be seen that even should the gage not be withdrawn there can be no escape and no loss. If, on the contrary, the gage has to be immediately withdrawn, it is only necessary to unscrew it. The screw K, following all the movements of the key L, will rise, first closing the pipe M and reaching the top of the opening G with the end of the screw-thread of the gage, which can be withdrawn. The screw K is thus antomatically putin place again and the closing is hermetic.
Fifth. Finally, to guard against all uncertainties, it will be prudent to unite all the branches at their meeting-points at the intersections of the drains and to provide them with cocks, valves, or sluices to permit of the sewage matters taking difierent directions, according to circumstances. When thecondnit passes under a road having houses on each side, it will be understood that a pipe should be laid on each side and naturally of a. diameter smaller than if a single pipe had to receive the sewage matters from all the houses in the road. If the roadway is narrow, the conduit will branch off from each house to the two pipes, so that by means of cocks or valves the sewage matters from the houses may be let into either of these pipes. If the roadway is broad and this arrangement would necessitate too much work, communication between these two pipes should be made only at intervals, or, if the road is not long, at its two ends only. With a conduit thus constructed and exclusively in communication with the discharge apparatus before described, which under the influence of the atmospheric pressure.
ure will force through it the sewage matters put into motion by the barometrical depress- 1on, and with the rapid passage of the gases above thesewage matters, obstructions and stoppages in-the pipes will be impossibleand the system will work without interruption.-
Automatic collecting-vessels, (Fig.4.)The arteries of each district terminate separately and directly in a collecting-reservoir, d", (see Fig. 7,).which, placed above the two automatic collecting-vessels m m, distributes the sewagematters of the conduit alternately'into each of them in a single stream. The capacity of the collecting-reservoir should be calculated to receive the contents of the conduits of the district during the time necessary for the" automatic emptying of each of the two collecting-vessels. In this manner the emptying of the sewage matters of the conduits even in the event of one of the vessels being out of action on account of damage or other cause can be assured. Communication between the bottom of this collecting-reservoir and the automatic collecting vessels is established by a pipe 12, Figs. 4, 7, and 16, adjoining the check-valves. The collecting reservoir receives at its upper part a pipe, 5, Fig. 7,-which conducts the gases of the collecting conduit directly into the the barometrical conduit B without passing through the automatic collecting-vessels. Thevessels, (see Fig. 4,) which may be of metal, should be air-tight and placed underground at any point of the district as near as possible at the bottom of an incline and underneath the collecting-reservoir. The
dimensions of each of the two vessels will be determined by the area of the district and thequantity of sewage matters to be received and forwarded in the twenty-four hours.
Each vessel is composed of the following parts: an outershell or casing of metal, which need only be sufficiently strong to support with the sewage matters the atmospheric press- A check-valve, m similar in form to the one before described, is placed at the upper part of the receiver. It allows of the outflow of sewage matters from the collectingconduit, but it prevents their return, as well as that of gases or of atmospheric pressure. A
rod, 8 passes through a stuffing-box and bears upon the rod 13'of the valve, in order to stop its action during the filling of the vessel. As the vessels automatically fill and empty, so are the two valves of their two inlets controlled by a movement which will be hereinafter described. Another check-valve, J, is placed at the lower part of the vessel. It serves exclusively to establish communication between the sewage matters of the vessel and thespecial sewage-conduit 0, leading directly to the central works. Its arrangement permits of its allowing these matters to pass, but under all circumstances to prevent their return. Above the vessel, and forming a part of it, is placed a chamber, r, of the same metal, in which ters77,ee1 s minates the barometrioal conduit B, which .never receives sewage matter and communicationwith' which is established on the one hand with the Works and on the other with the collecting-reservoir, (see Fig. 7,).and consequently with the collecti n g-conduit. Atmospheric pressure is exerted in the two vessels through the twoopenings s andt. The first opening, 25, is closed by a clack-valve, a, of metal, whichautomatically-opensinward when the atmospheric pressure acts upon it. The second opening, 8 is closed by a sliding valve, 12, of metal or other suitable material, attached through an opening arranged in the side of the chamber-to a rod, 00, which is provided at its upper part with a counter-weight, a". The barometrical conduit can likewise be closedin the interior of the chamber byva similar valve, 0, attached "directly to the same, metal rod. This rod in rising or falling under the action of the .float H actuates thetwo valves simultaneously. The valve o, how; ever, does not begin to open until the valve 0 is closed. The metal float H, of any suitable shape, moves freely up or down the rod 00'.
The automatic operation of the vessel takes place as follows: Let it be supposedthat the vessel is empty, the valve 0 open, and consequcntly the other valve, 1), closed andkept tight on its seat by atmospheric pressure. The barometrical depression caused by the pumps at the works is transmitted by means of the barometrical conduit and of the valve 0 to the interior of the vessel. The weight of the liquids contained in the collecting-reservoir 01' causes the valve m to rise, and the sewage matters are precipitated into the vessel with the gases which {have not been drawn through the upper part of the collecting-reservoir into the barometrical conduit B. Naturally these gases arethen immediately taken up by this conduit and'the sewage matters fall to the bottom of the receiver. The level of liquid in rising carries with it the float H, which slides along rod to. When it encounters the tappet I, with which the rod is provided at its upper part, it lifts it, carrying with it the two valves o and 05. At this moment the vessel is full of sewage matters, the valve 0 is closed, the other valve, 1), has just opened,
and the atmospheric pressure, passing in at V, has replaced in the interior the barometrical depression which previously existed there.
