To a/Z whom t may concern.'

' Be it known that I, WILLIAM J. HOUGH, citizen of the United States, residingr at Albany, in the county of Albany and State of New York, have invented new and useful Improvements in Catch-Basins for Sewers, of which the following is a specification.

My invention relates to catch-basins for sewers; and it consists in the novel devices and novel combinations of parts and devices herein shownanddescribed, and more particularly pointed out in the claims.

The objects of my invention are to provide with a catch-basin which is interposed be.-y

twee-n the streetsurface and a sewer means and devices by which a separation of the larger pieces of bothfloatable and sinkable substances washed toward the catch-basin by the street surface water may be separated from'the smaller pieces of those substances and the smaller pieces and particles of iioatable and sinkable substances be readily separated from each other and the latter be in part run into the sewer to be ioated off through the sewer to a discharge therefrom, while the former may be deposited into suitable removable sedimentary vessels and the sewer-gases be prevented from escaping from the sewer by the way of the catch-basin to the street, as heretofore.

Other objects and advantages of the inven tion will be yfully understood from the follow-v ing description and claims when taken in connection with the annexed drawings, 'in three sheets, in which- Figure l isa View in plan of my improved catch-basin at its street-intake. Fig. 2 is a longitudinal section of the same at line 1 in Fig. l. Fig. 3 is a transverse section atline 2 in Fig. 1.( Fig.` 4 is a horizontal section at line 3 in Fig. 2. Fig. 5 is a horizontal section at line 4 in Fig. 2. Fig. 6 is a horizontal section at line 5 in Fig. 2. Fig. 7 is a plan view of preferred'form of device for supporting the sedimentary vessels. Fig. S is a view, part in section, of the coupling device between standards and seating-bars of said supporting device and also the upper end of a standard. Fig. 9 is a view of the upper side of the said coupling device. Fig. lO is a section, on enlarged scale, showing preferred forms of construction of certain parts; and-Fig. l1

is a. section, on enlarged scale, of thevalveseat and wall of an intake-section of the trap, Abetween the chamber of the basinand its discharge-opening.

Similar letters of reference referto similar parts throughout the several'vie'ws.l

In the drawings,A is the catch-basin, which may be made of any suitable materialfand of size and proportion adapted to give'it the capacity for receiving the several devices to be assembled and combined within its chamber foroperations, as hereinafter described. My preferred form of construction shown in the drawings Vconsists of a metal vessel formed of sheet-metal walls A', made slightly concavoconvex in a horizontal direction and on straightlines in a vertical direction and provided `with coupling-anges a a, preferably integral with the plates of said wallsand secured together by suitable rivets ct. This vessel is made with a vertical length of from six to eight feet. The several walls of this catch-basin and their adj unctsl are coated with a suitable material adapted to prevent air and water havingV contact withthe surfaces of the metal of said basin, so that oxidation of the same may be prevented. This catch-basin may be backed all around with sand or brick, yet in some cases, as when the metal of walls A' is thin, I prefer to reinforce said walls by walls B of concrete, formed of Portland or natural*hydrauliccement combined with sand and broken stone orgravel, mixed and applied and rammed in accordance with the best methods of concrete construction, and in vthis concrete may be embedded suitable cast-ironpieces (not shown) set on' the top of the concrete walls to prevent wear lby attrition or be set elsewhere for strengthening the walls against pressure by frost. These concrete walls B are tapering and may be stepped as they run upward as may be preferred, so that frost may be prevented from heaving the same. The bottomof the basin is preferably formed of similar hydraulic cement.

C is the discharge-opening from the chamber of the catch-basin', which opening communicates to the sewer (not shown) through the medium of the conduit C', leading from the said basin to said sewer.

