DISPENSING MECHANISM FOR LIQUID DEODORANTS Filed Dec. 14, 1959 PQUL CZ FLLMQN INVENTOR ATTORNEY 3,002,197 DISPENSING MECHANISM FOR LIQUID DEODORANTS Paul C. Tillman, Los Angeles, Calif., assignor to Wayne H. Baker, Los Angeles, Calif. Filed Dec. 14, 1959, Ser. No. 859,442 3 Claims. (Cl. 4-225) This invention relates to a dispensing mechanism for liquid deodorants, and is used particularly on toilets and urinals for the purpose of dispensing a small quantity of liquid deodorant into the toilet or urinal at the end of each flushing period.
An object of my invention is to dispense a small quantity of liquid deodorant into the flush pipe, chamber, or receptacle of a toilet or urinal, the liquid deodorant being dispensed automatically and activated by the flush water in motion.
Still another object of my invention is to provide a novel dispensing mechanism of the character stated, which will dispense a small quantity of liquid deodorant at the end of each flushing period or flow to obtain maximum efiiciency from the deodorant. Also the deodorant will be dispensed in the required quantity independent of the quantity of the flush water.
Still another object of my invention is to provide a. novel dispensing mechanism of the character stated, which is simple in construction and easy to manufacture, which has no moving mechanical parts, which is easy to install, and which will function correctly over long periods of time.
Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.
In the drawing:
FIGURE 1 is a side elevation of my dispensing mechanism with parts broken away to show interior construction.
FIGURE 2 is a fragmentary side elevation of the deodorant supply pipe with parts broken away to show interior construction.
FIGURE 3 is a perspective view of the urinal upon which my dispensing mechanism may be placed.
Referring more particularly to the drawing, the usual urinal or toilet I is provided with a water supply or flush pipe 2. This pipe is normally empty until the flush valve (not shown) is opened, and thereafter the pipe is filled with flowing water. The amount of water flowing through this pipe will vary with different installations and pressures, but the amount of deodorant should remain constant irrespective of the quantity of flushing water. My dispensing mechanism 3 consists of an elbow 4 which is fixedly mounted in the flush pipe 2 by means of a screw fitting 5 which threads into the wall of the pipe 2. A cap 6 screws onto the upper end of the elbow 4 and this cap is provided with a small intake hole 7 through which a quantity of water flows when the toilet or urinal is flushed. An outlet or drain port 8 is provided at the lower end of the elbow 4 and permits the deodorant to drain into the pipe 2 at the end of the flushing period, as will be subsequently described. A jar or container 9 is attached to the wall 10 by means of brackets 11 and is mounted adjacent to the flush pipe 2. The liquid deodorant partially fills the jar or container 9 and the upper end 12 of the jar is partially evacuated, and thus atmospheric pressure will hold the liquid in the container 9 until the vacuum at 12 is partially relieved by the addition of a small bubble of air. A deodorant supply pipe 13 extends from the bottom of the container 9 to the elbow 4 and is attached to the elbow by means of a pressure fitting 14. A vent pipe 15, having a small tes atent orifice at its open end, extends into the pipe 13 below the container 9. This vent pipe is for the purpose of relieving any vacuum in the pipe 13, as will be subsequently described. A small metering orifice 16 is provided in the upper end of the pipe 13 and within the container 9. The purpose of this small metering orifice is to reduce the quantity of liquid which will be fed into the pipe 13 each time a bubble of air passes through the liquid and thence into the partial vacuum 12, thus reducing the deodorant feed to the small amount which is normally required. The pipe .13 is held on the lower end of the container 9 by means of a cap 17 which fits onto the lower end of the container, as shown.
In operation When the flush water travels downwardly through the pipe 2 a small amount of this water will enter through the hole 7 and thence into the elbow 4 and also into the pipe 13 for a distance less than where the vent pipe 15 enters the pipe 13. The velocity of the flushing water will trap a bubble of air ahead of it since the pipe 13 is filled with air prior to the flushing step and will force that air upwardly in the pipe 13, and will move the air bubble in the pipe 13 ahead of the column of water which rises therein, due to the pressure of the flushing water. A small amount of this air will be vented out through the vent pipe 15 and the remainder will pass through the metering orifice 16 and thence through the deodorant liquid in the container 9, and will pass into the partial vacuum area 12. The partial vacuum at 12, being now partially relieved, will permit a small quantity of liquid to pass through the metering vent 16 and will flow downwardly through the supply pipe 13 towards the elbow 4. As long as the flush water is flowing through the pipe 2 the deodorant will be held in the supply pipe 13 away from the elbow 4 due to the column of water in said pipe. However, as soon as the flushing ceases the deodorant liquid can flow downwardly through the pipe 13 following the water column therein, and thence into the elbow 4 and out through the drain port 8. The deodorant then flows down through the flush pipe 2 and into the toilet or urinal. Since the flushing water has already passed out the small quantity of deodorant is more effective and will not be diluted. Any vacuum in the supply pipe 13 will be relieved by the vent 15 which permits air to flow into this pipe.
Having described my invention, I claim:
1. A dispensing mechanism for liquid deodorants for toilets and urinals including a flush pipe, an elbow fixedly mounted in said flush pipe, said elbow having a small hole at the upper end thereof, and an outlet port at the lower end thereof, a deodorant container, a pipe extending from the deodorant container to said elbow, means attaching the pipe to the elbow, and a vent pipe extending into said supply pipe, the vent pipe being positioned adjacent the deodorant container.