The atmospheric pressure then acts upon the valve 0'. The sewage matters no longer pass through the valve in and are drawn in by the corresponding valve of the other vessel. The suction or draft produced at the works in the general receivers of the sewage matters causes the valve J to rise, and the atmospheric pressure acting in the vessel in upon the liquids which it has just received forces them forward ICO IIO
violently and automatically into the special liquid-conduit G. The float H, having'then fallen with the level of the liquid, meets the tappet K, fixed to the lower part of the rod carries it with it, and before the level can fall below the valve J the valve 22' shuts at the same time that the sluice-valve e, on the contrary, opens. The depression of the barometrical conduit is reestablished in the vessel, and as soon as the second vessel is full the valve it? again rises, the sewage matters again enter the receiver, and the same operation takes place, being in like manner repeated alternately and indefinitely in the two vessels.
The arrangements shown in Fig. 16 permit of obtaining between the two collecting-vessels of each district an automatic movement to insure the arrival of the sewage matters in one of them at the moment when the emptying of the other commences, and to arrange that the latter, being empty, cannot begin to fill before the first has become full, and vice versa.
The rod a7 of each float H operates valves within the chamber 14, which valves, being similar in construction and operation to those lettered c and c in Fig. 4, are not shown and need not be further described. The rods 00 pass through stuffing-boxes S and are connected to the bell-crank levers U, pivoted at T, and carrying counter-weights U U. To the levers U are pivoted connecting-rods X X", which have slots X at their farther ends, in which slides one end of a pin or bolt, Y. The valves 12 b correspond in construction and function to the valve m in Fig. 4-that is to say, they control the passage of matters from the collecting-reservoir to the vessels m on. through pipe 12. The rods a a are carried by opposite ends of the balance-beam G which is connected with the pin or bolt Y in slots X.
The operation is as follows: Vessel m is supposed to be in process of emptying and vessel m in process of filling. \Vhen the float H in thelatter rises sufificiently to operate the valves in casing 14, (first closing communication with the barometric conduit B and then opening communication with the atmosphere, as already described in connection with Fig 4,) it by the same movement tilts the lever U and counter-weight U, moves red X from left to right, and tilts beam 0 bringing the rod a. to bear on the topof rod-carrying valve 1), thus pressing the latter to its seat and cutting ofi' communication between the collecting-reservoir and vessel m. By the same movement of beam G the valve b" is released and is free to rise and admit the passage of matter from the reservoir to the vessel m. When the latter is empty, the descent of rod :0 has moved rod X from left to right; but its slot simply moves along the pin Y, without affecting the position of beam 0'. It is not until vessel 12?.
fills that the beam is again tilted to the left, freeing valve b and engaging valve b This operation with the necessary intervals will be repeated indefinitely.
Central pumping works, (Figs. and 5.)The
barometrical conduit B and the sewage-conduit 0 put the automatic collecting-vessels m m in direct connection with the central works. Each of these conduits is composed of pipes of suitable material capable of resisting externally a pressure a little more than that of the atmosphere. Their diameters are calculated according to the cube of the sewage matters and gases to be carried off from the district at the time of day when the delivery will be the greatest. If these conduits communicate directly with the works, their diameter should be the same for the whole of their length. If, on the contrary, they are to distribute their contents or their gases into a similar conduit conveying the sewage of another district, the diameters should increase from the point of junction in proportion to the cube to be carried away.
The works should be placed as near as possible to all the collecting-vessels of the differ ent districts of the town, and be joined to these vessels by the shortest road. They are provided with a series of reservoirs, M, in which pumps or pneumatic engines M of any suitable description, maintain in turn a strong barometrical depression. These reservoirs, being put alternately in communication with the barometrieal conduit B, transmit the de sired depression to the collecting-vessels and throughout the whole of the conduit, and they will produce in thegeneral receivers N the necessary depression, so that the atmospheric pressure acting upon the full collecting-vessels of the district will automaticallyforce forward their contents.
The pumps or pneumatic engines M should be capable of taking up all the gases arising from the system as they are produced, and then forcing them through the gas-conduit O to the place selected for utilizing, treating, or destroying them without danger or trouble. These gases can be made to undergo a change at the works, such as a cleaning orwashingin a series of vessels containing sulphuric acid. They can afterward be employed in the furnaces for heating the boilers, and in this way the conduit for the pumping forward of the gases may be dispensed with.
The liquid-pumps or the suction and force engines may be of any suitable construction, and should also be capable of dealing with all the sewage matters as they arrive in the general receivers N, so as to force them afterward through the conduit P to the place chosen for their utilization, treatment, or purification.
The sewage matters which come from the automatic collectingvessels through the conduit are received at 4 in the upper part of a series of general receivers placed one below the other, and it is from the lower part, 3, of
IIO
these receivers, in the interior of which theatmospheric pressure is caused to act, that the pumps draw the sewage matters to pump them forward.
r r" F driven by any suitable motor.
' 377,681 V V w Thecon'duits'for the pumping forward of the sewage matters and gases are constructed of any suit-able material. They should be able toresist the maximum internal pressure necessary for carrying the sewage matter and gases to their destination. Their diameters should be calculated by the quantity of sewage matters or gases to be pumped forward in the twenty-four hours. g
The pumps and machinery of the works are For cases of urgency, all the parts of the works are provided with additional or supplementary parts.
The apparatus arranged in the works forinsuring the regular working of the system throughout its whole extent should be completely and hermetically closed. The works can therefore be placed, if necessary,a'nd without inconvenience, in the midst of or in close proximity to a town or the center of a population, as in the case of water-works.
In some large towns it will be advantageous to replace the barometrical conduit by pumps effecting directly the barometrical depression in the collecting-conduit through the collecting-reservoirand in the collecting-vessels of each district; but it will then be necessary not to pump the gases forward through a special conduit, but to destroy themor utilize them on the spot, In very large towns there should be several works connected together, so as to distribute the power required, and in. the smaller towns, where there would only be one district, the two collecting-vessels of this district shouldbe placed in the works.
