BY ma DISINFECTANT DISPENSER Freeman C. Majo, Canal Fulton, Ohio, assignor of fifty per cent to Jerald J. Keplinger, Orrville, ()hlo This invention relates to new and useful improvements in devices for supplying detergent to water supply apparatus and the primary object of the present invention is to provide a means for supplying a detergent to the water within a flush tank. I 1
Another important object of the present invention is t provide a detergent dispenser that is automatically actuated to supply a detergent in response to the lowering of the liquid level in a flush tank as the water in the tank is employed during a flushing operation.
A further object of the present invention is to provide a detergent dispenser for flush tanks that is quickly and readily applied to the top of a flush tank to replace the conventional top wall or closure for a flush tank.
A still further aim of the present invention is to provide a disinfectant dispenser of the aforementioned character that is simple and practical in construction, strong and reliable in use, small and compact in structure to occupy very little space within a flush tank, inexpensive to manufacture and otherwise welladapted for the purposes for which the same is intended.

nitd States Patent() Figure 14 is a perspective view of the valve member used with the form of the invention shown in Figures 11 and 12.
Referring now to the-drawings in detail, and more particularly to Figures'l through 6, inclusive, wherein for the purpose of illustration, thereis disclosed one embodiment of the present invention, thenumeral 10 represents a substantially rectangular flush tank cover or reservoir having a recess 12 at one end that is provided with a filling opening 14 normally closed by a closure plug 16, as shown best in Figure 6 of the drawings.
' The bottom wall of the reservoir 10 is provided with two internally threaded nipples 18 and 20 that are selectively capable of receivably engaging a closure plug 22. The nipples 18 and 20are also capable of receiving the upper externally threaded end of a vertical tube or conduit 24 having a lower discharge end 26.
Upper and lower transverse bores 28 and 30 are provided in the conduit 24 and rotatably receive therein the cylindrical transversely apertured portions 32 and 34 of upper and lower valve members 36 and 38. The valve members 36 and 38 include laterally projecting shank portions 40 and 42 whose outer ends carry floats 44 and 46. The shank portions 40 and 42 also carry stop pins 43 and 50 that limit vertical swinging movement of the valve members.
A plurality of straps 54 rest against the undersurface of the bottom wall of the reservoir 10 and suction cups 56 and 58 are suitably attached to or are integrally formed with the ends of the straps and removably adhere to the reservoir 10. The cups 56 and 58 of each strap are spaced apart sufficiently to receive the upper edge of the peripheral wall of the flush tank T, and thereby confine the reservoir over the tank.
The reservoir is preferably constructed of a material resistant to the harmful characteristics of a detergent, such as plastic, thereby prolonging the useful quality of the reservoir.
The transverse opening in the valve portion 32 is so disposed that it will align the tube 24 when the float 44 is raised, whereas the opening in the transverse opening in the valve portion 34 is so located as to align the tube 24 only when its associated float 46 is lowered.
In practical use of the invention, shown in Figures 1 through 6, inclusive, a suitable detergent, of liquid form or a soluble dissolved in liquid, is placed in the reservoir through the filling opening 14. Both floats 44 and 46 are raised since the water in the flush tank is at its normally high level. Therefore, the upper valve member 36 is in its open position and the lower valvemember 38 is in its closed position.
The detergent in reservoir 10 will gravitate into the tube 24 past the valve portion 32, into chamber 52 and will be retained above closed valve member 38. However, as the fiushing operation occurs, the level of the water in tank T will recede below the valve portion 34 and both floats 44 and 46 will move downwardly, due to their weight, in order to close the valve portion 32 and open the valve portion 34. During this phase, the detergent between the valve. portions 32 and 34 will pass into the tank to mix with the water as the water assumes its normal level. Furthermore, as the water in the tank T assumes its normal level, valve portion 32 will be moved by float 44 to its open position and valve portion 34 will be moved by its float 46 to a closed. position.
Obviously, suitable means is employed for retaining the valve portions relative to the tube 24. This means may Fat nted Feb. 28, 1956 a assume the form of a pair of spaced, split rings 60 and 62 yieldingly received in grooves in the valve portions so as to restrict axial movement of the portions 32, 34. Portion 32 includes a passage forming an air vent to the interior oftube 24 below portion 32 when portion 32 is moved to its closed position.
Attention is now directed to Figures 7, 8 and 9 wherein there is illustrated the present invention in modified form. In this embodiment, the valve member is designated by the numeral 100 and comprises a rigid shank 102 having a threaded connection with the socket portion 104 of a float 106.
The end of shank portion 102 remote from the float 106 is formed with an attaching element 112 having a bifurcated portion 114 that is pivoted to an ear 1.16 at the lower end of the vertical tube 24a.
Again, the upper end of the tube 24:: is coupled to a discharge or outlet nipple 18a of a reservoir or flush tank cover 10a which is filled with a detergent or detergent solution.
When the liquid in the tank Ta, covered by the reservoir 10a, is raised to its normal level, as shown in Figure 7, the valve member 100 will be raised to its closed position to prevent the detergent from passing into the tank. However, during the flushing operation, the level of water will recede and permit opening of the valve member so that the detergent will pass into the tank until the float 106 is raised in response to the liquid in the tank.
The form of the invention illustrated in Figures 10 and 11 is next to be considered. In this embodiment, the vertical tube 24b is again attached at its upper end to the discharge nipple 18b of a reservoir 10b that is retained on the upper edge of the flush tanks peripheral wall Tb.
A cage element 200 is formed at its upper end with an inner ring portion 202 that encircles the reduced end of the tube 24b to restrict upward movement of the cage element. The valve comprises a floatable ball 204 confined within the cage that will close the lower end of the conduit when the water level is raised to its normal position and which will open the lower discharge end of conduit 2411 when the water descends to its lower level during the flushing operation, in order that the detergent may pass into the tank Tb.
Figures 12, 13 and 14 show the invention in still further modified form. In this embodiment, the vertical supply tube 24c is attached at its upper end to the delivery nipple 180 of the flush tank cover or reservoir 10c and the lower end of tube 24c is formed with a conical discharge orifice 300.
A guide composed of two vertical rods 302 is attached at their upper ends to the lower end of tube 240 and slidably receive channels 304 secured to diametrically opposite sides of a valve member 306 having a hollow floatable disk 308 that supports a conical element 310.
When the liquid level of the tank Tc is normal, element 310 enters aperture 300 to close the same, however, as the liquid level lowers, as a result of the flushing operation, Valve member 306 will slide downwardly to its open position to permit detergent in tank 100 to pass into the tank to mix with the flush tank water as the latter rises in the tank.
