Description
May 3, 1932. B. A HERTSCH GREASE TRAP OR INTERCEPTOR Filed July 25, 1931 till Patented May 3, 1932 UNITED STATES BER-NEAR!) A. HERISCH, 0F ROCKLEDGE, PENNSYLVANIA GREASE TRAP OR INTERCEPTOR Application filed July 23,
This invention has reference to greaseinterceptors and more particularly to greasetraps for application to kitchen sinks, dish washers, and other greasy-water containers or receivers. Such traps are usually designed to arrest grease or other waste matter and accumulate the same while aiming to avoid clogging of the waste water discharge to the sewer or other region of disposal.
Devices of the kind heretofore in common usage are appreciably unsatisfactory. while much diiliculty has obtained in removing the grez se and other accumulations therefrom. r inother objectionable feature associated with such traps is the escape of foul air or noxious gases therefrom, which is not only unhealthy but highly offensive and insanitary, more particularly, in warm weather.
the primary object of my invention is to overcome the noted disadvantages in a simple and effective manner by providing a grease trap, or water refuse interceptor, which is not only thoroughly sanitary but highly ellicient in use.
Another object is to furnish a grease-trap or interceptor for household usage, more partici'llarly, wherein the accumulator or collection receptacle is wholly exterior of the discharge connections and thereby constitutes an outside seal, relative to the drain piping, whereby foul air or gases from the drainage system are prevented from escape by way oi the sink strainer or other inlet.
it further object of this invention is the provision of a grease-trap or interceptor embodying means whereby the normal direction of flow of the waste water is diverted or changed so as to set up a whorling condition in the grease and waste accumulator, with the result that precipitation or separation oi substantially all matter not dilute is established; and, incidentally, much of the waste matter that otherwise would be car ricd into, and through the discharge piping, to disposal becomes emulsified or coagulates and is prevented from passage beyond the trap.
Uther objects and advantages will herein-- after appear or be noted, and, to such ends, my invention consists essentially in the novel 1931. Serial No. 552,644.
construction, combination and arrangement of parts as herein illustrated and described, and thereafter specifically claimed.
In the drawings,
Fig. 1 is a vertical section through one 5;: convenient embodiment of this invention; and,
Fig. 2 is a horizontal section taken as in dicated by the arr-owed line 2-2 in Fig. 1.
Referring more in detail to the drawings the numeral 1 designates a fragmentary sec tional portion of a conventional household sink, axially taken through the usual perforated Waste-water strainer 2; while 3 indicates the customary outlet or trap-attaching nipple, and a the discharge connection to the sewer or other source 0i disposal.
In accordance with my invention I connect to the outlet nipple 3, by meansoi a spilt clamp-coupler 5, with interposition of a suitm able gasket 6, a down-pipe 7 of special con struction, the same being provided at its upper end with a flange 8 whereby it is adapted for connection to the nipple 3 by the clamping-coupler 5. This down-pipe 7, it in to be particularly noted, is provided with a diametric wall or longitudinal partition J that separates the same into down-and-up flow-conduits 10, 11, respectively; while it is also to be remarked that the up-flow portion 11 is entirely closed against entry of waste water from the sink 1, by way of the outlet strainer 2, through the medium of an extension 12 of the flange 8 thereover, in an obvious manner. In other words, the pipe 5,. 7 is separated longitudinally, by the partition 9 and flange extension 12, into paralleling flow-passages 10, 11, of se1ni-circular cross-section.
At a predetermined point below the upper as end of the pipe 7 is a horizontally-directed flange 13 with a downwardly-directed peripheral rim 14 screw-threaded internally, although not essentially so, for reception of a cylindrically-shaped receiver 15 with inso terposition of a suitable sealing gasket 16.
It is to be noted at this juncture, that the trap or receiver 15 is wholly exterior of the pipe 7 and that it is easily removed, by unscrewing, from the flange 13; or, vice versa, n11;
readily coupled thereto, whereby any grease or other matter collected can be removed and disposed of, with a minimum of labor and in an obviously sanitary manner. The trap or receiver 15 may also be provided with exteriorly-located circumferential fins, as indicated in dot-and-dash lines at 17Fig. 1, for cooling purposes; or said fins may be made continuously thereabout for a similar purpose; while said receiver may be otherwise removably coupled to the flange 1821s found most expedient.
