Description
March 1963 G. N. VALERIOTI ETAL 3,08 LUSH TANKS DISINFECTANT. DISPENSING DEVICES FOR F Filed Jan. 18, 1960 FIG- 2- INVENTOR.
GEORGE N. VALERIOTI VITO R. DE LEO W-Zu 7 2444u';
This invention relates to disinfectant dispensing devices particularly as used in flush tanks or water closets.
More particularly, the present invention relates to-a flush tank deodorant dispenser having a minimum number of moving parts and provision for interchangeability of the dispensing nozzles.
As is well known, the purpose of the aforesaid dispensing devices is to deodorize or neutralize undesirable odors.
The present invention proposes to use a molded polyethylene dispensing tank which is positionable into the flush tank to dis-pense deodorizing liquids into the water of the toilet tank. The bottom of the dispensing tank is provided with an apertureadapted' to receive nozzles provided with variously sized openings to change the size of the dispensing orifice.
Heretofore, the deodorant dispense-rs were provided to deliver a metered quantity of deodorant fluid, thereby necessitating complex and many moving parts resulting in an increase in the probability and possibility of failure of performance. With the present invention, various types of deodorant fluids maybe used, and depending upon the viscosity of the fluid, the nozzle openings may be changed to eifect a control over the quantity of deodorant dispensed.
A further feature of the present invention is the coaction of the nozzle opening with the closure therefor without any intercommunication or entry of the closure or moving parts thereof into the nozzle opening.
An object of the present invention is to provide a deodorant tank fluid dispenser, operative in response to the release of Water from the water tank, with a minimum number of moving parts.
A further object of the present invention is to provide a deodorant tank which isolates the fluid contained therein from any moving parts except at the point of dispensing the same from the nozzle opening.
Yet another object of the present invention is to pro vide a deodorant tank with interchangeable dispensing nozzles, thereby compensating for differences in viscosity of various deodorant fluids.
Yet a further object of the present invention is the provision of an improved deodorant tank fluid dispenser of the above character which is of simple design and construotion, economical to manufacture, and highly efficient in the accomplishment of its intended purpose.
The exact nature, features and advantages of the invention will appear from the following description taken in connection with the accompanying drawing, in which:
FIGURE 1 is a schematic elevation view of a bowl and toilet tank therefore illustrating the toilet tank deodorant dispenser.
FIGURE 2 is a front elevational view of the dispenser with the lower portion thereof partially broken away and shown in section.
FIGURE 3 is a side elevational view of the dispenser shown in FIGURE 2 with the top portion broken away, and
FIGURE 4 is an enlarged front sectional view of a portion of the dispenser shown in FIGURE 2 illustrating the nozzle at the bottom of the dispensing tank.
Referring now to FIGURE 1 of the drawing wherein nited States atent of 3,080,571 Patented Mar. 12, 1953 like reference characters denote corresponding parts, the
improved deodorant dispenser 10 is shown positioned within the receptacle of a toilet tank "or water closet 12 which is covered by the usual cover. As usual, closet 12 is in fluid communication with bowl 14 for the usual purposes.
Turning now to FIGURES 2 and 3 which illustrate the presently preferred mode of practicing the invention, dispenser 10 comprises a tank or receptacle 20 having coupled to the upper end thereof a toilet tank retaining clip 22 and a snap-on cover 24. Coupled by any suitable means to one of the vertical sides 26 of tank 20, preferably a side having the narrower of the two widths, are a pair of float retaining elements or float guides 28 each having an opening guide path therein for movably coupling a float rod 30 having afloat ball 32 coupled to a lower end thereof. At the lower end of tank there is provided an opening for frictionally or fitably retaining a removable nozzle 34 soas to enable the changing and removal thereof.
The base of tank 20 is provided with an inclined surface 36 so as to direct any fluid therein to nozzle 34 for discharge through the orifice in nozzle 34. The shape of nozzle 34 and the size of the orifice will depend upon the viscosity of the fluid in tank 20 so as to enable the proper discharge of the fluid. Accordingly, it is one of the features to provide for the rapid change of nozzles to meet the requirements of the viscosity of the fluid used.
In order to seal the nozzle 34, there is provided a valve seat 38 of rubber or other suitable plastic material which is carried by one end of horizontal arm 40, the other end of arm 40 being coupled to float rod 30 and movable therewith. Valve seat 38 is movable with rod 30 from a normally closed position when tank 12 contains its usual amount of water to an open position when the Water is discharged into bowl 14 so as to discharge the disinfectant contained in receptacle 20. Nozzle 34 does not discharge a metered quantity of the fluid, but an amount the variat-ion of which is not critical thereby eliminating the requirement for complex movable parts. Of course, nozzle 34 may be changed to alter the size of the orifice to control the quantity of fluid discharged. It will also be noted that the valve 38 is operatively associated with nozzle 34 but is independent thereof since it does not enter into nozzle 34, but merely contacts the same for sealing and closure thereof, thereby avoiding any wear of or detrimental effect upon nozzle 34.
While there has been shown What is at present considered to be a preferred em'bobdiment of the invention, it is apparent that many changes and modifications may be made therein without departing from the invention, and it is therefore, intended in the accompanying claims to cover all such changes and modifications as fall within the true spirit and scope of the invention.
