Description

Jan. 11, 1966 e. c. CURRIE ADDITIVE FEEDING MEANS Filed May 15. 1961 IV EN TOR.
M e U c a w m n 5 United States Patent 3,228,049 ADDITKVE FEEBING MEANS Grover C. Currie, 2518 Inverness Road, Charlotte, N.C. Filed May 15, 1961, Ser. No. 109,934 3 Claims. (Cl. 4-226) This invention relates generally to additive feeding means of the type operating to add a modifying supplement to a main stream of liquid in proportion to the flow of the main stream, and more particularly to means of this sort that is uniquely adapted for additive feeding to an intermittently flowing main stream.
A familiar example of intermittent main stream flow is found in the operation of a toilet flushing mechanism which commonly incorporates an overflow standpipe and an associated refill tube for delivering refill water through the stand pipe to the toilet bowl upon each occasion of flushing, and the additive feeding means of the present invention may be employed to excellent advantage for regularly adding a solute supplement to the refill Water upon each operation of the flushing mechanism so as to maintain the toilet bowl clean and continuously deodorized; all as described in further detail below in connection with the accompanying drawings, in which:
FIG. 1 is an illustration, mainly in vertical section, indicating the installed arrangement of an additive feeding means embodying the present invention;
FIG. 2 is a top plan view of the device shown in FIG. 1, without the connection for delivery of refill water thereto, and with the cover for the body member thereof removed; and
FIG. 3 is a side elevation of the FIG. 1 device as seen from the right in FIG. 1.
The illustrated embodiment of the present invention, as seen best in FIG. 1, comprises a body member formed with a conduit portion at 12 and a storage chamber portion at 14.
The conduit portion 12 is characterized in particular by a downwardly opening passageway 16, that may have the top end thereof closed conveniently by a pivot screw 18 provided for securing a cover 26 in place over the storage chamber portion 14. In addition, the conduit portion is arranged with a delivery conduit 22 communicating from the exterior of the body member 1! with the upper end of the passageway 16, and with a diversion conduit 24 branching adjacently from the passageway 16 to the storage chamber portion 14. Both the delivery conduit 22 and the diversion conduit 24 are preferably formed by tubular fittings inserted in the conduit portion 12 to extend therefrom, respectively, at the exterior of the body member 10 and the interior of the storage chamber portion 14, for a purpose that will appear presently.
The storage chamber portion 14 is shaped appropriately for containing a solid state supply of the material from which the desired solute supplement is to be formed for additive feeding; a representative stacked arrangement of circular cakes of such material being indicated at 2.6 in FIGS. 1 and 2. Alternatively, the solute forming material might be in pellet or flake or powder or any other solid state form, as might be most conveniently supplied to and handled in the storage chamber portion 14 in par ticular instances.
It has already been noted above that the storage chamber portion 14 is provided with a cover 28 that is positioned by a pivot screw 18, which allows sidewise displacement of the cover 2i) for opening while tending to maintain it at a closed covering position by suitable tightening. Additionally, the storage chamber portion 14 is formed with a drainage opening adjacent the lower end of the passageway 16 that opens downwardly 'ice from the conduit portion 12. As shown in the drawings, this drainage opening is formed in the illustrated embodiment both by notching the adjacent wall of the conduit portion 12, as indicated at 28, and by shaping the lower face of the body member 10 beneath the conduit portion 12 with a depending circular flange 30 that is proportioned in diameter so that a segment of its cross section also extends into the area of the storage chamber portion 14.
At the depending circular flange 30, a discharge tube fitting 32 is seated to receive downward flow from the conduit portion passageway 16 and drainage from the storage chamber portion 14 as well; and the discharge tube 32 also serves the purpose of locating the body member 11 in operative position as will be noted further just below. Finally, the illustrated additive feeding means of the present invention is equipped with a suitable delivery connection means 34, such as a length of flexible tubing that may be installed on the delivery conduit fitting 22 which is extended exteriorly of the body member 10, as previously mentioned, for this purpose.
As thus constituted, the illustrated additive feeding means is particularly adapted for operative installation in association with a toilet flushing mechanism, as already noted above. The arrangement of such an installation is indicated in FIG. 1, in which the upper end portion of a toilet tank overflow standpipe is represented in dotted lines at 36, while the flushing water supply pipe is similarly represented at 38 with a conventional gooseneck refill tube extending therefrom at 40. The refill tube 40 is often associated with the float controlled ballcock valve (not shown) that is usually installed at the top of the supply pipe 38 for regulating the flow of water to replenish the tank supply at each flushing operation, and the refill tube 40 is normally arranged to discharge in the upper end of the standpipe 36 to deliver thereto a sufficient quantity of water to insure refilling of the toilet bowl after each flushing operation.
When the additive feeding means of the present invention is used, however, the refill tube 40 is displaced from the upper end of the standpipe 36, and the discharge tube 32 of the additive feeding means is inserted thereat in stead, while the flexible tubing 34 installed on the delivery conduit fitting 22 is likewise installed on the displaced refill tube 40, so that the additive feeding means is then interposed between the refill tube 40 and the standpipe 36.
Thereupon, each flushing operation results in directing the refill water through the delivery conduit 22 to the downwardly opening passageway 16 of the feeding means, and such delivery in turn results in bleeding a portion of this refill water through the branching diversion conduit 24 for extracting contact with the solute forming material 26 in the storage chamber 14, from which this extracting portion of the refill water, together with the solute borne thereby, will drain to the discharge tube 32 at which it is returned to the main stream of refill water flowing downwardly from the passageway 16, so that a thus extracted solute supplement is added to the refill water regularly for delivery to the toilet bowl after each flushing.
In order to direct the diverted extracting portion of the refill water effectively into contact with the solute forming material 26, the diversion conduit fitting 24 is preferably extended suitably into the storage chamber 14, as previously mentioned; and the relative orifice size of the diversion conduit 24, as compared with the size of the passageway 16, may be readily proportioned for obtaining the extracting flow of diverted refill water through the chamber 14 in any desired or required quantity.
As to the solute forming material 26 that is used, a wide field of selection is available. The material selected must, of course, be water soluble for the presently de scribed purpose; and, as the aim in this instance is to provide for automatically cleansing and deodorizing a toilet bowl as an incident of its flushing, the material should be selected for its effectiveness in these respects. Otherwise, a wide variety of detergents, soaps, germicides, bactericides, and aromatic scents and the like may be used as a matter of choice.
The present invention has been described in detail above for purposes of illustration only, and is not intended to be limited by this description or otherwise except as defined in the appended claims.