D is the intake-opening, which communi- IOO cates from the street-gutter S to the chamber of the basin A. This intake-opening D is of grate form and consists of parallel bars b b and openings c c alternating, the bars being of metal and of sufficient size to give them strength to resist strains which may tend to break or bend them, while the openings c c are narrow-say about three-eighths of an inch Wide-so as to adapt this intake to separate the larger pieces of both oatable and snkable substances from the smaller pieces of the same substances, respectively, by the former being carried past this grate-form intake by riding on said parallel bars b b, and the latter being carried through the slot-form openings c c by the water from the street-gutter G into the said basin. The parallel bars b and slot-form openings c are made to run in direction parallel with the line of direction of the flow of the water in street-gutter G, in which this intake-opening D is placed, and not transverse to said direction of Iiow of the said water. By this parallel arrangement of the said bars and the alternating slot-form openings of the intake-openingD in relation to the line of direction of the flow of the streetwater in gutter G, as indicated by arrow 1 in Fig. l, both the floatable and sinkable substances of larger size than the width of the openings c e-such as pieces of wood, large leaves, and pieces of brick, stone, cans, &c.- may freely pass forward over the bars ZJ b and be clearly discharged from off the same at their terminals b', which terminals have their upper sides relatively above the plane of the upper side of the frame members b2 b2 of the said grate-form intake-opening D, as shown in Figs. l and 3, while the smaller pieces or parts of said oatable and sinkable substances will readily pass down through the slot-form openings c c into the receptacle below with the water taken in by the said intake-opening. It should be understood that the aggregated areas of the slot-form openings c c of this intake-opening D should be but a little larger than the area of the discharge-opening C, leading from the chamber of the catchbasin to the conduit C, communicating to t-he sewer, which is not shown. As it is evident that an intake-opening of any form employed and much greater than the dischargeopening C may take in such a volume of water as to quickly fill the chamber of the catchbasin to overliowing, in which case other devices and parts of this invention would be rendered more or less ineectual for obtaining all the benecial results designed to be secured. This intake-opening D is removable at will from its frame or setting E, which latter is also removable at will from the fixed supporting-frame F, which latter is shown to have its support on the upper end of the walls of the catch-basin in its reinforcing concrete outer'walls B, Figs. 2 and 3.

The removable frame E, serving as a setting-frame for the removable intake grateform opening D, maybe of any suitable form of construction adapted to support Ithe said intake-opening at a suitable distance above the plane of the upper end of the catch-basin, as shown in Figs. 2 and 3, and give it strength and stiffness for supporting wheels of vehicles, animals, the., without liability of breaking down.

G G are removable sedimentary vessels suitably arranged and supported beneath the intake-opening D and within the upper portion of the chamber of the catch-basin A with their upper ends at a few inches from the lower side of the bars b of the said intakeopening. Although but a single removable sedimentary vessel may be employed, yet I prefer to employ at least two, although three or more may be used when the conditions of the streets contributing to the catch-basin necessitate an increased number. Thesesedimentary vessels have their aggregated'areas of upper open ends of their chambers considerably larger than that of the removable intake-opening D above and are so arranged in relation to the latter that said opening D will be relatively central to the aggregate areas of both open ends g, so that all the discharges from said intake-opening D may be relatively central with the aggregate chambers. When but a single sedimentary Vessel is employed, said intake-opening D will also be larger in area than the area of the open end of the chamber of said vessel, so that similar central discharges may be had from the former into the latter.

Any suitable form of means may be employed for supporting the sedimentary vessel or vessels in proper position with the upper end of the catch-basin, yet I prefer to employ a suitable number of standards H, supported by their base ends 7L from the bottom or door of the catch-basin and projected vertically upward to a suitable distance and provided with suitable horizontal seats I-I', on which the bottom ends of the sedimentary vessel or vessels G may be readily seated, as shown. These seats H may be of any preferred form, yet I at present prefer to make them of broad dat bars h and h2, the latter arranged transverse to the former and with such length as to extend to near the side Walls of the catch-basin, so as to be little short of touching the same. These bars are suitably coupled together by means of coupling-pieces H2, loosely mounted on the upper ends of standards Il by means of central socket h3, provided in the lower side of said couplingpiece H2, and the tenon h4, extended upward from shoulder h5,ipreferably formed by the terminal end edge of the Asaid standards, as shown in Fig. 8. These seats H being readily removable from the upper ends of said standards H may be readily removed therefrom piece by piece as may be required and be as readily replaced.

