16 therethrough, prefera temporarily submerged by a 'tation of the liquid containing them, are orced in a direction contrary to that which would naturally result in clogging the strainer openings.
With the above general description in view, my invention resides in various arrangements designed to carry out the above objectives and embody the features generally discussed above, as well as other specilic features to be later set forth.
Referring again to the drawin 1 indicates the drain body. This has a s ouldered opening at the top designated 2, and a flange 3 adjacent to the opening which overhangs the side walls of the body, outwardly therefrom, and forms a strengthenin rib for the top of the body. Below the ange 3 and extending outwardly from the side wall of the body is a flange 4 which may be considerably varied in construction, but which is preferably terraced as at 5,'partly to provide securing anchor surfaces for the concrete formation of the fioor, but mainly to direct seepage liquid toward the body.
The flanges 3 and 4 cooperate in holding the drain body in position in the door structureV since, in the event that the body of concrete extends-no lower than the lowermost surfaces of the flange 4, the drain will be prevented rom shifting either up or down, as will be appreciated from inspection of the drawings. Further, the flange 3 reduces chipping of the concrete at the edge of the fitting by reason of overhanging an annulus of concrete therebeneath and strengthening the same.
Associated with the anchor 4 and extending throu h the body wall, are a suitable seepage openings 6 which drain oil any liquid which may accumulate about the body below the flange 3, this seepage discharging into the drain body, and thence to a main outlet to be presently described.
The drain body is provided with an outlet hub. The hub 7 Yis disposed at the bottom of the body. The main discharge opening Referring again to the drawings, 15 is a suitable main inlet closure member i'n the nature of a grate havin enlarged openings ly diverging downwardly to prevent clogging, the outer edges of the grate being seated in the shouldered opening 2, and resting on the shoulder. Below the grate and substantially in intimate contact therewith soy as to catch all materials, whether liquids or solids entering the main grate openings 16, is a hollow conveyor member 18 forming a main liquids and so ids receiving chamber. This conveyor, as shown, has a downwardly converging wall 19, joining a more restricted extension 20 to discharge liquids and solids centrally of the drain body.
may comprise an extension thereof to The'li nids and solids conveys;` dip of the sediment resently shown, t refuse and to if desired, prolow the normal liquids level chamber, formed as will be to prevent agitation of caug provide a water seal. I may, vide a removable extension 20', engaging an supported by the conveyor member 18.
t is to be understood, of course, that the sediment chamber may be fixed or removable, and is 4disposed to catch all materials passing through the conveyor. Fig. 2 illustrates a fixed sediment chamber, comprising the bottom 25 and adjacent sidewalls of the drain body 1 below the liquid level L--L.
In the drawings there is disclosed a" removable sediment chamber, comprising a receptacle 23 in the nature of a bucket, having supporting lugs 24, for resting on the bottom of the drain body. ln this and similar instances, the sediment receptacle brim determines a liquids level L above the general body liquids level L. The sediment receptacle has a suitable number of lugs preferably our, two of which are arrange port abail 27, adapted to lie within the drain body and at one si'de of the conveyor 18 in easily accessible position.
The refuse retention means, as shown in the drawing, are rigidly associated with and include part of the conveyor. As shown, the lower end o the extension 2O has rigid there-` with a downwardly diverging skirt 30. In Fig. 1, this rests on and is supported by a suitable number of inwardly projecting lugs 31, formed on the wall ofthe sediment receptacle 23. The rigidly combined elements may be removed from the body by the use of a handle, comprising a cross bar 28 positioned in suitable registering openings near the top of the conveyor member 18.
The retainer member 30, in order to hold back substantiall all solids while permitting excess liqui s to drain from the sediment receptacle through the body to the main channels, shown as small horizontally extending perforations 33 therethrough. The member 30 cooperates with the sediment to supchamber wall to prevent escape of either sub- 4 merged or {ioating shown, this cooperation is effected by continuous line contact of the outer edge of the skirt with the sediment chamber `wall. ln Fig. 2 the skirt has an impeforate horizontal flange 32, substantially continuously engaging the main drain body wall. when it is desired to discharge fioating liquids, the openings 33 are disposed at the liquids level L as at 33' and below this level.
By the arrangement shown, it will be seen that sediment discharged through the conveyor will be deposited at the bottom of -the sediment receptacle while floating refuse, temporarily submerged, will be wardly by the inclined wall 30, and in rection generally contrary a dito that favoring solids therebetween. As A directed upy 5 discharged through the openin a tendency to clog the openings 33, into the im erforate part of the retention means.
t will be noted that the openings, such as 33, comprising the outlet of the retention means, are of individually lesser area than termines the liquids level L within the drain body. It is desirable, particularly where a removable sediment receptacle is provided, to 'have its liquids level above the level L; as shown, for example, so that buoyant liquids 33 will more readily drain o the top o the receptacle 23, so as not to be removed with the rece tacle.
t is manifest that continued use ofthe u drain without cleaningwill eventually result in blocking the intended channels b accumulated refuse so t at a pool of liqui may be caused to stand bove the main inlet to the drain body for ,considerable period. This is obviousl undesirable. To reventv this, I provide t e auxiliary inlet an by-pass discharge, previously mentioned.
The by-passin arran ment, as shown, comprises a suita le num r of small openings 17, outwardl from the larger opening 16, preferbly ownwardlg' divergin in shape to revent clo ging y solids uch o nin p ie outward y from the to edge of t e mam inlet chamber, so as to disc arge directly into the body without passing through the sediment chamber, the retainer, etc. Thus, assumin the normal passa s are clogged, li uid rom the surface to be rained wil pass t rough the opening l'', and run directly down into the drain outlet 10. The auxiliary inlet openings are much smaller than the main inlet openings, hence, although they will serve to drain the surface above of liquid so long as this surface is kept clean of refuse, the device acts as a tell-tale to inform the attendant when the solids retention means are obstructed, because liquid will run through the ,openings 17 much more slowly than throu h the normal channels.
The openings 1g have a further function in that they will discharge all volatile gases accumulatin within the drain body and likely to stand a ut the conveyor 18, where they might cause an explosion 1f ignited when the various parts are removed for cleaning.
The conveyor, previously desi has restricted extension or dip-pipe roper formed at which enters the se iment chamber to a point below the liquids level thereof, making an air seal and causing )he ated 18,
dischar into the sediment chamber to be below t e liquids level, thus causing light oils and other buoyant liquids, gasoline for example, to overflow the sediment receptacle. In ot er words, oil and gasoline remaining from previous discharges at the top of the sediment chamber is immediately washed out and does not become emulsiiied with the water.
The bottom or outlet end of the extension, 20' may also extend some distance below the lowermost outlet holes of the retainer, and thus comprise the lowermost portion of the retention means. Thus, submerged solids accumulating within the sediment chamber may reach and obstruct the outlet end of the extension before reachingand obstructing the retainer outlet holes, and preventing formation of a static head of water within the retention means and`beyond the extension 1 P The outlet of the extension 20 is preferabl of lesser area than that of any of the out ets beyond the extension thereby creating an easy discharge through the drain, preventing undue disturbance of solids held therein, and also preventing undue rise of the liquids level.
The retainer member and extension or dip pipe, and incidentally all the tubular bodiesof the illustrated constructions, are prefer- 4ably circular in cross section, but may be of anv desired shape,
uare for example. ln the above description, the terms floating and submerged have been used extensivel as modifying solids. It will be understoo however, that in certain instances the parts of the solids retention means function without regard to the character of solids. The terms floating and submerged as ap-` pearing in the claims are, therefore, in general not to be construed as limiting but` rather explanatory terms.
