Application March 11; 1939, serial No. 261,391 v 9 Claims. (o1.;1

This invention relates generally to surface drains, and more particularly to drains which prevent refuse and the like from passing to the main drain line to which the drain is connected.

means for directing the how of liquid to the center of the restraining means or bucket. I

- It is accordingly, an object of my invention to overcome the above and other defects in drains and more particularly to provide a drain which is simple in construction, efiici'ent in operation,

cheap in cost, and easy toinstall.

'Another object of my invention is to provide a surface drain wherein means are provided for indicating the clogging of the straining member of the drain Without flooding the drained surface. Another object of my invention is to provide a surface drain which has a cover designed to meter the flow of fluid to the drain and to direct the drained water to the central portion of the drain structure. Another object of my invention is to provide a simple means for removing the strained refuse from the drain,

Another object of my invention is toprovide a surface drain which has all parts thereof remov ablcthrough the inlet opening.

Another object of my invention is'tofprovide surface drain wherein the parts thereof are. so, disposed that a metering aperture is provided to restrain solids but permitting a predetermined flow of fluid therethrough.

Another object of myinvention is'to provide a surface drain whereinthe metering aperture: below the surface of the drain cover and is pro tected by the initial straining means orperforated cover. d d

Other objects of my invention will become evident from the following detailed description, taken in conjunction with the accompanying drawing, in which Fig. l is a plan view with parts broken away of my novel surface drain.

Fig. 2 is a side elevational view with parts broken awayofmy novel surface drain connected td'a drain line.

-R'eferring to the drawing, my novel surface drain comprisesgene'rally an outer cylindrical member I having an inlet and an outlet, a solids retaining-member 2,, and a cover 3 having tapered slots 4. Theg'outer cylindrical member I has an offset portionv Er providing a shoulder 65. An outwardly 'and upwardl y, extending portion I with a plurality of projecting members 8 provide anchoring means for the drain and furthermore directs theseepage into the drain line through the aperturesflin thee-cylindrical member I. The

bottom portion ID of the'cylindrical member I is flanged inwardly and an interiorly threaded aperture I i is formed to engage a drain line l2 to drain the liquid fromthe surface of. the floor to I be drained.

The solids'retaining member 2 is cup-shaped in form and-the sidesthereof have apertures I3 to U permit the lateral flow of fluid passing through the drain. while retaining the solids in the solids retaining member 2-. A few' small apertures I I are disposed in the bottom of the solids retaining member 2 to permitbetter flow of fluid throughthe drain. The solids retaining. member 2 is. disposed in spaced relation with the side and bottom portions of the cylindrical member l by means of annular ring member I5 and brackets I5 connecting thering member I5 and the outer surface of the'solidsretainingmember I. The annular ring member I5 rests on the shoulder 6 of the cylindrical'member I and Supports the solids retaining-member 2 in spaced relation with the sides and bottom of the cylindrical member I. A

slotted cover 3 has a wide rim or border portion I! extendingto the interior surface of the solids retaining member 2 in order'that the fluid will not flow directly to the drain line I2 without passing through the solids retaining member 2.

' An annular shaped aperture I 8 is provided be tween the bottom portion of the cover 3 and the top of the retaining member 2 in'o'rder that the fluid may'pass to th'e'drain line I2 when the apertures I 3 ofth'e' solids retainingmember 2 becomes clogged. The wldth of this aperture I8 is such that a noticeable amount of fluid will be backed up to noticeably cover the slottedcover 3 inorder that? notice maybe given that'th'e solids retaining member 2 is clogged and must, be removed. The annular aperture I8 is protectedby the cover 3 and is such width that ordinary solids will not pass therethrough. The tapered slots 4 in the cover 3 tend to direct the fluid passing intovthe drain directly to the center of the solids retaining member 2 thereby increasing the eficiency of the solids retaining member 2 in that the solids will strike an unperforated portion of the solids retaining member 2 and the fluid will move outwardly laterally therefrom. By removing the cover 3, it will be evident that the solids retaining member 2 may be very simply removed. I g I In operation, the tapered slots 4 in the cover 3 causes the fluid entering the drain to'flow to the center of the solids retaining member 2 wherein it flows laterally outwardly through the apertures l3, the solids being retained in the solids retaining member 2. When the apertures [3 of the solids retaining member 2 become clogged, the fluid will overflow the solids retaining member .2 and pass through the annular aperture I8 to the drain line l2. The annular aperture l8 will not permit solids to pass therethrough and it will further cause the backing up of the fluid so that it will overflow-the cover 3 and give notice that the apertures l3 are clogged and that the solids retaining member 2 must be removed. The removal of the solids retaining member 2 is evident from inspection of the drawing.