The pipe down-flow conduitsecti'on 10 is provided with a grease escape port or outlet 18, at a suitable level below the top of the receiver or trap 15, said outlet functioning to also relieve compressive pressure above the fluid level in the receiver 15 and, at its lower end it has a laterally-directed scoop-like portion 19, functional similar to a turbine vane to set-up a whorling or spiralizing-flow upwaruly of the waste water about the pipe 7, whereby any semi-solid or other matter not carried out by way of the port 18 is directed away from entry into the up-flow conduit 11. In other words, the vane 19 sets up adivergent eddyingflow of the waste discharge, via the conduit 10, into the receiver 15 whereby any contained matter not carried out by the port 18, is outwardly directed in said receiver 15 and gradually piles-up or settles therein, as graphically indicated at 20, with positive assurance of its non-conduction by way of the up-flow passage 11 into the waste-water branch 21 of the pipe 7, which is conventionally joined by a union-coupler 22 to the discharge connection 4.
From the foregoing it will be apparent that with a contrivance such as illustrated and described the passage of floating greasymatter 23 is diverted by way of the port or outlet 18 into the receiver 15, and that other matter 20 of a semi-solid or solid character carried down the conduit 10 is whorled or eddyingly-directed by the vane 19 and settles in said receiver as above set forth. Another feature of note, is that by closing in the upper end of the conduit 11 at 12 above the waste-water branch 21, and consequent creation of an air compression zone thereat,
siphonic-action through the device is efl ectively prevented.
Finally it is tobe noted that I do not limit myself in any way as to the proportions of the several parts, or the materials employer also, it is to be understood, that all such reasonable changes and modifications to adapt my invention for different usage are comprehended as within the scope of the following claims.
Having thus described my invention what I. claim is l. A grease trap or;interceptor-comprising a conduit divided longitudinally into flow and return passages, means at the outlet end of the flow-passage to set-up a whorling discharge, means supporting a receiver wholly exterior of said conduit, and a grease escape from the flow-passage into said receiver.
2. A grease trap or interceptor comprising a conduit divided by a longitudinal partition into flow and return passages, means at the outlet end of the flow passage to set-up a whorling discharge, means remote therefrom closing in the end of the return passage, means removably supporting a Waste receiver wholly exterior of the conduit, and a grease escape from the flow passage into said receiver.
3. A grease trap or interceptor comprising a conduit diametrically divided by a longitudinal partition into down-and-up flow-passages, a scoop-like vane at the lower end of the down-flow passage to set-up a whorling discharge, a diametric partition closing in the upper end of the up-flow passage, a surrounding flange intermediate the upper and lower ends of the conduit adapted for the removable support of a waste matter receiver wholly exterior to said conduit, and a grease outlet from the down-flow passage below the flange aforesaid communicating into the receiver.
1. A grease trap or interceptor comprising a conduit diametrically divided by a longitudinal partition into down-and-up flow-passages, a scoop-like vane at the lower end of the down-flow passage to set-up a whorling discharge, a diametric partition closing in the upper end of the up-flow passage, a surrounding flange intermediate the upper and lower ends of the conduit adapted for the removable support of a waste matter receiver wholly exterior to said conduit, a grease outlet from the down-flow passage below the flange communicating into the trap, and a waste water discharge from the Lip-flow passage above and exterior to the receiver.
5. A grease trapor interceptor comprising a conduit diametrically divided by a longitudinal partition into down-and-up flowpassages, a scoop-like vane at the lower end of the down-flow passage to set-up a whorling discharge, a diametricpartition closing in the upper end ofthe up-flow passage, a surrounding flange intermediate the upper and lower ends of the conduit adapted'for the removable support of a waste matter receiver wholly exterior to said conduit, a grease outlet from the down-flow passage below the flange communicating into'the trap, a waste water discharge from the up-flow passage above and exterior to said trap, and means whereby the trap or interceptor may be coupled to a discharge nipple and the waste-water disposal piping.
