DRAIN-TRAP.
Application filed June 20, 1913.
To all whom it may concern Be it known that I, HERMAN A. POPPEN- HUsEN, a citizen of the United States, and a resident of Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Drain- Traps; and I do hereby declare that the following is a full, clear, and eXact description thereof, reference being had to the ac companying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to improvements in drain traps, and particularly to that class of drain traps adapted for use in connection with the floors of buildings or garages designed to accommodate motor or other vehicles, and adapted to receive water used in the washing of vehicles and the dirt, oil or greasy substances and foreign matter resulting from the washing process, or which may drop from the vehicles or the like.
Difficulty is often experienced in garages or like structures designed for the housing and maintenance of motor or other vehicles, resulting from imperfect provisions for disposing of waste water, oil and other substances which ordinarily accumulate upon the floor. A portion of this waste matter ordinarily assumes the form of a heavy, greasy mixture of sand, dirt and oil, which tends to adhere to the walls of the drain pipes, restricting the passage of sewage or waste materials and often completely clogging the pipes. The device herein described and shown, and which is constructed in accordance with my invention is designed to eliminate these difficulties, and to insure the proper operation of drain pipes and vessels into which they discharge, and the separation of the oil or lighter materials from the water and sand and dirt or relatively heavy materials.
My invention consists in the matters hereinafter described and more particularly pointed out in the appended claim.
In the drawingsFigure 1 is a top plan view of the device embodying my invention; Fig. 2 is a view in vertical cross section of my device.
Referring to the drawings, the device therein shown, and which is made in accordance with my invention, comprises in its construction a main or stationary receptacle or outer vessel A of metal or other suitable material having side walls which are by Specification of Letters Patent.
Patented Feb. 9, 1915.
Serial No. 774,745.
preference cylindrical and a bottom wall or base. This main or outer vessel is open at its upper end and is provided at the margin of the opening with a laterally extending peripheral flange a. The said flange a is embedded within the floor B or below the surface of the surrounding material which may be in the form of concrete or other suit able material, and has its upper surfaces, by preference, substantially flush with the surface of the floor. The floor is preferably constructed of concrete, as suggested, and forms a surface which is sloping or slightly inclined toward a central point, at which central point the drain trap is located, the same being embedded within the earth beneath the floor. The cylindric wall of the outer or stationary receptacle A is provided with a discharge opening A having the form of a horizontally extending pipe connection C. The said discharge openingis located between the bottom wall and the upper margin of the receptacle and, by preference, substantially midway between said top and bottom of the receptacle, and communicates with the sewer through a drain pipe C connected therewith.
The receptacle is partially closed at its top by means of a cover plate D having a diameter slightly greater than that of the interior diameter of the receptacle. This cover plate is removably retained in position by means of an-annular shoulder a formed in the upper, and inner margin of the receptacle, said shoulder and the corresponding annular recess being of a depth equal to the thickness of the cover plate. The up per surface of the cover plate is thus flush with the upper surface of the annular flange a when the cover plate is in position. The cover plate is provided at its center with a concentric aperture (Z within the margin of which is also formed an annular shoulder d and corresponding annular recess, there being an added thickness of metal provided immediately below or in position to form the grate-supporting flange or shoulder d. Within this aperture cl and removably retained and supported by means of the shoulder or inner annular flange d is a circular grating E consisting of a ring 6 engaging the shoulder at and a plurality of parallel gratebars e integral therewith and forming a plurality of openings therebetwecn. The thickness of the grating E is such that when retained within the annular recess and supportedby the shoulder d its upper surface is flush with the upper surface of the cover plate D.
Within the receptacle A is a removable vessel or receptacle F, the same having, by preference, substantially the same shape as that of the receptacle A. The diameter of the inner receptacle F is considerably less than the diameter of the larger receptacle, there being formed an annular space between the peripheral or side walls of the outer and inner receptacles. The inner receptacle rests upon the bottom of the outer receptacle A and is preferably in concentric relation to the cylindrical peripheral wall of said outer receptacle. The vessel F is open at its upper end, the upper margins of its side walls terminating below the top of the receptacle A and above the level of the top of the discharge opening A.
