J. HEINKEL GREASE INTERCEPTOR 2 Sheets-Sheet 2 Filed Dec. 11, 1930 Inventor MAilorney Patented Nov. 29, 1932 UNITED STATES PATENT oFFiea JOHN HEINKEL, OF ROCK ISLAND, ILLINOIS GREASE m'rnncnrron Application filed December 11, 1930. Serial No. 501,490.
" packing-houses, soap factories and similar institutions, for the purpose of separating the grease and other matter of light specific gravity from the waste waters. In machines of this kind as now constructed there is danger of the waste material being carried along by the force of the stream, including the grease and other material of more or less value, much of which is carried into the drain, thus defeating the purposeof themachine. v
One purpose of the present invention is to provide means for retarding the stream when it'first enters the machine, and causing the same to disintegrate, in condition for a ready separation ofthe lighter and heavier portions of the contents in the continuedmovement of the liquid through the machine. To accomplish this two compartments are provided, thefirst of which is adjacent to the intake, and contains the retarding devices, and the other of which provides the means for the further separation of the parts, and removal of the grease.
Another object of the invention is to pro vide means for a more rapid movement of the heavier matter contained in the liquid toward the discharge point, for expulsion from the machine.
Incidental to the retarding of the current is provided means for the removal of broken dishes, oyster shells, and other scrap matter before it enters the main part of the machine. Another purpose thereof is toprovide a cover for the machine which will be selfsealing and which will also be fitted with means for preventing the liquid from being forced between the receptacle and cover thereof. I
These, and other features and advantages of the invention will more fully appear from the following specification, taken in c0nnection with the accompanying drawings, in which Fig. 1 is a plan view of the invention, with the cover partly broken away.
Fig. 2 is a medial longitudinal section thereof.
Fig. 3 is a cross-section on the broken line 3-3 of Fig. 2; v
Fig. t is a fragmentary view similar to Fig. 9., showing a modified form of the invention.
Fig. 5 is an enlarged detail of a portion of the casing and cover connected therewith.
The reference number 1 indicates a casing of substantially rectangular form, comprising a receptacle for the passage of a volume of water containing waste material. Said receptacle is divided into compartments 2 and 3 by'means of a partition 4., held removably G5 in place by pairs of lugs 5 fixed to the walls of the casing. The downward movement of the partition is limited by pins 6 in theends thereof, engaging the upper pairs of lugs.
' In the end wall of the compartment 2 is an intake connection 7, through which the liquid passes into the machine, flowing first over a plate 8 and downwardly between an apron 9 on said plate and'the partition 4; into r a pocket 10, in which the stream is diverted d upwardly beneath the plate 8 and downwardly into the lower part of the compartment 2. The floor of said compartment is curved,
as at 12, and the current of liquid is directed thereby through a space beneath the parti- S ticn 4: into the compartment 3. The apron 9 extends downwardly into the pocket 10, and the plate 8 and apron 9, partition 4: and pocket 10 cause the stream of water and waste material entering the machine to follow a winding course, correspondingly slowing the stream down, and breaking up the component parts thereof.
The pocket 10 serves further as a trap, in which are collected fragments of broken crockery, glass-ware, oyster-shells, and similarscraps, to prevent their entering the compartment 8, from which their removal would be more difficult, and in which they would be likely to block the outlet. The movement of such scraps out of the pocket with the current is interfered with by a flange 11 on the edge of the pocket. The pocket 10 is preferably attached to the partition 4 so as to be removed therewith for the purpose of cleaning out said pocket. This is done after the removal of the plate 8, which is supported on lugs 13.
In leaving the compartment 2 the shape of the floor 12 causes the current to move in the direction of a baffle-plate 15 in the compart ment 3, tending to split such current, and further separate the waste elements contained therein. The warmer portions there of and parts of lighter specific gravity are directed upwardly, causing such parts to gather upon the surface of the liquid in the compartment 3, from which they can be removed. The cooler parts of the current, with the dross, pass downwardly beneath said battle and along the inclined floor 16 of the compartment 3 to an outlet at 17, connecting with a vertical discharge pipe 18, with an outlet opening at 19. The current passes outwardly through said opening to a suitable drain or sewer. The bottom of the compartment 3 is formed of a series of troughs :20, increasing in depth to the lower ends thereof.
Said troughs are preferably of angular formation, as shown, and afford no place for the sediment in the outwardly flowing stream of water to become deposited or accumulate. This aids in the free movement of the current, and in preventing the outlet from becoming clogged by the foreign matter in the water. One end of the machine is supported on the bottom of the discharge casing, at 21, and the other end is provided with legs 22, attached to the bottom of the compartment 2.
The upper edge of the casing 1 has an enlargement 24, in the upper face of which is a channel 25, receiving a rib 26 on the lower face of a cover 27. Said rib is preferably wedge-shaped as shown, and adapted to seat itself snugly in a plastic packing 28 contained in the channel 25, forming a tight seal entirely around the upper edge of the casing. The seal is rendered more complete by reason of the fact that the channel and co-acting rib have no angular corners, which frequently interfere with making a tight connection. The lower face of the cover 27 is also provided with a downwardly projected flange 29, extending around the inside of the casing, and forming a splash-apron, to prevent any of the contents from being forced into the joint between the casing and lid. Projecting from the edges of the cover 27 are perforated lugs 30, containing screw-bolts 31, which also pass through perforated ears 32 on the edge of the casing 1, and are held in place by nuts 33. hen the machine is in operation the cover is kept securely in place, but when it is desired to remove any of the contents the cover is detached.
In Fig. t is shown a form of the machine in which the partition and pocket are formed i11- tegrally, and comprise an upper partition portion 34 and curved pocket 35 projected downwardly therefrom, and provided with the curled edge 36. The partition and pocket are further connected at their edges by vertical bars 37, slidable in pairs of lugs 38 fixed to the walls of the casing 1, the pocket being further supported by lugs 39. The operation is substantially the same as in the form before described, except that there is less resistance to the movement of the stream in the latter showing.
he screw-bolts 31 are preferably countersunk in position, making it possible to install he machine below the floor of a building, with the upper face of the cover flush with the floor.
Other changes can be made in the arrangement and manner of operation of the invention besides those pointed out herein, without departing from the spirit of said invention.
What I claim, and desire to secure by Letters Patent, is:
1. A grease-trap comprising a receptacle provided in one end with an intake for liquids, and at the other end with a discharge opening, a partion dividing said receptacle into two compartments communicating beneath said partition, a pocket supported by said partition and removable therewith, an apron for directing the movement of a stream of liquid from said inlet into said pocket, and an inclined corrugated floor in the opposite end of the receptacle having an incline in the direction of the discharge opening.
2. A grease-trap comprising a receptacle provided in one end with an intake and in the other end with a discharge opening, a partition dividing said receptacle into an in take compartment having a semi-circular floor and a discharge compartment having a floor sloping in the direction of the discharge opening, a pocket supported by said partition in the intake compartment and provided with an angular flange at its free edge, an apron projected inwardly and downwardly from said intake into said pocket, tending to direct a stream of liquid matter against said partition and downwardly into and through the pocket and beneath said apron to said semi-circular floor, and a bafile-plate in the discharge compartment positioned in the line of movement of said stream as it comes from said first-named compartment.
In testimony whereof I affiX my signature.
JOHN HEINKEL.