It will be evident that I have provided a surface drain which is simple in construction, easy to clean, efficient in operation, and operable after clogging of the solids retaining member 2 with means for giving notice of the'clogged condition of the retaining member.

Various changes may be made in the specific embodiment of the present invention without departing from the spirit thereof, or from the scope of the appended claims.

What I claim is:

1. A surface drain of the class described, in combination, a member having an inlet and an outlet, a solids retaining member disposed centrally of said first mentioned member having the sides thereof perforated to permit the lateral flow of fluid, a slotted cover for said first mentioned member disposed to provide an annular aperture between the top of the solids retaining member and said cover whereby fluid may pass therethrough to the outlet of said first member 2. A surface drain as set forth in claim 1 wherein the slots in said cover are tapered to direct the fluid to the center of said solids re.- taining member.

'3. A surface drain as set forth in claim I wherein said first mentioned member has an outwardly extending flange to direct seepage to said outlet of said first mentioned member.

,4. A surface drain of the class described, in combination, a cylindrical member having an inlet and an outlet, a solids retaining member disposed in said cylindrical member in spaced relation with the sides thereof, and a slotted cover having a wide rim portion whereby fluid can pass only to said solids retaining member, said cover and said solids retaining member being disposed to provide an annular aperture for the flow of fluid to said outlet of said cylindrical member when said solids retaining member becomes clogged I 5. A surface drain of the class described, in

perforations in said solids retaining member become clogged.

6. In a surface drain, in combination, a cylindrical member having an inlet and an outlet, said cylindrical member having the upper portion thereof offset to form ashoulder, a solids retaining member having outwardly projecting portions engaging said shoulder of said cylindrical member to support said solids retaining member in spaced relation with said cylindrical member, and a perforated covercarried. by saidout-v wardly projecting portion of said solids retaining member disposed to direct all fluid into said solids retaining member, said cover and the top of said solids retaining ,member forming an annular aperture whereby fluids may flow therethrough to said outlet when the apertures in said solids retaining member become clogged.

7. A surface drain as set forth in claim ,6 wherein the slots in the cover are tapered to direct the fluid to the center of saidsolids retaining member. 1 v

8. In a surface drain, in combination, a cylindrical member havingan inlet and an outlet and an inner shoulder on the upper. portion thereof, a solids retaining member having perforated sides and an outwardly projecting portion for engaging said shoulder to support said solids re taining member in spaced relation with the in-- the inlet of said cylindrical member, the widerimmed portion of said cover and the top of said solids retaining member forming an annular aperture for the flow of fluid to said outlet of said cylindrical member when the perforations of said solids retaining member are clogged while retaining solids in said solids retaining member.

9. In a surface drain, in combination, a cylin-' drical member having an inlet and an outlet and an inner shoulder on the upper portion thereof, a solids retaining member having perforated sides and an outwardly projecting portion for engaging said shoulder to support said solids re- 1 taining member in spaced relation with the interior of said cylindrical member, and a wide rimmed cover having slots therein disposed over the inlet of said cylindrical member, the rim portion of said cover being disposed to direct,

an annular aperture for the flow of a predeter mined amount of fluid to said outlet when the perforations of said solids retaining member are clogged while backing enough fluid to give notice that the perforations are clogged.