When street surface water from the streetgutter is being poured into the sedimentary vessel or vessels G G from the intake D above IIO IIS

the Iioatable and sinkable substances, mixed with the street- 1ater and discharged into said vessels, will at first fillthe same, and the inpour of this mixture being continued the water, with the floatable substances, will then flowoutwardly in all possible directions and run in cascade'l form over the edge margins Vof said vessels G, and thereby float out from said vessels the floatable substances, while the sinkable substances-such as sand,broken bits of stone and brick, and other substances heavier than Water-will settle downward and eventually be precipitated within the chamber of said vessel or vessels, there to remain until the vessel or vessels are removed from the catch-basin and dumped therefrom.`

I I are small areas of openings provided in the lower end of each sedimentary vessel, at or near the bottom of the same, through which the water remaining in said vessel and mixed with the heavy sediment therein may percolate and gradually drain the water off from the same,vand thereby reduce the weight of the contents of said vessel, so that the latter when filled or nearly filled may be conveniently removed at will by any suitable means and the contents be dumped therefrom in condition of a moist mass of granular substances.

Jis a grated or open-work vessel, preferably made of woven wire, with meshes about one-half of an inch square. This vessel is the water-screening vessel designed to retain the larger pieces of the iioatable substances which passes out from the sedimentary vesselsinto the catch-basin and allow the water and finer particles to pass below, and it is arranged betweenrthe bottom of the sedimentary vessel and the discharge-opening from the catch-basin. This vessel may be supported by any suitable means and atany preferred distance below the bottom of the sedimentaryvessel and may be made sectional or consist of duplicate .vessels or consist of a single vessel,- as may be preferred or may be found to be advantageous by reason of the conditions which may attendits use. When made sectional or comprising two or more smaller or duplicate vessels, they may be wholly removed, with contents therein, from the basin A and dumped, or when consisting of a single vessel it may be hoisted up to the upper end of the catch-basin and be there held until the contents are removed. Such removal or hoisting of said vessels J may readily be effected when the seating-bars h h2 and their coupling-pieces H2 have been removed away from standards H to outside said catch-basin. y

Located with the catch-basin and between the sedimentary vessels Gand discharge-openatmosphere of the street. Although av trap of any suitable construction may be employed, yet I prefer to use a trap embodying the features of construction shown and de'scribed'in Letters Patent No. 648,207 and-granted to William J. Hough April24, 1900. With'the said Hough trap I have ycombined downwardly-projected intake-openingsk la, which in their aggregate capacity shall equal or nearly equal the capacity of'thegdischargeopening K of the trap. Ball-'form valves L are employed for closing theintake-openings 7c by seating on. suitable ring-form seats M. These seats M are of a metal or alloy which will not rust,and may be of aluminium, brass, bronze, or other suitable material and may be xed in place in the upper end of the' walls of the respective openings lo by any suitable means. My preferred form of construction of this seat-piece M and manner of securing it in place in the upper end of Vwall la of the intake-opening k are shown in Fig.' ll, which construction and manner of securing said seat in place are briefly described as follows: The seat M is made of suitable material, as above described, and has its internal ballseating surface made in whole or part with a concave form of curve m, which is in correspondence with the curvatureof the surface of the ball-valve L, and in its external side are provided the annular groove m' and upper and lower end edge margins n n', which are made on suitable tapering lines as they run downwardly from the upper 'end edge hto lower end edge of the said seat-.piece M and are coated with tin. When the lower half- IOO section of the trap-patterns is being molded inthe sand, the said seat-piece M willbe placed in the suitable internal tapering annular recess provided, respectively, in the upper ends of the walls of the intake-walls with which the pattern is made, and when the mold has been properly completed and taken apart the seat-piecesM will be left in their places in the mold, and when the molten metal is poured the latter will fill'lin the matrix of the mold adjoining the said seat-pieces and also the cavity resulting from the annular grooves m in said seat-pieces and fuse withcthe surface metal of said seat, when said seat will be held securely in place and .have its joint with the metal of the wall of the said intake-opening K water-tight.