The receptacle F is provided in its peripheral wall with an opening F, the same being located substantially the same distance above the bottom wall of the receptacle A is the discharge opening A. Extending downwardly across or over the aperture F within the receptacle is a baffle plate G, the same consisting of a sheet of metal 9 secured in a vertical position to the side wallof the inner vessel F by preference above and at each side of the aperture C. The space thus formed between the vertical or upwardly and downwardly extending portion of the baffle plate and the adjacent portion of the wall is closed at the upper endor above the opening F by means of a horizontal portion 9 integral with said vertical, portion and provided with a curvilinear flange g abutting against the inner surface of the wall at a point between the upper extremity of the aperture F and the upper margin of the receptacle F. A plurality of rivets h extending through the flange .g and the wall of the receptacle securely hold the shield in position. The bottom edge of the baffle plate G is below the level ofthe bottom of the opening F and below the level of the discharge opening A, and the liquid contained in the inner vessel or receptacle is thus enabled to form a liquid seal between. the plate G and the opening F adapted to permit the flow of liquid or materials heavier than oil or grease through the opening F and to prevent the flow of liquid or materials lighter than the water or liquid which forms the liquid seal. The relatively light materials, such as oil and grease and scum as well as the sand or other substances heavier than the liquid forming the seal, are thus retained in the inner receptacle, and may be readily emptied when desired, by removing and dumping the inner receptacle The vertical portion fif h, sh el or afl efw fi en t d a sheet in the drawings, terminates substantially midway between the lower margin of the aperture and the bottom wall of the vessel.
. The operation of this device is as follows: The waste water, together with the sand or dirt and oil or other greasy substance is carried over the floor by reason of the inclination of the same, and passes through the grating E into the receptacle F. The sand, dirt and other heavy substances, such as that formed by the mixture of the sand and oil, will be deposited upon the bottom of the receptacle. The water thus flowing into the receptacle is free to flowfrom the receptacle through the aperture F and into the space between the walls of the outer and inner receptacles and from thence to the sewer by way ofthe discharge opening A. The oil, however, which enters the receptacle F being in liquid of less specific gravity than that of the water will float upon the surface of the water and be prevented from passing from the receptacle by reason of the vertical baffle plate. Whenthe discharge into the drain trap ceases, the relatively heavy liquid contents will assume a normal level substantially coinciding with the lowest point of the aperture F, and by reason of the fact that the shield or baffle plate extends some distance below the normal level, a water seal is formed which effectively prevents the oil and other substances lighter than water floating upon the surface of the water from escaping from the receptacle. It is to be noted also that the combined area of the openings within the grating E is considerably less than the area of the aperture F, thus the possibility of the liquid overflowing the receptacle F is eliminated.
The inner receptacle F may be removed at desired intervals and emptied by removing the cover plate D. In replacing the receptacle F, it is obviously not essential that the aperture F be arranged opposite the dis charge outlet A for the reason that the space between the walls of the outer and inner receptacles is sufficient to provide for the transmission of the liquid flowing from the aperture F of the inner receptacle to the said discharge outlet A.
' An advantage of the construction of a drain trap embodying my invention is the application of an inner receptacle which can be easily removed at frequent intervals for purposes. of emptying and cleaning. This feature adds greatly to the cleanliness and proper operation of the trap, in that the heavy substances as well as the oil are eflt'ectively collected and retained within the removable receptacle, thus the remaining parts of the trap are left free from waste material. Itis obvious that the labor in cleaning a drain trap constructed in accordance with myinvenutn and including thisfeature, is greatly lessened. A further advantage is the use of the drain trap as a means for separating by gravity the oil from sand, dirt or other heavy material which would sink to the bottom of the receptacle, leaving the oil floating upon the surface of the water within the receptacle. Upon lifting the re ceptacle from the outer receptacle the oil can be removed and by proper treatment be again used.
The details of construction of my device may be materially modified without departing from the spirit of the invention, and I do not therefore desire to be limited to the structure herein illustrated and described except in so far as specifically set forth in the appended claim.
I claim as my invention A drain trap, comprising an outer receptacle provided with a discharge opening in the side wall thereof, an inner receptacle located within and resting upon the bottom wall of said outer receptacle and there being a space formed between the side wall of said receptacles, said inner receptacle being provided with an inlet opening at its top and a discharge opening in its side wall;
the discharge opening of said outer receptacle being located below the inlet opening of said inner receptacle, a removable cover plate extending over the top of said outer receptacle and being out of contact with said inner receptacle, said cover plate being of a size to permit the removal of said inner receptacle from said outer receptacle and provided with an inlet opening communicating with the inlet opening of said inner receptacle, and a baffle plate located within and secured to the side wall of said inner receptacle and extending over and spaced from the discharge opening in the side wall thereof; said baflle plate having its lower end terminating below the discharge opening of said receptacle.
In testimony that I claim the foregoing as my invention I aflix my signature in the presence of two witnesses, this 11th day of June A. D. 1913.