. The ,ball-valves L may be of any suitable material and construction; yetI prefer to construct them of thin elastic rubber in the form of' a true sphereand hollow and having its IIO in catch-basins and prevent {ioatable substances incidentally in street surface water from fouling the ball-valves, I provide within the trap relatively back from the intakeopenings 7a and above the valve-seats M the outwardly-extended bay-chambers K3,so situated as to allow the ball-valves L to both rise and move in direction from the dischargeopening, so as to allow the said ball-valves to rise from their seats to such a distance as to permit the full volume of water to readily enter the trap by the way of the respective intake-opening and deliver a full volume from each of the same tothe discharge-openin g K', while the ball-valves themselves will each receive the impact of the rapidly-infiowing water on the portions of the ball over and relatively forward toward the discharge-opening, and thereby be revolved with great rapidity in one direction while the water is washing away the ioatable substances in direction toward the said discharge-openin g. Fi n gers P, properly secured in place and in situation back from discharge-opening K', prevent the ball-valve from being carried to said opening.

The trap K is suitably supported within the catch-basin and communicates by the way of its discharge-opening K' to the dischargeopening C of the catch-basin by means of a suitable pipe or bend N. This pipe or bend I preferably make with a double bend or S form, as shown, so as to produce between the conduit C', communicating from the catchbasin to the sewer, (not shown,) a water seal, which is designed to relieve the ball-valve from excessive pressure from gases which may be generated wit-hin the sewer. This trap K is swiveled in the annular sleeve portion N' of the pipe or bend N and seats on asuitable gasket or packing-ring N2, provided between seating-surface o, adjoining the wall ofthe discharge-opening K', and seating-surface o', formed by the upper end edge of the sleeve portion N', as shown in Figs. l0 and 11, and it may be readily removed from the pipe or bend N by lifting the body of the trap vertically to any desired suitable distance. Access may be had to the body of the trap by removal of the binding-bolts c' '11, shown to be employed for holding the fianges 7a2 7e3 of the respective sections of the trap securely clamped together. By removal of the closingplate N2 from the hand-hole n2, provided at the receiving end of the bend or pipe N, access may be had to the chamber of the latter.

The standards II, supporting the horizontal seats H', on which the sedimentary vessels are supported, are prevented from shifting horizontally in any direction by the coaction of the lower horizontal bars h3 h4 with the horizontal bars 7L h' and the side walls of the catch-basin.

Links Q, provided in their free ends with hook-receiving eyes q and pivoted on opposite side walls of the sedimentary vessels, respectively-each at a point a little above the center of gravity-serve as a means by which hooks of a suitable sling or other suitable adjunct (not shown) of a hoisting device may be readily connected with the said sedimentary vessels for raisin gthem up out from the catchbasins for dumping their contents into a suitable receptacle or place of disposal. Suitable hook-receiving eyes jj are provided in the grated vessel J for service for connecting with the said vessel J the hooks of the same or a similar hoisting device which may be used for hoisting the sedimentary vessels.

It is evident that should the aggregated openings through the removable intake D be much larger than the area of discharge-opening C from the catch-basin the latter would soon be filled to overflowing in cases of heavy rains, and under this condition the fioatable and sinkable substances delivered with the water into the catch-basin as designed could not be separated and would run direct into the sewer, the tloatable portions to float down and out from the sewer and thelatter to settle in the sewer. Therefore I would make the aggregation of the openings in the intake D to be about equal to the opening of the discharge-opening C, leading to the sewer.

By my above-described improvements catchbasins may be provided with efficient and simple means which are adapted to preventlarge stones and large pieces of wood or other substances, cans, and other articles from entering the catch-basin and choking the conduit leading therefrom to the sewer, and also providing a simple and effective means for separating the small floatable pieces of foreign substances and the particles of those substances held in suspension in water from the sinkable substances, the former for passage into and through the sewerand the latter for sedimentation within a removable vessel 1ocated between the street-gutter and the sewer and adapted to be hoisted out from the catolibasin and emptied into a suitable receptacle in a cleanly manner for disposal, as may be preferred. Further, the loatable substances received within the catch basin in their largest pieces may readily be separated from the smaller pieces, the form er to be readily removed at pleasure from the chamber of the catch-basin, while the latter, too small to clog the trap, may readily pass with the water into the sewer,to be fioated out from the same,and, further, the gases generated within the sewer will be prevented by both a tight valve seal and a water seal from escaping to the street.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

l. A catch-basin for sewers having its Walls concave-convex in section and of greater radius than the diameter of the basin, flanges projecting from the vertical edges of said Walls, means for securing the adjacent flanges of the adjoining walls together, and a tapering concrete reinforce for said walls.
